The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are launched explanation:
The utility model provides a kind of sound absorption and sound insulation complex sound barrier, and each component names is as follows: protruding connecting portion 1, depression connecting portion 2, sound absorption material card article 3, sound insulating material card article 4, sound absorption material clamp 5, rhone 6, kink 7.
Back plate main body 21, panel body 22, panel die mould groove 23, panel fixed part 24, tone-entering hole 25, backboard die mould groove 26, backboard fixed part 27.
Water-repellent layer 41, absorbent treatment 42.
As shown in Figure 1, for containing the noise barrier structure schematic diagram of hydrophobic nonwoven, sound enters acoustic absorptive member by the hole on the panel 35; Sound passes water-repellent layer 41 and contacts with absorbent treatment 42 that (described water-repellent layer 41 is made up of the hydrophobic nonwoven, described absorbent treatment 42 is made up of sound absorption material, sound absorption material adopts the rock cotton board of good moldability to do the sound absorption core), sound wave causes sound absorption material to produce the vibration friction, be converted into mechanical energy, thereby produce acoustically effective; The soundproof course 32 that is made of sound insulating material prevents that the acoustic energy that penetrates sound absorption material from continuing to penetrate, thereby improves the sound insulation property of assembly.
Sound absorption material coats with the hydrophobic nonwoven, prevents that effectively rainwater from entering core inside and causing weightening finish and reduce sound absorbing capabilities; Sound insulation sheet material effectively improves the whole sound insulation property of assembly, reduces the metal use amount.
Sound absorption material card article 3 and the sound absorption material that acoustic absorptive member is required of the sound absorption material clamp 5 in female groove 36 in the public groove 31 are fixed in the assembly; Jointly that acoustic absorptive member is the required sound barrier of sound insulating material card article 4 in the public groove 31 and female groove 36 is fixed; Rhone 6 is convenient in time the rainwater discharge that enters assembly; When assembly is connected with assembly, earlier weather strip is placed the weather strip draw-in groove place of the female groove connecting portion 2 that promptly caves in, link up and down with public groove again.
Public groove and female groove adopt the extrusion modling aluminium, the machining accuracy height, and structural strength is big, avoids because of bending the distortion that welding causes; Considered that sound absorption material fixes required parts, avoided the long-time back sound absorption core that uses to collapse, influenced result of use because of the generation of making moist; Increase the rhone design, in time discharged rainwater, avoided making moist of sound absorption material; Arch (bridge) type designs not only that enable voice is difficult to penetrate, and guarantees defening effect, can prevent that also weather strip from producing big displacement and produce and come off.
As shown in Figure 2, for containing the noise barrier structure schematic diagram of closed pore acoustic foam.
Sound enters acoustic absorptive member by the hole on the panel; Sound contacts with the acoustic foam layer of being made up of the closed pore acoustic foam 33, and sound wave and pore membrane bump and produce vibration, are converted into mechanical energy, thereby produces acoustically effective; Sound insulating material prevents that the acoustic energy that penetrates acoustic foam from continuing to penetrate, thereby improves the sound insulation property of assembly; Inner sound absorption material adopts the closed pore acoustic foam of waterproof, can directly directly wash with giant, saves artificial maintenance cost; Sound absorption material is to be mechanically anchored in the assembly non-secondary pollution and reusable edible.The structure of the public groove 31 of present embodiment, female groove 36, backboard 34, panel 35 and effect are with embodiment shown in Figure 1, in this no longer repeat specification.
Above content be in conjunction with concrete optimal technical scheme to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
