Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of concrete structure construction, and more particularly relates to a formwork hoisting and reinforcing device for a steel reinforced concrete hybrid structure construction beam and a construction method. BACKGROUND

[0002] With the rapid development of cities, high-space large-span steel reinforced concrete structure beams have the advantages of good fire resistance, good local and overall stability, and good seismic performance, and are increasingly applied in urban public buildings. However, such structures are generally used in scenarios with high layer height, large span, and large beam cross-sectional size. In the construction process, a high formwork support system needs to be used, and the construction safety cannot be guaranteed, and the construction difficulty is large.

[0003] In the existing reinforcing construction process of steel reinforced concrete structure beams, the outer formwork of the structure beam is prone to unstable support, and deformation and downward movement may occur during pouring. Moreover, the formwork hoisting and reinforcing construction operation cannot meet the needs of structure beams with different cross-sectional sizes.

This solves the problem of time-consuming and labor-intensive installation and removal of the support system frame and the formwork. However, there are safety hazards for construction personnel during the assembly process of the cantilever structure.

[0005] Patent No. CN201910325099.5, entitled "Construction method of adjustable concrete formwork structure", sets up a formwork mold and a structure bottom formwork to realize the sequential pouring of concrete structures. However, the stability of the support device cannot be guaranteed for structure beams with large sizes, and the formwork hoisting and reinforcing problem cannot be solved for structure beams with different sizes.
