DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for surface decoration of a broken concrete block.

<Conventional technology> Conventionally, partitioning is performed for ordinary concrete and intermediate breaks in the moving hopper, and decorative material for surface makeup is put in the latter section, moved to the upper surface of the mold, and supplied to the mold. As a conventional method for producing a broken concrete block, a vibrating pressure molding is performed, the mold material is immediately removed from the mold, and after curing and curing, the decorative material portion is broken to obtain a plurality of blocks having a broken surface as a surface.
No. 720 and Tokiko 46-33960.

<Problems to be solved by the invention> Until now, the surface decoration material was integrally molded as a sandwich-shaped intermediate fracture layer sandwiched between ordinary concrete,
In the case where a colored fracture surface is formed on the concrete block surface by splitting and breaking at the intermediate fracture layer after curing and curing, a pigment is added to white cement in a mixer to give a color, or a colored seed stone is mixed. The decorative material for sandwiches obtained in this manner is supplied to a mold from a fixed hopper via a moving hopper and is filled and molded.

Although it has broken after curing and curing, the resulting broken surface is a block surface with no change in coloration.

However, with the recent diversification of concrete products, from the inexpensive one in which the color material is scattered on a part of the surface of the broken block of ordinary concrete, the expensive block which has a variety of colors and colorful surface patterns on the surface For example, there is a wide variety of demands, and it is no longer possible to respond only by the conventional manufacturing method.

It is an object of the present invention to provide a method of making a surface of a fractured concrete block that can obtain a spot pattern or a surface pattern having a partially different color on the fractured surface.

<Means for Solving the Invention> The surface makeup method for a fractured concrete block of the present invention that has achieved the above object is a method of partitioning the inside of a movable hopper into a plurality of chambers in a moving direction, and including an intermediate fracture layer containing a surface decorative material. The base material is put on both sides of the work compartment, and the material is reciprocated from the material receiving position to the upper surface of the formwork, and different materials are fed into the formwork. In the manufacturing method of obtaining a plurality of blocks having the fractured surface as a surface by dividing and breaking the fractured layer, a partition member is inserted from the outside into an intermediate fracture region in the mold when feeding into the mold, A cavity of a surface decorative material is formed, the partition member is extracted, and a foreign material is filled in the cavity, and then vibration, pressure molding, and breaking are performed.

Alternatively, the movable hopper receiving the ordinary concrete from the fixed hopper is moved to the upper surface of the mold, the ordinary concrete is supplied into the mold, and the mold is immediately released after being vibrated and pressed, and then cured and cured to the intermediate position. In the manufacturing method of obtaining a plurality of blocks having a fractured surface as a surface by dividing and breaking in, a cavity is formed at an intermediate fracture position of ordinary concrete by inserting a partition member in a formwork, and a cavity is formed in the cavity thus formed. After the material is filled and subjected to vibration and pressure molding, and after curing and curing, the intermediate fracture position is divided and fractured so that the fracture surface of the decorative material is added to the fracture surface of ordinary concrete.

Further, the partition member is hollow, and it is recommended to fill the hollow portion with a cosmetic material from the hollow portion.

<Function> The present invention is such that a colorful decorative material is partially formed on the surface of a fracture surface of a concrete product after curing and hardening, or a mottled pattern can be obtained.

The invention of claim (1) uses a conventional moving hopper for a breaking block as in the past. When dropping ordinary concrete and decorative material in the hopper into the formwork, place a partition member at the position where the decorative material falls. As a result, a cavity in which the cosmetic material has not entered is formed, and the cavity is subsequently filled with another type of cosmetic material. After the partition member is pulled out of the mold, it is vibrated, pressed and cured, and then divided and broken at the position of the decorative material. Each of the cosmetic materials put in front and behind appears on the fracture surface.

According to the invention of claim (2), the movable hopper is not for a conventional breakable block but is for a normal block, that is, a movable hopper having no internal partition. Therefore, only concrete is usually fed into the formwork. Since the partitioning member is inserted at an intermediate position in the formwork, a cavity is formed when the partitioning member is removed after the ordinary concrete is charged. The cavity is subsequently filled with a cosmetic material, and is integrally formed by applying vibration and pressure, and is divided and broken at an intermediate position, so that the fracture surface of the cosmetic material is also added to the fracture surface.

If the partition member is made of a hollow material, it can be used for a passage of a cosmetic material to be filled later when the partition member is pulled out from the mold.
