摘要
六安市体育中心体育馆形似十大著名茶品之一“六安瓜片”,采用89.7 m跨度的空间异形曲面钢桁架结构。通过对三种施工方案的技术先进性、施工安全性和经济合理性的综合对比,确定了馆内设提升架的多点不对称整体提升同步控制方案。研发了空间异形曲面钢桁架结构多点不对称整体提升同步控制技术,重点研究了提升设备与系统的不对称提升同步控制原理,提升点方案优化和提升架设计等;运用MIDAS进行了同步提升和不同步提升全过程的仿真模拟,为整体提升方案提供了参考。开发了针对体育馆钢结构的云平台海量数据处理和实时传输监测系统,并将实测结果与仿真模拟进行了对比。结果表明:多点不对称整体提升同步控制技术适用于六安体育中心体育馆大跨度钢结构屋盖结构的施工;采用的云监测技术和数值仿真技术可确保施工的安全性和可靠性。
The shape of the gymnasium of Luan Sports Center is similar to the famous top ten tea products“Luan Guapian”,the structure of the gymnasium adopts a space specially-shaped curved steel truss structure with a span of 89.7 m.This paper first proposed three construction plans.Multi-point asymmetrical overall lifting synchronous control scheme with lifting frames in the gymnasium was determined,by comparing the technological advancement,construction safety and economic rationality.Multi-point asymmetric overall lifting synchronous control technique was developed for a space specially-shaped curved steel truss structure.The paper focused on the principle of asymmetric lifting synchronous control of lifting equipment and systems,optimize the lifting point scheme and designed the lifting frame,etc.Using MIDAS,the entire simulation of synchronous lifting and asynchronous lifting was carried out,which provided countermeasures for the overall lifting scheme.Real-time monitoring system based on mass data processing and real-time transmission of cloud platform for stadium steel structures was developed,and the actual measurement results were compared with simulations.The results showed that the multi-point asymmetric overall lifting synchronous control technique was suitable for the construction of the roof structure of the gymnasium of Luan Sports Center.The cloud platform real-time monitoring technology and numerical simulation technology could ensure the safety and reliability of the construction.
