DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface decoration material to be attached to the surface of a concrete product for decorative purposes, a concrete product to which the surface decoration material is mounted, and a method for manufacturing the concrete product.

[0002]

2. Description of the Related Art As a method of manufacturing a concrete product having a surface decoration material attached thereto, for example, as shown in FIG. 6, a cement material 2 such as concrete or mortar is poured into a mold 1 and the cement material 2 is hardened. There is a method in which the decorative materials 3 are placed one by one horizontally on the surface of the cement material 2 and the mold material 2 is released after the cement material 2 is hardened.

[0003]

However, in the above-mentioned manufacturing method, since the decorative materials 3 are put on the cement material 2 one by one, it takes much time and the work efficiency is poor. Therefore, if a plate-shaped surface decoration material in which many decoration materials 3 are integrated with concrete or the like is prepared in advance, and the surface decoration material is put on the cement material 2, the work can be accelerated. However, when the plate-shaped surface decoration material is placed, air enters between the material and the cement material 2, which weakens the adhesive force with the cement material 2 and makes the surface decoration material easily peel off from the cement material 2. was there.

Accordingly, an object of the present invention is to make a surface decoration material of a concrete product less likely to peel off than a cement material.

[0005]

In order to achieve the above object, a surface decorative material for a concrete product according to the first aspect has the following constitution. That is, when a product is placed on a cement material forming the product at the time of molding the product, the air between the cement material and the cement material is allowed to flow out, and a through hole into which a part of the cement material enters is provided.

[0006] According to claim 2, claim 1 is
In the surface decorative material for a concrete product described in (1), joints are provided, and the joints are provided with the through holes.

A concrete product to which the surface decoration material according to claim 3 is attached has the following configuration. That is, the surface decoration material is provided with a through-hole, and when placed on a cement material forming the product at the time of molding the product, the air between the cement material and the cement material flows out from the through-hole, and the cement flows into the through-hole. A surface decoration material, which is made by inserting a part of the material, is attached.

Further, a method of manufacturing a concrete product according to claim 4 has the following configuration. That is, the cement material is poured into the formwork, and the surface decoration material is placed thereon before the cement material is hardened, and the air between the cement material and the through-hole provided in the surface decoration material flows out, In this method, a part of the cement material is introduced into the through hole, and the cement material is cured and then released from the mold.

[0009]

A cement material is poured into a mold, a surface decoration material is placed on the cement material before the cement material hardens, and air between the cement material and the cement material flows out of the through hole. After the cement material is hardened, it is released from the mold.

[0010]

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 10 denotes a mold, into which a cement material 11 is poured. Before the cement material 11 hardens, the plate-like surface decoration material 1 is placed thereon.
Put 2 horizontally. The surface decoration material 12 is made of stone, tile,
Brick / wood / metal / synthetic resin materials, or the same or different kinds of decorative materials integrated with concrete or the like, for example, decorative materials 1 arranged in a staggered pattern as shown in the illustrated example.
2a and the joint portion 12b therebetween, and the entire plate-like portion is bisected at the center. Then, as shown in the figure, first, one surface decoration material 12c is put on the cement material 11, and then the other surface decoration material 12d is put thereon so as to be combined therewith.

Incidentally, such a surface decoration material 12 has a plurality of through holes a in the joint portion 12b. The plurality of through-holes “a” are provided substantially dispersed over the entire surface of the surface decoration material 12.

Therefore, the surface decoration material 1 is placed on the cement material 11.
When the one 12c is placed, the air between the cement material 11 and the cement material 11 flows out not only from the periphery of the surface decoration material 12 but also from the plurality of through holes a. Then, the cement material 11 is introduced into the through hole a, and one of the surface decoration materials 12
Is placed. Similarly, the surface decoration material 1 is placed on the cement material 11.
The other 12d is also placed thereon, and the air between the cement material 11 and the cement material 11 is allowed to flow out not only from the periphery of the surface decoration material 12 but also from the plurality of through holes a to the outside as shown in FIG. The other 12d of the surface decoration material 12 is also placed thereon in the state of being in close contact.

After curing, the mold 10 is opened after the cement material 11 has hardened, and the concrete product shown in FIG. 3 can be obtained. The illustrated concrete product is a concrete block for retaining wall construction. However, the concrete product according to the present invention is not limited to such a concrete block, but can be applied to all concrete products requiring the surface decoration material 12.

The cement material 11 is mainly concrete, but may be mortar. Alternatively, a mortar layer is provided on concrete, and the surface decoration material 12 is attached via the mortar layer. Is also good.

FIG. 4 shows another example of the surface decoration material 12 in which decoration materials 13 having different shapes are integrated with concrete. The joint portion 12b of the surface decoration material 12 is also provided with a plurality of through holes a. Then, it is attached to the surface of a cement material to complete a concrete product as shown in FIG.

As described above, the surface decoration material 12 may be a single sheet which is not divided as in the embodiment shown in FIGS. 4 and 5, or may be divided into two as in the embodiment shown in FIGS. Alternatively, although not shown, it may be divided into three or more parts.

In the illustrated embodiment, the example of the shape of the through hole a provided in the surface decoration material 12 is an elongated hole or a round hole, but the shape of the through hole a is naturally changed to these shapes. The shape is not limited, and various shapes can be considered.

[0019]

According to the present invention, when placing a surface decoration material, air between the cement material and the cement material is released through the through hole,
In addition to increasing the adhesion to the cement material, the cement material enters the through-holes to increase the contact area between the surface decoration material and the cement material, thereby making it difficult for the surface decoration material to peel off from the cement material.

According to the second aspect of the present invention, since the joint portion is provided with the through hole, even if a part of the cement material enters the through hole, there is an advantage that the cement material is not conspicuous even from the outside.
