What kind of structure is a film greenhouse?

The film greenhouse is an irreplaceable infrastructure and is widely used in agriculture. The main structure of the greenhouse is mostly hot-dip galvanized steel pipe, which is stable and compressive, and can extend the service life of the greenhouse.

1. Thin-film greenhouses are also called plastic greenhouses. The greenhouses that use thin films as the main light-transmitting material are usually divided into single-layer membrane greenhouses and double-layer membrane greenhouses. The equipment is mostly round arch type. Its thermal insulation performance single-layer film greenhouse is mostly used in spring and autumn or in mild climate areas, and double-layer film is mostly used in northern China. Film equipment can be used in the flower and fruit planting market, etc.

2. The structure of the equipment is a gutter-linked multi-span multi-span pointed vault structure. It is mainly composed of foundation, column, main arch, auxiliary arch, gutter, external shading, internal shading, fan, wet curtain and other components. The surface of steel pipes used in the greenhouse will be treated with rust prevention. The main steel structure of the film greenhouse must be hot-dip galvanized and passivated. All link bolts and nuts that can be exposed to rainwater are galvanized. The normal service life of the main frame of the equipment can reach 15-20 years.

Among the loads on the film greenhouse, the load is the self-weight and the pretension generated by the rope used in the greenhouse. The variable loads include snow load, wind load, additional wind suction, additional wind pressure and crop hoisting load. Creating an excellent environment for vegetables and fruits can improve production efficiency and increase agricultural output, and obtain greater economic benefits.
