The orientation of the plastic greenhouse is preferably extended in the north-south direction. In windy areas in spring and autumn, it must be extended in the direction of the wind so that the end face of the greenhouse is exposed to the wind. The sheds are arranged symmetrically, with the distance between two sheds not less than 1.5 meters and the distance between shed heads 1.5 meters, creating convenient conditions for transporting seedlings, drainage, ventilation and other operations. .Length The construction length of the all-steel frame plastic greenhouse can be determined according to the plot of land, and is preferably ~ meters (the length of the standard single-seat plastic greenhouse is meters).
.The span span is preferably .m., a single arch structure can meet the design needs, and a meter-long standard steel pipe can be welded into an arch frame. Each location can make appropriate adjustments based on topography and economic capabilities. If the span is too small, the relative investment cost will be too high. Steel materials will be wasted. If the span is too large, additional columns or truss structures need to be added, which will directly increase the investment.
3. Shoulder height, ridge height
The shoulder height of steel frame plastic greenhouses is generally designed to be ~.3 meters. For greenhouses used for planting taller crops such as fruit trees, the shoulder height can be increased to .~meter. At the same time, diagonal braces need to be installed at the legs and arch surfaces of the arch rods to increase the load-bearing capacity of the greenhouse. Ridge height: The ridge height of steel frame plastic greenhouses is generally .~3.3 meters. The vertical height difference between the ridge and shoulders of the greenhouse with a span of .m is preferably .m. First, the arch surface formed has a small reflection angle of sunlight and high light transmittance. The second is to make full use of the mechanical properties of the steel pipe and maximize the tensile and pressure-bearing properties of the arch rod. The third is to solve the problem of crops being damaged by dripping water caused by the shed surface being too flat.
The arch spacing refers to the horizontal distance between two adjacent arch poles, generally .~ meters. In areas where the wind is sheltered or the wind force does not exceed grade 1, the arch spacing should be no more than meters. In areas with strong winds, the spacing between arch poles should be no more than 3.0 meters.
