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]

In order to eliminate such drawbacks, the present invention comprises a plurality of fireproof floorboards each having a substantially inverted T-shaped cross section and a metal floorboard having an incombustible sheet formed at a constant pitch. A fire-resistant panel that is fixed and has a core material consisting of plastic foam and non-combustible board formed at the ends between the front and back materials and has male and female parts of the male and female fitting structure on the left and right ends. It is fixed to all wall surfaces between the fireproof tiles with fixtures, and fireproof joint material is formed in the joints between the fixed fireproof panels.
Provided is a structure for mounting a fireproof panel, which is integrally formed by fixing a fixture on the fixing portion between the fireproof panels with the fixture and further fitting the engaging portion of the joint cover to the engaging portion of the fixture. To do.

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 fixing portions at both ends of the fire-resistant panel are vertically fixed by the fixtures, it is possible to reliably prevent the formation of a gap in the joint portion, and improve fire resistance, airtightness, and waterproofness. If a groove is formed in the fixed part of the fire-resistant panel, the fixing tool can be formed so that the head of the fixing tool can be embedded in this groove, so that it can be fixed between the fixing part and the fixture, the upper edge and the fixing part. Prevents the formation of spaces between parts and improves workability, waterproofness, airtightness, fire resistance, and the like. If the breathable member is formed, the decorative surface of the fireproof panel will not be deformed such as swelling or warping for many years. By flocking pile, core material and surface material,
Adhesion with the backing material becomes strong and does not peel off. There are features and effects such as.
