Description

[Detailed description of the invention] This invention relates to an exterior wall of a building in which concrete is poured inside a plurality of unit decorative boards.

Conventionally, as a wall of a building, for example, JP-A-53-1116
As shown in Publication No. 2, it is known that plywood is lined with a Styrofoam board and adhered to it, these are used as the face plates of a formwork body, and concrete is poured, and the plywood and Styrofoam boards are left as the wall panels of the building. ing.

However, when constructing the exterior wall of a building using the construction method described above, if a unit decorative board with low rigidity, such as a painted metal plate, is used instead of plywood, the pressure during concrete placement will cause the unit to deteriorate. The decorative boards bulge outward and become deformed, and since the concrete poured inside these decorative boards is in close contact with the decorative board through a backing board such as a styrofoam board, only the backing board has an insulating effect. There was a problem that the insulation was insufficient.

This invention solves the above-mentioned problems, and even if unit decorative boards with low rigidity are used, these decorative boards will not be deformed by the pressure of concrete during pouring, and have good heat insulation properties. The purpose is to provide an exterior wall for a building that has a simple structure and is inexpensive.

That is, the exterior wall of a building according to this invention has a unit decorative board with low rigidity interposed between the baseboard and the eave member, and an inner bent part formed on the outer periphery of the plurality of decorative boards perpendicular to the board surface. are joined to each other, and the inner end of the inner bent portion of the decorative board is brought into contact with and supported by a heat insulating and stiffening plate made of a rigid molded product with many holes, thereby creating a heat insulating space between the decorative board and the heat insulating wrinkled stiffening board. concrete is placed closely to the inside of the insulation/stiffening plate.

This idea is constructed as described above, and even if the unit decorative boards have low rigidity, their inner ends are brought into contact with and supported by a heat insulating and stiffening member made of a rigid molded product. It does not deform due to the pressure of heating, and has the insulation effect of both the insulation space between the decorative board and the insulation/stiffening board and the holes in the insulation/stiffening board itself, so there is no insulation space. Compared to , the insulation properties are improved, and the insulation space is provided between the insulation and stiffening plate and the concrete, unlike the case where the weight of the insulation and stiffening plate is heavy and the support structure for the concrete is large-scale. Since the heat insulating/stiffening plate is in close contact with the concrete, the heat insulating/stiffening plate can be securely held in the concrete with a simple support structure, and the heat insulating/stiffening plate and the decorative board are attached to the formwork. Coupled with the fact that the face plate does not need to be removed after concrete is poured, the outer wall of the building can be provided at low cost.

An embodiment of this invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 1 denotes a unit decorative board made of a plurality of metal plates such as iron plates or fiber-reinforced plastic FRP boards with low rigidity. A bent portion 2 is formed, and a groove 3 is formed in the inner and outer directions of this bent portion, that is, in the middle in the thickness direction of the outer wall body.

A plurality of the decorative boards 1 are placed on a baseboard 4 made of a metal plate by being joined in the vertical direction and in the horizontal direction, respectively, and
A needle member 5 made of a metal plate, which constitutes the eaves and the peripheral edge of the roof of the building, is installed on the topmost decorative board 1.

The baseboard 4 and the needle member 5 are formed with inner bent portions 6 and 7 that connect with the inner bent portion 2 of the decorative board 1, and these bent portions 6 and 7 also have the concave grooves 3 of the decorative board 1. A groove 8.9 similar to the above is formed.

A sealing elastic packing 10 made of chloroprene or the like is interposed to span the grooves 3 of the inner bent portions 2 of two adjacent decorative panels 1, and these elastic packings 10 are attached to the peripheral wall of the groove 3. The skirting board 4, which is crimped and is also adjacent to the decorative board 1. Elastic packings 10 are also fitted into the grooves 3, 8, and 9 provided in the inner bent portions 2, 6, and 7 of the needle member 5, and are pressed against the peripheral walls of the grooves 3, 8, and 9.

The inner end of the inner bent portion 2, 6.7 is the heat insulating and stiffening plate 1.
The heat insulating and stiffening plate 11 is made of a large number of calcium silicate plates, porous concrete plates, etc., which have a structure similar to that of an asbestos plate with many holes vertically arranged in parallel, as shown in Fig. 2. It is made of a rigid molded product with holes, and also has a heat insulating and stiffening plate 1.
1 is fixed between the baseboard 4 and the needle member 5.

Then, the inner bent parts 2 and 2 of the two adjacent decorative boards 1
, the inner bent portions 2, 6 and 7 of the baseboard 4 and needle member 5 adjacent to the decorative board 1 are connected through reinforcing iron plates 14 with two nuts 13 screwed onto the outer ends of tension bolts 12, respectively. The inner end of the tension bolt 12 is connected to an inner formwork (not shown).

A concrete wall main body 15 is constructed by pouring fresh concrete between the formwork and the heat insulating/stiffening plate 11 and hardening it.

Note that after the fresh concrete hardens, the inner formwork assembly is removed, and reinforcing bars (steel frames) 16 are buried in the concrete wall earth body 15.

Further, the surfaces of the decorative board 1, baseboard 4, and needle member 5 are similarly coated.

As explained above, according to this invention, the inner end of the inner bent part formed on the outer periphery of the unit decorative board with low rigidity is brought into contact with and supported by the heat insulating and stiffening plate made of a rigid molded product, Since the concrete was placed close to the inside of the stiffening plate, the pressure was supported by the heat insulating and stiffening plate during concrete pouring, so that the decorative plate bulged outward and deformed even if its rigidity was small. In addition, sufficient heat insulation is obtained through the insulation effect of the holes in the insulation/stiffening plate itself, and the insulation effect of the insulation space between the decorative board and the insulation/stiffening plate. By being in close contact with the concrete, the heat insulating and stiffening plate can be reliably held in the concrete with a simple support structure, resulting in the effect of providing an inexpensive building exterior wall.
