Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture for fixing two wall materials arranged adjacent to each other.

As a structural form adopted for buildings such as factories and power plants, there is a structural form shown in FIG. In the structural form shown in FIG. 8, a frame is formed by a column material H extending in the vertical direction, an upper girder material K1 spanned above the column material H, and a lower girder material K2 spanned below the column material H. A structure is formed, and an outer wall W is provided so as to surround this structure.

The outer wall W is composed of a plurality of wall materials J. As shown in FIG. The plurality of wall members J are arranged side by side along the upper girder member K1 and the lower girder member K2. It is fixed to the side girder K2.

As shown in FIG. 9, each wall material J includes a plate-like wall material main body B, a first connecting portion C, and a second connecting portion D. As shown in FIG. A first connection portion C is formed on one side edge Ba of both side edges Ba and Bb in the width direction of the wall material body B, and a second connection portion D is formed on the other side edge Bb.

The first connecting portion C has an L shape and includes a first piece Ca and a second piece Cb. The second connecting portion D has a hook shape and includes a third piece Da, a fourth piece Db, and a fifth piece Dc. It faces the width direction of the material body.

As shown in FIG. 9(b), the two wall materials Ja and Jb arranged adjacent to each other have a first connecting portion C of the other wall material Jb between the pieces Da and Dc of one wall material Ja. By being arranged, they are connected.

By the way, in the connection of the wall materials Ja and Jb by the connecting portions C and D described above, the movement of one of the wall materials Ja and Jb away from the other in the direction perpendicular to the plane of the wall material body B cannot be restricted. Therefore, when the distance between the upper and lower fixing positions of the wall materials Ja and Jb (that is, the distance between the upper and lower girders K1 and K2) is large, the wind force F is applied to the outer wall W. , one of the wall materials Ja and Jb separates from the other in the direction perpendicular to the plane of the wall material main body B near the center of the height of the wall materials Ja and Jb. (Fig. 10 shows that the connecting part D of the wall material Ja separates from the connecting part C of the wall material Jb in the perpendicular direction of the wall material body B due to the force F of the wind. This shows a state in which a gap is generated between the wall materials Ja and Jb).
