Integral dismantling method for 0 # block bracket of continuous rigid frame bridge
The invention relates to an integral dismantling method for a 0 # block bracket of a continuous rigid frame bridge, which comprises the following steps: when the 0 # block bracket is installed, two carrying pole beams are welded at the bottom of an upper-layer bearing beam of the bracket, and welding lifting lugs are welded at two ends of each carrying pole beam; when 0 # block concrete is poured,vertical sleeves are pre-buried in the positions right opposite to the four lifting lugs of the carrying pole beam to serve as lifting rope through holes; after the 0 # block is poured, a guide wheeland a winch are installed on the top surface of the 0 # block and close to each lifting rope through hole, and a lifting rope of the winch bypasses the guide wheel and penetrates through the liftingrope through holes to be connected with a lifting lug of the carrying pole beam; when the bracket is disassembled, the upper bearing beam is lifted away from the unloading device, and then the unloading device is taken down; the upper-layer bearing beam is lowered to the lower-layer bearing beam, and the upper-layer bearing beam is temporarily welded; and the bracket is integrally lifted upwards,the corbels are dismounted, and finally the bracket integrally falls to the ground. Operation is convenient, safe and efficient, and the problems that when an existing 0 # block bracket is disassembled, efficiency is low, and safety is poor are solved.
本发明涉及一种连续刚构桥0#块托架整体拆除方法，在0#块托架安装时，在托架上层承重梁的底部焊接两根扁担梁，每根扁担梁两端焊接一吊耳；浇筑0#块混凝土时，正对扁担梁4个吊耳位置分别预埋竖向套管作为吊绳通孔；0#块浇筑完成后，在0#块顶面靠近每个吊绳通孔安装一导向轮及一卷扬机，卷扬机吊绳绕过导向轮并穿过吊绳通孔与扁担梁的吊耳连接；支架拆除时，先将支撑上层承重梁吊离卸落装置，然后取下卸落装置；将上层承重梁下放至下层承重梁上并临时焊接；将托架整体向上提升，拆除牛腿，最后将托架整体下落到地面。操作方便、安全、高效，解决了目前0#块托架拆除时效率低、安全性差的问题。
