Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] Conventional refractory structures constructed by assembling a plate include only inorganic materials such as concrete and ALC, and have a drawback that they lack heat protection and increase cooling and heating costs. there were. Further, in the case of the concrete structure, a coating film is applied on the outer surface to improve the deterioration and waterproof of the reinforcing steel. Furthermore, when an ALC plate or the like was used, it was necessary to apply a fireproof caulking material to the joint. In addition, there was hardly any wall fireproof joint structure using a composite plate in which a synthetic resin and an inorganic lightweight body were used as a core material and both surfaces were sandwiched by metal plates.

[Problems to be solved by the invention]

However, this type of construction is severely frost-damaged, and some of the cement has to be exfoliated and the coating must be repainted every three to five years. There was a disadvantage that scaffolding charges were greatly added.
In addition, concrete and ALC are heat storage materials, which not only increase cooling and heating energy, but also cause severe condensation at joints, destruction of walls, generation of mites and mold, unhealthy environments and the greatest weakness in case of fire There were drawbacks such as

[Means for solving the problem]

In order to eliminate such disadvantages, the present invention provides the surface of the fire-resistant 1-hour structure with heat insulation, weather resistance, workability, design, economy (energy saving), and safety, hygiene and fire protection of the living environment. Attach a heat insulation and fire prevention composite board that can be solved at once,
We propose a fire-resistant wall structure that is beautiful, freezing-free, weather-resistant, and free from condensation, mold and mites, has a comfortable living environment, and is safe and fire-resistant.

〔Example〕

Hereinafter, an embodiment of a wall refractory joint structure according to the present invention will be described in detail with reference to the drawings. Fig. 1 (a), (b)
FIGS. 4A and 4B are explanatory diagrams showing the joints. FIG. 4A shows a case where a cover is provided on the joint, and FIG. 4B shows a case where a cover is not provided on the joint. More specifically, 1 and 1 'are sandwich panels (hereinafter simply referred to as panels), 11 is a frame made of steel, 12 is a floor panel, 13 is a fireproof joint, 15 is a fixture,
20 is a cover. That is, sandwich panel 1
As shown in FIG. 2, a surface made of a thin metal body such as a color steel plate, an aluminum plate, a galvanized steel plate, a quasi-noncombustible material, and a noncombustible material formed integrally with the back materials 2, 6 and the core material This is a composite that can pass, and is integrally provided with a fireproof packing material 14 for heat insulation and fire resistance on the side surface. The surface material 2 is formed of a rectangular decorative surface 3, side walls 4 provided on side edges, and side edges 5 having a U-shaped cross section. The back surface member 6 is formed of a rectangular back surface 7, a side wall 8 provided at the side end for escape of the siding board, and a side edge 9 formed at the end of the side wall 8. 10 is a core material using rock wool, calcium silicate plate, or synthetic resin foam, for example, a polyurethane foam resin, a phenol foam resin, a polyisocyanurate foam resin, a polystyrene foam, a phenol foam resin around pearlite. Coating and heating this,
Foam to be foamed under pressure, and flame retardants,
Flame retardant aids (borax, sodium metaborate, antimony trioxide,
Calcium carbonate, aluminum hydroxide, bentonite,
Perlite grains, shirasu balloon, asbestos, various fibers) are added or laminated, and perlite grains are integrated with a fire-resistant foam paint.
In particular, in order to obtain fire resistance, the panel between the pearlite particles is densely filled in the space between the surface material 2 and the back surface material 6 and the phenol foam containing asbestos fiber is filled in the gaps between the pearlite particles. If it is 1 , 1 ', it will be possible to pass the fire resistant structure test. When a phenol foam-based synthetic resin is used for the core 10, a rust preventive paint is applied to the surface 2 and the back 6 so that the acidic component of the core 10 does not directly contact the surface 2 and the back 6. By applying to the back surface, it is possible to prevent rusting when the front surface material 2 and the back surface material 6 are metal plates. As shown in FIG. 3, the panel 12 has a vertical section 12a and a fixing section 12b and has an inverted T-shaped cross section, and the panels 1 , 1 '
It serves as a guide when mounting, and also serves as an adhesive surface for the fireproof packing material described later. Of course, it also functions as a non-combustible material in a fire resistance test. The refractory joint material 13 is a resilient and adhesive material that passes a joint test for one hour of refractory. 14 is a fireproof packing material, which functions as a stopper when the core material 10 is formed, a fireproof after mounting, or a fireproof heat insulating material.
It serves as a backing plate for the backing materials 2 and 6 and as a guide. Mounting bracket 15
Is a locking portion 16, a fixing hole 17, and a guide claw 18 as shown in FIG.
And riveting holes 19, and are arranged at a predetermined pitch of the frame 11. As shown in FIG. 5, the cover 20 is formed of a decorative surface 21, an engaging piece 22, and an engaging portion 23, is engaged with the fixture 15 under elasticity, and covers the joint 24. In addition,
FIG. 1 (b) shows a wall fireproof joint structure formed without using the cover 20. The back surface of the panel 1 'from the frame 11 is fixed with a valve tight 25. The panel 1 'is constructed as shown in FIG. 6, and the only difference is the shape of the end of the decorative surface 3 of the surface material 2.

Next, the construction method will be briefly described.
It is assumed that a wall refractory joint structure shown in FIG. First, the floor plate 12 is vertically fixed on the frame 11. Next, the panel 1 is brought into contact with the vertical portion 12a of the floor panel 12, fixed to the frame 11 with bolts 26, and then filled with the refractory ground material 13. Next, the fixture 15 is fixed to the surface material 2 with the rivets 27, and then the cover
20 is completed by engagement.

What has been described above is an example of the wall refractory joint structure according to the present invention, which can be configured as shown in FIG. That is, the side of panel 1 ″ has a male and female structure as shown in the figure,
A fireproof jointing material 13 and a fireproof packing material 14 can be interposed at necessary places.

〔The invention's effect〕
