以温州奥体中心体育综合馆为例,介绍了一种大跨度体育馆中间区整体提升的施工方法。介绍了施工中设置的提升架的结构形式,并利用有限元分析技术对提升架典型节点进行数值分析,得出了类似节点设计的经验总结。根据合龙温差的概念,对结构应力和变形在合龙施工过程中受温度变化幅度的影响进行研究,并在此基础上给出一些关于合龙施工的建议和意见。
Taking the Wenzhou Olympic Sports Center Complex as an example, this paper introduces a kind of construction method for the overall promotion of the middle span of the large-span stadium. The structure of the lifting frame which is set up in the construction is introduced, and the numerical analysis of the typical nodes of the lifting frame is carried out by using the finite element analysis technology. The experience of similar node design is obtained. According to the concept of clogging temperature difference, the influence of structural stress and deformation in the process of clogging construction by temperature variation is studied. Based on this, some suggestions and suggestions on clogging construction are given.
