Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior material mounting device for mounting a new exterior material on the surface of a building whose outer wall is formed of an ALC plate.

[0002]

2. Description of the Related Art Renovation work for attaching a new exterior material to the surface of a building in which the outer wall is made of an ALC plate is becoming widespread, and an example is the invention disclosed in Japanese Patent Application Laid-Open No. H11-124980. FIG. 6 shows the above-mentioned conventional example, in which a fixing device for attaching a new exterior material to the outside of the ALC outer wall is directly fixed to a building frame to prevent a load from being applied to the ALC plate. Then, the supporting bracket 10 is inserted into the core removing hole 40 penetrating through the ALC outer wall 3 and fixed to the building frame 1.
0 is fixed, and an exterior material is attached to the vertical waist edge 20 or the horizontal waist edge 30. The support member 10 is a cylindrical body accommodated in an inner member 12 in an outer member 11 so as to be adjustable in length and extendable.
Is provided with a female screw on the inner peripheral surface thereof, and a male screw is provided on the outer peripheral surface of the inner member 12, and both are screw-coupled to be able to expand and contract in the longitudinal direction.

In the above-mentioned conventional example, since the support fitting 10 for attaching a new exterior material is directly fixed to the building frame, no load is applied to the ALC plate constituting the outer wall, so that the ALC plate is not damaged. Although there is an advantage, the following problems arise because the support fitting 10 is formed by connecting the cylindrical body or the screw cylinder and the screw shaft. That is, the support fitting 10 fixes the outer member 11 to the H-shaped steel 1 which is a building body of the building, and fixes the vertical body edge 20 to the inner member 12 by the drill screw 41. The drill screw is attached by drilling and tightening. Since the mounting operation is performed at the same time, the mounting operation involves vibration, and thus the screw connection between the outer member 11 and the inner member 12 may be loosened when the drill screw is mounted, and the mounting height of the support fitting 10 may be different.

Further, since the support member 10 is formed by screwing a cylindrical body, the outer member 11 and the inner member 12 of the support member 10 cannot be rotated after the body edge is attached, so that the length of the support member 10 is reduced. Adjustment is not possible. For this reason, in the above-mentioned conventional example, the horizontal waist edge 30 is
When fixing a new exterior material to the lateral same edge 30 after fixing the support bracket 10, even if it is found that the mounting height of the support bracket 10 is not constant, the trunk edge is not attached without adjusting the height of the support bracket 10. Therefore, when the mounting surface of the body edge is not finished to a fixed height, the exterior material cannot be beautifully mounted.

[0005]

According to the present invention, the outer wall is made of AL.

According to a second aspect of the present invention, in the first aspect of the present invention, the mounting bracket is configured such that an oblong hole provided in a vertical plate of a fixing hardware in a longitudinal direction thereof and a bolt hole formed in a holding plate of a slide hardware match each other. The seat and the bolt are fixed through the holes and the bolt holes. A third aspect of the present invention is the second aspect of the present invention, in which the mounting member has a sliding metal member formed of two holding plates, and a vertical plate of a fixed metal member is slidably incorporated in a gap formed in the holding plate. Features. According to a fourth aspect of the present invention, in the first aspect of the invention, it is preferable that, in the first aspect of the present invention, the body fitting has a front mounting portion on the front side, a center fitting groove on the back side, and the center fitting groove is fixed to the fitting. Features. The fifth of the solving means is the first or fourth of the solving means.
In the above, the body edge metal fitting is characterized in that the horizontal body edge and the vertical body edge are constructed on the same plane using a connection metal fitting.
