Abstract
The invention discloses a sound absorption and noise reduction process for a metal roof of a building with super-large space. The sound absorption and noise reduction process is characterized in that a steel lining plate is arranged on the lowermost layer of a roof structure, an aluminum-magnesium-manganese alloy roof panel is arranged on the uppermost layer of the roof structure, holes are formed in the lining plate, the punching rate is 21%, the diameter of each hole is 24mm, an anti-noise layer and a sound-insulation layer are sequentially arranged below the aluminum-magnesium-manganese alloy roof panel, the anti-noise layer is made of ultrafine glass cotton, and the sound-insulation layer is a gypsum fiber board. The sound absorption and noise reduction process has the advantages that a sound-insulation effect is realized for an outer layer of the roof by solid, a sound absorption structure is arranged on an inner layer of the roof, and accordingly outdoor noise is prevented from being transmitted into a room.
Description
Technical field
The present invention relates to super large space structural metal roof sound absorption reduction technology.
Background technology
Design for super large space building interior sound insulation function, because dropping on the roof panel, rainwater can produce impact sound to roof panel, because wind action also may be created in the wind song on the roof, perhaps other outdoor noises all finally can pass to indoor by garret simultaneously.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of super large space structural metal roof sound absorption reduction technology, and it is indoor to avoid outdoor noise to pass to.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: super large space structural metal roof sound absorption reduction technology, the roof construction orlop is the interior lining panel of steel, the roof construction the superiors are the Al-Mg-Mn alloy roof panel, it is characterized in that: punch at interior lining panel, perforated percentage is 21%, aperture 24mm, set gradually anti-noise layer and puigging below the Al-Mg-Mn alloy roof panel, described anti-noise layer is superfine glass silk floss, and described puigging is plasterboard.
Preferably, above interior lining panel, lay nonwoven and superfine glass silk flosssilk wadding successively.
Preferably, the unit weight of described superfine glass silk flosssilk wadding is 12Kg, the superfine glass silk flosssilk wadding of being close to the Al-Mg-Mn alloy roof panel in construction by the thick 15mm of being densified to of 30mm, the superfine glass silk flosssilk wadding that nonwoven is close in the interior lining panel top in construction by the thick 30mm of being densified to of 50mm.
Preferably, the thickness of described interior lining panel is 0.5mm, and the thickness of described Al-Mg-Mn alloy roof panel is 0.9mm.
Preferably, the thickness of described plasterboard is 12mm.
The present invention at first adopts solid-borne sound sound insulation measure, by increasing the damping action of plate, improve the sound insulation factor of coincidence frequency, thereby the paddy that coincide is shoaled, namely at the bottom of roof panel, lay the thick superfine glass cotton material of 30mm, then by in design and construction, glass wool being compressed to 15mm, thereby make not only to be adjacent between plate and the glass wool but also to have and form certain pressure, so just be equivalent to paste one deck damping material at the bottom of plate, by evidence, this kind way can effectively lower the solid-borne sound noise.
In addition, the present invention is in the punching of roof construction orlop interior lining panel, and perforation steel sole plate and nonwoven, superfine glass silk flosssilk wadding constitute the sound-absorbing structure jointly, and test detects proof, and sound-absorption coefficient surpasses 0.85, satisfies building to the requirement of roof sound absorption qualities.
To sum up, the present invention takes solid sound insulation at the roof skin, and adopts the sound-absorbing structure at the roof internal layer, and final like this to have avoided outdoor noise to pass to indoor.
The specific embodiment
Specify super large space structural metal roof sound absorption reduction technology below, the roof construction orlop is the interior lining panel of steel, and the roof construction the superiors are the Al-Mg-Mn alloy roof panel.
At first, the present invention sets gradually anti-noise layer and puigging below the Al-Mg-Mn alloy roof panel, and described anti-noise layer is superfine glass silk floss, and described puigging is plasterboard.Described superfine glass silk flosssilk wadding is by the thick 15mm that is densified to of 30mm.The unit weight of described superfine glass silk flosssilk wadding is 12Kg.The thickness of described Al-Mg-Mn alloy roof panel is 0.9mm.The thickness of described plasterboard is 12mm.
Secondly, above interior lining panel, lay nonwoven and superfine glass silk flosssilk wadding successively.In order to improve acoustically effective, to punch at interior lining panel, perforated percentage is 21%, aperture 24mm.The thickness of described interior lining panel is 0.5mm.Described superfine glass silk flosssilk wadding is densified to below the 30mm by 50mm is thick.The unit weight of described superfine glass silk flosssilk wadding is 12Kg.
