Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting an outer wall material of a building.

[0002]

2. Description of the Related Art Panel-shaped outer wall materials are used as outer walls of buildings, such as middle and low-rise buildings and general houses. Conventionally, a horizontally long outer wall material 31 as shown in FIG. 10 is attached to a wall surface of a frame 32 of a new or existing building through a mounting frame 33, and a square outer wall material 34 as shown in FIG. Is similarly attached to the wall surface of the frame 32 via the attachment frame 33. The mounting frame 33 is made of long steel and has an outer surface coated with rust-preventive paint.
As shown in FIG. 3, the mounting plate 36 fixed to the body wall surface 32A by the anchor bolts 35 is fixed by welding or the like and is mounted in a lattice shape.

The outer wall members 31, 34 are fixed to the mounting frame 33 by tapping screws 37 as shown in FIG.

[0004]

By the way, in the above-mentioned conventional example, the error of concrete pouring of the skeleton wall surface 32A,
Due to the large unevenness, it is very troublesome to make the mounting frame 33 vertically flat, that is, to make it flush, and the convex portion 38 of the body wall surface 32A
Chiseling work (see FIG. 12) was required, which required a considerable amount of time and was extremely inefficient. In addition, there is a problem that the rustproof coating of the mounting frame 33 cannot guarantee a long-term rustproof of 30 to 50 years.

Although it is conceivable to use stainless steel as the material of the mounting frame 33, it is expensive and therefore not cost-competitive, and anticorrosion treatment by zinc plating of the steel mounting frame 33 is also conceivable. However, there is a problem that it is not possible to attach zinc dowels because it is long. The present invention has been made in view of the above circumstances, and an object thereof is to easily attach a mounting frame and to perform vertical flattening work to shorten the construction period, and further, to reduce the zinc dope of the mounting frame or the like. It is another object of the present invention to provide a method of attaching an outer wall material that can be rustproofed by plating or electrostatic coating.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, each end portion of a plurality of mounting frames having the same or different lengths is fixed to a skeleton by using cross fittings and mounted in a grid pattern or a grid pattern, and an outer wall material is stretched on the mounting frame. The method of the present invention is characterized in that the cross fitting is attached to an anchor with a screw hole fixed to a skeleton so that its position can be adjusted with respect to an outer wall material mounting surface of the skeleton by a mounting screw.

[0007]

According to the present invention, the threaded anchors are driven at predetermined positions in the body at predetermined intervals in the vertical and horizontal directions, and the cross-shaped, T-shaped and L-shaped metal fittings are attached to the anchors. While mounting with the mounting screws, fix each end of the mounting frame to the cross fittings and arrange them in a grid pattern, then adjust the position with respect to the outer wall material mounting surface of the skeleton with the mounting screws, and then the outer wall of each mounting frame. Make sure the material mounting surface is vertical and flush. In this way, when the work of vertically projecting the mounting frame is completed, the outer wall material is sequentially stretched from the bottom to the upper and left and right directions using tapping screws or the like.
