<p>PROBLEM TO BE SOLVED: To enhance workability for piping works by improving a piping band. SOLUTION: In this piping band with bolts, the bolts 7 are loosely supported in such a way as to be freely rotated so as to be formed into the piping band with bolts by letting bolt insertion holes 3 for one opposite fastening piece 2 in the piping band A be processed by press at its closely adjacent area, and letting the bolt insertion holes 3 be thereby plastically deformed. And furthermore, slip-out stopping ribs 5 for the bolts 7 are provided for one opposite fastening piece 2 to prevent the bolts 7 from being freely rotated when nuts are fastened.</p> |
