Complex linear variable cross-section reinforced concrete tower column formwork system and construction method
The invention relates to a complex linear variable cross-section reinforced concrete tower column formwork supporting system and a construction method, and the construction method comprises the following steps: installing a variable cross-section adjustable formwork supporting system, and adjusting a movable supporting rod and a hydraulic supporting rod according to the line type of a tower column, so that a flexible formwork and a rigid formwork are attached to the outer surface of the tower column; concrete is poured and maintained, and a new tower column section is obtained; and the variable-cross-section adjustable formwork supporting system and the supporting and pulling truss are moved upwards section by section, and tower column concrete is poured till the designed elevation is reached. The supporting and pulling truss has the beneficial effects that the supporting and pulling truss is fixed to the poured and formed tower column, the supporting and pulling jack is used for supporting and pulling and fixing the tower column, deviation of the axis of the tower column in the construction process is avoided, and the linear precision of the tower column is improved; a variable cross-section adjustable formwork supporting system is adopted, the movable supporting rods and the hydraulic supporting rods are adjusted according to the line type of the tower column, the flexible formwork and the rigid formwork are attached to the outer surface of the tower column, the axis of the formwork is adjusted, and the concrete forming quality of the complex special-shaped cross-section tower column is improved.
本发明涉及一种复杂线型变截面钢筋混凝土塔柱支模体系及施工方法，包括以下步骤：安装变截面可调支模体系，根据塔柱线型，调整活动支撑杆和液压撑杆，使柔性模板和刚性模板贴合塔柱外表面；浇筑混凝土并养护，得到新的塔柱节段；逐节段向上移动变截面可调支模体系及撑拉桁架，并浇筑塔柱混凝土，直至设计标高。本发明的有益效果是：将撑拉桁架固定在已浇筑成型的塔柱上，通过撑拉千斤顶对塔柱进行撑拉固定，避免施工过程中塔柱轴线产生偏位，提高塔柱的线型精度；采用变截面可调支模体系，根据塔柱线型调整活动支撑杆和液压撑杆，使柔性模板和刚性模板贴合塔柱外表面，并调整模板的轴线，提高了复杂异型截面塔柱混凝土成型质量。
