Description
Technical field
The utility model belongs to high-speed railway noise reduction technology field, more particularly to a kind of foamed aluminium sound-screen used for high-speed railway
Barrier sound absorption plate.
Background technology
The high-speed railway of China's construction brings to overturn and sexually revises to the travel modal of people, but is giving people
While offer convenience, noise pollution caused by high-speed railway operation can not be ignored.
For the resident for living in line of high-speed railway, when high ferro train passes through, the huge noise of generation is to edge
The normal life of line resident brings serious influence, it is therefore desirable to installs sound barrier in high-speed railway both sides to carry out noise reduction.
At present, the sound barrier that high ferro circuit uses does not have sqouynd absorption lowering noise effect, main reason is that the sound absorption of sound barrier
The noise frequency of frequency and high-speed railway is completely not suitable with, this sound barrier be by Pierced Aluminum Plank and 140mm thickness cavity or
Filling mineral wool cavity is made, its noise frequency that can be absorbed is below 100Hz, and caused by high ferro train high-speed cruising
Noise frequency is 1000Hz~2000Hz.Therefore, existing sound barrier does not have sqouynd absorption lowering noise effect.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of foamed aluminium sound barrier sound absorption used for high-speed railway and inserts
Plate, the noise frequency that can be absorbed are 500Hz~2000Hz, the noise frequency that its frequency that absorbs sound can preferably with high-speed railway
It is adapted, noise reduction can be effectively improved, significantly reduce influence of the noise to subjective reflection.
To achieve these goals, the utility model adopts the following technical solution：A kind of foamed aluminium sound-screen used for high-speed railway
Barrier sound absorption plate, including Foamed aluminum sound absorbing plate, setback plate and steel plate, the Foamed aluminum sound absorbing plate are met to train, the steel plate position
On the outside of Foamed aluminum sound absorbing plate, the setback plate is clipped between Foamed aluminum sound absorbing plate and steel plate, is pacified in the outer circumferential side of setback plate
Equipped with outer framework；Continuous change spacing cavity zone is formed between the setback plate and Foamed aluminum sound absorbing plate.
The thickness of the Foamed aluminum sound absorbing plate is 10mm~15mm.
The Foamed aluminum sound absorbing plate uses punched hole noise absorption harden structure, and punching rate is 2%~5%.
The Foamed aluminum sound absorbing plate surface is without coating or with zinc coat or with nickel coating.
The thickness of the setback plate is 1mm~2mm.
The continuous maximum spacing for becoming spacing cavity zone is 20mm~30mm.
The setback plate is made of Zinc-coated steel-plated punch.
The setback plate is mutually be bonded by silicone adhesive between Foamed aluminum sound absorbing plate and steel plate.
Steel plate and the outer framework surface is respectively provided with zinc coat.
The beneficial effects of the utility model：
Compared with prior art, the noise frequency that can be absorbed is 500Hz~2000Hz to the utility model, its frequency that absorbs sound
Noise frequency that can be preferably with high-speed railway is adapted, and can effectively improve noise reduction, and significantly reduces noise to along the line
The influence of resident.
Brief description of the drawings
Fig. 1 is the sound barrier schematic diagram for the foamed aluminium sound barrier sound absorption plate for employing the utility model；
Fig. 2 is A-A sectional views in Fig. 1；
In figure, 1-Foamed aluminum sound absorbing plate, 2-setback plate, 3-steel plate, 4-outer framework, 5-continuously become spacing cavity zone,
6-sound barrier installs column, 7-foamed aluminium sound barrier sound absorption plate.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of foamed aluminium sound barrier sound absorption plate used for high-speed railway, including Foamed aluminum sound absorbing plate 1, setback
Plate 2 and steel plate 3, the Foamed aluminum sound absorbing plate 1 are met to train, and the steel plate 3 is located at the outside of Foamed aluminum sound absorbing plate 1, the setback
Plate 2 is clipped between Foamed aluminum sound absorbing plate 1 and steel plate 3, and outer framework 4 is provided with the outer circumferential side of setback plate 2；In the setback plate
Continuous change spacing cavity zone 5 is formed between 2 and Foamed aluminum sound absorbing plate 1.
The thickness of the Foamed aluminum sound absorbing plate 1 is 10mm~15mm.
The Foamed aluminum sound absorbing plate 1 uses punched hole noise absorption harden structure, and punching rate is 2%~5%.
1 surface of Foamed aluminum sound absorbing plate is without coating or with zinc coat or with nickel coating.
The thickness of the setback plate 2 is 1mm~2mm.
The continuous maximum spacing for becoming spacing cavity zone 5 is 20mm~30mm.
The setback plate 2 is made of Zinc-coated steel-plated punch.
The setback plate 2 is mutually be bonded by silicone adhesive between Foamed aluminum sound absorbing plate 1 and steel plate 3.
4 surface of steel plate 3 and outer framework is respectively provided with zinc coat.
In the present embodiment, the size of monolithic foamed aluminium sound barrier sound absorption plate is 1960mm × 400mm, in short transverse
On, some blocks of foamed aluminium sound barrier sound absorption plates 7 are inserted between adjacent two sound barrier installation columns 6, when sound barrier uses
After the foamed aluminium sound barrier sound absorption plate 7 of the utility model, noise during high ferro train operation will directly be absorbed sound by foamed aluminium
Plate 1 absorbs, being capable of absorption frequency due to that can form continuous change spacing cavity zone 5 between setback plate 2 and Foamed aluminum sound absorbing plate 1
For the noise of 500Hz~2000Hz, the noise frequency that its frequency that absorbs sound can be preferably with high-speed railway is adapted.It is but existing
Sound barrier cannot absorb high ferro noise, can not reach noise reduction, and the sound barrier for employing the utility model then can be bright
It is aobvious to absorb high ferro noise, and noise reduction reaches more than 20dB, therefore significantly reduce influence of the noise to subjective reflection.
Scheme in embodiment and the scope of patent protection for being not used to limitation the utility model, it is all without departing from the utility model
Carried out by equivalence enforcement or change, be both contained in the scope of the claims of this case.
