Description

  The present invention relates to an edge reinforcement fixing structure of a strength element corrugated steel plate that reinforces an edge portion of a corrugated steel sheet arranged as a strength element in a load bearing wall panel and fixes it to a panel frame.

  Conventionally, as a load-bearing wall panel, a corrugated steel plate serving as a load-bearing element is arranged in the panel, and this is fixed to a panel frame. Conventionally, most of the corrugated steel plate fixing structure is a dispersion type. That is, in order to stop a corrugated steel sheet, which is a thin plate, using a screw such as a tapping screw or a bolt, there are many cases where it depends not on the strength of the screw or the bolt itself but on the bearing pressure due to the thickness of the plate. Therefore, many small screws or bolts are dispersed and fixed.

Corrugated steel sheet is a superior material as a load-bearing element of a load-bearing wall panel because it exhibits high yield strength even with a thin plate thickness. However, in order to fix the plate so that the plate thickness is very thin and the function as a load bearing element can be exerted, it is fixed by a distributed type using a large number of small screws or bolts as described above.
However, the manufacturing standards of screws and bolts are fixed, and even if the smallest commercially available screws or bolts are used to disperse and fix as many places as possible, sufficient fixing strength cannot often be obtained. The panel frame is made of a linear member such as a shape steel, and the corrugated steel sheet has crests and troughs of waves. When the corrugated steel plate is fixed to the flat panel frame surface, it can be usually fixed only at the troughs. For this reason, even in the case of fixing in a distributed type, it must be fixed in a limited space. For this reason, when trying to fix with many screws and bolts, a sufficient fixing space may not be secured.
In addition, if the structure is fixed using a large number of screws and bolts, there are many places where the fixing work is performed, so that a large burden is imposed on manufacturing or construction, which causes an increase in cost.
Although it is possible to fix the corrugated steel sheet by welding, since the corrugated steel sheet is thin, a sufficient welding range such as a welding leg length cannot be obtained, and sufficient strength for fixing the load bearing element is obtained. It cannot be secured.

  The object of the present invention is to increase the strength of a fixing portion of a corrugated steel sheet fixed by welding or the like, such as screws, without requiring the addition of a reinforcing member, etc. It is another object of the present invention to provide an edge reinforcing and fixing structure of a load bearing element corrugated steel sheet that can increase the fixing strength and rigidity required for fixing the load bearing element within a fixed range.

The basic structure of the edge reinforcing and fixing structure of the load bearing element corrugated steel sheet of the present invention is to reinforce the edge along the direction perpendicular to the ridge line direction of the wavy portion in the corrugated steel sheet arranged as the load bearing element in the load bearing wall panel. Strength-proof corrugated steel plate edge reinforcement fixing structure to be fixed to the panel frame of the wall panel,
In the corrugated portion of the edge of the corrugated steel plate, a plurality of overlapping reinforcing portions are provided by overlapping overlapping pieces formed by plastic processing of a part of the corrugated steel plate, and the overlapping reinforcing portion is fixed to the panel frame. It is characterized by that. The corrugated steel plate is fixed to the panel frame by, for example, a shaft-like fixing tool such as a screw or a bolt that penetrates the overlapping reinforcing portion.
The “plastic processing” refers to processing such as bending or crushing.

According to this configuration, the corrugated steel plate frame frame is provided with a plurality of overlapping reinforcing portions in which overlapping pieces formed by plastic processing of a part of the corrugated steel plate are provided in the corrugated portion of the edge of the corrugated steel plate. The thickness of the fixing edge is increased to 2 to 3 times the plate thickness. For this reason, when fixing with a shaft-like fixing tool such as a screw, it is possible to use a large-diameter fixing tool that is efficient for fixing. Stiffness can be increased. As a result, it is possible to secure the strength and rigidity of fixing the corrugated steel sheet necessary as a load bearing element. When fixing by welding, the weld leg length can be increased by increasing the thickness of the portion to be fixed by welding, and the fixing strength and rigidity can be increased.
In addition, since the overlap reinforcing portion is a portion in which overlapping pieces formed by plastic processing of a part of the corrugated steel plate are overlapped, unlike a case where another reinforcing member such as a reinforcing plate is additionally stacked, the overlap reinforcing portion is formed from a thin plate. It is possible to increase the fixing strength and rigidity by skillfully utilizing the corrugated steel sheet itself. By these, the burden concerning manufacture and construction of a bearing wall can also be reduced.

In this basic configuration , the corrugated steel sheet may have a rectangular cross section, for example. The corrugated steel sheet having a rectangular cross section is excellent as a load bearing element, and the rectangular corrugated shape allows easy and effective processing to provide overlapping pieces by plastic working of the corrugated steel sheet.

In the basic configuration , the edge reinforcing and fixing structure of the strength element corrugated steel sheet according to the present invention has any one of the following configurations for the overlapping piece of the overlapping reinforcing portion .
For example, a notch along the edge is made in the wavy portion at a position separated from the edge of the corrugated steel plate by the width of the overlapping piece in the ridge line direction, and the edge side portion is stretched on both sides with respect to the notch of the wavy portion. The overlapping piece of the overlap reinforcing portion may be configured by a double folded portion generated on the wave valley portion by flattening so as to protrude.
In the case of this configuration, the entire corrugated portion of the corrugated steel sheet becomes the overlapping piece, and the corrugated steel sheet can be used without waste to improve strength and rigidity.

In addition, the top of the wavy mountain portion is cut from the edge of the corrugated steel plate to the position separated by the width in the ridgeline direction of the overlapping piece, and the left portion of the wavy mountain portion from which the top has been cut is left at the location. The overlapping piece of the overlap reinforcing portion may be formed of a bent piece obtained by providing a cut and bending a standing piece that becomes a left uncut portion of the wave crest portion generated by the cut so as to overlap the wave valley portion.
In the case of this configuration, since the overlapping pieces are formed by bending, the processing for obtaining the overlapping reinforcing portion can be easily performed as compared with the crushing processing.

Further, it is a folded piece formed by cutting off the wavy portion to a place away from the edge of the corrugated steel sheet, and turning back a tongue piece formed of a wave valley portion remaining between the cut wavy portions, and the overlapping piece of the overlapping reinforcing portion is It may be configured.
Also in this configuration, since the overlapping pieces are formed by bending, the processing for obtaining the overlapping reinforcing portion can be easily performed as compared with the crushing processing. Moreover, in this structure, since the overlap reinforcement part does not become the shape which protruded, and an overlap reinforcement part is located between the adjacent wave crest parts, the intensity | strength of the corrugated steel plate as a strength element becomes high.

The edge reinforcement fixing structure of the load bearing element corrugated steel sheet according to the present invention reinforces the edge portion along the direction perpendicular to the ridge line direction of the wavy mountain portion in the corrugated steel sheet arranged as the load bearing element in the load bearing wall panel. A plurality of strength reinforcement element corrugated steel plate edge reinforcement fixing structure to be fixed to a panel frame, wherein a plurality of overlapping pieces formed by plastic working of a part of the corrugated steel plate are overlapped with the corrugated portion of the edge of the corrugated steel plate. Corrugated steel plate fixed by fixing means such as screws or welding, etc. to have a basic configuration of providing an overlap reinforcement portion of layers and fixing the overlap reinforcement portion to the panel frame. Increase the strength of the location without the need for additional reinforcing members, and increase the strength and rigidity required to secure the load-bearing elements with a limited number of fasteners and a limited fixing range. Can.

  A first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, the edge reinforcement fixing structure of the load-bearing element corrugated steel plate is a structure in which the edge portion 7 </ b> A in the corrugated steel plate 7 arranged as the load-bearing element in the load-bearing wall panel 1 is reinforced and fixed to the panel frame 2. In this example, a corrugated steel plate 7 is fixed to a horizontal frame member 6 constituting the panel frame 2. The edge portion 7 </ b> A is an edge portion in a direction orthogonal to the ridge line direction A of the wavy portion 7 a of the corrugated steel sheet 7. The corrugated steel sheet 7 is a corrugated steel sheet in which corrugated mountain portions 7a and corrugated valley portions 7b having a rectangular cross section are alternately arranged as shown in FIG. FIG. 4 shows a state in which the corrugated steel plate 7 is attached to the panel frame 1.

  1, in this embodiment, a double overlapping piece 7c, as shown in FIG. 1C, is formed on the corrugated portion 7b of the edge portion 7A of the corrugated steel plate 7 by plastic processing of a part of the corrugated steel plate 7. 7d is formed, and the triple overlapping reinforcing portion 10 is provided with the original wave valley portion 7b. The overlap reinforcing portion 10 is fixed to the structural frame material 6 of the panel frame 2 by a shaft-like fixing tool 11 such as a tapping screw passing through the overlap reinforcing portion 10. The number of fixing points by the fixing tool 11 for one overlap reinforcing portion 10 is, for example, one or two to three. The fixing tool 11 may be a bolt. In that case, a bolt insertion hole (not shown) is provided in the overlap reinforcing portion 10 and the lateral frame member 6.

  Here, the overlapping pieces 7c and 7d of the overlapping reinforcing portion 10 are processed and provided as follows. 1A, the edge of the corrugated steel plate 7 showing the shape of the material is separated from the edge of the corrugated portion 7a as shown in FIG. Make a cut 12 along the section 7A. As shown in FIGS. 2 (B) and 2 (C), the crushing process is flattened so that the portion of the wave mountain portion 7a on the edge side of the notch 12 projects to the left and right sides. Thus, overlapping pieces 7c and 7d are formed as double folded portions generated on the wave valley portion 7b. The triple overlapping reinforcing portion 10 is formed by the overlapping portion between the overlapping pieces 7c and 7d and the original wave valley portion 7b. This crushing process is performed by a press machine such as a press brake (not shown).

  According to the edge reinforcing and fixing structure of the load bearing element corrugated steel plate having the above-described configuration, the overlapping pieces 7c and 7d formed by plastic working of a part of the corrugated steel plate 7 are formed on the corrugated portion 7b of the edge portion 7A of the corrugated steel plate 7. In order to provide a plurality of stacked overlapping reinforcing portions 10 and fix the overlapping reinforcing portions 10 to the panel frame 2, the thickness of the edge portion 7A fixed to the panel frame 2 of the corrugated steel plate 7 is increased to three times the plate thickness. . Therefore, when fixing with a fixing tool 11 such as a screw, a large-diameter fixing tool that is efficient in fixing can be used, and fixing strength and rigidity can be achieved as centralized fixing with a small number of fixing tools 11 used. Can be increased. Thereby, the fixed strength and rigidity of the corrugated steel sheet 7 necessary as a load bearing element can be ensured.

In addition, since the overlap reinforcing portion 10 is a portion where the overlapping pieces 7b and 7c formed by plastic processing of a part of the corrugated steel plate 7 are overlapped, another reinforcing member such as a reinforcing plate is additionally stacked. Unlike the above, the corrugated steel plate 7 itself made of a thin plate can be skillfully used to increase the fixing strength and rigidity. By these, the burden concerning manufacture and construction of the bearing wall 1 can also be reduced.
In particular, in this embodiment, the overlap reinforcing portion 10 is formed by crushing the corrugated portion 7a of the corrugated steel plate 7 so as to protrude on both sides as described above, thereby overlapping the overlapping pieces 7c in the double folded state. 7d is formed, the entire length range of the wavy portion 7a of the corrugated steel sheet 7 becomes the overlapping pieces 7c and 7d, and the corrugated steel sheet 7 is used without waste to improve strength and rigidity. Available.

  6 and 6 show another embodiment of the present invention. In this embodiment, the overlapping reinforcing portion 10 is formed of overlapping pieces 7e as follows. From the edge of the corrugated steel plate 7 to the place separated by the width in the ridge line direction of the overlapping piece 7e, the flat top part of the wave mountain part 7a is cut out as shown in FIG. 5B, and the top part is cut off at the above part. The notch 13 is provided in the uncut portion of the wavy portion 7a. As shown in FIGS. 6 (C) and 6 (C), the standing piece that is the uncut portion of the wave crest portion 7a generated by the cut 13 is bent so as to overlap the wave valley portion 7b to form the overlapping piece 7e.

  In the case of this embodiment, since the overlapping piece 7e is provided by a bending process, the process of obtaining the overlapping reinforcing portion 10 can be easily performed as compared with the crushing process of the above embodiment. Other configurations and effects in this embodiment are the same as those in the first embodiment described above with reference to FIGS.

  FIG. 7 shows still another embodiment of the present invention. In this embodiment, the overlapping reinforcing portion 10 is formed by overlapping pieces 7f as follows. From the edge of the corrugated steel plate 7 to the location separated by the distance of the overlapping piece 7f, the wave crest portion 7a is cut out as shown in FIG. The tongue piece composed of the wave valley portion 7b remaining between the cut wave mountain portions 7a is folded back to form the overlapping piece 7f.

  Also in this configuration, since the overlapping piece 7f is formed by bending, processing for obtaining the overlapping reinforcing portion 10 can be easily performed compared to crushing processing. In the case of this configuration, the overlapping reinforcing portion 10 does not have a shape protruding in the wavy ridge line direction A from the wavy portion 7a of the corrugated steel sheet 7, and the overlapping reinforcing portion 10 is positioned between the adjacent wavy mountain portions 7a and 7a. Will do. For this reason, the strength of the corrugated steel sheet 7 as a strength element is increased. Other configurations and effects in this embodiment are the same as those in the first embodiment described above with reference to FIGS.

  Next, a structural example of the entire load bearing wall panel 1 to which the edge reinforcing and fixing structure of the load bearing element corrugated steel sheet of the above embodiment is applied will be described with reference to FIGS. You may apply the edge part reinforcement fixing structure of any said embodiment. This load-bearing wall panel 1 divides a panel frame 2 assembled in a rectangular shape into a plurality of partition layers a and b arranged vertically, with a plurality of horizontal frame members 6 serving as intermediate rails as boundaries, respectively. The corrugated steel plate 7 is provided as a load-bearing element in the layer a, and the diagonal member 8 is provided as a load-bearing element in the other partition layer b. The partition layer b provided with the diagonal material 8 is provided with a deformation absorbing device 9 that absorbs deformation of the partition layer b. In the example of the figure, it is equally divided into four partition layers, the diagonal material 8 is provided in the upper and lower partition layers b, and the corrugated steel plate 7 is provided in the middle two partition layers a.

  The panel frame 2 includes left and right vertical frame members 3 and 3, upper and lower horizontal frame members 4 and 5 joined between upper and lower ends of the left and right vertical frame members 3 and 3, and the left and right vertical frame members 3 and 3, respectively. And a horizontal frame member 6 serving as an intermediate beam joined between the frame members 3 and 3. Three horizontal frame members 6 are provided at equal intervals.

  In addition, although this load-bearing wall panel 1 is comprised as wall panels, such as an outer wall panel, it may be comprised as a wall used as a part of a frame construction method building. Further, the vertical frame member 3 may be a member that becomes a pillar of a building, or may be a member that is provided separately from the pillar and provided along the pillar in a panel combined use frame construction method or the like. The pillar may be a pillar built in a wall.

  Shaped steel is used for the left and right vertical frame members 3 and 3, and square pipes (also called square steel pipes) are used in the illustrated example. For the upper and lower horizontal frame members 4 and 5, a section steel having a narrower cross section than the vertical frame member 3, for example, a square pipe, is used and joined so as to be aligned with the indoor side surface of the vertical frame member 3. In FIG. 8, the same shape steel as the horizontal frame members 4 and 5 at the upper and lower ends, for example, a square pipe, is used for the horizontal frame member 6 serving as an intermediate rail. In addition to this, a shape steel obtained by joining two grooved steels back to back may be used for the horizontal frame member 6 serving as an intermediate rail. In addition, all the shape steels used in the embodiments of this specification are lightweight shape steels. The vertical frame member 3 and the horizontal frame members 4, 5, 6 are joined, for example, by joining the end surfaces of the horizontal frame members 4, 5, 6 to the end surface of the vertical frame member 3.

  As described above with reference to FIG. 3, the corrugated steel sheet 7 serving as the load-bearing element of the partition layer a is a corrugated steel sheet having a corrugated cross section in which the wave crest portions 7 a and the wave trough portions 7 b extending in one direction are alternately arranged. The partition layer a is stretched so as to extend in the vertical direction, that is, the extending direction of the wave crest portion 7a and the wave valley portion 7b is the vertical direction. In this example, the corrugated steel plate 7 uses a deck plate, and has a rectangular or trapezoidal cross section in which the top of the wavy portion 7a serving as a wavy mountain and the bottom of the wavy portion 7b serving as a wavy valley are flat portions. The upper and lower ends of the corrugated steel plate 7 are fixed to the horizontal frame members 4, 5, 6 with fixing tools 11 such as screws. For fixing the corrugated steel sheet 7 to the horizontal frame members 4, 5, 6, the edge reinforcement fixing structure of the load bearing element corrugated steel sheet in any of the above embodiments is applied. In addition, the corrugated steel plate 7 of each partition layer a may be individually manufactured, or one corrugated plate may be cut.

The corrugated width, height and angle of the corrugated steel sheet 7 must be strictly maintained in order to ensure the damping function, but the edge strength is increased as described above, so that the corrugated shape Can be maintained, and its damping function can be secured.
The corrugated steel sheet 7 serving as the load-bearing element has no slip property with respect to the in-plane shear force because the corrugated portion 7a of the wave is distorted in a direction intersecting the ridge line direction when an internal shear force is applied. Stable energy absorption is possible. Therefore, a history closer to the spindle type is shown.

  In FIG. 8, diagonal members 8 serving as load-bearing elements of the partition layer b are made of square pipes or other shape steels, and are provided on each partition layer b so as to incline in opposite directions and have one end approaching each other. ing. In the example of FIG. 8, the two diagonal members 8 of the partition layer b at the upper end are joined to the upper lateral frame member 4 via the deformation absorbing device 9, with the upper ends being close to each other. . The lower ends of the two diagonal members 8 are the spreading side ends of the two diagonal members 8 and are joined to the horizontal frame member 6 serving as an intermediate rail. The two diagonal members 8 of the partition layer b at the lower end are joined to the horizontal frame member 5 at the lower end via the deformation absorbing device 9 with the lower ends approaching each other. The upper ends of these two diagonal members 8 are the spreading side ends of the two diagonal members 8 and are joined to the horizontal frame member 6 serving as an intermediate rail. In each partition layer b, the spread side ends of the two diagonal members 8 may be joined to the vertical frame member 3.

  The deformation absorbing device 9 will be specifically described. The deformation absorbing device 9 of the upper partition layer b and the deformation absorbing device 9 of the lower partition layer b have the same configuration if they are turned upside down. Here, the deformation absorbing device 9 of the upper partition layer b is taken as an example. Take it.

  As shown in the enlarged views of FIGS. 9 and 10 and the perspective view of FIG. 11, the deformation absorbing device 9 includes a pair of vertical parallel plate portions 22 and 22 that are arranged in parallel with each other in the wall width direction. , An energy absorbing plate-like web portion 23 for connecting the parallel plate portions 22 and 22, and a pair of upper and lower horizontal plate portions 24 connected between the upper and lower ends of the pair of parallel plate portions 22 and 22, respectively. 24. In the example of the figure, both ends of the horizontal plate portion 24 in the wall width direction protrude from the outer surface of the parallel plate portion 22, but it does not need to protrude. The pair of parallel plate portions 22 and 22 and the horizontal plate portions 24 and 24 are made of a flat steel plate such as a strip steel, and the web portion 23 is made of a steel material described later. The parallel plate portions 22, 22 and the web portion 23 are joined by welding over substantially the entire side edge of the web portion 23, and the parallel plate portions 22, 22 and the horizontal plate portions 24, 24 are parallel plate portions. The entire length 22 is joined by welding. The web part 23 and the upper and lower horizontal plate parts 24, 24 are joined by welding over the entire length of the upper and lower edges of the web part 23. Each of these welds is, for example, fillet weld.

  Of the pair of upper and lower horizontal plate portions 24, 24, the upper horizontal plate portion 24 is bonded to the horizontal frame member 4, and the lower horizontal plate portion 24 is bonded to the approaching side ends of the pair of diagonal members 8. . Thus, in the state which installed the deformation | transformation absorption device 9, the web part 23 is arrange | positioned so that the wall surface and the parallel plate part 22 may incline.

  The web portion 23 in this case has a cross section so that a part of the longitudinal direction (wall width direction) forms a predetermined angle with respect to the wall surface and the other part of the longitudinal direction forms an angle different from the predetermined angle with respect to the wall surface. It is said to be Yamagata. In order to make the web portion 23 have a mountain-shaped cross section, for example, two flat plate steel plates 23a and 23b such as band steel are joined to each other by welding such as fillet welding, so that the web portion 23 is configured. The angle formed between the steel plate 23a and the parallel plate portion 22 and the angle formed between the steel plate 23b and the parallel plate portion 22 are the same inclination angle θ. Accordingly, as shown in FIG. 10, the horizontal cross section of the deformation absorbing device 9 forms a Σ shape with the pair of parallel plate portions 22 and 22 and the web portion 23.

  The deformation absorbing device 9 shown in FIG. 9 to FIG. 11 is formed of the web portion 23 from the upper and lower horizontal plate portions 24 and 24 respectively joined to the horizontal frame member 4 and the diagonal member 8 through a welded portion with the web portion 23. A load is transmitted to the steel plates 23a and 23b, and the web portion 23 is deformed to bend and shear, thereby absorbing energy from the earthquake. Since the web part 23 inclines with respect to the wall surface of the load-bearing wall panel 1, high deformability is obtained. Therefore, when a horizontal load along the wall surface of the load-bearing wall panel 1 is received due to an earthquake or the like without using a low yield point steel as a material or applying a slit or the like to the web portion 23, sufficient deformation is caused. Capability can be secured.

  The shear strength / rigidity of the deformation absorbing device 9 includes the thickness of the web portion 23, the length h (FIG. 9), the depth, and the inclination angle θ (FIG. 10) with respect to the parallel plate portions 22 and 22 of the steel plates 23a and 23b. It can be easily adjusted by changing. By adjusting the shear strength / rigidity of the deformation absorbing device 9, the load / deformation history of the partition layer b can be controlled. In addition, since the web portion 23 has an angled cross-sectional shape and the surface thereof is composed of a plurality of surfaces, the web portion 23 is formed as a single flat plate with an area in which two steel plates 23a and 23b are arranged. The thickness of the load-bearing wall panel 1 in the wall thickness direction is reduced, and the deformation absorbing device 9 is easily contained within the thickness range of the load-bearing wall panel 1. Further, since the length of the buckling surface can be shortened, the buckling strength is also improved.

  In addition, when big deformation performance is calculated | required, bigger deformation performance can be ensured by setting the said inclination-angle (theta) of the web part 23 to 60 degrees etc., for example. If necessary, the web portion 23 may be provided with a cross-sectional defect portion such as a hole or a slit to adjust the shear strength / rigidity, and the material of the web portion 23 may be a low yield point steel or an extremely low yield point steel. It may be used to further increase the deformation capability.

  FIG. 12 shows an enlarged horizontal section in the vicinity of the adjacent portion of the two load-bearing wall panels 1 and 1 in a state where the outer wall panel is provided with an exterior material or the like. On the outdoor side of the panel frame 2, an exterior surface material 43 is stretched through a base material 41 made of plywood and an air layer 42, and both sides of the corrugated steel plate 7 are placed in the panel frame 2 where the corrugated steel plate 7 is stretched. Are filled with heat insulating materials 44 and 45 such as glass wool. An interior surface member 46 is stretched on the indoor side of the panel frame 2. On the outdoor side and indoor side of the vertical frame member 3 adjacent to the two load-bearing wall panels 1 and 1, a column heat insulating surface material 47 made of glass wool board or the like is stretched.

  According to this load-bearing wall panel 1, it is divided into a plurality of partition layers a and b arranged vertically, and the load bearing elements of some partition layers a are corrugated steel plates 7 and the load bearing elements of other partition layers b are diagonal members 8. The partition layer b, whose strength element is the diagonal member 8, can be provided with openings (not shown) for facilities, daylighting, etc. without lowering the strength and disadvantages in construction.

  The partition layer a whose proof stress element is the corrugated steel sheet 7 has a history similar to a spindle type and has an excellent energy absorption performance. The partition layer b whose strength element is the diagonal member 8 is higher in rigidity than the partition layer a using the corrugated steel plate 7 as it is, but because the deformation absorbing device 9 that absorbs deformation of the partition layer b is provided, It can be easily adjusted to have the same rigidity as the partition layer a using the corrugated steel sheet 7. Therefore, while using the partition layer a using the corrugated steel sheet 7 and the partition layer b using the diagonal member 8 as the load-bearing elements, the waist frame-like properties of the vertical frame member 3 caused by using different types of load-bearing elements are prevented. Can do. Since the deformation absorbing device 9 that absorbs deformation is used, the rigidity of the partition layer b can be adjusted by the deformation absorbing device 9, and the strength of each of the horizontal frame members 4 to 6 and the diagonal member 8 can be changed to design the partition layers a, Unlike the case of adjusting the rigidity of b, the rigidity can be easily adjusted without performing complicated structural calculations.

FIGS. 13A to 13C show examples of the arrangement of the partition layer a provided with the corrugated steel sheet 7 as the load-bearing element, the partition layer b provided with the diagonal member 8, and the arrangement of the deformation absorbing device 9. ing. In any case, the total number of partition layers a and b is four, and the partition layer a provided with the corrugated steel plate 7 and the partition layer b provided with the diagonal member 8 are both provided at two locations. FIG. 13A is an example of the load-bearing wall panel 1 of FIG.
In the example of FIG. 13B, the partition layer b provided with the diagonal member 8 is set at two locations on the center side, and in these partition layers a, the two diagonal members 8 both have the upper end side at the intersection side, A deformation absorbing device 9 is disposed in the vicinity.
In the example of FIG. 13C, the partition layer b provided with the diagonal material 8 is set at two locations on the central side, as in the example of FIG. The diagonal directions 8 are opposite to each other, and the diagonal member 8 of the upper partition layer b and the diagonal member 8 of the lower partition layer b are arranged in a straight line so as to form an X shape. The deformation absorbing device 9 is disposed at the intersection of the four diagonal members 8. In this case, the deformation absorbing device 9 is provided separately for each partition layer b, but may be configured to absorb deformation of the two partition layers b by one.

  13A to 13C, the total of the partition layers a and b is four, but the total of the partition layers a and b may be three or five, for example. Further, the number of partition layers a provided with corrugated steel plates 7 as the load bearing elements and the number of partition layers b provided with diagonal members 8 may be different from each other.

In the above embodiment, the case where the load-bearing elements of the load-bearing wall panel 1 are the corrugated steel plates 7 and the diagonal members 8 has been described. However, all of the load-bearing elements are the corrugated steel plates 7 as shown in FIGS. It is good as a thing. In the example of FIG. 14, the load-bearing wall panel 1 is partitioned into four partition layers arranged vertically, and the load-bearing element of each partition layer is a corrugated steel plate 7. In the example of FIG. 15, the load-bearing wall panel 1 is not partitioned into a plurality of partition layers, and a single corrugated steel sheet 7 is stretched as a load-bearing element on the entire surface of one partition surrounded by the panel frame 2.
In addition to this, as shown in FIG. 16, the load-bearing wall panel 1 is divided into four partition layers a and b arranged vertically, and two diagonal members 8 are used as load-bearing elements for the upper partition layer b. The deformation absorbing device 9 is not provided, and the other three partition layers a may be configured to use the corrugated steel plate 7 as a load bearing element.

  In addition, in the edge part reinforcement fixing structure of the load bearing element corrugated steel plate of each said embodiment, you may fix the overlap reinforcement part 10 to the panel frame 2 by welding instead of fixing with the fixing tool 11 of FIG.
