Description

  The present invention relates to a load bearing wall and a load bearing wall mounting structure that can sufficiently obtain daylighting in a building.

  In general, in a wooden building, in order to improve the earthquake resistance strength, a wall space surrounded by a foundation, a beam, and a column is reinforced by providing braces or extending a face material.

  Braces are plates that are arranged diagonally or in an X-shape between columns, and face materials are plates that cover the entire space between the columns. Since these are obtained, these are called bearing walls.

  By the way, in a building constructed on a narrow site, the daylight is often blocked by a neighboring building or the like, and the entire room often becomes dark. Therefore, if the window area of the wall surface is increased, these problems are solved, but the seismic strength is weakened. That is, the members that make up the window, whether movable or fitted, are final finishing fixtures made of glass fitted into the window frame, and are not involved in wall strength. If you try to secure a lighting area by enlarging the window, the wall strength will inevitably decrease.

  For this reason, on the wall surface of a house, when the wall and window are combined and lighting is important, the window area was increased as much as possible in the balance with the wall surface strength. There is a limit to the daylighting area.

  Therefore, the present invention solves the above-described problems, and the object of the present invention is to be effectively applied to new construction or renovation work that can obtain sufficient lighting while ensuring a large wall strength. A load-bearing wall and its mounting structure are provided.

In order to achieve the above-mentioned object, the bearing wall of the present invention is a surface that becomes a bearing wall that is laid out in a space surrounded by a pair of vertical members 2 and 2 and a horizontal member 1 that form a frame of a wooden building. The frame 3 is attached to a frame 4 which is made of a transparent surface material having a predetermined thickness and whose both side edges are fixed along the inner surfaces of the pair of vertical materials 2 and 2 or the horizontal material 1. It is characterized by being.
The face material 3 can be formed of glass or a translucent resin material. The face material 3 can be formed of a resin plate material having a light emitting function, so that when it does not emit light, it is transparent so that an open internal space can be formed like a transparent window, and when it emits light, the wall itself has an external line of sight. It can form the same closed interior space as a normal opaque wall. As the translucent plate material used as the translucent surface material 3, a transparent plate material, a translucent plate material, or a colored transparent plate material can be used.

  The frame body 4 is fixed to the inner surface of the vertical member 2 along the height direction thereof, and an L-shaped bracket 6 having an L-shaped cross section in a plan view, and a face member mounting surface of the L-shaped bracket 6 in the height direction. A mounting screw 8 screwed into a plurality of screw holes 6a formed at appropriate intervals and a mounting screw 8 inserted through the front and back of the end portion of the translucent surface member 3 are inserted 1 A pair of spacer plates 9, 9, a cover plate 10 through which the mounting screw is inserted on the surface opposite to the L-shaped bracket 6, and a screw 8 is fixed to the projecting end of the mounting screw 8 from the cover plate 10. The nut fixing tool 11 is provided.

  The cover plate 10 is preferably fixed in contact with and fixed to the back side bent end face of the L-shaped bracket 6 and the back side of the spacer plate 9 on the back side.

  The load bearing wall mounting structure or mounting method is as follows. The mounting screws 8 are screwed in and fixed to the L-shaped bracket 6 in advance, and after mounting on the pillar 2 by the wood screw fixture 5 of the L-shaped bracket 6, the spacer plate 9 on the front side, The translucent surface material 3, the back side spacer plate 9, and the cover plate 10 are inserted into the mounting screws 8, and the fixing tool 11 is fastened to the projecting end of the mounting screws 8 from the cover plate 9. If the assembly and the translucent face material 3 are fixed.

  With such a mounting structure, the transparent load-bearing wall of the present invention can be attached by a retrofitting work after the window sash is attached to the vertical members that are pillars on both sides of the window of the wooden building. It is possible to improve the strength of the wooden building. It is also effective to adapt to new construction work, for example, it can be adapted to the surrounding wall of the blow-by structure.

  Instead of the mounting screw 8, a mounting bar can be used. In this case, the protruding end of the mounting bar from the cover plate 10 can be fixed by welding. In this case, the plurality of screw holes 6a of the L-shaped bracket 6 may be normal holes.

  According to the present invention described above, since the face material itself constituting the bearing wall is made of a translucent plate material, it is possible to ensure a large amount of lighting while ensuring the wall surface strength. By forming the face material with a resin plate material having a light emitting function, it is transparent when it does not emit light, so it can form an open internal space like a transparent window, and when it emits light, the wall itself blocks the outside line of sight and is a normal opaque wall The same closed interior space can be formed.

  Further, according to the bearing wall mounting structure or method of the present invention, the light-transmitting surface material can be fixed while sequentially assembling the frame body from one of the indoor side or the outdoor side across the pillar as the vertical member. The work is simple and can be performed quickly, and is therefore suitable for earthquake-proof repair work, repair work for securing lighting, and the like. Moreover, it can also be adapted to new construction work, for example, it can be adapted to the surrounding wall of an atrium structure.
