一、一个侧面的模板不安装框架柱的钢筋通常大而密,柱底节点处几根梁的钢筋交叉经过,或梁头的钢筋拐弯插入,致使柱内空隙很小,施工时很难将混凝土从柱顶浇灌下去当混凝土下落高度超过3m时、按钢筋混凝土拖工规范要求应使用串筒下料,但实际施工时串筒插不进,我们的经验是在支模板时,根据施工需要,选定柱子的一侧模板只安装2～3m高,其余模板暂不安装,柱模板四周的、立管、箍管、顶掌和拉管按正常加固方法安装好,施工时混凝土从没有模板的侧面通过小馏槽向柱内浇灌,边浇灌边往上封
First, a side of the template does not install the frame column reinforcement is usually large and dense, the bottom of the column at the bottom of a few beams of the steel cross, or the bar head of the steel bar inserted, resulting in small gaps in the column, the construction of the concrete is difficult Watering from the top of the column When the falling height of the concrete exceeds 3m, the string and tube blanking should be used according to the requirements of the reinforced concrete towman’s work, but the actual construction time cannot be inserted into the string. Our experience is when supporting the formwork, according to the construction requirements, The side of the selected column template is only installed 2 ~ 3m high, the remaining template temporarily installed, the column template around the riser, hoop tube, top palm and pull tube installed by the normal reinforcement method, the construction of concrete from the template is not Side through the small distillery to the column watering, while watering edge up
