After the frame structure 1 filled with the concrete has been moved to a predetermined place, the concrete which is partially solidified is detached from the frame structure 1 and is caused to solidify still further, thereby obtaining the desired concrete block.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a concrete block, a formwork apparatus, and a method for constructing a concrete block.

[0002]

2. Description of the Related Art Conventionally, concrete blocks mounted on, for example, a river repair work site have conventionally used a bottom mold 21a as shown in FIGS.
The concrete 24 is filled in a mold 21 constituted by detachably connecting side molds 21b which are detachably connected to each other.
It is called the conventional method. ), The concrete block is separated from the concrete block 24 by a hanging member 23 using a crane machine or the like.
The hook 22 buried in the upper surface of the mold is lifted and piled up in the stock yard, carried from this stock yard to the construction site, and the clean finished surface which is in contact with the mold surface of the formwork 21 is different from the surface smoothed by the iron. The concrete block is turned upside down using a heavy machine such as a crane so as to come out.

In the above-mentioned conventional method, if the hook 22 is to be lifted by a crane or the like via the hanging member 23 before the concrete 24 exhibits the predetermined strength,
Because the hook 22 comes off, the concrete block cannot be piled up in the stock yard until the concrete 24 has hardened so that the hook 22 cannot come off. It takes about one week for the hook 22 to harden so that it does not come off.)

[0004] This means that the formwork 21 must be left in place for a week, and the production of the next concrete block using the formwork will take place one week later. Although it is conceivable to use a large number of molds 21 in order to increase the mass productivity of concrete blocks, the cost increases because the number of molds 21 is increased.

[0005] In order to mass-produce the concrete block at a little cost, only a plurality of the bottom dies 21a are prepared, and when the concrete has an appropriate hardness, only the side dies 21b are removed. Although concrete blocks are manufactured by connecting concrete to the formwork 21b, a plurality of bottom dies 21a must be manufactured, which also increases costs.

As described above, the conventional method has a problem that the mass productivity is very poor and the construction period is prolonged.

The present invention provides a method for manufacturing a concrete block, a formwork apparatus, and a method for constructing a concrete block, which solve the above-mentioned problems.
