Dismantling method for beam heavy bailey bracket
The invention relates to the technical field of Bailey support dismantling construction methods, and provides a method for dismantling a beam heavy Bailey support. According to the technological method, during cable bent tower beam construction, the left side and the right side of a cable bent tower beam in the transverse bridge direction are each provided with a set of embedded parts, and anchoring parts are matched with the two sets of embedded parts to fix a transverse moving hanging beam; and an electric transverse moving pulley with a steel wire rope is hung on the transverse moving hanging beam, connection between the bailey supports and connection between the bailey supports and other structures are removed, and the removal sequence is that the bailey supports are symmetrically removed from outside to inside one by one, the transverse moving pulley system moves out of the bailey supports one by one, and the moved-out bailey supports are synchronously lowered. The transverse moving system has the advantages of being convenient to operate, high in dismantling efficiency, high in safety and the like, the key point of the transverse moving system is to solve the problem that the bailey truss girder is convenient to hoist and dismantle when transversely moving out of the bottom of the cross beam in the air, the application effect is good, and wide popularization prospects are achieved.
本发明涉及贝雷支架拆除工法技术领域，提供了一种横梁重型贝雷支架的拆除方法，本工艺方法在索塔横梁施工时，在索塔横梁横桥向的左右两侧各安装一组预埋件，利用锚固件配合两组预埋件分别固定一根横移吊梁，在横移吊梁上悬挂带有钢丝绳的电动横移滑车，拆除贝雷支架间及贝雷支架与其余结构间的连接，拆除顺序为由外向内逐榀对称拆除，横移滑车系统逐榀移出贝雷支架，移出的贝雷支架同步下放。本发明具有操作方便，拆除效率及安全性高等优点，该横移系统关键在于解决了贝雷桁架梁在高空横移出横梁底部便于吊装拆出的难题，应用效果较好，具有广阔的推广前景。
