<p>PROBLEM TO BE SOLVED: To develop a soundproof member for a drainpipe and a soundproof structure facilitating manufacturing, having an excellent mass-production property, reducing the amount of add materials, and easily being equipped in a state of responding to an elbow part by means of retrofitting to a drain on a constructing site. SOLUTION: A bend-shaped flexible soundproof sheet 1 has the width responding to the outer peripheral length of a drainpipe of an equipping subject, and wound about a direct pipe part by means of vertically attaching. A soundproof sheet for a drainpipe has a mark line 13 for removing a part which becomes slack when the soundproof sheet 1 is equipped to an outer periphery of a bending part of an elbow part, on the sheet 1. The soundproof sheet for the drainpipe is attached to the outer periphery of the drain having the direct pipe part and the elbow part by means of vertically attaching winding, after removing the part defined by the mark line 13 at the position responding to the bending part of the elbow part. Therefore, an equipping process can be accomplished, which can common use for the direct pipe part and the elbow part to avoid being separated, facilitate the control of quantity when manufacturing or constructing, and reduce the number of added parts.</p> |
