Prefabricated concrete bridge deck continuous connecting plate structure and construction method thereof
The invention discloses a precast concrete bridge deck continuous connecting plate structure and a construction method thereof. The precast concrete bridge deck continuous connecting plate structure comprises a support system, a simply supported beam system, an ultra-high performance concrete connecting plate and a bridge deck layer system arranged on the simply supported beam system. The connecting plate is in a step shape, two rows of through holes are reserved in an anchoring area of the connecting plate, the connecting plate is connected with a simply supported beam system through embedded studs, and the connecting plate can be effectively prevented from cracking due to excellent deformability and high compressive strength of ultra-high performance concrete; and the ultra-high performance concrete connecting plate is prefabricated in a pressurizing and steam curing mode, the mechanical property advantages of an ultra-high performance concrete material can be better played, and the adverse effect caused by shrinkage is eliminated. According to the connecting plate, the excellent mechanical property of the ultra-high performance concrete is utilized, the requirement for telescopic deformation of the simply supported beam can be met, construction is convenient, the labor cost is reduced, the construction period is shortened, rapid replacement is convenient, and bridge deck continuity is better achieved.
本发明公开一种预制混凝土桥面连续连接板结构及其施工方法，包括支座系统、简支梁系统、超高性能混凝土连接板和设置在简支梁系统上的桥面层系统；的形状为阶梯形，连接板锚固区预留两排通孔，通过预埋栓钉与简支梁系统相连，超高性能混凝土优良的变形能力、较高的抗压强度能够有效避免连接板开裂，且通过加压、蒸养的方式预制超高性能混凝土连接板更能发挥超高性能混凝土材料的力学性能优势，消除收缩带来的不利影响。本发明中的连接板利用超高性能混凝土优越的力学性能，能够满足简支梁伸缩变形的需要，施工方便，降低人工成本，缩短施工周期，便于快速更换，更好实现桥面连续。
