  The arch receiver 7 is made of an elastic synthetic resin, and a plurality of the arch receivers 7 are attached on the pair of support pipes 5 at predetermined intervals so as to face each other. Both ends of the arch support 7 are supported by an arch bar 8 made of an elastic synthetic resin in a state of being curved upward. A heat insulating sheet (not shown) is supported on the arch bar 8.

  As shown in FIG. 3 to FIG. 5, the arch receiver 7 includes a cylindrical portion 9 that receives the tip portion of the arch bar 8, a band portion 10 that wraps around the outer periphery of the support pipe 5, and tightens the band portion 10. And a head portion 11. The cylindrical portion 9 opens upward so that the tip end portion of the arch bar 8 can be received in a substantially vertical direction when mounted on the support pipe 5. The band part 10 extends in the radial direction from the outer periphery of the upper part of the cylindrical part 9, and has a longitudinal engagement tooth row 10a on one surface. The head portion 11 is provided at the base portion of the band portion 10, and engages in a ratchet manner with an opening portion 11 a that penetrates the distal end side of the band portion 10 that circulates the support pipe 5 and an engagement tooth row of the band portion 10. And a ratchet claw 11b for preventing the band portion 10 from coming off from the opening 11a.

  As shown in FIG. 6, the support leg 3 includes an upper leg 12 made of a steel pipe material such as a single pipe, and an adjustment leg 13 that receives the lower end of the upper leg 12 and supports it at an interval on the ground. It comprises. The adjustment leg 13 includes a base 14, a screw rod 15, an adjustment nut 16, and a receiving bracket 17. The base 14 is disposed on the ground. The screw rod 15 stands vertically on the base 14. The adjustment nut 16 is screwed to the screw rod 15 and adjusts the height position of the receiving bracket 17 by the screwing position. The bracket 17 is positioned on the adjustment nut 16 and is externally inserted on the screw rod 15 so as to be movable up and down relatively. The lower end of the upper leg is received so that the height position can be adjusted.
