Detailed description of the invention
The utility model is divided into three parts from a structural point, i.e. Double-layer sound-insulation structure (comprising inner fireproof thermal-insulation layer), surperficial sound absorption construction and connection profile (comprising sub-connection section bar 7 and female connection profile 8).
Need frequency characteristic and the sound insulation factor requirement of absorption of noise according to fitting-out plate, design perforated plate thickness, piercing aperture, perforation pitch-row, aluminium honeycomb thickness, damping steel plate thickness, the parameters such as base plate thickness, get the raw materials ready according to parameter request.
As shown in Figure 1, successively base plate 6, inorfil cotton 5 and damping steel plate 4 are connected together with Wear Characteristics of Epoxy Adhesive by order from bottom to up, composition Double-layer sound-insulation structure.
With purl machine, melamine foamed plastic 3 is pressed into aluminium honeycomb 2, by perforated plate 1, with epoxy glue, (adhesive glue is except epoxy glue again, the heat-resistant adhesive that can be other types is alternative, such as organic silica gel) bond to above aluminium honeycomb, form surperficial sound absorption construction (i.e. absorbent treatment), inside cabin, improve the sound absorbing capabilities of fitting-out sheet material.Described perforated plate is Pierced Aluminum Plank, also can replace with other perforated metals, the main noise Frequency Design that the thickness of perforated plate, the aperture of perforation and pitch-row absorb as required.Melamine foamed plastic is filled in aluminium honeycomb, forms honeycomb absorbent treatment, forms honeycomb sound absorption construction.Melamine foamed plastic has excellent sound absorbing capabilities, possesses high temperature resistant and fire-retardant characteristic simultaneously.Aluminium honeycomb is on the one hand as braced structures, and its thin wall construction vibration Absorbable rod low-frequency noise, promotes the sound absorbing capabilities of honeycomb absorbent treatment further on the other hand.Aluminium honeycomb wall is thin-slab structure, effectively can absorb low-frequency noise, solves the defect that single sound absorption material effect of low-frequency sound absorption is not good.The perforation of perforated plate coordinates honeycomb sound absorption construction, can be improved the acoustically effective of CF by design.
Described damping steel plate and base plate form Double-layer sound-insulation structure (i.e. soundproof course), and inner inorfil cotton of filling can promote the sound insulation property of sheet material further; Damping layer can suppress the vibration of steel plate, improves the defening effect in sheet material resonance region and identical district, and the thickness of steel plate requires design according to sound insulation.Described damping steel plate and base plate form Double-layer sound-insulation structure, and it is cotton to fill inorfil therebetween, and the sound of Absorbable rod interreflection between the two plates, promotes the sound insulation property of sheet material further.The damping layer of damping steel plate, effectively can improve the sound insulation factor in sound insulation curve resonance region and identical district, thus promotes overall sound insulation property.
Inorfil cotton can be rock wool, can be glass wool, also can be nanoporous aerogel, and this material also possesses the effect of fire prevention and insulation simultaneously, forms fireproof thermal-insulation layer.Described connection profile is divided into sub-connection section bar and female connection profile, receives the two ends of described combined plate respectively with Wear Characteristics of Epoxy Adhesive, for realizing convenient and seamless connection during actual installation.Sub-connection section bar and the connected mode of female connection profile are that falcon type is connected, and C type also can be adopted to connect.
Being bonded together the damping steel plate of Double-layer sound-insulation structure with epoxy glue above with below described surperficial sound absorption construction, by perforated plate, be filled with the aluminium honeycomb of melamine foamed plastic, damping steel plate, inorfil cotton and base plate are bonded together successively, form combined plate.Sub-connection section bar and female connection profile are steel section.Combined plate two ends are bonding with sub-connection section bar and female connection profile epoxy glue respectively, form final product, as shown in Figure 1.
During actual use, connected by the falcon type of connection profile and can realize installing easily, as shown in Figure 2.During construction, fire prevention sound absorption and insulation fitting-out plate is connected with the falcon type of female connection profile by the sub-connection section bar at two ends, and the continuous seamless that can realize combined plate is installed, not only reliable but also attractive in appearance.The utility model possesses good sound absorption simultaneously, sound insulation, fire-resistant, and the effect of insulation and decoration, is applicable to the interior trim of senior ship's space.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., be all included within protection domain of the present utility model.
