Abstract
The invention relates to a semitransparent aluminum hole-punched acoustic board which comprises a steel column. The upper portion of the steel column is provided with a transparent acoustic board, the lower portion of the steel column is provided with an aluminum hole-punched plate, and the transparent acoustic board and the aluminum hole-punched plate are in pressed connection with the steel column through Z-shaped spring fasteners. The aluminum hole-punched plate comprises an aluminum hole-punched panel, centrifugal glass wool and a galvanized steel back plate, wherein an upper connecting part and a lower connecting part of a frame composed of the aluminum hole-punched panel and the galvanized steel back plate are of an embedded type concave-convex groove structure. The semitransparent aluminum hole-punched acoustic board is reasonable in structure and high in strength, saves materials, and is light in weight and good in sound absorption effect.
Description
Technical field
The present invention relates to different kinds of roads and track traffic and high ferro denoising device, be specifically related to a kind of absorbent lined barrier board.
Background technology
Along with the progress of society and the development in city, people's living standard constantly improves, and urban traffic has become the most closely-related problem with us.Building up of a large amount of expressways, being open to traffic of urban light rail and high-speed railway brings great convenience for our trip, but stays in simultaneously the impact that near the resident of these expressways, light rail and high ferro is standing traffic noise.In order to improve the civic dwelling environment, relevant department in the road both sides and light rail, high ferro etc. various absorbent lined barriers have been installed around along the line.
Present absorbent lined barrier board operated by rotary motion panel and backboard, panel and backboard all adopt slabbed construction, have the sound absorption hole on the panel, between panel, the backboard skeleton are set, and porous absorption material is set between skeleton.Yet along with panel, development trend that the backboard sheet metal thickness is more and more thinner, the intensity of absorbent lined barrier board also more and more causes designer's common concern.Solution to this problem generally be density and the intensity that increases skeleton, but this can increase the consumption of material significantly, and the weight of shield plates also can increase much thereupon.
Summary of the invention
Goal of the invention: the object of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of rational in infrastructure, intensity is large, saves material, and is lightweight, the Felt that acoustically effective is good.
Technical scheme: in order to solve the problems of the technologies described above, translucent aluminium perforated acoustic board of the present invention, it comprises steel post, is transparent sound barrier on this steel post top, and the bottom is the aluminium perforated plate, and they are connected with described steel post compression by the Z-type spring fastener; Described aluminium perforated plate comprises aluminium perforated panel, centrifugally glass-wool and galvanized steel backboard, described aluminium perforated panel and the framework that forms with the galvanized steel backboard up and down coupling part are embedded tongue and groove structures, this structural reinforcing sealing effectiveness and the bonding strength between Felt and the plate.
The perforated percentage of described aluminium perforated panel has strengthened the sound absorption acoustical behavior of panel greater than 25%, more is conducive to the absorption of sound wave, and panel adopts the stamping forming structure of micropunch.
Described aluminium perforated panel and galvanized steel backboard are that clamping forms.
Described galvanized steel backboard back is with the V font, and the V font at backboard back designs, and is when strengthening Felt intensity, because there is cavity in intralamellar part, also more favourable to the absorption of low-frequency sound.
Described transparent sound barrier is transparent safe doubling glass or transparent PC plate, and its thickness is 10mm.
There are a lot of apertures on the surface of this Felt, after sound enters aperture, just can in the inwall of structure, carelessly reflect, until the energy of most sound wave has all consumed, become heat energy, reached the effect of sound insulation, the stronger absorption acoustic energy of this Felt utilization, the material of reducing noise performance, sound absorption material is divided into by sound absorbing mechanism: 1. by make the porous material of acoustic attenuation to inner many tiny unlimited ducts from the surface, to absorb the medium-high frequency sound wave as main, the centrifugally glass-wool of fibrous aggregate structure inorfil and loose structure is arranged; 2. the membranaceous material of flexible material that absorbs sound by resonant interaction, or board-like material and perforated plate (punching and making on various board-like materials or the metal sheet absorbs intermediate frequency), above Material cladding uses, can enlarge the sound absorption scope, improve sound absorption coefficient, the control noise, porous material is except absorbing air sound, can also weaken solid-borne sound and the caused vibration of empty chamber gas sound, in addition, this product is light and handy, is convenient to install and transportation.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: this translucent aluminium perforated acoustic board is rational in infrastructure, intensity is large, saves material, lightweight, acoustically effective is good.

1, steel post; 2, transparent sound barrier; 3, aluminium perforated plate; 4, Z-type spring fastener; 5, aluminium perforated panel; 6, centrifugally glass-wool; 7, galvanized steel backboard; 8, framework; 9, embedded tongue and groove structure
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Such as Fig. 1, Fig. 2 and shown in Figure 3, translucent aluminium perforated acoustic board of the present invention, it comprises steel post 1, is transparent sound barrier 2 on this steel post 1 top, and the bottom is aluminium perforated plate 3, and they compress with described steel post 1 by Z-type spring fastener 4 and are connected; Described aluminium perforated plate 3 comprises aluminium perforated panel 5, centrifugally glass-wool 6 and galvanized steel backboard 7, described aluminium perforated panel 5 and the framework that forms with galvanized steel backboard 7 about in the of 8 the coupling part be embedded tongue and groove structure 9; The perforated percentage of described aluminium perforated panel 5 is greater than 25%; Described aluminium perforated panel 5 and galvanized steel backboard 7 are that clamping forms; Described galvanized steel backboard 7 backs are with the V font; Described transparent sound barrier 2 is transparent safe doubling glass or transparent PC plate, and its thickness is 10mm.The present invention is rational in infrastructure, intensity is large, saves material, and lightweight, acoustically effective is good.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
