Construction method for assembling whole truss of large-span plane truss on ground
The invention discloses a construction method for large-span plane truss ground assembly and whole truss hoisting, which comprises the following steps: reinforcement of a truss assembly site: after the truss assembly site is selected, planning and reinforcing the site; surveying and mapping the ground projection line of the truss: surveying and setting out on the site, and determining the ground projection line of the whole truss structure; arranging a support jig frame assembled on the ground of the truss: reasonably arranging the stirrup-shaped support jig frame and then connecting and fixing the stirrup-shaped support jig frame with the ground; subsection assembling is conducted on the truss ground, specifically, block-by-block and subsection type rapid welding assembling is conducted; hoisting the truss and turning over in the air, namely turning over the large-span truss in the air after integrally hoisting the large-span truss; off-site hoisting and fixing of the truss: off-site two-point hoisting is adopted; and truss construction detection: detecting the whole truss. The large-span truss is spliced and hoisted by blocks, the splicing efficiency is improved, it is guaranteed that rollover and hoisting of the whole truss can meet the precision requirement, construction safety is guaranteed, and the purposes of saving cost, shortening the construction period and guaranteeing quality are achieved.
本发明公开了一种大跨度平面桁架地面拼装整榀吊装的施工方法，包括桁架拼装场地的加固：选取桁架拼装场地后，对场地进行规划和加固；桁架地面投影线的测绘：在场地上进行测量放线，确定出整个桁架结构的地面投影线；桁架地面拼装的支撑胎架设置：将马镫形支撑胎架合理的布置后和地面连接固定；桁架地面分段拼装：进行分块分段式快速焊接拼装；桁架起吊空中侧翻：将大跨度桁架整体吊装后在空中侧翻；桁架场外吊装固定：采用场外两点起吊；桁架施工检测：对整体桁架进行检测。本发明通过将大跨度的桁架分块拼装吊装，提高拼装效率，保证整榀桁架的侧翻和吊装能够符合精度要求，确保施工安全性，达到节约成本，缩短工期，保证质量的目标。
