Steel-concrete composite beam containing corrugated connecting pieces and implementation method thereof
The invention discloses a steel-concrete composite beam containing corrugated connecting pieces and an implementation method thereof, and belongs to a steel-concrete composite structure. The steel-concrete composite structure comprises a steel beam, corrugated connecting pieces welded to an upper panel of the steel beam and penetrating steel bars; every two corrugated connecting pieces form a group, and the corrugated connecting pieces are arranged in groups in the longitudinal direction and the transverse direction of an upper panel of the steel beam respectively and distributed in a strip-shaped mode; open holes are formed in the wave crests and the wave troughs of the corrugated connecting pieces, the penetrating steel bars penetrate through the open holes, a layer of the penetrating steel bars are arranged at the wave crests, and a layer of the penetrating steel bars are arranged at the wave troughs in an upper-lower double-layer steel bar arrangement mode; high-performance fiberconcrete is poured on the upper portion of the upper panel of the steel beam and is used for wrapping the corrugated connecting pieces and the penetrating steel bars to form a composite shearing forcepiece. The steel structure is small in welding workload, convenient to construct, high in working efficiency, small in welding residual stress, high in bearing capacity and good in fatigue resistance.
本发明公开了一种含波折形连接件的钢‑混组合梁及其实施方法，属于钢‑混组合结构。该组合结构中包括钢梁，焊接于钢梁上面板的波折形连接件及贯穿钢筋。波折形连接件两个一组，在钢梁上面板的纵、横两个方向上分别成组设置，呈条带状分布。波折形连接件在其波峰与波谷处均设有开孔，贯穿钢筋穿过开孔，波峰处设置一层钢筋，波谷处设置一层钢筋，呈上、下双层钢筋布置形式。钢梁的上面板上部浇筑高性能纤维混凝土，高性能纤维混凝土包裹住波折形连接件与贯穿钢筋，形成复合剪力件。本发明钢结构焊接工作量少，施工便利，工作效率高，焊接残余应力小，承载能力高，抗疲劳性能好。
