The role of the multi-span greenhouse
1. The rolling of the wall is not strong and the cut surface is not smooth
Practice has proved that the quality of the greenhouse wall will directly affect the length of its service life. In recent years, the construction of greenhouses is developing in the direction of higher, wider and no columns, which further requires the firmness and stability of the walls of the greenhouse.
2. The angle of the rear roof is small and the covering material method is incorrect
According to the company's years of construction experience, we will share the 5 steps of the correct rear roof construction method for the roof after we build the greenhouse:
1. The angle between the rear roof and the horizontal line can be determined according to the sun altitude angle at noon on the local winter solstice, generally 45~50°.
2. For the steel wire for laying garbage, because the bearing capacity of the "rear roof" is too large, it is necessary to densely lay the steel wire for garbage, and the steel wire is 8-10 cm thick.
3. Cover insulation
4. The soil starts from the end of the shed, and the excavator takes the soil, and then pushes the soil on the "rear roof" little by little, and uses iron drills and other tools for real shots for each 30 cm thick soil layer. Pay special attention to the height of the picture above, which should not exceed 40 cm at most.
5. "Slope protection".
3. The role of the multi-span greenhouse
The multi-span greenhouse is an economical greenhouse, which is very popular with users because of its beautiful curved shape and low cost. The arc-shaped roof is beautiful and generous, and the line of sight is smooth. The amount of steel used in the structure is small, and the thermal insulation performance is good.
