CONNECTION STRUCTURE AND CONNECTION METHOD FOR PIPING

PROBLEM TO BE SOLVED: To provide a connection structure and a connection method by which pieces of piping having weatherproof properties can be strongly joined to each other.SOLUTION: A connection structure 100 of piping includes: a pair of pieces of piping 1, 1 each having an inner layer part 11 formed into a tubular shape, and an outer layer part 12 integrally provided with the inner layer part 11 on the outer side of the inner layer part 11 and having higher weatherproof properties than the inner layer part 11; a piping joint part 20 formed on an end part 1Z of each piece of piping 1 and having the outer layer part 12 not provided but the inner layer 11 exposed; a joint 3 formed into a tubular shape and from both ends of which the respective piping connection parts 20, 20 of the pair of pieces of piping 1, 1 are respectively inserted; and an adhesive layer 4 provided between the piping connection part 20 and the joint 3.SELECTED DRAWING: Figure 1 【課題】耐候性を有する配管同士を強固に接合することができる配管の接続構造及び接続方法を提供する。【解決手段】配管の接続構造１００は、管状に形成された内層部１１と、内層部１１の外側に内層部１１と一体に設けられ、内層部１１よりも耐候性の高い外層部１２と、を有する一対の配管１，１と、各配管１の端部１Ｚに形成され、外層部１２が設けられず内層部１１が露出した配管接合部２０と、管状に形成され、一対の配管１，１の各配管接合部２０，２０が、両端部からそれぞれ挿入された継手３と、配管接合部２０と継手３との間に設けられた接着層４と、を備えることを特徴とする。【選択図】図１
