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 decorative materials such as tiles and bricks are adhered to the surface of a main PC board, the decorative material may be a mortar fixed as an adhesive or the surface of the decorative material. Was usually drilled and attached to the brain with a fastener such as a screw.

[0003]

However, the composite PC board to which the decorative material is bonded by mortar has problems in durability and earthquake resistance, and has a defect of causing cracks and peeling. In addition, in the case of a composite PC board in which a fixing material is brain-strapped by drilling a cosmetic material, the cosmetic material may be damaged by a hammer striking the brain when the cosmetic material is attached, or the fixing device may be damaged on the surface decorative surface. There are drawbacks such as lack of design because they appear.

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.

That is, the hard decorative material A has a long plate shape as shown in FIG. 2, for example, and has a plurality of hollow holes 1 formed along the longitudinal direction. The hard decorative material A is obtained by extruding, drying, and firing a raw material mainly composed of clay, and has any of the properties of porcelain, ceramics, and stoneware depending on the firing temperature. Further, the hollow hole 1 is formed to reduce the weight of the hard decorative material A and to save raw materials, and further functions as a fixing hole into which a fitting D described later is inserted.

The heat insulating material B is bonded and interposed at least on the surface of the main body C 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. Made of inorganic foam, etc., or its composite material, heat insulating material, cushioning material, sound insulating material,
It functions as a soundproofing material, fireproofing material, fireproofing material, waterproofing material, and moistureproofing material.

As shown in FIG. 3, for example, the main body C is formed by driving a raw material mainly composed of concrete and mortar into a mold and performing normal curing, autoclave curing, and steam curing. (Not shown), upper fixing metal 2 and lower fixing metal 3 made of an L-shaped anchor board or the like
A plurality of recesses 4 are formed on the back side to save raw materials and reduce the weight of the main body C as shown in the figure.

Further, as shown in FIGS. 4 and 5, the hard decorative material A is attached to the main body C by inserting a fixture D shown in FIG. 6 into the hollow hole 1 and fixing a fixture β such as an anchor bolt. It is fixed through. That is, as shown in FIG. 6, the attachment D is made of a columnar steel material, an extruded material such as aluminum, or the like, and has a hole 5 formed at a substantially central portion in the longitudinal direction.

[0010] The hard decorative material A is previously attached to the fixture D.
Is inserted into the hollow hole 1 and made of an L-shaped anchor bolt and the like, and with the lower fixing metal fittings 2 and 3 inserted into the hole 5, the heat insulating material B is interposed, and the raw material of the main body C is driven into the mold to cure. The composite PC board A can also be integrated at the stage of performing.

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. 4 to improve waterproofness and airtightness. is there.

Further, as shown in FIG. 7, for example, as shown in FIG. 7, an L-shaped upper angle α ₁ and a lower angle α ₂ are fixed to the H-shaped steel base α by welding, bolts, etc. The lower fixing bracket 3 and the upper angle α _{1 of} the main body C, and the upper fixing bracket 2 and the lower angle α ₂ are fixed to the steel base α by fixing them with fixing members α ₃ such as bolts. The upper and lower angles α ₁ , α
_By making a free hole in ₂ , adjust the level with the steel frame base α and the upper and lower angles α ₁ , α ₂ ,
The horizontal and vertical joints can be adjusted by the upper and lower fixing brackets 2 and 3 with the upper and lower angles α ₁ and α ₂ and the main body C.

The horizontal joints and the vertical joints (not shown) formed by connecting the composite PC boards to each other up and down are annular gaskets G and fire-resistant joints H on the back side, backup materials 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 an embodiment of the composite PC board according to the present invention, which is a hard decorative material A as shown in FIGS. 8 (a) to 8 (d), and FIGS. 9 (a) to 9 (d). FIG. 10 (a),
An attachment D as shown in FIG. 8 (a) and 8 (b) show a hard decorative material A in which the shape of the decorative surface is deformed, and FIGS. 8 (c) and 8 (d) show a hard decorative material in which a concave portion is formed on the back surface and a heat insulating material B is backed in advance. A. 9 (a) to 9 (d) show mounting fixtures D having deformed shapes.
In particular, FIG. 9 (d) shows a fixture D in which the periphery of the fixture D is covered with a soft packing 6, and FIG. The formed fixture D, FIG. 10 (b), is formed by connecting two columnar steel materials at one end and forming a U-shape. It is a fixture D used to attach the.

[0015]

As described above, according to the composite PC board of the present invention, a beautiful appearance is obtained without any fixtures appearing on the surface of the composite PC board. Since the hard decorative material is fixed via the fixture, the hard decorative material can be easily attached without damage or damage to the hard decorative material due to hammering, etc. In addition, the hard decorative material is excellent in durability and earthquake resistance and peels off There is no. Since the fixture is inserted into the hollow hole of the hard decorative material to attach the hard decorative material, any portion of the hard decorative material in the width direction can be fixed. It is easy to replace when the hard decorative material is broken.
A composite PC board with improved heat insulation, durability, earthquake resistance, and design. There are features and effects such as.
