摘要:
天长全民健身中心体育场钢屋盖造型呈钻石状,主结构由径向片桁架、外环环向立体桁架和折线形平面桁架组成,弦杆交错布置,具有传力途径复杂、安装难度大的特点.将钢屋盖施工区域按建筑平面逆时针分为1～8区,从1区和8区分别按顺时针和逆时针逐步安装,施工顺序为:1区8区→2区7区→3区6区→4区5区.利用3D3S软件对管桁架拼装胎架、管桁架吊装单元、管桁架临时支撑方案、管桁架合拢、管桁架卸载方案等关键施工要点进行了施工分析.分析结果表明:管桁架吊装吊点布置、临时支撑的位置与数量设置、支撑卸载的先后顺序对钢结构屋盖的受力具有较大影响,本项目所选的施工技术,施工过程中结构挠度较小,构件应力比处于低应力状态,施工方法安全可靠.
Abstract:
The steel structure roof of Tianchang National Fitness center Stadium is diamond-shaped. The main structure is composed of the radial plate truss, the outer annular three-dimensional truss and the folded plane truss. The chords are staggered, which has the characteristics of complex force transmission and difficult installation. The construction area of steel roof is divided into 1～8 zones counterclockwise according to the construction plane, and the installation is done clockwise and counterclockwise respectively from Area 1 and 8. The construction sequence is as follows: Zone 1, Zone 8 → Zone 2, Zone 7 → Zone 3, Zone 6 → Zone 4, zone 5. 3D3S software is used to analyze the key construction points such as tube truss assembling frame, tube truss hoisting unit, tube truss temporary support scheme, tube truss closing and tube truss unloading scheme. The analysis results show that the hoisting point arrangement of pipe truss hoisting, the location and quantity setting of temporary supports, and the sequence of supporting and unloading have great influence on the stress of steel structure roof. All the construction technologies selected in this project are safe and reliable because the structural deflection is small and the component stress ratio is in a state of low stress during construction.
