Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
- 2 are please referred to Fig.1, the utility model provides technical solution：A kind of wall body structure of civil buildings sound insulation, including dragon
Bone holder 1 and multilayer sound insulating layer 4, the keel bracket 1 include lateral keel plate 11, longitudinal keel plate 2 and interval keel plate 3；
It is mainly used for supporting role so that the sound-insulation wall sound construction.
The lateral keel plate 11 and interval 3 front and rear sides of keel plate are equipped with the baffle 12 of integral structure, apart from institute
It states 12 inside of baffle and is equipped with a partition board 13, mounting groove 14 is formd between the partition board 13 and baffle 12, mounting groove is for fixing
Cement plate forms mounting portion 15 between the mounting groove 14, and mounting portion is for installing multiple longitudinal keel plates, the longitudinal direction
Keel plate 3 is equipped with multiple, is located to equidistant intervals on lateral keel plate 11 and mounting portion 15 that interval keel plate 3 has
It is interior；It is easily installed multilayer sound insulating layer.
The multiple longitudinal keel plate 3 is c-type structure comprising is located at outline border 31 and is located at multiple between outline border 31
The spacing board 32 of equidistant intervals arrangement, forms between the spacing board 32 of the multiple equidistant intervals arrangement for installing
Multiple interval troughs 33 of multilayer sound insulating layer；It is easily installed multilayer sound insulating layer.
The multilayer sound insulating layer 4 from it is rear to preceding be respectively sound-proof damping felt 41, sound-proof material 42 and perforated sound-absorbing plate 43, point
It is not inserted into corresponding interval trough 33.Sound-proof damping felt material is light, ultra-thin, soft, tensile strength is big, black finish；
Sound-proof material is to shake to generate sound in object, and when sound wave transmits in air, cotton has stringy texture, sound wave logical
When crossing cotton by the reflection of countless fibers, be overlapped mutually, collide, acoustic wave energy is converted into thermal energy, and intensity of acoustic wave weakens, and sound disappears
It loses.
Perforated sound-absorbing plate is namely perforated plaster board, is referred to and is run throughPlasterboardThe cylindrical hole of front and back
Eye is formed in group platforms such as the sound-absorbing materials that the back of the body of the gypsum back stickup with gas permeability covers material and can absorb incident acoustic energy.
Sound absorbing mechanism is the hole that material internal has a large amount of small connections, and sound wave can go deep into material internal along these holes, with
Material occurs rubbing action and converts acoustic energy to thermal energy.The sound absorption characteristics of sound-absorbing porous material are to increase sound absorption system with frequency
Number gradually increases.
Above-mentioned multiple sound insulation layer, multiple sound insulation layer only 19.5 millimeters thick, can easily obtain 55+ decibels of sound insulation of wall, wall
Body insulate against sound 50+ decibel when most economical solution, when obtaining 50+ decibels of sound insulation, wall is most thin, without any organic matter row
It puts, safety and environmental protection, a small amount of material obtains high sound insulation effect, green energy conservation.
The baffle 12 that the interval keel plate 3 is equipped with upwardly or downwardly extends respectively to be protruded, on the interval keel plate 3
End and lower end are equipped with the partition board 13 being oppositely arranged.
It is mounted with cement plate 5 respectively between the lateral keel plate 11 and interval keel plate 2 are equipped with mounting groove 14.
Arrange on the perforated sound-absorbing plate 43 it is multiple rows of perforation 431, shape is circle.
It is isodistantly spaced and is intervally arranged between multiple rows of perforation 431.
Based on the above-mentioned technical proposal, the method that the utility model tackles noise is exactly to first have to resolve the leakage sound of window to ask
Topic, will reach every fan window and tightly seal reality, seek to sound insulation and the sealing performance of reinforced door in next step, it is therefore necessary to using sound insulation
The above R values of performance rate three-level are preferred up to the profession fire prevention of 30dB (A) or more, Soft Roll soundproof door or steel fire prevention soundproof door, can
It is spread from door with hindering this sound source, by noise control within doors.Then, sound absorption, the sound insulation value for improving wall, by transverse direction
In the mounting portion that keel plate and the interval keel plate being equipped with are equipped with, it is provided with according to width of wall body and mounting stability multiple vertical
To keel plate, sound-proof damping felt is used from rear to preceding respectively according to the interval between adjacent longitudinal keel plate, sound-proof material and is worn
Then hole abatvoix installs cement plate, to realize on lateral keel plate and in the mounting groove that has of interval keel plate
Sound insulation.
The setting for the baffle and partition board that the utility model is equipped with by lateral keel plate and interval keel plate, by lateral keel
Plate and interval keel plate are divided into mounting groove and mounting portion, are easily installed cement plate and longitudinal keel plate；Multiple longitudinal keel plates
Between setting so that the interval trough that partition board provided therewith is formed is easy to fixed multilayer sound layer and multilayer sound insulation arrangement layer is reasonable,
