To bend into a desirable bending radius so as to make piping possible by connecting together a pair of short pipes through a bendingly connecting fixture having an expansible bellows part so as to constitute a bendingly connected pipe construction.
This bendingly connected pipe 11 is constituted of a pair of short pipes 12 and a bendingly connecting fixture 21. The short pipe 12 is formed into the same section as a pipe body out of concrete and the like, similar to the pipe body of a piping. The bendingly connecting fixture 21 is constituted of a bellows construction body 22 and end plates 31, and fitted extending over both short pipes 12. The bellows construction body 22 is formed out of silicone rubber and the like by blow molding or the like so as to be full of elasticity. Terminal end edges 23 are formed on both end parts of the bellow construction body 22 so as to cover the outer circumferential part of the end plate 31, and locking projection parts 25 having lock claws 24 are formed on the inside faces. The locking projection part 25 are locked with the recessed parts 32 of the end plates 31, and both terminal end edges 23 of the bellows construction body 22 are fitted and fixed to the end plates 31. The end plates 31 are fastened with the short pipes 12 by bolts and nuts.
