The sound absorption outer surface parcel sound absorption cotton felt, internal filling high-performance sound absorption cotton, the sound absorption fills in one end with sound absorption gag
Plate, the sound absorption gag plate external diameter is provided with sound absorption flange, and the sound absorption flange matches with flange and corresponding screwed hole is provided with through hole,
The built-in pipe other end equipped with sound insulation plug, the rounded tubulose of the sound insulation plug, the sound insulation footpath and pre-buried bore phase beyond the Great Wall
Match somebody with somebody, the sound insulation outer surface parcel sound absorption cotton felt, internal filling high-performance sound absorption cotton, the sound insulation plug end is provided with sound insulation plug
Cover plate, the sound insulation gag plate external diameter is more than built-in pipe external diameter.
The screwed hole annular is distributed on flange.
Handle is housed on the sound absorption gag plate and sound insulation gag plate.
Through hole is evenly equipped with the sound absorption gag plate.
The sound absorption plug and the plug that insulates against sound are made with perforated plate.
A kind of installation method of sound insulating structure through walls, its step is as follows：
A) first built-in pipe is fixed in the hole of body of wall with structure glue, it is ensured that install closely knit, wall hole and built-in pipe it
Between there is no space；
B) after the completion of built-in pipe is fixed, sound insulation plug is directly filled in into built-in pipe from outer wall；
C) finally sound absorption is filled in from wall inner side and fills in built-in pipe, the through hole that blending bolt will absorb sound on gag plate is fixed on
On the flange of built-in pipe.
Beneficial effect
It is an advantage of the current invention that the filling of internal high-performance sound absorption cotton ensure that filling is closely knit in place, in not existing
Empty phenomenon, the sound absorption cotton felt of perforated plate outside parcel causes sealing-plug and sound insulation to fill in, is between sealing-plug sound insulation plug and built-in pipe
It is flexible coupling, it is to avoid the structural vibration noise that Hard link brings.Ensure that when threading is not needed or equipment is accessed, the structure
Installation ensure that the performance of internal anechoic room is unaffected.
