Not only does it have excellent sound absorption properties due to the small sound absorption holes, but it also has excellent sound insulation properties due to the sound insulation sheet.It can maintain sound absorption properties without reducing sound insulation properties, and can satisfy both sound insulation and sound absorption performance. It is something. Moreover, the sound insulation sheet can reinforce the fiberboard, giving it excellent strength, and since the sound insulation sheet is already attached to the fiberboard, there is no need to use any special sound insulation material as a base during installation. It is something. Furthermore, the side ends of the pair of sound-absorbing and sound-insulating building boards are connected to each other by the fitting of the fitting protrusion and the fitting recess, and on at least one side from the fitting protrusion side to the fitting recess side,
In the case of a fitting convex part, the sound insulating sheet is extended so as to protrude from the root of the convex part, and in the case of a fitting recess, it protrudes from the tip edge, and the extending part of the sound insulating sheet is at least connected to the root of the fitting convex part and the fitting concave part. The extension of the sound insulating sheet is sandwiched between the joints, which are the fitting connection parts of both sound absorbing and sound insulating building boards, creating a gap at the connection part. At the same time, the extended portion of the sound insulating sheet is interposed in the thickness direction of the sound absorbing and sound insulating building boards, so that the joint portions of both sound absorbing and sound insulating building boards can be prevented from deteriorating the sound insulation properties of the joint portions by the extended portions of the sound insulating sheet. Because of its excellent sound insulation properties, this construction method is particularly suitable for piano rooms and bedrooms in ordinary homes, offices in factories and buildings, etc. In addition, it is possible to prevent the sound insulation at the joint from deteriorating simply by interposing the extension of the sound insulation sheet at the joint and fitting the fitting protrusion and the fitting recess. There is no need to use any members, and workability can be improved. In addition, the extension of the sound insulation sheet functions to eliminate gaps caused by dimensional errors between the fitting protrusion and the fitting recess, and furthermore, the extension of the sound insulation sheet acts as a cushion for the fitting part. It also serves to protect the fitting protrusion and fitting recess from chipping and cracking.
