The present invention relates to a unit building.

 In unit buildings, as described in JP-A-8-302823 (page 3, Fig. 2) (Patent Document 1), pin joining is performed based on the plinth of a building unit made of a frame structure in which columns and beams are welded. Doing.

Moreover, in order to strengthen the frame rigidity of the building unit which consists of the ramen structure comprised by combining the column and the beam as described in Unexamined-Japanese-Patent No. 8-199689 (patent document 2), the ceiling beam and the floor There is a trapezoidal reinforcing frame between beams.

In addition, as described in Japanese Utility Model Publication No. 51-45847 (Patent Document 3), in a unit building, a plate is placed between the upper floor beams and the lower floor ceiling beams between the upper and lower building units. Some of these beams are fastened by bolts to prevent floor bending.

In addition, as described in Japanese Patent No. 3330409 (Patent Document 4), in the unit building, the bottom beams of the upper building unit and the ceiling beams of the lower building unit are interposed between these webs in the center thereof. Combined to improve the rigidity of the floor beams and ceiling beams.

Moreover, as a joining structure of a unit building, as described in Unexamined-Japanese-Patent No. 6-49911 (patent document 5), there exists a thing which joins mutually side-by-side cylinders with the clearance gap between adjacent building units. The joining structure of patent document 5 has the 1st nut member provided in the one side pipe column, the 2nd nut member arrange | positioned facing this 1st nut member, and provided in the other side pipe column, and both nuts in the clearance gap of both pipe columns. It consists of a screw member which is screwed to a member, and the spacer of the round pipe shape which covered the screw member between the clearance gap of both pipe columns.

Moreover, as a unit building which makes it possible to form a large continuous space which omitted a pillar, as described in patent 3260266 (patent document 6), the pillar omission corner part set in each of adjacent building units is mutually abutted at a pillar omission junction. Arrange the reinforcement beam from the ceiling beam side of the building unit on one side of the column omission junction to the ceiling beam side of the building unit on the other side, join one end of the reinforcement beam around the column of the one building unit, and Some parts are joined to the periphery of the pillar of the other building unit.

In the prior art of patent document 1, since the rigidity of a beam is small, even if the cross section of a column is strengthened, a plinth will rotate about a foundation and a horizontal rigidity of a building will not become high. Therefore, it is necessary to add an intermediate pillar to the wall surface or to add a horizontal brace to the ceiling surface, which causes a limitation in design and cost of these buildings.

Moreover, in patent document 2, a trapezoidal reinforcement frame is provided between the ceiling beam and the floor beam of a building unit, and a reinforcement frame becomes a complicated member which previously joined the inclined material to the both ends of a horizontal member, and the horizontal member of a reinforcement frame is a building Overlapping on the ceiling beam of the unit.

Further, in Patent Documents 3 and 4, only the upper and lower beams (bottom beams and ceiling beams) are simply joined to each other at their intermediate portions, and the strength of the two beams is strengthened to improve the strength to the vertical load, There is no reasonable consideration of enhancing the stiffness of the building unit as a frame to improve its strength against horizontal loads.

Moreover, the joint structure of patent document 5 has the following problems.

(1) It is necessary to weld the first nut member at the factory to the pipe column of the building unit on one side of the adjacent building unit in advance, and attach the screw member to the first nut member in a protruding state. Productivity is bad, and the handleability in the transportation storage step of a building unit is bad.

(2) At the construction site, the installation of the building unit is poor because the building unit cannot be installed close to the building unit unless the screw member of one building unit is covered with a spacer.

(3) A spanner for rotationally driving the second nut member screwed to the screw member is inserted into the gap between the two tube columns of the building unit adjacent to each other and further toward the second nut member in a window provided in the spacer. And the operability of the nut member is bad.

Moreover, the prior art of patent document 6 has the following problem.

(1) The length of the reinforcement beam from one building unit side to the other building unit when attaching a reinforcement beam to a ceiling beam intersected at the corner of the column omission in the same plane including the column omission joint of both building units. It becomes a long beam, and the difficulty of material management and construction is large.

(2) We reinforce reinforcement beam outside of ceiling beam and need extra space for reinforcement beam around perimeter of both building units. If other building units are to be installed at the side edges of both building units, it is necessary to form a gap large enough to place reinforcement beams between the other building units.

An object of the present invention is to improve the horizontal rigidity of a unit building.

Another object of the present invention is to improve the vertical rigidity of a unit building.

Another object of the present invention is to simply reinforce the reinforcement decrease caused by the omission of a pillar in a unit building forming a large continuous space in which the pillar is omitted.

The present invention is a unit building formed by fixing a building unit made of a ramen structure formed by strong bonding of columns and beams to a foundation, wherein the plinth of the building unit is rigidly bonded to the foundation, and between the plinth of the building unit and the middle of the ceiling beam, Alternatively, the inclined material is installed between the head of the head and the middle of the floor beam.

In addition, the present invention is a unit building formed by fixing a building unit in which a column, a floor beam, and a ceiling beam are bonded to a foundation, wherein the pillars of the building unit are rigidly bonded to the foundation, and the pillars are defined in each of a plurality of adjacent building units. The abbreviated corner portions are disposed to face each other at the column omitted joints, and the ceiling beams intersected with the pillar omitted corner portions in the same plane including the column omitted joints of the adjacent building units are used as joint ceiling beams. It is to be made by joining the joint ceiling beams facing each other in the column omitted joint.

The horizontal rigidity of the building unit 20 can be improved. It is not necessary to reinforce the cross section of the column 21 to increase the horizontal rigidity of the building unit 20, and there is no need to add an intermediate column or a horizontal brace, thereby increasing the design freedom of the building unit 20 and reducing the cost. have.

(Old method II: up and down beam joint structure) (FIGS. 6-9)

The old method II is provided between the ceiling beam 23 of the lowest building unit 20 and the floor beam 32 of the upper building unit 30, and / or the ceiling beam 33 and the upper building unit of the upper building unit 30 ( 40 is applied between the bottom beams 42 (FIGS. 1 and 2).

The two building units 30 are joined by joining both ends of the two beams 23 and 32 so that they are hardly shifted by the steel joints R1 and R2, and the middle parts are joined so that they are hardly shifted by the steel joint R3. When the two beams 23 and 32 deform in S-shape by the horizontal load P acting on the pillar 31, the phase difference between the both ends and the middle of the two beams 23 and 32 is suppressed (FIG. 9A). ). As a result, the frame strength of the building units 20 and 30 can be enlarged to improve the yield strength against the horizontal load.

The frame stiffness of the building units 20, 30 according to the present invention is about 1.3 times that of the normal model to which the present invention is not applied (FIG. 9B).

In the old method II, the structure which joins the floor beam 32 of the upper building unit 30 and the ceiling beam 23 of the upper building unit 20 so that it hardly shift | deviates is the web (w) of these floor beams 32. FIG. And plate 50 along web (w) of ceiling beam (23) or flange (f) of these bottom beams (32) and plate (50) along flange (f) of ceiling beam (23). It can be carried out.

In addition, the gable direction plate 72 of the hole forming spacer 70 is formed between the sidewalls 21A and 21A of the sidewalls of the side-by-side tube columns 21 and 21 of the building units 20 and 20 adjacent to each other in the purlin direction. The bolt insertion holes 61A of the both tube columns 21 and 21 are inserted into the gaps 61 provided in the gap and inserted through the bolt mounting operation holes 61B formed in the side wall 21B of the one side tube column 21. 61A) and through the bolt insertion hole 72A of the gable direction plate 72 provided in the gap between the side walls 21A, 21A of the both side cylinders 21, 21, and pass through the side wall of the other side cylinder 21.

It can be joined so as to be almost not shifted. When the two beams 23 and 32 are curvedly deformed under the action of the vertical load, the phase difference between both ends of the two beams 23 and 32 is suppressed. Accordingly, the two beams 23 and 32 exhibit a cross-sectional performance that is greater than the sum of the cross-sectional performances of the respective beams 23 and 32, thereby increasing the rigidity and improving the yield strength to the vertical load. In addition, when the two beams 23 and 32 deform in S-shape due to the horizontal load acting on the pillar 31 of one side building unit 30, the phase difference between both ends and the middle of the two beams 23 and 32 is changed. Is suppressed. As a result, the frame strengths of the building units 20 and 30 can be increased to improve the bearing capacity against the horizontal load. In the unit building 1, the old method II and the old method III are applied together, and the horizontal rigidity and the vertical rigidity of the unit building 1 can be strengthened together.

(Old Method IV: Slope Reinforcing Structure) (Figs. 17 to 19)

The old method IV is 31F of the pillar 31 of the upper building unit 30 (40 degree | times) between the plinth 21F of the pillar 21 of the lowest building unit 20, and the middle part of the ceiling beam 23, and 31F. ) And between the middle part of the ceiling beam 33 or between the pit 31H of the column 31 of the upper building unit 30 (40 degrees equal) and the middle part of the floor beam 32 (FIG. 1). , FIG. 2).

17A shows the inclination material 101 provided between the circumferential angle 21F of the pillar 21 of the lowest-floor building unit 20, and the intermediate part of the ceiling beam 23. As shown in FIG. The inclined material 101 is pin-joined to each of the circumferential angle 21F of the pillar 21 and the intermediate part of the ceiling beam 23 (even in a steel joint).

FIG. 17B shows the inclined material 102 provided between the circumferential angle 31F of the pillar 31 of the upper floor building unit 30 and the middle portion of the ceiling beam 33. The inclined material 102 is pin-bonded (even in steel joint) to each of the circumferential angle 31F of the pillar 31 and the intermediate part of the ceiling beam 33. As shown in FIG. In addition, since the upper floor building unit 30 has the floor beam 32, the above-mentioned inclined material 102 is provided between the pier 31H of the column 31 and the intermediate part of the floor beam 32. It may be.

According to the old method IV, in the unit building 1, one corner of the frame of the ramen structure is provided by providing the inclined material 101 between the plinth 21F of the lowest-floor building unit 20 and the middle part of the ceiling beam 23. A right triangle formed by a portion of the phosphor pillar 21 and the ceiling beam 23 together with the inclined material 101 is referred to as an invariant body (an invariant truss). Accordingly, the apparent length L2 of the ceiling beam 23 in the building unit 20 (deformation length L2 excluding the invariant truss portion L1 from the total length L of the ceiling beam 23). ) Can be shortened to enhance the frame rigidity, thereby improving the yield strength against the horizontal load (P) (FIG. 18).

In addition, the inclined material 102 is located between the plinth 31F of the upper-floor building unit 30 (the same as 40 degrees) and the middle of the ceiling beam 33 (or between the plinth 31H and the bottom beam 32). ), A right triangle formed by a part of the pillar 31 and the ceiling beam 33, which is one corner of the frame of the ramen structure, together with the inclined material 102 is used as an invariant body (invariable truss). Accordingly, the apparent length L2 of the ceiling beam 33 in the building unit 30 (deformation length L2 excluding the invariant truss portion L1 from the total length L of the ceiling beam 33). By shortening), the frame stiffness can be strengthened to improve the yield strength against the horizontal load (P).

By the simple structure which only adds the inclination materials 101 and 102, saving the frame of the pillar 21 and the beam 23 of the ramen structure, and the frame of the pillar 31 and the beams 32 and 33, Since the above-described invariant body (unchanged truss) can be formed, the above-mentioned frame stiffness can be easily realized.

By pin-joining the inclined members 101 and 102 to each of the pillars 21 and 31 and the beams 23 and 33 (32), the above-described invariant body (invariable truss) is easily formed in one corner of the frame of the ramen structure. It is possible to simplify the installation work of the inclined materials (101, 102).                     

Since it is frame rigidity reinforcement only by the inclination materials 101 and 102, since it does not interfere with formation of opening in the ramen structure of building units 20 and 30, etc., comparatively large opening can be formed.

The frame stiffness of the building units 20 and 30 (40 degree | times same) by this invention becomes 1.3 to 2.0 times with respect to the normal model to which this invention is not applied. In the building unit 20 and the building unit 30 (the same as 40 degrees), the inclined materials 101 and 102 are used as the ceiling beam 23 of the building unit 20 and the ceiling beam 33 of the building unit 30. When the length L1 of the invariable truss portion is set to 450 mm and 900 mm, the allowable horizontal load Pa of the building units 20 and 30 is inclined as shown in FIG. With respect to the allowable horizontal load Pa (1300 kg, 900 kg) of the normal model not using the ashes 101 and 102, the building unit 20 is expanded to 1550 kg and 1700 kg, and in the building unit 30 It expands to 1200 kg and 1400 kg.

In addition, as shown in FIG. 19, in the lowest-floor building unit 20, left and right inclined materials 101 and 101 between the pleats 21F of the left and right pillars 21, and each of the left and right middle parts of the ceiling beam 23. As shown in FIG. ) May be installed. In addition, also in the upper-floor building unit 30 (40 degree | times same), the left and right intermediate | middle of the plinth 31F (or head pit 31H) of the left and right pillars 31 and the ceiling beam 33 (or floor beam 32). The left and right inclined members 102 and 102 may be provided between each of the sections. According to this, the invariant truss formed by joining the left and right inclined materials 101, 101, 102, 102 to the ceiling beam 23 of the lowest floor building unit 20 and the ceiling beam 33 of the upper floor building unit 30 is formed. Even if the length L1 of the portion is short, for example, 450 mm, the allowable horizontal load Pa of the building units 20, 30 can be greatly enlarged, such as 2050 kg or 1800 kg.                     

20-22 is the specific mounting example of the inclination material 101 (similar to 102 degree | time) in the old method IV. The building unit 20 (30, 40 degrees equally) is an example with the floor beams 22, and the reinforcing frame 25 including the inclined material 101 between the floor beams 22 and the ceiling beams 23 is provided. I'm putting it.

The reinforcement frame 25 has the reinforcement pillar 26 and the interstitial pillar 27 attached to the pillar 21, and the inclined material 101 to the mounting plate 26A extended horizontally from the lower end part of the reinforcement pillar 26. The lower end of the inclination member is joined to each other by welding or the like, and the upper end of the inclined member 101 is joined to the upper end side of the interstitial pillar 27 by welding or the like. 27, across the joint beam 28 in the middle of the lower side, across the joint beam 29 in the upper middle of the inclined material 101 and the upper middle of the reinforcing column (26) do.

The reinforcement frame 25 is bolted to the joint piece 22J which joined the mounting plate 26A which comprises the lower end part of the reinforcement pillar 26 and the inclination material 101 to the pleats 21F of the pillar 21. Then, the mounting plate 26B extending horizontally from the upper end of the reinforcing column 26 is bolted to the joint piece 23J joined to the head 21H of the column 21. At this time, an L-shaped bottom beam reinforcing piece 103 is welded to the upper flange of the bottom beam 22 captured by the joint piece 22J and the inner surface of the web, and the mounting plate 26A of the inclined material 101 is welded. Is seated on the joint piece 22J, and joined by the bottom beam reinforcing piece 103, the bottom beam 22, the joint piece 22J, and the bolt 104 and nut 104A passing through the mounting plate 26A. do.

The reinforcement frame 25 bolts the lower end of the inter-column 27 to the upper flange of the bottom beam 22, and bolts the upper end of the inter-column 27 to the lower flange of the ceiling beam 23. At this time, the ceiling beam reinforcement piece 105 of a C-shaped cross section is welded between the upper and lower flanges of the ceiling beam 23 to which the upper end of the interstitial column 27 is bolted together.

In addition, in this embodiment, "joining so that it does not shift substantially" means "joining so that a joining part may maintain a rectangle", "joining so that the overlapping part of an upper and lower beams may not shift", etc., but including a strong joint Weaker junctions are also included. In addition, joining of the edge part of a beam includes joining in the vicinity of an end part.

(Old method V: column omitted reinforcement structure) (FIGS. 23-28)

The old method V is applied at the column omitted corner of the building unit 20 (same for 30 and 40 degrees) (FIGS. 1 and 2).

(Example 1) (FIG. 23, FIG. 24)

The unit building 1A of FIG. 23 is a part of the unit building 1 of FIG. 1, FIG. 2, and is constructed by adjacently arranging the plurality of building units 20 from side to side, and four pillars constituting a part thereof. The omission is to form a wide continuous space in which the pillars are omitted by the building unit 120.

As shown in FIG. 3, the building unit 20 has four rectangular steel beam columns 21, four steel bottom beams 22, and four steel ceiling beams 23 in a box shape. It is a joined skeleton structure. The building unit 20 connects the floor beams 22 that intersect with each other at the four corners to the lower end of the column 21 by the joint pieces 22J, and the ceiling beams 23 that cross each other connect the joint pieces ( It is comprised by joining to the upper end part of the pillar 22 by 23J).                     

The column abbreviation building unit 120 omits one pillar 21 of the four pillars 21 of the standard building unit 20 as shown in FIG. 24. The pillar omission building unit 120 connects the floor beams 22 that intersect with each other at three corner portions other than the pillar omission corners with respect to the floor beams 22 at the lower end of the column 21 by the joint pieces 22J. The bottom beams 22 intersecting with each other at the column omitted corner are joined to each other by the joint pieces 22K. The pillar omission building unit 120 uses the ceiling beam 23 along the gable direction as the joint ceiling beam 121 among the ceiling beams 23 arranged to intersect the pillar omission corner with respect to the ceiling beam 23. The ceiling beams 23 are used as standard ceiling beams 23. The upper ends of the standard ceiling beams 23 and the pillars 21 are joined by joint pieces 23J, and the joint ceiling beams 121 and the pillars 21 are joined. The upper end of the joint is joined by a joint piece 23K, and the joint ceiling beam 121 and the ceiling beam 23 are joined by a joint piece 23L.

The pillar omission building unit 120 makes the cross-sectional strength of the joint ceiling beam 121 higher than the cross-sectional strength of the other standard ceiling beams 23. The joint ceiling beam 121 is made of C-shaped steel with a lip attached thereto, and the end plate 122 is joined to an end portion at the side of the pillar omitted corner, and the joint piece 23L welded to the end portion is an end plate ( A part of the side part of the joint piece 23L is cut out like the notch 123 along the periphery of the end plate 122 so that 122 may not be covered. In the column omitted building unit 120, the dimension of the surface position of the end plate 122 which makes the column 21 joined by the joint piece 23K in the longitudinal direction of the joint ceiling beam 121 the reference position. Precision is secured.                     

The pillar abbreviation building unit 120 makes attachment and detachment of the temporary pillar 124 free to a pillar omission corner part. The temporary column 124 is detachably attached to the joint piece 22K of the bottom beam 22 and the joint piece 23L of the ceiling beams 23 and 121 described above by detachable means such as bolts and pins.

In the unit building 1A, as shown in FIG. 23A, the pillar omitted corner portions defined in each of the four pillar omitted building units 120 (120A to 120D) in a part of the lower floor portion are disposed to face each other at the pillar omitted junction 2. do.

Ceiling beams 23 intersected between their column omitted building units 120A and the column omitted building units 120B in the same plane that includes both of the column omitted junctions 2 in the column omitted corners thereof. Denotes the above-described joint ceiling beam 121 (FIG. 24). In this way, the end plates 122 of the joint ceiling beams 121 opposed by the column omitted joints 2 of both building units 120A and 120B are parallel to each other through a constant gap. Thus, a spacer 110 of a plate thickness selected to adapt to the gap is inserted between the end plates 122 of the mating ceiling beams 121 above or to the side of the gap. In this embodiment, two spacers 110 are inserted in the upper and lower ends of the end plate 122. Then, the end plates 122 of the opposing ceiling beams 121 are strongly joined together with the high-strength bolt 111 (not shown) together with the spacer 110. The high-strength bolt 111 is inserted through the bolt insertion hole 122A of the counter end plate 122 and the bolt insertion hole 110A of the spacer 110, and the nut 112 is fastened to the insertion end. In this embodiment, two high-strength bolts 111 on the left and right sides are used for one spacer 110. For this reason, the joints are rigidly joined in the longitudinal direction of the joint ceiling beam 121 and also in the direction orthogonal to them in the horizontal direction, so that the steel joints are almost completely rigid. As the high-strength bolt 111, a torso type, a hexagonal bolt type, or the like can be adopted.

Even between the column omitted building unit 120C and the column omitted building unit 120D corresponding to each other, the same as that between the building unit 120A and the building unit 120B described above, The end plates 122 are strongly bonded together with the high-strength bolts 111 together with the spacers 110.

When the end plates 122 of the corresponding joint ceiling beam 121 are joined between the building unit 120A and the building unit 120B, the building unit 120C, and the building unit 120D corresponding to each other, Temporary columns 124 are installed at the column omitted corners of the building unit 120. Then, after the end plates 122 of the mating ceiling beams 121 to be joined to each other, the temporary pillar 124 is separated.

According to this embodiment, the following effects are obtained.

(a) By joining the joint ceiling beams 121 crossing each column omission corner in each of the building units 120 adjacent to each other, these joint ceiling beams 121 are continuous over both building units 120. It is integrated like a long beam. Therefore, since the unit building 1A which omitted the pillar can be reinforced without using the long beam separate from the building unit 120, manageability and workability of a material are good.

(b) Since the unit building 1A can be reinforced by the joint ceiling 121 itself, which is part of the ceiling beam 23 constituting the building unit 120, a separate reinforcement around the building unit 120 is provided. There is no need to attach the member. Even when installing the other building unit 20 on the side of the building unit 120, it is not necessary to make the same thing as the installation clearance for reinforcement members between the other building units 20. As shown in FIG.

(c) The joint ceiling beam 121, which reinforces the unit building 1A by crossing the column omitted joint of the unit building 1A, increases the cross-sectional strength to the extent that the drop in strength caused by the column omission can be compensated for, and the other By setting the cross-sectional strength of the ceiling beams 23 to a standard level, the cross-sectional strengths of all the ceiling beams 23 of the building unit 120 can be sufficiently necessary to achieve economical structural strength.

(d) By jointing the end plates 122 of the joint ceiling beam 121 of the building unit 120 adjacent to each other with the high-strength bolt 111 through the spacer 110, the joint ceiling beams 121 are simplified. Since it can join together, the dimensional precision of 1A of unit buildings can be improved.

(e) The temporary column 124 installed in the corner omission corner of the building unit 120 is the site of the joint ceiling beam 121 after the site installation through the factory manufacturing step and the transportation storage step of the building unit 120. It is not separated until the connection is completed. Therefore, since the strength of the building unit 120 at the construction stage can be sufficiently secured without lowering the strength of the building unit 120 at the time of connection of the joint ceiling beam 121, workability is good.

(Example 2) (FIG. 25)

The unit building 1B of FIG. 25 forms a space without a large wall with the upper building unit 30 on which the two lower building units 120 constituting part thereof are mounted.

The pillar omission building unit 120 used in Example 2 differs from the pillar omission building unit 120 of Example 1 in that the two pillars 21 of the standard building unit 20 are adjacent to each other in the purlin direction. Two pillars 21 are omitted, and the two ceiling beams 23 along the gable direction are used as the joint ceiling beams 121, and the ceiling beams 23 in the purlin direction intersecting the joint ceiling beams 121 are temporarily made. The beam 125 is used to allow the temporary column 125 to be detachably attached to the free end of the joint ceiling 121 by attaching and detaching means such as bolts and pins so that the temporary pillar 125 can be removed.

In the unit building 1B, as shown in FIG. 25A, each of the two pillar omitted corner portions fixed to each of the two pillar omitted building units 120 (120A, 120B) in a part of the lower floor portion is the pillar omitted junction 2 , 3) to face each other.

As shown in FIG. 25B, between the pillar omitted building unit 120A and the pillar omitted building unit 120B, the end plates 122 of the opposing joint ceiling 121 are joined to each other. After that, the temporary column 124 is removed to remove the temporary beam 125 (simply detached).

And the building unit 30 which comprises an upper floor part is mounted in the upper part of the column abbreviation building unit 120. As shown in FIG. Since the upper building unit 30 forms a wallless space on the upper part of the lower building unit 120, the floor beam 22 of the portion corresponding to the temporary beam 125 of the lower building unit 120 is installed from the beginning. It is either not done or is ablated after mounting.                     

In the unit building 1B, a space without a large wall from the lower building unit 120 to the upper building unit 30 can be formed while securing the structural strength by the joint ceiling beam 121.
