The male screw member installation structure 1 according to the embodiment of the present invention is used for, for example, a structure such as a building, and as shown in FIG. It is configured to include 9.

The male screw (GIR; glue-in rod) 3 is composed of all metal screw bolts such as steel formed by rolling, for example. The male screw 3 may be composed of a deformed reinforcing bar having a male screw formed at an end portion.

The male screw screw material 5 is also made of a metal such as steel, and the male screw 3 is screwed into the male screw screw material 5. The male screw 3 and the female screw 11 of the male screw screw material 5 are made of, for example, a triangular screw and further made of a metric screw. The male screw screw material 5 may be made of a material such as wood or synthetic resin.

As the member 7, for example, a building member made of plywood can be raised, but as the member 7, another material such as wood (preferably a material in which an uncured adhesive penetrates to some extent) is adopted. May be good. The building member 7 is provided with a hole 13 for a male screw. Then, the male screw screw member 5 to which the male screw 3 is screwed is integrally installed on the building member 7 at a predetermined position and posture. As a result, the male screw 3 is installed in the 13 holes for the male screw at a predetermined position and in a predetermined posture.

The filler 9 is made of, for example, a hardened adhesive, and fills the space 15 between the male screw hole 13 and the male screw 3 of the building member 7.

Since the building member 7 is formed in a rectangular flat plate shape, for example, a flat portion 17 is formed in the building member 7. The male screw hole 13 is provided at a predetermined position of the flat portion 17. Further, the male screw hole 13 extends from the plane of the planar portion 17 in a direction orthogonal to this plane to a predetermined depth.

As shown in FIG. 4 and the like, the male screw screw member 5 is formed in a rectangular flat plate shape smaller than, for example, a building member 7. As a result, the flat portion 19 is also formed on the male screw threaded member 5. The female screw 11 into which the male screw 5 is screwed is provided at a predetermined position on the flat portion 19. Further, the female screw 11 of the male screw screw material 5 to which the male screw 3 is screwed extends from the plane of the planar portion 19 in a direction orthogonal to the plane and penetrates the male screw screw material 5.
