Method for assembling steel guide beam for pushing wide open type steel box beam
The invention discloses a method for assembling a steel guide beam for pushing a wide open type steel box beam, which comprises the following steps of: pushing from the low end of a longitudinal slope to the high end of the longitudinal slope, erecting a steel beam splicing platform between proper pier positions, selecting a cuplock type all-round scaffold, enabling the center of the cuplock type all-round scaffold to be consistent with the center line of a bridge, and adjusting the elevation of the cuplock type all-round scaffold after a bracket is erected. The gradient is ensured to be consistent with the gradient of the bridge floor, and wood plates are used for laying to serve as a test platform. The fabricated steel guide beam adopts the standard sections, structural load is fully considered, the fabricated steel guide beam can be reused, the length of the sections of the fabricated steel guide beam is reasonable, complex road condition characteristics of a mountainous area can be effectively met, transportation and installation are facilitated, the steel guide beam is convenient to assemble and easy to operate, and compared with field manufacturing of a traditional steel guide beam, the fabricated steel guide beam has the advantages that the construction cost is low, and the construction efficiency is high. The cost performance is high, and the economic benefit is remarkable.
本发明公开了宽幅开口式钢箱梁顶推用钢导梁装配方法，包括：从纵坡低端向高端方向进行顶推，在适当的墩位间进行钢梁拼装平台的搭设，选择碗扣式满堂脚手架，使其中心与桥中心线保持一致，支架搭设完成后，需要对其高程进行调整，确保坡度与桥面坡度保持一致性，并利用木板进行铺设，用做试平台。本发明装配式钢导梁采用标准化节段，充分考虑了结构负荷，可重复利用，且装配式钢导梁的节段设置长度合理，能有效满足山区较复杂的路况特征，有利于运输及安装，而钢导梁拼装方便、操作简单，相对于传统钢导梁的现场制作，性价比较高、经济效益显著。
