Patent No. 5805893

In the load-bearing wall disclosed in Patent Document 1, a wall material is joined to the surfaces of a pair of vertical members. For this reason, in the above-mentioned load-bearing wall, when a horizontal load such as an earthquake is applied, a force that twists the vertical member acts on the vertical member. Here, if the vertical members are made of wooden materials that have lower strength and stiffness than metal materials, it is necessary to (before deformation occurs), there is a risk of damage to the vertical members or the joints between the vertical members and the wall material.

As mentioned above, before the load-bearing wall undergoes large deformation due to horizontal loads, damage may occur in the vertical members or the joints between the vertical members and the wall surface material, making it difficult for the load-bearing wall to stably deform to a large deformation. do not have.

The present invention takes the above facts into consideration, and in a configuration including a metal wall material and a wooden vertical frame material, while suppressing damage to the vertical frame material or the joint between the vertical frame material and the wall material, It is an object of the present invention to provide a load-bearing wall that can maintain stable strength even during large deformations, and a wooden building using this load-bearing wall.

The load-bearing wall of the first aspect of the present invention includes a metal wall material in which openings are formed at intervals in the vertical direction, and is provided along an edge of the opening of the wall material, and is provided from the edge to the an annular rib protruding in the thickness direction of the wall material; and a pair of vertical frame members extending in the vertical direction and having both widthwise ends of the wall material joined to each other, and the vertical frame member includes the In the width direction of the wall material, a first vertical member made of wood is arranged on one side in the thickness direction of the wall material and the first vertical member is arranged on the other side in the thickness direction of the wall material. a second wooden vertical member sandwiching the ends;

In the load-bearing wall of the first aspect, since the vertical frame material is joined to the wall material with both ends of the wall material in the width direction sandwiched between the first vertical member and the second vertical member, for example, Compared to a structure in which the wall material is joined to the surface of the vertical frame material, the wall material is located closer to the center in the wall thickness direction. That is, the eccentricity in the wall thickness direction between the wall surface material and the vertical frame material is reduced. For this reason, when the load-bearing wall of the first aspect is placed between adjacent pillars of a wooden frame, and a pair of vertical frame members are respectively connected to the adjacent pillars, horizontal loads due to earthquakes, etc. are transmitted to the load-bearing wall. Even if the vertical frame members (the first vertical member and the second vertical member) are twisted, the force acting on the vertical frame members is reduced, so that the joints between the vertical frame members and the vertical frame members and the wall material are reduced. This prevents damage from occurring.
In addition, in the above-mentioned load-bearing wall, since the widthwise end of the wall material is sandwiched between the first vertical member and the second vertical member from the wall thickness direction, the joint between the wall material and the vertical frame material becomes a two-plane shear. , the strength and rigidity of these joints are improved. This further suppresses damage to the vertical frame material or the joint between the vertical frame material and the wall surface material.

In addition, in the above-mentioned load-bearing wall, since the openings are formed in the wall material at intervals in the vertical direction, when a horizontal load is transmitted, the portion of the wall material between the vertically adjacent openings deforms ( shear deformation). For this reason, in load-bearing walls, for example, compared to a structure in which no opening is formed in the wall material, the wall material is more likely to undergo shear deformation due to horizontal loads, causing damage to the vertical frame material or the joint between the vertical frame material and the wall material. The occurrence of this can be further suppressed.
In this way, in the above-mentioned load-bearing wall, damage to the vertical frame material or the joint between the vertical frame material and the wall material is suppressed, before the wall material undergoes large deformation due to horizontal loads caused by earthquakes, etc. The material can be stably deformed up to large deformations. In other words, the load-bearing wall can maintain stable load-bearing strength until it undergoes large deformation. As a result, the load-bearing wall of the first aspect can stably absorb earthquake energy and the like.

In the load-bearing wall of the second aspect of the present invention, in the load-bearing wall of the first aspect, both end portions of the wall material in the width direction are provided with folded portions that are folded back from the end portions inward in the width direction. The wall material is joined to the vertical frame material with the folded portion overlapping the wall material.

In the load-bearing wall of the second aspect, the folded portion overlaps the wall material, and the wall material is joined to the vertical frame material with the widthwise end of the wall material being sandwiched between the first vertical member and the second vertical member. ing. That is, in the above-mentioned load-bearing wall, since the metal plate is doubled in the part sandwiched between the first vertical member and the second vertical member, for example, the metal plate is doubled in the part sandwiched between the first vertical member and the second vertical member. Compared to a single structure, the strength and rigidity of the joint between the wall material and the folded portion and the vertical frame material are improved. As a result, in the above-mentioned load-bearing wall, damage to the wall material and the joint between the folded portion and the vertical frame material is further suppressed from occurring before the wall material undergoes large deformation.

In the load-bearing wall of the third aspect of the present invention, in the load-bearing wall of the first aspect or the second aspect, the rib protrudes to the other side in the thickness direction of the wall material, and the cross-sectional area of the second vertical member is is smaller than the cross-sectional area of the first longitudinal member.

In the load-bearing wall of the third aspect, the cross-sectional area of the second vertical member disposed on the protruding side of the rib in the thickness direction of the wall material is smaller than the cross-sectional area of the first vertical member. Compared to a configuration in which the cross-sectional area of the first vertical member is greater than or equal to the cross-sectional area of the second vertical member, the deviation between the shear center of the wall as a whole including the wall surface material and the vertical frame material and the axis of the wall becomes smaller. As a result, in the above-mentioned load-bearing wall, twisting of the vertical frame members (first vertical member and second vertical member) is suppressed when a horizontal load is applied, and damage occurs at the joint between the vertical frame member and the wall surface material. is suppressed.

A load-bearing wall according to a fourth aspect of the present invention is the load-bearing wall according to any one of the first to third aspects, and includes at least two of the wall materials, and between the pair of vertical frame materials, The intermediate frame member extending in the vertical direction is disposed, and the widthwise end of one of the wall materials and the widthwise end of the other wall material overlap in the thickness direction, and the It is joined to the intermediate frame material.

In the load-bearing wall of the fourth aspect, the widthwise end of one wall material and the widthwise end of the other wall material overlap in the wall thickness direction and are joined to the intermediate frame material. In other words, in the above-mentioned load-bearing wall, since the intermediate frame material is joined to the double layered portion where the two wall materials overlap in the wall thickness direction, the strength and strength of the joint between the wall material and the intermediate frame material are reduced. Improves rigidity. Thereby, in the above-mentioned load-bearing wall, damage to the joint between the intermediate frame and the wall material is further suppressed from occurring before the wall material undergoes large deformation.

The load-bearing wall according to a fifth aspect of the present invention is the load-bearing wall according to any one of the first to fourth aspects, which extends in the width direction of the wall material, and has an upper end portion and a lower end portion of the wall material joined together. It further includes a pair of horizontal frame members.

In the load-bearing wall of the fifth aspect, the upper end and the lower end of the wall material are respectively joined to a pair of horizontal frame members extending in the width direction of the wall material. For this reason, the load-bearing wall of the fifth aspect is placed between adjacent column materials of a wooden frame, and the upper frame material is joined to the upper beam material, and the lower frame material is joined to the lower beam material. When a horizontal load due to an earthquake is transmitted, the force acting on the joint between the vertical frame and the wall material is dispersed to the joint between the horizontal frame and the wall material. This prevents damage from occurring at the joint with the

In the load-bearing wall of the sixth aspect of the present invention, in the load-bearing wall of any one of the first to fourth aspects, the shape and size of the opening are the same when the wall material is viewed from the thickness direction.

In the load-bearing wall of the sixth aspect, since the shape and size of the openings are the same when the wall material is viewed from the thickness direction, for example, compared to a structure in which at least one of the shape and size of the openings is different, the openings and The stress acting on each rib provided at the edge of the opening can be made constant. This suppresses early shear buckling in the wall material. In addition, when forming openings and ribs in wall materials, there is no need to use various processing tools (including molds) that match the shape and size of the openings and ribs, making it easier to manufacture (process) load-bearing walls. Become.

In the load-bearing wall of the seventh aspect of the present invention, in the load-bearing wall of the sixth aspect, the shape of the opening is circular when the wall material is viewed from the thickness direction.

In the load-bearing wall of the seventh aspect, since the opening has a circular shape when the wall material is viewed from the thickness direction, for example, compared to a configuration in which the opening has a polygonal shape, when a horizontal load is applied, Local stress concentration on the opening and the ribs provided at the edge of the opening is alleviated, and stable yield strength can be maintained until large deformations occur.

A wooden building according to an eighth aspect of the present invention includes a wooden frame assembled from a plurality of columns and a plurality of beams, and a load-bearing wall according to any one of the first to seventh aspects used for the wooden frame; In the load-bearing wall, a pair of vertical frame members are respectively joined to the adjacent pillar members while being arranged between the adjacent pillar members.

Even if a horizontal load due to an earthquake or the like is transmitted to a load-bearing wall, in the load-bearing wall of any one of the first to seventh aspects, the relationship between the vertical frame material or the vertical frame material and the wall surface material may be damaged before large deformation occurs. Since damage to the joints is suppressed, stable yield strength can be maintained until large deformations occur. In the wooden building of the eighth aspect, since the above load-bearing walls are used, seismic energy is stably absorbed by the load-bearing walls, so that seismic performance is improved.

According to the present invention, in a configuration including a metal wall material and a wooden vertical frame material, damage to the vertical frame material or the joint between the vertical frame material and the wall material can be suppressed, and even when large deformation occurs.

In this state, the first frame member 60 and second frame member 62 may be joined to the wall material 22 using the joining tool 34, and the joining tool 34 may be used with the wall material 22 sandwiched between the vertical members. The wall material 22 and each of the vertical members are joined together using the joining tool 34 with the wall material 22 sandwiched between each of the horizontal members, and then the vertical members and the horizontal members are connected. may be formed.
Although the present embodiment has a configuration in which the vertical members and the horizontal members are connected, the present invention is not limited to this configuration, and a configuration in which the vertical members and the horizontal members are not connected may be used.

As shown in FIGS. 1 and 4, the distance D1 between the centers of vertically adjacent openings 28 is defined along the horizontal direction (wall width direction) between the joints 36 between a pair of vertical frame members 26 and wall members 22. This distance is shorter than the horizontal distance D2 (see FIG. 5). In addition, the horizontal distance D2 here is the distance along the wall width direction from the center of one joint part 36 in the wall width direction to the center of the other joint part 36 in the wall width direction. Further, the width W1 of the opening 28 along the horizontal direction (wall width direction) is set within a range of 30% to 80% of the horizontal distance D2.

Next, the operation and effects of this embodiment will be explained.

FIG. 9(A) shows the load-bearing wall 70 of Comparative Example 1. This load-bearing wall 70 is constructed on the surface of a wooden frame member 76 that is composed of a pair of vertical frame members 72 and a pair of horizontal frame members 74 that connect the upper ends and lower ends of the pair of vertical frame members 72. This is a load-bearing wall in which the wall material 22 of the first embodiment is joined using a joining tool 34. When a horizontal load HL due to an earthquake or the like is transmitted to the load-bearing wall 70 with such a load-bearing wall 70 installed between adjacent pillars 104 of the wooden frame 102, as shown in FIG. 9(A), A force F that twists the vertical frame member 72 acts on the vertical frame member 72. Here, if the vertical frame material 72 is made of wood having lower strength and rigidity than the metal wall material 22, the performance of the wall material 22 may not be fully exhibited against the horizontal load HL. Before (before the wall material 22 undergoes large deformation), the vertical frame material 72 is twisted and damaged as shown in FIG. 9(B), or the vertical frame material 72 is damaged as shown in FIG. 9(C). There is a possibility that the joint tool 34 may be pulled out from the vertical frame material 72 and the joint between the vertical frame material 72 and the wall surface material 22 may be damaged.

As mentioned above, if damage occurs to the vertical frame material or the joint between the vertical frame material and the wall material before the load-bearing wall undergoes major deformation due to horizontal loads, the load-bearing wall (wall material) may undergo major deformation. It cannot be stably deformed. Therefore, load-bearing walls are required to be able to maintain stable strength even during large deformations while suppressing damage to the vertical frame materials and the joints between the vertical frame materials and the wall surface materials. Taking these matters into consideration, the present inventors have developed the present invention.

In the load-bearing wall 20 of this embodiment, the vertical frame member 26 is joined to the wall member 22 with both width end portions 22A of the wall member 22 being sandwiched between the first vertical member 30 and the second vertical member 32, respectively. Therefore, compared to, for example, a configuration in which the wall material 22 is joined to the surface of the vertical frame material 72 as in Comparative Example 1, the wall material 22 is located closer to the center in the wall thickness direction. That is, the eccentricity in the wall thickness direction between the wall surface material 22 and the vertical frame material 26 is reduced. For this reason, the load-bearing wall 20 of this embodiment is arranged between the adjacent pillars 104 of the wooden frame 102, and the pair of vertical frames 26 are respectively joined to the adjacent pillars 104, as shown in FIG. 10(A). As shown, even when the horizontal load HL is transmitted to the load-bearing wall 20, the force F acting on the vertical frame members 26 (first vertical members 30 and second vertical members 32) that twists the vertical frame members 26 is reduced. Ru. Thereby, in the load-bearing wall 20, twisting of the vertical frame member 26 is suppressed, and pulling out of the joint tool 34 from the vertical frame member 26 is suppressed (see FIG. 10(B)). That is, in the load-bearing wall 20, damage to the vertical frame material 26 or the joint portion 36 between the vertical frame material 26 and the wall surface material 22 can be suppressed from occurring due to the horizontal load HL.

In addition, in the load-bearing wall 20, since the width end portion 22A of the wall material 22 is sandwiched between the first vertical member 30 and the second vertical member 32 from the wall thickness direction, the joint portion 36 between the wall material 22 and the vertical frame material 26 becomes a two-plane shear, and the proof strength and rigidity of these joints 36 are improved. This further suppresses damage to the vertical frame material 26 and the joint portion 36 between the vertical frame material 26 and the wall surface material 22.

Furthermore, in the load-bearing wall 20, since the openings 28 are formed in the wall material 22 at intervals in the vertical direction, when the horizontal load HL is transmitted, the gap between the vertically adjacent openings 28 in the wall material 22 is The parts are easily deformed (shear deformation). Therefore, in the load-bearing wall 20, the wall material 22 is easily sheared and deformed by the horizontal load HL, and the vertical frame material 26 and the wall surface Damage to the joint portion 36 with the material 22 can be further suppressed.

In this way, in the load-bearing wall 20, damage to the vertical frame material 26 and the joint 36 between the vertical frame material 26 and the wall material 22 can be suppressed from occurring before the wall material 22 is significantly deformed by the horizontal load HL. Therefore, the wall material 22 can be stably deformed up to large deformations. In other words, the load-bearing wall 20 can maintain stable load-bearing strength until it undergoes large deformation. As a result, the load-bearing wall 20 can stably absorb earthquake energy and the like. In the wooden building 100 using such a load-bearing wall 20, earthquake energy is stably absorbed by the load-bearing wall 20, so that seismic performance is improved.

Further, in the load-bearing wall 20, an upper frame member 40 is joined to the upper end portion 22D of the wall member 22, and a lower frame member 50 is joined to the lower end portion 22E of the wall member 22. For this reason, a state in which the pair of vertical frame members 26 of the load-bearing wall 20 are respectively joined to the adjacent column members 104, the upper frame member 40 is joined to the upper beam member 106, and the lower frame member 50 is joined to the lower beam member 108. When the horizontal load HL is transmitted to the load-bearing wall 20, the force acting on the joint 36 between the vertical frame member 26 and the wall material 22 is applied to the joint 46 between the upper frame member 40 and the wall member 22, and the lower Since they are distributed at the joints 56 between the frame material 50 and the wall material 22, damage to the joints 36 between the vertical frame material 26 and the wall material 22 is suppressed.

In addition, in the load-bearing wall 20, since all the openings 28 have the same shape and size when the wall material 22 is viewed from the wall thickness direction, for example, the openings 28 may have a different shape and/or size. In comparison, the stress acting on each of the openings 28 and the annular ribs 24 provided at the edges of the openings 28 can be made constant. Thereby, early shear buckling of the wall material 22 is suppressed. Furthermore, when forming the openings 28 and the annular ribs 24 in the wall material 22, there is no need to use various processing tools (including molds) that match the shapes and sizes of the openings 28 and the annular ribs 24. Manufacturing (processing) becomes easier.

Furthermore, in the load-bearing wall 20, since the shape of all the openings 28 is circular when the wall material 22 is viewed from the wall thickness direction, the horizontal load HL When this occurs, the local stress concentration on the opening 28 and the annular rib 24 is alleviated, and stable yield strength can be maintained until large deformations occur.

In the load-bearing wall 20, since the center-to-center distance D1 is shorter than the horizontal distance D2, when the horizontal load HL is transmitted to the load-bearing wall 20, the horizontal direction between the pair of joints 36 and the opening 28 in the wall material 22 The shear stress (von Mises stress) value in the intermediate portion 22G is lower than the shear stress value in the vertical intermediate portion 22F between the vertically adjacent openings 28. As a result, in the load-bearing wall 20, before the vertical intermediate portion 22F between the vertically adjacent openings 28 in the wall material 22 is deformed, the joint 36 between the vertical frame material 26 and the wall material 22 is damaged. is suppressed, and stable yield strength can be maintained even during large deformations.

In addition, in the load-bearing wall 20, since the width W1 is within the range of 30% to 80% of the horizontal distance D2, before the intermediate portion 22F between the vertically adjacent openings 28 in the wall material 22 is deformed, Damage to the joint 36 between the frame material 26 and the wall surface material 22 can be effectively suppressed.

In the load-bearing wall 20, since an opening 28 is formed in the wall material 22, piping and wiring can be carried out using this opening 28. For this reason, in the load-bearing wall 20, for example, compared to a structure in which no opening is formed in the wall material, there is no need to detour piping or wiring, and there is no need to process through holes in the wall material on-site, so the construction site Labor saving can be achieved. Furthermore, by forming the opening 28 in the wall material 22, weight reduction can be achieved.

In addition, since the load-bearing wall 20 has a structure in which the width end portion 22A of the wall material 22 is sandwiched between the first vertical member 30 and the second vertical member 32, the width of the wooden frame 102 can be adjusted by appropriately adjusting the dimensions of this sandwiched portion. It becomes possible to absorb dimensional tolerances and construction errors in the load-bearing wall 20.

In the first embodiment, one row of openings 28 is formed in the wall material 22 that constitutes the load-bearing wall 20, but the present invention is not limited to this configuration. For example, as in a load-bearing wall 80 shown in FIG. 11, a plurality of rows (two rows in the load-bearing wall 80) of openings 28 may be formed in a wall material 82 constituting the load-bearing wall 80. Since this load-bearing wall 80 is used when the distance between adjacent pillar members 104 is wide, the width of the wall member 82 in the wall width direction is wider than in the first embodiment. If such a load-bearing wall 80 is installed between adjacent column members 104, the rigidity of the portion between the two rows of openings 28 in the wall member 82 will be insufficient, so in FIG. 11 and FIG. An intermediate frame member 84 is arranged, and the intermediate frame member 84 and the wall member 82 are joined to reinforce the above-mentioned portion of the wall member 82. Note that the intermediate frame member 84 has an upper end portion joined to the upper frame member 40 and a lower end portion joined to the lower frame member 50. Specifically, the intermediate frame member 84 includes a first vertical member 86 disposed on a plate surface 82A on one side in the wall thickness direction of the wall material 82, and a plate surface on the opposite side to the plate surface 82A of the wall material 82. 82B, and is joined to the wall material 82 by driving the joining tool 34 from the first vertical member 86 to the second vertical member 88. In addition, below, the joint part by the joint tool 34 of the intermediate frame material 84 and the wall surface material 82 is described as the joint part 90. A plurality of these joint portions 90 are formed at intervals in the wall width direction. Here, as shown in FIG. 12, in the load-bearing wall 80, the distance D1 between the centers of vertically adjacent openings 28 is shorter than the horizontal distance D2 from one or the other joint 36 to the joint 90. . The width W1 of the opening 28 is set within a range of 30% to 80% of the horizontal distance D3. With these configurations, in the load-bearing wall 80, when the horizontal load HL is transmitted to the load-bearing wall 80, the shear stress (Mieses stress) in the horizontal intermediate portion between one joint 36 and the opening 28 in the wall material 82 is reduced. ) and the shear stress value at the horizontal intermediate portion between the joint portion 90 and the opening 28 are lower than the shear stress value at the vertical intermediate portion between the vertically adjacent openings 28. As a result, in the load-bearing wall 80, damage to the joint portion 36 and the joint portion 90 is suppressed before the intermediate portion between the vertically adjacent openings 28 in the wall material 82 is deformed, and the load-bearing wall 80 is stable until large deformation occurs. It can maintain a certain strength. Note that the reference numeral 92 shown in FIGS. 11 and 12 is a frame member in which the first vertical member 86 is incorporated into the first frame member 60, and the reference numeral 94 is a frame member in which the second vertical member 88 is incorporated in the second frame member 62. It is a frame material. Further, the first vertical member 86 and the second vertical member 88 that constitute the intermediate frame member 84 have the same size and shape.

[Second embodiment]
A load-bearing wall 110 according to a second embodiment of the present invention will be described. Note that the same members as in the first embodiment are given the same reference numerals, and overlapping explanations will be omitted or simplified.

As shown in FIGS. 13 and 14, the load-bearing wall 110 of this embodiment is used for a wooden frame 102 in which the distance between adjacent pillars 104 is wider than that of the first embodiment. Therefore, as shown in FIGS. 13 and 14, the load-bearing wall 110 is constructed using two wall materials 22 of the first embodiment (two wall materials 22 of the same size and shape are used). .

Specifically, the intermediate frame member 112 includes a first vertical member 114 and a second vertical member 116, and these first vertical members 114 and second vertical members 116 form two wall members 22. The overlapping parts of the walls are sandwiched in the wall thickness direction. Then, the joining tool 34 is driven from the first vertical member 114 toward the second vertical member 116, thereby joining the intermediate frame member 112 and the two wall members 22. In addition, below, the joint part by the joint tool 34 of the intermediate frame material 112 and the wall surface material 22 is described as the joint part 118. A plurality of these joint parts 118 are formed at intervals in the vertical direction. Here, as shown in FIG. 14, in the load-bearing wall 110, the distance D1 between the centers of vertically adjacent openings 28 is shorter than the horizontal distance D2 from one or the other joint 36 to the joint 118. .

Note that the reference numeral 120 shown in FIGS. 13 and 14 is a frame material in which the first vertical member 114 is incorporated into the first frame member 60, and the reference numeral 122 is a frame member in which the second vertical member 116 is incorporated in the second frame member 62. It is a frame material. Further, the first vertical member 114 and the second vertical member 116 that constitute the intermediate frame member 112 have the same size and shape.

Note that descriptions of the functions and effects obtained by the configuration similar to those of the first embodiment will be omitted.

In the load-bearing wall 110, the width end portion 22A of the first wall material 22 and the width end portion 22A of the second wall material 22 are overlapped in the wall thickness direction, and this overlapped portion is used as the first vertical member 114 and the second vertical member 114. The two wall materials 22 are joined to the intermediate frame material 112 by a joining tool 34 while being sandwiched between the vertical members 116. Here, in the load-bearing wall 110, since the intermediate frame material 112 is joined to the portion where the two wall materials 22 overlap in the wall thickness direction and become double, the two wall materials 22 and the intermediate frame material The strength and rigidity of the joint with 112 are improved. Thereby, in the load-bearing wall 110, damage to the joint 118 between the intermediate frame member 112 and the two wall members 22 is further suppressed from occurring before the wall member 22 undergoes large deformation.

Furthermore, since the load-bearing wall 110 uses two wall materials 22 having the same size and shape, parts management is easier and production costs can be reduced compared to a configuration using wall materials with different dimensions and shapes.

In the load-bearing wall 110 of the second embodiment, two wall materials 22 are arranged in the same direction in the wall width direction, and the width end portion 22A of the first wall material 22 and the width end portion of the second wall material 22 are arranged in the same direction in the wall width direction. 22A are overlapped, and the two wall materials 22 and the intermediate frame material 112 are joined using a joining tool 34 at this overlapping portion, but the present invention is not limited to this configuration. For example, two wall materials 22 may be arranged in the same direction in the wall width direction so that their width ends 22A do not overlap each other, and each width end 22A may be joined to the intermediate frame material 112 using the joining tool 34. good. Note that in order to arrange the width ends 22A of the two wall materials 22 in the wall width direction so that they do not overlap, the width ends 22A of the two wall materials 22 should be in contact with each other. This includes those arranged side by side with their respective width ends 22A separated from each other.

[Third embodiment]
A load-bearing wall 130 according to a third embodiment of the present invention will be described. Note that the same members as in the first embodiment are given the same reference numerals, and overlapping explanations will be omitted or simplified.

As shown in FIG. 15, the load-bearing wall 130 of this embodiment includes the wall material 22 of the first embodiment and a folded portion 132 provided at the width end portion 22A of this wall material 22. Specifically, the folded portion 132 is a portion folded back inward in the wall width direction from the width end portion 22A of the wall material 22, and is integrally molded with the wall material 22. The wall material 22 is joined to the vertical frame material 26 with the folded portion 132 overlapping the wall material 22. Specifically, the wall material 22 and the folded portion 132 overlapping the wall material 22 are sandwiched between the first vertical member 30 and the second vertical member 32 in the wall thickness direction, and are joined by the joining tool 34. ing. In addition, below, the joint part by the joint tool 34 of the vertical frame material 26 and the wall surface material 22 is described as the joint part 134. A plurality of these joint parts 134 are formed at intervals in the vertical direction.

Next, the operation and effects of this embodiment will be explained.
Note that descriptions of the functions and effects obtained by the configuration similar to those of the first embodiment will be omitted.

In the load-bearing wall 130, the folded portion 132 overlaps the wall material 22, and the wall material 22 is folded into the vertical frame material 26 with the width end portion 22A of the wall material 22 being sandwiched between the first vertical member 30 and the second vertical member 32. is joined to. That is, in the load-bearing wall 130, since the metal plate is doubled in the portion sandwiched between the first vertical member 30 and the second vertical member 32, for example, the metal plate is doubled at the portion sandwiched between the first vertical member 30 and the second vertical member 32 Compared with a structure in which a single metal plate is used in a portion, the strength and rigidity of the joint portion 134 between the wall material 22 and the folded portion 132 and the vertical frame member 26 are improved. As a result, in the above-mentioned load-bearing wall, damage to the wall material 22 and the joint portion 134 between the folded portion 132 and the vertical frame member 26 is further suppressed from occurring before the wall material 22 undergoes large deformation.

In the third embodiment, the folded portion 132 is provided at the width end portion 22A of the wall material 22, but the present invention is not limited to this configuration. For example, folded portions may be provided at the upper end 22D and lower end 22E of the wall material 22, respectively.

[Fourth embodiment]
A load-bearing wall 140 according to a fourth embodiment of the present invention will be described. Note that the same members as in the first embodiment are given the same reference numerals, and overlapping explanations will be omitted or simplified.

The second frame member 142 has a pair of second vertical members 144, a second cross member 44, and a second cross member 54. The cross-sectional area of the second longitudinal member 144 is smaller than the cross-sectional area of the first longitudinal member 30. Specifically, the width of the second vertical member 144 along the wall width direction is narrower than the width of the first vertical member 30 along the wall width direction, and the cross-sectional area of the second vertical member 144 is smaller than the width of the first vertical member 30 along the wall width direction. 1 is made smaller than the cross-sectional area of the vertical member 30.

For example, compared to a configuration in which the cross-sectional area of the first vertical member 30 is greater than or equal to the cross-sectional area of the second vertical member 144, the deviation between the shear center of the wall as a whole including the wall member 22 and the vertical frame member 146 and the axis of the wall becomes smaller. As a result, in the load-bearing wall 130, twisting of the vertical frame members 146 (the first vertical members 30 and the second vertical members 144) when the horizontal load HL is applied is suppressed, and the joint between the vertical frame members 146 and the wall member 22 is suppressed. Damage to the joint 148 caused by the tool 34 is suppressed.

In the load-bearing wall 140 of the fourth embodiment, the width along the wall width direction of the second vertical member 144 is made narrower than the width along the wall width direction of the first vertical member 30, and the cross section of the second vertical member 144 is Although the area is smaller than the cross-sectional area of the first vertical member 30, the present invention is not limited to this configuration. For example, like the load-bearing wall 150 shown in FIG. 17, the thickness of the second vertical member 154 along the wall thickness direction is made thinner than the thickness of the first vertical member 30 along the wall thickness direction, 154 may be smaller than the cross-sectional area of the first longitudinal member 30. In addition, the code|symbol 152 in FIG. 17 shows the 2nd frame member which has a pair of 2nd vertical member 154, the 2nd horizontal member 44, and the 2nd horizontal member 54, and the code|symbol 156 shows the 1st vertical member 30 and the 2nd vertical member. A vertical frame member made of a material 154 is shown, and reference numeral 158 indicates a joint portion between the vertical frame member 156 and the wall surface material 22 by the joint tool 34.

In the embodiment described above, the opening 28 has a circular shape when viewed from the wall thickness direction, but the present invention is not limited to this configuration. For example, the opening 28 may have an elliptical shape or a polygonal shape.

Further, in the above-described embodiment, all the openings 28 have the same shape and size when viewed from the wall thickness direction, but the present invention is not limited to this configuration. For example, adjacent openings 28 may have different shapes and sizes.

In the embodiment described above, the joining tools (jointing tools 34, 38) are driven perpendicularly to the object to be joined, but the present invention is not limited to this configuration, and the joining tools may be driven diagonally to the object to be joined. good. For example, one joint tool 38 is driven diagonally from the surface of the first cross member 42 (the surface opposite to the wall material 22) toward the upper beam member 106, and the other joint tool 38 is driven into the surface of the second cross member 44. It may be driven diagonally from the side opposite to the wall material 22 toward the upper beam material 106 in the opposite direction to the first joining tool 38 described above.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and can be implemented with various modifications other than the above without departing from the spirit thereof. Of course.
