Embodiment Construction

[0037] Build a kind of fully assembled solar greenhouse suitable for the 44° north latitude area. Its walls and back slopes are mainly made of prefabricated large polystyrene particle foam concrete slabs for thermal insulation and heat storage. Its auxiliary thermal insulation material is extruded board with a thickness of 20cm. The heat storage material is a commercially available general heat storage plate with a thickness of 10cm. Its heat-absorbing material adopts commercially available general-purpose heat-absorbing film. The specifications of the wall materials of each layer are the same as that of the polystyrene particle foam concrete slab. The device adopts an integral light steel structure, and the arch frame is connected with the wall and the back slope frame as a whole. The indoor span is designed to be 12m, which is 4m wider than ordinary solar greenhouses, and belongs to large-span greenhouses. The front roof adopts advanced lighting angle at reasonable time....

Abstract

Provided is a fabricated land-saving energy-saving high-performance solar greenhouse and a building process thereof. The building structure that an overall light steel framework and a heat absorption and storage heat preservation multilayer composite encircling body are combined is adopted in the solar greenhouse. The standardized and modularized component assembly process is adopted during building of the solar greenhouse, and all components are connected through fixing parts. According to the greenhouse, the land can be saved by 50%, the room temperature can be improved by 4 DEG C or above, heating is not needed at northern latitude 43 degrees, and high performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of modern agriculture, and relates to a solar greenhouse, in particular to an assembled land-saving, energy-saving, high-performance third-generation solar greenhouse and its construction process. Background technique [0002] One of the directions of modern agriculture is to develop efficient planting represented by greenhouse facilities. In developed countries in Europe and America, represented by the Netherlands, the development of large-scale multi-span modern greenhouses is the main focus. However, due to its large investment and high energy consumption for heating, its development in my country is limited. my country mainly develops China's original solar greenhouses. Due to the small investment in solar greenhouses, no heating or only auxiliary heating, and sunlight as the main heat source, it has adapted to the national conditions and achieved unprecedented development, accounting for more than 80% ...
