Segmented dismantling construction method of large-span beam string structure
The invention discloses a segmental dismantling construction method for a large-span beam string structure. The segmental dismantling construction method comprises the following steps of arranging a plurality of breaking points on a beam string structure, and arranging supporting jig frames for supporting the beam string structure at the breaking points; dismantling secondary components, irrelevant to a transverse supporting frame system for keeping the beam string structure, on the beam string structure; cutting the beam string structure at the breaking points to form multiple sections of beam string units; disconnecting the beam string structure units from building vertical force bearing components, hoisting the beam string structure units to the ground and then disassembling the beam string structure units; and dismantling supporting jig frames. The segmented dismantling construction method is suitable for beam string structures of various space models, the conversion principle of astructure stress system in the dismantling process is clear, no special requirement is needed for a field site, safety is good, implementation performance is high, the influence on the surrounding environment is smaller, construction operation is easy, investment of large hoisting equipment and the number of supporting measures is reduced,, the construction cost is saved, and the construction cost is lower.
本发明公开了一种大跨度张弦梁结构的分段拆除施工方法，包括以下步骤：在张弦梁结构上设置多个分断点，并在每个分断点处设置为张弦梁结构提供支承的支承胎架；拆除张弦梁结构上与保持张弦梁结构横向支承框架体系无关的次要构件；在分断点处对张弦梁结构进行切割，形成多段张弦梁单元；断开张弦梁单元和建筑竖向承力构件之间的连接，将张弦梁单元吊装至地面后进行分拆；拆除支承胎架。这种分段拆除施工方法，适用于各种空间造型的张弦梁结构，拆除过程中结构受力体系的转化原理清晰，对现场场地无特殊要求，安全性好，实施性强，对周边环境的影响较小，施工操作简单，减少了大型吊装设备和支承措施量的投入，节约施工成本，工程造价较低。
