Description
Technical field
The present invention relates to a kind of sound insulating structure, the anechoic room pipe especially effectively to be insulated against sound in the cable pipeline of anechoic room
Line sound insulating structure.
Background technology
Anechoic room includes whole elimination room and semianechoic room, and anechoic room is not only a special experimental laboratory of acoustical testing, and
And be the important component of test system, actually it is also one of acoustic test equipment, its direct shadow of acoustical behavior index
Ring the precision of test.The key technology and the key technical indexes of anechoic room are high oise insulation factors, make to reach low noise ring in anechoic room
Border, background noise value is lower in anechoic room, and test effect is better.
In anechoic room construction project, how the pipeline of the installation controlling cable to being reserved in anechoic room sound insulating structure is carried out
Effectively sound insulation, it is most important to the defening effect of whole engineering.With the variation of test sample, the sound level of test requires more next
It is lower.In general, if the ambient noise of anechoic room is less than test sample sound level 10dB (A) below, to the shadow of test result
Ring just it is little, if the ambient noise of anechoic room less than test sample sound level 15dB (A) below, to test result substantially without
Influence.Because the noise of anechoic room surrounding environment is inevitable, if anechoic room requirement reaches 60dB (A) oise insulation factor,
In the case where the oise insulation factor of anechoic room building enclosure meets to require, as long as gap hole reaches million parts of building enclosure area
One of cannot reach sound insulation standard.It is complicated and pipeline is intraoral has control, power cable to pass through, consider again from now on
Pipeline mouth sound insulating structure is removed and installed when anechoic room test equipment is exchanged and insulated against sound without prejudice to it.
《Anechoic room and semianechoic room technical specification》8 constructions are installed with the wedge body of quality control 8.5 and acoustic construction
8.5. when 13 pairs of walls carry out through hole construction, Light Wall must carry out Seal treatment to wall section.Through hard pipeline
There must not be any Hard link with wall, its gap is filled with sound-absorbing material and closed.Need to eliminate the noise if necessary or sound lock is handled.
At present, the sound insulation of anechoic room pipeline is to restrict the principal element of anechoic room background noise reduction.At present or use
Flexible sound absorption and insulation material closure, defening effect is all undesirable, constrains the raising of anechoic room oise insulation factor.
The content of the invention
The present invention provides a kind of pipeline sound insulating structure of anechoic room, can effectively obstruct outside noise toward indoor propagation,
Oise insulation factor is far above the pipeline sound insulating method of current anechoic room, and with detachable installation function again, sets simple.
The technical solution adopted in the present invention：A kind of anechoic room pipeline sound insulating structure, by pipeline poling, poling sealing, every
Shake component, sound-absorbing material, flexible sound-insulating felt, air-conditioning earth rubber, Powerful hoop composition.Two pipeline polings are passed through in anechoic room respectively
Sound insulating structure, outer sound insulating structure, cable enter in anechoic room through pipeline poling；Seam is left between pipeline poling and sound insulating structure
Gap, partiting polarization component are arranged between sound insulating structure and pipeline poling, and poling, which seals, is arranged on pipeline poling outer end, in poling sealing
On the outside of pipeline poling with there is screw thread cooperation side；Flexible sound-insulating felt is vertically mounted on poling sealing inside and pipeline poling top
Between；It is outer that Powerful hoop is arranged on poling sealing, sets flexible sound-insulating felt between Powerful hoop and cable, and the gap between cable is used
Air-conditioning earth rubber is tightly crammed, and cable is concentrated constraint to form circle by Powerful hoop；Set between Powerful hoop and cable it is flexible every
Sound felt can prevent damage of the hooping structure to cable surface.Gap installation sound absorption material between in the middle part of cable and pipeline poling
Material, the gap between cable and the end of pipeline poling two is tightly crammed with air-conditioning earth rubber.It can pass through when acoustic wave segment between cable
Gap, the gap between cable and pipeline poling is when entering in pipeline poling, sound-absorbing material can effectively absorb, decay sound
Ripple, reach the purpose that barrier noise passes through.Cavity of the two described pipeline polings between interior sound insulating structure, outer sound insulating structure
It is relative to dock, 5mm spacing is left between two pipeline polings.Contact forms overhead speaker between pipeline poling can be prevented, passes on
Vibration noise.
The integrated type foaming silica gel component that described partiting polarization component is made up of inner thick outer thin differential of the arc annulus and cylindrical shape, pipe
Match somebody with somebody between the external diameter of line poling and columnar internal diameter, between the perforate of columnar external diameter and anechoic room sound insulating structure for gap
Close, columnar height is the thickness of anechoic room sound insulating structure.The transmission of vibration can be obstructed using foamed silica gel product, is prevented
Form overhead speaker.Meanwhile the good weatherability of foamed silica gel.Foamed silica gel differential of the arc cylinder is close to sound insulating structure, can effectively prevent
Sound wave is transmitted by the gap between differential of the arc plate and sound insulating structure.Described pipeline poling is set the circle of external thread structure by one end
Bobbin is made, and the integral type poling sealing formed is sealed in the sealing of described poling by cylindrical shape female thread structure, top circular ring type；
The external thread structure of pipeline poling and the female thread structure of poling sealing coordinate.Ten strokes are cut open in the middle part of described flexible sound-insulating felt
Mouthful, cable passes through the middle part designated port of flexible sound-insulating felt.The elasticity of flexible sound-insulating felt does not damage cable, is also beneficial to pass in and out cable
Mouth is protected.
Controlling cable is arranged apart with electric power cable, using different pipeline polings, to prevent the magnetic line of force of electric power cable
Influence to controlling cable output signal.
Meet to require the beneficial effects of the invention are as follows the defening effect of anechoic room pipeline sound insulating structure, cable can when need to repair
To dismantle, install without prejudice to sound insulation.
