Description

Technical Field

[0001] This utility model relates to the field of building decoration engineering technology, and in particular to a sound-absorbing and environmentally friendly ceiling structure. Background Technology

[0002] As modern architecture places increasing demands on acoustic environments, sound-absorbing ceiling structures are being used more and more widely in interior decoration. Traditional ceiling structures mainly focus on aesthetics and fire resistance, while their optimization of acoustic performance is relatively limited. With people's increasing demands for living environments, indoor sound insulation has become particularly important. In order to reduce indoor noise, a sound-absorbing and environmentally friendly ceiling structure is needed.

[0003] A search revealed Chinese patent publication number CN215442634U, which discloses a sound-insulating and sound-absorbing ceiling structure. This structure includes several mounting plates installed on the bottom wall of the ceiling, distributed circumferentially around the ceiling. A support plate is provided on the bottom surface of each mounting plate, and a hanging frame is mounted on each support plate. A buffer plate is provided on the side wall of the hanging frame near the mounting plate. This application places the hanging frame on the support plate, with buffer plates distributed around it. When noise is generated indoors, the hanging frame vibrates, compressing the buffer plates. The buffer plates are elastic, thus reducing the vibration intensity on the hanging frame and minimizing the vibration transmitted to the ceiling, effectively improving the noise reduction effect of the ceiling. However, in actual use, due to indoor sound vibrations, the hanging frame may loosen over time, making the connections weak and potentially causing it to detach, posing a safety hazard. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sound-absorbing and environmentally friendly ceiling structure, which aims to improve the existing technology of setting a hanging frame on the load-bearing plate and using a buffer plate for noise reduction. However, due to indoor sound vibration, the hanging frame will become loose and the connection will become weak after long-term use, leading to the hanging frame falling off and causing safety hazards.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sound-absorbing and environmentally friendly ceiling structure, including a main keel, with a secondary keel fixedly connected to the outer wall of the main keel around its perimeter. Screws are threadedly connected to the four corners of the top of the secondary keel. A sound-absorbing substrate is provided at the bottom of the secondary keel, with a sealing ring fixedly connected to the top of the sound-absorbing substrate. A decorative panel is fixedly connected to the bottom of the outer wall of the sound-absorbing substrate, and a fireproof layer is fixedly connected to the bottom of the decorative panel. Multiple sound-absorbing holes are opened on the inner wall of the sound-absorbing substrate, and micropores connect the multiple sound-absorbing holes. Two sliding grooves are opened on the left and right sides of the outer wall of the sound-absorbing substrate, and quick-installation mechanisms are provided on the inner walls of the multiple sliding grooves. The quick-installation mechanisms are used to quickly connect the sound-absorbing substrate and the secondary keel.

[0006] The above technical solution involves: secondary keels connecting to the outer walls of the main keel to enhance the stability and load-bearing capacity of the ceiling; screws at the top four corners of the secondary keels being fixed to the ceiling or other supporting structures via threaded connections to ensure stable installation and prevent structural loosening due to vibration; a sealing ring connected to the top of the sound-absorbing substrate to enhance the seal with the secondary keel, preventing sound leakage from the connection gaps, while also buffering and reducing vibration to minimize the impact on the connection points, thus solving the problem of fragile connections due to vibration in existing suspended frames; a decorative panel at the bottom of the sound-absorbing substrate to enhance the aesthetics of the ceiling and protect the substrate; and a fireproof layer at the bottom of the decorative panel to enhance the fire resistance of the ceiling and improve spatial safety. When sound reaches the sound-absorbing substrate, the sound waves enter the sound-absorbing holes. Due to the special structure of the sound-absorbing holes and micropores, the sound is constantly reflected and refracted within the holes, rubbing against the hole walls, converting sound energy into heat energy and achieving sound absorption and noise reduction.

[0007] As a further description of the above technical solution:

[0008] The quick-installation mechanism includes multiple sliding rods, each sliding rod being slidably connected to the inner wall of a corresponding slide groove. A pressure plate is fixedly connected to the far end of each sliding rod, and a spring is fixedly connected to an adjacent side of each pressure plate. An adjacent end of each spring is fixedly connected to a corresponding slide groove. An adjacent end of each sliding rod passes through the sound-absorbing substrate and is fixedly connected to a locking block. Two locking slots are formed on the left and right sides of the inner wall of the secondary keel, and the locking blocks engage with their respective locking slots.

[0009] Through the above technical solution: multiple sliding rods slide on the inner wall of corresponding sliding grooves, the sliding grooves provide precise sliding tracks for the sliding rods, limiting the movement of the sliding rods in a specified direction, and the ends of the sliding rods that are far apart are fixedly connected to pressure plates. The pressure plates provide a point of force for operation. When installing the sound-absorbing substrate, pressing the pressure plates pushes the sliding rods to slide in the sliding grooves. One end of the spring is connected to the pressure plate, and the other end is fixed to the sliding groove. Pressing the pressure plate compresses the spring, storing elastic potential energy. Releasing the pressure plate releases the elastic potential energy, pushing the pressure plate and the sliding rods back to their original positions. The adjacent end of the sliding rod passes through the sound-absorbing substrate and is connected to a locking block. The locking block cooperates with the locking slots opened on the left and right sides of the inner wall of the secondary keel. During installation, the sliding rod moves as it presses the pressure plate, and the locking block moves accordingly. When the sound-absorbing substrate and the secondary keel are accurately aligned, releasing the pressure plate resets the spring, causing the locking block to engage with the corresponding locking slot, thus firmly fixing the sound-absorbing substrate to the secondary keel. This achieves a quick and stable connection between the sound-absorbing substrate and the secondary keel, improving installation efficiency and ensuring the stability of the ceiling structure.

[0010] As a further description of the above technical solution:

[0011] Positioning rods are fixedly connected to the top four sides of the sound-absorbing substrate, and positioning grooves are opened on the bottom four sides of the secondary keel. The multiple positioning rods are slidably connected to the corresponding positioning grooves.

[0012] Through the above technical solution: the positioning rod and the positioning grooves opened around the bottom of the secondary keel form a sliding connection structure. When the sound-absorbing substrate is installed, the positioning rod can slide precisely into the positioning groove, which enables the sound-absorbing substrate and the secondary keel to be quickly and accurately aligned.

[0013] As a further description of the above technical solution:

[0014] Each of the screws has a cross-shaped groove at its bottom, and the surface of each cross-shaped groove is smoothed.

[0015] The above technical solution involves smoothing the surface of the Phillips head slot, which allows for smooth contact between the Phillips head screwdriver and the slot, reduces operating friction, and makes it easier to apply force when tightening the screw.

[0016] As a further description of the above technical solution:

[0017] A rubber pad is fixedly connected to the top of the secondary keel, and the tips of the multiple screws all penetrate the rubber pad.

[0018] Through the above technical solution: during the screw tightening process, the rubber pad can buffer the impact force generated, effectively preventing the secondary keel from being damaged due to excessive force, and the rubber pad can fill the tiny gap between the installation surface and the secondary keel, enhancing the structural sealing and preventing dust from entering the ceiling.

[0019] As a further description of the above technical solution:

[0020] The sound-absorbing substrate has multiple transverse reinforcing ribs fixedly connected to its top front and rear sides, and multiple longitudinal reinforcing ribs fixedly connected to its top left and right sides, with each of the transverse reinforcing ribs being fixedly connected to the longitudinal reinforcing ribs.

[0021] Through the above technical solution, the horizontal and vertical reinforcing ribs are combined to build a stable support frame, enhance the overall strength of the sound-absorbing substrate, improve its load-bearing capacity, and ensure that the sound-absorbing substrate is more robust and durable in use.

[0022] As a further description of the above technical solution:

[0023] Two pressing holes are provided on the left and right sides of the outer wall of the decorative panel, and the inner walls of the two pressing holes are threaded with plugs.

[0024] The above technical solution allows for convenient pressing of the pressure plate, while the blockage function seals the pressing hole, thus maintaining the integrity and aesthetics of the decorative panel while effectively preventing dust and debris from entering the ceiling.

[0025] As a further description of the above technical solution:

[0026] Each of the multiple blockages has a cross handle fixedly connected to its inner wall, and the surfaces of the multiple cross handles are treated with anti-slip coating.

[0027] Through the above technical solution, the surface of the cross handle is treated with anti-slip material, which facilitates the disassembly and installation of the blockage and enhances the ease of use.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the upper support structure is fixed with screws to enhance stability and load-bearing capacity, avoid structural loosening due to vibration, and improve the problem of existing hanging frames being prone to loosening due to vibration. The top sealing ring of the sound-absorbing substrate enhances the sealing performance with the secondary keel, buffers and reduces vibration, prevents sound leakage, and reduces the impact of vibration on the connection parts. The sound-absorbing holes and micropores work together to consume sound energy to achieve sound absorption and noise reduction. The decorative panel and fireproof layer respectively improve aesthetics, enhance fire resistance, and eliminate safety hazards.

[0030] 2. In this utility model, the locking block and the locking slot cooperate with each other. Pressing the pressure plate can push the sliding rod and compress the spring, which facilitates the adjustment of the position of the sound-absorbing substrate. When the pressure plate is released, the spring returns to its original position and drives the locking block into the locking slot, realizing a quick and firm connection between the sound-absorbing substrate and the secondary keel. This not only simplifies the installation process and improves the installation efficiency, but also ensures a stable connection and avoids the loosening problems that may be caused by conventional installation methods, thus ensuring the stability and safety of the ceiling structure.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a sound-absorbing and environmentally friendly ceiling structure, including a main keel 1, which serves as the main supporting component of the entire ceiling structure, providing a stable foundation support for the entire system. The outer walls of the main keel 1 are fixedly connected to the same secondary keel 3, further enhancing the stability and load-bearing capacity of the ceiling structure. Screws 4 are threaded to the four corners of the top of the secondary keel 3, allowing the secondary keel 3 to be firmly fixed to the ceiling or other upper supporting structures, ensuring the stable installation of the entire ceiling structure. A sound-absorbing substrate 5 is provided at the bottom of the secondary keel 3, a key component for achieving sound absorption, bearing the important responsibility of sound absorption. A sealing ring 8 is fixedly connected to the top of the sound-absorbing substrate 5, enhancing the sealing between the sound-absorbing substrate 5 and the secondary keel 3, preventing sound leakage from the connection gaps. A decorative panel 6 is fixedly connected to the bottom of the outer wall, which provides a certain degree of protection for the sound-absorbing substrate 5. A fireproof layer 7 is fixedly connected to the bottom of the decorative panel 6, which enhances the fire resistance of the ceiling and improves the safety of the entire space. Multiple sound-absorbing holes 9 are opened on the inner wall of the sound-absorbing substrate 5 to provide a channel for sound to enter the interior of the sound-absorbing substrate 5. Micropores 10 are connected between the multiple sound-absorbing holes 9, which together with the sound-absorbing holes 9 form a special structure, so that the sound is continuously reflected and refracted in the holes and rubs against the hole wall, thereby consuming sound energy and achieving the effect of sound absorption and noise reduction. Two sliding grooves 11 are opened on the left and right sides of the outer wall of the sound-absorbing substrate 5 to provide an installation position and sliding track for the quick-installation mechanism 2, so that the quick-installation mechanism 2 can play its role. The quick-installation mechanism 2 is set on the inner wall of the multiple sliding grooves 11. The quick-installation mechanism 2 is used to quickly connect the sound-absorbing substrate 5 and the secondary keel 3.

[0042] Specifically, the main keel 1, as the main supporting component of the entire ceiling structure, provides a stable foundation for the entire system. The secondary keels 3, fixedly connected to the outer walls of the main keel 1, further enhance the stability and load-bearing capacity of the ceiling structure. Screws 4, threaded at the four corners of the top of the secondary keels 3, securely fix the secondary keels 3 to the ceiling or other supporting structures above, ensuring the stability of the entire ceiling structure and preventing loosening due to vibration or other factors. The sound-absorbing substrate 5 is a key component for achieving sound absorption. The sealing ring 8, fixedly connected to the top of the sound-absorbing substrate 5, enhances the seal between the sound-absorbing substrate 5 and the secondary keels 3, preventing sound leakage from the connection gaps. On the other hand, it also acts as a buffer and shock absorber to a certain extent, reducing the impact of vibration on structural connections and avoiding problems such as the weakening of connections due to vibration in existing technologies. The decorative panel 6 not only enhances the aesthetics of the ceiling but also provides some protection for the sound-absorbing substrate 5. The fireproof layer 7 fixedly connected to the bottom of the decorative panel 6 enhances the fire resistance of the ceiling, improving the safety of the entire space. When sound travels to the sound-absorbing substrate 5, the sound waves enter the sound-absorbing holes 9. Due to the special structure of the sound-absorbing holes 9 and the micropores 10, the sound is constantly reflected and refracted within the holes, rubbing against the hole walls. The sound energy is gradually converted into heat energy and consumed, thus achieving the effect of sound absorption and noise reduction.

[0043] Reference Figure 1 , Figure 6 and Figure 7 The quick-release mechanism 2 includes multiple slide rods 201, which are slidably connected to the inner walls of corresponding slide grooves 11, providing a component foundation for the sliding connection of the quick-release mechanism 2. Each slide rod 201 has a pressure plate 202 fixedly connected to its opposite end, providing an operating point for the operator to easily manipulate the slide rods 201. Each pressure plate 202 has a spring 203 fixedly connected to an adjacent side, serving as an elastic element to provide a reset force for the quick-release mechanism 2, allowing it to return to its initial or set position after operation. The adjacent ends of the multiple springs 203 are respectively connected to… The corresponding slide groove 11 is fixedly connected, and the spring 203 is connected to the slide groove 11 to ensure the stability of the spring 203 during operation. The adjacent ends of multiple slide rods 201 all pass through the sound-absorbing substrate 5 and are fixedly connected with the locking block 204. Through the drive of the slide rod 201, the locking and separation with the locking groove 205 are realized. Two locking grooves 205 are opened on the left and right sides of the inner wall of the secondary keel 3. Multiple locking blocks 204 are respectively locked with the corresponding locking grooves 205. The locking grooves 205 and the locking blocks 204 cooperate with each other to provide a positioning and locking structure for the connection between the sound-absorbing substrate 5 and the secondary keel 3, ensuring that the connection between the two is stable.

[0044] Specifically, multiple sliding rods 201 slide on the inner wall of their respective sliding grooves 11. The sliding grooves 11 provide precise sliding tracks for the sliding rods 201, allowing them to move in a specified direction. The sliding rods 201 are located away from the pressure plate 202, which is fixedly connected at one end, providing a point of leverage for operation. When the sound-absorbing substrate 5 needs to be installed, pressing the pressure plate 202 can push the sliding rods 201 to slide within the sliding grooves 11. One end of the spring 203 is connected to the pressure plate 202, and the other end is fixed to the sliding groove 11. When the pressure plate 202 is pressed, the spring 203 is compressed and stores elastic potential energy. When the pressure plate 202 is released, the spring 203... 3. Release the elastic potential energy to push the pressure plate 202 and the slide bar 201 to reset. The adjacent end of the slide bar 201 passes through the sound-absorbing substrate 5 and is fixedly connected to the locking block 204, which cooperates with the locking grooves 205 opened on the left and right sides of the inner wall of the secondary keel 3 to realize the quick connection between the sound-absorbing substrate 5 and the secondary keel 3. During the installation process, when the slide bar 201 moves due to pressing the pressure plate 202, the locking block 204 moves accordingly. When the sound-absorbing substrate 5 and the secondary keel 3 are accurately aligned, the pressure plate 202 is released, the spring 203 is reset, and the locking block 204 is driven to be locked into the corresponding locking groove 205, thereby firmly fixing the sound-absorbing substrate 5 on the secondary keel 3.

[0045] Reference Figure 1 , Figure 2 and Figure 5 Positioning rods 12 are fixedly connected to the top four sides of the sound-absorbing substrate 5, and positioning grooves 13 are opened on the bottom four sides of the secondary keel 3. Multiple positioning rods 12 are slidably connected to the corresponding positioning grooves 13. The positioning rods 12 are used to cooperate with the positioning grooves 13 at the bottom of the secondary keel 3 to provide a positioning reference for the installation of the sound-absorbing substrate 5. Multiple screws 4 have cross grooves 14 at the bottom to provide an adaptation structure for operating the screws 4 with a cross screwdriver, making it convenient for operators to tighten or loosen the screws 4. The surfaces of multiple cross grooves 14 are all smoothed. A rubber pad 15 is fixedly connected to the top of the secondary keel 3. It is elastic and can buffer the impact force generated when the screws 4 are tightened. The tops of multiple screws 4 penetrate the rubber pad 15.

[0046] Specifically, the positioning rod 12 is slidably connected to the positioning grooves 13 opened around the bottom of the secondary keel 3. When installing the sound-absorbing substrate 5, the positioning rod 12 can slide accurately into the positioning grooves 13, ensuring that the sound-absorbing substrate 5 and the secondary keel 3 are quickly and accurately aligned, avoiding positional deviations during installation and improving installation efficiency. The surface of the cross groove 14 is smoothed. The smooth cross groove 14 allows for smoother contact between the cross screwdriver and the cross screwdriver, reducing friction during operation. When using a cross screwdriver to tighten the screw 4, it is easier to apply force. The rubber pad 15 has a certain elasticity. On the one hand, it can buffer the impact force generated when the screw 4 is tightened, preventing the secondary keel 3 from being damaged due to excessive force. On the other hand, the rubber pad 15 can fill the small gaps between the installation surface and the secondary keel 3, enhancing the sealing performance, preventing dust from entering the ceiling, affecting structural performance, and extending the service life of the ceiling.

[0047] Reference Figure 1 , Figure 2 and Figure 4 Multiple transverse reinforcing ribs 16 are fixedly connected to the front and rear sides of the top of the sound-absorbing substrate 5. The transverse reinforcing ribs 16 can enhance the strength of the sound-absorbing substrate 5 in the front-rear direction and improve its resistance to deformation. Multiple longitudinal reinforcing ribs 17 are fixedly connected to the left and right sides of the top of the sound-absorbing substrate 5, which strengthens the structural strength of the sound-absorbing substrate 5 in the left and right directions and makes the sound-absorbing substrate 5 more stable. The multiple transverse reinforcing ribs 16 are fixedly connected to the multiple longitudinal reinforcing ribs 17. Two pressing holes 18 are opened on the left and right sides of the outer wall of the decorative panel 6. The inner wall of the two pressing holes 18 is threaded with plugs 19. The pressing holes 18 facilitate pressing the pressing plate 202. The plugs 19 close the pressing holes 18, maintain the integrity and aesthetics of the appearance of the decorative panel 6, and prevent dust and debris from entering the ceiling. The inner wall of the multiple plugs 19 is fixedly connected with cross handles 20. The surface of the multiple cross handles 20 is treated with anti-slip treatment, which provides convenience for disassembling and installing the plugs 19.

[0048] Specifically, the transverse reinforcing ribs 16 and longitudinal reinforcing ribs 17 together form a stable support frame, enhancing the overall strength and load-bearing capacity of the sound-absorbing substrate 5. The pressing hole 18 facilitates pressing the pressure plate 202, and the plug 19 seals the pressing hole 18, maintaining the integrity and aesthetics of the decorative panel 6, while preventing dust and debris from entering the ceiling. The surface of the cross handle 20 is treated with anti-slip material, providing convenience for disassembling and installing the plug 19.

[0049] Working principle: The main keel 1 serves as the core support for the entire ceiling, laying a solid foundation for the entire system. The secondary keels 3, fixed around its outer perimeter, further enhance structural stability and load-bearing capacity. By using screws 4 at the four corners of the top of the secondary keels 3, they are firmly fixed to the ceiling and other supporting structures, ensuring stable installation and preventing structural loosening due to vibration. The sealing ring 8 on the top of the sound-absorbing substrate 5 not only enhances the seal between it and the secondary keel 3, preventing sound leakage from the connection gaps, but also buffers and reduces vibration, minimizing the impact of vibration on the connection points. This avoids the problem of weak connections due to vibration, as seen in traditional suspended frames, where sound can easily penetrate the sound-absorbing substrate. When the sound-absorbing substrate 5 is in place, the noise reduction process officially begins. Sound waves enter the sound-absorbing holes 9 opened on the inner wall of the sound-absorbing substrate 5. The sound-absorbing holes 9 and the interconnected micropores 10 form a special structure. Within this structure, sound is constantly reflected and refracted, and frequently rubs against the hole walls. During this process, sound energy is gradually converted into heat energy and consumed, thereby achieving sound absorption and noise reduction. The decorative panel 6 is located at the bottom of the sound-absorbing substrate 5. While enhancing the aesthetics of the ceiling, it also provides protection for the sound-absorbing substrate 5. The fireproof layer 7 fixedly connected to the bottom of the decorative panel 6 enhances the fireproof performance of the ceiling, adds a guarantee for the safety of the entire space, and maintains a stable working environment throughout the noise reduction process.

[0050] Furthermore, when the sound-absorbing substrate 5 needs to be installed, pressing the pressure plate 202 pushes the slide rod 201 to slide within the slide groove 11. One end of the spring 203 is connected to the pressure plate 202, and the other end is fixed to the slide groove 11. When the pressure plate 202 is pressed, the spring 203 is compressed and stores elastic potential energy. When the pressure plate 202 is released, the spring 203 releases its elastic potential energy, pushing the pressure plate 202 and the slide rod 201 back to their original positions. The adjacent end of the slide rod 201 passes through the sound-absorbing substrate 5 and is fixedly connected to the clip. Block 204 cooperates with the slots 205 opened on the left and right sides of the inner wall of the secondary keel 3 to realize the quick connection between the sound-absorbing substrate 5 and the secondary keel 3. During the installation process, when the slide bar 201 moves due to pressing the pressure plate 202, the block 204 moves accordingly. When the sound-absorbing substrate 5 and the secondary keel 3 are accurately aligned, the pressure plate 202 is released, the spring 203 returns to its original position, and the block 204 is driven to snap into the corresponding slot 205, thereby firmly fixing the sound-absorbing substrate 5 on the secondary keel 3.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
