Embodiment Construction

[0007] The solar heat slow-release shed framework disclosed in the application of the present invention is made of cement sand slurry mixed with the following additives and then molded and solidified. One or more reinforcing steel bars 2 are embedded in the shed framework 1, and the outer surface of the shed framework is covered There is an outer layer 3, as shown in the accompanying drawings. The gravel of the cement-sand slurry is black granite crushed stone with a particle diameter of not more than 1-2cm, which is mixed according to the conventional proportion of cement-sand slurry. The additives include perlite and heat-conducting metal powder, the amount of perlite is 20-30% of the total volume of cement sand after adding perlite, and the amount of heat-conducting metal powder is 20-30% of the cement sand after adding perlite. 3-7% of the total weight. Perlite has many air pore structures, which play a role in heat preservation and heat storage in the mixed material. Un...

Abstract

The invention discloses a solar heat slow-release shed framework which is manufactured by the following steps of: internally embedding reinforced steel bars after mixing cement-sand slurry with additives, performing compression molding forming and solidifying. An outer layer covers the outer surface of the solar heat slow-release shed framework, and the additives comprise perlite and heat-conducting crushed metal powder. The solar heat slow-release shed framework disclosed by the invention is not only a supporting beam of a whole shed, but also an energy storage library of solar heat and a heat sink capable of preventing the temperature drop in the night; and in addition, a plurality of shed frames in a whole solar greenhouse can effectively restrain the trend of the temperature drop of the greenhouse in the night, thus crops planted in the greenhouse have more stable and more suitable growth environment.

Description

technical field [0001] The application of the present invention relates to a shed frame component of a solar greenhouse. Background technique [0002] Solar greenhouses are the most widely used in the planting of agricultural products, also known as greenhouses, especially in low-temperature seasons to provide off-season or off-season agricultural products, making a great contribution to enriching the "vegetable blue" of citizens. At night, the greenhouse needs to be covered with thermal insulation curtains to reduce the rate of heat loss as much as possible. The existing structures of greenhouses all rely solely on absorbing sunlight and heat energy during the day and keeping the thermal insulation curtain at night to prolong the space temperature of the greenhouse. However, in reality, it is difficult to withstand the temperature drop at night for a long time, resulting in the extension of the growth cycle and even damage to the seedlings. For this reason, growers will in...
