Abstract

PROBLEM TO BE SOLVED: To provide a condensation-preventive composite structure unit which is provided with a 2-5mm thin, sturdy, noncombustible, and smokeless board at the surface and also provided with an air heat insulation layer in the inside structure between the board and respective kinds of heat insulation foams, and also which prevents adverse effets resulting from dew drops against the interior surface of a building and eliminates additional construction works to strengthen fireproof, smoke-prevention capacity in the conventional construction method. SOLUTION: A thin, sturdy, and noncombustible surface material having 2-5mm in thickness, an uneven and corrugated material of a foaming raw material chiefly made of a metallic powdery material like alumina or various honeycomb core-shaped heat insulation raw materials are integrally combined to form a composite body as a heat insulation material preventing condensation. Conventional building works are simplified by this composite structure. And this composite structure is excellent in fireproof and smokeprevention properties. In this way, a light and heat-insulative composite structure preventing condentation provided with air heat-insulation layers, can be obtained.

[Industrial applications]

(1) According to the present invention, for example, in the future construction industry that tries to solve the narrowness of the land in the basement, it has a function of preventing dew condensation corresponding to the humidity peculiar to the basement, and the interior surface material is thin and hard and incombustible. It is expected that the demand for the industrial world will be great, as it will be possible to provide a wall surface composite material with good properties.

(2) Since the present invention has a thin and non-combustible board of 2 to 5 millimeters on the surface and an air insulating layer in the internal structure, it is not always necessary to use the chlorofluorocarbon gas or the alternative chlorofluorocarbon. Since it does not require a foam insulation material that uses the heat insulation effect of various solvents, there is no need to worry about filling harmful gases into the room or the basement, and the environment inside the building is purified, so the indoor human body The impact will be good.

(3) The surface material of the present invention is non-combustible and smokeless, but does not emit organic gas because it does not use a harmful flame retardant. In addition to this ultra-safe performance, it also covers and protects various highly ignitable foam materials used in composite structures. If such a dew condensation prevention material with an air insulation structure is widely used, it can be
It is certain that floor fire safety and dew condensation prevention functions will improve dramatically.

2. Description of the Related Art A non-combustible integrally-formed sandwich panel of the present invention and various foamed heat insulating materials provided with an air heat insulating layer have a function of preventing dew condensation while also having fire and smoke prevention properties. There is no one-piece composite structure in the world that can shorten individual works such as fire prevention and smoke prevention. The dew-condensation heat insulating material applied with a light, non-combustible, smokeless panel that is thin, hard, and has a thin surface material is considered to be a thin plate of fired ceramics only for the functionality of noncombustibility and smokelessness, but the ceramic is hard. However, it is fragile and heavy, and the price is high. Even if the same composite structure as the present invention is used, the performance and the price are inferior,
It doesn't seem like a comparison. In addition, cheap gypsum board is weak against moisture, inorganic boards up to now have a thickness of more than 5 millimeters, and have a brittle defect on impact, and such a material does not form a structure having the functionality of the present invention. .

SUMMARY OF THE INVENTION The present invention achieves the purpose of preventing dew condensation and realizes an integral composite structure containing an air insulating layer while ensuring nonflammability and smokelessness on the interior wall surface side, and is lightweight. In addition, the challenge was to realize a structural material that is resistant to humidity.

[Means for Solving the Problems]

(1) In the present invention, glass cloth is used on both sides in order to enhance the robustness of the inorganic material. To further enhance the robustness, one or more layers of glass cloth are loaded on both sides of the board skin to make it thin. The realization of a hard surface material was secured. If necessary, a water repellent such as silicone was applied to this surface material to enhance the humidity resistance.

(2) In order to provide a large amount of an air heat insulating layer between the surface material and the wall surface of the room, the heat insulating foam material is integrally molded into a corrugated and corrugated shape. Further, in consideration of strengthening the brittleness of the heat insulating foam material itself, a type of laminating an aluminum foil on the surface was also considered.

[0008]

The effect of the present invention is to use a non-combustible material which is tough and ultra-thin, so that a composite material having a dew condensation preventing function can be realized while maintaining the fire safety of the interior wall surface.

【The invention's effect】

(1) The integrally-molded composite structural material having a non-combustible surface and a built-in air heat insulating layer obtained according to the present invention does not affect the humidity of the wall surface to the interior wall surface on the indoor side, and the problem of the dew condensation phenomenon does not occur. Settled.

(2) For example, in order to characterize the energy saving effect, various foams are used for the interior wall surface, and the weakness of the conventional construction method that succeeds in improving the airtightness of the interior, that is, the interior wall surface, the ceiling The surface and floor surface are not provided with fire and smoke protection, so the defect that would be a separate construction is compensated for, and there is no need to separately construct work to prevent dew condensation due to humidity. Realized the construction method.
