It is fixed by b.

As mentioned above, the face material 2 has a shape that matches the frame shape formed by the shaft assembly 1,
For example, if the frame has a rectangular shape, a rectangular face material 2 as shown in the drawing is used, in which a large number of bolt mounting holes 2a are provided in the peripheral edge portion at predetermined intervals. The face material 2
As a material for the above, punching metal is used, which secures the strength necessary for the building structure and is lighter than the one having the same outer shape. The mounting state of the face member 2 is such that the face member 2A arranged on the outside of the two face members 2 is fitted to the inner peripheral side of the shaft assembly 1 and the face member of the face member mounting bracket 3 is mounted. The face material 2B fixed to the material fixing portion 3b by the fixtures 4a and 4b and arranged on the indoor side is fitted into the frame formed by the face material restraining portion 3c, and the face material of the face material fitting 3 is attached. It is fixed to the material fixing portion 3b by fixing tools 4a and 4b. In addition,
The face material 2 is not limited to the punching metal described above, and may be any material having a strength required for a building structure. For example, it may be a simple plate material or a mesh material that does not have many holes of punching metal.

The bolts 4a and nuts 4b can be used as fixtures for fixing the frame assembly 1 and the face material mounting bracket 3 and the face material mounting bracket 3 and the face material, but they have sufficient strength. Any fixing tool having a screw, a rivet, or the like may be used.

However, the outer wall panel 6 is not limited to the one having this specification, and may be another type of outer wall panel.

Next, a method of assembling the bearing wall in which the bearing wall is incorporated into the non-bearing wall will be described. First, as shown in FIG. 4, in the outer wall portion X in which the load bearing wall is to be incorporated, the existing outer wall panel 6 is removed from the frame assembly 1 to expose the frame assembly 1 to the outside (outer wall panel removing step). ).

Next, the face material mounting metal fittings 3 corresponding to the length of the shaft assembly 1 are respectively attached to the inner peripheral surface 1a of the shaft assembly 1, strictly speaking, to the web surface 1a of the lip channel steel, the bolt 4a and the nut 4b. Use to fix (face material mounting bracket mounting process). For the bolts 4a and the nuts 4b, it is preferable to divert the shaft sets to each other or the shaft sets and the foundation are fastened in order to reduce the number of steps, but if the bolts and the like are not previously provided at appropriate positions, Through holes are drilled between the sets to attach the bolts 4a and the nuts 4b, or in the shaft set 1 on the foundation,
Anchor bolts or the like are provided on the foundation to fasten the foundation and the framework 1 on the foundation.

Then, as shown in FIG. 5, first, the face material 2B to be placed on the indoor side is fitted into the frame formed by the face material restraining portion 3c, and the bolt 4a is provided at the peripheral portion thereof.
And the nut 4b fixed to the back surface of the face material fixing portion 3b is used to fix the face material fixing portion 3b, and then the face material 2A to be arranged outside the door is fitted to the inner peripheral side of the frame assembly 1. At the same time, bolts 4a and nuts 4b fixed to the rear surface of the face material fixing portion 3b are used to fix the peripheral portion to the face material fixing portion 3b (face material attaching step). Since a punching metal is used for the face material 2, the load on the operator who mounts the face material 2 is reduced as compared with a mere face material in which a large number of holes are not formed. It

Finally, as shown in FIG. 6, the existing outer wall panel 6 removed in the outer wall panel removing step described above is attached to the frame assembly 1 again by using the predetermined attachment metal fitting 11, and the bearing wall is installed. Completed (outer wall panel restoration process).

In the above-described embodiment of the invention, two face plates 2 are provided in one frame, but the number and thickness of the face plates 2 are required for the construction structure. Can be determined according to the strength of the That is, if high strength is required, two thick face materials 2 are attached, and if not so much strength, a thin face material 2 is used, or one face material 2 is attached to obtain the required strength. It can be secured as appropriate. Further, the face material fitting 3 has two face material fixing portions 3b, and one of which is provided with the face material restraining portion 3c, which is made of a lip channel steel as a shaft assembly. This is because the positional relationship with the ribs is taken into consideration. Therefore, as described above, when the rib 1b of the lip channel steel can be used as the restraint body for restraining the movement of the face material 2 in the wall surface direction, only the face material fixing portion 3b on the indoor side has the face material restraining portion. 3c may be provided, but in the case where the ribs 1b cannot be used as the restraining body due to a large separation distance between the ribs 1b, for example, both face material fixing portions 3 are provided.
The thing which provided the face material restraint part 3c in b is used.

The above description has been made on the case where the lip grooved steel is used as the shaft set 1, but the shape of the shaft set 1 is not limited to this, and for example, as shown in FIG. Even in the outer wall portion Y made of 1A or the like, a face material mounting bracket 3A in which face material fixing portions 3b are provided with face material restraining portions 3c
The structure B of the load bearing wall can be similarly formed by using

The structure of the bearing wall described above can be applied not only to the extension work but also to the new construction work. Further, in the present embodiment, the method of incorporating the load bearing wall in the outer wall portion and the structure of the load bearing wall have been described, but the boundary wall and the partition wall in which the wall panel is fixed to the frame-shaped frame assembly.
