Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention adds insulation, cosmetic properties, durability, air circulation function, and dew condensation resistance to buildings and structures that require one hour of fire resistance. It concerns wall fireproof construction.

[Prior Art] Conventional fireproof structures are made only of inorganic materials such as concrete and ALC, and have the drawbacks of lacking heat protection and increasing heating and cooling costs. In addition, a coating was applied to the outer surface of concrete structures to prevent deterioration of the reinforcing steel and to prevent water from building up.

[Problem to be solved by the invention]

However, this type of structure is subject to severe frost damage, causing some of the cement to peel off and the decorative surfaces to be painted for three to three years.
It had to be repainted every five years, and if the cost was high, there was a disadvantage that a large amount of scaffolding was required in addition to the paint raw materials. In addition, since concrete and ALC act as heat storage materials, they not only require increased energy for heating and cooling, but also have disadvantages such as condensation, which causes destruction of walls, the growth of mites and mold, and an unhealthy environment. Of course, in order to pass the one-hour fire resistance test, it had to be made considerably thicker.

[Failure to solve the problem]

In order to eliminate these drawbacks, the present invention provides insulation on the surface of the building frame that can solve the problems of heat insulation, weather resistance, workability, design, economy (energy saving), and safety, hygiene, and fire prevention of the living environment all at once. A fire-resistant composite board is installed, and a calcium silicate fire-resistant covering board structure is installed on the back of the frame, making it beautiful and free from frost damage. This project proposes a wall fire-resistant structure that is safe and has a fire resistance of one hour in a safe living environment.

To explain further, it is a wall fireproof structure in which the panel 1 and the lining are attached to the front side of the frame 15, and the plate body 14 is attached to the back side. Here, to explain each constituent material in detail, the panel has a cross section shown in FIGS. 2(a) to (q), for example, and has a hat-shaped cross section and a long metal surface material 2 ( (hereinafter simply referred to as the surface A), the nailing part 3, a heat insulating material 4 having a cross-sectional shape of a hat attached to the back surface of the surface material 2, and a metal back material 5 covering at least the back surface in the longitudinal direction of the heat insulating material 4. (hereinafter simply referred to as the backing material) into a sandwich structure. To explain further, the surface material 2 and the back material 5 are metal materials, such as A 1 , Fe, Cu, stainless steel, aluminum/zinc alloy plated steel sheet, colored steel sheet, clad steel sheet, vibration damping steel sheet (sandwich steel sheet), etc. It is molded by press working, extrusion molding, and roll forming.

In addition, the length of the surface material 2 is 4000 to 1000100O0
The width (width of the decorative surface 2a) is approximately 400 to 900 ml11, the total width is approximately 450 to 1100 mm, and the thickness of the heat insulating material 4 is approximately 10 to 150 mm. In addition, the heat insulating material 4 is mainly made of synthetic resin foam, such as polyurethane foam resin, phenol foam resin, polyisocyanurate foam resin, polystyrene foam, or pearlite coated with phenol foam resin. Foam is foamed by heating and pressurizing, and flame retardants and flame retardant aids (borax, sodium metaborate, antimony trioxide, calcium carbonate, aluminum hydroxide, Pen 1~
It is made by adding or laminating one or more of the following: nylon, pearlite grains, shirasu balloons, asbestos, and various fibers. In particular, if you want to obtain fire resistance, pearlite particles are densely filled in the space between the surface material 2 and the back material 5.
If we were to create an integrated panel by filling the voids between particles of Barley 1 with phenol foam containing asbestos fibers,
It will be able to pass the fireproof structure test. In addition, the insulation material 4
When using phenol foam-based synthetic resin,
By applying anti-corrosion paint to the back surfaces of the surface material 2 and back surface material 5 so that the acidic components of the heat insulating material 4 do not come into direct contact with the surface material 2 and back surface material 5, the surface material 2 and back surface material 5 are made of metal plates.
