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 fireproof panel mounting structure in which the engaging portion of the joint cover is fitted to the locking portion of the fixture to be integrally formed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a fireproof panel mounting structure according to the present invention. That is, FIG. 1 is a cross-sectional view showing the mounting structure of the fireproof panel, wherein α is a frame, β is a fixture, A is a fireproof panel, B is a fireproof panel, C is a fireproof joint, and D is a fixture E. And joint cover F
G is a joint, and H is a packing material.

More specifically, as shown in FIG. 2, the fireproof floorboard A is composed of a horizontal fixed piece 1 and a rising piece 2 projecting upward from approximately the center of the fixed piece 1 and has a substantially inverted T-shaped cross section. It is a long sheet made of a metal sheet 3 formed on the sheet and a non-combustible sheet 4 formed on the surface side in the figure of the sheet 3, and a metal sheet is formed by roll forming or extrusion forming. A non-combustible sheet 4 is integrated with the molded sheet 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.

The surface material 5 includes a horizontal surface 6 and side walls 7 which are bent inward at both side edges of the surface 6 inwardly, perpendicularly to the surface 6 or inclined inward and outward. It is composed of a male part 8 and a female part 9 formed at both ends of 7.

The male portion 8 includes a fixed portion 10 having one end of the side wall 7 bent outward and extended, a guide portion 11 having the fixed portion 10 with the front end inclined inward and a front end of the guide portion 11. Further, the projecting contact piece 12 and the tip of the contact piece 12 are

The head of β ₁ is one that was formed so as not to get in the way. For this reason, even if the fixture E is formed in a long shape, the fixture E can be fixed after the fireproof panel B is fixed. When fixing without forming the groove 10a and the groove 15a, if the mounting E is short, the fixing portions 10 and 15 of the fireproof panel B exposed between the mountings E are fixed to the fixing β. However, in the case of using a long one, the fireproof panel B and the fixture E must be fixed at the same time, and there is a problem in workability. Thus, the groove 10

And the side edge of the fire-resistant panel B is made straight to prevent the leakage to the surface side of the female part 9 and improve the dimensional accuracy of the fire-resistant panel B, thereby improving the dimensional accuracy of the working width and the joint. This is for eliminating the gap of the portion G and improving the heat insulating property, airtightness and the like. Further, the reinforcing piece 14, the reinforcing piece 1
