Large-span corrugated steel web continuous beam structure suitable for segment assembly and construction method
The invention discloses a large-span corrugated steel web continuous beam structure suitable for segment assembly and a construction method, the large-span corrugated steel web continuous beam structure comprises a middle cross beam and a main beam segment, and the middle cross beam comprises a middle cross beam top plate, a middle cross beam bottom plate and a steel box; each main beam section comprises a main beam top plate, a main beam bottom plate and a plurality of corrugated steel webs; the middle cross beam top plate and the middle cross beam bottom plate are concrete plates; a plurality of shear nails are uniformly distributed on the outer surfaces of a steel box top plate and a steel box bottom plate of the steel box, and a plurality of longitudinal horizontal stiffening ribs are arranged on the outer surfaces of flat steel webs connected with the main beam sections in the height direction; horizontal stiffening ribs corresponding to the longitudinal horizontal stiffening ribs are arranged on the inner side surface of the flat steel web; and each longitudinal horizontal stiffening rib extends to be connected with all the corrugated steel webs on the corresponding side. During construction, the middle cross beam top plate and the middle cross beam bottom plate are poured twice, and a pouring hole and an air outlet hole are additionally formed in the steel box bottom plate. The corrugated steel web continuous beam is simpler in structure, more convenient to construct, lighter in section and better in durability.
本发明公开了适合节段装配的大跨径波形钢腹板连续梁构造及施工方法，包括中横梁和主梁节段，中横梁包括中横梁顶板、中横梁底板和钢箱；主梁节段均包括主梁顶板、主梁底板和若干波形钢腹板；中横梁顶板和中横梁底板均为混凝土板；钢箱的钢箱顶板和钢箱底板的外表面均布设若干剪力钉，与主梁节段相接的平钢腹板的外表面均沿高度方向设有若干纵向水平加劲肋；平钢腹板的内侧面对应每一纵向水平加劲肋均设有水平加劲肋；每一纵向水平加劲肋均延至与相应一侧所有波形钢腹板连接。施工时，分两次浇筑中横梁顶板和中横梁底板，并在钢箱底板增设浇筑孔及出气孔。本发明使波形钢腹板连续梁的构造更简单，施工更便捷，节段更轻，耐久性更好。
