Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ceilings, in particular to a sound-insulating composite ceiling. Background Art

[0002] Aluminum ceilings are used as decorative roofing materials, shielding indoor pipelines, beams, columns, and keels, playing a vital role in home renovation. Existing aluminum ceilings have a relatively simple structure and a single function, primarily serving a decorative purpose. In modern commercial housing and office buildings, demand for sound insulation between floors is increasingly demanding, and traditional aluminum ceilings are unable to meet these requirements. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a sound-insulating composite ceiling.

[0004] The technical solution of this utility model is a soundproof composite ceiling comprising an aluminum shell, a frame, and a sponge board. A removable sponge board is installed within the aluminum shell, and the space between the sponge board and the inner wall of the aluminum shell is filled with sound-insulating filler. The sides of the aluminum shell are provided with a frame, and the inner wall of the aluminum shell is coated with a noise-reducing coating. Both sides of the aluminum shell have corrugated surfaces, and the sides of the sponge board where they contact the sound-insulating filler have serrated surfaces.

[0005] Furthermore, both ends of the aluminum shell are open, and sliding grooves are provided on both inner walls of the aluminum shell, and side edges matching the sliding grooves are provided on both side surfaces of the sponge board.

[0006] Furthermore, the outer surface of the corrugated surface is provided with a plurality of reinforcing ribs at even intervals.

[0007] Furthermore, the inner wall of the aluminum shell is provided with a plurality of symmetrically distributed and evenly spaced partitions, which separate the sound insulation fillers.

[0008] Furthermore, a plurality of evenly distributed countersunk holes are provided on the side of the frame, countersunk screws are provided in the countersunk holes, and threaded holes are provided on the side of the aluminum shell at positions corresponding to the countersunk screws.

[0009] Furthermore, the outer side surfaces in the width direction of the frame are respectively provided with shape-matched transverse positioning blocks and transverse positioning grooves; the outer side surfaces in the length direction of the frame are respectively provided with shape-matched vertical positioning blocks and vertical positioning grooves.

[0010] Furthermore, the shapes of the horizontal positioning block and the vertical positioning block or the horizontal positioning groove and the vertical positioning groove are different.

[0011] Compared with existing technologies, the advantages of this utility model are: the noise-reducing coating applied to the inner wall of the aluminum shell prevents loss of the coating due to scratches; the noise-reducing coating also blocks the propagation of sound waves. The corrugated surface of the aluminum shell facilitates sound reflection, reducing the effect of sound waves penetrating the ceiling. The sound waves that partially penetrate the aluminum shell are further attenuated by the sound-insulating filler. The sponge board's easily machined serrated surface increases the contact surface with the sound-insulating filler, enhancing the sponge board's sound absorption effectiveness.

[0020] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0021] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0022] like Figures 1 to 6 As shown, a soundproof composite ceiling includes an aluminum shell 1, a frame 2 and a sponge board 3. A removable sponge board 3 is provided in the aluminum shell 1, and a frame 2 is provided on the side of the aluminum shell 1. The frame 2 is made of rubber. The space between the sponge board 3 and the inner wall of the aluminum shell 1 is filled with sound insulation filler. Common sound insulation materials include glass fiber cotton or polystyrene foam. The sound insulation filler plays a role in attenuating sound waves. The inner wall of the aluminum shell 1 is plated with a noise reduction coating 12. The noise reduction coating 12 on the inner wall is not easy to wear and can prevent the further propagation of sound. Corrugated surfaces 11 are provided on both sides of the aluminum shell 1. The corrugated surfaces 11 facilitate the aluminum shell 1 to reflect sound waves and reduce the penetration effect of sound waves on the ceiling. The side of the sponge board 3 in contact with the sound insulation filler is provided with a serrated surface 31. The sponge board 3 uses the serrated surface 31 to increase the contact area with the sound insulation filler, further improving the sound absorption effect of the sponge board 3.

[0023] The two ends of the aluminum shell 1 are open, and the inner walls on both sides of the aluminum shell 1 are provided with a slide groove 13, and the two side surfaces of the sponge board 3 are provided with side edges 32 that match the slide groove 13. The sponge board 3 passes through the open end of the aluminum shell 1 and enters the interior of the aluminum shell 1 along the slide groove 13. The interior of the sponge board 3 is provided with a hard skeleton 33 in the transverse and longitudinal directions. The skeleton 33 improves the strength of the sponge board 3, so that the sponge board 3 maintains its shape and maintains a good sound absorption effect. The outer surface of the corrugated surface 11 is provided with a plurality of evenly spaced reinforcing ribs 111. The reinforcing ribs 111 improve the deformation resistance of the corrugated surface 11 without increasing the thickness of the outer wall of the aluminum shell 1. The inner wall of the aluminum shell 1 is provided with a plurality of symmetrically distributed and evenly spaced partitions 14. The partitions 14 separate the sound insulation fillers so that the sound insulation fillers are evenly distributed inside the aluminum shell 1, so that the sound insulation effects of various parts of the ceiling remain consistent.

[0024] The side of the frame 2 is provided with a plurality of evenly distributed countersunk holes 241, and countersunk screws 24 are provided in the countersunk holes 241. The side of the aluminum shell 1 is provided with threaded holes corresponding to the positions of the countersunk screws 24. The frame 2 is fixedly connected to the aluminum shell 1 by the countersunk screws 24. The outer side surface of the frame 2 in the width direction is provided with shape-matched horizontal positioning blocks 22 and horizontal positioning grooves 221, respectively. Adjacent composite ceilings can be spliced in the width direction through the horizontal positioning blocks 22 and horizontal positioning grooves 221; the outer side surface of the frame 2 in the length direction is provided with shape-matched vertical positioning blocks 231 and vertical positioning grooves 23, respectively. Adjacent composite ceilings can be spliced in the length direction through the protruding vertical positioning blocks 231 and vertical positioning grooves 23. The frame 2 is connected to the aluminum shell 1 using countersunk screws 24, which facilitates the fitting of the frames 2 of different composite ceilings and prevents the formation of gaps. The horizontal positioning block 22 and the vertical positioning block 231 or the horizontal positioning groove 221 and the vertical positioning groove 23 have different shapes, which makes it easy to quickly distinguish the horizontal and vertical directions of the ceiling, thereby quickly splicing different ceilings at relative positions.

[0025] The working principle of this embodiment of the utility model is as follows: different composite ceiling panels can be spliced together via the frame 2 to adapt to different usage scenarios. Sound waves are transmitted to the corrugated surface 11 of the aluminum shell 1, with some being reflected by the corrugated surface 11 and some passing through the aluminum shell 1. The noise-reducing coating 12 and sound-insulating filler prevent the sound from passing through the aluminum shell 1 from further propagation, and the sponge board 3 further absorbs the sound.
