Plastic greenhouse-greenhouse construction

Greenhouse construction - plastic greenhouse

 

The large-scale multi-span plastic greenhouse in the last decade and the rapid development of a greenhouse type. Compared with glass greenhouse, it has a light weight, small skeleton material with less structural parts shading rate, low cost, long life and other advantages, its environmental regulatory capacity can basically achieve the same level of the glass greenhouse, plastic greenhouse user to accept capacity worldwide is far higher than the glass greenhouse has become the mainstream of the development of the modern greenhouse.

 

Plastic greenhouse structure

 

The overall size of the plastic greenhouse

 

Such greenhouse in different countries with different dimensions of the structure. But overall, the Universal greenhouse in the span of 6 ~~ 12m bay in about 4m Eave height 4m. Based multi-span greenhouse natural ventilation, the joint use of the side windows and roof windows, greenhouse maximum width should be limited to within 50m best about 30m; mainly mechanically ventilated greenhouses, greenhouse maximum width expanded to 60m, but it is best limited to about 50m;, it is best to limit the length of the greenhouse, but there is no strict requirements within 100m.

 

2 of the main structure

 

Plastic greenhouse main structure generally as the main load-bearing structure with hot-dip galvanized steel, factory production, on-site installation. Due to the the plastic greenhouse light weight, wind, snow load resistance is weak, so the stability of the whole structure must be fully considered, generally want to set the vertical bracing indoor cross or second bay, in the greenhouse should consider setting up the necessary space to support the external structure as well as on the roof. Best oblique support anchoring on the basis of the formation of the space force system.

 

The plastic greenhouse main structure at least anti-8 wind capacity, general requirements for wind resistance up to 10.
