Construction method for prefabricated bridge steel jacket stand column
The invention relates to a construction method for a prefabricated bridge steel jacket stand column. Internal steel bars of the stand column are prefabricated after structural analysis; and a jig frame is arranged in an adjustable mode so as to be matched with binding of reinforcement frameworks of different lengths, fine construction of installation and welding of annular stirrups in a steel jacket, pouring of steel jacket stand column and turnover and transportation of a finished product is facilitated, and the problem that due to the fact that the self weight of the steel jacket stand column reinforcement framework is large and loads are not evenly distributed, and a grouting sleeve deviates in the reinforcement framework hoisting process is solved. The reinforcement framework is put into a mold, a template is installed, and the reinforcement framework reaches a construction position in a horizontal state and is overturned to be in a vertical state; and the prefabricated stand column is stored in a preset area for storage after being subjected to concrete pouring, mold removal and curing. According to the method, material waste is reduced, cost is saved, an assembly type treatment mode replaces integrated treatment, repeated use of all parts and templates is achieved, efficiency is improved, waste is reduced, operability is high, precision is high, the construction progress is fast, the utilization rate of machine tools and equipment is improved, and the method is safe, environmentally friendly and free of pollution.
本发明涉及一种预制装配式桥梁钢套立柱施工方法，结构解析后预制立柱的内部钢筋；胎架可调配置以匹配不同长度的钢筋骨架绑扎，便于钢套内环形箍筋安装及焊接、钢套立柱浇筑、成品翻转运输的精细化施工，解决钢套立柱钢筋骨架自重较大且荷载不均布所导致的钢筋骨架吊装过程中灌浆套筒偏位的问题；对钢筋骨架入模，安装模板，以水平态到达施工位，翻转为竖直态；对预制的立柱进行混凝土浇筑、拆模及养护后存放至预设区域进行存储。本发明减少材料浪费，节约成本，装配式的处理方式代替一体化处理，实现各零部件及模板的重复使用，提高效率、减少浪费，可操作性强，精度高，施工进度快，提高机具设备的使用率，安全环保，不产生污染。
