WATERPROOF SHEET AND CONSTRUCTION METHOD OF WATERPROOF SHEET
To provide a waterproof sheet that can be easily attached to a target corner or an inclined surface.SOLUTION: In the waterproof sheet 1 including a waterproof layer 2 and a constraining layer 3, the constraining layer 3 is provided with a notch 6 for exposing the waterproof layer 2. The constraining layer 3 includes a first constraining portion 7, a second constraining portion 8 disposed on one side with respect to the notch 6, and a third constraining portion 9 disposed on the other side with respect to the notch 6. The third constraining portion 9 is separated from the second constraining portion 8 farther than before the first constraining portion 7 is bent when the first restraint portion 7 is bent so that one end E11 and the other end E12 of the first restraint portion 7 approach each other. At this time, the waterproof layer 2 exposed from the notch 6 extends in the direction in which the third constraining portion 9 is separated from the second constraining portion 8.SELECTED DRAWING: Figure 4
【課題】対象のコーナーや傾斜面に対して容易に密着させることができる防水シートを提供する。【解決手段】防水層２と拘束層３とを備える防水シート１において、拘束層３に、防水層２を露出する切欠き６を設ける。拘束層３は、第１拘束部７と、切欠き６に対して一方側に配置される第２拘束部８と、切欠き６に対して他方側に配置される第３拘束部９とを有する。第３拘束部９は、第１拘束部７の一端Ｅ１１と他端Ｅ１２とが近づくように第１拘束部７が折り曲げられたときに、第１拘束部７が折り曲げられる前よりも、第２拘束部８から離れる。このとき、切欠き６から露出される防水層２は、第３拘束部９が第２拘束部８から離れる方向に伸長する。【選択図】図４
