Bolting-welding mixed-connection segmented prefabricated assembly type composite beam and construction method thereof
The invention discloses a bolting-welding mixed-connection segmented prefabricated assembly type composite beam and a construction method thereof. The composite beam comprises prefabricated main beamsegments, the adjacent prefabricated main beam segments are connected through longitudinal connecting segments to form main beam structures, and the adjacent main beam structures are connected throughtransverse connecting segments to form a bridge span structure; each prefabricated main beam segment comprises a steel beam, a concrete slab and a shear connector, and each steel beam comprises a topplate, a bottom plate and a web; and adjacent top plates are welded in a butt joint mode, adjacent bottom plates and webs are connected in a fastened mode through bolts after being welded in a butt joint mode, longitudinal connecting steel components are arranged on the top plates, and adjacent longitudinal connecting steel components are welded in a butt joint mode. The longitudinal connecting steel components are provided with round holes, first reinforcing steel bars penetrate into the round holes, second reinforcing steel bars extend out of the periphery of the concrete slabs, and longitudinal connecting segment wet joints are cast in situ between the first reinforcing steel bars and the second reinforcing steel bars; and transverse connecting segment wet joints are cast in place between the adjacent concrete slabs; the segmental prefabricated reinforced concrete composite beam is convenient to transport and hoist; and bolt welding mixed connection is adopted, overhead welding ofthe bottom plate is avoided, and construction is convenient.
本发明公开了一种栓焊混连的分段预制装配式组合梁及其施工方法，组合梁包括预制主梁节段，相邻的预制主梁节段通过纵向连接段连接形成主梁结构，相邻的主梁结构通过横向连接段连接形成桥跨结构；预制主梁节段包括钢梁、混凝土板及剪力连接件，钢梁包括顶板、底板及腹板；相邻顶板对接焊接，相邻底板和腹板对接后螺栓紧固连接，顶板上设有纵向连接钢构件，相邻纵向连接钢构件对接焊接。纵向连接钢构件设有圆孔，圆孔内穿入第一钢筋，混凝土板四周伸出第二钢筋，第一钢筋和第二钢筋之间现浇纵向连接段湿接缝；相邻混凝土板之间现浇横向连接段湿接缝。分段预制钢混组合梁，运输及吊装方便；采用栓焊混连避免了底板仰焊，施工方便。
