However, as mentioned above, with weak formwork boards such as those made of cardboard, the upper edges of the formwork board may be damaged or bent during formwork assembly work or concrete pouring, resulting in The disadvantage is that it may not be possible to construct the legal framework. In addition, when constructing concrete legal frameworks, etc., the dimensions of the legal framework vary depending on the site, and therefore various sizes of core-shaped formwork are required. . In this case, the formwork board is made of cardboard, so it is easy to form it into a size that suits the site, but the Bata material is made of steel, so it must be machined to the size required on site. It would be very troublesome to do so.

As explained above, the present invention uses a lightweight material with low strength to create a simple formwork, improves the reinforcing butter material used for assembly, and improves the upper edge of the formwork formed into a core shape. In addition, the length of the batten material can be adjusted freely by fitting the ducting rod and the sliding rod in a slidable manner, so there is no possibility of damage during formwork construction. It protects the upper edge of the formwork, which is prone to damage, and allows for reliable construction.Even when the size of the core-shaped formwork used varies
It can be adapted by adjusting the length of the batting material, and therefore workability is good, materials can be saved, and formwork construction efficiency can be improved.
