Abstract

PROBLEM TO BE SOLVED: To provide the mounting structure of a bearing wall in a building in which the width size of the opening section of the building can be ensured largely and moreover strength in the building can be ensured sufficiently. SOLUTION: The first thin-width bearing walls 4 using a steel plate as a strength element are installed so as to be projected to the indoor 5 side towards the directions orthogonal to the first exterior-wall lines 2 from the line-direction intermediate-section places of the first exterior-wall lines 2 extending from the outside angle sections 3 of the building. The second thin-width bearing walls 6 similarly using the steel plate as the strength element are mounted along the second exterior-wall lines 7 orthogonal to the first exterior-wall lines 2 towards sections parallel with the first bearing walls 4 from the outside angle section 3. In the second exterior-wall lines 7, an opening section 8 is formed on the reverse side to the outside angle sections 3, holding the second thin-width bearing walls 6.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a load-bearing wall in a building. 2. Description of the Related Art In a building having a steel frame structure or a wooden frame structure, for example, as shown in FIG. 7A, the strength of a brace structure is set along an outer wall line 51 so as to withstand an earthquake or wind pressure. The walls 52 ..., 53 ... are distributed and placed. [0003] However, in general, a load-bearing wall having a brace structure cannot sufficiently function as a load-bearing wall unless it is provided with a somewhat large width dimension. There are limitations. For this reason, as shown in FIG. 7B, in a building built on narrow land with a narrow frontage, the opening 54 on the side of the frontage is formed by the load-bearing walls 52, 52 of the brace structure inserted in the outer wall line on the side of the frontage. This causes a problem that the width dimension of the substrate becomes very small. The present invention has been made in view of the above-mentioned problems, for example, in view of the above problem, it is possible to secure a large width of an opening of a building, and yet to provide a structure for installing a load-bearing wall in a building capable of sufficiently securing a load-bearing strength in the building. The task is to provide. [0005] The object of the present invention is to form a first narrow bearing wall having a steel plate as a load-bearing element from a middle position in a line direction of a first outer wall line extending from a corner of a building. A second narrow load-bearing wall, which is installed so as to protrude toward the indoor side in a direction orthogonal to the first outer wall line and also has a steel plate as a load-bearing element, is formed from the protruding corner portion with the first load-bearing wall. It is installed so as to be parallel to and along a second outer wall line orthogonal to the first outer wall line. In the second outer wall line, an opening is formed on the side opposite to the protruding corner portion with the second narrow load-bearing wall interposed therebetween. The installation structure of a load-bearing wall in a building, characterized in that a part is formed. [0006] is solved. In this load-bearing wall installation structure,
Since a load-bearing wall using a steel plate as a load-bearing element is used, a narrow-width load-bearing wall capable of exhibiting sufficient load-bearing strength by itself can be realized. In this case, the width of the opening on the second outer wall line can be made large. [0008] In addition, the first narrow load-bearing wall, also made of a steel plate as a load-bearing element, is oriented parallel to the second narrow load-bearing wall,
The second thin wall bearing wall and the first narrow bearing wall are installed so as to protrude toward the indoor side from an intermediate position in the line direction of the first outer wall line orthogonal to the second outer wall line. Since a high proof stress can be secured by the above, the width dimension of the second narrow bearing wall can be further reduced, and the width dimension of the opening on the second outer wall line can be further secured. At the same time, the width dimension of the first narrow width bearing wall can be reduced, and the protrusion of the first narrow width bearing wall toward the indoor side can be reduced. Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 (a) and 2 (c), the installation structure of the load-bearing wall according to the first embodiment shown in FIGS. As shown in Fig. 1 (b), it is a case where it is applied.

As shown in FIG. 1A, the first outer wall line 2 extending in the longitudinal direction of the building is located at a middle position in the line direction between both corners 3 and 3 of the first outer wall line 2, and in the present embodiment, a position near the corner. , The first narrow load-bearing walls 4 are installed so as to be directed in a direction orthogonal to the first outer wall lines 2 and protrude from the first outer wall lines 2 and 2 toward the room 5. The second narrow load-bearing wall 6 is directed parallel to the first narrow load-bearing wall 4 from the protruding corners 3... And the short second outer wall line orthogonal to the first outer wall line 2. 7, an opening 8 is formed on the second outer wall line 7 between the second narrow bearing walls 6, 6 on both sides. Further, in the present embodiment, a third bearing wall 9 oriented in a direction perpendicular to the first and second narrow bearing walls 4 and 6 is adjacent to the first outer wall lines 2 and 2. It is installed between the second narrow bearing wall 6 and the first narrow bearing wall 4. The first to third bearing walls 4, 6, 9

In uniting with the load-bearing wall 6, the third load-bearing wall 9 is connected to the unit 1
0 compactly. In this bearing wall installation structure, since the bearing wall 1 having a perforated steel plate as a bearing element is used as the first and second bearing walls 4, 6, according to the bearing walls 4, 6, It is possible to realize a narrow bearing wall capable of exerting a sufficient bearing strength by itself, and the narrow bearing wall 1 is divided into the second bearing walls 6 on both sides of the opening 8 on the second outer wall line 7. , 6, it is possible to secure a large width dimension of the opening 8. In addition, the first narrow load-bearing wall 4, which also has a perforated steel plate as a load-bearing element, is oriented parallel to the second narrow load-bearing wall 6, and is an intermediate portion in the line direction of the long first outer wall line 2. The second narrow load-bearing wall 6 and the first narrow load-bearing wall 4 are installed so as to protrude from the position toward the room 5 side.
Thus, a high proof stress can be secured, so that the width of the second narrow load-bearing walls 6, 6 sandwiching the opening 8 can be reduced,
The width dimension of the opening 8 can be further increased. At the same time, the width dimension of the first narrow width bearing wall 4 can be reduced, and the protrusion of the first narrow width bearing wall 4 toward the room 5 can be reduced. In addition, the first to third narrow load-bearing walls 4, 6,

The narrow bearing walls 4 and 4 are provided. As described above, by increasing the number of the first narrow load-bearing walls 4 protruding toward the indoor side, the width dimension of the second narrow load-bearing walls 6 and 6 can be further reduced, and the opening 8 is formed. Can be secured large, and the projection of the first narrow load-bearing walls 4... Into the room 5 can be suppressed small, so that the room space 4 can be further widened. In addition, it is possible to increase the length of the building in the direction of the first outer wall line 2 while ensuring sufficient strength. Moreover, in the present embodiment, a U-shaped unit 10 of the same type as that used for the intermediate two first load-bearing walls 4, 4 protruding from the first outer wall line 2 is used at each corner of the building. The first outer wall line 2
