<p><P>PROBLEM TO BE SOLVED: To provide a work method for a sound insulating stair capable of enhancing the sound insulation of the stair portion, of simplifying the work, and of improving the finish accuracy by using a sound insulating backing members by applying the backing member at the time of stair reform work in response to a request for sound insulating performance for a space including the corridor. <P>SOLUTION: The sound insulating sheet 4 is adhered to the upper surface of an existing stair and fixed by tacker 6, a noise insulating board applied with an impact absorbing mat 5 to the bottom surface of the sound shielding sheet 4 for preventing lightweight impacts is fixed, thereafter, the sound insulating stair is built by installing treads 7 and remodeled risers 9. Also, in this stair remodeling method, the sound shielding sheet 4 to be laid on the upper surface of an existing stair is adhered so as to continuously cover the existing tread boards 1 and existing riser boards 3 throughout the whole length up to down. <P>COPYRIGHT: (C)2004,JPO</p> |
