Abstract

The utility model discloses a kind of aluminum foaming sound-proof composite board, including board body, described board body is by surface layer, intermediate layer, bottom and packed layer are constituted, wherein, it is provided with intermediate layer between described surface layer and bottom, one group of projection upwards and downward projection the most equidistantly it is provided with in the upper and lower surface in described intermediate layer, and the plane domain of the upper and lower surface in described intermediate layer is respectively equipped with packed layer, before and after described board body, two ends are equipped with arc-shaped mounting groove, and the left and right sides of board body sets respectively by arc-shaped projection and arc-shaped groove.This utility model is by using the foamed board in honeycomb shape as packed layer, not only there is transmission and the sound-absorbing dual-use function intercepting sound, also there is stronger crushing resistance, in addition, by being provided with the projection upwards of interlaced difference and downward projection in the upper and lower surface in intermediate layer, sound can be carried out dispersion isolation, thus further increase the soundproof effect of this sheet material.

Description

A kind of aluminum foaming sound-proof composite board
Technical field
This utility model relates to machinery manufacturing technology field, is specially a kind of aluminum foaming sound-proof composite board.
Background technology
Along with the development of science and technology, China's rail transit vehicle equipment technology has obtained the development advanced by leaps and bounds, it has also become existing For city, intercity between main traffic instrument.Meanwhile, along with progress and the growth in the living standard of social civilization, people are not The only convenient, fast proposition requirements at the higher level to rail traffic vehicles, also to taking the safe, comfortable, reliable of rail traffic vehicles Propose the highest expectation.
It is known that the noise in reduction railway carriage is the effective way improving passenger's ride comfort.Track The interior noise main source of vehicle is vehicle chassis noise and cabin side pneumatic noise.At present, existing sound insulating sheet material is adopted more Make with organic and inorganic fiber, sponge, foamed board etc..But, existing rail vehicle mainly reduces chassis by Sound insulation floorings and makes an uproar Sound transmits, and the pneumatic noise of cabin side does not then have good solution.
Summary of the invention
The purpose of this utility model is to provide a kind of aluminum foaming sound-proof composite board, to solve to carry in above-mentioned background technology The problem gone out.
For achieving the above object, this utility model following technical scheme of offer: a kind of aluminum foaming sound-proof composite board, including Board body, described board body is made up of surface layer, intermediate layer, bottom and packed layer, wherein, sets between described surface layer and bottom There is intermediate layer, the upper and lower surface in described intermediate layer is the most equidistantly provided with one group of projection upwards and downward convex Rise, and the plane domain of the upper and lower surface in described intermediate layer is respectively equipped with packed layer, before and after described board body two End is equipped with arc-shaped mounting groove, and the left and right sides of board body sets respectively by arc-shaped projection and arc-shaped groove.
Preferably, all by glue and use hot pressing mode to be combined between described surface layer, intermediate layer, bottom and packed layer Overall platy structure.
Preferably, described surface layer, intermediate layer, bottom are all set to aluminium plate matter.
Preferably, described packed layer is set to the foamed board in honeycomb shape.
Preferably, the projection upwards on described intermediate layer and the interlaced arrangement of downward projection.
Compared with prior art, the beneficial effects of the utility model are: 1, by using the foamed board in honeycomb shape to make For packed layer, not only there is transmission and the sound-absorbing dual-use function intercepting sound, also there is stronger crushing resistance;2, by centre The upper and lower surface of layer is provided with the projection upwards of interlaced difference and downward projection, can come from internal with Sound wave in external environment condition carries out dispersion isolation, thus further increases the soundproof effect of this sheet material;3, by being provided with circular arc Shape projection and arc-shaped groove, it is possible to increase the bonding surface area between sheet material, thus improve installation strength.
Accompanying drawing explanation

Fig. 3 is surface structure schematic diagram of the present utility model.
In figure: 1, surface layer;2, intermediate layer;3, bottom;4, packed layer;5, projection upwards;6, downward projection;7, circular arc Shape mounting groove;8, arc-shaped projection;9, arc-shaped groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figure 1 to Figure 3, this utility model provides following technical scheme: a kind of aluminum foaming sound-proof composite board, Including board body, described board body is made up of surface layer 1, intermediate layer 2, bottom 3 and packed layer 4, wherein, and described surface layer 1 He It is provided with intermediate layer 2 between bottom 3, the upper and lower surface in described intermediate layer 2 is the most equidistantly provided with one group of upwards convex Play 5 and downward projection 6, and the plane domain of the upper and lower surface in described intermediate layer 2 is respectively equipped with packed layer 4, described Before and after board body, two ends are equipped with arc-shaped mounting groove 7, and the left and right sides of board body sets respectively by arc-shaped projection 8 With arc-shaped groove 9.
Further, all by glue and use hot pressing mode between described surface layer 1, intermediate layer 2, bottom 3 and packed layer 4 It is combined into the platy structure of entirety, the steadiness of this composite board can be effectively improved;Described surface layer 1, intermediate layer 2, bottom 3 are all provided with For aluminium sheet material, the bending strength of whole plywood sheet structure can be improved;Described packed layer 4 is set to the foaming in honeycomb shape Plate, can improve the functions such as the insulation of this composite board, sound insulation;Projection 5 upwards on described intermediate layer 2 and downward projection 6 Interlaced arrangement such that it is able to more fully play the effect that sound wave is carried out dispersion isolation.
Of the present utility model it is improved by, by using the foamed board in honeycomb shape as packed layer 4, not only there is resistance The transmission of sound insulation sound and sound-absorbing dual-use function, also have stronger crushing resistance;By setting in the upper and lower surface in intermediate layer 2 There are the projection 5 upwards of interlaced difference and downward projection 6, the sound wave come from inside and outside environment can be entered Row dispersion isolation, thus further increase the soundproof effect of this sheet material;By being provided with arc-shaped projection 8 on this composite board With arc-shaped groove 9, it is possible to increase the bonding surface area between sheet material, thus improve installation strength.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art For, the technical scheme described in previous embodiment still can be modified by it, or enters wherein portion of techniques feature Row equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all should Within being included in protection domain of the present utility model.
