Optimum size of greenhouse construction

"Greenhouse" is only the name of an industry and does not represent a type of greenhouse. The greenhouse industry is mainly divided into three structural forms: spring and autumn greenhouses, solar greenhouses and multi span greenhouses. These are also the three most common types of greenhouses in the market, but there is no national standard in the actual construction. Because the greenhouse belongs to a temporary building, its construction standards are basically based on industry standards.
The dimensions of greenhouse construction are not always designed according to the industry standards, and sometimes the construction site will be adjusted. The principle of actual design and construction is to maximize the use area of soil, which is also the core idea of greenhouse construction. However, the basic requirements of industry standards should also be followed, especially the basic requirements of wind load coefficient and snow load coefficient related to greenhouses. This can ensure the overall quality, reliability and safety of the greenhouse.
Basic standard for dimensional design of solar greenhouse
① Basic structure of solar greenhouse
As a unique greenhouse type in the north, solar greenhouse is mainly composed of wall, arc skeleton and covering materials (plastic film and thermal insulation quilt). Why is it a unique greenhouse type in the north? It has good thermal insulation. Generally, no heating equipment can be used, and production can also be carried out in winter. Its main wall forms are brick wall and earth wall structure. With the development of science and technology, other forms have emerged, but they are used less. The arc skeleton is mainly galvanized steel or oval pipe skeleton, and there are also flower racks. The covering materials are mainly plastic film and thermal insulation quilt, and its thermal insulation is mainly related to the thermal insulation quilt.

② Structural Design of Solar Greenhouse
In the design of solar greenhouse, it is mainly reflected in several aspects, including wall thickness and height, length and width. The length and span of the solar greenhouse is the core of the design. The minimum span is 6 meters. Generally, it is 8 meters or 10 meters. The thickness of the wall is mainly related to the thermal insulation, while the height of the solar greenhouse wall is mainly related to the span, that is, the angle of the arc skeleton. The larger the span, the higher the height of the back wall, so that the slope of the skeleton is large. It is more conducive to drainage, and the snow load and wind load coefficient of the construction greenhouse framework. The conventional length is about 100 meters, which is mainly the power problem of the matching quilt winder and film winder. It is also the case that the quilt winder is built at 200 meters long, but the quilt winder needs to be designed separately.
Basic standard for dimension design of multi span greenhouse
① Basic structure of multi span greenhouse
The main structures of the multi span greenhouse are strip foundation and independent foundation, steel structure skeleton and covering materials (glass or sunlight plate). Its foundation requirements are relatively high, especially for the fixed steel structure. On the basis of the foundation, it is necessary to do a good job of embedded parts, and then bolt the skeleton to ensure the stability of the skeleton. If the covering material is glass, its basic requirements are higher. Because the weight of the glass is relatively large, and the required strength of the skeleton is also relatively high.
▲ Standard multi span greenhouse
② Structural design of multi span greenhouse
The multi span greenhouses are basically rectangular, and the requirements in the industry are generally span, the conventional span is 9.6 meters, 10.8 meters, etc., and the maximum span is 16 meters. There is no requirement on the length of multi span greenhouse, as long as the construction site is large enough. In the construction of multi span greenhouses, the smallest has seen more than 300 square meters, and the largest has seen more than 10000 square meters.
Summary:
The greenhouse design above is the most conventional, but in terms of the development of the whole greenhouse industry and the different needs of the society, there have been irregular greenhouses, and new designs have been carried out according to the needs of customers, but the overall design cost will increase. If the corresponding cost increase due to special design type is acceptable, the special-shaped greenhouse can also be constructed.
