Description

  The present invention relates to a method for manufacturing a load bearing wall and a load bearing wall.

Bearing walls are known as structures that resist horizontal forces such as earthquakes and wind pressure acting on buildings so that they do not fall. A bracing bearing wall using bracing as one of the bearing walls is known.
5-7 is a figure explaining the installation method of a general load-bearing wall.

  When newly creating a bearing wall at a location where a bearing wall has not been created, the ceiling 90 is first disassembled, then the floor 92 is disassembled, and then the wall 91 is disassembled, as shown in FIG. Thereafter, as shown in FIG. 6, the bracing 93 is fastened to a base (horizontal member) 94, a beam (horizontal member) 95, and a column 96. By creating a truss shape, it can resist horizontal force. Thereafter, finishing is performed as shown in FIG. 7, and the ceiling 97, the wall 98, and the floor 99 are attached. Thereby, the bracing 93 is covered with the ceiling 97, the wall 98, and the floor 99.

As described above, there is a problem that the work becomes large because a process of dismantling the ceiling and the floor is involved in creating the bearing wall.
In one aspect, the present invention aims to reduce the range of walls to be demolished.

  To achieve the above object, a disclosed method for manufacturing a load-bearing wall is provided. This manufacturing method is a method for manufacturing a load-bearing wall for a building that has at least one of a ceiling and a floor, a beam appears when the ceiling is demolished, and a foundation appears when the floor is demolished. The wall between the floor is dismantled, the shear load member is installed at a location other than the shaft assembly of each of the two pillars appearing at the dismantled location, and the wall is placed at the disassembled location.

  In one embodiment, the range of walls to be dismantled can be reduced.

It is a figure explaining the process of creating the bearing wall of an embodiment. It is a figure explaining the process of creating the bearing wall of an embodiment. It is a figure explaining the installation method of a general bearing wall. It is a figure explaining the installation method of a general bearing wall. It is a figure explaining the installation method of a general bearing wall.

Hereinafter, the bearing wall of the embodiment will be described in detail with reference to the drawings.
<Embodiment>
FIG. 1 is a diagram illustrating a wall surface before creating a bearing wall.

  The building 50 before the bearing wall is created is a part of the building. The building 50 includes a base 51, a beam 52, columns 53 and 54, an intermediate column 55, and an inner wall 56. A floor 57 is formed on the top of the base 51. A ceiling 58 is formed below the beam 52. The spacer 55 can be omitted.

The pillars 53 and 54 and the intermediate pillar 55 are covered with an inner wall 56. There is a gap between the inner wall 56 and the outer wall (not shown), and a reinforcing member described later is disposed in the gap to form a bearing wall.
2-4 is a figure explaining the process of creating the bearing wall of embodiment.

As shown in FIG. 2, when creating the bearing wall, a part of the inner wall 56 is disassembled. Specifically, unlike the example shown in FIG. 5, the inner wall 56 (at a portion corresponding to the room) between the floor 57 and the ceiling 58 is disassembled, and the floor 57 and the ceiling 58 are not disassembled. For this reason, the inner wall (second wall) of the mounting portion (inside the floor) of the base 51 and the columns 53 and 54 and the inner wall (second wall) of the mounting portion (inside the ceiling) of the beam 52 and the columns 53 and 54 are hidden. It remains.
Next, as shown in FIG. 3, the reinforcing tool (shear bearing member) 1 is attached to a portion other than the shaft assembly of the columns 53 and 54.

The reinforcing tool 1 includes a rod-shaped body (long body) 2 and brackets 3 and 3 attached to both ends of the rod-shaped body 2. A columnar member may be used instead of the rod-shaped body 2.
Examples of the constituent material of the reinforcing tool 1 include metals such as stainless steel, resins, and the like.

  The bracket 2 has a substantially U shape, and is fixed to an attachment surface with the pillars 53 and 54 via an attachment. The attachment tool is, for example, a screw or a nail. Each bracket 2 is formed by pressing a steel plate having a predetermined thickness into a substantially U shape by press forming.

  In addition, when attaching the reinforcement tool 1 to the pillars 53 and 54, it is preferable to make the angle (alpha) of the rod-shaped body 2 and a horizontal surface be 60 degree | times or more. The distance from the upper surface 51a of the base 51 to the lower portion 3a of the bracket 3 is preferably 10 cm. The distance from the lower surface 52a of the beam 52 to the upper portion 3b of the bracket 3 is preferably 40 cm.

  Thereafter, as shown in FIG. 4, an inner wall (first wall) 60 is attached to a location corresponding to the disassembled inner wall 56. As a result, the reinforcing member 1 is hidden by the inner wall 60 and the bearing wall 100 is formed. Further, a joint is formed between the inner wall 60 and the inner wall 56 above the ceiling 58. A joint is formed between the inner wall 60 and the inner wall 56 below the floor 57.

  As described above, according to the method for manufacturing the load-bearing wall 100, the load-bearing wall 100 is formed only by disassembling a part of the inner wall 56 without disassembling the floor 57 and the ceiling 58. Thereby, the dismantling range can be reduced and the bearing wall 100 can be formed easily.

  Further, it goes without saying that by attaching the reinforcing tool 1 having such a shape, the proof stress capable of resisting the horizontal force is increased as compared with the case where the reinforcing tool 1 is not attached.

Furthermore, by arranging the reinforcing tool 1 having a shape as shown in FIG. 4, it is possible to ensure the same level of proof strength as a bracing bearing wall (even if a truss shape is not formed). Moreover, breakage of the column can be suppressed.
In addition, although the example which has arrange | positioned the one-piece reinforcement tool 1 was shown in this Embodiment, you may use the reinforcement tool 1 not only as this but.

  As mentioned above, although the manufacturing method of the bearing wall and the bearing wall of this invention were demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part is arbitrary having the same function It can be replaced with the configuration of Moreover, other arbitrary structures and processes may be added to the present invention.
