Popularization of knowledge in the glass greenhouse industry

There are different construction models in the industry based on the size of span and bay, and they are also divided into different usage methods: vegetable glass greenhouses, flower glass greenhouses, seedling glass greenhouses, ecological glass greenhouses, scientific research glass greenhouses, three-dimensional glass greenhouses, irregular glass greenhouses, leisure glass greenhouses, intelligent glass greenhouses, and so on. Its area and usage can be freely adjusted by the greenhouse owner. Small ones can have a courtyard leisure style, large ones can reach a height of over 10 meters, a span of up to 16 meters, and a bay of up to 10 meters. The level of intelligence can reach one click control.

The structure of a glass greenhouse mainly includes the greenhouse foundation, greenhouse steel structure, and aluminum alloy structure.

1. Basic classification: There are two types of glass greenhouse foundations: independent column foundation and strip foundation. Independent foundations can be used for internal or side columns, while strip foundations are mainly used for side walls and internal partitions.

2. Design requirements: Before design, the geological data of the construction site should be carefully analyzed. Firstly, the geological survey report of the site (used for important large-scale greenhouse projects); The second is construction site testing (for general projects); Thirdly, based on experience and reference geological data from nearby projects (for small-scale projects). In addition to the requirements for strength, the foundation design should also have stability and the ability to resist uneven settlement. The foundation connected to the support between columns should also have the function of transmitting horizontal forces and spatial stability. The bottom of the greenhouse should be located below the permafrost layer, and the heating greenhouse can consider the impact of heating on the foundation freezing depth based on climate and soil conditions. Generally, the bottom of the foundation should be 0 Above 5 meters, the distance between the top surface of the foundation and the outdoor ground should be greater than 0 1 meter to reduce the exposure of the foundation and its impact on cultivation.
