[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure provided with a member for increasing seismic strength, for example, a building and a seismic connection tool used therefor. In the present invention, the member means a material constituting a predetermined part of the structure. Further, in the following drawings, portions denoted by the same reference numerals are portions having the same functions as those denoted by the same reference numerals described in any of the drawings.
[0002]
[Prior art]
Two parallel first parallel members P in a structure 100 (hereinafter, referred to as a first conventional technique) of a structure 100A having a structure in which a seismic strength is increased, for example, a single-story wooden house as shown in FIG. For example, the members arranged in parallel such as the base members 2, 8, 8a, the beam members 1, 5, the beam members 6, 7 and the like, for example, perpendicular to these first parallel members P The two parallel second parallel members Q arranged, for example, the pillar members 3, 4, 9, 10, etc. are formed as frame members P • Q that form a square space U, and the A first diagonal point connecting member R that connects the diagonal points, for example, the diagonal points a1 and a2, for example, the bracing members 11, 13, and 15, and the first diagonal points a1 and a2. Are different second diagonal points, for example, the diagonal points b1 and b2 Second diagonal points connecting member S for connecting, for example, configuration in which to enhance the earthquake resistance by linking the bracing member 12, 14, 16 are well known.
[0003]
In the configuration of FIG. 8, only a portion that becomes a framework is illustrated, but it goes without saying that an inner wall, an outer wall, a ceiling, a floor, a roof, and the like are attached to the framework as necessary.
[0004]
Further, when the structure 100 is a structure 100B composed of a two-story wooden house as shown in FIG. 9 (hereinafter referred to as second prior art), the frame members P and Q, for example, the first parallel member, are used. Necessary diagonal points with respect to the rectangular space U formed by P and the second parallel member Q, for example, the first diagonal points a1 and a2 and the second diagonal points b1 and b2 Are connected by the same first diagonal point connecting member P and second diagonal point connecting member Q to increase the seismic strength, which is different from the structure 100 of FIG. Girder members 1a, 6, 7, 5a were used instead of the base member on the lower side of the first parallel member P of the frame members P, Q forming the rectangular space U in the second floor portion. It just has a configuration.
[0005]
8 and 9, only the portion that becomes the framework is illustrated, but it goes without saying that the inner wall, the outer wall, the ceiling, the floor, the roof, etc. are attached to the framework as necessary. .
[0006]
In the configuration in which the first diagonal point connecting member R and the second diagonal point connecting member S are fixed to the frame members P and Q forming such a rectangular space U, [Four Corner Fixing Configuration] in FIG. , The third prior art) and [four corners / center fixed configuration] (hereinafter referred to as the fourth prior art) are used.
[0007]
In [Four-corner fixed configuration] in FIG. 10, at each diagonal point, that is, at the first diagonal points a1 and a2 and the second diagonal points b1 and b2, for example, a strong plate such as an iron plate. Fixing members c1, c2, c3, and c4 formed in a suitable shape, for example, a quadrangle, as appropriate fixtures such as wood screws for the first parallel member P and the second parallel member Q A fixing tool d1 such as a screw nail or a coach screw is used to fix the first diagonal point connecting member R and the second diagonal point connecting member S using a fixing tool d2 using a bolt and nut. It is.
[0008]
In addition, in the [four corner / center fixed configuration] of FIG. 10, in addition to the above [four corner fixed configuration], the first diagonal point connecting member R and the second diagonal point connecting member S are opposed to each other. An appropriate fixture for fixing an intersecting portion (referred to as a cross-opposing portion in this specification) T through both the first diagonal point connecting member R and the second diagonal point connecting member S; For example, it is fixed with a fixture d3 using bolts and nuts.
[0009]
In addition, an appropriate material, for example, a filling e1 of the same material as the diagonal point connecting member R / S, for example, a rhombus plate material, is sandwiched in the gap between the crossing facing portions T, and the fixture e1 is also passed through the plate material. Let it stick.
[0010]
In the event of an earthquake, for example, the upper part of the rectangular space U in FIG. 10 swings left and right and deforms into a parallelogram with a leftward inclination or a parallelogram with a rightward inclination. -When a stress is applied such that one of the distances between a2 and the distance between the diagonal points b1 and b2 is extended, a stress is applied so that the other is shortened.
[0011]
Accordingly, when the [Four Corner Fixing Configuration] in FIG. 10 is viewed on the right side, in the steady state, the first diagonal point connecting member R and the second diagonal point connecting member are in the steady state as in FIG. Both S and S are in a parallel state, and the wall portions 21 and 22 forming the inner wall or the outer wall are fixed to the outside of both, but the first diagonal point connection member R and the second diagonal point connection Since the wall portions 21 and 22 are fixed to the member S by nailing at intervals, the first diagonal point connecting member R and the second diagonal point connecting member S are used as members to reinforce the member S. Does not act, and the wall portions 21 and 22 are weighted to the first diagonal point connecting member R and the second diagonal point connecting member S at the central portion of the space U having a square shape, that is, at the intersection facing portion T. Since it acts in the same manner as when the body is added, the walls 21 and 22 are respectively connected to the first diagonal point connecting member R and the second diagonal point. It has a vibration between the binding member S to a member such as Cassin.
[0012]
Here, when the upper part of the rectangular space U is shaken leftward due to the vibration, the stress in the direction (arrow f) for shortening the distance between the first diagonal points a1 and a2, that is, Since the compressive stress is applied, for example, as shown in [left-handed state] in FIG. 11, the first diagonal connecting member R is bent outwardly when resisting the compressive stress (arrow g). Since the bending stress is applied in the direction (arrow h) in which the distance between the diagonal points b1 and b2 extends, the second diagonal is applied. The point connecting member S receives a tensile stress that is pulled up and down.
[0013]
Further, when the upper part of the rectangular space U is shaken to the right due to the vibration, the stress in the direction (arrow f) for shortening the distance between the second diagonal points a1 and a2, that is, compression Since stress is applied, for example, as shown in [right-handed state] in FIG. 11, the first diagonal point connecting member R is bent in the direction of bending outward (arrow g) when resisting the compressive stress. Due to the bending stress, the second diagonal point begins to warp outward at the location of the cross-facing portion T and stress is applied in the direction in which the distance between the diagonal points b1 and b2 extends (arrow h). The connecting member S receives a tensile stress that is pulled up and down.
[0014]
In the vibration caused by the earthquake, the [left-handed state] and the [right-handed state] are alternately repeated, and therefore, one of the first diagonal point connecting member R and the second diagonal point connecting member S. It is well known that the weaker diagonal point connecting member breaks first, and then the remaining diagonal point connecting member breaks, which is weak in earthquake resistance.
[0015]
Therefore, a countermeasure using the [Four Corner / Center Fixed Configuration] in FIG. 10 is taken, but in this configuration, the [steady state], [left-handed state] and [right-handed state] in FIG. By fixing the portion, the state is changed to [steady state], [left-handed state], and [right-handed state] in FIG. 12, respectively. As a result, the effective cross-sectional area of the crossing facing portion T in the first diagonal point connecting member R and the second diagonal point connecting member S is dug for the through hole e2 and the washer d4. Since it is reduced by the amount of the defective portion D, and the weakness against breakage is promoted along with the weakening of the notch due to the through hole e2, the expected earthquake resistance cannot be obtained.
[0016]
Such seismic conditions are substantially the same even in the case of a steel structure, for example, a lightweight cellular concrete panel-clad steel structure, so the first diagonal connection member R or the second diagonal connection member for a steel structure. As the seismic member used for S, as shown in FIG. 13, a bracing member constituted by arranging a member having viscoelasticity therein, that is, a viscoelastic bracing member 300 (hereinafter referred to as fifth prior art). For example, using a product name “viscoelastic damper” of Showa Electric Cable Co., Ltd. has been attempted to obtain a structure with improved earthquake resistance.
[0017]
In the present invention, viscoelasticity means that a deformation force caused by a static stress acts with a viscosity that causes plastic deformation following the stress, and a dynamic force due to vibrations during an earthquake. For such energy, it has the property of acting with a viscosity that produces a speed-dependent damping effect and an elasticity that produces an opposing force due to elasticity, for example, non-vulcanized or semi-cured rubber It is well known that materials such as neoprene rubber and butyl rubber are materials having such viscoelasticity.
[0018]
In FIG. 13, the viscoelastic muscle member 300 includes a long tubular outer member 301 having a cross section of a “Japanese character” and one fixed end 302 provided at one end, and two pieces of an elongated plate-like body 303a. An inner member 305 formed in a tuning fork shape by providing the other fixed end 304 at a place where the ends of 303b are integrally connected.
[0019]
Then, the two pieces of plate-like bodies 303a and 303b of the inner member 305 are inserted into the upper and lower space portions of the “day-shaped” of the outer member 301, and the two pieces of plate-like bodies 303a and 303b and the “day-shaped” And a viscoelastic member 306 having viscoelasticity between the inner surface of the space.
[0020]
Therefore, if the fixed ends 302 and 304 are fixed at a required diagonal point, for example, at the diagonal points a1 and a2 or the diagonal points b1 and b2, the compression direction (arrow f) and the tension direction (arrow h) Since the viscoelasticity of the viscoelastic member 306 acts on the stress in each direction of the bending direction (g), the earthquake resistance is improved.
[0021]
[Problems to be solved by the invention]
The viscoelastic interstitial member 300 according to the configuration of the fifth prior art works effectively in the case of the structure 100 in which the steel frame of the frame is configured with heavy-weight steel frames, but the frame is configured with a wooden structure or a lightweight steel frame. In the case of the structure 100, for example, a wooden house or a light steel prefab house, the size and weight of the viscoelastic bracing member 300 itself is increased, and there is a disadvantage that a practical structure cannot be obtained from the price profit side. .
[0022]
For this reason, it is said that it is desired to provide a structure having seismic resistance due to viscoelasticity with a simple and inexpensive configuration that can be constructed in the field like the configurations of the third prior art and the fourth prior art. There are challenges.
[0023]
[Means for Solving the Problems]
In the present invention, the viscoelastic member as described above is directly or indirectly interposed in the intersection facing portion T between the first diagonal point connecting member R and the second diagonal point connecting member S. By mounting viscoelastic coupling means for coupling, the above-described problems are solved.
[0024]
In the configuration in which the viscoelastic member is directly interposed and connected, the viscoelastic member having viscoelasticity, itself, is directly interposed in the cross-facing portion T, and both sides of the viscoelastic member are bonded by, for example, adhesion. The first diagonal point connecting member R and the second diagonal point connecting member S are fixedly connected to each other. In this case, the liquid material before curing of the viscoelastic body may be injected and cured into the central portion of the flexible annular body 52 made of polyurethane or the like without using an adhesive.
[0025]
In addition, the above-described configuration in which they are indirectly interposed and connected is provided with metal fittings for fixing the first diagonal point connecting member R and the second diagonal point connecting member S, and the like. Between the first diagonal point connecting member R and the second pair by the viscoelastic member and the metal fitting, for example, by interposing a viscoelastic member and fixing both surfaces of the viscoelastic member by adhesion or the like. The crossing facing portion T with the corner point connecting member S is connected.
[0026]
Furthermore, by providing and providing a part by the above-mentioned configuration that is indirectly interposed and connected as an earthquake-resistant connection tool, it is possible to use an earthquake-resistant connection tool having viscoelasticity while performing a skeleton work at a construction site or the like. It is designed to perform seismic construction.
[0027]
[Action]
Therefore, according to the present invention, for example, as shown in FIG. 2, the cross-opposing portion T between the first diagonal point connecting member R and the second diagonal point connecting member S directly exhibits viscoelasticity. The cross-opposing portion T of the first diagonal point connecting member R and the second diagonal point connecting member S is connected to the seismic connecting tool 50X as shown in FIG. Are indirectly connected to each other via a viscoelastic member 50 having viscoelasticity, so that generation of a component force that bends outward even when subjected to stress in the compression direction (arrow f) is suppressed. Therefore, it is possible to obtain a structure with improved seismic strength.
[0028]
【Example】
1 to 7, an embodiment in which the present invention is applied to the configurations of the third prior art and the fourth prior art will be described. 1 to 7, the parts denoted by the same reference numerals as those in FIGS. 8 to 13 are parts having the same functions as the parts having the same reference numerals described in FIGS. 8 to 13. Moreover, the part shown with the same code | symbol in FIGS. 1-7 is a part which has the same function as the part of the same code | symbol demonstrated in either of FIGS.
[0029]
[First embodiment]
Hereinafter, the first embodiment will be described with reference to FIG. The difference between the first embodiment and the configuration of [Four-corner fixed configuration] of FIG. 10 is that the first diagonal point connecting member R and the second diagonal point connecting member S intersect with each other in the cross-facing portion T. This is a point in which a viscoelastic member 50 having viscoelasticity is directly interposed to connect the crossing facing portions T. That is, viscoelastic coupling means 50X that viscoelastically couples the first diagonal point coupling member R and the second diagonal point coupling member S is formed so that both diagonal point coupling members R and S cross each other. Mounted on the part T.
[0030]
The viscoelastic member 50 is a plate material made of a material such as, for example, a non-vulcanized or semi-vulcanized rubber material such as neoprene rubber or butyl rubber, and has a gap G1 (see FIG. 1 [ Side plate] is slightly larger in thickness, for example, about 1.3 times the thickness of the gap G1, and is slightly larger than the shape of the cross-facing portion T, for example, about 1.1 times larger. It is formed in a rhombus shape.
[0031]
And the structure to connect is the non-adhesive thin paper (not shown) on the outer surface of what coated the adhesive agent, for example, rubber-type adhesive agent (not shown) on both surfaces of the board | plate material which consists of the viscoelastic member 50 previously. ) For example, we provide a product with a thin paper with a coating of fluorine-based synthetic resin, ethylene-based synthetic resin, etc. applied to one side of the paper, and peel it off at the construction site to expose it. The adhesiveness of the adhesive surface is restored by applying an adhesive restoration agent such as petroleum benzine, cyclohexane, or normal hexane to the surface of the adhesive.
[0032]
Further, the surfaces facing each other as the cross-facing portion T between the first diagonal point connecting member R and the second diagonal point connecting member S were cleaned with a wooden hook as necessary. Later, a viscoelastic member 50 having viscoelasticity is bonded by applying a predetermined adhesive, for example, an adhesive similar to the above adhesive, and pressing the surface where the adhesiveness is restored. Alternatively, as in the case of the viscoelastic member 50, a non-adhesive thin paper is pasted on the outer surface coated with the adhesive in advance, and the adhesiveness of the surface of the adhesive is similarly increased during the bonding operation. It is designed to be revived and bonded.
[0033]
Further, if necessary, the cross-opposing portion T between the first diagonal point connecting member R and the second diagonal point connecting member S is temporarily fixed by nailing or the like, and after the adhesion is stabilized. Further, the work for removing the temporary fixing can be performed.
[0034]
In the configuration in which the cross-opposing portions T are viscoelastically connected according to the first embodiment, the viscoelastic member 50 having viscoelasticity is directly interposed and the [directly interposed configuration] in FIG. 1 and FIG. When the first diagonal point connecting member R and the second diagonal point connecting member S are made of a material having a relatively high rigidity, the [high rigidity type configuration] of FIG. As described above, the elasticity of the viscoelasticity exhibited by the viscoelastic member 50 acts to reduce the dynamic bending stress applied to the crossing facing portion T, thereby improving the earthquake resistance of the structure 100. Works.
[0035]
Further, in the case of a material having a relatively low rigidity, the elasticity of the viscoelasticity exhibited by the viscoelastic member 50 acts as shown in [Low rigidity type configuration] in FIG. By sufficiently suppressing the dynamic bending stress applied to the portion T and reducing the dynamic bending stress applied to the first diagonal point connecting member R and the second diagonal point connecting member S, the structure This acts to improve the earthquake resistance of the object 100.
[0036]
Furthermore, after the construction of the entire structure 100, since the stress due to long-term stress or drying shrinkage that occurs in each part of the framework acts as a static stress, the viscoelastic member 50 exhibits the viscosity. As the viscosity of elasticity acts, and with the passage of time, plastic deformation corresponding to the static stress occurs, so that the stress due to such strain is removed.
[0037]
[Second Embodiment]
Hereinafter, a second embodiment will be described with reference to [Indirect Interposing Type Configuration] in FIG. 1 and FIGS. The configuration of the second embodiment is different from that of the first embodiment described above in that the viscoelastic member 50 is indirectly connected to the viscoelastic member 50 via a predetermined metal fitting instead of the viscoelastic member 50 interposed directly. It is the point which comprised so that it might interpose.
[0038]
3 and 4, the mounting bracket 61 has a U-shaped cross section, and is substantially perpendicular to the non-opening portion X facing the one-side opening portion Y opened on one side of the U-shape. And a pair of facing portions Z facing each other. The pair of facing portions Z is provided with a pair of both-side opening portions YY that are coupled adjacent to each other and face each other substantially orthogonally to the one-side opening portion Y. One of the pair of mounting brackets 61 thus configured penetrates the pair of both-side opening portions YY so as to pass from the one-side opening portion Y between the pair of facing portions Z. One of the connecting members in the cross-opposing portion T of the diagonal point connecting members R and S can be fitted and fixed. On the other hand, in the same manner, The other connecting member in the intersection facing portion T of the diagonal point connecting members R and S can be fitted and fixed.
Each of the pair of mounting brackets 61 is combined with an opposing bracket 62 having a sliding contact surface 62A parallel to the non-opening portion X of the mounting bracket 61, and the non-opening portion X is in contact with the sliding contact surface 62A. For example, the swing metal fitting 65 is configured to be slidably attached to the sliding contact surface 62 </ b> A of the opposing metal fitting 62 by a flange 63 so as to be in sliding contact. In this case, the attachment here allows the mounting bracket 61 and the counter bracket 62 to swing relative to each other in the plane of the sliding contact surface 62A as indicated by an arrow B (FIG. 3). However, it may be rotatable about the collar 63.
[0039]
A plate member 51 made of a material having viscoelasticity, which will be described later, between opposite surfaces of the sliding contact surface 62A of the opposing hardware 62 of the pair of rocking hardware 65, with one pair of such rocking hardware 65 as one set, That is, the viscoelastic means 50 and 50X are configured by interposing the viscoelastic plate 51 indirectly.
In the above description, referring to [U-shaped / each part] in FIG. 3, as is clearer, each U-shaped part of the mounting bracket 61 has one opening when viewed from the direction of the U-shaped. The portion Y is referred to as “one-side opening portion Y”, and the two opening portions YY viewed from the side with respect to the U-shape are referred to as “a pair of both-side opening portions YY”.
[0040]
Then, each U-shaped opening portion Y of the pair of mounting hardware 61 is fitted into the crossing facing portion T of the first diagonal point connecting member R and the crossing facing portion T of the second diagonal point connecting member S. Then, without forming a through hole in the first diagonal point connecting member R and the second diagonal point connecting member S, two U-shaped parallel parts Z are connected to a predetermined fixture V, for example, Both opposing surfaces of the pair of opposing fittings 62 are fixed to the first diagonal point connecting member R and the second diagonal point connecting member S by wood screws, screw nails, coach screws, etc. By interposing the viscoelastic plate material between 62B, that is, the viscoelastic plate material 51, the crossing facing portion T of the first diagonal point connecting member R and the second diagonal point connecting member S are provided. The viscoelastic member 50 having viscoelasticity, i.e., the viscoelastic plate 51 is indirectly connected Those constituting the viscoelastic coupling member 50X which is adapted for coupling by instrumentation.
[0041]
Each portion constituting each swing metal piece 65 is formed by pressing a metal material, for example, a stainless steel plate having a thickness of about 1.5 to 2 mm, and the portion of the flange 63 is formed in a washer shape. The formed head portion and the round bar are welded to each other, and after the flange 63 is loosely fitted to the counter metal fitting 62, the end of the round bar is welded through the attachment metal fitting 61 so that the counter metal fitting 62 is attached to the metal fitting. It is also possible to configure so as to be able to swing with respect to 61.
[0042]
Further, a viscoelastic plate 51 having a circular outer shape is formed by disposing a flexible annular body 52 in contact with the outer circumference of the circle in order to prevent deformation in the radial direction of the circle. The viscoelastic plate 51 is formed by laminating, for example, a plate mainly made of the above-mentioned non-vulcanized or semi-vulcanized rubber material, and the flexible annular body 52 is made of a porous material. It is made of a synthetic resin material such as sponge-like polyurethane.
[0043]
The viscoelastic plate material 51 and the annular body 52 are integrated into a component pre-adhered in the same manner as the viscoelastic member 50 having the viscoelasticity in the first embodiment, and the swing metal fitting 65 is also used. Similarly, it may be provided as an anti-seismic connector 50X having an on-site assembly type structure that is provided as a part to which an adhesive is applied, and is assembled and assembled on site. As described above, the viscoelastic plate member 51 and the annular member 52 may be provided as the seismic coupler 50X by integrally bonding them between the opposing metal fittings 62 of the swing metal fittings 65 in advance.
[0044]
In the configuration according to the second embodiment, a viscoelastic plate 51 corresponding to the viscoelastic member 50 is indirectly interposed so that [indirectly interposed type configuration] in FIG. 1 and [connection portion / enlargement] in FIG. Therefore, the seismic action by viscoelasticity acts as shown in [High Rigidity Configuration] and [Low Rigidity Configuration] in FIG. Accordingly, the opposing metal fitting 62 and the viscoelastic plate material 51 are made larger than the area of the opposing portion in the cross opposing portion T, as compared with the case of [High rigidity type configuration] [Low rigidity type configuration] in FIG. Since the viscoelasticity corresponding to the magnitude | size can be obtained by comprising, the structure 100 which improved further earthquake resistance compared with the case of 1st Example will be obtained.
[0045]
[Third embodiment]
The third embodiment will be described below with reference to FIG. The configuration of the third embodiment is different from that of the second embodiment described above in that instead of the swinging metal fitting 65, a counter metal fitting 73 made of only a flat plate-like fixing metal 71 similar to the counter metal fitting 62 is arranged. This is the point that was configured.
[0046]
In FIG. 6, the fixing metal 71 is a metal plate, for example, a stainless steel plate having a thickness of about 1.5 to 2 mm, which is simply cut into a square and provided with mounting holes 72. The viscoelastic plate material 51 and the annular body 52 are exactly the same as those in the second embodiment.
[0047]
The mounting hole 72 is not limited to the first diagonal point even when the crossing angle between the first diagonal point connecting member R and the second diagonal point connecting member S at the crossing facing portion T changes variously. The connecting member R and the second diagonal point connecting member S can be fixed to the connecting member R and the second diagonal point connecting member S by an appropriate fixing tool (not shown) such as a wood screw, a screw nail, and a coach screw from the direction indicated by the arrow. It is arranged corresponding to the angle of.
[0048]
As in the case of the second embodiment, the on-site assembly type configuration in which the fixing bracket 71, the viscoelastic plate 51 and the annular body 52 are provided as separate parts, and the integrated type configuration in which these are provided in advance as an integral unit. These configurations are the same as those in the second embodiment. However, in the case of an integral configuration, the mounting holes 72 are naturally disposed on the outer periphery of the viscoelastic plate member 51 and the annular body 52 on the outer periphery of the fixing member 71 after being removed. is there.
[0049]
In the case of the configuration according to the third embodiment, the action of earthquake resistance by viscoelasticity acts in the same way as the [high rigidity type configuration] and [low rigidity type configuration] in FIG. As a result, a structure 100 having earthquake resistance in exactly the same manner is obtained.
[0050]
[Fourth embodiment]
The fourth embodiment will be described below with reference to FIG. The configuration of the fourth embodiment is different from that of the second embodiment described above in that it is configured to dispose the opposing metal fitting 75 using only the mounting bracket 61 instead of the swing metal fitting 65.
[0051]
In FIG. 7, a mounting bracket 61 is exactly the same as the mounting bracket 61 in the second embodiment. The viscoelastic plate member 51 and the annular member 52 have the same structure as that in the second embodiment described above, and are sized so that the outer diameter falls within the opposing area of the cross-facing portion T. Is directly adhered to the flat surface 61A of the non-opening portion X of the U-shaped mounting bracket 61.
[0052]
As in the case of the second embodiment, the U-shaped mounting bracket 61, the viscoelastic plate member 51 and the annular body 52 are provided as separate parts, and these are assembled in advance. An integrated configuration is possible, and these configurations are configured in the same manner as in the second embodiment.
[0053]
Therefore, in the case of the configuration according to the fourth embodiment, the action of earthquake resistance by viscoelasticity is the same as that of the [high-rigidity type configuration] and [low-rigidity type configuration] in FIG. Since the area contributing to the viscoelasticity is reduced by the circular shape of the annular body 52, the structure 100 having an earthquake resistance slightly lower than the earthquake resistance in the first embodiment is obtained.
[0054]
