西藏拉萨会展中心膜结构工程
项 目 介 绍
Project introduction
该工程位于西藏自治区拉萨市东区新城内，包含大小两个展馆，建筑外形极其类似。2#会展中心屋顶标高26米，屋面采用钢骨架和膜的组合形式，其中钢骨架为纵横向交错布置的空间管桁架结构，平面弧形主桁架间距12米，上下弦分别作为上下层膜面的边界，各分为28个独立膜单元。整个屋顶膜包括上下层膜，竖向侧封膜以及翼缘悬挑膜，其中下层膜中间部分镂空。整个膜屋面轻盈飘逸，外形靓丽，层次感十足。
Lhasa Tibet Convention and Exhibition Center Membrane Structure
This project is located in the Tibet Autonomous Region, Lhasa City. The convention and exhibition center contains two similar pavilions. 2# exhibition center roof elevation is 26m, and it is composed of steel frame and roof membrane. The steel frame is staggered with space curved tube truss structure vertically and horizontally. The truss spacing is 12m, the upper and lower chord of the truss are the boundary of double layer membrane roof respectively. Each layer is divided into 28 independent membrane units. The whole membrane roof looks like a white cloud flying in the sky.
