Technical field
The utility model is specifically related to a kind of bamboo facing sound-absorbing composite board that has good sound-absorbing performance, prevents dewfall.
Background technology
Sound absorbent perforated structure is a kind of resonance sound-absorbing structure, and near this structure sound absorption coefficient resonance frequency is bigger, the off-resonance frequency, and then sound absorption coefficient sharply descends.In order to increase the sound absorption coefficient of sound absorbent perforated structure, widen its sound sucting band, conventional way is the chamber of behind plate, leaving a blank, and in cavity all or close adhesion plate fill certain thickness porous absorption material.Factors such as perforated plate thickness, perforated percentage (comprising pass, aperture and pitch-row), cavity depth, porous absorption material thickness all can influence resonance frequency and sound sucting band width.Usually, absorb sound by force in order to realize wideband, the perforation board resonance sound absorption structure gross thickness is generally 75mm ~ 150mm.Take the interior space so, first; In addition then some porous sound-absorbing materials (like centrifugally glass-wool) tend to cause symptoms such as the constructor is allergic; Moreover to fill compactness not enough for porous absorption material in the work progress, even some positions phenomenon of using inferior materials and turning out substandard goods also often has generation, thereby influenced acoustic efficiency greatly.
Along with the policy guidance of national green building, the green construction theory also becomes a very important notion.Therefore be necessary with the integrated innovation to be guidance, theories such as comprehensive acoustic efficiency, thermal property, decorative effect, finished product production, green construction are designed a kind of novel bamboo facing sound-absorbing composite board.
Summary of the invention
In view of this, the purpose of the utility model provide a kind ofly have good sound-absorbing performance, prevent dewfall, convenient, the specious bamboo facing sound-absorbing composite board of construction.
The purpose of the utility model realizes through following technical scheme:
As shown in the figure; Said bamboo facing sound-absorbing composite board is a layer structure, comprises perforation bamboo finish coat, Pierced Aluminum Plank, composite bed, connector and FC plate, and perforation bamboo finish coat is set on the one side of said Pierced Aluminum Plank; Together as the acoustical board external surface; The another side of said Pierced Aluminum Plank is close to composite bed, is provided with a plurality of connectors between said composite bed and the FC plate, and constitutes cavity body structure through the connector between; Form an air layer, be provided with the cotton plate of the sound absorption of being close to composite bed in the cavity body structure.
Further, the cotton plate of said sound absorption closely is connected with composite bed;
Further, said composite bed is the composite bed of plastic sheeting and fire retardant nonwoven fabric;
Further, a termination of said connector is passed composite bed and is closely linked to each other with Pierced Aluminum Plank, and another termination closely links to each other with the FC plate;
Further, said FC plate is provided with rivet hole;
Further, said rivet hole runs through the connecting portion of FC plate and connector;
Further, the density of such perforation of said Pierced Aluminum Plank is 2.7g/cm
3
The beneficial effect of the utility model is:
1) owing to adopts the Pierced Aluminum Plank of little perforated percentage; Near the perforation Particle Vibration Velocity strengthens (than large perforation rate perforated plate); Thereafter the cotton plate of being close to of additional sound absorption has significantly increased the additional acoustic resistance of perforate tip again; Thereby improved the acoustically effective of structure, acoustic efficiency (comprising sound absorption and sound insulation) is good;
2) be provided with composite bed at perforated plate and sound absorption between the cotton plate, the fibre composition of the cotton plate that can prevent first to absorb sound escapes; In addition then, can infiltrate by block water steam, prevent the material layer internal condensation;
3) be provided with seal cavity between composite bed and the FC plate, improved the heat insulating effect and the defening effect of composite board, thermal property has better improvement;
4) perforation bamboo finish coat is set on the surface of Pierced Aluminum Plank, decorative effect is good, has improved the overall appearance degree, adopts the bamboo wood material simultaneously, and environment protecting is good;
5) convenient, the reduction of erection time of construction, it is less to account for the interior space.
Other advantages, target and the characteristic of the utility model will be set forth in manual subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model and other advantages can realize and obtain through following manual and claims.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Fig. 1 is the cross-sectional view of the utility model;
Fig. 2 is the construction view of the utility model.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.Should be appreciated that preferred embodiment has been merely explanation the utility model, rather than in order to limit the protection domain of the utility model.
As shown in the figure, bamboo facing sound-absorbing composite board is a layer structure, comprises perforation bamboo finish coat 1, Pierced Aluminum Plank 2, composite bed 3, connector 4 and FC plate 7, and the density of such perforation of Pierced Aluminum Plank is 2.7g/cm
3Perforation is set on the one side of Pierced Aluminum Plank lives finish coat 1; Both are together as the acoustical board external surface; The another side of Pierced Aluminum Plank is close to composite bed 3, in the present embodiment, is provided with a plurality of connectors 4 between composite bed 3 and the FC plate 7; One termination of connector 4 is passed composite bed and is closely linked to each other with Pierced Aluminum Plank 2, and another termination closely links to each other with the FC plate.And constitute cavity body structure through connector 4 betweens, form an air layer, be provided with in the cavity body structure and the cotton plate 5 of the composite bed 3 folded sound absorptions that connect.
