Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for constructing an exterior wall of a building, and more specifically, a method for attaching a decorative stone board to a hollow cement board via a fastener, and fixing the fastener. This invention relates to a method for constructing an exterior wall body, in which a separator mounting bracket is fixed with a bolt, a separator is screwed onto the separator mounting bracket, and concrete is poured into a formwork space formed by a weir plate and a hollow cement board supported by the separator. .

(Conventional technology) In order to make a hollow cement board with a decorative stone board attached to it as the exterior wall of a building, special fasteners installed between the shafts of beams and columns and fasteners fixed to the hollow cement board are usually melted together. The most common method is to fix it with bolts or bolts.

<Problem to be solved by the invention> However, in order to install a hollow cement board with a decorative stone board attached to it on an external concrete wall, an anchor is provided in the concrete wall in advance, and the hollow cement board is attached via this anchor. This is to join the fasteners that have been fixed to the

Therefore, when constructing the exterior walls of high-rise buildings, the difficulty of construction and the increased cost of temporary construction such as scaffolding have become major problems.

Means for solving the above problems〉 Shukan 1111 was created in view of the above problems, and it attaches the separator to the back side of the hollow cement board through a fastener used when attaching a decorative stone board to the hollow cement board. A formwork space is formed between the hollow cement board and the weir board via a separator, and concrete is poured into this formwork space to construct the outer wall.

<Function> In this way, the separator is screwed on via the fastener used when pasting the decorative stone slab, the weir plate is supported by this separator, and concrete is poured. Since it is constructed integrally with the outer wall, it is possible to provide a method of constructing the outer wall that is extremely easy to construct and highly safe.

<Example> The method for constructing an outer wall body of the present invention will be explained in detail below based on the drawings.

FIG. 1 is a schematic v'#R plane diagram for explaining the present construction method, and FIG. 21M is a longitudinal sectional view thereof. Hollow cement board 1 is a hollow board made of asbestos cement, etc., and is lightweight, has 11 fire resistance + 47 u, and has an excellent design part. Therefore, in recent years it has been widely used as a material for constructing not only the interior walls of buildings but also the exterior walls. On the surface 11 of this hollow cement board 1, a decorative stone board 2 consisting of a thick decorative chest board, neopalier, etc. is pasted. As a specific means of pasting, as shown in the schematic longitudinal cross-sectional view of FIG.

In addition, a gasket G is installed between the hollow cement board 1.1 and the decorative stone board 2.

On the other hand, on the back side 12 of the hollow cement board l and on the fastener 3
A separator mounting bracket 4 shown in FIG. 5 is fixed to the back surface of the separator. In the separator mounting bracket 4, a nut 42 is welded to approximately the center of the mounting plate 41, and bolt holes 43, 43, . . . are bored in each of the four corners of the mounting plate 41. In other words, the bolt V that fixes the fastener 3 passes through the hollow cement plate 1 and has a threaded portion ■ or bolt hole 4:l, 4:l.
It protrudes from ..., and the nut N is screwed into the threaded portion V to fix it. Incidentally, as shown in FIG. 1, a T-shaped heat insulating material W can be attached to the back surface 12 of the hollow cement board L.

Threaded portions 52 and 52 are threaded onto both ends of the shaft portion 51, respectively.

As described above, the threaded portion 52 at one end is screwed into the nut 42. Then, a cone 6 is inserted into the threaded portion 52 at the other end, and a weir plate 7 is brought into contact with the cone 6, thereby forming a predetermined formwork space 0. Further, the other screw portion 52 into which the cone 6 is inserted passes through the weir plate 7, and the form tie 8 is attached. Through this form tie 8, the vertical grouper 81
And the horizontal grouper 82 is pressed by a person/nut n.

<Effects of the Invention> As described above, according to the method for constructing an external wall body of the present invention, a formwork space is formed using a hollow cement board and a weir board with a decorative stone board pasted on the surface, and concrete is poured into this formwork space. By pouring, one exterior wall is immediately constructed, and it is a construction method that has extremely high construction efficiency and is highly safe even when constructing exterior walls for high-rise buildings.
