防水下地用目地テープおよびそれを用いた防水工法

Japanese Patent JP7117731

B2

To provide joint tape for a waterproof substrate applied to connect aeration buffer sheets, which prevents a water proof layer or a top coat layer near an upper section of the joint tape for the waterproof substrate, especially, near both end parts in a width direction of the joint tape for the waterproof substrate from being cracked or being thinner in its thickness and prevents the waterproof layer and the top coat layer from being partially lifted up by ensuring between adjacent aeration buffer sheets distribution of gas generated from substrates through strengthening tight attachment and fastening of the joint tape for the waterproof substrate onto the aeration buffer sheets, in an aeration buffer method.SOLUTION: Joint tape 1 for a waterproof substrate attached on an overlapped part or an abutting part of end parts of a plurality of aeration buffer sheets 2 comprises: film-like material 10; reinforcement cloth 20 laminated on one side surface 10a of the film-like material 10; and an adhesive layer 30 on the other side surface 10b of the film-like material 10, wherein the film-like material 10 includes a first area 11 at a center part of the film-like material 10 and a second area 12 at both of sides of the first area 11 in a width direction, and has an opening 13 of the film-like material 10 in the second area 12.SELECTED DRAWING: Figure 3
