URETHANE WATERPROOF SHEET, MANUFACTURING METHOD OF THE SAME, AND WATERPROOFING METHOD BY URETHANE WATERPROOF SHEET
To provide an urethane waterproof sheet capable of preventing thermal expansion, preventing peeling from a substrate and deformation of a sheet joint, reducing burden on a seal to maintain a water cutoff effect, and in which the sheet itself can be easily cut using Tinman's snips or the like, and simple bending can be performed easily, a manufacturing method of the same, and a waterproofing method by the urethane waterproof sheet.SOLUTION: There is provided a molded sheet by an urethane resin which is a rectangular plate appropriate for stick, and an extension or expansion prevention layer 4 that binds urethane by a metallic mesh plate-shaped structure 5 is formed inside the molded sheet. At a waterproof construction site, a waterproof sheet is applied over a waterproofed surface using an adhesive layer formed by applying an urethane or urea-based adhesive.SELECTED DRAWING: Figure 1
【課題】熱伸びを抑制することができ、下地との剥離、シート接手の変形を抑制し、シールへの負担を低減して止水効果を維持でき、また、シート自体は金切り鋏等で容易にカットでき簡単な曲げ加工も容易であるウレタン防水シートおよびその製造方法およびウレタン防水シートによる防水工法を提供する。【解決手段】貼り込みに適した矩形平板であるウレタン樹脂による成形シートであり、金属網板状構造体５によりウレタンを拘束する伸長または膨張防止層４を内部に形成した。防水施工現場において、ウレタンまたはウレア系接着剤を塗布して形成した接着層を用いて、被防水面の上に防水シートを貼る。【選択図】 図１
