Early-removal formwork system for concreting of constructions comprising beams, plates and columns

摘要

An early-removal formwork system for concreting of constructions comprising beams, plates and columns comprises a plurality of rectangular standard formworks (1), a plurality of early-removal support columns (2), several auxiliary beams (3) and auxiliary formworks. The standard formwork (1) is formed by a face plate (11) and a formwork frame (12), and the formwork frame (12) is provided with L-shaped corners (121) at four corners. The early-removal support column (2) is formed by an upper support column (21) and a lower support column (22) in telescopic connection, a rectangular top plate (23) is disposed at the top end of the upper support column (21), one corner of the top plate (23) fits an internal corner of any L-shaped corner (121) on the formwork frame (12). An unloading mechanism (24) is connected between the upper support column (21) and the lower support column (22). An early removal mechanism (25) for early removal of the standard formwork (1) is disposed on the upper support column (21), short support posts (251) for supporting the formwork frame (12) are disposed at four corners of the early removal mechanism (25), and a structure for preventing the formwork frame (12) from slipping out is formed between the short support post (251) and the L-shaped corner (121). The formwork frame (12), the auxiliary formwork, the auxiliary beam (3), and a suspension beam (4) may be all in a removal combined structure. In the formwork system, transport and storage of the formwork are convenient, and manufacturing cost is reduced.
