JOINT BACKER AND JOINT WATER CUTOFF STRUCTURE
PROBLEM TO BE SOLVED: To provide a low-cost joint backer that prevents blocking of a ventilation layer formed on an indoor side of an external wall surface material, along with a water cutoff structure using the joint backer.SOLUTION: A joint backer includes a backer part 31 that supports a rear surface side of a sealant 4 embedded in a horizontal joint 2 formed between exterior wall surface materials 11 that are adjacent in a vertical direction, and a lip part 32 formed on both sides of the backer part 31, to be bendable with regard to the backer part 31. The lip part 32 may be detached when torn by a hand, and elastic restitutive force is generated in the lip part 32 that remained, when the remnant lip part 32 is bent and inserted into the horizontal joint 2. The remnant lip part 32 spreads due to the elastic restitutive force, and is hooked on a corner on a rear side of the exterior wall surface material 11.SELECTED DRAWING: Figure 2
【課題】外壁面材の屋内側に設けられる通気層が塞がれるのを防止できる構造を低コストで実現できる目地用バッカーおよびこの目地用バッカーを用いた目地止水構造を提供する。【解決手段】上下に隣り合う外壁面材１１の間に形成される横目地２に充填されるシーリング材４の裏面側を支持する部位となるバッカー部３１と、このバッカー部３１の両側で当該バッカー部３１に対して折り曲げ可能に形成されたリップ部３２とを有しており、上記リップ部３２が手で裂かれることで分離可能であり、分離されずに残されたリップ部３２が折り曲げられて上記横目地２に入れられることで上記残されたリップ部３２に弾性復元力が生じ、上記残されたリップ部３２が上記弾性復元力で広がって上記外壁面材１１の裏の角部に引っ掛かる。【選択図】図２
