Description

  The present invention relates to a joint structure between columns introduced into a structure.

  Conventionally, a damping mechanism disclosed in Patent Document 1 has been proposed for the purpose of efficiently absorbing large vibration energy such as a large earthquake and preventing damage to structural members of a building.

  The vibration control mechanism disclosed in Patent Document 1 is configured by connecting the friction members via a friction damper so that the bent members of the pair of frame members have a substantially X shape. The upper and lower connecting plates are fixed to the base and the beam, and the direct material is fixed to the column. Thereby, the seismic control mechanism disclosed in Patent Document 1 absorbs the vibration energy by the friction damper when a large earthquake or the like occurs, and prevents the column from being pulled out or pulled in.

JP 2001-336303 A Japanese Patent No. 5422074

  However, the vibration control mechanism disclosed in Patent Document 1 uses a pair of bent member frame members, and uses the frictional resistance of the friction damper by the pressing force acting on the pair of frame members. For this reason, when the pressing force acting on the pair of frame members becomes insufficient, there is a problem that vibration energy cannot be sufficiently absorbed and the building may collapse.

  Moreover, since the seismic control mechanism disclosed in Patent Document 1 uses a pressing force acting on a frame member of a pair of bent members, it is applied when a brace member is not provided in a building. There was a problem that the building could not be able to be absorbed, vibration energy due to a large earthquake or the like could not be sufficiently absorbed, and the building could collapse.

  Furthermore, the vibration control mechanism disclosed in Patent Document 1 is applied only to the position where the brace material is provided, even when the brace material is provided in the building. There was a problem that energy could not be absorbed sufficiently and the building could collapse.

  Further, in Patent Document 2, a pair of first members such as an iron plate, a steel plate, and a stainless steel plate are provided in a pair substantially parallel to each other with a predetermined interval protruding from the end of the face material in the in-plane direction. The second member such as aluminum is sandwiched between the pair of first members, and the building is caused by an earthquake or the like by the peristalsis in the state where the first member and the second member are in contact with different materials. A technique is disclosed that absorbs vibrations acting on the surface by friction damping to prevent the collapse of the building and the collapse of the face material.

  However, in the disclosed technique of Patent Document 2, the second member is first welded and fixed in the vertical direction to a vertically formed columnar structure, and the welded second member On the other hand, a more preferable configuration connected to the first member formed in a columnar shape is not specifically disclosed. In addition, a press-fit portion that is press-fitted into the gap between the first member and the bolt shaft is formed in the interposition structure, so that a support pressure is applied between the first member and the interposition structure, and this support is supported. A configuration that resists vibration caused by an earthquake according to pressure has not been proposed in the past. In addition, by inserting the interposition structure into the first member, a supporting pressure is applied between the first member and the interposing structure, and resistance to vibration caused by an earthquake is generated according to the supporting pressure. Such a configuration has not been proposed in the past.

  Therefore, the present invention has been devised in view of the above-mentioned problems, and the object of the present invention is not affected by this even when it is fixed to the support by welding first. An object of the present invention is to provide a joint structure between columns that can sufficiently absorb vibration energy caused by a large earthquake or the like.

The joint structure between members according to claim 6 is formed in a columnar shape, a first member in which a first through hole is formed, and a structure formed in a columnar shape above or below the first member. A first member fixed to the body and having a second through hole formed therein, and a first member having a diameter smaller than that of the first through hole formed in the first member and fitted into the first through hole. The inner structure and the second through hole formed in the second member are reduced in diameter and fitted into the second through hole, and are in contact with the surface of the first interposition structure. It is provided with a 2nd intervention structure, and a fastening member which fastens these by penetrating the axis of a bolt in each hole of the 1st intervention structure and the 2nd intervention structure at least. .

  According to a seventh aspect of the present invention, in the invention according to the sixth aspect, the first member is interposed between the two second members, and the second interposed structure is either It is fitted in the 2nd through-hole in one or both said 2nd members.

  The joint structure between the members according to claim 8 is the invention according to claim 6 or 7, wherein the first interposed structure is fastened to the fastening member, so that the hole of the second interposed structure is formed. A first press-fitted portion that is press-fitted between the bolt and the bolt shaft is formed.

  The joining structure between members according to claim 9 is the invention according to claim 6 or 7, wherein the second interposed structure is fastened to the fastening member, so that the hole of the first interposed structure is formed.

  According to the present invention having the above-described configuration, when vibration due to an earthquake is applied to a structure, the first member formed in a columnar shape is directed in the vertical direction relative to the structure formed in the columnar shape. In other words, it vibrates and displaces in the in-plane direction of the first member. In such a case, the second member fixed to the structure and further the interposition structure fitted into the second member are displaced relative to the first member. Actually, the shaft of the bolt inserted in the through hole in the interposition structure reciprocates in the vertical direction in the hole in the first member in response to the earthquake. At this time, the intervening structure is in a state of being pressed against the surface of the first member. However, according to the vertical displacement in the hole by the shaft of such a bolt, the intervening structure is in the state of the first member. It will slide on the surface. That is, the interposed structure is alternately slid in the vertical direction on the paper surface while being pressed by the first member. As a result, friction acts between the surface of the first member and the interposed structure that presses against the surface of the first member. In addition, since the interposed structure is slightly reduced in diameter than the through hole, when the vibration due to the earthquake is applied to the structure, the interposed structure is vertically aligned in the through hole of the second member. It will vibrate relatively. At this time, the interposition structure collides with the through hole of the second member, and collision energy acts between the interposition structure and the through hole of the second member. As a result, vibration energy due to an earthquake is absorbed not only by frictional energy due to such friction but also by such collision energy.

  Hereinafter, an embodiment for carrying out a joining structure 100 between pillars to which the present invention is applied will be described in detail with reference to the drawings.

  A joining structure 100 to which the present invention is applied is applied to a joining structure between two column bodies as shown in FIG. In this joint structure 100, a column body 41 as a so-called round steel pipe that is formed in a column shape and extends in a substantially vertical direction is provided with a second member 26 that is extended so that the in-plane direction becomes the vertical direction. The column 41 is formed by welding two round steel pipes at a factory. Below the column body 41, a first member 43 formed of a so-called round steel pipe formed in a columnar shape and extending in a substantially vertical direction is provided. Thus, the joining structure 100 is a joining structure in which the column body 41 and the first member 43 are each used as a steel pipe pile.

  FIG. 2 shows a detailed cross-sectional view of such a joint structure 100.

  The first member 43 has a through-hole 101 formed therein. The shaft of the bolt 63 is inserted into each hole 101. The first member 43 is made of any kind of metal such as steel, aluminum, stainless steel, brass or the like. In the first member 43, two round steel pipes are welded and joined at the factory, and the lower side is buried in the ground G and fixed. An upper end portion of the first member 43 is in contact with a lower end portion of the column body 41.

  The second member 26 is fixed to the column body 41 by welding before the first member 43 is joined. The second member 26 is configured by a round steel pipe having a circular cross section. Specifically, the second member 26 a is attached to the outer peripheral surface of the column body 41 by welding, and is attached to the inner peripheral surface of the column body 41 by welding. It is comprised by the 2nd member 26b. The first member 43 is interposed between the second member 26a and the second member 26b. The second members 26a and 26b have an inner surface 28 fixed to the outer peripheral surface of the column body 41 and an outer surface 29 formed on the opposite side of the inner surface 28, with the lower end portion of the outer surface 29 as the top. An inclined surface 34 that is inclined upward toward the inner surface 28 is formed. Thereby, the first member 43 can be interposed in the second members 26a and 26b along the inclined surface 34, and the installation thereof becomes easy.

  A through hole 33 is formed in the second members 26a and 26b. The interposition structure 62 is fitted in each of the through holes 33. The interposition structure 62 is composed of a steel plate, an aluminum plate, a stainless steel plate, a lead plate, a tin plate, a beryllium plate, a copper plate, a brass plate, an alloy plate of these metals, a resin, a rubber, a resin plate, or the like. The interposition structure 62 is formed so that a through hole 62d is formed substantially at the center to form a so-called ring. The outer shape and size of the interposition structure 62 are in accordance with the shape and size of the through hole 33 of the second member 26 into which the interposed structure 62 is fitted. That is, if the through hole 33 is circular, the outer shape of the interposition structure 62 is a circular shape that is slightly smaller in diameter than the through hole 33. Similarly, if the through hole 33 has a square shape, the outer shape of the interposition structure 62 also has a similar square shape with a slightly smaller diameter than the through hole 33. Furthermore, the thickness of the interposition structure 62 may be any thickness, but in the example of FIG. 2, the thickness is such that it does not protrude from the surfaces of the second members 26a and 26b.

  The shaft of the bolt 63 is inserted through the through hole 62 d in the interposition structure 62 and the hole 101 in the first member 43. The shaft tip of the bolt 63 is screwed with a nut 64. By performing such tightening with the bolt 63 and the nut 64, the compressive force generated between the head of the bolt 63 and the nut 64 by the compressive force from the head of the bolt 63 is interposed in the second member 26a. It will be transmitted through the interposition structure 62 in the structure 62, the 1st member 43, and the 2nd member 26b. As a result, it can be fixed in a state in which a pressing force is applied from the interposition structure 62 to both surfaces of the first member 43. The interposition structure 62 provided in the second member 26 b is fitted into the through hole 33 and spot welded to the through hole 33. The nut 64 is provided inside the first member 43, and is spot-welded and fixed to the interposition structure 62 in advance before the first member 43 and the second member 26 are joined. Thereby, the head of the bolt 63 is disposed outside the first member 43, and the bolt 63 can be screwed onto the nut 64. The interposition structure 62 that has been spot welded to the through hole 33 of the second member 26 b is detached from the through hole 33 by fastening the bolt 63. Note that so-called high-strength bolt joining may be performed between the bolt 63 and the nut 64.

  Next, the function and effect of the present invention having the above-described configuration will be described.

  When vibration due to an earthquake is applied to the structure, the first member 43 vibrates and displaces in the vertical direction relative to the column 41, in other words, in the in-plane direction of the first member 43. It will be. In such a case, the first member 43 is displaced relatively with respect to the interposition structure 62 fitted into the through hole 33 of the second member 26. Actually, the shaft of the bolt 63 inserted into the through hole 62d in the interposition structure 62 reciprocates in the vertical direction with respect to the hole 101 in the first member 43 in response to the earthquake. . At this time, the intervening structure 62 is pressed against the surface of the first member 43, but the intervening structure 62 is in contact with the first member 43 according to the force to be displaced vertically. Will slide on the surface. In other words, the interposition structure 62 shown in FIG. 2 is alternately slid in the vertical direction on the paper surface while being pressed by the first member 43. As a result, friction acts between the surface of the first member 43 and the interposition structure 62 that presses against the surface of the first member 43. And the vibration energy by an earthquake will be absorbed by friction damping according to this friction. In addition, since the interposed structure 62 is slightly reduced in diameter than the through hole 33, when vibration due to an earthquake is applied to the structure, the interposed structure 62 is inserted into the through hole 33 of the second member 26. It will vibrate relatively in the vertical direction. At this time, the interposed structure 62 collides with the through hole 33 of the second member 26, and collision energy acts between the interposed structure 62 and the through hole 33 of the second member 26. . As a result, vibration energy due to an earthquake is absorbed not only by frictional energy due to such friction but also by such collision energy.

  Therefore, the present invention can be embodied as a joint structure 100 that can sufficiently absorb vibration energy due to a large earthquake or the like.

  In particular, according to the present invention, since the first member 43 and the interposition structure 62 are made of different materials, they can be slid together in a different material contact state. Here, the dissimilar material contact state is a dissimilar metal contact state in which iron or steel and aluminum are in contact, a dissimilar metal contact in which iron or steel and brass are in contact, or a dissimilar metal in which iron or steel and stainless are in contact. A contact state, a dissimilar material contact state in which an iron or steel material and a resin containing metal powder are in contact, a dissimilar material contact state in which an iron or steel material and a resin or rubber not containing metal powder are in contact, and the like. That is, the dissimilar material contact state may be anything as long as the materials constituting the first member 43 and the interposition structure 62 are different. Thereby, it becomes possible to make the friction damping mentioned above act more effectively. In particular, by forming a different material contact state between an iron plate, a steel plate, etc. and an aluminum plate, the friction force can be applied more strongly due to the difference in the friction coefficient of each other, and more friction damping can be applied. It becomes. Note that at least the contact surfaces of the first member 43 and the interposition structure 62 are made of different materials, except when the first member 43 itself and the interposition structure 62 themselves are made of different materials. Just do it. Thus, it goes without saying that the above-described effects can be obtained.

  By improving the smoothness of the first member 43, the interposition structure 62, and the contact surface, when these are swung in contact with different materials, aluminum or the like is present between the iron plate, the steel plate, and the aluminum plate. A portion that melts partially in an iron plate, a steel plate, and the like, and where the metal particles are integrated to form an interface without forming an interface. As a result, in the joint structure 100 to which the present invention is applied, it is possible to obtain a significantly higher coefficient of friction than the frictional resistance that forms the interface, and to significantly improve the absorption performance against vibration acting on the building. It is possible to reliably prevent the collapse of objects and the collapse of face materials.

  According to the present invention, the second members 26a and 26b are first joined to the column body 41 by welding, and then the first member 43 is interposed between the second members 26a and 26b, respectively. The interposition structure 62 is fitted in the 33 and fixed with bolts 63 and nuts 64. At this time, there may be a positional deviation or construction error when welding the second member 26 to the column body 41, and as a result, a gap may be generated between the second member 26 and the first member 43. is there. The total sum of the gaps is α. That is, α is represented by the sum of the width between the first member 43 and the second member 26a and the width between the first member 43 and the second member 26b.

  Here, assuming that the thickness of the interposition structure 62 is t, it is assumed that t> α. As a result, even when a positional shift or construction error occurs when welding the second member 26 to the column body 41, the thickness t of the interposition structure 62 does not fall below α. It is possible to steadily transmit the vibration from 26 to the first member 43 via the interposition structure 62.

  FIG. 3 shows another embodiment of the joining structure 100 to which the present invention is applied. In this example, the thickness of the interposition structure 62 is further increased. Specifically, the thickness of the interposed structure 62 is increased so as to protrude outward from the second members 26a and 26b. Even in such a case, the thickness t of the interposition structure 62 is set so as to satisfy the condition of t> α, so that the vibration from the second members 26a and 26b is caused to pass through the interposition structure 62 through the first. It becomes possible to convey to the member 43 steadily. In such a configuration, the washer 111 is interposed between the head of the bolt 63 and the interposed structure 62 and between the nut 64 and the interposed structure 62. The washer 111 is fixed to the interposition structure 62 and the nut 64 by spot welding before the first member 43 is joined.

  Further, according to the embodiment shown in FIG. 3, since the thickness of the interposition structure 62 is increased with respect to the thickness of the second member 26, the effects described below are achieved. . That is, it is difficult to adjust and weld the second member 26 to the column body 41 without any dimensional error. Usually, as shown in FIG. 3, the interval between the second members 26 a and 26 b is often configured wider than the plate thickness of the first member 43. In such a case, the first member 43 is loosely fitted between the second members 26a and 26b. In such a state, the gap between the first member 43 and one second member 26a is α1, the gap between the first member 43 and the other second member 26b is α2, and the second member The plate thickness of the interposition structure 61-1 fitted in the member 26a is t1, and the plate thickness of the interposition structure 61-2 fitted in the through hole formed in the other second member 26b is t2. It is essential that α1 <t1 and α2 <t2. Thereby, it becomes possible to absorb the error of the dimension with respect to the attachment position to the column 41 in the 2nd member 26. FIG.

  FIG. 4 shows an example in which the interposition structure 62 is configured with a two-layer structure. In this example, the interposition structure 62 is configured by a first layer 62 a that contacts the first member 43 and a second layer 62 b that contacts the bolt 63 and the nut 64. Incidentally, the meaning of the second layer 62b contacting the bolt 63 and the nut 64 includes contacting the fastening member such as the bolt 63 and the nut 64 via the washer 111 described above.

  Here, the first member 43 and the first layer 62a are made of different materials. Thereby, these can also be slid mutually with the dissimilar material contact state mentioned above. That is, this dissimilar material contact state may be anything as long as the materials constituting the first member 43 and the first layer 62a are different. Thereby, it becomes possible to make the friction damping mentioned above act more effectively. In particular, the first member 43 is made of an iron plate, a steel plate, etc., and the first layer 62a is made of an aluminum plate, a plate material made of aluminum alloy, copper alloy, bronze, stainless steel, etc. A contact state can be formed. At this time, the contact surfaces of the first member 43 and the first layer 62a may be made of at least different materials.

  FIG. 5 shows an example in which an internal thread 62 c capable of screwing the foot of the bolt 63 is formed inside the interposition structure 62. A hole is formed substantially at the center of the interposition structure 62, and a female screw 62c is formed on the inner wall of the hole. By adopting such a configuration, it is not necessary to provide the nut 64, and it is possible to reduce the construction cost and facilitate the construction by reducing the number of parts. In addition, you may make it substitute with the bolt 63 mentioned above with the nut 64 equivalent to the head of the bolt 63, and the screw rod 201 which can be screwed together. The planar form of the intervening structure 62 may be configured in a polygonal shape other than a circle, and in particular when it is a polygonal shape, it is possible to prevent rotation.

  FIG. 6 shows an example in which the configuration of the second member 26 b is omitted, and the joining is performed only between the second member 26 a and the first member 43. The bolt 63 is inserted from the outside of the first member 43, and the upper end of the bolt 63 protruding from the interposition structure 62 and the washer 111 is screwed and fixed by the nut 64. The nut 64 is fixed to the first member 43 by spot welding before joining the first member 43 and the second member 26.

  7 to 12 show modifications of the present invention. In these modified examples, the same members and components as those described above are denoted by the same reference numerals, and the following description is omitted.

  In the example of FIG. 7, an example in which a thick washer 362 is interposed as an alternative to the interposed structure 62 is shown. The thick washer 362 is integrally formed continuously up to the second member 26a, the first member 43, and the second member 26b, and both ends thereof are fastened by bolts 63 and nuts 64 through washers 111. The

  In the example of FIG. 8, an example in which the interposition structure 62 is configured by three washers 363a, 363b, and 363c is shown. When the plate thickness of the second member 26 is thick, by laminating such washers 363a to 363c, the total thickness of the laminate can be made larger than the plate thickness of the second member 26.

  The example of FIG. 9 shows an example in which the washer 363a has a shape that is gradually reduced in diameter toward the center, in other words, a substantially conical shape. The shape of the washer 363a may be a curved surface that is convex outward. The washer 363b fitted to the washer 363a is also formed with a recess capable of fitting its conical shape, and has a shape gradually reduced in diameter toward the center, in other words, a substantially conical shape. The outermost washer 363c is also formed with a recess that can be fitted with a conical protrusion of the washer 363b. With such a configuration, centering when the washers 363a to 363c are stacked and arranged can be realized with high accuracy.

  In FIG. 10, the second interposed structure 62-2 is fitted into the through hole 33 provided in the second member 26a, and the first interposed structure 62− is inserted into the through hole 133 provided in the first member 43. An example in which 1 is inserted is shown. The first intervention structure 62-1 and the second intervention structure 62-2 are in contact with each other. The second interposed structure 62-2 is configured to have a larger diameter than the first interposed structure 62-1. At least the first interposition structure 62-1 and the second interposition structure 62-2 are fastened to each other by passing the shafts of the bolts 63 through the holes. In the case where the first interposition structure 62-1 and the second interposition structure 62-2 are formed of separate members, the second interposition structure 62-2 is configured to have a larger diameter. The diameter of the 1 intervening structure 62-1 may be configured to be smaller than this. As a result, when the bolt 63 and the nut 64 are fastened and fixed, the stress can be concentrated toward the first intervening structure 62-1, and thus stable bolt fixing can be realized. Further, the first intervention structure 62-1 and the second intervention structure 62-2 may be configured to have the same diameter, and the second intervention structure 62-2 may be configured as the first intervention. Of course, the diameter may be smaller than that of the mounting structure. Moreover, you may make it comprise the 1st intervention structure 62-1 and the 2nd intervention structure 62-2 by the same member, without mutually isolate | separating. Moreover, the 1st intervention structure 62-1 may be comprised so that fitting with respect to the 2nd intervention structure 62-2 is possible.

  In the configuration shown in FIG. 10 as well, similarly, the first interposition structure 62-1 is alternately slid in the vertical direction on the paper surface while being pressed by the second member 26b. As a result, friction acts between the surface of the second member 26b and the first interposed structure 62-1 that presses against the surface of the second member 26b. And the vibration energy by an earthquake will be absorbed by friction damping according to this friction. Further, the first interposed structure 62-1 vibrates in the up-down direction on the paper surface in the through hole 133 and the second interposed structure 62-2 in the through hole 33, respectively. Thereby, since the 1st intervention structure 62-1 collides with the through-hole 133 and the 2nd intervention structure 62-2 collides with the through-hole 33, vibration energy will be absorbed by collision energy. .

  Incidentally, the second member 26b is not provided with the specially provided second interposed structure 62-2. However, the present invention is not limited to this, and the second interposed structure 62- is not limited to the second member 26b. 2 may be provided similarly. In such a case, the second interposed structure 62-2 provided on the second member 26b is disposed so as to contact the first interposed structure 62-1 described above. Even in such a case, the diameter of the second interposed structure 62-2 may be smaller than that of the first interposed structure 62-1 or may be increased with respect to the second member 26b. May be.

  FIG. 11 shows an example in which the configuration of the second member 26 b is omitted in the form of FIG. 10 and the joining is performed only between the second member 26 a and the first member 43. The bolt 63 is inserted from the outside of the first member 43, and the interposed structure 62 and the bolt 63 protruding from the washer 111 are screwed and fixed by the nut 64. Similarly, in this embodiment, the second interposed structure 62-2 is fitted into the through hole 33 provided in the second member 26a, and the first interposed structure is inserted into the through hole 133 provided in the first member 43. The body 62-1 is fitted, and the first interposed structure 62-1 and the second interposed structure 62-2 are in contact with each other. In this example, it is needless to say that the above-described effects can be obtained.

  In FIG. 12, the interposition structure 62 is fitted into the second members 26a and 26b, and the interposition structure 62 is brought into contact with the first member 43 sandwiched between the second members 26a and 26b. is there. However, the second members 26 a and 26 b are not directly fixed to the column body 41 by welding, but are attached to the column body 41 via bolts 63 and nuts 64. The second members 26a and 26b are attached to the second members 26a and 26b via spacers 763. Further, the spacer 763 is not particularly essential and may be omitted. Even in such a configuration, since the second member 26 is fixed to the column body 41 before the first member 43, the same effect as described above can be obtained.

  Note that when fitting the interposition structure 62 into the through hole 33, a liquid (adhesive, lubricant) may be injected between the through hole 33 and the interposition structure 62. When an adhesive is used as the liquid, for example, a two-component type composed of a silicon adhesive and an epoxy adhesive may be used. Further, in order to further reduce the difference in diameter, a lubricant may be used and injected on site. Thereby, the operation | work which fits the interposition structure 62 in the through-hole 33 becomes easy.

  Further, according to the present invention, the interposed structure 62 may be inserted into the through-hole 33 while being cooled, and then the diameter difference may be almost the same when both are at the same temperature. That is, the material constituting the interposition structure 62 contracts due to cooling, but when the temperature rises thereafter, the contracted material expands. Using this phenomenon, when fitting into the through-hole 33, by reducing the diameter of the interposed structure 62 by cooling, the ease of fitting is improved, and then the temperature naturally rises from the cooling state, The interposition structure 62 fitted in the through hole 33 swells.

  FIG. 13 shows an example in which a first member 43 composed of a so-called steel pipe column provided in a substantially vertical direction is provided above the column body 41. Also in this example, the second member 26 is configured such that the interposition structure 62 is fitted in the through hole, and the interposition structure 62 is in contact with the first member 43. The second members 26a and 26b have an inner surface 28 fixed to the outer peripheral surface of the column 41 and an outer surface 29 formed on the opposite side of the inner surface 28, with the upper end of the outer surface 29 as the top. An inclined surface 34 that is inclined downward toward the inner surface 28 is formed. Thereby, the first member 43 can be interposed in the second members 26a and 26b along the inclined surface 34, and the installation thereof becomes easy. Further, an interposing structure 62, a bolt 63 inserted through the second member 26, and a nut 64 screwed to the bolt 63 are provided. The bolt 63 is loosely fitted to the interposition structure 62, but is fitted to the hole provided in the column body 41 with almost no gap. In this form, α is similarly expressed as the sum of the width between the first member 43 and the second member 26a and the width between the first member 43 and the second member 26b, and the interposition structure. Assuming that the thickness of 62 is t, it is assumed that t> α. Note that any technical idea shown in FIGS. 1 to 12 may be reflected even in the case of assuming the configuration of FIG. 13 as described above.

  As described above, the structure that resists vibration energy such as a large earthquake by causing friction between the surface of the first member 43 and the interposition structure 62 that presses against the surface has been described.

  Next, what resists each other between the first member 43 and the interposition structure 62 that presses against the first member 43 will be described as one that resists vibration energy such as a large earthquake.

  As shown in FIG. 14, the bolt 63 is arranged so that its axis is substantially the center of the through hole 62 d in the interposition structure 62 and the hole 101 in the first member 43. The interposed structure 62 is fitted into the through hole 33 of the second member 26 and is in contact with the surface of the first member 43. The interposed structure 62 is spot-welded to the second member 26b. In the interposition structure 62, the first member 43 and the interposition structure 62 are made of different materials so that the yield point of the interposition structure 62 is smaller than the yield point of the first member. . The nut 64 is fixed to the second member 26b by welding in advance.

  A pressurizing body 69 is provided between the head of the bolt 63 and the interposition structure 62 and between the nut 64 and the interposition structure 62. The pressurizing body 69 is composed of a steel plate, an aluminum plate, a stainless steel plate, a brass plate, a resin, rubber, a resin plate, or the like. The pressurizing body 69 is formed so that a through-hole 69d is formed substantially at the center to form a so-called ring. The outer shape and size of the pressure member 69 are in accordance with the shape and size of the hole 101 of the first member 43. In other words, if the hole 101 is circular, the outer shape of the pressure member 69 is a circular shape formed to have substantially the same diameter as the hole 101. Similarly, if the hole 101 has a square shape, the outer shape of the pressurizing body 69 also has a similar square shape formed to have substantially the same diameter as the hole 101. Furthermore, the thickness of the interposition structure 62 may be any thickness, but in the example of FIG. 14, the thickness is such that it does not protrude from the surfaces of the second members 26a and 26b. The pressurizing body 69 is fixed by spot welding to the interposition structure 62 and the nut 64.

  As shown in FIG. 14, the compression force generated between the head of the bolt 63 and the nut 64 by tightening with the bolt 63 and the nut 64 causes the interposition structure 62 in the second member 26 a, the first It is transmitted through the interposing structure 62 in the member 43 and the second member 26b. As a result, it can be fixed in a state in which a pressing force is applied from the interposition structure 62 to both surfaces of the first member 43. Note that so-called high-strength bolt joining may be performed between the bolt 63 and the nut 64.

  Further, since the interposition structure 62 is slightly smaller in diameter than the through hole 33, it is further elastically deformed or plastically deformed by tightening with the bolt 63 and the nut 64, and comes into contact with the through hole 33. Will be. Further, since the interposed structure 62 has a diameter slightly larger than the axis of the bolt 63, the interposed structure 62 is elastically deformed or plastically deformed and comes into contact with the axis of the bolt 63. At this time, since the hole 101 of the first member 43 is larger in diameter than the shaft of the bolt 63, the interposition structure 62 is press-fitted into the gap between the hole 101 of the first member 43 and the shaft of the bolt 63. The press-fitting part 67 is formed. That is, in the interposition structure 62, the press-fit portion 67 formed by elastic deformation or plastic deformation is brought into contact with the hole 101 of the first member 43 and the shaft of the bolt 63.

  Next, the function and effect of the present invention having the above-described configuration will be described.

  When vibration due to an earthquake is applied to the structure, the column body 41 vibrates and displaces in the vertical direction, in other words, in the in-plane direction of the first member 43. In such a case, the press-fit portion 67 of the interposition structure 62 fitted into the through hole 33 of the second member 26a, 26b is press-fitted into the gap between the hole 101 of the first member 43 and the shaft of the bolt 63. At this time, the support structure 62 tries to resist the force to be displaced vertically, and a support pressure acts between the hole 101 of the first member 43 and the press-fit portion 67 of the support structure 62. Become. Thereby, the interposition structure 62 is not displaced relative to the first member 43. At the same time, since the interposition structure 62 is in contact with the through hole 33, a bearing pressure acts between the through hole 33 of the second members 26 a and 26 b and the interposition structure 62. . As a result, the interposition structure 62 is not displaced relative to the second members 26a and 26b. Thus, it will resist the vibration caused by the earthquake according to these bearing pressures. In particular, when vibration due to an earthquake is applied, the column body 41 is not relatively displaced with respect to the first member 43, thereby preventing collision and rattling between the column body 41 and the first member 43.

  Therefore, the present invention can be embodied as a joint structure 100 capable of resisting vibration energy due to a large earthquake or the like by supporting pressure.

  Further, pressure bodies 69 are provided between the head of the bolt 63 and the interposition structure 62 and between the nut 64 and the interposition structure 62, respectively. As a result, the pressing body 69 can apply a concentrated load to the interposition structure 62 by tightening with the bolt 63 and the nut 64. In particular, the outer shape and size of the pressure member 69 are in accordance with the shape and size of the hole 101 of the first member 43. For this reason, the pressurizing body 69 can prompt the formation of the press-fitting portion 67 press-fitted into the interposition structure 62 into the gap between the hole 101 of the first member 43 and the shaft of the bolt 63. In the case described above, the pressurizing body 69 and the interposition structure 62 may be made of different materials so that the yield point of the interposition structure 62 is smaller than the yield point of the pressurization body 69. desirable. In the present invention, the configuration of the pressurizing body 69 may be omitted. This is because even when the configuration of the pressurizing body 69 is omitted, the pressing force when the bolt 63 and the nut 64 are fastened is transmitted to the interposition structure 62, and the press-fit portion 67 is formed. Because it will be.

  FIG. 15 shows another embodiment of the joining structure 100 to which the present invention is applied. An interposition structure 162 is fitted into the through hole 33 of the second member. The interposition structure 162 includes a pressurizing portion 169 having a reduced diameter as the distance from the first member increases. The outer shape and size of the upper end of the pressure unit 169 are in accordance with the shape and size of the hole 101 of the first member 43. Such a pressure part 169 can apply a concentrated load to the interposition structure 162 by tightening with the bolt 63 and the nut 64. As a result, the pressurizing part 169 can prompt the formation of the press-fitting part 167 that is press-fitted into the gap between the hole 101 of the first member 43 and the shaft of the bolt 63 in the interposition structure 162.

  In FIG. 16, the second interposed structure 62-2 is fitted into the through hole 33 provided in the second member 26a, and the first interposed structure 62− is inserted into the through hole 133 provided in the first member 43. An example in which 1 is inserted is shown. In such a case, the first intervening structure 62-1 and the second intervening structure 62-1 are arranged so that the yield point of the second intervening structure 62-2 is smaller than the yield point of the first intervening structure 62-1. The mounting structure 62-2 is made of different materials. The first intervention structure 62-1 and the second intervention structure 62-2 are in contact with each other. The inner diameter of the first interposed structure 62-1 is larger than the diameter of the bolt 63. The inner diameter of the second interposed structure 62-2 is slightly larger than the shaft of the bolt 63. The outer diameter of the second interposed structure 62-2 is configured to be larger than the outer diameter of the first interposed structure 62-1. At least the first interposition structure 62-1 and the second interposition structure 62-2 are fastened to each other by passing the shafts of the bolts 63 through the holes. A pressurizing body 69 is provided between the second interposed structure 62 and the nut 64. The first intervention structure 62-1 and the second intervention structure 62-2 may be configured to have the same outer diameter, or the second intervention structure 62-2. Of course, the outer diameter may be smaller than the outer diameter of the first intervening structure.

  Even in such a state, by tightening with the bolt 63 and the nut 64, the first interposition structure 62-1 is elastically deformed or plastically deformed, and the through hole 133 is formed. Abutted. Further, the second interposed structure 62-2 is elastically deformed or plastically deformed and comes into contact with the through hole 33. At this time, the second interposed structure 62-2 is press-fitted into the gap between the hole of the first interposed structure 62-1 and the shaft of the bolt 63 to form the second press-fit portion 67-2. Become. As a result, the second interposed structure 62-2 has a second press-fit portion 67-2 in contact with the hole of the first interposed structure 62-1 and the shaft of the bolt 63. In order to resist the force to be displaced, a support pressure acts between the hole of the first interposition structure 62-1 and the second press-fit portion 67-2. As a result, the second interposed structure 62-2 is not displaced relative to the first interposed structure 62-1. In addition, since the 2nd interposed structure 62-2 is contact | abutted to the through-hole 33, between the through-hole 33 of the 2nd members 26a and 26b and the 2nd interposed structure 62-2, it is mutually. The bearing pressure will act. As a result, the second interposed structure 62-2 is not displaced relative to the second members 26a and 26b. Thus, it will resist the vibration caused by the earthquake according to these bearing pressures.

  17, the second interposed structure 62-2 is fitted into the through hole 33 provided in the second member 26a, and the first interposed structure 62− is inserted into the through hole 133 provided in the first member 43. Another example in which 1 is inserted is shown. In such a case, the first intervening structure 62-1 and the second intervening structure 62-2 are arranged such that the yield point of the second intervening structure 62-2 is larger than the yield point of the first intervening structure 62-1. The mounting structure 62-2 is made of different materials. The first intervention structure 62-1 and the second intervention structure 62-2 are in contact with each other. The inner diameter of the first interposed structure 62-1 is slightly larger than the shaft of the bolt 63. The inner diameter of the second interposed structure 62-2 is larger than the diameter of the bolt 63. The outer diameter of the second interposed structure 62-2 is configured to be larger than the outer diameter of the first interposed structure 62-1. At least the first interposition structure 62-1 and the second interposition structure 62-2 are fastened to each other by passing the shafts of the bolts 63 through the holes. Further, the outer diameter of the first interposed structure 62-1 and the outer diameter of the second interposed structure 62-2 may be configured by the same diameter, or the second interposed structure 62 may be configured. Of course, the outer diameter of -2 may be smaller than the outer diameter of the first intervening structure.

  Even in such a state, by tightening with the bolt 63 and the nut 64, the first interposed structure 62-1 can be connected to the holes and bolts of the second interposed structure 62-2. The first press-in portion 67-1 is formed by being press-fitted into the gap with the shaft 63. As a result, the first interposition structure 62-1 has a vertical position because the first press-fit portion 67-1 is in contact with the hole of the second interposition structure 62-2 and the shaft of the bolt 63. In order to resist the force to be displaced, a support pressure acts between the hole of the second interposed structure 62-2 and the first press-fit portion 67-1. Thereby, the 1st intervention structure 62-1 will not be displaced relatively to the 2nd intervention structure 62-2. In addition, since the 1st intervention structure body 62-1 is contact | abutted to the through-hole 133, a support pressure mutually acts between the through-hole 133 and the 1st intervention structure body 62-1. Become. Thereby, the first interposition structure 62-1 is not displaced relative to the first member 43. Thus, it will resist the vibration caused by the earthquake according to these bearing pressures.

  Incidentally, in the form of FIG. 16 and the form of FIG. 17, the second member 26 b is not provided with a special intervening structure, but is not limited to this, and the second member 26 b is interposed. You may make it provide a structure similarly. In such a case, the intervention structure provided on the second member 26b is arranged so as to contact the first intervention structure 62-1. Even in such a case, the diameter of the interposed structure 62 relative to the second member 26b may be smaller than that of the first interposed structure 62-1, or may be increased.

  14 to 17, the configuration of the second member 26 b may be omitted, and the second member 26 a and the first member 43 may be joined only. Also, in the case of assuming the configurations of FIGS. 14 to 17, any technical idea shown in FIGS. 1 to 13 may be reflected.

  FIG. 18 shows another embodiment of the joint structure 100 to which the present invention is applied. In this example, the first member 43 and the interposition structure 62 are made of different materials so that the yield point of the interposition structure 62 is larger than the yield point of the first member. In this configuration, the interposition structure 62 is elastically deformed or plastically deformed by tightening with the bolt 63 and the nut 64, and comes into contact with the through hole 33. At this time, the interposition structure 62 is inserted into the first member 43 due to plastic deformation of the first member 43.

  When vibration due to an earthquake is applied to the structure, the column body 41 vibrates and displaces in the vertical direction, in other words, in the in-plane direction of the first member 43. In such a case, the interposition structure 62 that is fitted into the through hole 33 of the second member 26 a, 26 b is fitted into the first member 43. At this time, since the interposition structure 62 is in contact with the first member 43 and the shaft of the bolt 63, the first member 43 and the interposition structure try to resist the force to be displaced vertically. The bearing pressure acts between the two members 62. Thereby, the interposition structure 62 is not displaced relative to the first member 43. At the same time, since the interposition structure 62 is in contact with the through hole 33, a bearing pressure acts between the through hole 33 of the second members 26 a and 26 b and the interposition structure 62. . As a result, the interposition structure 62 is not displaced relative to the second members 26a and 26b. Thus, it will resist the vibration caused by the earthquake according to these bearing pressures. In particular, when vibration due to an earthquake is applied, the first member 43 is not relatively displaced with respect to the second member 26, thereby preventing the first member 43 and the second member 26 from colliding or rattling.

  Further, pressure bodies 69 are provided between the head of the bolt 63 and the interposition structure 62 and between the nut 64 and the interposition structure 62, respectively. As a result, the pressing body 69 can apply a concentrated load to the interposition structure 62 by tightening with the bolt 63 and the nut 64. In particular, the outer shape and size of the pressure member 69 are in accordance with the shape and size of the through hole 33 of the second member. For this reason, the pressurizing body 69 can promote the intervention of the interposition structure 62 into the first member 43. In the case described above, the pressurizing body 69 and the interposition structure 62 may be made of different materials so that the yield point of the interposition structure 62 is smaller than the yield point of the pressurization body 69. desirable. In the present invention, the configuration of the pressurizing body 69 may be omitted. This is because even when the configuration of the pressurizing body 69 is omitted, the pressing force when the bolt 63 and the nut 64 are fastened is transmitted to the interposing structure 62, and the interposing structure 62 is This is because it is inserted into the one member 43.

  In FIG. 19, the second interposed structure 62-2 is fitted into the through hole 33 provided in the second member 26a, and the first interposed structure 62− is inserted into the through hole 133 provided in the first member 43. An example in which 1 is inserted is shown. In such a case, the first intervening structure 62-1 and the second intervening structure 62-1 are arranged so that the yield point of the second intervening structure 62-2 is smaller than the yield point of the first intervening structure 62-1. The mounting structure 62-2 is made of different materials. The first intervention structure 62-1 and the second intervention structure 62-2 are in contact with each other. The inner diameter of the first interposed structure 62-1 is larger than the diameter of the bolt 63. The inner diameter of the second interposed structure 62-2 is slightly larger than the shaft of the bolt 63. The outer diameter of the second interposed structure 62-2 is configured to be larger than the outer diameter of the first interposed structure 62-1. At least the first interposition structure 62-1 and the second interposition structure 62-2 are fastened to each other by passing the shafts of the bolts 63 through the holes. A pressurizing body 69 is provided between the second interposed structure 62 and the nut 64. The first intervention structure 62-1 and the second intervention structure 62-2 may be configured to have the same outer diameter, or the second intervention structure 62-2. Of course, the outer diameter may be smaller than the outer diameter of the first intervening structure.

  Even in such a state, by tightening with the bolt 63 and the nut 64, the first interposition structure 62-1 is elastically deformed or plastically deformed, and the through hole 133 is formed. Abutted. Further, the second interposed structure 62-2 is elastically deformed or plastically deformed and comes into contact with the through hole 33. At this time, the second interposed structure 62-2 is sunk into the first interposed structure 62-1. As a result, the second interposed structure 62-2 tries to resist the force to be vertically displaced, and the first interposed structure 62-1 and the second interposed structure 62-2 are mutually connected. The bearing pressure will act. As a result, the second interposed structure 62-2 is not displaced relative to the first interposed structure 62-1. In addition, since the 2nd interposed structure 62-2 is contact | abutted to the through-hole 33, between the through-hole 33 of the 2nd members 26a and 26b and the 2nd interposed structure 62-2, it is mutually. The bearing pressure will act. As a result, the second interposed structure 62-2 is not displaced relative to the second members 26a and 26b. Thus, it will resist the vibration caused by the earthquake according to these bearing pressures.

  20, the second interposed structure 62-2 is fitted into the through hole 33 provided in the second member 26a, and the first interposed structure 62− is inserted into the through hole 133 provided in the first member 43. Another example in which 1 is inserted is shown. In such a case, the first intervening structure 62-1 and the second intervening structure 62-2 are arranged such that the yield point of the second intervening structure 62-2 is larger than the yield point of the first intervening structure 62-1. The mounting structure 62-2 is made of different materials. The first intervention structure 62-1 and the second intervention structure 62-2 are in contact with each other. The inner diameter of the first interposed structure 62-1 is slightly larger than the shaft of the bolt 63. The inner diameter of the second interposed structure 62-2 is larger than the diameter of the bolt 63. The outer diameter of the second interposed structure 62-2 is configured to be larger than the outer diameter of the first interposed structure 62-1. At least the first interposition structure 62-1 and the second interposition structure 62-2 are fastened to each other by passing the shafts of the bolts 63 through the holes. Further, the outer diameter of the first interposed structure 62-1 and the outer diameter of the second interposed structure 62-2 may be configured by the same diameter, or the second interposed structure 62 may be configured. Of course, the outer diameter of -2 may be smaller than the outer diameter of the first intervening structure.

  Even in such a state, by tightening with the bolt 63 and the nut 64, the first interposed structure 62-1 can be connected to the holes and bolts of the second interposed structure 62-2. The first press-in portion 67-1 is formed by being press-fitted into the gap with the shaft 63. As a result, the first interposition structure 62-1 has a vertical position because the first press-fit portion 67-1 is in contact with the hole of the second interposition structure 62-2 and the shaft of the bolt 63. In order to resist the force to be displaced, a support pressure acts between the hole of the second interposed structure 62-2 and the first press-fit portion 67-1. Thereby, the 1st intervention structure 62-1 will not be displaced relatively to the 2nd intervention structure 62-2. In addition, since the 1st intervention structure body 62-1 is contact | abutted to the through-hole 133, a support pressure mutually acts between the through-hole 133 and the 1st intervention structure body 62-1. Become. Thereby, the 1st intervention structure 62-1 will not be displaced relatively to the 2nd intervention structure 62-2. Thus, it will resist the vibration caused by the earthquake according to these bearing pressures.

  Incidentally, in the form of FIG. 19 and the form of FIG. 20, the second member 26 b is not specifically provided with the second interposed structure 62-2, but is not limited to this, and the second member 26 b However, the second intervening structure 62-2 may be provided in the same manner. In such a case, the second interposed structure 62-2 provided on the second member 26b is disposed so as to contact the first interposed structure 62-1 described above.
