超高层建筑自由曲面单层网壳屋顶安装施工

Installation Construction of Free-Form Surface Single-Layer Reticulated Shell Roof for Super Tall Building

苏州现代传媒广场采用曲面单层网壳屋面结构安装中存在空间定位难度大、高空拼装焊接体量大、安装偏差控制难、累积变形合拢难等问题。为了解决上述问题,采用了桁架分段高空拼装方法,确保了工程的安装精度。

There are many difficulties in installation of free-form surface and single-layer reticulated shell roof structure for Suzhou Modern Media Square, such as： space positioning, high-altitude assembling and welding, installation deviation control and accumulative deformation closure. In order to solve the above-mentioned problems, the high-altitude segment assembling of truss was adopted to ensure installation precision of the project.
