In general, a beam is installed on the ceiling of a building below the ceiling, and to form such a beam, a formwork capable of pouring concrete is installed. The conventional formwork is mainly a plywood material, and most of the demolding formwork is removed when the concrete is hardened. However, such a demolding formwork has problems such as a decrease in work efficiency and damage to the outer surface of the concrete that occurs when the formwork is removed, and thus sloped formwork has been widely used in recent years. The recently used sloped formwork uses a material such as steel, but it is used by welding or bending a thin plate structure for economical efficiency. However, due to such a thin plate structure, there is a problem that sufficient rigidity is not exhibited.
