Description

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 using phenol foam as the core material as described above, the self-adhesiveness of the phenol foam is generally weak, and the adhesiveness between the surface material, the back surface material and the core material is generally low. 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. In addition, it is light, vertical and has good workability.
There was no panel mounting structure that could pass the fireproof structure test of SA-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 the entire wall surface between the boards with a fixture, fireproof joint material is formed at the joint between the fixed fireproof panels, and the fixture is fixed with the fixture on the fixing portion between the fireproof panels,
Further, the present invention provides a mounting structure for a fireproof panel in which an engaging portion of a joint cover is fitted to a locking portion of a fitting to be integrally formed, and a packing material is formed between the surface of the fireproof panel and the joint cover. Is what you do.

It is a long sheet made of a metal floor plate 3 formed in the above and a non-combustible sheet 4 formed on the front side in the drawing of the floor plate 3, and the metal plate is formed by roll forming or extrusion forming. The non-combustible sheet 4 is integrated with the molded floor plate 3 with an adhesive or the like. 1a is a tongue piece for enhancing waterproofness and preventing danger.

As shown in FIG. 1, the fireproof panel A is formed on the back surface of the joint G of the fireproof panel B to prevent infiltration of rainwater, flame, etc. from the space between the fireproof panels B to the frame α side. It functions as a guide or the like when fixing the panel B.

The non-combustible sheet 4 is a sheet made of inorganic fibers, for example, rock wool felt, ceramic wool, glass wool, or the like.

As shown in FIG. 3, the fireproof panel B has a long surface material 5 and a core material 20 formed on the back surface of the surface material 5.
And a back material 23 covering at least the back surface in the longitudinal direction of the core material 20 to form a sandwich structure.
