Multi-layer variable-height space structure lifting point conversion lifting system and construction method
The invention relates to the field of building construction, in particular to a multi-layer variable-height space structure lifting point conversion lifting system and a construction method. The multi-layer variable-height space structure lifting point conversion lifting system comprises a supporting stand column, a lifting device, an assembling jig frame, a roof net rack and a gate truss; the gate truss is provided with an upper chord, a middle chord and a lower chord, the truss upper lifting point is arranged on the middle chord, the truss lower lifting point is arranged on the lower chord, the steel strand is connected with the roof lifting point and the truss upper lifting point for stage lifting and then is turned to the truss lower lifting point for overall lifting, the roof net rack and the gate truss are lifted to the supporting stand columns, and the lifting point conversion improves the construction efficiency. The construction difficulty of a multi-layer height-variable structure is well solved, main steel components are assembled on a ground jig frame, and mechanical operation is facilitated; the splicing precision and the welding quality are effectively guaranteed; the jig frame can be repeatedly used, so that the construction cost is greatly saved; a traditional scaffold and a large-tonnage crane are avoided, the aloft work amount is reduced to the minimum, the field measure cost is remarkably reduced, and the construction period is shortened.
本发明涉及建筑施工领域，尤其涉及一种多层变高空间结构吊点转换提升系统及施工方法，包括支撑立柱、提升装置、拼装胎架、屋盖网架、大门桁架；大门桁架设置上弦杆、中弦杆、下弦杆，桁架上吊点设于中弦杆，桁架下吊点设于下弦杆，钢绞线连接屋盖吊点、桁架上吊点进行阶段提升，再调转到桁架下吊点进行整体提升，将屋盖网架和大门桁架吊装到支撑立柱上，吊点转换提高施工效率，很好的解决了多层变高结构的施工难点，主要钢构件均在地面胎架拼装，便于机械化作业；无论拼装精度，还是焊接质量得到有效保障；胎架可周转重复使用，大大节约施工成本；避免传统的脚手架和大吨位吊机，高空作业量降至最少，现场措施费显著降低，节约工期。
