The present invention relates to a cover block for inserting a vinyl house, and more particularly, to a cover block for cooling a heat generated by the sun, which is installed so as to be assembled by covering the outer edge of a plastic house, And a heat insulating structure of the room by the cover block. In general, in low-lying areas such as urban areas or rivers, there is a vinyl house for farming regardless of the season while cultivating gardening. This is because a heat insulating jacket or the like is mainly used to maintain the heat insulation for tilling or the like in the vinyl house, and most of the heat insulating jacket is made of opaque material so that the outer surface of the vinyl house is covered with a driving device if necessary, It is to adjust the dose to the sun as a kick. Therefore, when the present invention will be described in detail, in the vinyl house to form an interior space for arable land by wrapping the sections of two or more aggregates 11 with vinyl 12 so that the upper section is formed in a convex portion 28 by curvature. , In order to cover the plastic inclined around the convex portion 28 of the vinyl house 10 to provide assembling, the curved frame 21 is provided with a plurality of two or more, both ends of the curved frame 21 Fixing string (29) for weaving and pulling (22), Fixtures 26 are coupled to the both ends 22 of the curved frame 21 through, and The fixing frame 29 and the curved frame 21, which is curved by the curved frame 21 is fixed to the plurality of two or more with the fixing table 26, the inner space (a) by winding with a vinyl body 24 Forming a cover block 20, The fixing ring 32 for weaving the fixing block 26 for the cover block 20 and the rope 30 in the interlocking fixing plate 26 are provided to bind to the prosecution 30. In addition, the fixing ring 32 for weaving the cover block 20 provided in the section of the roof plate 13 formed on both sides by the convex portion 28 and the fixing table 26 of
