INSULATION PAD FOR DOUBLE VINYL-LAYERED GREENHOUSES, DOUBLE VINYL-LAYERED GREENHOUSES USING THE SAME, AND ITS CONSTRUCTION METHOD

摘要

The present invention relates to a double greenhouse for culturing various crops. Provided is an insulation pad apparatus for a double greenhouse to construct the double green house. The apparatus comprises: an insulating material layer which maintains a space between double sheet layers overlapped on a steel frame at regular intervals, and in which an upper side is made of an insulating material tightly maintained on an upper sheet layer; and a fixing means which is located in a lower part of the insulating material layer, and integrally fixing and maintaining the insulating material layer along the frame. According to the present invention, as the insulating material layer can perfectly block a flow of air between the sheet layers, the double greenhouse of the present invention can effectively prevent a dust accumulation and a dew formation phenomenon in an air layer between the double sheet layers, and significantly increase an insulation effect of the double greenhouse. In addition, the insulating material layer of the insulation pad apparatus can effectively prevent a thermal bridge phenomenon between a frame of a steel pipe and the upper sheet layer due to a high insulation factor. Therefore, the double greenhouse of the present invention can prevent a heat leakage as a direct heat conduction phenomenon, connected to the upper sheet layer from the frame of the existing same steel pipe, is blocked. Accordingly, the insulation effect inside the greenhouse can be more excellently maintained, heating costs can be significantly reduced in winter season, and the double greenhouse can be quickly installed with low installation investment costs.
