Integral hoisting method for large segment of eccentric steel beam
The invention relates to the technical field of bridge construction, and discloses an eccentric steel beam large-section integral hoisting method which comprises the following steps: integrally hoisting single-section hoisting units; wherein the single inter-node hoisting unit comprises 0.5 inter-node guide beams and 0.5 inter-node steel beams. Another hoisting method comprises the following steps of: adjusting the gravity center of the single-section hoisting unit to a plane position formed by three hoisting points of the girder erection crane by the girder erection crane; a large cross beam of the girder erection crane moves in the first direction, and an oil cylinder counter-force base moves in the first direction and is fixed; configuring three lifting points of a lifting appliance of the girder erection crane; and the single-section hoisting unit is vertically hoisted. According to the technical scheme, the steel beam sections are optimized to form the single-section hoisting unit, and integral hoisting can be achieved. Furthermore, the technical problem of integral hoisting of the large segment of the eccentric steel beam is solved by adjusting an unbalanced force control means. The technical scheme is feasible, construction is simple, the hoisting weight of the steel beam is reduced, the construction risk is reduced, and the risk is controllable; and meanwhile, the construction cost is greatly saved.
本发明涉及桥梁施工技术领域，公开了一种偏心钢梁大节段整体吊装方法，整体吊装单节间吊装单元；其中，单节间吊装单元包括0.5节间导梁和0.5节间钢梁。另一种吊装方法，包括：架梁吊机调整单节间吊装单元的重心至与架梁吊机三吊点组成的平面位置内；架梁吊机的大横梁向第一方向移动，油缸反力座向第一方向移动并固定；配置架梁吊机之吊具三吊点；垂直吊起单节间吊装单元。本申请的技术方案，优化钢梁节段组成单节间吊装单元，可实现整体吊装。进一步的，通过调整不平衡力控制手段，解决了偏心钢梁大节段整体吊装的技术难题。本发明的技术方案可行，施工简单，降低了钢梁吊装重量，降低施工风险，风险可控；工期可控，同时极大节约了施工成本。
