Construction method and construction structure of symmetrical cantilever steel truss of high-rise building
The invention discloses a construction method and a construction structure of a symmetrical cantilever steel truss of a high-rise building, and belongs to the technical field of high-rise building construction. The method is used for carrying out ground assembly, overall lifting and high-altitude separation on the symmetrical cantilever steel truss. The method comprises the following steps of: 1) establishing a BIM model of the symmetrical cantilever steel truss; 2) carrying out stress checking calculation on the construction process; 3) manufacturing a ground assembly jig frame; 4) carrying out ground assembly; 5) carrying out overall lifting; and 6) carrying out high-altitude separation after lifting is in place, wherein a fitting point wedge-shaped graph is established by utilizing three-dimensional coordinate data of each rod piece control point during overall lifting, fitting is carried out with an original BIM model, deviation data of each rod piece control point is obtained, and adjustment and connection are carried out according to the deviation data. According to the method, the construction quality can be improved, the productivity is high, the construction progress is fast, the construction period can be shortened, the construction cost can be saved, and the economic and social benefits are high.
本发明公开了一种高层建筑的对称悬挑钢桁架施工方法及施工结构，属于高层建筑施工技术领域，该方法对对称悬挑钢桁架进行地面拼装，整体提升、高工分离；包括以下步骤：1)、建立对称悬挑钢桁架的BIM模型；2)、对施工过程进行受力验算；3)、制作地面拼装拼装胎架；4)、地面拼装；5)、整体提升；6)、提升到位后高空分离；整体提升时利用各杆件控点的三维坐标数据建立拟合点楔形图，并与原BIM模型进行拟合，获取各杆件控制点的偏差数据，并根据所述偏差数据进行调整连接。本发明能够提高施工质量，生产率高、施工进度快，可以节约工期、节省施工费用，经济与社会效益高。
