<p>PROBLEM TO BE SOLVED: To provide a built-up pipe capable of maintaining a pipe body by fixing a pair of pipe halves facing each other and connecting the other pipe body similarly constituted as the pipe body, and further coping with adjustment of bending and length. SOLUTION: This pipe is formed by a pair of pipe halves 2, 3 forming the pipe body 1 and a pair of synthetic resin-made connection pipe half type bodies 5, 6 for fixing the pair of pipe halves 2, 3 for maintaining the pipe body 1 and connecting the other pipe body 1 similarly constituted as the pipe body 1. The pair of pipe halves 2, 3 extendingly provide pipe half parts for connection 9, 10 on both axial ends of pipe half bodies 7, 8. Flange-like protrusions 11, 12 are circumferentially provided on axial end outer peripheries of the pipe half parts 9, 10, and slits 13, 14 opened on the axial ends are formed. The pair of connection pipe half type bodies 5, 6 can engage with each other over the pipe body 1 and peripheries of the pipe half parts 9, 10 of the other pipe body 1, and flange-like lock protrusions 23, 24 for locking inside the flange-like protrusions 11, 12 are fixed on both the axial ends, and inserting pieces 25, 26 to be inserted into the slits 13, 14 are provided on both the circumferential ends.</p> |
