Greenhouse: can not underestimate the role of wind column
Greenhouse: can not underestimate the role of wind column
The main force that causes damage to greenhouses is wind, especially hurricanes or cyclones.
The end frame plays a stable role in the greenhouse.
When the wind directly affects the end frame, the force on the end frame is much greater than that on the middle frame.
Like a domino effect, 10 people stand in a row holding the same steel pipe. When an external force hits the first person, the others will fall.
Therefore, increasing the wind column can not only properly reduce the amount of material in the middle skeleton, widening the spacing; At the same time, also solved the end section window, vent, flue hole and other problems.
