Construction method for dry and wet type composite connecting assembly-type building

Abstract

The invention provides a construction method for a dry and wet type composite connecting assembly-type building. The construction method comprises the following steps that components are prefabricatedin 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, vertical column reinforcements are arranged on the peripheries of the sleeving-connection steel pipes, and the vertical columns are adjusted to be perpendicular and coaxial; the ends of the sleeving-connection steel pipes are positioned in a mutual sleeving-connection mode and are fixedly connected, the vertical column reinforcements are connected in a welded mode or connected through sleeves, and transverse reinforcements are bound; the shear wall inner layers and the shear wall outer layer are hoisted, and the transverse reinforcements of shear walls and the transverse reinforcements of the vertical columns are connected in a welded mode or connected through sleeves; formworks are erected at the joints, the joints of the vertical columns and inner cavities of the shear walls are poured into a whole; meanwhile, the crossbeams are hoisted to be placed on bracket supports, and corner connecting pieces are mounted; the floor slabs are hoisted on the crossbeams; and the steps are sequentially circulated, and composite construction of the assembly-type building is completed. According to the construction methodfor the dry and wet type composite connecting assembly-type building, compressive strength can be improved, and the anti-seismic property is improved.

Description

technical field [0001] The invention relates to an assembled structure, in particular to a dry-wet compound connection assembled structure construction method. Background technique [0002] The prefabricated buildings in the prior art mostly adopt the prefabricated column, beam and wall panel structure, 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 cast-...
