Through actual research on the existing sound absorption and insulation plate, the existing sound absorption and insulation plate is mostly only about 30dB (A) of sound insulation effect, and the sound absorption and insulation plate with high noise reduction and low manufacturing cost is provided.
Most of sound absorption materials adopted by the existing sound absorption and insulation plate are glass wool, and then the sound absorption and insulation plate is wrapped by glass fiber cloth and placed between a steel plate and a pore plate. However, the sound insulation effect of the sound absorption and insulation board is not very excellent, and the glass wool is not cheap in the actual use process. Accordingly, a combined type sound absorbing and insulating panel having high sound insulating capacity is provided by those skilled in the art to solve the problems in the background art as described above.
Disclosure of Invention
The invention aims to provide a combined sound absorption and insulation board with high sound insulation capacity, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a combined sound absorption and insulation board with high sound insulation capacity comprises a sound absorption and insulation board body, wherein the sound absorption and insulation board body comprises a galvanized steel plate, an FC damping sound insulation layer, rock wool, a movable galvanized steel plate, K superfine glass fiber sound absorption cotton and a galvanized perforated plate;
galvanized steel sheet, FC damping sound insulation layer, rock wool, K superfine glass fiber inhale sound cotton and galvanized perforated plate and acoustic baffle body adopt fixed structural connection, but mobile galvanized steel sheet and acoustic baffle body swing joint.
As a further scheme of the invention: the sound absorption and insulation plate body is sequentially divided into a 1.5mm galvanized steel plate, a 2mm FC damping sound insulation layer, a 50mm rock wool, a 1.5mm movable galvanized steel plate, a 48K superfine glass fiber sound absorption cotton and a 1.0mm galvanized perforated plate from left to right.
As a still further scheme of the invention: the rock wool and the 48K superfine glass wool are both formed by wrapping alkali-free hydrophobic glass fiber cloth.
Compared with the prior art, the invention has the beneficial effects that:
1. when the sound absorption board is used, the sound absorption material can fully absorb the noise of middle and high frequency bands by using the sound absorption material in a combined mode and installing the sound absorption material at a specific position, and the sound absorption effect of the sound absorption and insulation board is enhanced.
2. When the invention is used, the installation of the non-fixed galvanized steel plate increases the noise frequency bandwidth of the treatment, and the low-frequency noise can be treated. The function of the sound absorption and insulation plate is fully exerted, and the sound absorption and insulation effect of the sound absorption and insulation plate is effectively improved.
3. When the invention is manufactured, the original external body structure is not changed, and the installation mode is the same as the original mode, thereby effectively reducing the investment in the actual engineering, saving the cost, leading the engineering construction to be more convenient and simple, and providing reference and reference for the actual engineering design.
Drawings
Fig. 1 is a schematic structural view of a combined sound absorption and insulation board with high sound insulation capacity.
In the figure: 1. a sound absorption and insulation board body; 2. a galvanized steel sheet; 3. an FC damping sound insulation layer; 4. rock wool; 5. a non-fixed galvanized steel sheet; 6. 48K superfine glass sound-absorbing cotton; 7. a galvanized perforated plate.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, in the embodiment of the present invention, a combined sound absorption and insulation board with high sound insulation capacity includes a sound absorption and insulation board body 1, where the sound absorption and insulation board body 1 includes a galvanized steel plate 2, an FC damping sound insulation layer 3, rock wool 4, a movable galvanized steel plate 5, a 48K ultra-fine glass fiber sound absorption cotton 6, and a galvanized perforated plate 7;
inhale sound insulation board body 1 and divide into 1.5mm galvanized steel sheet 2 from a left side to the right side in proper order, 2mmFC damping sound insulation layer 3, 50mm rock wool 4, 1.5mm mobile galvanized steel sheet 5, sound cotton 6 and 1.0mm galvanized steel sheet 7 are inhaled to 48K superfine glass fiber, and galvanized steel sheet 2, FC damping sound insulation layer 3, rock wool 4, 48K superfine glass fiber inhales sound cotton 6 and galvanized steel sheet 7 and adopts fixed structural connection with sound insulation board body 1, mobile galvanized steel sheet 5 and sound insulation board body 1 swing joint, it all adopts alkali-free glass fiber cloth parcel to form to inhale rock wool 4 and 48K superfine glass cotton 6.
The working principle of the invention is as follows:
when the sound absorption and insulation board is used, sound absorption is carried out through the rock wool 4 with the thickness of 50mm and the glass wool 6 with the thickness of 50mm, the sound absorption and insulation board structure is distributed at a specific position through different materials, the noise of a middle and high frequency range is fully absorbed through material combination, meanwhile, the noise frequency bandwidth of treatment is increased through the installation of the non-fixed galvanized steel plate 2, and the noise of the middle and low frequency range can be treated. The function of the sound absorption and insulation plate is fully exerted, and the sound absorption and insulation effect of the sound absorption and insulation plate is effectively improved;
meanwhile, because the cost of rock wool is basically lower than that of glass wool in the existing market, the investment cost is reduced under the condition of ensuring the high sound insulation quantity of the novel sound absorption and insulation plate;
and the design of the sound absorption and insulation plate does not change the appearance structure of the original sound absorption and insulation plate, compared with the installation of the original sound absorption and insulation plate, other processes are not added in the construction and installation process, the installation mode is the same as the original installation mode, but the sound absorption and insulation effect is obviously improved, meanwhile, the investment is effectively reduced in the actual engineering, the cost is saved, and reference are provided for the actual engineering design.
