大跨度钢结构滑移施工技术研究

Research on Sliding Construction Technology of Long-Span Steel Structure

在大跨度场馆建造过程中,钢结构工程更具代表性。某会展中心项目最大跨度58.2 m,为切实保证工程质量、快速推进施工进度,项目钢桁架采用滑移施工工艺。该滑移轨道由滑移结构、滑移支撑结构、动力系统、计算机控制系统以及滑轨等组成,项目通过框架结构安装、滑移轨道调校及桁架吊点设计等一系列研究,有效保证了桁架的施工质量及进度,为项目带来了较好的社会效益及经济效益。

In the construction process of large-span venues,steel structure engineering is more representative.The maximum span of a convention and exhibition center project is 58.2 m.In order to ensure the quality of the project and promote the construction progress quickly,the steel truss of the project adopts the sliding construction technology.The sliding track is composed of sliding structure,sliding support structure,power system,computer control system and slide rail,etc.Through a series of studies on frame structure installation,sliding track adjustment and truss lifting point design.
