What Types Of Greenhouses Are There?
Sep 01, 2026
Plastic greenhouses can be divided into bamboo and wood structure multi-column greenhouses, bamboo and wood structure suspension beam hanging column greenhouses and steel frame columnless greenhouses.
(1) Bamboo and wood structure greenhouses generally have a span of 12 to 14 meters, a height of 2.2 to 2.4 meters, and a length of 50 to 60 meters. Usually, bamboo poles with a diameter of 3 to 6 cm are used as arch poles. The distance between the arch poles is 1 meter, supported by 6 rows of columns, and the distance between the columns is 2 to 3 meters. to increase support. The top 20 cm of the column is connected longitudinally with a tie rod. Buckle the film line between the two arches after the film is buckled. The advantages of this kind of greenhouse are that it is convenient to obtain materials, low cost and easy to construct. The disadvantage is that there are too many columns, serious shading, and inconvenient work. In order to reduce the number of columns, the 6 columns in each row of arches can be changed to 6 columns in every 3 to 5 rows of arch rods, and the arch rods without columns are supported by small hangers between the arch rods and the tie rods. In order to prevent the column from rotting, the cement prefabricated column is now used instead of the wooden pole as the column, and the steel wire rope is used as the tie bar. The shape and structure of the cantilever and hanging column greenhouses are basically the same as those of the multi-column greenhouses. This type of greenhouse application is more common.
(2) Steel-frame column-free greenhouses Steel-frame column-free greenhouses generally have a span of 8 to 12 meters, a height of 2.5 to 3.0 meters, and an arch spacing of 1 meter. Use 6-point galvanized pipe as the upper string of the arch, ?12 steel bar as the lower chord, ?10 steel bar for drawing and welding to form the arch, and the foot of the skeleton is welded on the ground anchor. At the lower chord, the ?14 steel bar is used as the horizontal tie bar. Weld the arch into one piece. In order to save steel, an arch frame with a lower chord is set up every 3 meters, and a 6-point zinc steel pipe is used as an arch rod in the middle, and two ?10 steel bars are used as diagonal braces. Lajin on. This kind of greenhouse skeleton is sturdy and durable, with few shading parts, convenient operation, can add a canopy, and buckle the middle shed for heat preservation and cold protection. Compared with the bamboo and wood structure, it has many advantages.
(3) A steel-bamboo mixed structure greenhouse is set up with a plane steel arch every 3 meters or so, and the steel or steel pipe is used as a longitudinal tie rod to connect the arch into one. Weld a short column every 1 meter on the tie rod, adopt the structure of suspension beam and hanging column, place 1 to 2 thick bamboo poles as an arch, and build a greenhouse with no column or less column structure. This type of greenhouse is an intermediate type between bamboo and wood structure greenhouses and steel frame structure greenhouses. It uses less steel and has no columns in the greenhouse, which can not only reduce construction costs, but also improve operating conditions and avoid shading by columns. It is a more practical structure. .
(4) Prefabricated galvanized steel pipe greenhouse The steel pipe prefabricated greenhouse has certain specifications, the general span is 6-8 meters, the height is 2.5-3.0 meters, and the length is 20-60 meters. The arch frame is connected by two thin-walled galvanized steel pipes. It is bent, the spacing between the arches is 50-60 cm, and the longitudinal connection is made of thin-walled galvanized steel pipes. All connections of the skeleton are fixed and connected with special clamps. In addition to the advantages of light weight, good strength, corrosion resistance, no column in the middle, good lighting, and convenient operation, this kind of greenhouse can be freely disassembled and assembled according to needs, moved the position, and improved the soil environment. Batch factory production. The disadvantage is the high cost. Such greenhouses are widely used in southern my country.
