Description

  The present invention relates to a corrugated steel plate mounting structure in which corrugated steel plates are attached to peripheral members constituting a frame, and a building having the corrugated steel plate mounting structure.

As a corrugated steel sheet obtained by processing a steel sheet into a corrugated shape, as shown in Patent Document 1, a corrugated steel shear wall arranged in the frame surface of a frame with the direction of the corrugated crease in the horizontal direction has been proposed. This corrugated steel shear wall does not bear vertical force because it expands and contracts like an accordion in the vertical direction, but it can resist seismic loads and has excellent deformation performance while ensuring shear rigidity and shear strength. Have.
When the upper and lower horizontal members constituting the frame are moved relative to each other by an external force such as an earthquake load, a shearing force acts on the corrugated steel sheet, and the corrugated steel sheet undergoes shear deformation. Thereby, a corrugated steel plate resists external force, and exhibits an earthquake resistance effect. In addition, by designing the corrugated steel sheet to yield with respect to external force, vibration energy is absorbed by the hysteresis energy of the steel sheet, and a damping effect can be exhibited. Thus, in order to apply an external force as a shearing force to the corrugated steel sheet, the four circumferences of the corrugated steel sheet are joined to a horizontal member, a column, or the like constituting the frame.

  For example, in Patent Document 1, studs are erected on the outer periphery of a corrugated steel sheet at a predetermined interval, and the corrugated steel sheet is attached to a frame by embedding the stud along the longitudinal direction of a reinforced concrete beam and column. However, if the stud is embedded along the longitudinal direction of the beam or column, the mounting operation becomes complicated. For steel frames, it is conceivable to weld corrugated steel sheets along the longitudinal direction of the beams and columns. However, this welding work takes time.

On the other hand, as shown in FIGS. 20A and 20B, the corrugated steel earthquake resistant wall of Patent Document 2 has a corrugated steel plate 210 that is positioned above and below the frame 206 composed of reinforced concrete columns 202 and beams 204. Only the beam 204 is joined. That is, the corrugated steel sheet 210 is joined to the upper and lower beams 204 by embedding studs erected on the outer periphery of the corrugated steel sheet 210 in the upper and lower beams 204. As described above, the corrugated steel earthquake resistant wall of Patent Document 2 does not join the corrugated steel plate 210 to the left and right columns 202, but embeds the studs 208 at predetermined intervals along the longitudinal direction of the beam 204, which makes the joining work complicated. ing.

  In view of the above facts, an object of the present invention is to provide a corrugated steel sheet mounting structure that reduces the labor of mounting corrugated steel sheets, and a building having the corrugated steel sheet mounting structure.

  The corrugated steel plate mounting structure according to claim 1 is a corrugated steel plate mounting structure in which the corrugated steel plate is attached to the peripheral member constituting the frame. The corrugated steel plate mounting structure is a corner portion formed by intersecting the peripheral members, at least diagonally. A fixing member fixed to two corner portions, an attachment portion provided on an outer periphery of the corrugated steel plate, and the fixing member capable of transmitting shearing force acting on the corrugated steel plate to a joint portion of the frame And a joining means for joining the attachment portion.

  According to the above configuration, the fixing members are fixed to the corner portions formed by intersecting the peripheral members and at least two corner portions on the diagonal. On the other hand, the attachment part is provided in the outer peripheral part of a corrugated steel plate. The attachment portion and the fixing member are joined to each other so that shearing force acting on the corrugated steel sheet can be transmitted to the joint portion of the frame by joining means. Thereby, a corrugated steel plate is attached to a frame.

  In this way, by consolidating the joints between the frame and the corrugated steel plate at the corners of the frame, it is possible to reduce the labor of the joining work. On the other hand, the shearing force acting on the corrugated steel sheet is transmitted from the mounting portion to the joint portion of the frame via the fixing member. That is, the shearing force of the corrugated steel plate acts on the joint of the frame. However, since the joint portion of the frame is higher in rigidity and strength than other parts of the frame, reinforcement of the frame can be reduced. Therefore, it is possible to reduce the trouble of mounting the corrugated steel sheet while reducing the reinforcement of the frame.

  The corrugated steel plate mounting structure according to claim 2 is the corrugated steel plate mounting structure according to claim 1, wherein the peripheral member is a column and a beam or a column and a slab.

That is, a corrugated steel plate is attached to a frame composed of columns and beams, or a frame composed of columns and slabs, and the corrugated steel plate is used as a seismic wall. Therefore, when constructing a seismic wall using a corrugated steel plate, it is possible to reduce the labor of attaching the corrugated steel plate.

  The corrugated steel plate mounting structure according to claim 3 is the corrugated steel plate mounting structure according to claim 1, wherein the peripheral member is a beam.

  According to said structure, a corrugated steel plate is attached to the frame which consists of a beam, for example, a floor surface or a roof surface. When corrugated steel is attached to the floor, it plays the role of transmitting the inertial force generated in the building to the seismic elements. In addition, by designing the corrugated steel sheet to yield with respect to external force, the vibration energy is absorbed by the hysteresis loop and functions as a damping member. Therefore, it is possible to construct a floor structure that is lighter and more excellent in seismic performance than conventional concrete slabs.

  Moreover, when a corrugated steel plate is attached to the roof surface, the corrugated steel plate functions as a brace that increases rigidity and plays a role as a roof material that prevents wind and rain. Conventionally, when two members of a roof material such as a roof deck and a diagonal material such as a brace are attached to the roof surface, it is only necessary to attach a corrugated steel sheet, so that the workability is improved.

  The building of Claim 4 has the corrugated steel plate attachment structure of any one of Claims 1-3.

  According to said structure, the corrugated steel plate attachment structure is used for the building. Therefore, it is possible to construct a building with improved workability and a shortened construction period.

As described above, by consolidating the joint portion between the frame 20 and the corrugated steel plate 22 at the corner portions 31A to 31D (see FIG. 1) of the frame 20, labor for attaching the corrugated steel plate 22 is reduced.

  On the other hand, when a horizontal force such as an earthquake load acts on the frame 20, a shearing force acts on the corrugated steel plate 22 to cause shear deformation. Thereby, the corrugated steel plate 22 resists the horizontal force and exhibits an earthquake resistance effect. In addition, by designing the corrugated steel plate 22 to yield with respect to the horizontal force, vibration energy is absorbed by the hysteresis energy of the steel plate, and a damping effect can be exhibited.

As shown in FIGS. 8 (A) and 8 (B), the fixing member 46 may be constructed by welding the plate 63 to the top of the leading plate 56 and standing the stud 38. Thus, by increasing the number of studs 38, the stress transmission between the frame 20 and the corrugated steel sheet 48 becomes good.

  As shown in FIG. 7A, the H-shaped steel 52 provided on the outer periphery of the corrugated steel plate 48 is formed by integrally forming a web portion 60 and upper and lower flange portions 62 and 64. A flange portion 62 is partially cut off at the end of the H-shaped steel 52, and as shown in FIG. 7B, a web portion 60 and a flange portion 62 are formed in an L-shaped cross section. A fixing plate 58 is superimposed on the web portion 60 through the notch.

  7B, through holes 58A and 60A through which the pin portion 40A of the shear pin 40 passes are formed in the fixing plate 58 and the web portion 60 of the H-shaped steel 52, respectively. The fixed plate 58 and the H-shaped steel 52 are joined.

  Next, operations and effects of the corrugated steel plate mounting structure according to the second embodiment will be described.

  As shown in FIG. 6, the H-shaped steel 52 provided on the outer periphery of the corrugated steel plate 48 is fixed to the corner members 31 </ b> A to 31 </ b> D of the frame 20, that is, the fixing members 46 fixed to both ends of the beam 16 by the shear pin 40. The corrugated steel plate 48 is attached to the frame 20 by joining. In the first embodiment, as shown in FIG. 1, the fixing member 32 is fixed across the column 12 and the beam 16, but in this embodiment, as shown in FIG. 9, at the ends of the upper and lower beams 16. Since only the fixing member 46 is fixed, the labor of fixing the fixing member 46 can be reduced. Further, when the beam 16 is made of a precast concrete structure, by fixing the fixing member 46 to the beam 16 in a factory or the like, installation work at the site can be omitted, so that workability is improved.

  Further, when a horizontal force such as an earthquake load acts on the frame 20, the shearing force acting on the corrugated steel plate 48 is transmitted from the H-shaped steel 52 via the shear pin 40 and the fixing member 46 (FIG. 7). (See (A)). At this time, although the shearing force borne by the corrugated steel plate 48 is concentrated on both ends of the beam 16, both ends of the beam 16 are compared with other parts of the frame 20, as with the joint portion 21. Designed with high rigidity and high strength. Therefore, by fixing the fixing member 46 to the corner portions 31A to 31D of the frame 20 as in the present embodiment, the reinforcement of the frame 20 is reduced with respect to the concentrated force (shearing force) transmitted from the corrugated steel plate 48. be able to.

Components having the same configurations as those in the first and second embodiments are denoted by the same reference numerals and will be appropriately omitted.

  As shown in FIG. 9 (plan view), a pillar 64 made of a square steel pipe, beams 66 and 68 made of H-shaped steel projecting from the pillar 64, and an H-shaped steel laid between the two beams 66. Two frames 72A and 72B are constituted by the small beam 70. The column 64 and the beams 66 and 88 are fastened at the joint 65 by a gusset plate, bolts, or the like (not shown). Further, the beam 66 and the small beam 70 are tightly coupled to each other at the joint 71 by a gusset plate, a bolt, or the like (not shown).

  Corrugated steel plates 22 are attached to the construction surfaces (floor surfaces) of the frames 72A and 72B, respectively. Steel fixing plates 80 and 82 (fixing members) are fixed to the corner portions 76A to 76D of the frame 72A, respectively. The corner portions 76B and 76D will be described as an example. In the corner portion 76B, the web portion 66A of the beam 66 and the web portion 68A of the beam 68 are straddled, and the fixing plate 80 is welded along the outer peripheral surface of the column. In the corner portion 76D, the fixing plate 82 is welded across the web portion 66A of the beam 66 and the web portion 70A of the small beam 70. The fixing plates 80 and 82 are also welded to the corner portions 76A and 76C by the same method.

The fixing plate 80, 82 is joined to the mounting plate 30 of the corrugated steel plate 22 by the shear pin 40, and the corrugated steel plate 22 is attached to the construction surfaces (floor surfaces) of the frames 72A, 72B.
Note that fixing plates 80 and 82 are respectively fixed to the corner portions 78A to 78D of the frame 72B by the same method as the corner portions 76A to 76D of the frame 72A, and the mounting plate 30 of the corrugated steel plate 22 is fixed by the shear pins 40. It is joined.

  Next, operations and effects of the corrugated steel plate mounting structure according to the third embodiment will be described.

  As shown in FIG. 9, the mounting plate 30 provided on the outer periphery of the corrugated steel plate 22 is joined to the fixing plates 80 and 82 fixed to the corner portions 76 </ b> A to 76 </ b> D of the frame 72 </ b> A by the shear pin 40. A corrugated steel plate 22 is attached to the plate. Further, the corrugated steel plate 22 is attached to the frame 72B by joining the mounting plates 30 provided on the outer periphery of the corrugated steel plate 22 to the fixing plates 80 and 82 fixed to the corner portions 78A to 78D of the frame 72B. As described above, by consolidating the joint portions of the frames 72A and 72B and the corrugated steel plate 22 to the corner portions 76A to 76D of the frame 72A or the corner portions 78A to 78D of the frame 72B, the labor for attaching the corrugated steel plate 22 is reduced. Is done.

  Here, a general floor structure 82 is shown in FIG. 10, and the load distribution of a horizontal force such as an earthquake load acting on the floor structure 82 (floor surface) will be described. FIG. 10 is a plan view showing the floor structure 82.

  As shown in FIG. 10, four frames 88A, 88B, 88C, and 88D are configured by a steel-structured column 84 and a beam 86 protruding from the column 84. Concrete slabs 90 are laid on the construction surfaces (floor surfaces) of the frames 88A to 88D. Further, a steel brace 92 is installed on the frame 88A and the frame 88D.

  When a horizontal force F such as an earthquake load acts on the floor structure 82, the horizontal force F is concentrated on the steel brace 92 having high rigidity and strength through the columns 84, the beams 86 and the slab 90. At this time, the load distribution of the shearing force generated in the slab 90 increases from the center of the floor structure 82 toward the steel brace 92 as indicated by an arrow X.

  As described above, the slab 90 serves as a transmission path for the shearing force, but the shearing force is mainly absorbed by the steel brace 92. In this embodiment, instead of the slab 90 of the floor structure 82, the corrugated steel plate 22 is attached to the frame structure (floor surface) serving as a shearing force transmission path, thereby providing a vibration energy absorbing function. In other words, in FIG. 9, when a horizontal force such as an earthquake load acts on the frames 72 </ b> A and 72 </ b> B, a shearing force acts on the corrugated steel plate 22 to cause shear deformation. Thereby, the corrugated steel plate 22 resists the horizontal force and exhibits an earthquake resistance effect. In addition, by designing the corrugated steel plate 22 to yield with respect to the horizontal force, vibration energy is absorbed by the hysteresis energy of the steel plate, and a damping effect can be exhibited. Therefore, compared with the general floor structure 82 described above, a floor structure that is lightweight and has excellent seismic performance can be constructed.

  Further, the shearing force acting on the corrugated steel plate 22 is transmitted from the mounting plate 30 to the joint portions 65 and 71 of the frames 72A and 72B via the shear pin 40 and the fixing plates 80 and 82 (fixing members). However, the joints 65 and 71 are joints between the column 64 and the beams 66 and 68, or the beam 66 and the small beam 79, and are reinforced by a gusset plate or the like. Higher rigidity and strength than Therefore, it is possible to reduce the labor of attachment work while reducing the reinforcement of the frames 72A and 72B.

  Next, a corrugated steel plate mounting structure according to the fourth embodiment will be described. In the fourth embodiment, the corrugated steel plate 22 is attached to the roof structure 94 instead of the first embodiment. In addition, the thing of the same structure as 1st-3rd embodiment attaches | subjects the same code | symbol, and abbreviate | omits suitably and demonstrates.

  As shown in FIG. 11 (A), the roof structure 94 is composed of a ridge wood 96 made of H-shaped steel, and suspended wood 98 and suspended wood 100 made of H-shaped steel projecting from the ridge wood 96 to the left and right. The hanging wood 98 and the hanging wood 100 are joined to the building wood 96 at predetermined intervals along the longitudinal direction of the building wood 96. Between the adjacent suspended lumbers 98 and between the adjacent suspended lumbers 100, crosspieces 102 and 104 made of H-shaped steel are respectively spanned at predetermined intervals. When this roof structure 94 is viewed from the direction of the arrow Y, a frame 106 is constituted by the hanging wood 98 and the crosspiece 102 as shown in FIG. The suspended wood 98 and the crosspiece wood 102 are fastened together at the joint 112 by a gusset plate, bolts or the like (not shown).

  Fixed plates 110 are fixed to the corner portions 108 </ b> A to 108 </ b> D of the frame 106. The corner portions 108A and 108C will be described as an example. The fixing plate 110 is welded across the web portion 98A of the hanging wood 98 and the web portion 102A of the crosspiece wood 102. The mounting plate 30 of the corrugated steel plate 22 is joined to these fixed plates 110 by the shear pins 40, and the corrugated steel plate 22 is attached to the construction surface (roof surface) of the frame 106.

  Next, operations and effects of the corrugated steel plate mounting structure according to the fourth embodiment will be described.

  As shown in FIG. 11B, the mounting plate 30 provided on the outer periphery of the corrugated steel plate 22 is joined to the fixed plate 110 fixed to the corners 108A to 108D of the frame 106 by the shear pin 40, A corrugated steel plate 22 is attached to 106. As described above, by consolidating the joint portion between the frame 106 and the corrugated steel plate 22 at the corner portions 108 </ b> A to 108 </ b> D of the frame 106, labor for attaching the corrugated steel plate 22 is reduced.

  When a horizontal force such as an earthquake load acts on the frame 106, a shearing force acts on the corrugated steel plate 22, and the corrugated steel plate 22 undergoes shear deformation. Thereby, the corrugated steel plate 22 resists a horizontal force and exhibits an earthquake resistance effect. In addition, by designing the corrugated steel plate 22 to yield with respect to the horizontal force, vibration energy is absorbed by the hysteresis energy of the steel plate, and a damping effect can be exhibited. As described above, when the corrugated steel plate 22 is attached to the construction surface (roof surface) of the frame 106 formed on the roof structure 94, the corrugated steel plate 22 functions as a seismic element or a vibration control element and also serves as a roof material that prevents wind and rain. Fulfill. Thus, in a general roof structure, it is necessary to attach two members, a roof material such as a roof deck and a diagonal material such as a vibration control brace. In this embodiment, the corrugated steel plate 22 functions as a roof deck and a brace. Therefore, it is only necessary to attach the corrugated steel plate 22 to the frame 106, and the workability is improved.

  Further, the shearing force acting on the corrugated steel plate 22 is transmitted from the mounting plate 30 to the joint portion 112 of the frame 106 via the shearing pin 40 and the fixing plate 110 (fixing member). The joint portion 112 is a joint portion between the hanging wood 98 and the crosspiece wood 102 and is reinforced by a gusset plate or the like, and therefore has higher rigidity and strength than the portion of the other frame 106. Therefore, it is possible to reduce the labor of attachment work while reducing the reinforcement of the frame 106.

  In all the embodiments described above, the fixing plate as the fixing member is fixed to all the corner portions of the frame. However, the present invention is not limited to this. The fixing plate should just be fixed to the corner part of at least 2 places on the diagonal among four corner parts. The first embodiment will be described as an example. As shown in FIG. 12, among the four corner portions 31A to 31D of the frame 20, the fixing plate 36 is fixed only to the two corner portions 31B and 31D. You may do it. In this case, the attachment plate 30 provided on the outer periphery of the corrugated steel plate 22 may be provided according to the fixed plate 36. In this way, by attaching the corrugated steel plate 22 to at least two corner portions 31B and 31D positioned diagonally, the corrugated steel plate 22 resists the horizontal force acting on the frame 20, and functions as an earthquake resistant element. At the same time, it functions as a vibration control element by design.

From the viewpoint of stress transmission and vibration energy absorption performance, as shown in FIG. 13, among the four corner portions 31 </ b> A to 31 </ b> D of the frame 20, the fixing plate 36 is attached to the three corner portions 31 </ b> B, 31 </ b> C, 31 </ b> D. It is preferable to fix. In this case, compared with the configuration of FIG. 12, not only the stress transmission path between the frame 20 and the corrugated steel plate 22 is increased, but also the rotational motion of the corrugated steel plate 22 about the straight line connecting the corner portion 31B and the corner portion 31D. Is suppressed. Furthermore, as shown in FIG. 1, it is preferable to fix the fixed plate 3 to the four corner portions 31A, 31B, 31C, 31D and attach the corrugated steel plate 22.
For reference, the fixing plate is not fixed to the two corners positioned diagonally, but the fixing plate 36 is fixed to the two corners 31C and 31D of the frame 20, as shown in FIG. It is also possible to attach the corrugated steel plate 22 to the frame 20 by fixing the fixing plate 58 (see FIG. 7A) near the center of the upper beam 16.

  In all the above embodiments, when the columns and beams constituting the frame are made of precast concrete, the beams or columns and the fixing member may be integrally formed in advance. In the first embodiment, the case where the columns 12 and the beams 16 are made of precast concrete will be described as an example. The fixing member 32 can be fixed to the beams 16 as shown in FIG. In this configuration, a leading plate 114 is embedded in the upper end portion of the column 12. An embedded anchor nut 116 and a stud 118 as a shearing force transmission element are alternately welded to the leading plate 114. Further, from the upper end surface of the column 12, a column main reinforcing bar 12 </ b> A in which the column 12 is arranged protrudes.

  On the other hand, the beam 16 is formed by integrating a joint portion 120 placed on the upper end portion of the column 12 and beam portions 122 and 124 projecting left and right from the joint portion 120. A sheath tube 126 is embedded in the joint portion 120 so that the column main reinforcement 12A of the column 12 can be inserted. The fixing member 32 is fixed to the base of the beam portion 124 by embedding a stud 38 (see FIG. 3) inside the beam portion 124. A bolt hole 130 through which the bolt 128 passes is formed in the angle 34 of the fixing member 32. The bolt hole 130 is formed so as to coincide with the anchor nut 116 when the joint 120 is placed on the upper end of the column 12.

  At the site, the column main reinforcement 12A is inserted into the sheath tube 126, and the joint portion 120 of the beam 16 is placed on the upper end of the column 12 so that the leading plate 114 and the angle 34 of the fixing member 32 face each other. Then, the bolt 128 is screwed into the anchor nut 116 through the bolt hole 130 and tightened to fix the fixing member 32 to the column 12. In this way, by integrally forming the beam 16 and the fixing member 32 at a factory or the like, it is possible to reduce the burden of construction work on site. The column 12 and the joint 120 are integrated by filling the sheath tube 126 with a hardening material (not shown) such as grout, and together with the upper end of the column 12 and the base of the beam portion 124, Form corners. That is, the upper end portion of the column 12 and the base of the beam portion 124 are included in the corner portion of the frame.

  Next, the case where columns and beams are constructed of steel will be described. As shown in FIG. 16, a column 134 and a beam 136 made of H-shaped steel are rigidly joined at a joint portion 137 where the column 134 and the beam 136 intersect to form a frame 138. A fixing plate 140 (fixing member) is welded across the column 134 and the beam 136 at the corner portion 139A of the frame 138. As described above, the fixing plate 140 can be fixed to the column 134 and the beam 136 by welding or the like to the steel frame 138. The fixing method is not limited to welding, and may be joined with a bolt, a shear pin or the like via a gusset plate or the like.

  Further, in all the above embodiments, the H-shaped steel is joined to the outer periphery of the corrugated steel plate, but as shown in FIG. 16, the steel plate 142 is welded along the left and right end portions of the corrugated steel plate 22, and the upper and lower end portions are welded. The steel plate 144 may be welded along. In this case, end plates 142A and 144A are welded to the end portions of the steel plates 142 and 144, respectively, and these end plates 142A and 144A are joined at substantially right angles. The mounting plate 30 is welded so as to span between these end plates 142A, 144A. At this time, it is preferable to increase the rigidity of the mounting plate 30 by welding steel stiffening plates 146 and 148 between the steel plate 142 and the end plate 144A and between the steel plate 144 and the end plate 142A. .

  Further, in all the above embodiments, the material and the number of the fixing members may be designed according to the required rigidity and strength. For example, as shown in FIG. 17, even when two fixing plates 36 and 37 are welded to the angle 34, the bonding strength between the fixing member 32 and the mounting plate 30 provided on the outer periphery of the corrugated steel plate 22 is ensured. good. In this case, the mounting plate 30 is inserted between the fixing plates 36 and 37 (arrow A), and the fixing member 32 and the mounting plate 30 are joined. The fixing plate 37 is provided with a through-hole through which the pin portion 40A (see FIG. 3B) of the shear pin 40 passes in the same manner as the fixing plate 36. Thus, the stress transmission between the corrugated steel plate 22 and the frame 20 is improved by sandwiching and attaching the mounting plate 30 between the two fixing plates 36 and 37.

  Furthermore, the corrugated steel plate mounting structure of the present invention can be applied to a frame composed of columns and slabs. As shown in FIG. 18, a fragment of a lower part of a frame 154 composed of a reinforced concrete column 150 and a reinforced concrete slab 152 is shown. The slab 152 is supported by a reinforced concrete beam 156 protruding from the column 150.

  A fixing member 32 is fixed to the corner portion 155 </ b> A of the frame 154. A mounting plate 30 provided on the outer periphery of the corrugated steel plate 22 is joined to the fixing plate 36 of the fixing member 32 by a shear pin 40. In the frame 154, a portion where the column 150 and the slab 152 intersect becomes a joint portion 158.

  Moreover, in all the said embodiment, although the shear pin 40 was used as a joining means, it is not restricted to this. What is necessary is just to be able to transmit the shear force which a corrugated steel plate bears to the joint part of a frame, for example, you may join with a volt | bolt, a nut, etc. Furthermore, a high strength volt | bolt etc. can be used.
