Glass greenhouse structure and covering materials
Glass greenhouse is a new high-end agricultural production mode. After years of development, glass greenhouses have been widely used in agriculture, industry, tourism, catering and other industries around the world, becoming the most widely used and used greenhouse form in the world.
Advantages of glass greenhouse structure:
In the purlin-less roof system, the load on the glass directly acts on the longitudinal gutter of the greenhouse, and the gutter transmits the force directly to the columns or roof beam nodes. Therefore, the gutter bears the uniform distribution force from the roof system and the concentrated load of maintenance, etc., and the external force borne by the roof beam is mainly transmitted by the gutter.
High roof drainage efficiency: As the number of gutters in each span of the Venlo-type greenhouse is 2~4, compared with other types of greenhouses of the same span, the catchment area of each gutter is reduced by 60%~79%.
Glass greenhouse supporting systems: external electric shading system, internal electric shading system, internal thermal insulation curtain system, top electric window opening system, fan + water curtain forced ventilation and cooling system, water curtain outside electric window system, internal heating equipment, etc. ( Specific selection according to application requirements).
Glass greenhouse application scenarios: vegetable and flower planting seedlings, aquaculture greenhouses, leisure sightseeing greenhouses, ecological picking garden greenhouses, ecological restaurant greenhouses, leisure club greenhouses, high-tech display greenhouses, etc.
Venlo glass greenhouse covering materials:
Good safety performance: when the glass is damaged by external force, the fragments will become honeycomb-like obtuse-angled small particles, which are not easy to cause serious damage to the human body; high strength: the impact strength of tempered glass of the same thickness is 3-5 times that of ordinary glass , Bending strength is 3-5 times that of ordinary glass; Thermal stability: Tempered glass has good thermal stability, can withstand temperature difference 3 times that of ordinary glass, and can withstand a temperature difference of 300 ℃;
Double insulating glass
Double-layer hollow glass is beneficial to the lighting, light transmission, beautiful appearance and good visual effect of the greenhouse, especially in terms of heat preservation performance.
