Abstract
The utility model provides a kind of sound-absorbing ceiling, it include dope layer, sound absorbing layer and sheet metal layer, the dope layer is set to the outer layer of ceiling, it is honeycomb coating and spray attachment is on sound absorbing layer, for reinforcing sound-absorbing, the sound absorbing layer and sheet metal layer perforation are opposite, for absorbing the sound imported by sheet metal layer.Sound wave enters dope layer by honeycomb, to the first sound absorbing layer absorbing sound and lowering noise after one layer of filter sound, it absorbs sound after two layers of filter sound to sheet metal layer, again to the second sound absorbing layer sound-absorbing, the sound-absorbing of multilayer makes acoustic ceiling show efficient sound-absorbing effect, this acoustic ceiling is suitable for sound-absorption requirement required for Code in Hazardous Special Locations.
Description
Technical field
The utility model relates to building material technical fields, refer in particular to a kind of acoustic ceiling.
Background technique
Now suspended ceiling in the market mainly has metal ceiling and two kinds of nonmetallic smallpox, and plasterboard is exactly nonmetallic
One of smallpox, higher, the non-good sound-absorbing material of actual plasterboard density, but just to have base by puncturing technique
This acoustical absorbance properties, and what is generally used currently on the market is also this knot combined by puncturing technique and glass fibre cotton
The product of structure, and the scarce limit of this product is that sound-absorbing effect is poor, and the requirement of special sound-absorbing place material requested is not achieved.
The utility model is in Patent No. 201621196010.8, on the basis of a kind of entitled patent of acoustic ceiling
It improves, enhances sound-absorbing effect.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of simply Novel acoustic board for easily making, structure and set
Meter principle has been fully met to requirement required for sound-absorbing place.
To achieve the above object, the utility model uses following technical scheme:
A kind of sound-absorbing ceiling, includes dope layer, sound absorbing layer and sheet metal layer, and the dope layer is set to ceiling
Outer layer, be honeycomb coating and spray attachment on sound absorbing layer, for reinforcing sound-absorbing, the sound absorbing layer and sheet metal layer perforation are opposite,
For absorbing the sound imported by sheet metal layer.
Preferably, the sound absorbing layer includes the first sound absorbing layer, is set between dope layer and sheet metal layer.
Preferably, the sound absorbing layer further includes the second sound absorbing layer, set on the other end of sheet metal layer.
Preferably, the sheet metal layer includes several perforation, and the perforation is in honeycomb longitudinal arrangement, wears sound effectively
Thoroughly, reach preliminary filtering function.
Preferably, the sound absorbing layer is nonwoven sound-absorbing layer of cloth, for dust-proof and sound absorption.
Compared with prior art, a kind of sound-absorbing ceiling of the utility model, realizes dope layer, sound absorbing layer, plate
Effective combination of layer is absorbed sound by different size sound-absorbing Channel filtration, enhances the performance of absorbing sound and lowering noise, and make all directions
Sound can be filtered uniformly and effectively, and efficient sound absorption qualities are shown.The nonwoven sound-absorbing cloth that sound absorbing layer uses is of new generation
Environment-friendly materials, it is quite prominent in the function of sound-absorbing waterproof.The manufacturing technology of this acoustic ceiling is simple and clear, easy to operate, hangs
After dress, sound wave enters dope layer by honeycomb, to the first sound absorbing layer absorbing sound and lowering noise after one layer of filter sound, after two layers of filter sound
It absorbs sound to sheet metal layer, again to the second sound absorbing layer sound-absorbing, the sound-absorbing of multilayer makes acoustic ceiling show efficient sound-absorbing effect,
This acoustic ceiling is suitable for sound-absorption requirement required for Code in Hazardous Special Locations.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of sound-absorbing ceiling of the utility model.
Specific embodiment
Referring to Fig. 1, the utility model provides a kind of sound-absorbing ceiling, indoor or special sound-absorbing place is risen
It include dope layer 1, sound absorbing layer 2 and sheet metal layer 3 to sound-absorbing effect, the dope layer 1 is set to the outer layer of ceiling, is
Simultaneously spray attachment is on sound absorbing layer 2 for honeycomb coating, and for reinforcing sound-absorbing, the sound absorbing layer 2 is perforated with sheet metal layer 3 relatively, for absorbing
The sound imported by sheet metal layer 3.
The sound absorbing layer 2 includes the first sound absorbing layer 21, is set between dope layer 1 and sheet metal layer 3.
The sound absorbing layer 2 further includes the second sound absorbing layer 22, set on the other end of sheet metal layer 3.
The sheet metal layer 3 includes several perforation, and the perforation is in honeycomb longitudinal arrangement, penetrates sound effectively, reaches
Preliminary filtering function.
Fill hard macromolecule layer in the perforation periphery of the sheet metal layer 3.
Hard macromolecule plays the role of reinforcing to the surface layer of ceiling, and impact resistance is stronger than general material, together
When ceiling can be prevented to be distorted, misalignment；The length of perforation is slightly long, and when sound wave passes through perforation, friction energy occurs with hole wall
The sound energy of fraction is lost.
The sound absorbing layer 2 is nonwoven sound-absorbing layer of cloth, for dust-proof and sound absorption, has good sound-absorbing effect, is day
Right material, it is avoidable to generate the chemical substance being harmful to the human body and recyclable.
Above-described embodiment only expresses a kind of embodiment of the utility model, and the description thereof is more specific and detailed, but simultaneously
Therefore it cannot be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection scope of utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
