"Effects of the present invention" As is clear from the above explanation, the present invention has the following effects.

(1) 8 L-shaped side formwork boards, 4 partition formwork boards that also serve as scaffolding, 2 L-shaped upper formwork boards, and 4 upper lid formwork boards, Since it is composed of 5 horizontal frame plates, there are 5 types of parts that make up the formwork.
Any type can be used, and the manufacturing cost of the formwork can be reduced.

(2) The partition formwork plates are also used as scaffolding, so work can be done safely.

(3) Since it is configured to be assembled around L-shaped bent parts, it is highly compatible and difficult to deform.

In addition, the shape of the formwork parts is not bulky, making it convenient to transport and handle.

(4) Assembling and demolding can be done with multiple parts assembled, allowing efficient assembly and demolding.
Can do demolding work.

(5) Concrete can be poured and shaped through the upper opening, allowing efficient concrete pouring.

(6) Since the upper cover form board can be removed and leveled with a trowel, unevenness on the block surface caused by air bubbles can be eliminated, and high-quality concrete blocks can therefore be manufactured.
