A large-span high-strength conjoined greenhouse

Abstract

The invention discloses a large-span and high-strength one-piece greenhouse which is composed of a plurality of single greenhouse bodies. Each single greenhouse body comprises a single greenhouse framework, wherein the single greenhouse framework is composed of an arched ceiling and supporting frames on the front side and the rear side of the single greenhouse framework, a covering material is distributed on the arched ceiling, the arched ceiling is composed of steel strands which are longitudinally and transversely distributed, each supporting frame is a fence structure composed of a plurality of supporting stand columns and transverse connection rods, the supporting stand columns on the front side of the single greenhouse body correspond to the supporting stand columns on the rear side of the single greenhouse body one to one, one end of each longitudinally-distributed steel strand is fixedly connected with the corresponding supporting stand column on the front side of the single greenhouse body, and the other end of each longitudinally-distributed steel strand is connected with a tension mechanism installed on the supporting stand columns on the rear side of the single greenhouse body. The large-span and high-strength one-piece greenhouse is large in span, low in cost and convenient to build, the height and inclination angle of the ceilings can be conveniently adjusted, and the large-span and high-strength one-piece greenhouse is suitable for large-scale mechanical production operation in the one-piece greenhouse; meanwhile, the bearing force is strong, the large-span and high-strength one-piece greenhouse can recover to the original shape in time when deforming under the effect of external force, and the capacity of the one-piece greenhouse for bearing natural disasters again is increased.

Description

technical field [0001] The invention relates to an agricultural production greenhouse, in particular to a large-span high-strength conjoined greenhouse. Background technique [0002] At present, traditional vegetable greenhouses have been widely used in agricultural production. However, the existing vegetable greenhouses have a single structure and function, and most vegetable greenhouses only exist in the form of single sheds (vegetable greenhouses have only one single shed skeleton). If the design is unreasonable, it is often not convenient for the height and inclination angle of the arched roof, and it cannot reasonably solve the problem of the span of each individual shed and the bearing capacity of the entire shed. For this reason, during the use of conjoined greenhouses, it is generally necessary to install a large number of support rods inside the shed body of the conjoined greenhouse, which not only has higher requirements for the flatness of the ground inside the s...

However, the existing vegetable greenhouses have a single structure and function, and most vegetable greenhouses only exist in the form of single sheds (vegetable greenhouses have only one single shed skeleton). The design is unreasonable, often inconvenient for the height and inclination angle of the arched roof, and cannot reasonably solve the problem of the span of each individual shed and the bearing capacity of the entire shed

For this reason, during the use of conjoined greenhouses, it is generally necessary to install a large number of support rods inside the shed body of the conjoined greenhouse, which not only has higher requirements for the flatness of the ground inside the shed body, but also increases the The complexity of the overall structure and the cost of production input and later maintenance costs. More importantly, the entire conjoined greenhouse can only be suitable for manual planting operations, which is difficult for large-scale and mechanized production inside the greenhouse; at the same time, After the existing conjoined greenhouses are built, the structure is fixed and cannot be adjusted. When the conjoined greenhouses are deformed due to thermal expansion and contraction or natural disasters such as strong winds and heavy snow, they cannot be restored to their original shape, and their resistance is greatly reduced. expected external forces
