Construction method for large-span cantilever steel truss structure in limited space
The invention discloses a construction method of a large-span cantilever steel truss structure in a limited space, which comprises the following steps of: dividing the steel truss structure into an odd number of sections of assembly units in the span direction; wall attaching assemblies are arranged on structural beams and structural columns of the main body structure; temporary supporting jig frames are arranged below the steel truss structure, the temporary supporting jig frames are arranged below the sections of assembling units at intervals, the assembling units provided with the sections of the temporary supporting jig frames are constructed with the temporary supporting jig frames as supporting points, and the assembling units are fixed to structural beams or structural columns of the main body structure through wall attaching assemblies; assembling units at the sections without the temporary supporting jig frames are constructed, and the assembling units are fixed to structural beams or structural columns of the main body structure through wall attaching assemblies, so that the steel truss structure forms a whole; and dismantling the temporary supporting jig frame. The modular steel structure assembly construction scheme is adopted, the construction cost is reduced, the construction period is shortened, and the purposes of reducing cost and improving efficiency are achieved.
本发明公开了一种受限空间内大跨度悬挑钢桁架结构施工方法，包括，在跨度方向将钢桁架结构划分为奇数段拼装单元；在主体结构的结构梁及结构柱上设置附墙组件；在钢桁架结构下方设置临时支撑胎架，所述临时支撑胎架间隔设置于各段拼装单元下方，以临时支撑胎架作为支撑点，施工设有临时支撑胎架节段处的拼装单元，并将拼装单元通过附墙组件固定在主体结构的结构梁或结构柱上；施工不设临时支撑胎架节段处的拼装单元，并将拼装单元通过附墙组件固定在主体结构的结构梁或结构柱上，使钢桁架结构形成一个整体；拆除临时支撑胎架。本发明采用模块化的钢结构组装施工方案，降低了施工成本，缩短了施工周期，达到了降本增效的目的。
