The widespread use of greenhouses has changed the growing conditions of traditional plants, making it possible to grow crops throughout the year and bringing considerable income to farmers. Among them, the multi-span greenhouse is the main greenhouse structure, the structure is generally more complicated, and the investment is relatively large. Large-scale multi-span greenhouses are usually used as ecological restaurants, flower markets, sightseeing exhibitions or scientific research greenhouses. The greenhouse skeleton is the main structure of the whole multi-span greenhouse greenhouse skeleton. At the beginning of the design, we should decide what kind of greenhouse framework should be used according to specific requirements. Of course, different types of greenhouse skeletons have different structural features. Here is the structure of the greenhouse skeleton:
1. The entire steel frame material is used as the greenhouse skeleton, and the main body of the greenhouse has a long service life, up to more than 20 years. But at the same time, it is necessary to pay attention to the rust and corrosion protection of the greenhouse frame, which generally adopts hot-dip galvanized steel frame.
2. The frame of the greenhouse has strong resistance to wind load and snow load. According to our local natural ecological environment, wind, rain and snow and other natural resource conditions, choose a suitable frame and cover different materials.
3. Multi-span design can be adopted, with large indoor space and high land utilization rate, suitable for large-area planting and mechanized Goshen greenhouse operation. Span and bay can be selected. I have constructed a greenhouse project with the largest span of 16.0m and bay of 10.0m. After a heavy snowfall, the greenhouse skeleton is intact and has accumulated new experience for the use of greenhouse skeleton.
Generally, a bolted greenhouse frame is used, which is convenient and affordable for installation and durable. If welding is used, welding is easy to rust. Once rusted, it will greatly affect the life of the greenhouse skeleton. Therefore, when processing the greenhouse framework, use hole bolts as much as possible to avoid welding. The frame of the multi-span greenhouse must be made of suitable materials according to the field environment, and professional designers should carry out measurement and design to ensure that the built greenhouse is sturdy and durable.
