CUSHIONING SHEET AND HEAT-INSULATING WATERPROOF STRUCTURE AND HEAT-INSULATING WATERPROOF CONSTRUCTION METHOD USING CUSHIONING SHEET

摘要

PROBLEM TO BE SOLVED: To realize the prevention of a conduction to a heat-insulating material of a heat in the case of the heating of a fixture and the prevention of the movement of a plasticizer from a waterproof layer to the heat-insulating material at a low cost under a workability having a high efficiency in a heat-insulating waterproof structure in which the waterproof layer is fixed on the top face of a heat-insulating layer by melting an adhesive by the high-frequency heating of the fixture.;SOLUTION: The heat-insulating waterproof structure has a heat-insulating material layer laid on a backing, a cushioning sheet stretched on the top face of the heat-insulating material layer and the fixture dotted on the cushioning sheet and engaged with the backing. The waterproof structure further has a waterproof sheet laminated on the cushioning sheet, and an adhesive layer being melted by a high-frequency induction heating between the fixture and the waterproof sheet and fixing the waterproof sheet to the fixture. The cushioning sheet is composed of a heat-shielding layer for preventing an effect on the heat-insulating material of the heat generated in the fixture and a plasticizer shielding layer for preventing the translation of the plasticizer from the waterproof sheet to the heat-insulating material.;COPYRIGHT: (C)2005,JPO&NCIPI
