The invention relates to the technical field of bridge engineering, and particularly discloses a construction method for full-assembly type efficient installation of a prestressed bracket in bridge engineering. The method comprises the steps that firstly, brackets and bracket embedded part mounting positions are designed; secondly, bracket embedded parts are installed according to the design; thirdly, after the embedded position of the embedded part is rechecked, bracket section pier column concrete pouring is conducted; fourthly, after pouring is completed, an outer bracket is installed; fifthly, after the outer bracket is installed, prestress is applied to the upper tension joint; sixthly, a load simulation test is conducted after prestress is applied; seventhly, after the simulated load test is completed, a bracket upper pouring platform is constructed; eighthly, after construction of the upper pouring platform is completed, upper structure pouring is conducted; ninthly, the bracket is dismantled; the problems that in the prior art, in the bridge engineering pre-burying process, upper and lower joint shear box holes must be pre-buried precisely, the precision even cannot exceed 1-2 mm, and otherwise, normal installation cannot be achieved as a bracket with large rigidity are solved.
本发明涉及桥梁工程技术领域，具体公开了一种桥梁工程全装配式高效安装预应力托架施工方法；步骤一、托架设计和托架预埋件安装位置设计；步骤二、根据设计安装托架预埋件；步骤三，复核预埋件预埋位置后进行托架段墩柱混凝土浇筑；步骤四，浇筑完成后进行外托架安装；步骤五，外托架安装完成后进行上受拉节点预应力施加；步骤六，施加预应力后进行模拟荷载试验；步骤七，模拟荷载试验完成后进行托架上部浇筑平台施工；步骤八，上部浇筑平台施工完成后进行上部结构浇筑；步骤九，托架拆除；本发明解决了现有技术中桥梁工程预埋过程中上下节点剪力盒孔洞必须精确预埋，精度甚至不能超过1‑2mm，否则作为刚性较大的托架，无法实现正常安装的问题。
