Bracket overhanging type prestress crimping assembly type concrete frame and construction method thereof
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.
本申请属于建筑结构技术领域，提供一种牛腿外伸型预应力压接装配式混凝土框架及其施工方法，包括预制柱、叠合梁、叠合楼板和连接组件。叠合梁包括设于预制柱的牛腿外端的预制梁、设于预制梁上的梁后浇层和设于牛腿上的牛腿上层；叠合楼板包括设于预制梁上的板后浇层和预制板；连接组件包括用于紧固预制柱和预制梁的后张预应力钢筋束、设于牛腿和预制梁之间的粘结层及设于梁后浇层和牛腿上层的抗弯耗能钢筋和抗剪钢筋，且抗弯耗能钢筋与牛腿上层内的锚固钢筋相连。该牛腿外伸型预应力压接装配式混凝土框架方便装配式梁柱节点与框架支撑相连，且预制柱与预制梁连接部位外移出梁柱节点核心区，其接头部位受力更小、施工更方便、质量更易保障。
