铁路桥式车站轻型站台雨棚设计要点分析

简述我国铁路站房站台雨棚的发展历程。随着西部铁路的快速发展,出现了越来越多的高架站站房,桥式车站轻型站台雨棚便应运而生。针对桥式车站轻型站台雨棚特殊的边界条件,讨论雨棚风荷载、列车风及地震作用的合理计算方式,并给出合理取值建议;作为桥上结构,提出整体式雨棚柱柱脚构造,既方便雨棚柱后期的安装,又保证雨棚柱柱脚的嵌固刚度;通过优化屋面檩条体系、细化单层压型钢板屋面构造及大样,有效地提升了桥式车站轻型站台雨棚的美观和安全性,对推动铁路站台有柱雨棚标准化建设具有积极的意义。

Analysis on the Design Essentials of the Canopy of Light Platform in Railway Bridge Station

The development history of the platform canopy of railway station in China is briefly described. With the rapid development of Western railways, more and more elevated station buildings have been built, and the light platform canopy of bridge station has emerged ever since. In view of the special boundary conditions of the light platform canopy of bridge station, reasonable calculation methods of wind load, train wind and earthquake actions on the canopy are discussed, and reasonable value suggestions are given. As a bridge structure, the integral canopy column foot structure is proposed, which not only facilitates the later installation of canopy, but also ensures the rigidity of the canopy column foot by optimization. The aesthetics and safety of the light platform canopy is effectively improved by optimizing the roofing system and refining the single-layer steel roof structure and details, and standardized construction of the column canopy of railway platform is promoted.
