摘要
某单层大跨厂房,钢屋盖由10榀桁架组成,安装高度97m,桁架跨度30m,主要截面形式为H型钢。该钢结构屋盖施工高度高、构件长度长、质量大、施工作业面小。根据结构特点,采取在桥架大梁安装临时支撑架的措施辅助桁架安装。详细介绍了屋盖钢桁架拼装的测量控制。
The steel roofs of some single-layer large-span factory consist of ten-story trusses with 97m installation height and 30m span.The trusses are H-shaped steel mainly.It had high construction height,long components,large weight,small working area,so temporary supports were applied for truss installation.Furthermore,the measurement control for steel truss assembly were introduced in detail.
