DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to construction,
It can be used as an exterior wall material, roof material, ceiling material, floor material, partition material, fire door, etc., and without deformation such as swelling and warping after production, and also has fire resistance, waterproofness, airtightness, workability, The present invention relates to a structure for mounting a fireproof panel having excellent mechanical strength.

[0002]

2. Description of the Related Art In general, a large number of mounting structures formed by using a panel in which a core material made of a phenolic resin foam (phenol foam) is sandwiched between a thin plate-like front surface material and a back surface material have been invented, devised, and put on the market. I have.

[0003]

However, in the panel mounting structure using phenol foam as the core material as described above, the self-adhesiveness of the phenol foam is generally weak, and the surface material, the back surface material, and the core material are not combined. Was inferior in adhesion and easily peeled off. In general, when various types of synthetic resin foams are used as the core material, the mechanical strength of the panel itself is inferior, and, due to the aging of the synthetic resin foam, irregularities may occur or warp on the panel surface. Occasionally it occurred. Furthermore, a reaction gas is generated during the formation of the core material and remains in the core material, or the condensation water during the reaction is maintained in the phenol foam in an amount of about several tens percent by weight. After the installation, moisture changes into steam due to changes in the outside air temperature, etc., and there is no escape route. In some cases, such a problem that the panel is adversely affected with time, such as generation or warping, may occur.
For this reason, there was also a problem that the mounting strength of the panel was reduced. In addition, the connection structure of these panels was complicated and mainly a horizontal structure, so that workability such as around a window was very poor. Furthermore, there was no panel mounting structure that was light, vertically stretched, had good workability, and could pass the fireproof structure test of JIS-A-1304.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such a drawback, the present invention provides a plurality of refractory flooring plates each having a substantially inverted T-shaped cross section and a non-combustible sheet formed on a metal flooring plate at a constant pitch. A fireproof panel with a core material consisting of plastic foam and a non-combustible board formed at the end between the front and back materials, and a real male / female fitting structure at the left and right ends is fixed. Fixing to all the wall surfaces between the boards with fasteners, fireproof joints are formed at the joints between the fixed fireproof panels, and waterproof boards and joint covers are fixed with fasteners on the fixing parts between the fireproof panels In addition, the present invention provides a mounting structure for a fireproof panel in which a recess cover material is formed in a recess of a joint cover and a packing material is formed between the surface of the fireproof panel and the joint cover.
