Title:
WATERPROOF STRUCTURE WITH FIRE SPREAD SUPPRESSING LAYER
Document Type and Number:
Japanese Patent JP2021085209
Kind Code:
A
Abstract:
To provide a waterproof structure that prevents the combustion of the heat insulating material by reducing combustion of a burning gas generated from the heat insulating material and reducing the possibility of falling a fire source onto the insulation, in order to solve an existing problem that the flammable gas generated by the thermal decomposition of the insulation would burn for a long time, and that the fire sparks placed on the tarpaulin would fall onto the insulation, making it impossible to sufficiently prevent the insulation from directly igniting.SOLUTION: A waterproof structure comprising : a heat insulating material layer laid on a roof substrate; a fire spread suppressing layer laid on the heat insulating material layer; and a thermoplastic resin-based waterproof layer laid on the fire spread suppressing layer and exposed to a surface, wherein the fire spread suppressing layer is composed of at least a thermoplastic resin layer and an incombustible material layer, the thermoplastic resin layer is disposed on the heat insulating material layer side, and the incombustible material layer is disposed on the thermoplastic resin-based waterproof layer side.SELECTED DRAWING: Figure 1
