Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing panels, in particular to a fireproof sound-absorbing panel which is not easy to fall off. Background Art

[0002] Polyester fiber sound-absorbing board is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, heat preservation, moisture resistance, mildew resistance, easy dust removal, parquet, simple construction, good stability, good independence, high cost performance, etc. There are a variety of colors to choose from, which can meet the needs of sound-absorbing decoration of different styles and levels. It is often used in concert halls, theaters, recording studios, studios, monitoring rooms, conference rooms, gymnasiums, exhibition halls, dance halls, KTV rooms and other occasions.

[0003] For example, Chinese patent CN218713907U discloses a fireproof and environmentally friendly polyester fiber sound-absorbing board, which specifically relates to the technical field of sound-absorbing boards, including a central base layer, a first reinforcement layer is arranged on one side of the central base layer, a first insulation layer is connected to the outside of the first reinforcement layer, a first sound-absorbing layer is connected to the outside of the first insulation layer, a first fireproof layer is connected to the outside of the first fireproof layer, and a first anti-corrosion layer is connected to the outside of the first fireproof layer. It can improve the fireproof performance and anti-corrosion performance, but because some layers are fixed by bonding, after long-term use, the adhesive may gradually age due to environmental factors such as temperature, humidity, ultraviolet rays, etc., and lose the original bonding strength, resulting in loosening or falling off between layers, which will cause the performance of the sound-absorbing board to decline and fail to meet the use requirements.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a fireproof sound-absorbing board that is not easy to fall off, so as to overcome the above-mentioned technical problems existing in the existing related technology.

[0006] To this end, the specific technical solutions adopted by the utility model are as follows:

[0007] A fireproof sound-absorbing panel that is not easy to fall off comprises a frame, the interior of the frame is a hollow structure, and cover plates are arranged on both sides of the frame. A polyester fiber board, a foam board, a sound-absorbing board and a waterproof and anti-seepage board are arranged in sequence inside the frame; a decorative layer is arranged on one side of the frame, and the frame and the cover plate are connected by bolts.

[0008] Furthermore, in order to improve the fireproof performance of the sound-absorbing panel, when a fire occurs, the coating can effectively prevent the spread of flames, making the sound-absorbing panel safer and more reliable when a fire occurs, thereby protecting the building structure and personnel safety. The surface of the frame and the cover plate are provided with a fireproof coating.

[0009] Furthermore, in order to cause multiple reflections and scattering of sound when it propagates inside the chamber, thereby consuming sound energy and improving the sound absorption effect, the resonance ball is combined with the spring to form a dynamic sound absorption structure. When the sound wave encounters this structure, it will be effectively absorbed and converted, thereby reducing the reflection and propagation of the sound. A number of chambers are opened inside the foam board, a resonance ball is arranged in the middle of the chamber, and a number of springs are arranged on the outside of the resonance ball; the several springs are arranged in a cross shape, and one end of the spring is fixedly connected to the inner wall of the chamber.

[0010] Furthermore, in order to achieve further absorption of sound, the trapezoidal structure of the silencer block can capture sound waves more effectively, and convert sound waves into heat energy or other forms of energy through its special shape and material, thereby further reducing the reflection and propagation of sound. A number of mounting grooves are provided on the side wall of the silencer board, a mounting plate is provided inside the mounting groove, and a number of silencer blocks are provided on one side of the mounting plate; the cross-section of the silencer block is a trapezoidal structure, and the several silencer blocks are arranged in a matrix.

[0011] Furthermore, in order to realize the installation of the frame and the cover plate, bolt holes matching with the bolts are symmetrically provided at the top and bottom ends of the side walls at both ends of the frame.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model has a reasonable and reliable structure. The fireproof sound-absorbing board that is not easy to fall off can be installed on various layers through a frame, which can ensure that the sound-absorbing board will not fall off between the layers due to the failure of the bonding strength after long-term use, thereby ensuring the durability of the sound-absorbing board. At the same time, the setting of the fireproof coating can improve the fireproof performance of the sound-absorbing board. When a fire occurs, the coating can effectively prevent the spread of the flame, making the sound-absorbing board safer and more reliable when a fire occurs, thereby protecting the building structure and personnel safety.

[0014] 2. By setting up the foam board, the sound will be reflected and scattered multiple times when it propagates inside the chamber, which consumes sound energy and improves the sound absorption effect. The resonant ball and spring are combined to form a dynamic sound-absorbing structure. When the sound wave encounters this structure, it will be effectively absorbed and converted, thereby reducing the reflection and propagation of the sound.

[0015] 3. By setting up the silencer board, the sound is further absorbed. The trapezoidal silencer block can capture the sound waves more effectively, and convert the sound waves into heat energy or other forms of energy through its special shape and material, further reducing the reflection and propagation of the sound.

Figure 1-Figure 5As shown, the fireproof sound-absorbing panel that is not easy to fall off according to the embodiment of the utility model includes a frame 1, the interior of the frame 1 is a hollow structure, and cover plates 2 are arranged on both sides of the frame 1, and a polyester fiber board 3, a foam board 4, a sound-absorbing board 5 and a waterproof and anti-seepage board 6 are arranged in sequence inside the frame 1; a decorative layer 7 is arranged on one side of the frame 1, the frame 1 and the cover plate 2 are connected by bolts 8, and the surfaces of the frame 1 and the cover plate 2 are provided with fireproof coatings, and bolt holes 101 matching with the bolts 8 are symmetrically opened at the top and bottom ends of the side walls at both ends of the frame 1.

[0027] In addition, it should be noted that polyester fiberboard is a board made of polyester resin as the main base material, by adding a certain proportion of hardener and additives. Polyester fiberboard has the characteristics of lightness and its density is much lighter than concrete, which is beneficial to reduce the weight of the building structure.

[0028] Fireproof coating uses silicate cement as the base material, which is an environmentally friendly material. Since silicate cement itself has good fire resistance, its refractoriness can reach over 1000 degrees Celsius. This allows the fireproof coating based on silicate cement to maintain stability in high temperature environments and effectively prevent the spread of fire.

The fireproof sound-absorbing panel that is not easy to fall off can realize the installation of various layers through the frame 1, which can ensure that the sound-absorbing panel will not fall off between the layers due to the failure of the bonding strength after long-term use, thereby ensuring the durability of the sound-absorbing panel. At the same time, the setting of the fireproof coating can improve the fireproof performance of the sound-absorbing panel. When a fire occurs, the coating can effectively prevent the spread of flames, making the sound-absorbing panel safer and more reliable when a fire occurs, thereby protecting the building structure and personnel safety.
