Composite beam with perforated steel plate connecting pieces and split stud connecting pieces and construction method
The invention provides a composite beam with perforated steel plate connecting pieces and split stud connecting pieces. The composite beam comprises profile steel, a plurality of split stud connecting pieces arranged in the middle of a top flange of the profile steel in the length direction, the two perforated steel plate connecting pieces arranged on the top flange of the profile steel in the length direction and located on the two sides of the split stud connecting pieces correspondingly, top transverse bars, top longitudinal bars and cast-in-place concrete, wherein the top transverse bars and the top longitudinal bars are arranged in a cast-in-place flange plate at the top of the profile steel, and the cast-in-place flange plate at the top of the profile steel is filled with the cast-in-place concrete. The composite beam can further comprise a plurality of transverse penetrating steel bars arranged on the two perforated steel plate connecting pieces in a penetrating mode and bottom longitudinal bars arranged in a cast-in-place flange plate at the bottom of the profile steel. Based on the thought that rigid and flexible shear-resistant connecting pieces are stressed in the composite beam in two stages, the longitudinal shear-resistant effect between the profile steel and the cast-in-place concrete can be improved, and thus the composite beam has the characteristic of being stressed in the two stages and has the advantages of being high in bearing capacity, good in integrity, good in fatigue resistance, capable of improving the crack resistance and durability, convenient and fast to construct and the like.
一种带开孔钢板连接件及分体栓钉连接件的组合梁，包括：型钢；沿长度方向设置于型钢上翼缘正中间的若干分体栓钉连接件；沿长度方向设置于型钢上翼缘且分别位于分体栓钉连接件两侧的两块开孔钢板连接件；设置于型钢顶部现浇翼缘板内的顶部横筋、顶部纵筋以及填充于型钢顶部现浇翼缘板内的现浇混凝土。本发明还可包括：贯通设置于两块开孔钢板连接件的若干横向贯穿钢筋；设置于型钢底部现浇翼缘板内的底部纵筋，本发明基于刚性与柔性抗剪连接件在组合梁中两阶段受力的思想，可提高型钢与现浇混凝土间的纵向抗剪切作用，使组合梁具有两阶段受力特点，且具有承载力高，整体性好，抗疲劳性能好，抗裂和耐久性能提升，施工便捷等的优点。
