Abstract

The invention discloses a large-span prefabricated corrugated steel web composite beam top and bottom plate synchronous pouring template and a using method thereof. The large-span prefabricated corrugated steel web composite beam top and bottom plate synchronous pouring template comprises a suspended crossbeam (1), a combined internal formwork (2), a reverse-lifting telescopic supporting frame (3), a combined positioning side formwork (4), side formwork fine-tuning screw supports (5), a combined internal formwork bottom plate vibrating hole (6), a combined internal formwork top plate ash discharging hole (7), a telescopic supporting frame (9) and a corrugated pressing plate (16); a plurality of side formwork fine-tuning screw supports (5) are arranged at the bottom of a combined structuretruss of the combined positioning side formwork (4); the reverse-lifting telescopic supporting frame (3) is connected with the combined internal formwork (2) through bolts; the telescopic supporting frame (9) is used for supporting between side plates of the combined internal formwork (2); and the corrugated pressing plate (16) is arranged on the side formwork of the bottom plate of the combined positioning side formwork (4). According to the large-span prefabricated corrugated steel web composite beam top and bottom plate synchronous pouring template, the synchronous pouring of the top and bottom plates of the large-span prefabricated corrugated steel web composite beam and the standardization of the overall prefabrication of the large-span prefabricated corrugated steel web composite beam are achieved.

Description

technical field [0001] The invention relates to the technical field of a long-span corrugated steel web composite beam formwork and its application method, in particular to a large-span prefabricated corrugated steel web composite beam top and bottom slab synchronous pouring formwork and its application method. Background technique [0002] At present, domestic engineering construction is in a transition period. Compared with the traditional construction industry, it has put forward new requirements for environmental protection, green construction, and energy consumption reduction. As a construction general contracting enterprise, how to improve the traditional construction technology and methods to cater to the development trend has become an urgent problem to be solved. As a new bridge structure, corrugated steel web composite steel box girder bridge has low dead weight, saves building materials, and can reduce project cost. At the same time, it can realize the overall pr...
