Overall lowering and dismantling method for upper cross beam support of cable bent tower
The invention relates to an integral lowering and dismantling method for an upper cross beam support of a cable bent tower, which is characterized in that four winches are arranged on an upper cross beam top plate, two joists are symmetrically arranged at the bottom of a bracket bearing beam of the upper cross beam support along the bridge direction, and two ends of each joist are respectively connected with steel wire ropes of the two winches; meanwhile, two upper anchoring beams are arranged on a bottom plate of the upper cross beam and right opposite to each joist, two lower anchoring beams are arranged at the bottom of each joist and right opposite to the two upper anchoring beams, and hanging rods are arranged between the upper anchoring beams and the lower anchoring beams in a penetrating mode and anchoring nuts are installed; brackets of supporting brackets on the two tower columns are dismantled, the weight of the support is firstly borne by the suspenders, then the suspenders and anchoring nuts of the upper anchoring beams are gradually loosened, the weight of the support is transited to be borne by steel wire ropes of the winches, finally, the steel wire ropes are synchronously loosened by the four winches, and the support is integrally lowered. The method can ensure that the bracket is stable in attitude in the air after the bracket is removed, and ensures the construction safety.
本发明涉及一种索塔上横梁支架整体下放拆除方法，在上横梁顶板上设置4台卷扬机，在上横梁支架的托架承重梁底部顺桥向对称设置两根托梁，每根托梁两端分别与两台卷扬机钢丝绳连接，同时在上横梁底板上正对每根托梁分别设置两个上锚固梁，在每根托梁底部正对两上锚固梁设置两个下锚固梁，在上下锚固梁间穿设吊杆并安装锚固螺母；拆除两塔柱上支撑托架的各牛腿，支架的重量先由吊杆承担，然后逐渐放松吊杆与上锚固梁的锚固螺母，将支架重量过渡到由卷扬机钢丝绳承担，最后4台卷扬机同步放松钢丝绳，整体下放支架。本发明能保证牛腿拆除后支架在空中姿态平稳，保证施工安全。
