Fabricated corrugated steel web-UHPC (Ultra High Performance Concrete) composite beam
The invention provides a fabricated corrugated steel web-UHPC (Ultra High Performance Concrete) composite beam. The fabricated corrugated steel web-UHPC composite beam comprises UHPC plates, steel beams and bolt connecting pieces, a notch is formed in the UHPC board in the length direction of the UHPC board. The steel beam comprises an upper flange steel plate, a corrugated steel web and a lower flange steel plate; the UHPC plate is arranged on the top surface of the upper flange steel plate, a connecting hole is formed in the upper flange steel plate in the direction of the central axis of the steel beam, a notch in the UHPC plate corresponds to the connecting hole in the upper flange steel plate in position, and a cast-in-place groove is formed between the inner surface of the notch and the top surface of the upper flange steel plate; the bolt connecting pieces are fixedly connected with the upper flange steel plate through the connecting holes; the bolt connecting piece comprises a screw rod, a nut, a steel gasket and a circular hollow sleeve; the anchoring end of the screw rod is arranged in the cast-in-place groove above the connecting hole, and the cast-in-place groove is filled with a pouring material. According to the invention, detachable replacement of the composite beam member is realized; the performance of the concrete slab is improved; the buckling stability of the steel beam web is enhanced, the construction procedure of the steel-concrete composite beam is simplified, and the construction speed can be increased.
本发明提供了一种装配式波形钢腹板‑UHPC组合梁，其包括UHPC板、钢梁和螺栓连接件；UHPC板沿其长度方向开设有槽口；钢梁包括上翼缘钢板、波形钢腹板以及下翼缘钢板；UHPC板置于上翼缘钢板的顶面上，上翼缘钢板沿钢梁中心轴线方向设有连接孔，UHPC板上的槽口与上翼缘钢板上的连接孔位置相对应，槽口的内表面与上翼缘钢板的顶面之间形成现浇槽；螺栓连接件通过连接孔与上翼缘钢板固定相连；螺栓连接件包括螺杆、螺母、钢制垫片和圆形空心套筒；螺杆的锚固端置于连接孔上方的现浇槽内，现浇槽内填充有浇筑材料。本发明实现了组合梁构件的可拆卸更换；提高了混凝土板的性能；增强了钢梁腹板的屈曲稳定性，简化了钢‑混凝土组合梁的施工工序，可提高建造速度。
