Warming-free solar greenhouse used in cold region and construction method thereof

Abstract

The invention discloses a warming-free solar greenhouse used in a cold region and a construction method thereof. The warming-free solar greenhouse comprises a rammed earth wall forming a main body frame of the solar greenhouse through enclosure, a foaming cement layer arranged on the outer side of the rammed earth wall, a heat insulation layer arranged on the inner side of the rammed earth wall, keels erected at the upper portion of the main body frame composed of the rammed earth wall, and a heat insulation layer, wherein the keels comprise frameworks and cross beams, the cross beams includetop beams and front end beams, the top beams are arranged at the top of the main body frame, and the front end beams are parallel to the top beams and are arranged on the front-end wall body of the main body frame; the frameworks include first frameworks and second frameworks, the first frameworks and the second frameworks are symmetrically arranged on two sides of the top beams, the first frameworks are slidingly connected with the front end beams, the tops and the bottoms of the first frameworks are both provided with clamping grooves, cover plates are laid on the second frameworks, solar cell panels are laid on the cover plates, the bottoms of the cover plates are provided with sealing plates, and the rear ends of the sealing plates are provided with extending portions. The constructionmethod is simple in construction process and efficient, energy is saved, the price is low, the service life of the greenhouse is long, and a heat storage function is good.

Description

technical field [0001] The invention relates to a solar greenhouse construction method, in particular to a solar greenhouse without heating in cold regions and a construction method thereof. Background technique [0002] In the greenhouse that is not heated indoors, the solar energy is absorbed through the back wall to realize heat storage and release, and maintain a certain indoor temperature level to meet the needs of vegetable crop growth. The back wall of the general greenhouse is an earth wall pressed by a chain rail car. The base of the back wall is 7 meters wide, and has good heat storage and heat preservation performance. However, the back wall occupies a large area and the land utilization rate is very low. The most important thing is this Practice has proved that this model has fatal weaknesses, such as low strength, easy to collapse when exposed to water, and easy to hide and breed parasitic pests in the untamped back wall; for greenhouses with brick back walls, t...

The back wall of the general greenhouse is an earth wall pressed by a chain rail car. The base of the back wall is 7 meters wide, and has good heat storage and heat preservation performance. However, the back wall occupies a large area and the land utilization rate is very low. The most important thing is this Practice has proved that this model has fatal weaknesses, such as low strength, easy to collapse when exposed to water, and easy to hide and breed parasitic pests in the untamped back wall; for greenhouses with brick back walls, the thickness of the bricks below the surface must be Only when the permafrost layer is larger than the local permafrost can meet the insulation requirements, the cost is expensive and the insulation effect is poor; most of the insulation layers of greenhouses today are laid on the roof with a layer of insulation film. A layer of insulation film is not only easy to break, but also the heat in the greenhouse is easy to penetrate. The thermal insulation layer is lost, and the thermal insulation effect is poor
