Large-span welded ball net rack ground assembly integral lifting construction method
The invention discloses a large-span welded ball net rack ground assembly integral lifting construction method. The large-span welded ball net rack ground assembly integral lifting construction methodcomprises the steps that a roof system is projected to the ground to determine the space coordinates of all joints, and the position of a lifting point is determined according to the net rack structure form and the lifting load requirement; column head embedded parts are designed, and a platform measure tool is temporarily lifted; finally, a part machining detail drawing for generating a net rackand a temporary lifting platform is generated and used for guiding discharging and field construction; during construction of building a structural concrete column, a temporary lifting platform embedded part is installed on a column head, and pouring of the temporary lifting platform embedded part and column body concrete is completed together; net rack assembling, welding, measuring and detecting work is completed on the ground according to the space coordinates of the deepening design; a lifting platform and lifting equipment are installed on the structural concrete column, a hydraulic lifter serves as a lifting machine tool, and a flexible steel strand serves as a bearing rigging to achieve synchronous lifting of the roof net rack system; a lifter is locked after being lifted to the designed elevation, the rear supplementary rod pieces are assembled in the air, and finally installation of the net rack is completed; and an anti-corrosion and fireproof coating is sprayed.
本发明公开一种大跨度焊接球网架地面拼装整体提升工法，包括：将屋盖体系投射到地面确定各节点空间坐标，据网架结构形式、提升荷载要求确定提升点位置；设计柱头预埋件、临时提升平台措施工装；最后生成生成网架及临时提升平台的零部件加工详图，用于指导下料和现场施工；在建筑结构砼柱的施工时，在柱头安装临时提升平台预埋件，与柱身砼浇筑一并完成；按深化设计的空间坐标在地面完成网架拼装、焊接、测量、检测工作；在结构砼柱上安装提升平台及提升设备，以液压提升器作为提升机具，柔性钢绞线作为承重索具实现屋盖网架系统的同步提升；提升至设计标高后锁定提升器，在空中进行后补杆件的拼装，最终完成网架的安装；进行防腐、防火涂料喷涂。
