JOINT SEALANT AND FITTING STRUCTURE THEREOF
PROBLEM TO BE SOLVED: To provide a joint sealant and a fitting structure thereof that prevent leakage of sediment, retained water and others even in a case of displacement that equals to or exceeds a primary allowance.SOLUTION: A joint sealant 10 includes: a secondary water cutoff member 12 formed of an elastic material and having both edges fixed on caissons 51, 51 placed adjacent to each other on both sides of a joint part 52, and an excess length part 12a that prevents leakage from a part between the caissons 51, 51; and a primary water cutoff member 11 disposed on one side of the secondary water cutoff member 12, having both edges fixed on the caisson 51, 51 on both sides of the joint part 52, and preventing leakage while allowing displacement between the caissons 51, 51. When displacement is up to a primary allowance set, the first water cutoff member 11 allows the displacement and restricts displacement of the excess length part 12a, and when displacement exceeds the primary allowance, the excess length part 12a allows the displacement.SELECTED DRAWING: Figure 4
【課題】１次許容量だけでなく１次許容量を越えた変位量に対しても土砂、保有水などの漏洩などを防止できる目地材およびその取付構造を提供する。【解決手段】目地材１０は、弾性素材によって形成されて目地部５２を跨いで隣接するケーソン５１，５１に両端部が固定されケーソン５１，５１間の漏洩を防止する余長部１２ａを有する２次止水部材１２と、２次止水部材１２の一方側に設けられて目地部５２を跨いでケーソン５１，５１に両端部が固定されケーソン５１，５１間の変位を許容して漏洩を防止する１次止水部材１１と、を備え、設定した１次許容量の変位までは、１次止水部材１１で変位を許容して余長部１２ａの変位を規制し、１次許容量の変位を越える変位量に対しては、余長部１２ａにより変位を許容可能に構成する。【選択図】図４
