一种用于空心墩封顶的拉压结合支撑体系及施工方法
本发明公开了一种用于空心墩封顶的拉压结合支撑体系,包括简支式提拉框架钢梁承载系统、拉压结合式强支撑体系、提拉模板系统、限位系统、微调系统、防裂系统和防漏浆系统,利用本发明的施工方法在进行空心墩或空心塔封顶时,可以避免人孔预留,极大减少了孔内预留的数量,主要承力构件提拉模板系统为永临结合,加大结构的安全性,减少施工接缝并在墩顶接缝处设置型钢增强连接;拉压结合式强支撑体系为辅助受力体系,减少型钢用量,避免牛腿可能对侧壁混凝土产生的拉应力,通过整体预制和吊装减少空中作业,最大程度保证施工的安全。
The invention discloses a tension and compression combined supporting system for capping a hollow pier. The system comprises a simply supported type lifting frame steel beam bearing system, a tensionand compression combined type strong supporting system, a lifting template system, a limiting system, a fine adjustment system, an anti-cracking system and an anti-slurry leakage system. When the construction method is used for capping the hollow pier or a hollow tower, manholes can be prevented from being reserved, the number of reserved manholes is greatly reduced, a main force-bearing componentlifting formwork system is combined permanently and temporarily, the structural safety is improved, construction joints are reduced, and profile steel is arranged at pier top joints to enhance connection; the tension and compression combined type strong supporting system is an auxiliary stress system, the using amount of profile steel is reduced, the tensile stress possibly generated by a bracketon side wall concrete is avoided, aerial operation is reduced through overall prefabrication and hoisting, and the construction safety is guaranteed to the maximum extent.
