PROBLEM TO BE SOLVED: To provide a fixture and a sheet waterproof structure in which a fixing screw screwed into a building frame hardly comes off even when it is exposed to strong wind.SOLUTION: A fixture 120 of the present invention is used for fixing a waterproof layer 110 constituted by a waterproof sheet 112 and a substrate layer 111 to a surface of a building frame 100, and includes a flat plate 122 having a through hole 121, a bottom portion 123 confronting the through hole 121 and having a screw 124, and a connecting portion 125 connecting the bottom portion 123 and the flat plate 122. The relation of 0.90≤X/Y≤1.00 is satisfied, wherein a length of the connecting portion 125 is X mm and a thickness of the substrate layer 111 is Y mm. The connecting portion 125 is formed so that the width is gradually decreased from the flat plate 122 to the bottom portion 123.SELECTED DRAWING: Figure 2 |
