Description
Technical field:
The utility model relates to the noise insulation equipment technical field, is specifically related to a kind of novel compound plate for noise barrier of aluminium honeycomb+foamed aluminium.
Background technology:
In daily life, various plant equipment, automobile, train, subway, the operation of the vehicles such as aircraft, use the various engineerings of weight equipment, and the use of various stereo sets or the like, all can bring noise, excessive noise can make the people not feel well, tinnitus appears, stomachache, symptoms such as dysphoria, thus be detrimental to health.Production department then can be because of operating environment badly cause the low and product quality decline of production efficiency.
Therefore, at first to try every possible means the noise of noise source is reduced as far as possible, will intercept noise as far as possible to external communication if can not reduce.This needs are embodied in production department, the road on both sides of the road, construction site, inhabitation that the heavy equipment operation is adjacent and office space, and theater, indoor sport shop, various public places of entertainment.
Generally, as the sound-screen system, the main employing has sound-absorbing or sound insulation materials with function, makes various sound barriers, noise barrier, and quiet room etc. are to reach the purpose of sound-absorbing and sound insulation.Generally speaking, widely used sound-screen material mainly contains timber, building materials or sponges such as concrete, synthetic resin materials such as foamed plastics, or glass wool, inorganic material such as rock wool, and metal material such as metal perforated board, the independent or compound use of above material.
How many sound-screen materials can be distinguished to some extent because of the different of field of employment and purposes, but requires to have good suction/soundproof effect mostly, and favorable mechanical performance such as durability, heat resistance are not fired or flame retardancy, low production cost, characteristics such as construction and easy maintenance.Its positive bending plate or perforated boards that adopt metal of the sound barrier of the more use in roadside, road at present more, perforated board is greatly affected sound-absorbing effect because of the low reflection that causes noise of punching ratio, and its intensity and durability are also relatively poor, easy deformation or breakage.
In order to reach sound-absorbing effect, damping material such as glass wool or rock wool must be filled in the inside of this metal sheet, though it is all right that the initial stage sound-absorbing effect is installed, but after after a while, because of rainwater, moisture, the sinking that the influence of wind-force and deadweight produce, make sound-absorbing effect be subjected to very big influence, application life is extremely limited.And the steel plate that use at the back side of sound barrier, the corrosion phenomenon can appear in long-term use, influences attractive in appearance and structural strength.
The metal sheet sound barrier has to use more H shaped steel as fixed support because of the reason of its weight when mounted, and general 2 meters just need a pillar, and the requirement of strength of pedestal is also very high.Operating expenses is bigger.
Other, as the sound barrier of wood materials, Master Cost and operating expenses are all higher, and application life is shorter.And synthetic resin material fireproof performance is relatively poor and yielding.In order to increase glass wool or the rock wool that sound-absorbing effect uses, can produce environment pollution and non-renewable utilization.
The utility model content:
The purpose of this utility model provides a kind of novel plate for noise barrier, and it overcomes the defective of existing sound barrier sheet material, adopts foamed aluminium board and the compound mode of aluminum honeycomb panel, when guaranteeing suction/soundproof effect, has high strength, low weight, durability and fire prevention, characteristics such as waterproof.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises aluminium keriotheca 20 and foamed aluminium layer 30, it also comprises insulation material layer 40 and glued membrane 50, aluminium keriotheca 20 1 sides are by glued membrane 50 composite foam aluminium laminations 30, and opposite side is by glued membrane 50 composite sound isolating material layers 40.
Described aluminium keriotheca 20 is for to make the aluminium honeycomb lamellar structure that hexagon has volume ratio 95%-99% cavity by thin aluminum sheet 22;
Described foamed aluminium layer 30 is to have sound absorption function, has the aluminum foam plate of a plurality of pores; The volume ratio of pore is 90%-99%.
Described insulation material layer 40 is the 0.3-2.0 millimeters thick, has steel plate, galvanized steel plain sheet, aluminium sheet, aluminium alloy plate, corrosion resistant plate and/or the nonmetal plate of deadening.
The utility model can be tackled the noise of wide range frequencies, and particularly its noise reduction of the low frequency noise below 500 hertz is better.Its ultralight, high strength, the characteristics of big specification make construction and safeguard that expense is cheap easily, and do not have dust and produce, can regeneration, can not burn, can not produce toxic gas during breaking out of fire.

Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of the specific embodiment two,
Fig. 3 is the structural representation of the specific embodiment three.
The specific embodiment:
The specific embodiment one: with reference to Fig. 1, this specific embodiment is by the following technical solutions: it comprises aluminium keriotheca 20 and foamed aluminium layer 30, it also comprises insulation material layer 40 and glued membrane 50, aluminium keriotheca 20 1 sides are by glued membrane 50 composite foam aluminium laminations 30, and opposite side is by glued membrane 50 composite sound isolating material layers 40.
Described aluminium keriotheca 20 is for to make the aluminium honeycomb lamellar structure that hexagon has volume ratio 95%-99% cavity by thin aluminum sheet 22;
Described foamed aluminium layer 30 is to have sound absorption function, has the aluminum foam plate of a plurality of pores; The volume ratio of pore is 90%-99%.
Described insulation material layer 40 is the 0.3-2.0 millimeters thick, has steel plate, galvanized steel plain sheet, aluminium sheet, aluminium alloy plate, corrosion resistant plate and/or the nonmetal plate of deadening.
The essential structure of this specific embodiment---plate for noise barrier 10 is composited with glued membrane 50 and foamed aluminium layer 30 and insulation material layer 40 respectively by the two sides of aluminium keriotheca 20.The aluminium keriotheca 20 of central authorities is made hexagon cellular shape 24 by aluminium sheet 22.
The specification of the aluminium keriotheca 20 that uses in this specific embodiment is selected according to the field of employment and the performance of sound barrier.For example the catercorner length of hexagon cellular shape 24 is the 6-50 millimeter, and the thickness height is the 10-240 millimeter, can freely adjust, and is unrestricted.
