Abstract
Description
[0001] This utility model is a divisional application for a prior utility model application with an application date of March 14, 2024, application number 2024204904856, and name “A production shed with a flexible tensioned shed support structure”. Technical Field
[0002] The utility model relates to the field of agricultural protected land production facilities, in particular to a solar greenhouse with a flexible tension wire shed surface supporting structure. Background Art
[0003] Greenhouses and solar greenhouses are both widely used agricultural protected production facilities. Their basic structure consists of a basic frame covered with a translucent greenhouse film. With the help of the greenhouse effect, through light, moisture retention, heat preservation and regulation of related gas concentrations, they artificially create a comprehensive environmental condition suitable for the growth and development of agricultural crops or with specific production functions, thereby realizing non-seasonal or non-regional planting, breeding or related agricultural production. Among them, the traditional basic skeleton of the solar greenhouse mainly includes bamboo and wood structure, reinforced concrete structure, steel frame structure and steel-bamboo mixed structure. With the rapid development of agricultural production, the application scope of solar greenhouses has been expanded to related fields such as flower breeding, fruit tree cultivation, forestry seedling cultivation, animal husbandry and aquaculture. The industrial development of these fields has put forward higher requirements for the structural span, spatial height and lighting adjustment function of the solar greenhouse. This large span and high space demand requires the production greenhouse to adopt a steel frame structure skeleton structure, and if necessary, a reinforced concrete foundation structure must be set up. As a result, the construction volume of the production greenhouse is increasing day by day, and the construction and maintenance costs are increasing. This unfavorable factor has become a "bottleneck" that restricts the further promotion of production greenhouses, and has a very adverse impact on the development of agricultural production. Therefore, it is necessary to study and improve the production greenhouse structure used in current production, use a new structural skeleton to replace the steel frame structure skeleton, solve the technical problems of large construction volume and high construction and maintenance costs of production greenhouses, and promote its further promotion and application.
