Cable-membrane greenhouse and construction method thereof

Abstract

The invention provides a cable membrane greenhouse and a building method thereof. The cable membrane greenhouse comprises cable membrane supporting structures, cable membrane tension structures and a cable membrane enclosure structure. The cable membrane supporting structures extend in a horizontal linear shape. One or more groups of cable membrane supporting structures are arranged, and each group of cable membrane supporting structures comprises one or more cable membrane supporting structures. A plurality of cable membrane supporting structures are arranged on the same vertical face. The cable membrane tension structures extend in a horizontal linear shape, or extend in a heaving and dipping mode in the horizontal direction. The cable membrane enclosure structure is of a structure integrally formed by a plastic membrane and a plurality of parallel inhaul cables in parallel. The cable membrane greenhouse is more reasonable in structure, the windproof and heat preservation performance of the cable membrane greenhouse are improved through the cable membrane enclosure structure, the cable membrane supporting structures and the cable membrane tension structures, the cable membrane greenhouse is larger in space and span, and a ventilation structure is simple and easier to operate; meanwhile, great consumption of steel arch structures and membrane pressing structures are avoided, the great cable membrane greenhouse building cost is saved, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of greenhouse construction, in particular to a cable-membrane greenhouse and a construction method thereof. Background technique [0002] Greenhouses are used to cultivate plants that require light (such as fruits and vegetables) and fungi that do not need light (such as edible fungi), and can also be used for aquaculture and poultry and livestock breeding that only need scattered light. [0003] At present, the conventional technical means adopted in the field of greenhouse construction technology is: the technical combination of "plastic film support structure + plastic film + plastic film laminated structure + facade enclosure structure". Its plastic film support structure is an arched curved body composed of multiple steel arches arranged in parallel, or a steel wire grid planar body composed of multiple criss-crossing steel wires; its plastic film is a single structure, that is, it is not compounded wit...

AI Technical Summary

Problems solved by technology

These technical solutions correspondingly require a large amount of building materials, therefore, the construction cost of traditional greenhouses is often relatively high

[0007] Second, in order to prevent the plastic film from being damaged by the strong wind, the traditional greenhouse needs to be equipped with a lamination structure (for example, a lamination line); therefore, the construction process of the traditional greenhouse is cumbersome and complicated, and it is not easy to operate

[0008] Third, in the traditional technology, the steel wire grid plane is used as the support structure of the plastic film in the greenhouse. However, it is difficult to fit tightly between the plastic film and the steel wire grid plane. Frequent shaking and movement between the plastic film and the laminated net can easily cause wear of the plastic film, which in turn affects the performance stability and service life of the plastic greenhouse

[0009] Fourth, in the traditional technology, steel arches are used as plastic film support structures in greenhouses. Due to the limitation of "arch-span ratio", it is difficult to build large-span plastic greenhouses with steel arches within the acceptable range of production costs. Therefore, in the traditional technology, the steel arch surface body is used as the greenhouse of the plastic film support structure, and the "arch-span ratio" is smaller, which is difficult to meet the needs of agricultural production such as orchard greenhouses and fish pond greenhouses that require tall spaces.

[0010] Fifth, after the ventilation device of the greenhouse in the traditional technology is closed, only one of the four sides of the film in the ventilation device is connected to the greenhouse, and the other three sides are still separated from the greenhouse, which is easy to be blown by the wind, and it is easy to make the greenhouse The hot and cold air inside and outside convects, resulting in poor airtightness and poor thermal insulation of the greenhouse

[0011] Sixth, each ventilation device can only control the ventilation of one side of the greenhouse at most, so each ventilation device must be equipped with a separate power transmission device

Therefore, there are many greenhouse ventilation equipment in the traditional technology and the efficiency of ventilation management is low
