Subway entrance and exit shelter ceiling with snow clearing function
The invention relates to a subway entrance and exit shelter ceiling with a snow clearing function. The shelter ceiling comprises a ceiling body, the ceiling body is of a hollow structure with openingsat the front side and the bottom, the ceiling body is of a double-layer structure, a gas flow cavity is formed in the space between the outer layer and the inner layer of the ceiling body, and gas flow holes communicating with the gas flow cavity are formed in the surfaces of the two sides of the outer layer of the ceiling body; and when gas flow causes pressure to the ceiling body, the gas flowcan flow into the inner side of the gas flow cavity through the gas flow hole on one side of the ceiling body and then flow out through the gas flow hole on the other side, so that the pressure of thegas on the ceiling body can be reduced. In short, according to the technical scheme, the problem that a traditional subway entrance and exit ceiling is likely to collapse and break down under pressure due to snow accumulation is solved through a coherent and compact structure, the problem that the side wall of the ceiling is damaged due to large wind is further solved, and furthermore the problemthat an included angle spider web at the inner side of the traditional subway entrance and exit ceiling is not likely to clear is solved.
本发明涉及一种具有清雪功能的地铁出入口遮挡棚，包括顶棚本体，所述顶棚本体为前侧及底部开口的中空结构，所述顶棚本体为双层结构，顶棚本体的外层和内层的间隔空隙处为气体流动空腔，所述顶棚本体外层的两侧表面开设有与气体流动空腔相连通的气流孔，当气流对顶棚本体造成压力时，气流可经由顶棚本体一侧气流孔流入至气体流动空腔内侧，再经由另一侧气流孔流出，可减少气体对顶棚本体的压力。简而言之，本申请技术方案通过连贯而又紧凑的结构解决了传统地铁口顶棚易因积雪而出现坍塌、压垮的问题、更进一步的解决顶棚侧壁可能因风大而出现损坏的问题，此外，更解决了传统地铁口顶棚内侧夹角蜘蛛网不易清理的问题。
