<p>PROBLEM TO BE SOLVED: To provide piping outlet part peripheral structure for a sheet waterproof structure that can provide excellent watertightness by positively jointing piping peripheral members arranged from a waterproof sheet to piping, to each other with sufficient strength even if the waterproof sheet is made of olefine resin and the piping is made of vinyl chloride. SOLUTION: This piping outlet part peripheral structure for the sheet waterproof structure is provided with an annular receiving board 10 and an annular pressing board 40 arranged at the outer periphery of the vinyl chloride piping 3; a jointing sheet piece 20 made of olefine resin and disposed between both boards 10, 40 so as to extend to the periphery of a piping outlet part of the waterproof sheet 5; a joint flange 30 made of vinyl chloride, jointed to the outer peripheral surface of the piping 3 and laminated on the jointing sheet piece 20 between both boards 10, 40; and erected bolts 15 and nuts 45 for pressing the pressing board 40 to the receiving board 10 side to clamp-hold the jointing sheet piece 20 and the joint flange 30 by both boards 10, 40. The outer peripheral edge part of the jointing sheet piece 20 is jointed to the piping outlet part periphery of the waterproof sheet 5.</p> |
