折线形屋架散粮平房仓吊顶通风隔热技术

The ceiling ventilation and heat insulation technology for bulk grain warehouse of segmental roof truss

钢筋混凝土折线形屋架散粮平房仓是我国粮食储备库大量使用的标准仓型。基于该仓型吊顶通风隔热现状及传热原理,对折线形屋架散粮平房仓吊顶通风隔热技术进行了总结和分析,提出了利用屋架下弦吊挂保温、气密和防水顶棚,即在檐墙和屋脊处开设防雨百叶和通风百叶窗气窗等项措施,为粮食储备库设计和建设提供参考。

The reinforced concrete bulk grain warehouse of segmental roof truss is a standard bin type used by the majority of China＇s grain reserve depots.Based on the current bin type situation of ceiling ventilation and heat insulation and the heat transfer principle,the ceiling ventilation and heat insulation technology for bulk grain warehouse of segmental roof truss was summarized and analyzed,and such measures were put forward as hanging insulation,airtight and waterproof roof on the truss,opening waterproof shutters and louver window in the eave wall and ridge and so on,which provided reference for design and construction of grain reserve depot.
