深科技城一期裙房大跨度钢梁及钢桁架施工技术

CONSTRUCTION TECHNOLOGY OF LONG-SPAN STEEL BEAMS AND STEEL TRUSSES FOR THE PODIUM OF THE FIRST PHASE OF SHENZHEN SCIENCE AND TECHNOLOGY CITY

以深圳市深科技城一期A塔楼裙房大跨度钢梁及钢桁架的施工为依托,针对大跨度钢梁跨度大,重量重,钢桁架复节节点多等施工特点,简要阐述了大跨度钢梁及钢桁架的施工作业环境,并对裙房大跨度钢梁及钢桁架的采用支撑胎架法、地面拼装整体吊装法等相关施工过程进行了详细的介绍。

Based on the construction of large-span steel beams and steel trusses in the podium of Tower A of Shenzhen Science and Technology City Phase I, in view of the construction characteristics of long-span steel beams,such as large span, heavy weight, and many steel truss compound joints, a brief introduction and analysis are made.The construction operation environment of long-span steel beams and steel trusses is introduced, and the relevant construction processes such as the supporting tire frame method and the ground assembly overall hoisting method for the large-span steel beams and steel trusses of the podium are introduced in detail.
