CONSTRUCTION METHOD FOR HEAT-INSULATION AND WATER PROOFING OF ROOF STRUCTURE USING THE COMPOSITE SHEETS

摘要

PURPOSE: An insulation and waterproofing construction method of a roof structure using a composite sheet is provided to prevent delamination and an inflation of a polyurethane waterproofing sheet by smoothly discharging moisture under insulation and waterproofing composite sheets. CONSTITUTION: A bottom surface(1) of a concrete matrix is evenly treated. A primer(2) is coated on the upper part of the bottom surface of the concrete matrix, and a nonwoven fabric(3) which is bored is installed. Polyurethane(5) of a high viscosity is coated on the upper part of the nonwoven fabric. Self-adhesive composite sheets(4, 4') are installed on the upper part of the coated polyurethane with a regular gap(a). The polyurethane(6) is coated on the whole gaps and the whole composite sheets. An ultraviolet film layer is formed on the upper part of the polyurethane.
