斯里兰卡Sooriyawewa国际板球场主看台为弧形变截面钢管桁架,单榀桁架长度大、重量重,该工程由中国企业施工,采用中国国内整体加工给运输带来困难。施工中结合实际采用整体加工、相贯线切割后散件运输的方式运达现场,该文介绍了采用胎架法现场拼装单榀弧形变截面桁架的施工技术,对其他工程大型异型桁架散件的现场拼装施工具有一定的参考价值和借鉴作用。
The main stand of Sooriyawewa International Cricket Stadium in Sri Lanka is an arc-shaped, variable-section steel tube truss with a single truss length and heavy weight. The project is being constructed by a Chinese company and the overall domestic processing in China presents difficulties in transportation. Construction combined with the actual use of the overall processing, the intersecting line after cutting the way the pieces of transport arrived at the scene, the article introduced the use of tire frame method of assembling a single arc arch cross-section truss construction technology, other large truss shaped scattered Pieces of the site assembly construction has a certain reference value and reference.
