A kind of noise control damping Acoustic barrier plate
The utility model belongs to building material field, and in particular to a kind of noise control damping Acoustic barrier plate.
In the market on such as diesel engine, pump group, the medium-sized continuous firing equipment of transformer equipment every
Sound facility, mainly using modular sound insulation house (cover).Described modular sound insulation house (cover), is typically first by pre-
The sound panel of system forms siding, bottom plate etc., then couples each board member by fastener in device context and install, with reach every
The effect of sound.Sound panel selects alloy sheets, aluminium sheet encapsulation sound-absorbing material to be made mostly at present, and sound-absorbing, soundproof effect are limited, make
Valency is higher, and aluminium sheet is easily corroded and influences the service life.Stainless steel has unique intensity, higher wearability, superior
Antiseptic property and being not easy the excellent characteristic such as get rusty, be also commonly used for sound panel, but simple stainless steel materials sound insulation is made
Effect is unsatisfactory.
General object all has a soundproof effect, but we mean transmission loss (in infinitely great space, sound source with
An infinitely great material is put between measured point) more than 30dB plate just referred to as sound panel.Sound panel is generally high density material
But in the prior art, sound absorption soundproof construction wallboard effect is often bad, is extremely difficult to its effect declared, its
Middle a big chunk is the one side only focused on because of plate in noise control and damping, and have ignored another aspect, therefore, it is necessary to
A kind of noise control damping Acoustic barrier plate, solves the above problems.

In figure：1. 2. acoustic board aperture of wave acoustic board, 3. sound-proof damping felt, 4. hollow 5. hollow layer of double-layer rubber plate
6. 7. hollow glass layer of damping spring group, 8. glass evacuated 9. adhesive-layer of layer.
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Refering to Figure 1, the utility model provides a kind of technical solution：A kind of noise control damping Acoustic barrier plate, belongs to and builds
Build field of material technology, including wave acoustic board 1, acoustic board aperture 2, sound-proof damping felt 3, hollow double-layer rubber plate 4, hollow layer
5th, damping spring group 6, hollow glass layer 7, glass evacuated layer 8, adhesive-layer 9, the wave acoustic board 1 is on the inside of most, thereon
With acoustic board aperture 2, sound-proof damping felt 3 is located between wave acoustic board 1 and hollow 4 inner plating of double-layer rubber plate, hollow double
Layer rubber slab 4 forms a frame structure, and centre has hollow layer 5, has damping spring group 6, hollow double-layer rubber in hollow layer 5
4 lamina rara externa of plate is connected with hollow glass layer 7, and adhesive-layer 9 is attached to the outside of hollow glass layer 7.
Operation principle：The sound absorption soundproof construction wallboard by inner side to outside be respectively wave acoustic board 1, sound-proof damping felt 3,
Hollow double-layer rubber plate 4, hollow glass layer 7, adhesive-layer 9, in use, being glued the sound absorption soundproof construction wallboard by adhesive-layer 9
It is attached on wall, since most inner side is wave acoustic board 1, and have acoustic board aperture 2 thereon, can effectively absorbs sound,
Noise is reduced, sound-proof damping felt 3 is using new super quiet fragrant deadening felt, and using high-purity Fine iron powder as raw material, application is newest
Damping sound insulation technology, can substantially reduce the sound insulation level of plate, pass through the hollow layer 5 being arranged in hollow double-layer rubber plate 4
Interior damping spring group 6, can effectively carry out damping, will shake pass to elastomeric material in hollow double-layer rubber plate 4 into
Row absorbs, and by using hollow glass layer 7, using vacuum sound insulation effect, improves the sound insulation level of plate, simple in structure, manufactures
