Construction method for large-span overhanging special-shaped component of steel structure roof
The invention discloses a construction method of a large-span overhanging special-shaped component of a steel structure roof, which comprises the following steps of: establishing a main vertical view and a plane projection drawing of a spatial special-shaped component structure model by adopting drawing software, determining a projection position line of a bent component, determining a tire membrane assembly space coordinate line, and constructing a large-span overhanging special-shaped component; three-dimensional space coordinates of each space rod piece and the overall structure are extracted according to the structure model, and a special tire membrane is formed; analyzing and determining three-dimensional space coordinates of the position, the shape and the size of the mould template and the position where the rod piece penetrates through the template, and giving a mould template blanking and rod piece assembly positioning map; the BIM technology is adopted for conducting three-dimensional laser scanning on the installation of the special-shaped component to obtain a point cloud model, the point cloud model and the BIM model are assembled, the position deviation is found out, the installation deviation of the rod piece is corrected in real time, control installation of the steel frame structure is completed, and hoisting is completed; the method is simple in process, convenient to operate, reliable in steel structure machining and mounting precision and quality, low in cost, short in overall construction period and good in using effect.
本发明公开了一种钢结构屋面大跨度悬挑异形构件的施工方法，包括：采用绘图软件建立空间异形构件结构模型的主立面图和平面投影图，确定弯曲构件投影位置线，确定胎膜组装空间坐标线，根据结构模型提取出每个空间杆件及整体结构的三维空间坐标，形成专用胎膜；分析确定胎具模板位置、形状大小以及杆件贯通模板位置的三维空间坐标，给出胎具模板下料和杆件组装定位图；采用BIM技术对异形构件安装进行三维激光扫描获得点云模型，将点云模型同BIM模型合模，找出位置偏差，实时纠正杆件的安装偏差，完成钢框架结构的控制安装，完成吊装；本发明中，工艺简单、操作方便、钢结构加工、安装精度、质量可靠，成本较低，且整体施工工期较短，使用效果好。
