Glass greenhouse construction design standards

Edit:Weifang Liwang Electric Co., Ltd.UpDate:2019-11-28

The structural design of the glass greenhouse must fully consider the growth needs of crops. The structural design of the large-scale multi-span glass greenhouse is more stringent than that of the ordinary greenhouse. The rationality of the design layout, the thermal expansion and contraction of the materials, and the accumulation of various data must be considered At the same time, the uniformity of the environment in the greenhouse needs to be considered. During the design and construction process, field visits should be conducted to make a reasonable layout.

The glass greenhouse construction process should be based on relevant standards, quality and processing accuracy, processing technology qualified materials, and timely correction during the installation process to reduce accumulated errors. At the same time, the installation of large-scale multi-span glass greenhouses must be equipped with hoisting and lifting equipment to ensure the quality and safety of the greenhouse installation. In addition, the basic embedding depth of the greenhouse needs to be determined according to the type of the greenhouse, such as the span, height and geological exploration data of the construction site. It is generally required to excavate the foundation to the old soil layer below the freezing line of the project location. It is also necessary to make good weather defense measures in advance, such as the setting of the snow melting system, to reduce the impact of natural disasters on production. The covering material of the large-scale multi-span glass greenhouse needs to be comprehensively considered taking into account the habit requirements of planting crops, local climatic conditions and user investment intensity, etc. Generally, it is recommended to use scattering tempered glass. Due to the high scattering characteristics of the covering material, the greenhouse There is no shadow inside, the light is even, the leaves are not burned, the greenhouse climate is milder, the plant light suppression is reduced, the plant bottom can absorb more sunlight, the plant bottom photosynthesis is increased, and the occurrence of gray mold on the plant bottom is reduced, which can improve the crop quality.
