<p>PROBLEM TO BE SOLVED: To lay out plural pipes 12 different in diameter in a compact manner by eliminating the waste of piping space in the periphery of a pipe 12 having a small bore diameter. SOLUTION: Since crest and valley parts 18a and 18b of the same pitch are continuously formed at the base of each pipe bearer 10 regardless of inside diameter of a pipe bearing part 16, even in the case of combining plural pipe bearers 10 different in size to be used, the crest and trough parts 18a and 18b can be fitted between the pipe bearers 10. Accordingly, there is no positional shifting in the direction of continuous crest and trough parts 18a and 18b between the pipe bearers 10.</p> |
