Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a fire protection siding for armored horizontal covering such as buildings and structures.

(Prior art) Conventionally, as a fire protection siding board for a building or a structure, a convex male connecting portion is formed on one side edge of a surface material such as a horizontally long metal plate, and a concave female connecting portion is formed on the other side edge. A fire-resistant structure is formed by filling a fire-resistant core material to a required thickness on the back surface of the surface material and fitting the male / female-type connecting portion to the fire-resistant structure. It is publicly known as disclosed in Japanese Patent Application Laid-Open Publication No. H10-260,000.

(Problems to be solved by the invention) However, in the above-mentioned conventional technology, in particular, FIG.

FIG. 1 (m) shows a structure in which a convex fitting portion having a flat cross section of a male connecting portion is fitted into a concave fitting portion having a substantially horizontal U-shaped cross section of the female connecting portion. Therefore, in the former case, looseness occurs in the fitting portion due to the difference in the shape of the uneven fitting portion, and the connection between the male and female connecting portions is insufficient and uncertain, and the heat insulation and fire protection of the portion In addition, there is a problem that the strength is remarkably reduced, and that water cannot be reliably prevented from flowing in the portion. In the latter case, the fitting portion is thinner than the former, so that the male and female portions are further increased. There is a problem that the heat insulation and fire resistance and the strength of the mold connecting portion are inferior.
