Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction board that has excellent heat insulation properties and is extremely easy to assemble.

In general, construction boards are required to be strong, lightweight, fire resistant, and easy to assemble.

Conventionally, various architectural boards made of inorganic materials such as gypsum, glass wool, and rock wool have been provided for this purpose, and methods for manufacturing boards by combining inorganic materials and metal plates have also been proposed. Ta.

However, inorganic material plates have water resistance and
There were problems with robustness, etc., and metal plate-based bodies had problems with heat insulation, ease of assembly, etc.

The present inventor conducted research in search of a metal plate body that is more robust, has excellent heat insulation properties, and is easy to assemble, and has succeeded in obtaining a plate body that satisfies these requirements in the present invention. .

In the present invention, an inorganic foam is sandwiched between upper and lower metal plates, the two metal plates are formed without touching each other, and the right end of the upper metal plate is slightly bent downward.
This is followed by forming a protrusion with a double transverse fold at right angles from the fold, the lower fold extends inward, and its end is bent downward;
The left end of the upper metal plate has a double folded part, followed by a fitting groove into which the fitting protrusion of the other plate fits, and the folded part The lower metal plate is formed by bending downward at the end to form the left side, while the lower metal plate is formed by bending upward at both ends of the foam.

To explain the present invention with reference to FIG. 1, reference numerals 1 and 2 indicate an upper metal plate and a lower metal plate, which are made of elastic metal plates such as iron plate, stainless steel plate, aluminum plate, copper plate, etc., and have smooth surfaces. It is also possible to engrave various patterns. Metal plates are usually 0.2~
The thickness may be about 1.0 mm; if it is too thin, the strength and elasticity will be insufficient, and if it is too thick, the grain size will increase, which is not good. The right end of the upper metal plate 1 becomes a downwardly bent portion 3, and a protrusion 5 having a double folded portion 4 is formed in the horizontal direction from the bent portion 3. From the folded part 4 of the protrusion 5, move directly inward (that is, to the left) from the forward folded part 3.
It is extended to form a lower folded part 6, and the end of the folded part 6 is bent downward to form a right side part 7.

The left end of the upper metal plate 1 forms a double folded part 8, and subsequently a fitting groove 9 is formed with folded parts 10 and 11 so that the fitting protrusion 5 of the other plate just fits. Form into a ⊃ shape. Lower folded part 11
extends to end 12 of foam A and folds downward at end 12 to form left side 13.

On the other hand, the lower metal plate 2 is formed over the entire bottom surface of the foam A, and is bent upward at both ends 14 and 15 of the foam A to form a bottom right side 16 and a bottom left side 17. has been done.

Here, the upper metal plate 1 and the lower metal plate 2 sandwich the foam A and are integrated.
The upper and lower metal plates 1 and 2 do not touch each other. As a result, the heat applied to the upper metal plate 1 is transferred to the foam A.
This prevents heat from being transmitted to the lower metal plate 2, and as a result, the interior of the room is shielded from external heat.

Foam A is formed of an inorganic material, examples of which are as follows.

Example 1 of inorganic foam.

1 Base agent (1) Water glass (No. 3) 2800g (2) (2) Silica powder 150g (3) Kaolin 250g (4) Asbestos powder 70g 2 Foaming agent (1) Colloidal silica (Nissan Chemical) 100g (2) Surfactant (foaming) 1g (Lion Riporan) (3) Water 100g (mix the above and stir to foam) (4) Water glass (No. 3) 100g ((1), (2), (3) Add to the stirred foam and stir,
3 Hardening agent (1) Sodium silicate fluoride Mix and stir 5 to 10% or more of the base agent, the base agent, the foaming agent, and the hardening agent, and immediately pour the mixture onto the upper metal plate 1 that has been turned over using the pouring method. It is manufactured by pouring and molding into the lower metal plate 2, and by bonding both foam surfaces together.

In addition, an example of another foam is shown, and the manufacturing method is Example 1.
is the same as

Example 2 of inorganic foam.

1 Main agent (1) Water glass (No. 3) 2800g (2) (2) Silica powder 150g (3) Kaolin 250g (4) Asbestos powder 70g (5) Obsidian pearlite or shirasu balloon
3 2 Foaming agent Colloidal silica (Nissan Chemical) 150g (2) Surfactant (foaming) 1g (Lion Riporan) (3) Water 150g (4) Water glass (No. 3) 150g 3 Hardening agent (1) Sodium fluoride 8 to 10% of the main ingredient In addition, another example of a foam is shown, but the manufacturing method is Example 1.
is the same as

Example 3 of inorganic foam.

1 Base agent (1) Water glass (No. 3) 2800g (2) (2) Sodium metaborate 70g (3) Silica powder 150g (4) Kaolin 250g (5) Asbestos powder 50g (6) Organic resin (epoxy emulsion )
100～300g (7) Obsidian pearlite or shirasu balloon
3 2 Foaming agent (1) Colloidal silica (Nissan Chemical) 100g (2) Surfactant (foaming) 1g (Lion Riporan) (3) Water 100g (4) Water glass (No. 3) 100g 3 Hardening agent ( 1) Sodium fluoride 8 to 10% or more of the base material, foam A is integrally molded onto the upper metal plate 1 and the lower metal plate 2 by a pouring method, and immediately adhered to the top and bottom. Thus, the architectural board of the present invention is formed.

The plate of the present invention has the above structure,
In use, a long wall board can be assembled by sequentially joining a large number of plates to the left fitting part C and the right fitting part B of another plate.

Next, an example of assembly will be explained with reference to FIGS. 2 to 5. Reference numeral 20 indicates a wooden frame or a metal frame of the structure.

A board is placed at an appropriate position on the wooden frame 20, and a nail 21 is driven into a predetermined position on the extended part of the folded part 11 (Fig. 2) (in the case of a metal frame, it is fixed with screws).
Nails 21 are sufficiently driven into the wooden frame 20 and fixed, and a gasket 22 made of asbestos or inorganic foam is installed at the height of the board excluding the fitting portion. (Figure 3)
Another plate is attached to this, and the fitting part B of the other plate is fitted to the fitting part C (FIG. 4), so that the two are fitted tightly together.
(FIG. 5) At this time, the protrusion 5 firmly enters the fitting groove 9, and the other plate is fixed without nailing the right side. Further, since the plates are brought into elastic contact with each other by the water-repellent inorganic packing 22, they are in complete contact with each other, and air, water, etc. can be completely shut off.

By sequentially joining the plates in this manner, a long wall plate is assembled. Figure 6 shows the combination of three plates, upper metal plates 1, 1, 1.
A beautiful wall is created just by being able to see it.

In this way, the plate body of the present invention is formed without the upper metal plate and the lower metal plate touching each other, so it has excellent heat insulation properties, and can be assembled with just a few nails to improve air permeability and water permeability. It is possible to form a beautiful wall surface without any scratches, and it exhibits an excellent effect when used on the walls of buildings, etc.
