Rolling formwork system for construction of uniform-section thin-wall hollow pier and construction method
The invention relates to a rolling formwork system for construction of a uniform-section thin-wall hollow pier and a construction method.The rolling formwork system is characterized in that a PVC annular conveying belt is arranged on a curled steel formwork in a sleeving mode to form a rolling module, a polytetrafluoroethylene film adheres to the surface of the curled steel formwork, and only two ends of the steel formwork are provided with end plates and bolt holes to be connected with a truss and a lifting frame; the formwork truss platform is lifted through the wedge block type jack, and the rolling modules are connected with one another to form a crawler device capable of walking along the surface of the pier column. The formwork system rolls and ascends, so that only binding steel bars and pouring concrete are left in thin-wall hollow pier column construction, and continuous operation and construction are not affected by the age of the concrete. The uniform-section thin-wall hollow pier formwork is lifted to form a rolling walking device with the concrete surface, sliding friction of the formwork to the concrete surface is avoided, and the concrete appearance can achieve the bare concrete effect. According to the technology, continuous and efficient construction of the bridge thin-wall hollow pier can be achieved.
本发明涉及一种等截面薄壁空心墩施工用滚动模板系统和施工方法，本发明将PVC环形输送带套于卷边钢模板上形成滚动模块，卷边钢模板表面粘贴聚四氟乙烯薄膜，钢模板仅在两个端头设置端板和螺栓孔与桁架和提升架连接，模板桁架平台通过锲块式千斤顶提升，滚动模块互相连接形成可沿墩柱表面行走的履带装置。模板系统滚动上升使得薄壁空心墩柱施工仅剩绑扎钢筋和浇筑混凝土，且能连续作业施工不受混凝土龄期影响。本发明实现了等截面薄壁空心墩模板提升与混凝土表面形成滚动行走装置，避免了模板对混凝土面的滑动摩擦，混凝土外观可达到清水混凝土效果。该技术可实现桥梁薄壁空心墩的连续高效施工。
