Abstract

The invention relates to a formwork device for cantilever structure construction and a construction method thereof. The device comprises at least one pair of supporting rods arranged oppositely, convex extending sections, a plurality of connecting rods, first connecting members and second connecting members; each convex extending section is formed in the manner that one end is embedded in a pouredmain body structure and the other end convexly extends out of the poured main body structure and is located in a to-be-constructed cantilever structure; the opposite two ends of each connecting rod are fixed to the convex extending sections of the corresponding supporting rods; and the first connecting members are transversely fixed on the supporting rods and the bottom surfaces of the connectingrods, and transverse first slots where bottom molds are inserted are formed in the opposite two sides of each first connecting member. According to the formwork device, the supporting rods are pre-embedded in the main structure to serve as subsequent main stress members. The connecting rods and the supporting rods are used as the stress members for transversely hoisting templates so that pouringcan be carried out on the templates to form the cantilever structure.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a form support device and a construction method for cantilever structure construction. Background technique [0002] For the construction of high-altitude cantilevered concrete structures, there is no structural floor under the cantilevered structure, and there is no rooting point for the formwork support frame. [0003] The current conventional practice is to erect the formwork support frame from the ground, and this method requires the erection of a high scaffold, which poses safety risks. Or set up a steel platform on the next floor of the cantilever structure and then build a formwork support frame on the steel platform, but the self-weight of the steel platform itself is relatively large. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art, provide a formwork support device and construction method for can...
