钢桁架施工技术研究与分析

Research and Analysis of Steel Truss Construction Technology

随着国民经济的快速发展,各种大跨度钢桁架结构的安装已经成为建筑领域重要的组成部分。钢桁架吊装安装构件数量比较多,施工技术要求高、高处作业量较多,这就要求对钢桁架吊装和安装在施工技术和工艺上要严格控制。该文主要结合G344朱沥沟大桥的施工,对跨越河流钢桁架施工技术展开研究,阐述了G344朱沥沟大桥钢桁架的施工工艺和拼装过程。G344朱沥沟大桥钢桁架的施工技术和工艺,为今后其他桥梁钢桁架施工提供了科学指导。

With the rapid development of national economy,the installation of various long-span steel truss structures has become an important part in the construction field.The number of steel truss hoisting and installation components is relatively large,the construction technology requirements are high,and there are many high-altitude operations,which have strict control requirement on the construction technology and process of steel truss hoisting and installation.Combined with the construction of G344 Zhuligou Bridge,this paper studies the construction technology of river crossing steel truss,and expounds the construction technology and assembly process of G344 Zhuligou Bridge steel truss.The construction technology and process of steel truss of G344 Zhuligou Bridge have provided scientific guidance for the construction of steel truss of other bridges in the future.
