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. Furthermore, there was no panel mounting structure that was light, could be stretched vertically, could be stretched in the left-right direction, had good workability, and could pass the fireproof structure test of JIS-A-1304.

[0004]

In order to eliminate such drawbacks, the present invention fixes a plurality of fire resistant pavement plates having a non-combustible sheet formed on a metal pavement plate having a substantially inverted T-shaped cross section at a constant pitch. Then, a core material made of plastic foam and a non-combustible board formed at the end is formed between the surface material and the back surface material, and a mating groove is formed at the end to form a butt-shaped fireproof panel between the fireproof tile boards. Fix it to all the wall surfaces of the fixture with fixtures, form a non-combustible board between the fitting grooves, and fix the fixtures that have locking parts on both ends on the non-combustible board of the joint part, and further to the locking parts of the fixture. It is intended to provide a mounting structure for a fireproof panel which is integrally formed by fitting an engaging portion of a joint cover.

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 refractory panel, where α is a skeleton, β is a fixing tool, β ₁ is a head of the fixing tool β, A
Is a fire-resistant floor board, B is a fire-resistant panel, C is a fire-resistant joint material, D is a cover material including a fixture E and a joint cover F, and G is a joint portion.

More specifically, as shown in FIG. 2, the fireproof seam plate A is composed of a fixed piece 1 having a horizontal surface and a rising piece 2 having a substantially central portion of the fixed piece 1 projecting upward. And a non-combustible sheet 4 formed on the front side in the drawing of the metal plate 3, and a metal plate formed by roll forming or extrusion molding. The non-combustible sheet 4 is integrated with the 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 noncombustible sheet 4 is made of, for example, rock wool felt, ceramic wool, glass wool, or the like.
Prevent gaps from being formed in joints G at the time of the fireproof structure 1 hour test of the fireproof structure test of JIS-A-1304 (fireproof 30 minutes, fireproof 1 hour, fireproof 2 hours for each fireproof performance) It blocks the invasion of flame and is useful mainly as a function for refractory materials, airtight materials, and the like.

As shown in FIG. 3, the refractory panel B has a hat-shaped cross section and a long surface material 5;
Core material 13 having a hat-shaped cross section formed on the back surface of
3 is formed in a sandwich structure from the back material 16 covering at least the back surface in the longitudinal direction.

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. A fitting groove 9 in which the lower end of 7 is bent inward in a substantially U-shape, a projecting piece 10 in which the lower edge of the mating groove 9 is projected outward and extended, and a fixture β is housed in the middle of the projecting piece 10. Groove 11 that is recessed as much as possible
And a reinforcing piece 12 in which the tip of the protruding piece 10 is bent inward,
The guide portion 8 in which the tip of the protruding piece 10 is inclined and bent downward
It is formed of a fixed part 8 composed of a and a.

The guide portion 8a is formed so as to be inclined so that the refractory joint material C, which will be described later, can be easily inserted as shown in FIG. 1 and the positioning can be simplified to improve the workability. Of course, it may be formed to be inclined in an arc shape.

As shown in FIG. 1, the fitting groove 9 is a groove for fixing the incombustible board 24, which will be described later, between the fireproof panels B, strengthens the fixing force of the incombustible board 24, and joints between the fireproof panels B. It dramatically improves the fire resistance of G.

The groove 11 is formed by accommodating the fixture β so that the head β _{1 of the} fixture β to which the fireproof panel B is fixed does not get in the way when the fixture E described later is fixed. . 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. In addition, when fixing without forming the groove 11, if the fixture E is short, the fixing portion 8 of the fireproof panel B exposed between the fixtures E may be fixed by the fixture β. In the case of using a lengthy one, the fireproof panel B and the fixture E must be fixed at the same time, which causes a problem in workability. By forming the groove 11 in this manner, the mounting tool E can be reliably installed without any problem in workability regardless of whether it is long or short.

When the reinforcing piece 12 is filled with the plastic foam 14 which is the raw material of the core material 13, the plastic foam 14 is prevented from leaking to the guide portion 8a and the surface side of the projecting piece 10 and the fireproof panel B side. By making the edges straight and improving the dimensional accuracy of the fireproof panel B,
This is for improving the dimensional accuracy of the working width, and for eliminating the gap between the joints G to improve the heat insulating property, airtightness, and the like.
