vivo全球AI研发中心钢结构施工关键技术研究
Key Technology for Steel Structure Construction of the vivo Global AI R&D Center
vivo全球AI研发中心为复杂钢框架-核心筒结构体系,建筑内含5道单截面箱形大跨度巨拱,巨拱最高39.0 m,最大跨度77.6 m。项目现场施工条件复杂,包含5层地下室,顶板层高差大、洞口多,施工最终选用了分段吊装法施工,实际工程中大型履带吊行驶至拱外侧钢栈桥,拱下方则搭设支撑系统,以自内向外的顺序进行施工。本文主要介绍了巨拱施工的方案选择思路,设计出了一种可供重型履带吊作业的钢栈桥以及以塔吊标准节为主的巨拱支撑系统,开展了巨拱全过程施工模拟分析和施工健康监测,二者进行对比后发现结果的吻合度较高;此外,本文还阐述了施工过程中工序配合等问题,对施工中异于常规超高层钢结构项目中的技术要点(如空间塔冠、临时塔吊附着等技术)进行了分析,可为后续同类超高层钢结构工程的实施提供一定的借鉴作用。
The vivo Global AI R&D Center project is an intricate building, featuring a steel frame core tube structure system comprised of five individual, box-shaped, large-span mega arches. The most prominent arch boasts a maximum span of 39 m, with a maximum width of 77.6 m. The construction is complex, including rare five-story basements with significant height variations and numerous openings. To overcome these challenges, a large crawler crane mounted steel trestle, and a support system was erected beneath the arches, facilitating sectional lifting from the interior outwards. This article mainly introduces the decision-making process behind selecting the construction scheme for the mega arch. A steel trestle suitable for heavy-duty crawler crane operations and a mega arch support system with tower crane standard sections as the main components were designed. The construction simulation analysis and construction health monitoring of the entire process of the mega arch were carried out, and good agreement was observed after comparing the two. In addition, this article discusses issues such as process coordination during construction, and analyzes the technical points that are different from conventional super high-rise steel structure projects during construction, such as spatial tower crowns and temporary tower crane attachments, which can provide a reference for the implementation of similar super high-rise steel structure in the future.
