However, the present invention can also be applied to a device using such a fixing device. Thus, the fixing tool 3 is merely an example in the present specification, and any means may be used for fixing the groove-shaped frame 20 to the roof.

  The heat shield sheet 10 is composed of a synthetic resin sheet that has flexibility and stretchability and reflects and blocks / insulates solar heat. For example, as shown in this embodiment, the heat shield sheet 10 reflects and blocks solar heat and the like. A fabric sheet formed by knitting a resin yarn material colored in silver or the like to shield heat vertically and horizontally can be suitably used.

  The heat shield sheet 10 is fixed to a groove-shaped frame 20 fixed on the roof, and is stretched between the groove-shaped frames 20. In the present embodiment, the heat shield sheet 10 that is long in a strip shape in a direction orthogonal to the groove-shaped frame 20 is used. In addition, as shown in FIG. 3, the heat shield sheet 10 used in the present embodiment is knitted with vertical and horizontal resin yarn materials at portions other than both ends in the width direction (portions indicated by cross hatching). However, at both ends, the resin yarn material (weft yarn 10a) is not fixed by the warp yarn 10b (see a partially enlarged plan view surrounded by a one-dot chain line in FIG. 3). That is, the both end portions constitute the insertion portion 11 through which the shaft portion of the bolt 41 can be inserted.

  The groove-shaped frame 20 is made of a metal or a hard synthetic resin, and includes a groove portion 21 formed in a concave strip and a flange piece extending from the upper end of the groove portion 21 to both sides. The flange piece constitutes fixing portions 22 and 22 for fixing the pressing cover 30 disposed on the groove-shaped frame 20 with the heat shield sheet 10 interposed therebetween.

Each of the fixing portions 22 and 22 is formed with a bolt insertion hole 23 for a bolt for connecting to the pressing cover 30 corresponding to the width dimension of the heat shield sheet 10 to be attached. As shown in FIG. 1, the bolting can be fixed at both ends of the heat shield sheet 10 in the width direction.

  Further, the bolt 41 to be used is screwed into a nut 42 disposed above the holding cover 30 with the bolt head 41a facing down, and the lower surface of the fixing portion 22 is provided with a bolt head 41a when bolted. A bolt detent protrusion 24 is formed so as to prevent rotation.

  On the other hand, the pressing cover 30 is made of metal or hard synthetic resin, and the length dimension is substantially the same as the width dimension of the heat shield sheet 10, and the width dimension is substantially the same as the width dimension of the grooved frame 20. ing. Fixing portions 31 corresponding to the fixing portions 22 of the grooved frame 20 are formed at both ends in the width direction. Bolt insertion holes 32 corresponding to the bolt insertion holes 23 formed in the fixing portion 22 of the grooved frame 20 are formed at both ends in the longitudinal direction of the fixing portion 31.
