DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PC board used for an outer wall.

[0002]

2. Description of the Related Art Recently, decorative materials such as tiles have been increasingly used for outer walls to improve the aesthetics of buildings. In many cases, a tiled PC board is used for the outer part.

[0003]

However, in the prior art, irregularities are provided on the back surface of a tile or the like, and this is driven into the concrete. However, the difference in the amount of shrinkage of the concrete between the outer surface and the inner surface of the tile or the like, Due to poor adhesion of the tile or the like, the tile or the like may be peeled off from the outer surface.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a decorative material having at least a hollow hole is used as a decorative material such as a tile, and an anchor bolt is inserted into the hollow hole through a blind nut. The present invention proposes a PC board in which the decorative material is integrated with the decorative material, and the anchor portion of the anchor bolt is protruded into the concrete, thereby strengthening the integration between the decorative material and the concrete, and in which the fixture does not appear on the surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a PC board according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a typical example of the PC board A. That is, the PC board A is composed of the main body 1 and the decorative material 2. The main body 1 is made of concrete, reinforcing steel, etc.
It is a board.

The decorative material 2 is a long plate-like body and a short body,
Cement-based, calcium carbonate-based, calcium silicate-based, ceramic, wood chip cement-based, magnesium carbonate-based materials, or glass fibers, whiskers, aramid fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, etc. Extrusion, press molding, injection molding, papermaking, etc. of the mixed material, or weaving various fibers into a cloth or three-dimensional shape and impregnating it with cement, clay, etc. to form a panel Is steam cured and fired. Further, glaze, polishing, painting and the like can be applied to the surface of the decorative material 2. The decorative material 2 is embedded in the decorative surface of the PC board A, and is for improving the design of the PC board A.

[0007] Hollow holes 3 are formed in the decorative material 2 as shown in FIG. The hollow holes 3 are used to make the decorative material 2 into a honeycomb structure, to reduce the weight, and to perform the curing and firing without unevenness. The hollow holes 3 are square, round, oval, triangular, hexagonal,
It has an arbitrary cross-sectional shape such as an octagon.

Reference numeral 4 denotes a blind nut, the back surface 2 of the decorative material 2.
a, and is mounted on the back surface 2a where the hollow hole 3 exists as shown in FIG. The blind nut 4 is for mounting an anchor bolt 5.

Reference numeral 5 denotes an anchor bolt, which is attached to the blind nut 4 of the decorative material 2 and fixes the decorative material 2 to the main body 1. That is, as shown in FIG. 2, the anchor bolt 5 has the head 6 attached to the blind nut 4 and the anchor 7 protrudes from the main body 1 so that the decorative material 2 is not only driven but also firmly fixed. Is made possible. Since the anchor bolt 5 is attached to the blind nut 4 attached to the back surface 2a having the hollow hole 3, the anchor bolt 5 is not exposed at all on the surface of the PC board A and does not impair the appearance.

Here, a method of manufacturing the PC board A will be briefly described. First, an appropriate amount of the blind nut 4 is attached to the cosmetic material 2 according to the size. Next, this blind nut 4
Attach the anchor bolt 5 to. Next, PC 2
It is laid in a mold for forming plate A. Next, concrete is driven into the back surface of the decorative material 2. Next, these are cured and demolded to complete the PC board. Of course, it is also possible to arrange reinforcing bars when driving concrete.

The above is only one embodiment of the PC board A according to the present invention, and it is also possible to use the decorative material 2 as shown in FIGS. 5 (a) to 5 (i) and FIG. . That is, FIGS. 5 (a) to 5 (i) show that small projections 2b are formed on the back surface 2a to increase the contact area with the main body 1 or to provide the decorative surface 2c.
And FIG. 6 shows the decorative material 2 formed not in a plate shape but in a broken stone shape.

[0012]

According to the PC board of the present invention, since the decorative material is fixed not only to the concrete but also to the anchor bolt, it is firmly integrated and does not peel off. In addition, since the anchor bolt is attached to the blind nut mounted on the back surface of the hollow hole of the decorative material, it does not appear on the surface at all and does not impair the aesthetics. There are effects and features such as.
