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 structures formed by using a panel in which a core material made of a phenol 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. .

[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. Furthermore, there was no panel mounting structure that was light, longitudinally stretched, and could be stretched simultaneously in the left and right directions, had good workability, and passed the fire resistance test of JIS-A-1304.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such a drawback, the present invention fixes a plurality of refractory seam plates having a non-combustible sheet formed on a metal seam plate having a substantially inverted T-shaped cross section at a constant pitch. Then, a core material made of a plastic foam and a non-combustible board formed at an end portion is formed between the front surface material and the back surface material, and a fireproof panel having a male part and a female part having a defined structure at the left and right ends is provided with a fireproof cover. It is fixed to all the wall surfaces between the panels with fasteners, a fireproof joint material is formed between the fixed joints, and a fixture is fixed on the fixture between the fireproof panels with the fixture, and furthermore, An object of the present invention is to provide a mounting structure for a fireproof panel, in which an engaging portion of a joint cover is fitted to a locking portion to be integrally formed, and a packing material is formed between the surface of the fireproof panel and the joint cover.

As described above, according to the mounting structure for a fireproof panel according to the present invention, since the structure is such that both ends of the fireproof panel are fixed, the mounting strength is strong. Since the fixing part of the fireproof panel by the fixing tool is completely covered by the joint cover, the head of the fixing tool is not exposed to the outside. Deformation at the time of fixing the fireproof panel is covered by the joint cover, so that no skill is required for construction. It can pass the fireproof structure 1 hour test (JIS-A-1304) of the fireproof structure test by itself. The panel is lighter in weight than ceramic and cement-based fireproof panels that can pass the fireproof structure 1 hour test (JIS-A-1304) of the fireproof structure test by itself, and the workability is dramatically improved. Since the upper and lower pieces of both ends of the fireproof panel are fixed up and down by the fixture, it is possible to reliably prevent a gap from being formed in the joint portion, and to improve fire resistance, airtightness, and waterproofness. If a groove is formed in the fixing part of the fireproof panel,
Since the fixture can be cast into this groove to bury the head of the fixture, even if the fixture is formed in a long shape, the fixture can be fixed after fixing the fireproof panel, and the fixture can be fixed. However, the work can be performed reliably without any problem in the workability whether it is long or short. Since a packing material is formed between the fireproof panel and the joint cover to form a water stoppage, waterproofness, airtightness, fire resistance, and the like are improved. There are features and effects such as.
