Construction method for detachable bracket of large cantilever bent cap
The invention relates to a construction method of a detachable bracket of a large cantilever bent cap. The construction method comprises the specific steps that bracket installation is conducted before a bent cap formwork is laid, wherein six fixed brackets are arranged in parallel to form six rows; then six jacks are prepared and arranged in two rows, the heights of the jacks are adjusted according to the elevation of the bent cap formwork, distribution beams are fixedly installed between the tops of the two corresponding jacks in different rows, and four rows of detachable movable brackets are installed at the tops of the three distribution beams; finally, the outer side fixing brackets are mounted on one sides of the two rows of fixing brackets on the outermost side; after the bracket is installed, capping beam formwork and anchor mouth construction is conducted above the bracket; and the detachable movable bracket is dismounted and prestress construction is performed. According tothe detachable movable bracket, the jack is used for supporting, after concrete pouring of the bent cap formwork is completed, the detachable movable bracket is detached by lowering the jack, enough anchor mouth prestress tensioning space is guaranteed, meanwhile, detaching is convenient, and construction is safe and reliable.
本发明是一种大挑臂盖梁可拆卸托架施工方法，具体步骤为：在盖梁模板铺设前进行托架安装：首先将六个固定托架平行设置形成六排；然后准备六个千斤顶，并将六个千斤顶分为两排设置，按照盖梁模板的标高调整千斤顶的高度，在不同排的相对应的两个千斤顶顶部之间固定安装分配梁，并在三个分配梁顶部安装四排可拆卸移动托架；最后在最外侧的两排固定托架一侧安装外侧固定托架；托架安装完成后，在托架上方进行盖梁模板、锚口施工；可拆卸移动托架拆除及预应力施工。本发明可拆卸移动托架通过千斤顶进行支撑，盖梁模板混凝土浇筑完成后，通过降低千斤顶拆除可拆卸移动托架，保证足够的锚口预应力张拉空间，同时拆卸方便，施工安全可靠。
