Prestressed steel reinforced concrete superposed beam composite floor system and construction method
A prestressed steel reinforced concrete superposed beam composite floor system comprises structural columns, prestressed corrugated web steel reinforced concrete superposed beams, precast concrete slabs, a post-pouring concrete layer and secondary beams, the prestressed corrugated web steel reinforced concrete superposed beams are made of asymmetric corrugated web section steel, and common connecting pieces are arranged on upper flange plates of the asymmetric corrugated web section steel. The upper flange plate is provided with an anti-pulling and non-anti-shearing connecting piece; the outer part of the prefabricated concrete shell is provided with a hole channel for penetration of the prestressed tendon along the length direction; a plurality of longitudinal bars and partial iron-based SMA steel bars are arranged at the bottom in parallel; and the stirrups are vertically arranged on the asymmetric corrugated web section steel in the length direction. Flat web steel beam sections are pre-buried in the connecting positions of the structural column sections and the prestressed corrugated web steel reinforced concrete superposed beam sections, the flat web steel beam sections are connected through bolt end plates, and then beam-column and beam-beam connection is achieved through post-pouring of the concrete beam sections. The floor system is reasonable in stress performance, more convenient to construct and excellent in anti-seismic performance and fire resistance.
一种预应力型钢混凝土叠合梁组合楼盖，包括结构柱、预应力波折腹板型钢混凝土叠合梁、预制混凝土板、后浇混凝土层、次梁，预应力波折腹板型钢混凝土叠合梁选用非对称波折腹板型钢，非对称波折腹板型钢上翼缘板布置普通连接件，上翼缘板布置抗拔不抗剪连接件；外部预制混凝土壳，预制混凝土壳内部沿长度方向预留用于穿入预应力筋的孔道；底部平行布置纵筋和部分铁基SMA钢筋若干；箍筋沿长度方向垂直布置于非对称波折腹板型钢。结构柱柱段和预应力波折腹板型钢混凝土叠合梁梁段连接位置预埋平腹板钢梁段，利用螺栓端板连接平腹板钢梁段，再后浇混凝土梁段实现梁‑柱、梁‑梁连接。本发明楼盖受力性能合理、施工更便捷、抗震性能和抗火性能优异。
