Fabricated prestressed steel-concrete combined frame system and construction method thereof
The invention provides a fabricated prestressed steel-concrete combined frame system and a construction method thereof. The fabricated prestressed steel-concrete combined frame system comprises a steel pipe concrete column, a concrete superposed beam, a prestressed steel strand and a connecting structure; the steel pipe concrete column is provided with a first prestressed hole channel penetrating in the radial direction of the steel pipe concrete column; the concrete superposed beam is vertically connected to the steel pipe concrete column, the concrete superposed beam comprises a precast beam at the lower part and a beam post-pouring layer at the upper part, the precast beam is provided with a second prestressed hole channel which is through along the axial direction of the concrete superposed beam, the first prestressed hole channel coaxially communicate with the second prestressed hole channel, and the beam post-pouring layer comprises an energy-consuming steel bar which extends along the axial direction of the concrete superposed beam; the prestressed steel strand penetrates through and is arranged in the first prestressed hole channel and the second prestressed hole channel so as to pre-tighten the steel pipe concrete column and the concrete superposed beam; the connecting structure is arranged on the steel pipe concrete column, the height of the connecting structure is consistent with that of the energy-consuming steel bar, and the end, close to the steel pipe concrete column, of the energy-consuming steel bar is connected to the connecting structure.
本申请提供了一种装配式预应力钢‑混凝土组合框架体系及其施工方法。本申请提供的装配式预应力钢‑混凝土组合框架体系包括：钢管混凝土柱，具有沿其径向贯通的第一预应力孔道；混凝土叠合梁，垂直连接于钢管混凝土柱；混凝土叠合梁包括下部的预制梁和上部的梁后浇层，预制梁具有沿混凝土叠合梁的轴向贯通的第二预应力孔道，第一预应力孔道和第二预应力孔道同轴导通，梁后浇层包括沿混凝土叠合梁的轴向延伸的耗能钢筋；预应力钢绞线，穿设于第一预应力孔道和第二预应力孔道以预紧钢管混凝土柱和混凝土叠合梁；连接结构，设置于钢管混凝土柱上，连接结构的高度和耗能钢筋的高度一致，耗能钢筋靠近钢管混凝土柱的一端连接于连接结构。
