PROBLEM TO BE SOLVED: To provide a sheet sandwiching device capable of strongly sandwiching upper-lower end parts in left-right side edge parts of a waterproof sheet in a well-balanced state.SOLUTION: A sheet sandwiching device 30 for longitudinally sandwiching a peripheral edge part of a waterproof sheet 21, comprises a sheet receiving material 40 provided along the edge of an opening part 2 over the side from at least below the opening part 2, a sheet pressing material 50 butted against the front of the sheet receiving material 40 and a connection metal fitting 65 for connecting these by straddling the sheet receiving material 40 and an upper end part of the sheet pressing material 50 and releasable in a single operation. The sheet pressing material 50 is longitudinally tiltably provided with its lower end part as the axis, and the sheet pressing material 50 tilts forward, so that the sheet pressing material 50 separates from the sheet receiving material 40, and the sheet pressing material 50 tilts backward, so that the sheet pressing material 50 is butted against the front of the sheet receiving material 40.SELECTED DRAWING: Figure 1 |
