Low-cost concave beam string construction method
The invention relates to the technical field of beam string construction, and discloses a low-cost concave beam string construction method. The method comprises the following steps od mounting pipe trusses at two ends, performing segmented construction on upper string box girders, fixedly mounting supporting rods at the bottoms of the upper string box girders after the upper string box girders aremounted, mounting a plurality of lower string box girders after the supporting rods are mounted, the two ends of the inhaul cable are connected with the two upper chord box girders respectively, meanwhile, pull rods are installed at the two ends of the supporting rod, and the stress conditions of the inhaul cable and the two pull rods in the tensioning process are sorted through finite element analysis software. According to the low-cost concave beam string construction method, simulation and analysis can be carried out through finite element analysis software, two inhaul cables and pull rodscan be tensioned at a time, the plane stability of a beam string in the tensioning construction process is guaranteed, the structural rigidity of the beam string in the construction stage is guaranteed, construction is carried out from the two ends in all procedures, and the construction efficiency is improved. Therefore, flow construction is formed, and the overall construction period of the structure is greatly shortened.
本发明涉及张弦梁施工技术领域，且公开了一种成本低的下凹型张弦梁施工方法，包括对两端的管桁架进行安装，然后进行上弦箱梁的分段施工，在多个上弦箱梁安装完毕后，在多个上弦箱梁的底部固定安装支撑杆，支撑杆安装完成后，将拉索的两端分别与两榀上弦箱梁之间进行连接，同时在支撑杆的两端安装拉杆，并通过有限元分析软件对拉索和两个拉杆在张拉时的受力状况进行分选。该成本低的下凹型张弦梁施工方法，能够通过有限元分析软件进行模拟和分析，使两个拉索和拉杆能够进行一次拉紧，保证张弦梁张拉施工时其平面稳定性，保证了其施工阶段的结构刚度，且各个工序分别从两端进行施工，从而形成流水施工，大大缩短了结构整体施工工期。
