Report from our correspondent (reporter Ye Xiao) at the beginning of 4, Tsinghua University Beijing Gouyi architectural design limited company architects, structural designer in a row, to our construction of Wuhan Katie building expansion project of steel structure engineering inspection, gave height the affirmation to the site installation progress, construction quality, safety measures, lifting scheme. As of the end of 4, the main structure of the project successfully completed.
Wuhan Katie expansion project, building is steel structure engineering for Beijing Gouyi Architectural Design Co., the company excellent project manager Weng Chongguang is responsible for the implementation of management and coordination. General building height of 16.592 meters, a height of 12.9 meters, the main structure is composed of 3 pieces of steel lattice columns supporting the roof system, the whole structure can be divided into three subsystems; the three root lattice column can be used as a subsystem, where the GZ2 is located in building axis 7-8 axis position; GZ1 and GZ1a are located on both sides of the axis distance from the axis, in about 10.75 meters, 2.5 meters distance of 3 axis, lattice column were 4 D400 circular steel tube as a supervisor, tube to support and abdominal rod is connected, forming section column structure for the 1500*1500 lattice.
The roof system is divided into tree bottom supporting subsystem and the house shell net rack system. Roof covering material using hollow glass and composite heat insulation plate. Roof in the surrounding drainage method.
Project Manager Weng Chongguang introduces, the technical difficulties of the project lies in the installation of roof latticed shell system, because of the design of the ellipsoid single-layer drum joints reticulated shell structure, which belongs to the typical structure of three-dimensional space, space positioning, rely on to build 3D model to guide and control component and node at the same time, the site is narrow, cannot use the large crane also, this brought influence on installation plan, schedule.
The project department and installation team to understand the design drawings, combined with the construction site, many of the construction scheme is to adjust and perfect, decided to adopt the steel headframe support, the construction scheme of high bulk, and by the owners, supervision, design approval. At present, the main project completion.
