FINE QUALITY PROJECT

Steel Structural Engineering of Inner Circle and Atrium of Suzhou Central Project

Winning Time:2016-2017year

The steel structure of Suzhou Central Project is mainly composed of atrium truss structure, atrium decorative tree, skating rink roof and bird-shaped roof. The atrium truss structure is a multi-storey, large-span, primary and secondary plane truss structure with a maximum span of 53.1 meters and a maximum installation elevation of 38.5 meters. It is connected with the foundation cap through 12 groups of truss columns. The large bird-shaped roof structure is mainly composed of roof grid, tree-shaped support column, V-shaped support column and lateral horizontal support bar. The box section steel is used in the roof grid members, and the steel tube joint is used in the connection between the member and the member, and the steel tube joint is welded between the member and the member. Tree columns and V-shaped columns are all supporting structures supporting roof grids, and all of them are steel tube structures. The bottom of the column is connected with the top of the column in the concrete floor, and the column branches are connected with the grid nodes through different forms such as articulation or rigid connection. The lateral horizontal support bar mainly supports the elevation grid structure. One end is connected to the structure floor by buried parts, and the other end is connected to the grid structure.

Steel Structure Engineering of Modern Media Plaza Project

Winning Time:2015-2016year

Installation of flexible steel catenary roof with large height difference and high height in atrium of this project office building. Installation and construction of 2300t giant truss at high altitude under differential settlement conditions at both ends. The construction and installation of mega-truss connection between main and auxiliary buildings under the condition of large differential settlement and unstable settlement can solve the problems of large volume, heavy components, complex structure, overhead installation, etc. At the same time, the problem of additional stress in steel structure truss caused by uneven settlement of shelf points at both ends should also be solved. Components with large cross-section size, irregular joints, large weld volume of steel pipe (steel bar) intersecting line, high installation accuracy requirements, various and complicated forms of steel castings, application of lead rubber bearings, strict control of pre-stressed steel structure.
