Assembly type corrugated steel web cantilever prefabricated assembled bridge structure and construction method
The invention discloses an assembly type corrugated steel web cantilever prefabricated assembly bridge structure and a construction method, and belongs to the technical field of bridge engineering construction.The assembly structure comprises corrugated I-shaped steel, a prefabricated top plate, an upper flange steel plate fixedly arranged on the top of the corrugated I-shaped steel, and a prefabricated bottom plate; the prefabricated top plate is fixedly arranged on a lower flange steel plate at the bottom of the corrugated I-shaped steel; the prefabricated bottom plate is close to the side end and is positioned and connected to the lower flange steel plate through a plurality of self-adjusting connecting pieces in the longitudinal direction, and a concrete pouring gap is formed between the side end of the prefabricated bottom plate and the corrugated I-shaped steel. In a concrete pouring gap, the corrugated I-shaped steel is fixedly provided with a plurality of outer wrapping connecting pieces provided with first through holes in the longitudinal direction, the side end of the prefabricated bottom plate is fixedly provided with a plurality of U-shaped steel bars in the longitudinal direction, and the U-shaped steel bars and the first through holes are arranged in a staggered mode in the longitudinal direction and are arranged on the same longitudinal steel bar in a penetrating and sleeving mode. According to the splicing structure, the bridge and the method, the structural integrity, the construction efficiency and the construction precision are improved.
本发明公开了一种装配式波形钢腹板悬臂预制拼装桥梁结构及施工方法，属于桥梁工程建造技术领域，拼装结构包括波纹工字钢，预制顶板，预制顶板固定设置于波纹工字钢顶部的上翼缘钢板，预制底板，预制顶板固定设置于波纹工字钢底部的下翼缘钢板；预制底板靠近侧端且沿纵向利用若自调节连接件定位连接于下翼缘钢板上，并在预制底板侧端和波纹工字钢之间设置有混凝土浇筑间隙；在混凝土浇筑间隙中，波纹工字钢沿纵向固定设置有若干开设有第一通孔的外包连接件，预制底板侧端沿纵向固定设置有若干U型钢筋，U型钢筋和第一通孔沿纵向交错设置且穿套于同一纵向钢筋上。本发明的拼装结构、桥梁及方法提高结构整体性、施工效率和施工精度。
