Jig frame for integrally prefabricating and hoisting large pier body reinforcing steel bars and pier body reinforcing steel bar construction method
The invention discloses a jig frame for integrally prefabricating and hoisting large pier body reinforcing steel bars, and the jig frame comprises a main frame composed of square steel, wherein the front side face, the rear side face, the left side face and the right side face of the main frame are provided with transverse rods and a plurality of reinforcing rods respectively, and the transverse rods are arranged in the middles of the front side face, the rear side face, the left side face and the right side face of the main frame; the reinforcing rods are arranged between the main frame and the transverse rods and define a rhombus; a plurality of steel clamping pieces are arranged at the top and the bottom of the main frame respectively, and a plurality of clamping grooves used for clamping reinforcing steel bars are evenly formed in each steel clamping piece at intervals. Standardization and prefabrication of large pier body steel bar construction are achieved, the turnover speed ofthe pier body platform support and the formwork is increased, the investment cost is reduced, the construction difficulty is reduced, the steel bar installation precision is guaranteed, and the jig frame is simple in structure, easy to manufacture and high in repeated utilization rate.
本发明公开一种大型墩身钢筋整体预制吊装的胎架，包括由方钢组成的主框架，所述主框架的前、后侧面和左、右侧面上分别设有横杆和若干加强杆，所述横杆设置于所述主框架的前、后侧面和左、右侧面的中部，所述加强杆设置于所述主框架和所述横杆之间，并且围成菱形；所述主框架的顶部和底部分别设有若干钢夹片，每一所述钢夹片上均匀间隔布置有若干用于夹住钢筋的卡槽，本发明还公开相关的墩身钢筋施工方法。本发明实现了大型墩身钢筋施工标准化、预制化，加快了墩身平台支架和模板的周转速度，减少投入成本，降低了施工难度，并保障了钢筋安装精度，而且胎架结构简单，易于制作，重复利用率高。
