<p><P>PROBLEM TO BE SOLVED: To provide a structure for joining waterproof sheets, in which an overlap portion substantially eliminates a step and forms a flat shape, even when the adjacent waterproof sheets are joined together while overlapping with each other, in the case where the plurality of waterproof sheets are laid and fixed on a substrate. <P>SOLUTION: The adjacent waterproof sheets overlap with each other; a recess 4 with a depth almost equal in dimension to the thickness of the downside waterproof sheet 3-1 is formed on the substrate side of the overlap portion 6; an edge 5-1 of the downside waterproof sheet 3-1 is housed in the recess 4; and an edge 5-2 of the other adjacent waterproof sheet 3-2 is watertightly joined thereonto. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
