Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a concrete block that is constructed and installed on a revetment such as a river or a coast, and more particularly to a manufacturing form for the concrete block.
[0002]
[Prior art]
In general, for example, concrete blocks such as concrete wave-dissipating blocks are installed and installed on the revetments such as rivers and coasts, but a large number of concrete blocks are used because the installation area is large.
For this reason, it is more efficient and cost-effective to manufacture directly at the construction site rather than being carried into construction sites such as rivers and coasts.
For this reason, when manufacturing a concrete block, first, if it is a concrete block required at a construction site, for example, a concrete wave-dissipating block, a dedicated formwork having a predetermined shape corresponding to it is prepared.
Then, a sufficient work place is prepared at the construction site, and a concrete wave-dissipating block that requires pouring concrete using the formwork is manufactured.
[0003]
However, this concrete wave-dissipating block is usually a large heavy object of 1 ton / piece or more, the corresponding formwork is also made of iron, has a considerable weight (for example, several tens of kg), and has a large size.
In addition, when producing one type of concrete wave-dissipating block, one type of formwork corresponding to that is always required, and for example, three types of concrete wave-dissipating blocks are used at the construction site. In that case, similarly, three types of formwork are required.
As described above, the work of transporting a large volume formwork to an unsatisfactory site such as road conditions is a very heavy burden in terms of safety, time or cost.
In addition, the number of molds required is the same as the number of concrete wave-dissipating blocks to be used, and many floors are required at the construction site. Of course, the cost of the formwork must be high.
