大跨度门式钢框架工业厂房吊装施工综合技术

Comprehensive Technology of Hoisting and Construction of Large-span Portal Steel Frame Industrial Workshop

工业厂房一般均采用大跨度门式结构形式,厂房的特点决定了项目工期紧、质量要求高。施工中重难点为吊装作业的机械设备的选型和施工现场的布局、顺序和施工工艺流程的控制。本文结合工程实践,总结了大跨度门式钢框架工业厂房的总体顺序及布局、施工工艺流程及质量控制要点,对其他厂房类施工具有一定参考意义。

Industrial workshops generally adopt a large-span portal structure.The characteristics of the workshop determine the tight construction period and high quality requirements of the project.The most important and difficult points in construction are the selection of mechanical equipment for hoisting operations and the control of the layout,sequence and construction process of the construction site.Based on engineering practice,this paper summarizes the overall sequence and layout,construction process and quality control points of large-span portal steel frame industrial plants,which has certain reference significance for other plant constructions.
