<p>PROBLEM TO BE SOLVED: To provide a sheet water-proof method excellent in workability and mounting safety in an internal corner and capable of realizing a water-proof structure excellent in an elapsing reliability. SOLUTION: After bringing a fixed metal devide 4 into contact with an internal corner section 3 formed of a process for fixing a first water-proof sheet 5 laid on a flat section 1, the flat section 1 and a rise section 2, a second water-proof sheet 5' is vertically hung down to the internal corner section 3 from above of the rise section 2, in the lower part of the second water-proof sheet 5', first of all, part put on the fixed metal device 4 is thermally welded to the surface to be put, and then, part put on the upper surface of the first water-proof sheet 5 of the flat section 1 is thermally welded to the surface thereof to connect the first water-proof sheet 5 to the second water-proof sheet 5'.</p> |
