2. Description of the Related Art Conventionally, concrete casting formwork includes:
Concrete formwork reinforced by nailing wooden piers to the back of plywood has been widely used. However, the concrete formwork with this wooden pier is easy to bend and the dimensional accuracy is low, so when assembling the formwork, misalignment is likely to occur between the adjacent formwork, concrete concrete construction method, concrete There was a problem with the method of attaching the interior cloth directly to the casting surface. In addition, concrete forms are damaged more after one or two or three uses, and the entire form must be discarded, resulting in large waste of wood resources.
Particularly in recent years, minimization of huge construction waste materials and recycling of waste materials have become indispensable social demands.
