Embodiment Construction

[0023] Such as figure 1 As shown, the construction method of the ultra-thin light-load heat preservation type solar greenhouse back slope of the present invention is carried out according to the following steps:

[0024] The first step, the construction of the load layer: use 4-6 strip steel plates 2 along the east-west direction to connect with the back slope frame of the greenhouse as the back slope support, and cover and fix a layer of PC board 1 on it;

[0025] The second step, the construction of the insulation layer: the first linoleum layer 3, the first plastic film layer 4, the grass thatch layer 5, the second plastic film layer 6, the second Linoleum layer 7;

[0026] The third step, the construction of the waterproof layer: laying the concrete layer 8, the styrene-butadiene-styrene rubber modified asphalt waterproof layer 9, and the aluminum foil layer 10 sequentially on the upper surface of the second felt layer 7 from bottom to top.

[0027] The thickness of the ...

Abstract

The invention discloses a method for building an ultrathin light-load heat preservation type solar greenhouse back slope. The method comprises the following steps of: 1, building a load layer, namely connecting 4 to 6 bar-shaped steel plates and a greenhouse back slope framework along a horizontal direction to form a back slope support, and covering and fixing a layer of polycarbonate (PC) board on the back slope support; 2, building a heat preservation layer, namely sequentially paving a first asphalt felt layer, a first plastic thin film layer, a straw mattress layer, a second plastic thin film layer and a second asphalt felt layer on the upper surface of the PC board from bottom to top; and 3, building a waterproof layer, namely sequentially paving a concrete layer, a phenylethylene-butadiene-phenylethylene rubber modified asphalt layer and an aluminum foil layer on the upper surface of the second asphalt felt layer from bottom to top. The method has the advantages that: 1, the total thickness of the ultrathin light-load heat preservation type solar greenhouse back slope is 140 to 180 millimeters, and is 1 / 3 of the thickness of the conventional greenhouse back slope; 2, the unit area ratio is small, so that the constant load is reduced; 3, the cross-flow heat dissipation is reduced, and heat energy cannot be conducted outwards; 4, longitudinal and transverse torsion, vibration and deformation can be resisted; and 5, the service life is prolonged.

Description

technical field [0001] The invention relates to a solar greenhouse in the agricultural field, in particular to a method for constructing the back slope of an ultra-thin light-load heat-retaining solar greenhouse. Background technique [0002] Agricultural facilities represented by solar greenhouses in northern my country have developed rapidly in recent years. The rapid development of facility agriculture has promoted farmers' income, agricultural efficiency and rural economic prosperity, especially accelerated the development of modern agriculture and high-efficiency agriculture. It has also promoted the adjustment of the agricultural planting structure and the transformation of the rural development mode. [0003] The back slope of the solar greenhouse (also known as the back roof) plays a very important role in the greenhouse structure. It not only plays a role in heat preservation, especially affects or determines the temperature at night and in continuous rainy weather, ...
