Detailed Description of the Invention

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 refractory slabs formed by forming an inorganic sheet on a metal slat plate having a substantially inverted T-shaped cross section at a constant pitch. Then, a core material made of a plastic foam and an inorganic board formed at the end is formed between the surface material and the back surface material, and the fireproof panel formed in a butt structure is fixed to all the wall surfaces between the fireproof siding boards with a fixture, The joints are integrally formed by fixing the fittings formed with the engaging portions at both ends and the inorganic board in the center of the joint, and further fitting the engaging portions of the joint cover to the engaging portions of the fittings. A fireproof panel mounting structure is provided.

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 composed of a fixture E and a joint cover F, G is a joint portion, 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. A sheet made of a metal sheet 3 formed on the surface of the sheet and an inorganic sheet 4 formed on the surface side in the figure of the sheet 3 are formed by roll molding or extrusion molding of a metal sheet material. The inorganic 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 inorganic sheet 4 is made of, for example, rock wool felt, ceramic wool, glass wool, etc.,
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. The protruding piece 9 is formed by bending the lower end of 7 outward and extending, the groove 10 in which the fixing piece β is recessed in the middle of the protruding piece 9, and the tip of the protruding piece 9 is inclined downward (Fig. Then, the fixed portion 8 is formed by a guide portion 11 bent in an arc shape and bent, and an end edge of the guide portion 11 formed by a reinforcing piece 12 bent inward.

The groove 10 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 is fixed, which will be described later. . 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 10, 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. As described above, by forming the groove 10, it is possible to surely carry out the workability without any problem in the workability regardless of whether the fixture E is long or short.

By forming the guide portion 11 so as to be inclined, as shown in FIG. 1, the inorganic board 2 of the fixture E described later is shown.
It is intended to improve workability by facilitating insertion of 5 and positioning.

When the reinforcing piece 12 is filled with the plastic foam 14 as a raw material of the core 13, the plastic foam 14 prevents the plastic foam 14 from leaking to the surface of the guide portion 11 and the projecting piece 9. It is for improving the dimensional accuracy of the working width by improving the dimensional accuracy of the refractory panel B by making the edge straight, and eliminating the gap of the joint G to improve the heat insulating property, airtightness and the like. . Further, the guide portion 11 and the reinforcing pieces 12 also function as reinforcement of the fireproof panel B itself.

The backing material 16 is mainly the core material 1 as shown in FIG.
