Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a housing member panel that is lightweight and exhibits various excellent performances such as fire resistance and earthquake resistance.

Residential component panels are required to have a variety of excellent properties such as heat insulation, fire resistance, earthquake resistance, sound insulation, and waterproofness, but panels that have all of these properties have been proposed in the past. Things became extremely overlapping and impractical. In addition, some products are advertised as having the above characteristics and achieving mu conversion, but these
Once a fire occurs, it becomes extremely brittle or generates black smoke, making it impossible to achieve the desired fireproof effect. The present invention was made in view of the above-mentioned conventional problems, and its purpose is to create a house that is extremely lightweight and has excellent properties such as heat insulation, fire resistance, sound insulation, waterproofness, and prevention of dew condensation. To provide component panels for use.

That is, in the housing member panel of the present invention, the outer layers on both sides are formed from asbestos slate plates, and on the inside of both asbestos slate plates, polyurethane granules and/or expanded polystyrene granules and asbestos calcium carbonate l! It is made by integrally bonding an inner layer formed by mixing fiber and cement.

Preferably, a reinforcing material such as reinforcing reinforcing bars or metal lath is provided in the inner layer.

Preferred embodiments of the present invention will be described below with reference to the attached drawings.

FIG. 1 shows a housing member panel suitable for an external wall according to a first embodiment of the present invention, and 1-1 indicates asbestos slate boards having a wall thickness of about 3 mm and forming outer layers on both sides. Inside this asbestos slate plate 1-1, finely pulverized cotton calcium carbonate fibrous material with a particle size of 4 to 1.
An inner layer 2 is provided by kneading at a volume ratio of +1:1. Reinforcing reinforcing bars 3 are arranged inside the inner layer 2, the inner layer 2 made of the above mixture is dried and solidified, and the inner layer 2 and the inner and outer layers 1-1 are integrated.

The finely pulverized asbestos calcium carbonate fibrous material used in the above examples is mainly made of lightweight RA acid calcium and asbestos, and contains a small amount of vinyl chloride resin (binder), thickener, and cellulose. A finely pulverized product composed of a mixture, with a particle size of about 1ml1, a particle size of about 3man, and 5+++
They are divided into three types, about +n, and these particles penetrate between the cement grains and bind them together, taking advantage of the properties of cement to prevent cracks in the cement. In addition, asbestos calcium carbonate does not burn or dissolve and does not become brittle even when exposed to direct fire, so when used together with cement, it has excellent fire resistance, heat insulation, heat retention, and smoke prevention. It is also effective.

In addition, the foamed polyurethane granules used in the above examples are extremely lightweight and have excellent sound insulation, heat insulation, and impact resistance.
By mixing it with quality and cement into cement, it is possible to provide housing material panels that are lightweight and have various excellent effects such as heat insulation, fire resistance, and sound insulation.

In the first embodiment, the inner layer 2 is made of a mixture of foamed polyurethane granules, finely pulverized asbestos calcium carbonate fibers, and cement. In two examples, the particle size is between 1 and 4.
Using foamed steel granules of about 111111,
This, finely pulverized asbestos calcium carbonate mN quality, and cement]
It is also possible to form the inner layer 2 by mixing the sludge in a volume ratio of 1:1:1.

In addition, although the reinforcing bars 3 were used as the reinforcing aggregate in the first embodiment, this is an example in which the member panel of the present invention is used as an exterior wall panel, and this member panel is used as a 11-cut panel. In this case, as shown in FIG. 2, metal lath 4 is used as the reinforcing aggregate.

The foamed polystyrene granules used in the second embodiment of the present invention are extremely lightweight and have excellent sound insulation, heat insulation, and impact resistance, similar to the foamed polyurethane granules. In particular, by using fine particles as the expanded polystyrene granules, a dense structure can be obtained, which not only further improves the above-mentioned heat insulation properties, but also improves the adhesion of nails and the like.

In the third embodiment of the present invention, the inner layer 2 is made of foamed polyurethane granules, foamed steel granules, asbestos calcium carbonate fibrous finely ground material, and cement in a ratio of 0.5:0.5.
They are mixed at a volume ratio of 1:1, and in this example as well, it is possible to make a lightweight material panel that takes advantage of the characteristics of foamed polyurethane and foamed polystyrene and has excellent sound insulation, heat insulation, and impact resistance t/ll. It is. As described above, in the residential side panel of the present invention, the outer layers on both sides are formed from asbestos slate plates 1-1, and the inner sides of both asbestos slate plates are coated with polyurethane granules and/or expanded foam granules and asbestos calcium carbonate. ! Since the inner layer 2 formed by mixing fiber and cement is integrally bonded, various effects described below can be achieved.

(1) It has excellent heat insulation and fire resistance, and its thermal conductivity is about 1/6 that of conventional mortar.

(2) When the member panel of the present invention is formed to have the same wall thickness as a concrete panel, its sound insulation properties are almost the same as that of the concrete panel, although its weight is approximately 1/3 that of the concrete panel. Considering that it is generally said that the sound insulation property is proportional to the weight ω, it can be understood how excellent the sound insulation property of the member panel of the present invention is.

(3) The asbestos plate on the inner and outer layers of the panel is waterproof and moisture permeable, and the inner layer is also moisture absorption resistant, making the motorcycle extremely waterproof and water resistant.

(4) The inner layer of the panel has an excellent heat insulating effect, so even if the outside air temperature rises or falls, the temperature difference between the inside of the panel and the inside of the panel does not become large, so no condensation occurs, and therefore it is effective in preventing condensation. I'm soaked in it.

(5) Since the polyurethane granules and expanded polystyrene granules of the inner layer have elasticity and are uniformly mixed with cement, cracks do not occur due to contraction or expansion of the panel.

(6) Asbestos slate plates are adhered to both surfaces of the panel.
・The inside of the groove is filled with inorganic material, so it has excellent insect repellency and corrosion resistance.
