Title:
SOLVENT CARRIER SHEET, SHEET WATERPROOFING STRUCTURE, AND ADHESION METHOD
Document Type and Number:
Japanese Patent JP2016069805
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a solvent carrier sheet capable of supplying a soluble solvent uniformly to a connected portion between a waterproof sheet and a resin sheet overlapped in a thickness direction of a sheet waterproofing structure, when fusing the sheets using the soluble solvent, and also of reducing cracking of the waterproof sheet when hit by a gust of wind, along with the sheet waterproofing structure installed using the solvent carrier sheet, and an adhesion method applied to installation of the sheet waterproofing structure that uses the solvent carrier sheet.SOLUTION: A solvent carrier sheet 80 is used in an adhesion method in which a waterproof sheet (first resin layer) 20 and a resin layer (second resin layer) 62 of a waterproof structure 10 are fused at a connected portion 64, is disposed between the waterproof sheet 20 and the resin layer 62, and discharges a soluble solvent therebetween when pressed. A bond strength after the adhesion satisfies an inequality A>B, where A is the bond strength at a portion 81 on a central side, and B is the bond strength at a portion 82 on a peripheral side.SELECTED DRAWING: Figure 2
