BAND-SHAPED MEMBER FOR HELICAL PIPE AND METHOD FOR REGENERATING EXISTING PIPE

A strip member is provided that can be made into a spiral pipe with an enlarged perimeter by being spirally wound. A first fitting portion 93 is disposed in one end portion of a cross-section orthogonal to an extending direction of a strip member 90 and a second fitting portion 94 is disposed in the...

description A strip member is provided that can be made into a spiral pipe with an enlarged perimeter by being spirally wound. A first fitting portion 93 is disposed in one end portion of a cross-section orthogonal to an extending direction of a strip member 90 and a second fitting portion 94 is disposed in the other end portion of the cross-section. A spiral pipe 9 is made by spirally winding the strip member 90 and fitting the second fitting portion 94 with the first fitting portion 93 preceding by one turn. The strip member 90 has a cross-sectional configuration in which a reference width direction W9connecting the first fitting portion 93 and the second fitting portion 94 on the cross-section is inclinable to an outer surface side toward the first fitting portion side when the strip member is wound. Preferably, a neutral weak axis LN9of the cross-section is inclined to an inner surface side with respect to the reference width direction W9toward the first fitting portion 93 side.
