The northern end of the beam 160 is fixed to the through column 110d.

As described above, the waist wall 100 according to the first embodiment is
It is a waist wall provided in house 1 (building),
The upper beam 120 (first horizontal member) laid horizontally on the upper end of the waist wall 100,
The lower end is fixed to the foundation 2 of the house 1, and the upper end is fixed to the middle part in the longitudinal direction (horizontal direction) of the upper beam 120 (first horizontal member) with the intermediate through pillar 113 (through pillar). , Are provided.

With such a configuration, the waist wall 100 can secure wind resistance without using a dedicated member or a special construction method.

Specifically, since the waist wall 100 is subject to wind pressure due to, for example, a wind blowing from the south side to the north side, it is easily deformed (bent) in the out-of-plane direction. However, in the waist wall 100, as described above, the intermediate through column 113 is fixed to the middle portion of the upper beam 120 in the longitudinal direction. Here, the intermediate through pillar 113 is fixed to the foundation 2 of the house 1 and constitutes the building main body 3. Therefore, even when the waist wall 100 is subjected to wind pressure, deformation in the out-of-plane direction can be effectively suppressed.

Further, the intermediate through pillar 113 constitutes the building main body 3 as described above, and is a general constituent member of the house 1. Therefore, in the waist wall 100, it is not necessary to use a dedicated member or a special construction method for effectively suppressing the deformation in the out-of-plane direction, so that it is possible to suppress an increase in component cost and deterioration in workability. can. Further, in the waist wall 100, the strength and rigidity of the members constituting the general waist wall may be increased, or a member such as a retaining beam for supporting the upper end portion of the waist wall from the out-of-plane direction may be added. It is possible to secure the wind resistance.

Further, the waist wall 100 according to the present embodiment has a length of 800 cm in the longitudinal direction, and is formed longer than a general waist wall. Therefore, the waist wall 100 is more likely to bend in the out-of-plane direction than a general waist wall, but since it has the above-mentioned configuration, it is possible to effectively secure the wind resistance.

Further, in the waist wall 100,
The upper beam 120 (first horizontal member) is
In the longitudinal direction (horizontal direction), one side and the other side sandwiching the intermediate through pillar 113 (through pillar) are formed as separate bodies.

With such a configuration, in the upper beam 120, the bending of the west side upper beam 121 (one side) and the bending of the east side upper beam 122 (the other side) as a whole of the upper beam 120 are separated. It can be smaller than the deflection when it is not formed. In this way, in the waist wall 100, the bending of the upper beam 120 can be suppressed as much as possible, and the wind resistance can be effectively secured. In particular, in the present embodiment, the upper beam 120 has a length of 800 cm in the longitudinal direction as a whole and is formed to be relatively long. Therefore, a large effect can be obtained by forming the upper beam 120 separately as described above. Can be done.

Further, in the waist wall 100,
A second horizontal member (intermediate beam 140 and lower beam 130) laid below the upper beam 120 (first horizontal member) is further provided.
The intermediate through pillar 113 (through pillar) is
It is fixed to the second horizontal member.

With such a configuration, even when a force is applied to the intermediate through column 113 in the bending direction (under wind pressure), the intermediate portion of the intermediate through column 113 in the longitudinal direction is provided by a beam different from the upper beam 120. Is fixed, so that the bending of the intermediate through column 113 can be suppressed as much as possible. In this way, the waist wall 100 can effectively secure the wind resistance.

Further, in the waist wall 100,
The second horizontal member (intermediate beam 140 and lower beam 130) is
In the longitudinal direction (horizontal direction), one side and the other side sandwiching the intermediate through pillar 113 (through pillar) are formed as separate bodies.

With such a configuration, not only the upper beam 120 as described above, but also the intermediate beam 140 and the lower beam 130 are separately formed. That is, in the intermediate beam 140, the deflection of the western intermediate beam 141 (one side) and the deflection of the east side intermediate beam 142 (the other side) as a whole of the intermediate beam 140 are not formed separately. It can be smaller than the deflection of the case. Further, in the lower beam 130, the bending of the west side lower beam 131 (one side) and the bending of the east side lower beam 132 (the other side) as a whole of the lower beam 130 are not formed separately. It can be smaller than the deflection of the case. In this way, in the waist wall 100, the bending of the intermediate beam 140 and the lower beam 130 can be suppressed as much as possible, and the wind resistance can be effectively secured.

Further, in the waist wall 100,
The second horizontal member is
The lower beam 130 (third horizontal member) laid horizontally on the lower part of the waist wall 100,
Intermediate beam 140 (fourth horizontal member) laid in the middle between the upper beam 120 (first horizontal member) and the lower beam 130 (third horizontal member) in the vertical direction. And, including
The intermediate beam 140 (fourth horizontal member) is
The width in the vertical direction is formed longer than that of the upper beam 120 (first horizontal member) and the lower beam 130 (third horizontal member).

Here, when a force is applied to the intermediate through column 113 in the bending direction (under wind pressure) on the waist wall 100, the beam is arranged at the upper end of the three beams fixed to the intermediate through column 113. The intermediate beam 140 receives a larger force than the upper beam 120 and the lower beam 130 arranged at the lower part (near the lower end portion). Therefore, the waist wall 100 is formed so that the width of the intermediate beam 140 in the vertical direction is long, and the strength of the intermediate beam 140 is set higher than that of other beams. In this way, the waist wall 100 can effectively secure the wind resistance.

In general, the waist wall is required to have various appearances from the viewpoint of design. To meet such demands, the height should not be increased (the width in the vertical direction should be increased), the length in the longitudinal direction (horizontal direction) should be increased, and the constituent materials (width in the out-of-plane direction) should not be increased. Things etc. are included. However, if such a requirement for appearance is satisfied, there is a possibility that the wind pressure resistance may be lowered. However, by adopting the structure of the waist wall 100 according to the present embodiment, it is possible to satisfy the requirements regarding the appearance and the wind pressure resistance, so that the waist wall 100 is advantageous as compared with the general waist wall. Has a good effect.

Although one embodiment has been described above, the present invention is not limited to the above configuration, and various modifications can be made within the scope of the invention described in the claims.

For example, a wooden house has been exemplified as an embodiment of a building, but the present invention is not limited to this, and a house having a structure other than a wooden structure such as a lightweight steel frame may be used. Further, the building is not limited to a house, but may be an office building, a hospital, or the like.

Further, the size of the waist wall 100, that is, the size of various members (upper beam 120 and the like) constituting the waist wall 100 is not limited to that of the present embodiment.

Further, although only the intermediate through pillar 113 (that is, only one through pillar) is arranged as a through pillar in the middle portion in the longitudinal direction of the waist wall 100, a plurality of through pillars may be arranged. Further, the place where the intermediate through pillar 113 is arranged is not limited to that according to the present embodiment, and may be, for example, a central portion in the longitudinal direction of the waist wall 100.

Further, in the present embodiment, all three beams (upper beam 120, intermediate beam 140 and lower beam 130) included in the waist wall 100 are formed separately, but the present invention is not limited to this. For example, only one of the three beams may be a separate body, or only two of the three beams may be a separate body. Further, in such a case, any of the three beams can be selected as the separate beam. The waist wall 100 does not necessarily have to be formed as a separate body from any of the three beams as long as it includes the intermediate through column 113.

Further, the configuration of the intermediate beam 140 is not limited to that according to the present embodiment. This will be described in detail below.

That is, the intermediate beam 240 is formed so as to have a plurality of steps in the vertical direction.

The first intermediate beam 240a is divided into two (first west side intermediate beam 241a and first east side intermediate beam 242a) with the intermediate through pillar 113 in the east-west direction. Further, the second intermediate beam 240b is divided into two (second west side intermediate beam 241b and second east side intermediate beam 242b) with the intermediate through pillar 113 in the east-west direction.

The first intermediate beam 240a is formed so that the vertical width (W2a shown in FIG. 8) is 21 cm. Further, the second intermediate beam 240b is formed so that the vertical width (W2b shown in FIG. 8) is 21 cm. That is, the vertical width of the intermediate beam 240 (the total length of the vertical widths of the first intermediate beam 240a and the second intermediate beam 240b) is formed longer than each of the upper beam 120 and the lower beam 130.

Is fixed, so that the bending of the intermediate through column 113 can be suppressed as much as possible. In this way, the waist wall 200 can effectively secure the wind resistance.

Further, in the intermediate beam 240, the vertical widths of the first intermediate beam 240a and the second intermediate beam 240b are formed shorter than those of the upper beam 120 and the lower beam 130, but the intermediate beam 240 as a whole is formed in the vertical direction. The width is formed longer than that of the upper beam 120 and the lower beam 130. With such a configuration, the waist wall 200 can effectively secure the wind resistance.

In the waist wall 200 according to the second embodiment, two intermediate beams 240 are arranged, but three or more intermediate beams 240 may be arranged.
