Abstract

The invention discloses a combined bridge with open pore plate formwork and a construction method of the combined bridge. The combined bridge comprises a combined beam, the open pore plate formwork and a concrete bridge deck, wherein the open pore plate formwork comprises a fold-shaped steel plate and an open pore plate connecting part, the fold-shaped steel plate and the combined beam are welded,the open pore plate connecting part is welded to the fold-shaped steel plate, and multiple open pores are formed in the open pore plate connecting part; the concrete bridge deck comprises a concreteslab and steel bars, the multiple steel bars are cast into the concrete slab and penetrate through the open pores, and the steel bars and the open pore plate connecting part are welded. In the combined bridge, the open pore plate formwork and the upper wing edge of the combined beam are welded and stressed together, and therefore the longitudinal bearing capacity of the bridge is enhanced.

Description

technical field [0001] The invention relates to the technical field of composite bridges, in particular to a composite girder bridge with a perforated plate template. Background technique [0002] Composite structure is a structure made of two or more materials in the same section or each member. Because of its advantages of reasonable material utilization and convenient construction, it is widely used in road, bridge and construction fields. At present, the concrete deck formwork of composite girder bridges is a temporary structure, which is removed after the concrete bridge deck is poured and reaches the corresponding strength requirements, and the materials have not been maximized. Contents of the invention [0003] In view of this, the object of the present invention is to provide a composite girder bridge with perforated plate formwork and its construction method. [0004] In order to achieve the above object, the technical scheme that the present invention takes is:...
