Abstract
The invention provides a marine noise reduction structure. A hollow special-shaped glass fiber cloth, an aluminum foil and a dressing layer are sequentially laid on a horizontal steel deck. By virtue of adopting a composite structure, vibration and noises of a ship can be greatly weakened or eliminated. The hollow glass fiber cloth has the advantages of non-combustible property, verminproof property, heat resistance, corrosion resistance, high strength, high sound absorption coefficient and the like. Due to the aluminum foil, the corrosion resistance of a material is greatly improved, the water vapor obstruction effect is enhanced, the tensile strength is better, and the veneering is relatively stiff, smooth and flat; the dressing layer comprises an inorganic binder and a dressing main body and can be used for effectively protecting the deck and achieving antirust and antiwear effects.
Description
Technical field
The present invention relates to ship deck structure, especially a kind of denoising structure peculiar to vessel.
Background technology
The European Union of requirement according to International Maritime Organization (IMO) (IMO) and to(for) the level of noise in ship's space, its volume can not exceed 55 decibels, once exceed 55 decibels, can cause harmful effect to crewman's daily life life.At present, in the cabin of boats and ships, there is plurality of devices, these equipment can produce vibrations and a large amount of noise in the time of operation, have a strong impact on other living environment on the living environment of the habitation on working environment and the deck adjacent with cabin in cabin and ship, therefore in Ship Building and Repairing process, carry out to boats and ships steel deck the design of shock-reducing and noise-reducing structure.
At present, the connection of boats and ships cabin structure all belongs to and is rigidly connected, the vibrations and the noise that when effectively reduction equipment moves, produce, therefore, in the time that cabin district equipment moves, the sharp pounding of its generation and noise are delivered to strut member, suspender member and low groove by hull structure, be delivered to again on wallboard and top ceiling, thereby make boats and ships habitation produce sharp pounding and serious noise emission, badly influence habitation crewman's life, do not meet IMO and the European Union regulation for ship's space level of noise, live for a long time, will have a strong impact on habitation crewman's physiology and mental health.In addition, though the floating fire-resistant deck covering structure of lower tween deck setting can reach certain damping noise reduction effect, but have little effect, it absorbs vibration and the poor effect of noise, be difficult to hull structure transmission and the vibration that comes and reducing noise to IMO and European Union the specialized range to ship's space level of noise.
Summary of the invention
The defect existing for prior art, the object of this invention is to provide a kind of denoising structure peculiar to vessel, be a kind ofly there is high acoustic absorption, do not fire, the denoising structure peculiar to vessel of heat-resisting, withstanding corrosion, the advantage such as high-strength.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of denoising structure peculiar to vessel is laid with successively hollow profile glass fabric, aluminium foil and dressing layer on the steel deck of level.
Further, the triangle that described hollow profile glass fabric is MULTILAYER COMPOSITE or pentagon hollow fiber cloth, thickness is 8 ~ 10mm.Hollow profile glass fabric have do not fire, the advantage such as mothproof, heat-resisting, withstanding corrosion, high-strength, high acoustic absorption coefficient, and due to the open structure feature of its hollow profile, in fabric micropore, be detained and have air, make it have good acoustic impedance, in the time that sound wave enters glass fabric inside, due to the effect of sound field, cause interstitial air vibration, due to friction, cold air viscous resistance etc., make a part of acoustic energy be converted into heat energy and be absorbed.
Described aluminum foil thickness is 7 ~ 9 μ m, carry out hot pressing by polyethylene hot blast laminating method and hollow profile glass fabric compound, the compound hollow profile glass fabric of aluminium foil forming has solved the defect of the larger permeability to air of single glass lamination coating, has taken into account the two kind performances of the present invention's sound absorption with sound insulation.Meanwhile, described aluminium foil improves material corrosion resistance greatly, and moisture obstruction is strengthened, and tensile strength is better, and veneer is more well-pressed, smooth.
Described dressing layer comprises inorganic bond layer and dressing body layer, and the thickness of described inorganic bond layer is 0.45 ~ 0.55mm, and the thickness of described dressing body layer is 40 ~ 45mm.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is composited by four layer materials, and compound after vibration and noise significantly weaken or eliminate.Hollow profile glass fabric have do not fire, the advantage such as mothproof, heat-resisting, withstanding corrosion, high-strength, high acoustic absorption coefficient; Aluminium foil improves material corrosion resistance greatly, and moisture obstruction is strengthened, and tensile strength is better, and veneer is more well-pressed, smooth; Dressing layer comprises mineral binder bond and dressing main body, can effectively protect deck, reaches antirust, wear-resisting effect.
