Abstract

The invention belongs to the technical field of building structures, and provides a bracket overhanging type prestress crimping assembly type concrete frame and a construction method thereof, and the bracket overhanging type prestress crimping assembly type concrete frame comprises a prefabricated column, a composite beam, a composite floor slab and a connecting assembly. The superposed beam comprises a prefabricated beam arranged at the outer end of a bracket of the prefabricated column, a beam post-pouring layer arranged on the prefabricated beam and a bracket upper layer arranged on the bracket. The composite floor slab comprises a slab post-pouring layer and a prefabricated slab which are arranged on the prefabricated beam. The connecting assembly comprises a post-tensioned prestressed reinforcement bundle used for fastening the prefabricated column and the prefabricated beam, a bonding layer arranged between the bracket and the prefabricated beam, and anti-bending energy-dissipation steel bars and anti-shearing steel bars which are arranged on a beam post-pouring layer and the upper layer of the bracket, and the anti-bending energy-dissipation steel bars are connected with anchoring steel bars in the upper layer of the bracket. According to the bracket overhanging type prestress crimping assembly type concrete frame, the assembly type beam-column joints can be conveniently connected with the frame support, the connecting parts of the prefabricated columns and the prefabricated beams are moved out of the core area of the beam-column joints, the stress of the joint parts is smaller, the construction is more convenient, and the quality is easier to guarantee.

Description

technical field [0001] The present application relates to the technical field of building structures, in particular to a corbel outstretched prestressed crimping assembled concrete frame and a construction method thereof. Background technique [0002] The prefabricated concrete frame structure is a frame structure formed by prefabricating, assembling and connecting prefabricated components as the main force-bearing components. [0003] At present, my country's prefabricated concrete frame structure system mainly adopts two connection methods, one is wet connection joints, prefabricated beams and columns are generally disconnected at the joints, and connected by pouring concrete at the construction site. This connection method has large on-site construction workload, intensive joint reinforcement, and difficult to guarantee construction quality; one is the dry connection represented by the prestressed prefabricated concrete crimping node (referred to as PPEFF assembly node) d...
