What are the structural characteristics of the multi-span greenhouse skeleton!
The wide application of greenhouses has changed the growth conditions of traditional plants, making it possible to grow crops all year round, bringing considerable income to growers. Among them, the multi-span greenhouse is a main greenhouse structure facility, which generally has a complex structure and relatively large investment.
The greenhouse frame is the main structure of the entire multi-span greenhouse. At the beginning of the design, it should be determined what kind of greenhouse frame to use according to the specific needs. Of course, different types of greenhouse frames have different structural characteristics. Below we will explain the multi-span greenhouse for you. Structural features of the skeleton:
The whole steel frame material is used as the skeleton of the greenhouse, and the main body of the greenhouse has a long service life, which can reach more than 20 years. But at the same time, it is necessary to pay attention to the anti-rust and anti-corrosion of the greenhouse frame. Generally, hot-dip galvanized steel frames are used.
The greenhouse frame has strong wind and snow load resistance. According to the local natural environment, natural conditions such as wind, rain and snow, select the appropriate skeleton and covering materials.
Multi-span design can be adopted, with large indoor space and high land utilization rate, suitable for large-scale planting and mechanized greenhouse operation. The span and bay can be selected. We have processed the largest greenhouse frame with a span of 16.0m and a bay of 10.0m. After a heavy snowfall, the frame of the greenhouse was intact and accumulated new experience for the use of the frame of the greenhouse.
Generally, the bolted greenhouse frame is used, which is convenient, economical and durable to install. If welding is used, the weld is easy to rust, and once rusted, it will greatly affect the service life of the greenhouse frame.
Therefore, when processing the greenhouse frame, it is necessary to adopt the method of perforated bolt connection as much as possible to avoid welding joints. The skeleton of multi-span greenhouses must be selected according to the actual environment, and the professional designers will conduct measurement and design to ensure that the constructed greenhouses are strong and durable.
