BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for producing a patterned concrete block.

[0002]

2. Description of the Related Art The surface of a concrete block is monotonous because it is formed on the inner surface of a formwork. In order to improve this, there is also a mass production system in which two concrete blocks are integrally formed, then broken at a crevice, and the broken surface is used as a surface .
Because only by breaking the Hiroshi through concrete it lacks decorative, using only a decorative material in the breaking position, and on the surface of the fracture surface of the decorative material. There are a case where the entire surface of the concrete block has a fractured surface and a case where it has a striped fractured surface.

[0003]

Although concrete blocks have been stretched by the simplicity of the block stacking method, the method of making the above-mentioned fractured surface the surface has been created due to the difficulty of the scrupulousness of the construction surface. The present invention goes one step further and opens a system for mass-producing concrete blocks with different patterns for each piece. The pattern is colored and the shape is different for each one.

[0004]

The method for producing a concrete block with a pattern according to the present invention includes a case where the surface of a concrete block having a pattern is a fractured surface, and a case where the surface of the product is not a fractured surface but one or more surfaces of the product as it is removed. is there. In the case of the former, the decorative material for forming the pattern is dropped to the surface to be broken, and in the case of the latter, the decorative material is dropped to a position to be the product surface. Only drop location is different, a small amount of decorative material (colored mortar, concrete, white, colored cement, different color gravel, granulated Hinto) and a large amount of concrete material, excess and deficiency in parallel to the respective required position The point of dropping is the same.

However, even if it is dropped to a required position in the formwork, the required position is not necessarily limited and limited, and the actually dropped position should be slightly different every time, which is the purpose of the present invention. There is one. Similarly, even if we say that we drop in parallel, there is no difference, and it should be different every time. Therefore, when a pattern appears on the fracture surface,
Even if it appears on the surface of a concrete block that has been removed, it will have a slightly different pattern each time. The pattern fluctuates much more because the concrete material and the decorative material are dropped onto the formwork via the moving hopper. When the two materials dropped to the required position of the moving hopper are dropped into the formwork, they can be varied from the original position by a large or small amount depending on how the materials are dropped. If a plurality of types of cosmetic materials are prepared, not only the color of the pattern of each concrete block can be changed, but also a pattern of a plurality of colors can be made on one concrete block.

In the apparatus for manufacturing a patterned concrete block according to the present invention, in the case of dividing after integral molding, a decorative material chute is integrally formed with a stationary concrete hopper as a stationary hopper for feeding material. What was sent by the extended screw type feeding device and dropped linearly, and the cosmetic material was placed on the circulation conveyor, and the concrete material was sent under the roof while flowing down to the stationary concrete hopper and dropped from the circulation conveyor There are three types of decorative materials that are accumulated at the center of the stationary concrete hopper and the concrete material is accumulated on both sides. The surface of the as-demolding not fracture surface as a device for the patterned is the input opening of the stationary concrete hopper to a plurality, so shekel flat requirements dropped concrete material by adding a feed amount adjusting device, also A chute or hopper with an adjusting device for a cosmetic material is provided at one or a plurality of locations so that a required amount can be dropped to a required position.
