With the rapid development of agriculture, modern agricultural construction is also constantly updated. The emergence of glass greenhouses has replaced traditional greenhouses. We should have seen common greenhouses. Generally, greenhouses are usually made of plastic materials. This is simple and practical maintenance equipment, using bamboo, steel, and other materials, and covering the plastic film to build an arched shed for the cultivation of vegetables and other crops. This kind of greenhouse is simple to create, convenient to use, and low in cost. However, with the development of agricultural modernization, glass greenhouses have also been used more and more in recent years. Let us analyze the structure of glass greenhouses together.
The bases of glass greenhouses are divided into two types: independent bases and strip bases. The former can be used for inner columns or side columns, and the latter is mainly used for sidewalls and inner partitions.
Before the foundation is planned, the geological data of the construction site should be carefully analyzed. In addition to the requirements of satisfactory strength, it should also have satisfactory stability and the ability to resist uneven settlement. The foundation connected to the support between the columns should also have satisfactory The effect of horizontal force transmission and spatial stability. The bottom of the greenhouse should be located below the frozen soil layer, and the heating greenhouse can consider the impact of heating on the freezing depth of the root base according to the climate and soil conditions.
2. Steel structure
The steel structure mainly includes the load-bearing structure of the greenhouse and the supports, connecting pieces, and solid pieces provided to ensure the stability of the structure. The steel structural materials are mainly cold-formed thin-walled steel and hot-rolled steel.
Cold-formed thin-walled steel
Because the greenhouse components are exposed to high humidity indoors for a long time, the structural components should be treated with anti-corrosion. Generally, hot-dip galvanizing is used for treatment. In order to ensure the anti-corrosion treatment effect, the components should be anti-corrosion operation after processing. It is not allowed to cut, sew, and weld the greenhouse components on-site. If there are a few on-site operations, they need to be treated with anti-corrosion reinforcement. Spray anti-corrosion paint on the processing or wound.
First of all, we need to pay attention to its sealing problem. This is a very important issue for glass greenhouses or other greenhouses. The sealing problem directly affects the energy consumption of the greenhouse. Carefully check the sealing. Whether the sealing degree of the parts and sealing strips is intact, and then there is the phenomenon of cracking, peeling, and aging of the rubber disposal part. The edge parts of the skylights and side windows must also be regularly inspected. If problems are found to be dealt with in time, this is the maintenance. The key to maintenance work. And pay special attention to the issue of tightness before the severe winter.
The second is the transparency of glass greenhouses. The investment intention of glass greenhouses is mostly used for the production of flowers and vegetables, or used in greenhouses with ornamental meanings such as scene greenhouses and ecological restaurants. Glass is not polluted. Under the circumstances, the lighting in the greenhouse is outstanding, which is very suitable for the growth and development of plants.
