Beam falling system for urban railway box girder Bailey beam support dismounting, and construction method
The invention provides a beam falling system for urban railway box girder Bailey beam support dismounting and a construction method. The beam falling system for urban railway box girder Bailey beam support dismounting comprises a plurality of beam falling units, wherein each beam falling unit comprises a counter-force frame, and each counter-force frame comprises an n-shaped frame; a suspension frame which comprises a plurality of suspension rods, the suspension rods are vertically arranged, a movable beam is arranged on the inner side of the n-shaped frame, and gaskets and nuts are arranged on the suspension rods; a jack; and a bottom joist. According to the invention, a Bailey beam support adopts an in-situ falling dismounting mode, so that the site adaptability is strong, and the wholeprocess of falling, dismounting and transferring can be realized only through a single-side shortcut; the occupied area is small, and adverse effects on surrounding buildings and the environment are small; the Bailey beam support is dismounted through a counter-force frame, the mechanical construction degree of a bridge and the matched construction technology of the bridge are improved, the numberof operators is reduced, and the construction safety risk is effectively reduced. The construction efficiency is remarkably improved, rapid falling and dismounting can be achieved, the aerial work time is shortened, and potential safety hazards of equipment and personnel construction are reduced.
本发明提供一种市域铁路箱梁贝雷梁支架拆除用落梁系统及施工方法，包括多个落梁单元，落梁单元包括：反力架，反力架包括门字架；悬吊架，悬吊架包括多根吊杆，吊杆竖直设置，门字架内侧设有活动梁，吊杆上设有垫片和螺母；千斤顶；底部托梁。本发明中，贝雷梁支架采用原位下落的拆除方式，场地适应性强，仅需单侧便道即可实现下落、拆除、转运全过程；占用场地较小，对周边建筑物及环境的不利影响较小；利用反力架拆除贝雷梁支架提高了桥梁的机械化施工程度及其配套施工技术，减少了作业人员数量，有效降低了施工安全风险；施工效率显著提高，能实现快速的下落和拆除，缩短了高空作业时间，降低设备及人员施工的安全隐患。
