THERMAL BONDING TYPE COMPLEX WATERPROOFING METHOD USING PVC SHEET AND COMPLEX WATERPROOFING STRUCTURE USING SAME

摘要

The present invention relates to a thermal bonding type complex waterproofing method using a PVC sheet, which realizes a single coating layer in which two or more materials are mixed based on properties of a material used for a waterproof coating layer to provide a waterproof function corresponding to or improved more than an existing multilayer complex waterproofing structure with a relatively small number of coating layers or only a waterproof sheet layer, and realizes a process for finishing connection between the waterproof sheets and a connection portion therebetween in a scheme different from an existing process through a thermal bonding sheet to improve workability of the corresponding process and maximize a thermal bonding function of the thermal bonding sheet, and a complex waterproofing structure using the same. According to the present invention, the thermal bonding type complex waterproofing method using a PVC sheet comprises: a step of coating an asphalt coating material including a primer component and function on a surface to be waterproofed; a step of attaching a PVC complex sheet having an asphalt coating layer coated on one surface to a layer surface of the asphalt coating material in a state that the asphalt coating layer of the PVC complex sheet faces a layer of the asphalt coating material, and realizing attachment that end portion in a direction facing the PVC complex sheets with each other come in contact with each other; and a step of attaching a joint sheet to an area where the PVC complex sheets come in contact with each other through thermal bonding to combine the corresponding PVC complex sheets.;COPYRIGHT KIPO 2019
