Large-span inhaul cable pull rod truss steel structure construction method
The invention discloses a large-span inhaul cable pull rod truss steel structure construction method. The large-span inhaul cable pull rod truss steel structure construction method comprises the steps that modeling analysis is correspondingly carried out on a curtain wall truss steel structure, a main body steel structure and a top main body structure; three-dimensional position correction is carried out on the curtain wall truss steel structure and the main body steel structure; and final assembly model analysis is carried out after model preprocessing, and corresponding installation is executed on site according to data obtained after independent calculation and mold closing calculation. According to the large-span inhaul cable pull rod truss steel structure construction method, structural arrangement is optimized, meanwhile, during construction simulation, after field butt joint and assembly of a truss are completed and inspection is qualified, vertical face lifting installation is carried out through two selected cranes, and the situation that in the lifting process of a single crane, irreversible deformation is generated due to the fact that a part is too long, and the structural quality is affected is avoided; and the strength and deformation of the truss in the lifting process meet the standard requirements, in addition, the stability of the large-span truss structure before forming is ensured by additionally arranging the top and bottom temporary supports, and the construction safety is ensured.
本发明公开了一种大跨度拉索拉杆桁架钢结构施工方法，该方法包括分别对幕墙桁架钢结构、主体钢结构以及顶部主体结构进行建模分析，对幕墙桁架钢结构和主体钢结构经过三维位置修正，以及模型预处理后的进行总装模型分析，根据单独计算和合模计算后的数据在现场执行相应的安装。本发明优化结构布置，同时，施工模拟时考虑桁架现场对接拼装完成并检验合格后再利用选定的两台吊车立面抬吊安装，避免采用单台吊车吊装过程中因构件过长产生不可逆变形影响结构质量，通过桁架吊装过程的模拟计算，保证了桁架在吊装过程中强度和变形满足规范要求，另外通过增设顶底临时支撑保证了大跨度桁架结构在成型前的稳定性，确保了施工的安全性。
