Construction method of composite connection assembled building structure

Abstract

The invention provides a construction method of a composite connecting assembly-type building structure. The construction method comprises the following steps that components are prefabricated in a workshop, wherein the components include vertical columns, crossbeams, floor slabs, shear wall inner layers and shear wall outer layers; joints of the vertical columns are located between the floors, sleeving-connection steel pipes are arranged in the vertical columns and connected through steel pipe connecting pieces, and vertical column reinforcements are arranged on the peripheries of the sleeving-connection steel pipes; the sleeving-connection steel pipes of the vertical columns are hoisted to be connected with the steel pipe connecting pieces in a sleeving mode, and the vertical columns areadjusted to be perpendicular and coaxial; the vertical column reinforcements are connected, and transverse reinforcements are bound; the shear wall inner layers and the shear wall outer layer are hoisted, formworks are erected at the joints, and the joints of the vertical columns and inner cavities of the shear walls are poured into a whole; the crossbeams are hoisted to be placed on bracket supports, and the floor slabs are hoisted on the crossbeams; and the steps are sequentially circulated, and composite construction of an assembly-type building is completed. By adopting the construction method of the composite connecting assembly-type building structure, compressive strength and tensile strength can be improved, stress concentration is reduced, the anti-seismic property is improved, and the influence on the linear construction period of construction is little.

Description

technical field [0001] The invention relates to an assembled structure, in particular to a construction method for a compound-connected assembled building structure. Background technique [0002] The prefabricated buildings in the prior art mostly adopt prefabricated column, beam and wall panel structures, and the prefabricated components are fixedly connected by connectors to form a whole. However, the lateral stiffness of this prefabricated assembly structure in high-rise buildings is insufficient. In the cast-in-place construction technology of structures, the construction method of pouring columns and beams as a whole is adopted, but this construction method has the defects of slow construction progress and poor seismic performance. [0003] Chinese patent document CN106193292A records a steel frame-assembled integral reinforced concrete shear wall structure system, which adopts a steel frame composed of steel columns and steel beams, a prefabricated wall panel and a ca...
