Structure of plastic greenhouse
1. Overall size of plastic greenhouse
Such plastic greenhouse have different structural dimensions in different countries. But on the whole, the span of the general plastic greenhouse is 6m ~ 12m, the opening is about 4m, and the eaves height is 3~4m.
2. Main structure
The main structure of plastic greenhouse is generally made of hot-dip galvanized steel pipe as the main bearing structure, factory production and on-site installation. Due to the light weight of the plastic greenhouse itself, the resistance to wind and snow loads is weak, so the overall stability of the structure should be fully considered.
The main structure of the plastic greenhouse must have the ability to resist at least 8 levels of wind, and the wind resistance is generally required to reach 10 levels.
The snow load carrying capacity of the main structure should be determined according to the actual snowfall conditions in the construction area and the winter use of the greenhouse. For use in the north, the design snow load should not be less than 0.35kN/m2.
For the annual operation of the plastic greenhouse, should also consider such as equipment weight, plant lifting weight, maintenance and other load factors.
