Abstract
The utility model discloses a damping sound insulation screen, aiming to provide the damping sound insulation screen which has the strong anti-wind load capability, can prevent a barrier from dithering and increase the sound insulation capability. The damping sound insulation screen comprises a quadrilateral frame with grooves, a sound absorbing board, a protection slab with sound transmission holes, a protection board, a damping board. Wherein the sound absorbing board is inserted into the grooves of the frame, the protection slab with the sound transmission holes is installed at the inside of the sound absorbing board, the damping board is installed at the outside of the sound absorbing board, the protection board is installed at the outside of the damping board, the damping board is a fireproofing board. In the utility model, the damping board is installed at the outside of the sound insulation screen, the protection slab with the sound transmission holes is installed at the inside thereof, the sound insulation barrier which is formed by the sound insulation screen of the utility model has the strong anti-wind load capability, prevents the barrier from dithering, and increase the sound insulation capability of the barrier. In addition, because the anti-wind load capability is increased, the service life of the barrier is prolonged.
Description
Technical field
The utility model relates to the noise processed field, in particular, relates to a kind of damping acoustic screen.
Background technology
Noise is to the interference of surrounding environment, and able-bodied threat more and more is familiar with by people to human body, and noise abatement more and more is subject to people's attention as the part of environmental improvement.At the top of building some equipment are installed, as cooling tower etc., produce very big noise in the running, conventional acoustic screen adopts steel sheet and acoustical board to form, because the increase of depth of building, the noise barrier that adopts conventional acoustic screen plate to be assembled into is lower owing to intensity, does not have due wind resistance load-carrying ability, thereby the single thin layer steel plate is shaken easily and is formed certain noise, has reduced the ability of acoustic screen processing noise pollution.And when wind-force was big, noise barrier was destroyed easily.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of wind resistance load-carrying ability strong, can stop the barrier shake, strengthening the damping acoustic screen of sound-insulation capability.
The utility model is achieved through the following technical solutions:
A kind of damping acoustic screen, it is characterized in that, comprise quadrilateral frame, the acoustical board that has groove, the protection slab that has sound transmission aperture, protected apron, damping sheet, described acoustical board inserts in the groove of framework, installed inside at acoustical board has the protection slab that has sound transmission aperture, the outside at acoustical board is equipped with damping sheet, and the outside of described damping sheet is equipped with protected apron, and described damping sheet is a PLASTIC LAMINATED.
Because be installed in the open, described acoustical board adopts the not material of water funk Qin, as polyurethane foam etc.
Described damping sheet adopts the two sides to scribble the fiberboard of fire prevention enamelled coating.
The thickness of described damping sheet is 4-8mm.
The thickness of described acoustical board is 80-120mm.
It is the perforation galvanized sheet of 0.6-0.8mm that the described protection slab that has sound transmission aperture adopts thickness.
It is the steel plate of 1-2mm that described protected apron adopts thickness.
The steel plate compacting that the described quadrilateral frame employing thickness that has groove is 1-1.5mm forms.
The utlity model has following technique effect:
The acoustic screen of the present utility model outside is equipped with damping sheet, and installed inside has protection slab with holes, and the noise barrier wind resistance load-carrying ability of being made up of acoustic screen of the present utility model is strong, has stoped the shake of barrier, has strengthened the sound-insulation capability of barrier.And, since the reinforcement of wind resistance load-carrying ability, the application life of having improved barrier.
Description of drawings
Fig. 1 is the schematic diagram of the utility model damping acoustic screen.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the schematic diagram of the utility model damping acoustic screen, comprise quadrilateral frame 1, the acoustical board 3 that has groove, the protection slab 5 that has sound transmission aperture, protected apron 4, damping sheet 2, acoustical board 3 inserts in the groove of framework 1, installed inside at acoustical board 3 has the protection slab 5 that has sound transmission aperture, in the outside of acoustical board 3 damping sheet 2 is installed, the outside of described damping sheet 2 is equipped with protected apron 4, and described damping sheet is a PLASTIC LAMINATED.
Wherein, acoustical board 3 is a polyurethane foam, and the thickness of acoustical board is 80-129mm.Described damping sheet adopts the two sides to scribble the fiberboard of fire prevention enamelled coating.Described damping sheet adopts the two sides to scribble the fiberboard of fire prevention enamelled coating.The thickness of damping sheet is 4-8mm.The thickness of described acoustical board is 80-120mm.It is the perforation galvanized sheet of 0.6-0.8mm that the described protection slab that has sound transmission aperture adopts thickness.It is the steel plate of 1-2mm that described protected apron adopts thickness.The steel plate compacting that the described quadrilateral frame employing thickness that has groove is 1-1.5mm forms.
Every of damping acoustic screen finished product plate of the present utility model is 1 meter * 2 meters, plate is fixed in the framework of H shaped steel, is installed in top of building, becomes noise barrier, acoustical board absorbs the noise that top of building equipment such as cooling tower sends, and reaches the purpose of environment purification.Owing to adopt PLASTIC LAMINATED as damping sheet, strengthened the sound-insulation capability of barrier, and stoped the barrier shake.Sound wave enters sound absorption material by the sound transmission aperture on the protection slab, is absorbed, and avoids reflection.
Although relate to a kind of damping acoustic screen and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
