Description

Greenhouse rod structure

Technical Field

The utility model relates to the technical field of greenhouse rod pieces, in particular to a greenhouse rod piece structure.

Background

The greenhouse is originally special equipment for vegetable production. With the development of production, the greenhouse is widely applied, and the greenhouse is used for potted flower cultivation, fruit tree production, forestry production, aquaculture and the like. Fruit tree production is used for cultivating grapes, strawberries, watermelons, melons, peaches, oranges and the like; forestry production is used for culturing forest seedling, ornamental tree and the like; the breeding industry is used for raising silkworms, chickens, cattle, pigs, fish fries and the like.

The main body frame of the greenhouse is formed by splicing and assembling greenhouse rod pieces, and the strength and the service life of each greenhouse rod piece are related to those of the whole greenhouse. In theory, the thicker the greenhouse rod piece is, the higher the strength (the larger the sectional area is, the more stable the structure is), but the cost is also increased continuously, and the difficulty of installation is increased due to the excessive weight. For this reason, greenhouse bars are usually hollow tubes, and the weight and cost of the bars can be reduced while meeting the requirement of the sectional area. Meanwhile, from the aspects of process difficulty and production efficiency, the existing hollow greenhouse rod piece is usually formed by rolling a strip-shaped steel plate into a column shape, and then welding two side edges of the steel plate together, so that the side surface of the rod piece is free of gaps.

Because the application environment of big-arch shelter is mostly cultivation, breed industry, has a large amount of moist steam in the unavoidable air, is limited by welding level's restriction simultaneously, probably has phenomenon such as rosin joint to and the mode of external welding leads to the solder joint directly to expose outside, and current big-arch shelter member is very easy corrosion, leads to the partial intensity of member to become low, and then influences the holistic intensity of big-arch shelter.
