Prefabricated assembly type bridge deck structure and construction method thereof
The invention discloses a prefabricated assembly type bridge deck structure which comprises prefabricated beam bodies and prefabricated connecting beams. The prefabricated beam bodies are arranged in parallel in the transverse direction of the bridge, and a construction gap is reserved between every two adjacent prefabricated beam bodies; the prefabricated connecting beam is erected above the construction gap between the two adjacent prefabricated beam bodies and covers the construction gap; transverse steel bars are arranged in the prefabricated connecting beams in a penetrating mode, are perpendicular to the longitudinal direction of the bridge and are distributed in parallel at intervals. Vertical steel bars are reserved on the top surface of the prefabricated beam bodies, and the vertical steel bars and the transverse steel bars are correspondingly welded or bound; and a cast-in-place concrete layer covers the prefabricated beam bodies, the prefabricated connecting beams, the vertical steel bars and the transverse steel bars. The invention further discloses a construction method of the prefabricated assembly type bridge deck structure. Wet joint setting and effective connection between prefabricated beam bodies can be completed without formwork supporting, a bridge deck structure forms a unified whole, good force transmission between the beam bodies is achieved, and the stress performance and the anti-seepage performance of the bridge are guaranteed.
本发明公布了一种预制装配式桥面结构，包括预制梁体和预制连接梁；预制梁体沿桥梁横桥向并列设置，相邻两预制梁体之间留有构造间隙；预制连接梁搭设在相邻两预制梁体之间的构造间隙上方，并覆盖构造间隙；预制连接梁内贯穿设置有横向钢筋，横向钢筋垂直于桥梁纵桥向设置，并相互平行间隔分布；预制梁体的顶面预留有竖向钢筋，竖向钢筋与横向钢筋对应焊接或绑接；于预制梁体、预制连接梁、竖向钢筋和横向钢筋的上方覆盖有现浇混凝土层。以及预制装配式桥面结构的施工方法。本发明无需进行模板支护即可完成预制梁体之间的湿接缝设置和有效连接，使桥面结构形成统一整体，实现了梁体之间良好的传力，保证了桥梁的受力性能和抗渗性能。
