Construction method for mounting 7-shaped cantilever pipe truss
The invention discloses a construction method for mounting a 7-shaped cantilever pipe truss, which comprises the following steps of: S1, carrying out integral modeling on a truss structure, and carrying out reverse deformation to control integral deformation; s2, an operation platform is erected before the truss is installed, and a finished product support and a centering structure are installed; s3, assembling and welding a truss on the bottom surface, and mounting a truss hoisting auxiliary device and a crawling ladder on the truss; s4, the truss is hoisted, and the hoisting state of the truss is adjusted to the installation state; s5, the truss is transferred to the mounting node, and welding of the truss and the finished support is completed; s6, the hoisting equipment is unhooked, and redundant hoisting auxiliary devices on the truss are removed; according to the construction method for installing the 7-shaped cantilever pipe truss, rapid alignment and one-time installation in place can be achieved, the high-altitude operation time is shortened, the construction period is shortened, and the safety risk is reduced; high-altitude segmented welding is avoided through overall assembly, and the quality risk is reduced; and pre-stress analysis is adopted, and a pre-deformation measure is adopted, so that support-free installation is realized, and the measure cost investment is reduced.
本发明公开了一种用于7字型悬臂管桁架安装的施工方法，包括以下步骤S1.对桁架结构进行整体建模，并做反向变形量以控制整体变形；S2.在桁架安装前搭设操作平台、安装成品支座和对中结构；S3.在底面组装焊接桁架，并在桁架上安装桁架吊装辅助装置以及爬梯；S4.吊起桁架并调整桁架吊装状态至安装状态；S5.转运桁架至安装节点处并完成桁架与成品支座的焊接；S6.起重设备脱钩并桁架上拆掉多余的吊装辅助装置；本发明提供的用于7字型悬臂管桁架安装的施工方法，可快速对正，一次安装就位，减少高空作业时间，节省工期，降低安全风险；整体拼装避免高空分段焊接，减少质量风险；采用预先受力分析，采取预变形措施，实现无支撑安装，降低措施费用投入。
