Description
Technical field
The utility model is related to wall field, more specifically, it relates to a kind of sound-proof wall body structure.
Background technology
With the rapid development of social economy, the continuous improvement of people's living standard, noise pollution increasingly by
Pay attention to.
In the prior art, keel frame stand is usually first installed in the installation of wall, then installs plasterboard, sound insulation successively
Plate, decorative panel.Generally, everybody selects to be improved the material structure or wall overall structure of sound panel, to increase wall
The soundproof effect of body structure.As patent announcement number be CN201013038Y Chinese patent propose a kind of Lightweight sound insulating wall,
It is formed by three layers of light-weight sound insulating board are arranged in parallel, and rock wool layer is respectively equipped with per between adjacent two layers light-weight sound insulating board.
But in practical applications, keel frame is generally metal material, and the transaudient effect of solid especially metal is more
Good, sound can be propagated along the keel frame of metal material, and the soundproof effect for leading to wall body structure is not ideal enough.
Utility model content
Can be conducted for sound in practice by keel and fastener, wall soundproof effect it is not ideal enough this
Problem, the purpose of this utility model is that a kind of sound-proof wall body structure is proposed, by subtracting in keel and the setting of fastener junction
The kinetic energy that vibration absorber vibrates by the conduct vibrations on keel and fastener to vibration absorber, is converted into thermal energy, disappeared by vibrating device
Consumption vibration, reaches sound insulation, sound-absorbing effect, concrete scheme is as follows：
A kind of sound-proof wall body structure, including wall, Acoustic barrier plate and the dragon between the wall, Acoustic barrier plate
Bone.Fastening through-hole is offered on the keel, is provided with fastener in the fastening through-hole, the keel and the wall it
Between, connected by the fastener between the keel and the Acoustic barrier plate.The sound-proof wall body structure further includes one
For slowing down the vibration absorber of keel and/or fastener vibration.
The vibration absorber includes fixed part and shock absorption bar, and the fixed part is flaky to be attached to the fastener
On outer wall, the junction of the keel and the fastener is inserted into the free end of the fixed part.The shock absorption bar is integrally in length
Strip simultaneously has elasticity, and one end of the shock absorption bar is fixed with the fixed part, and the other end is set far from the fastener, described
The center of gravity of shock absorption bar is located at the one end of the shock absorption bar far from the fastener.
Through the above technical solutions, when sound transmission is to keel and fastener, the vibration of keel and fastener can be driven,
The vibration of keel and fastener causes the vibration of fixed part, and then cause the vibration of shock absorption bar.Since shock absorption bar is elongated, tool
It is flexible, and center of gravity is towards its free end, therefore the end of shock absorption bar free end can high vibration.The shock absorption bar of high vibration will
Kinetic energy converts thermal energy, so as to dissipate the vibration of sound, so as to reach sound-absorbing, soundproof effect.Dragon is inserted into the free end of fixed part
The junction of bone and fastener so that the connection of keel and fastener is closer, the connection between keel and wall, Acoustic barrier plate
More securely.
Further, the one end of the shock absorption bar far from the fastener is set in spherical or plate.
Further, the fixed part and shock absorption bar are integrally formed setting for stainless steel material.
Through the above technical solutions, the transaudient effect of stainless steel material is good, the elasticity of the stainless rigidity shock absorption bar of strip is good,
Therefore fastener vibration can drive the high vibration of fixed part and shock absorption bar easily, and rolling can be generated when shock absorption bar vibrates
It is dynamic, acoustical vibration is passed at vibration absorber and dribbled, reaches sound-absorbing, soundproof effect.
Further, the shock absorption bar has multiple, and multiple shock absorption bars are distributed in the fixed body far from the fastening
The side of part, the vibration frequency of multiple shock absorption bars are not all the same.
Through the above technical solutions, multiple shock absorption bars can more shift the vibration of fastener, and vibration frequency is not
It is all identical, it is vibrated between multiple shock absorption bars, the frequency of vibration has complementation, so as to weaken the vibration between shock absorption bar,
Sound reduces.
Further, the fastener is tapping screw.
Through the above technical solutions, tapping screw can be from drilling, the screw thread that tapping coordinates with it has high locking energy
Power so that connected between wall and keel, between keel and Acoustic barrier plate more firm.
Further, it is provided with elastic washer between the head of the tapping screw and the keel.
Through the above technical solutions, elastic washer can slow down the vibration between the head of tapping screw and keel, so as to
Reduce the vibration ability that sound transmits therebetween, sound insulation, sound-absorbing.Meanwhile elastic washer increases bolt and keel frame
Between contact area, reduce keel frame suffered by pressure, protection keel frame preserve from, and play sealing function, prevent
Bolt looseness.
Further, the elastic washer is corrugated gasket.
Further, the fastener outer wall is arranged with sound insulating seal pipe.
Through the above technical solutions, sound insulating seal pipe can absorb partial sound, shaking between fastener and keel is obstructed
Dynamic to propagate, sound is not easy to propagate between fastener and keel, so as to achieve the purpose that sound-absorbing, sound insulation.
Further, the sound insulating seal pipe is butyl rubber seal pipe.
Through the above technical solutions, butyl rubber has good shock-absorbing performance, when sound is transmitted to keel frame and tight
When on firmware, the Oscillation Amplitude of the two can be reduced, and obstruct Vibration propagation between the two, reduce sound；Meanwhile butyl rubber
Glue is long with excellent properties, the service life such as heat-resisting, resistance to oxidation, ageing-resistant.
Compared with prior art, the beneficial effects of the utility model are as follows：
（1）By setting vibration absorber in keel and fastener junction, by the conduct vibrations on keel and fastener extremely
The kinetic energy of vibration is converted into thermal energy by vibration absorber, vibration absorber, consumes vibrational energy, reaches sound insulation, sound-absorbing effect, improves work
Make living environment；
（2）By setting sound insulating seal pipe and being set between keel and fastener, obstruct between keel and fastener
Vibration propagation reaches sound-absorbing, soundproof effect.
