林用钢拱架塑料大棚的结构设计研究

STUDIES ON THE DESIGN OF PLASTIC SHED WITH STEEL ARCH

根据林区育苗生产的需要,本文对塑料大棚棚型的选择,材料及结构尺寸的确定进行了设计计算。并对试制生产的棚体结构进行了野外生产考验。认为该设计方案是合理的,其强度、刚度及稳定性均满足要求。

The shape, material and structure dimensions of plastic shed used for growing seedlings was designed. It is proved that the design is feasible and the strength, rigidity and stability of the structure are all qualified for the construction standards in working circles.
