Pile plate type bridge prefabricated pi-shaped beam and construction method
The invention relates to a pile plate type bridge prefabricated pi-shaped beam and a construction method. The construction method comprises the following steps that the pi-shaped beam is located, installed and constructed; constructing a wet joint of the pi-shaped beam; constructing a cover beam wet joint; and constructing the medial strip guardrail. The auxiliary positioning system has the beneficial effects that positioning installation construction is conducted through the prefabricated pi-shaped beam coupling section support auxiliary positioning system, the two pi-shaped feet of the pi-shaped beam are limited through the limiting devices, the installation precision and efficiency are improved, manual back-and-forth adjustment is avoided, and manpower is saved; the wet joint hanging formwork pouring system and the wet joint supporting formwork pouring system are adopted for conducting wet joint construction of the pi-shaped beam, the influence of limitation of the height of the bridge can be avoided, the construction requirement can be met by conducting ordered operation on the bridge floor, safety and reliability are achieved, and manpower and construction machinery cost can be saved.
本发明涉及一种桩板式桥梁预制π形梁及施工方法，包括以下步骤：π形梁落位安装施工；π形梁湿接缝施工；盖梁湿接缝施工；中央分隔带护栏施工。本发明的有益效果是：通过预制π形梁耦合断面支架辅助落位体系进行落位安装施工，通过限位装置对π形梁的两个π形脚进行限位，提高了安装精度和效率，避免了人工来回调节，节约人力；采用湿接缝吊模浇筑体系和湿接缝托模浇筑体系进行π形梁湿接缝施工，可不受桥梁高度限制影响，在桥面上进行有序操作即可完成其施工要求，安全可靠，而且可以节省人力和施工机械费用。
