Construction method of laminated large-span grid structure
The invention relates to a construction method of a laminated large-span grid structure, which belongs to the technical field of steel structures, and comprises the following operation steps of: 1, carrying out partitioning and blocking treatment on roof construction; and secondly, the S1 area and the S3 area in the upper-layer roof lifting subarea are spliced in a segmented mode. And 3, integrally lifting the S1 region and the S3 region. And fourthly, a hydraulic lifting system and temporary measures are dismantled, and a post-installation rod piece is installed. And fifthly, the area S2 is spliced into a whole, and edge sealing rod pieces and post-installation rod pieces are lifted and installed. And sixthly, the Z2 area and the Z1 area are assembled into a whole, and edge sealing rod pieces and post-installation rod pieces are lifted and installed. And 7, the X3B area and the X4B area are spliced into a whole, and edge sealing rod pieces and post-installation rod pieces are lifted and installed. And 8, the lifting process is adopted in the lower layer roof lifting subareas except the X3B area and the X4B area, the hoisting process is adopted in the other subareas, and installation of the whole laminated large-span grid structure is completed. The device is compact in structure, high in efficiency, low in cost and good in operation stability.
本发明涉及一种叠层大跨度网格结构的施工方法，所属钢结构技术领域，包括如下操作步骤：第一步：屋盖施工进行分区分块处理。第二步：上层屋盖提升分区中的S1区和S3区，采用分段拼装。第三步：将S1区和S3区整体提升。第四步：拆除液压提升系统及临时措施，安装后装杆件。第五步：将S2区进行拼装成整体并提升及安装封边杆件及后装杆件。第六步：Z2区和Z1区拼装成整体并提升及安装封边杆件及后装杆件。第七步：X3B区、X4B区拼装成整体并提升及安装封边杆件及后装杆件。第八步：下层屋盖提升分区除X3B区、X4B区采用提升工艺外，其余区块均采用吊装工艺，完成整个叠层大跨度网格结构的安装。具有结构紧凑、效率高、成本低和运行稳定性好。
