摘要

PROBLEM TO BE SOLVED: To provide a repair waterproof structure of a roof floor, which is favorably applied to a parapet having no jaw part, without complicated construction at an internal corner.;SOLUTION: A repair waterproof structure of a roof floor having a parapet 1 includes a deformable sheet 6 which continuously covers an existing waterproof layer 4 over the area extending from the upper end face and the inner side surface of the parapet 1 to the planar roof floor part 3 in the vicinity of the parapet, and overlapping waterproof layer 7 on the sheet 6. The deformable sheet 6 is formed of a foam resin sheet. The foam sheet includes a foam layer of a polyolefin resin foam having inherent bubbles with an average aspect ratio (Dz (maximum diameter in parallel to sheet thickness direction))/(Dxy (maximum diameter in parallel to sheet width or length direction)) of 1.1 to 4.0, an expansion ratio of 5 to 30, and a compression strength of 2 kgf/cm² or higher, and a reinforcement layer disposed on one side thereof.;COPYRIGHT: (C)2013,JPO&INPIT
