Description
Technical field
The utility model relates to a kind of sound-absorbing furred ceiling, is applicable to the finishing field.
Background technology
In the interior decoration of large public building, all will take into full account the sound-absorbing effect in whole space, furred ceiling need design the use acoustic finishing material, to satisfy the acoustics requirement.In the present dwelling house design, the fado of doing that floor adopts is that concrete floor adds plaster skin coat.Because the concrete floor rigidity is strong, effectiveness in vibration suppression is poor, so impact sound sound insulation is very poor.
The utility model content
The technical problem that the utility model solves provides a kind of sound-absorbing furred ceiling, solves the bad problem of traditional furred ceiling sound insulation.
The utility model comprises polyester fiber abatvoix, acoustical cotton, suspension hook, suspension rod, concrete prefabricated board, waterproofing mortar surface layer.Polyester fiber abatvoix thickness is 60～80mm; Polyester fiber abatvoix top is provided with acoustical cotton, and the polyester fiber abatvoix is connected with suspension rod through suspension hook, and the suspension rod diameter is 12mm; Suspension rod is T-shaped and is suspended on above the concrete prefabricated board; Be the waterproofing mortar surface layer above the concrete prefabricated board, waterproofing mortar intensity is M7.5, and thickness is 15mm.
The utility model sound insulation value is good.
