Narrow-space long-span multi-surface special-shaped combined steel truss installation construction method
The invention relates to the technical field of combined steel truss installation construction, in particular to a narrow-space long-span multi-surface special-shaped combined steel truss installationconstruction method. The method is characterized in that a BIM technology is utilized to optimize arcs and establish a high-level control network, and field data is finely adjusted in combination with a computer; during field construction, steel truss segments are spliced, full hall scaffold operation platforms and supporting frames are erected at building structure ends and steel truss connection parts synchronously, and a main truss is formed through assembling and welding; and then sliding units are formed through connection of secondary trusses among main trusses, and existing concrete linking beams are utilized to arrange sliding tracks, and in-place sliding is performed according to a structure accumulating sliding mode. Through the method, the quantity of scaffolds in use can be greatly reduced, the method is safe and reliable, most overhead work is reduced, construction is convenient, a machine used for lifting is relatively small, and mechanical cost is low. The method is mainly applied to the technical field of combined steel truss installation construction.
本发明涉及组合钢桁架安装施工技术领域，更具体而言，涉及一种狭小空间大跨度多曲面异型组合钢桁架安装施工方法。其特征在于：利用BIM技术，优化弧线，建立高等级控制网，结合计算机对现场数据进行微调，现场施工时将钢桁架分段拼装并且同步在建筑结构端部和钢桁架连接部位搭设满堂脚手架操作平台及支撑架，组装焊接成一榀主桁架，然后通过主桁架之间的次桁架连接形成滑移单元，利用已有混凝土连系梁设置滑移轨道按照结构累积滑移方式进行滑移就位，本方法可大大减少脚手架使用量且，安全可靠，减少大部分高空工作量，施工便捷、吊装使用机械相对较小、机械费用低，本发明主要用于组合钢桁架安装施工技术领域。
