Mass concrete double-layer reinforcing steel bar support replacement installation construction method

The invention relates to and particularly discloses mass concrete double-layer reinforcing steel bar support replacement installation construction method. The method specifically comprises the following steps of binding lower-layer bars; mounting a temporary support; mounting a reinforcing steel bar bracket; binding upper-layer bars; enabling the reinforcing steel bar bracket to be positioned between the lower-layer bars and the upper-layer bars; dismantling the temporary support, and simultaneously installing a stand column support; and pouring concrete, wherein after the poured concrete supports the reinforcing steel bar bracket, the stand column support is dismantled. According to the method, the construction safety can be effectively guaranteed, and the temporary support can be taken out and reused; and the construction cost is greatly reduced. 本发明涉及，具体公开了一种大体积混凝土双层钢筋换撑安装施工方法，具体包括以下步骤：底筋绑扎；临时支撑安装；钢筋支架安装；面筋绑扎；所述钢筋支架位于底筋与面筋之间；临时支撑拆除，并同时安装立柱支撑；混凝土浇筑；其中，当浇筑的混凝土对钢筋支架进行支撑后，拆除立柱支撑。本发明能够有效的保证施工的安全性，还能够将临时支撑取出，重复使
