Large-span bailey beam portal unloading and dismantling construction method
The invention discloses a large-span bailey beam portal unloading and dismantling construction method which comprises the following steps that S1, a truss platform is erected on one side of a to-be-dismantled bailey beam, and the truss platform and the bailey beam are connected through I-shaped steel; s2, a winch is fixed to the upper portion of the truss platform, a universal fixed pulley is installed at the position, close to a to-be-disassembled bailey piece, of the bailey beam, one end of the universal fixed pulley is fixed to the winch through a steel wire rope, and the other end of the universal fixed pulley is fixed to the to-be-disassembled bailey piece through a steel wire rope; s3, transverse connection between pieces of the Bailey beam is removed, and Bailey constraint is relieved; s4, the disassembled beret pieces are slowly unloaded to an open space below or a transportation tool through a winch and a universal fixed pulley, and the beret pieces are manually disassembled, classified and put in storage; and S5, the universal fixed pulley is moved until the position of the next to-be-dismantled bailey piece accessory is fixed, the above method is repeated to dismantle the bailey piece, and the method is easy to dismantle, high in speed and good in safety and stability.
本发明公开一种大跨度贝雷梁门架卸落拆除施工方法，包括如下步骤：S1、在待拆除贝雷梁一侧搭设桁架平台，桁架平台与贝雷梁间之间用工字钢连接；S2、在所述桁架平台上方固定卷扬机，在贝雷梁待卸载贝雷片附近位置安装万向定滑轮，所述万向定滑轮一端用钢丝绳与所述卷扬机固定，万向定滑轮的另一端用钢丝绳与待拆卸贝雷片固定；S3、去除贝雷梁片与片之间的横向连接，解除贝雷约束；S4、通过卷扬机与万向定滑轮缓缓将拆除的贝雷片卸至下方空地或运输工具上，将贝雷片人工拆解，分类入库；S5、移动万向定滑轮至下一片待拆除贝雷片附件位置固定，重复上述方法拆除该片贝雷片，本发明拆卸简单、速度便捷、安全性稳定性良好。
