DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite PC board in which a heat insulating material and a hard decorative material are laid on the surface of a main PC board (precast concrete panel).

[0002]

2. Description of the Related Art In general, in a composite PC board in which hard decorative materials such as tiles, bricks, ceramics and natural stones are adhered to the surface of a main PC board, these hard decorative materials are fixed by using mortar as an adhesive. Ordinarily, the surface of a hard decorative material was pierced with a drill or the like, and then was attached to a PC board by brain striking with a fixture such as a screw.

[0003]

However, the composite PC board on which the hard decorative material is mounted with mortar has a problem in durability and earthquake resistance, and causes cracks and peels off from the PC board mainly composed of the hard decorative material. There were drawbacks. Also,
In the case of a composite PC board in which a hard cosmetic is drilled and the fixing tool is brain-strapped, the hard cosmetic material is damaged by a hammer that strikes the hard cosmetic material when mounting the hard cosmetic material, or the fixing tool has a decorative surface. And there were drawbacks such as lack of design.

[0004]

According to the present invention, a heat insulating material is interposed on the surface of a main PC board, a blind nut is mounted in a hollow hole of a hard decorative material, and an L-shaped anchor bolt or the like is inserted through the blind nut. It is a composite PC board that integrates a heat insulating material and a hard decorative material when the main PC board is cured, and has excellent durability, earthquake resistance, heat insulating properties, design properties, and hard surface. The present invention proposes a composite PC board in which a decorative material does not peel off.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A representative example of the plate will be described in detail. Figure 1 shows the composite P
It is explanatory drawing which shows C board, It consists of hard decorative material A, heat insulation material B, and main body C.

[0006] For example, as shown in FIG.
It is formed in a honeycomb shape from a decorative surface 1, a back surface 2, a side wall 3, and a hollow hole 4, and formed in a long plate shape. The hard cosmetic material A is a cement-based, calcium carbonate-based, calcium silicate-based, ceramic-based, wood chip cement-based, magnesium carbonate-based material, or a glass fiber, whisker, aramid fiber, steel fiber, carbon fiber, or various mineral fibers. Extrusion molding, press molding, injection molding, papermaking method, etc. mixed with various aggregates, etc., or various fibers are woven into a cloth shape, three-dimensional shape, and impregnated with cement, clay, etc. It is made of a panel-shaped product that has been subjected to steam curing and firing.

Further, a plurality of hollow holes 4 are formed along the longitudinal direction of the hard decorative material A. The hard decorative material A is formed into a honeycomb structure to save raw materials and reduce weight.
This is to make it possible to perform curing and firing without unevenness. The hollow hole 4 can have any cross-sectional shape such as a square, a round, an ellipse, a triangle, a hexagon, and an octagon.

Reference numeral 5 denotes a blind nut which is mounted on the back surface 2 of the hard decorative material A where the hollow holes 4 are present as shown in FIG. 3, for example, as shown in FIG. Are mounted at a constant pitch. Also, the blind nut 5 is provided with a fixture D described later.
Is attached as shown in FIG. 5, and the hard decorative material A and the main body C are integrated. For this reason, the fixing tool D does not appear on the decorative surface 1 of the hard decorative material A at all, which impairs aesthetics. There is no.

The heat insulating material B is bonded and interposed at least on the surface of the main body C to be described later, and is made of synthetic resin foam such as polyurethane foam, nurate foam, phenol foam, gypsum board, glass wool, sizing board, calcium silicate board, etc. It is made of an inorganic foam or the like or a composite material thereof, and functions as a heat insulating material, a cushioning material, a sound insulating material, a soundproofing material, a fireproofing material, a fireproofing material, a waterproofing material, and a moistureproofing material.

As shown in FIG. 4, for example, the main body C is made of a raw material mainly composed of concrete and mortar, and is usually cured, autoclaved and steam cured, and has a stud material for reinforcement (see FIG. 4). (Not shown), a plurality of upper fittings 6 and lower fittings 7 composed of L-shaped anchor bolts and the like are horizontally embedded, and furthermore, as shown in the figure, a concave portion for saving raw materials and reducing the weight of the main body. 8 is formed.

The hard decorative material A, the heat insulating material B and the main body C are integrated with each other by an L-shaped anchor bolt as shown in FIG.
This is performed by a fixture D made of a steel material, a reinforcing bar, or the like. That is, the heat insulating material B is bonded and interposed in the state in which the fixture D is mounted on the hard decorative material A via the blind nut 5 in advance, and the raw material of the main body C is integrated into the mold at the stage of curing, and integrated with the composite PC board. Is what you do. In addition, the fixture D attached to the blind nut 5 of the hard cosmetic material A is directly extended to the back side to form upper and lower fixtures 6 and 7,
It can also be used for both purposes.

Further, the horizontal joints and the vertical joints formed by the hard decorative materials A are filled with a backup material E and a caulking material F as shown in FIG. 6 to improve waterproofness and airtightness. is there.

Further, as shown in FIG. 7, for example, as shown in FIG. 7, the composite PC boards are welded by welding an upper angle α ₁ and a lower angle α ₂ made of L-shaped steel to a wall base α made of H-shaped steel. And fixing the upper mounting member 6 and the lower angle α _{2 of} the main body C and the lower mounting member 7 and the upper angle α ₁ of the main body C with fixing members β such as bolts. It is attached to the wall base α and connected. In addition, by forming free holes in the upper and lower angles α ₁ and α ₂ , the level of the composite PC board can be adjusted,
It is possible to perform the adjustment of the cross joints.

The horizontal joints and the vertical joints (not shown) formed by connecting the composite PC boards up and down are annular gasket G and fireproof joint H on the back side, backup material E on the front side, and caulking. Material F is to be filled. Further, as a method of connecting the composite PC boards, a well-known connection method such as a panel swivel slab method and a curtain wall method can be used in addition to the method shown in FIG.

What has been described above is one embodiment of the composite PC board according to the present invention, and a hard decorative material A as shown in FIGS. That is, FIG.
(B) is a hard decorative material A in which the shape of the decorative surface 1 is deformed, FIG.
(C) to (e) show a hard decorative material A in which a concave portion is formed on the back surface and a heat insulating material B is backed in advance.

[0016]

As described above, according to the composite PC board of the present invention, since the hard decorative material is attached to the main body by the fixture through the blind nut, the composite PC board is fixed to the surface of the composite PC board. It has a beautiful appearance without any tools. The hard cosmetic material is not damaged or damaged by hammering or the like, and is easy to install. It has excellent durability and earthquake resistance and does not peel off hard decorative materials. The hard cosmetic material can be attached to the main body at any part of the back surface where the hollow holes of the hard cosmetic material exist. A composite PC board with improved heat insulation, durability, earthquake resistance, and design. There are features and effects such as.
