Description
[technical field]
The invention belongs to frame for movement technical field, be a kind of sound-absorbing wall in more detail.
[background technology]
Along with acoustics in space and decorative effect are required by developing rapidly of China's Building technology with people
Day by day improve, have in a large number the sound-absorbing material of different sound absorption qualities and multiple have different fabrication and installation knot
The abatvoix of structure and mode has obtained increasing application.
But the installation of abatvoix is comparatively laborious, it is often necessary to use conventional attachments to be attached, also simultaneously
Need to use multiple installation tool, complex operation, waste time and energy；Furthermore, existing sound-absorbing structure sound-absorbing is imitated
Fruit is the most bad, in addition it is also necessary to constantly carry out the improvement in structure.
[summary of the invention]
It is an object of the invention to provide a kind of sound-absorbing wall, to solve the installation behaviour proposed in above-mentioned background technology
Make loaded down with trivial details, the technical problem wasted time and energy.
For achieving the above object, the present invention provides following technical scheme:
A kind of sound-absorbing wall, including fix with foundation wall be connected fixing bolt, card bone, end fastener,
Middle part fastener, horizontal frame, vertical framework and framework plug connector；Described card bone is solid with described fixing bolt
Fixed connection, described end fastener and described middle part fastener are all connected together, described in two with described card bone
It is assembled into rectangular frame by four described framework plug connectors between horizontal frame and two described vertical frameworks,
Rectangular frame described at least three from top to bottom pass sequentially through described end fastener and described middle part fastener with
Described card bone is connected together, and described rectangular frame is used for installing abatvoix.
Further, described card bone is provided with at least four to the first draw-in groove, the one of each described end fastener
One end of end and each described middle part fastener is equipped with a pair can be with on described card bone described the first of setting
Suitable the first grab being connected together of draw-in groove, the other end of each described end fastener is equipped with a pair
Second grab, the other end of each described middle part fastener is equipped with two to described second grab, Mei Gesuo
State and on horizontal frame, be equipped with the second draw-in groove that can suitable with described second grab be connected together.
Further, on described horizontal frame or described vertical framework is provided with holding for support abatvoix
Supporting plate, described supporting plate is positioned at the inner side of described rectangular frame.
Further, described vertical framework is made up of square steel, and described horizontal frame is by the side of square steel
Arrange what described second draw-in groove was constituted on face.
Further, one end of described framework plug connector can be plugged in the square steel of described vertical framework, institute
The other end stating framework plug connector can be plugged in the square steel of described horizontal frame, be used for connecting described vertically
Framework and described horizontal frame.
Further, offer multiple through hole at the medium position of described card bone, all wear in each described through hole
If described fixing bolt, it is bolted on foundation wall by described fixing.
Further, described abatvoix includes sound-absorbing framework and the first suction being arranged in described sound-absorbing framework
Sound-absorbing layer and the second sound absorbing layer, described first sound absorbing layer is arranged on the outside of described second sound absorbing layer；Described first
Sound absorbing layer and described second sound absorbing layer are all by many vertical placements by the trapezoidal bar of multiple horizontal positioned
Metal bar is formed by connecting, and the upper bottom surface of all of trapezoidal bar all facing away from described foundation wall, and described
Splayed is formed between the central plane of two trapezoidal bars of arbitrary neighborhood in one sound absorbing layer and in described second sound absorbing layer
Opening, shown splayed opening ecto-entad bore successively decreases.
Further, the central plane of described trapezoidal bar is pleated structure.
Further, described abatvoix includes multiple described first sound absorbing layer and multiple described second sound absorbing layer,
Described first sound absorbing layer and described second sound absorbing layer ecto-entad intersecting are arranged, and the most adjacent described the
Gap is left between one sound absorbing layer and described second sound absorbing layer.
It should be noted that splayed opening ecto-entad successively decreases, illustrate that the mouth towards outside is big, strengthen
The contact area of abatvoix and noise, inwardly open is gradually reduced, noise can constantly with the waist of trapezoidal bar
Face is collided, and each collision all makes sound attenuating, has reached the effect of noise reduction, and ecto-entad is provided with
Multiple first sound absorbing layers and the second sound absorbing layer, therefore, it is possible to reach perfect absorbing sound and lowering noise effect.
Further, the size of all trapezoidal bar of described first sound absorbing layer is the most in the same size, and described second inhales
The all trapezoidal bar of sound-absorbing layer is smaller in size than the trapezoidal bar size of described first sound absorbing layer, described second sound absorbing layer
Trapezoidal bar be the trapezoidal bar of described first sound absorbing layer equal proportion scaling after obtain, and described second sound absorbing layer
All trapezoidal bar the most in the same size.
So that absorbing sound and lowering noise effect is more preferable, it is preferable that described metal bar uses metallic copper material to make,
Described trapezoidal strip adoption polyurethane material is made.Metallic copper transmission sound wave more rapid, by noise rapidly to
Internal layer transmits, and polyurethane material have loose structure can sound-absorbing well, in sum, use above-mentioned
The abatvoix that material is made has quick and double effects thoroughly of eliminating the noise.
The invention has the beneficial effects as follows: all of attachment structure (in addition to fixing bolt and abatvoix) is the most logical
Cross the mode being connected together to connect, simple to operate, it is not necessary to additionally preparation tool, save the time of installation,
And position more accurate.
