Variable cross-section pier column top formwork construction method
The invention discloses a variable cross-section pier column top formwork construction method, and relates to the technical field of building construction. Comprising the steps that firstly, a pier body is poured, and after a first pier body section and a second pier body section are poured, a wall-attached support is installed; after three sections of the pier body are poured, a jacking system is installed and comprises a C-shaped frame, a hydraulic oil cylinder, an upper reversing box and a lower reversing box, the C-shaped frame is fixedly connected with the wall-attached support, and pawls are arranged on the upper reversing box and the lower reversing box; after four sections of the pier body are poured, a rail is installed, a ladder baffle steel plate is welded to a web of the rail, the rail is arranged on the C-shaped frame in a penetrating mode, a pawl is movably connected with the ladder baffle steel plate, and a triangular supporting bracket is arranged at the top end of the rail; after the five sections of the tower body are poured, the lengthened columns, the bailey beams and the sliding beams are sequentially installed, the lengthened columns are installed on the tops of the triangular supporting brackets, and the hanging frame system and the formwork system are installed at the lower ends of the sliding beams. According to the construction method, jacking of the frame body is simple, construction quality is guaranteed, construction progress is fast, and operation is easy, convenient and safe.
本发明公开了一种变截面墩柱顶模施工方法，涉及建筑施工技术领域。包括：首先浇筑墩身，墩身第一节段和墩身第二节段浇筑完，安装附墙支座；墩身三节段浇筑完，安装顶升系统，顶升系统包括C型框架、液压油缸、上换向盒和下换向盒，C型框架与附墙支座固定连接，上换向盒和下换向盒上均设置棘爪；墩身四节段浇筑完，安装轨道，在轨道的腹板处焊接梯挡钢板，轨道穿设在C型框架上，棘爪与梯挡钢板活动连接，在轨道的顶端设置三角支撑牛腿；塔身五节段浇筑完，依次安装加长柱、贝雷梁和滑移梁，加长柱安装在三角支撑牛腿的顶部，在滑移梁下端安装挂架系统和模板系统。本施工方法架体顶升简单，施工质量有保障，施工进度快，操作简便安全。
