Large Space Hydroponic Greenhouse Venlo Type Glass Greenhouse For Tomato
Product Description
The Venlo structure is a popular structure at present. This structure uses a horizontal truss as the main load-bearing member and forms a stable structure with the column. The horizontal truss and the column are consolidated, and the connection between the column and the foundation is hinged. The horizontal truss bears 2 or more cabin surfaces. The traditional Venlo-type structure supports 2-4 3.2m span hut faces on each horizontal truss, forming standard 6.4m, 9.6m, 12.8m span greenhouses. The roofing load-bearing material of this structure is selected from aluminum alloy materials, that is, the roofing structure material and glass inlay material. In the structural calculation, due to the great difference in the strength of aluminum alloy and steel, the aluminum alloy roofing material is calculated separately according to the triangular arch structure, and the lower horizontal truss and column form a new force system, and then calculated separately. Recently, the traditional Venlo-type structure has been improved in China, changing the traditional 2m small span to a 3.6m or 4.0m small span. Increased, the roof bearing structure using pure aluminum alloy material is not strong enough. Therefore, the roof load-bearing members have also been changed to small-section square tubes, and the dual role of traditional aluminum alloys has been simplified to only play a role of glass inlay. In this way, the cross-sectional size of the aluminum alloy material can be reduced, and the amount of aluminum alloy can be reduced. However, in the calculation of the strength, the roof member and the horizontal truss column should be combined to form an overall structure calculation model for internal force analysis and strength verification.
Feature
1.The top and sides of the cost of the smart glass greenhouse are mainly made of special aluminum profiles.
The operation and connection of these materials not only make the appearance of the entire greenhouse more beautiful, the visual effect is smooth,
Moreover, it has good stability and strong anti-snow ability.
2 .: The cover material of the smart glass greenhouse is domestic single-layer float glass or double-layer hollow
Glass, both types of glass have good light transmission properties, thus creating more favorable photosynthesis for crops
conditions of
3. Since special glass is used as the main material of the greenhouse, then no matter how time is pushed
Shift, it will not change, because this glass has the characteristics of high strength and corrosion resistance
The service life of the greenhouse is also increased, and the glass has good flame retardancy.
