The waterproof sheet 30 is fixed by, for example, interposing an adhesive between the upper surface of the waterproof base panel 20 and the lower surface of the waterproof sheet 30 so that the adhesive covers the plurality of waterproof base panels 20. The sheet 30 can be fixed.

  As a method of installing the waterproof base panel 20 with respect to the waterproof base 1, a first step of bonding and fixing the posture holding member 10 onto the waterproof base 1 with the first adhesive 40, and a first extending portion 11 of the posture holding member 10 are provided. And a second step of bonding and fixing the waterproof base panel 20 onto the waterproof base 1 with the second adhesive 41 in an action posture to receive the posture holding action by the posture holding member 10.

  First, the first step is performed, and as shown in FIG. 2, the first adhesive 40 is interposed between the lower surface of the second extending portion 12 and the upper surface of the waterproof base 1, so that the posture holding member 10 is The adhesive 40 is bonded and fixed on the waterproof base 1 with one adhesive 40. Since the posture holding member 10 is a very small member compared to the waterproof base panel 20, the bonding and fixing operation is a simple operation. The first adhesive 40 is faster in drying than the second adhesive 41 and the time required for solidifying the first adhesive 40 is short. The work of adhering and fixing to the top can be performed smoothly in a short time. Since the second extending portion 12 is formed in a plate shape extending along the waterproof base 1, a sufficiently large bonding area can be secured and the posture holding member 10 can be appropriately bonded and fixed. . Here, with respect to the fixing position of the posture holding member 10, for example, as shown in FIG. 5B, the posture holding member 10 is fixed at positions corresponding to the corners of the rectangular waterproof base panel 20. Are previously positioned.

  Next, the second step is performed. At this time, as shown in FIG. 2, the posture holding member 10 is already bonded and fixed onto the waterproof base 1. The posture holding member 10 that is bonded and fixed has a posture in which the rod-shaped first extending portion 11 extends upward, and as shown in FIGS. 3 and 4, By pressing the waterproof base panel 20 from above, the waterproof base panel 20 can be pierced into the first extending portion 11. By piercing the waterproof base panel 20 into the first extending portion 11, the waterproof base panel 20 is subjected to a posture holding action by the posture holding member 10, and the posture holding member 10 holds the posture of the waterproof base panel 20.
