摘要
以太原国电为例,重点阐述了大截面大跨度高空钢桁架在现场塔吊无法实施的情况下,采用卷扬机整体起吊抬升的技术,通过桁架主梁现场拼装,分件起吊,空中组装、焊接的安装方法,达到了钢桁架空中整体安装到位,安全可靠,质量良好的效果。
In the case of Taiyuan State grid corporation,expounds the big cross section of long span steel truss high under the condition of tower crane can not be implemented at the scene,the whole lifting hoist lifting,through at the scene of the truss girder assembled,a lifting,the installation of air assembly,welding method,to air the whole steel truss installed,safe and reliable,and the effect of quality assurance.
