Abstract
The present invention relates to a kind of full aluminium perforated acoustic board, it includes steel column, and aluminium perforated acoustic board is provided between the steel column, and they are compressed by Z-type spring fastener and the steel column and connected；The aluminium perforated acoustic board includes aluminium perforated panel, centrifugally glass-wool and zinc-plated steel backing plate, and it is embedded concave convex groove structure that the framework that the aluminium perforated panel and zinc-plated steel backing plate form, which is vertically connected with part,.The present invention is rational in infrastructure, intensity is big, saves material, in light weight, acoustically effective is good.
Description
Technical field
The present invention relates to different kinds of roads and track traffic and high ferro denoising device, and in particular to a kind of absorbent lined barrier board.
Background technology
With the progress of society and the development in city, people's living standard constantly improves, urban transportation have become with
The problem of we are most closely related.Substantial amounts of expressway is built up, and urban light rail and high-speed railway are open to traffic, to our trip
Bring great convenience, but the resident stayed in simultaneously near these expressways, light rail and high ferro suffer from traffic noise
Influence.In order to improve civic living environment, relevant department is mounted with various in both sides of the road and light rail, high ferro etc. around along the line
Absorbent lined barrier.
Present absorbent lined barrier board typically sets panel and backboard, and panel and backboard use slab construction, opened on panel
There is sound-absorbing hole, skeleton is set between panel, backboard, sound-absorbing porous material is set between skeleton.However, with panel, backboard
The development trend of sheet metal thickness more and more thinner, the intensity of absorbent lined barrier board also increasingly cause the common concern of designer.Solve
The method of this problem, usually increase the density and intensity of skeleton, but this can significantly increase the dosage of material, and barrier
The weight of plate can also increase much therewith.
The content of the invention
Goal of the invention：It is an object of the invention to overcome the shortcomings of above-mentioned prior art, there is provided a kind of rational in infrastructure, intensity
Greatly, material, in light weight, the good Felt of acoustically effective are saved.
Technical scheme：In order to solve the above-mentioned technical problem, full aluminium perforated acoustic board of the present invention, it stands including steel
Post, aluminium perforated acoustic board is provided between the steel column, they are compressed by Z-type spring fastener and the steel column and connected；Institute
Stating aluminium perforated acoustic board includes aluminium perforated panel, centrifugally glass-wool and zinc-plated steel backing plate, the aluminium perforated panel and zinc-plated steel back
It is embedded concave convex groove structure that the framework of plate composition, which is vertically connected with part, and this structure enhances the sealing effect between Felt and plate
Fruit and bonding strength.
The punching rate of the aluminium perforated panel is more than 25%, enhances the sound absorption acoustical behavior of panel, is more beneficial for sound wave
Absorption, panel uses the stamping forming structure of micropunch.
The aluminium perforated panel and zinc-plated steel backing plate are that clamping forms.
The zinc-plated steel backing plate back carries V-shaped, the V-shaped design at backboard back, strengthens the same of Felt intensity
When, because intralamellar part has cavity, also the absorption to low-frequency sound is more favourable.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：This full aluminium perforated acoustic board is rational in infrastructure,
Intensity is big, saves material, in light weight, acoustically effective is good.
Brief description of the drawings
] Fig. 1 be the present invention structural representation；
Fig. 2 is the side view of the present invention；
Fig. 3 is the structural representation of panel and backboard in the present invention.
Wherein：
1st, steel column；2nd, aluminium perforated acoustic board；3rd, Z-type spring fastener；4th, aluminium perforated panel；5th, centrifugally glass-wool；6th, galvanized steel
Backboard；7th, framework；8th, embedded concave convex groove structure.
Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2 and Figure 3, full aluminium perforated acoustic board of the present invention, it includes steel column 1, stood in the steel
Aluminium perforated acoustic board 2 is provided between post 1, they are compressed by Z-type spring fastener 3 and the steel column 1 and connected；The aluminium perforation
Acoustic board 2 includes aluminium perforated panel 4, centrifugally glass-wool 5 and zinc-plated steel backing plate 6, the aluminium perforated panel 4 and zinc-plated steel backing plate 6
It is embedded concave convex groove structure 8 that the framework 7 of composition, which is vertically connected with part,；The punching rate of the aluminium perforated panel 4 is more than 25%；It is described
Aluminium perforated panel 4 and zinc-plated steel backing plate 6 are that clamping forms；The back of zinc-plated steel backing plate 6 carries V-shaped.Structure of the present invention is closed
Reason, intensity are big, save material, in light weight, acoustically effective is good.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
