摘要
研究目的:将站台雨棚柱设置在股道间,使整个站台通透、开敞、明亮,为旅客通行提供更大的便利。为全国铁路省会级车站无柱雨棚改造提供可以借鉴的工程范例。研究结论:采用密布的轻型实腹H型钢连续檩条及长悬臂檩条是减小结构自重及屋面厚度,减小挠度及跨中弯距,实现大跨度的有效方法;设置檩条横向支撑是保证檩条平面外稳定的有效措施。
Research purposes: The posts of station platform will be installed between tracks, which can make the platform more open and bright and provide comforts to the passengers and reference to the similar works.
Research conclusions:Adopting the H -beam light solid consecutive purlin and long cantilever purlin structure are the effective ways to lower the structure weight and roof thickness, reduce deflection and inter - bending and realize the large -span. Providing horizontal support to purlin is the effective measure for guaranteeing purlin plane stability.
