SUPPORT UNIT OF CONCRETE SLAB FORMWORK

摘要

The present invention provides a support unit of a concrete slab formwork, which comprises: a grid support member placed at the bottom of a ceiling formwork to support a surrounding frame of the ceiling formwork; a wire whose one end is connected to the outermost side of the grid support member and which is guided in a longitudinal direction of a wall formwork placed vertically; and an elevating means placed on the internal side surface at the bottom of the wall formwork to selectively elevate or lower the grid support member as the other end of the wire is wound for winding or releasing of the wire. The present invention reduces the noise from a free fall of an aluminum formwork by preventing the free fall of the aluminum formwork, and also reduces the noise from impact on the formwork due to bonding of pins by minimizing the bonding of pins. The present invention can prevent an issue on constructability and safety, such as a damage to members by a free fall and an accident of workers.
