拱板平房仓方案对比分析

Comparison and Analysis of Arch Slab Grain Storehouse

拱板是一种板架合一的屋盖结构,具有自重较轻、空间刚度大、整体性能好、仓内顶棚美观且容易清扫等优点。拱板施工工艺有地面预制吊装、空中预制滑移和满堂模板支撑原位整体现浇3种方式。拱板结构有预应力和非预应力两种形式。本文针对拱板平房仓预应力和非预应力两种结构形式,对比分析两种方案,设计时可根据具体使用要求确定。

The arch slab is a roof structure of slab and frame,which has the advantages of light weight,large space stiffness,good overall performance,beautiful ceiling in the warehouse and easy to clean.There are three ways of arch slab construction technology:ground prefabrication and lifting,aerial prefabrication and slip,and cast-in-situ by full house formwork support.There are two forms of arch slab structure:prestressed and non-prestressed.In this paper,the prestressed and non-prestressed structural forms of arch slab grain storehouse are compared and analyzed,and the design can be determined according to the specific requirements.
