Description

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

<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 are usually welded to fasteners fixed to the hollow cement board. Alternatively, fixing with bolts is a common method.

<Problems to be Solved by the Invention> However, in order to install a hollow cement board on which a decorative stone board is pasted 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 on. 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 Problems> The present invention has been made in view of the above-mentioned problems, and it involves attaching a separator to the back side of a hollow cement board via a fastener used when attaching a decorative stone board to a hollow cement board. A formwork space is formed between the hollow cement board and the weir board by screwing them together via a separator, and concrete is poured into this formwork space to create an external wall.

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

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

Figure 1 is a schematic plan view of the construction method.
and FIG. 2 are longitudinal sectional views of the same. The hollow cement board 1 is a hollow board made of asbestos cement, etc.
It is lightweight and has excellent fire resistance, earthquake resistance, and design. 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. Surface 1 of this hollow cement board 1
A decorative stone board 2 made of a thick decorative porcelain board, neopalier, etc. is pasted to 1. As a specific means of pasting, as shown in the schematic longitudinal cross-sectional view of FIG. 31 are fitted into the dowel holes 21, 21 formed on the upper and lower end surfaces of the decorative stone board 2. By such a pasting means, the decorative stone slabs 2, 2 are pasted on the surface 11 of the decorative stone board 2 in the form of a potato joint or irregular joint, as shown in the front view of FIG.

A gasket G is filled between the hollow cement plates 1 and 1, and a sealant C is filled between the decorative stone plates 2 to ensure a sealed state.

On the other hand, on the back side 12 of the hollow cement board 1 and on the back side of the fastener 3, a separator mounting fitting 4 shown in FIG. 5 is fixed. The separator mounting bracket 4 has a nut 42 welded to the approximate center of the mounting plate 41, and bolt holes 43 at the four corners of the mounting plate 41, respectively.
43... is perforated. That is, the bolts V, V for fixing the fastener 3 pass through the hollow cement plate 1, the threaded portions v protrude from the bolt holes 43, 43, . . . , and the nuts N are screwed into the threaded portions v and fixed. As shown in FIG. 1, a heat insulating material w can be attached to the back surface 12 of the hollow cement board 1 in advance.

Figure 6 shows the separator mounting brackets 4, 4 as described above.
. . is a rear view showing a state in which the hollow cement board 1 is fixed to the back surface 12. FIG.

In this state, the threaded portion of the separator 5 shown in FIG. 7 is screwed into the nut 42 of the separator mounting bracket 4. This separator 5 is commonly referred to as a round separator, and has screw portions 52, 52 screwed into both ends of a shaft portion 51, respectively.

As mentioned above, connect the threaded portion 52 at one end with the nut 42.
to be screwed together. Then, a cone 6 is attached to the threaded portion 52 at the other end.
A predetermined formwork space O is formed by inserting the cone 6 and bringing the weir plate 7 into contact with the cone 6.
The other threaded part 52 into which the cone 6 is inserted is the weir plate 7.
The form tie 8 is attached in such a way that it penetrates through. A vertical butterfly 81 and a horizontal butterfly 82 are each pressed by a nut n via this form tie 8.

When concrete is poured into the formwork space O, the separator 5 will act as an anchor for the decorative stone board 2 and the hollow cement board 1. Therefore, if concrete is poured into the formwork space O, it will come out almost at the same time. An outer wall body with decorative stone plates 2, 2... pasted on its surface will be constructed.

<Effects of the Invention> As described above, according to the method for constructing an external wall body of the present invention, the hollow cement board with the decorative stone board attached to the surface and the weir board form a formwork space, and the concrete is placed in this formwork space. By pouring the concrete, 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.
