Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to an outer peripheral surface of a structure of a building, a structure of a structure, a so-called steel frame base, and fire resistance 1
The present invention relates to a fire-resistant coated sheet useful as a fire-resistant structure having performance of passing time.

[0002]

2. Description of the Related Art Generally, according to the Building Standard Law, the size of a building,
Depending on the application and area, it is necessary to use a wall that has passed the fireproof and fireproof structures. For this reason, it is necessary to form a fireproof coating on the body, and in 1 hour of fireproof coating JIS-A-1304, a normal structure was 35 mm thick rock wool spraying.

[0003]

However, spraying rock wool onto the constructed body and the inner surface of the wall has a poor work efficiency. The spray thickness is not uniform due to the structure, and weak points occur in fire resistance performance. Rock wool is not preferable in terms of safety and hygiene, because the fibers float in the living space during work or in use, resulting in a contaminated environment.
Rock wool easily absorbs moisture and water, and deteriorates the substrate. It peels off over time. Since it is wet spraying, it takes time to dry. There were disadvantages such as.

[0004]

In order to eliminate such drawbacks, the present invention is capable of passing one hour of fire resistance simply by mounting a dry sheet-like covering material on the outer peripheral surface of a structure serving as a body. The present invention proposes a fireproof coated sheet that can be obtained as a fireproof coating.
