Description

Technical Field

[0001] This utility model relates to the field of wall panel technology, specifically to a fire-retardant and sound-insulating wall panel for green housing construction. Background Technology

[0002] Wall panel structures are load-bearing building structures consisting of walls and floors. The walls serve as both load-bearing components and room partitions. They are the most commonly used and economical structural form in residential buildings. The disadvantage is that the interior layout is less flexible. To overcome this disadvantage, the trend is towards larger open spaces. Wall panel structures are mostly used in residences and apartments, but can also be used in public buildings such as office buildings and schools.

[0003] According to the search, CN218205197U discloses a fire-retardant and sound-insulating wall panel for green housing construction, including a wall panel body. One side of the inner wall of the wall panel body is provided with a heat insulation layer, and one side surface of the heat insulation layer is provided with sound insulation cotton. One side surface of the sound insulation cotton is provided with a sound-absorbing board, and the sound-absorbing board is provided with sound-absorbing holes. One side surface of the sound-absorbing board is provided with a reinforcing layer, and the interior of the reinforcing layer is provided with reinforcing columns. One side surface of the reinforcing layer is provided with a fire-retardant layer.

[0004] The aforementioned utility model, through the setting of sound-absorbing panels, sound-absorbing holes, and sound-insulating cotton, can effectively absorb external noise, improve the sound insulation effect of the wall panel body, and reduce noise pollution. However, the wall panel directly and rigidly contacts the wall, causing sound waves to be transmitted through "sound bridges," thereby reducing the sound insulation effect. At the same time, during the installation process, because the length of the connecting plate exceeds the wall panel body, the splicing of each wall panel directly causes misalignment and gaps due to deviation, requiring other materials for repair, which increases the installation difficulty and reduces the structural stability.

[0005] Therefore, it is of great importance to design a fire-retardant and sound-insulating wall panel for green housing construction to solve the above-mentioned defects. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model designs a fire-retardant and sound-insulating wall panel for green housing construction. This wall panel aims to solve the technical problems of reduced sound insulation effect, increased installation difficulty, and reduced structural stability under existing technologies.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fire-retardant and sound-insulating wall panel for green housing construction includes a wall panel body. The upper and lower ends of the back of the wall panel body are provided with mounting keels. Vibration damping mechanisms are installed at the four corners of the wall panel body. A splicing groove is opened on the right side of the wall panel body. A splicing strip adapted to the splicing groove is fixedly connected to the left side of the wall panel body. Fixed slots are opened on both the left and right sides of the wall panel body. Fixed inserts are inserted into the inner side of the fixed slots.

[0009] The vibration damping mechanism includes a movable rod fixedly installed on the mounting keel. A movable sleeve is slidably connected to the outer side of the movable rod. A buffer spring is sleeved on the outer side of the movable rod and on one side of the movable sleeve. A transmission rod is rotatably connected to the outer side of the movable sleeve. A connector is rotatably connected to the front end of the transmission rod. The connector is fixedly connected to the back of the wall panel body by a first mounting screw. A damper is fixedly installed between the connector and the mounting keel.

[0010] As a preferred embodiment of this utility model, one end of the movable rod and the damper are both fixedly connected to a mounting foot, and both sets of mounting feet are fixedly connected to the mounting keel by a second mounting screw. A rubber pad is fixedly connected to the connection between the connector and the wall panel body.

[0011] As a preferred embodiment of this utility model, the interior of the wall panel body is provided with a reinforcing layer, a flame-retardant layer, a sound insulation and noise reduction layer and a heat insulation layer in sequence from front to back.

[0012] As a preferred embodiment of this utility model, the reinforcing layer is composed of multiple sets of hexagonal holes, and the multiple sets of hexagonal holes are evenly distributed inside the wall panel body.

[0013] As a preferred embodiment of this utility model, the flame-retardant layer is composed of fire-retardant aerogel, and the heat insulation layer is made of polyester fiber.

[0014] As a preferred embodiment of this utility model, the sound insulation and noise reduction layer is composed of a waveform noise reduction plate and sound insulation cotton, and the waveform noise reduction plate has multiple sets of sound absorption holes inside.

[0015] As a preferred embodiment of this utility model, both the left and right ends of the fixing strip are fixedly connected with elastic tightening edges, and the top end of the fixing strip is provided with a disassembly hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, by designing the sound insulation and noise reduction layer inside the wall panel body, the geometric shape of the waveform noise reduction board is used to change the sound wave propagation path, forcing the sound wave to undergo multiple reflections and interferences at the waveform interface. At the same time, the sound absorption holes inside achieve active sound absorption, and together with the sound insulation cotton, the noise is dissipated in segments, thereby improving the sound insulation and noise reduction effect.

[0018] 2. In this utility model, the installation keel and vibration damping mechanism are designed in conjunction. After the installation keel is installed on the wall, the movable rod is then installed and fixed on the installation keel. The connector is installed and fixed to the wall panel body through the first installation screw, so that a sound insulation cavity is formed between the wall panel body and the installation keel. This sound insulation cavity can block the transmission of sound bridge. At the same time, after the wall panel body is installed, the movable sleeve can slide on the outside of the movable rod, causing the buffer spring to deform accordingly. In conjunction with the damper, the rebound impact of the buffer spring is suppressed to ensure stability. Thus, the mechanical vibration energy can be converted into heat energy and attenuated, effectively suppressing the direct transmission of solid sound. In addition, the sound insulation cavity greatly improves the sound insulation and noise reduction effect.

[0019] 3. In this utility model, through the cooperative design of splicing groove, splicing strip, fixing slot and fixing insert, when splicing and installing the wall panel bodies, the splicing strip is aligned with the inside of the splicing groove for quick and easy alignment and installation, so that the fixing slots between the two wall panel bodies are aligned accordingly. Then the fixing insert is inserted into the inside of the fixing slot. The elastic tight edge can ensure the tightness of the fixing insert after insertion, thus facilitating splicing and installation while ensuring the connection stability after installation. Moreover, the fixing insert can be easily pulled out for disassembly through the disassembly hole. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A fire-retardant and sound-insulating wall panel for green housing construction includes a wall panel body 1. The upper and lower ends of the back of the wall panel body 1 are provided with mounting keels 2. Vibration damping mechanisms 3 are installed at the four corners of the wall panel body 1. A splicing groove 4 is opened on the right side of the wall panel body 1. A splicing strip 5 adapted to the splicing groove 4 is fixedly connected to the left side of the wall panel body 1. Fixed slots 6 are opened on both the left and right sides of the wall panel body 1. Fixed inserts 7 are inserted into the inner side of the fixed slots 6.

[0028] First, in this implementation, the specific structure of the vibration damping mechanism 3 is as follows:

[0029] The vibration damping mechanism 3 includes a movable rod 301 fixedly installed on the mounting keel 2. A movable sleeve 302 is slidably connected to the outer side of the movable rod 301. A buffer spring 303 is sleeved on the outer side of the movable rod 301 and on one side of the movable sleeve 302. A transmission rod 304 is rotatably connected to the outer side of the movable sleeve 302. A connector 305 is rotatably connected to the front end of the transmission rod 304. The connector 305 is fixedly connected to the back of the wall panel body 1 by a first mounting screw 306. A damper 307 is fixedly installed between the connector 305 and the mounting keel 2. After the mounting keel 2 is installed on the wall, the movable rod 301 is then installed and fixed on the mounting keel 2. The wall panel is mounted on the keel 2, and the connector 305 is fixed to the wall panel body 1 by the first mounting screw 306, so that a sound insulation cavity is formed between the wall panel body 1 and the mounting keel 2. This sound insulation cavity can block the transmission of sound bridge. At the same time, after the wall panel body 1 is installed, the movable sleeve 302 can slide on the outside of the movable rod 301, causing the buffer spring 303 to deform accordingly. In conjunction with the damper 307, the rebound impact of the buffer spring 303 is suppressed to ensure stability. Thus, the mechanical vibration energy can be converted into heat energy and attenuated, effectively suppressing the direct transmission of solid sound. In addition, the sound insulation cavity greatly improves the sound insulation and noise reduction effect.

[0030] Furthermore, one end of the movable rod 301 and the damper 307 are both fixedly connected to mounting feet 308. Both sets of mounting feet 308 are fixedly connected to the mounting keel 2 by second mounting screws 309. A rubber pad 310 is fixedly connected to the connection between the connector 305 and the wall panel body 1. The mounting feet 308 are fixed to the mounting keel 2 by the second mounting screws 309, thereby installing and fixing the movable rod 301 and the damper 307. At the same time, the rubber pad 310 between the connector 305 and the wall panel body 1 avoids damage to the surface of the wall panel body 1 due to installation. At the same time, the deformation of the rubber pad 310 itself can also dissipate vibration, further improving the noise reduction effect.

[0031] Then, the interior of the wall panel body 1 is provided with a reinforcing layer 101, a flame-retardant layer 102, a sound insulation and noise reduction layer 103 and a heat insulation layer 104 in sequence from front to back. The reinforcing layer 101 is composed of multiple sets of hexagonal holes 105, and the multiple sets of hexagonal holes 105 are evenly distributed inside the wall panel body 1. The reinforcing layer 101 composed of multiple sets of hexagonal holes 105 reduces the weight of the wall panel body 1 while ensuring the structural strength of the wall panel body 1.

[0032] Furthermore, the flame-retardant layer 102 is composed of fire-retardant aerogel, and the heat insulation layer 104 is made of polyester fiber. The flame-retardant layer 102, composed of fire-retardant aerogel, can withstand temperatures above 800°C without decomposing. By forming a dense carbonized layer, it isolates oxygen and prevents the spread of flames. Combined with the heat insulation layer 104 made of polyester fiber, it provides excellent flame-retardant and heat insulation effects, thereby improving the safety of the wall panel body 1. At the same time, polyester fiber is non-toxic and harmless, meets green building material standards, and avoids the release of harmful substances such as formaldehyde.

[0033] Secondly, the sound insulation and noise reduction layer 103 is composed of a waveform noise reduction plate 106 and a sound insulation cotton 107. The waveform noise reduction plate 106 has multiple sets of sound absorption holes 108 inside. By using the geometric shape of the waveform noise reduction plate 106 itself to change the propagation path of the sound wave, the sound wave is forced to undergo multiple reflections and interferences at the waveform interface. At the same time, the sound absorption holes 108 inside it achieve active sound absorption. Together with the sound insulation cotton 107, the noise is dissipated in segments, thereby improving the sound insulation and noise reduction effect.

[0034] Finally, both ends of the fixing strip 7 are fixedly connected with elastic fastening edges 701, and the top of the fixing strip 7 is provided with a disassembly hole 702. When splicing and installing the wall panel bodies 1, the splicing strip 5 is aligned with the inside of the splicing groove 4 for quick and easy alignment and installation, so that the fixing slots 6 between the two wall panel bodies 1 are aligned accordingly. Then, the fixing strip 7 is inserted into the inside of the fixing slot 6. The elastic fastening edges 701 can ensure the tightness of the fixing strip 7 after insertion, thus facilitating splicing and installation while ensuring the connection stability after installation. Moreover, the fixing strip 7 can be easily pulled out for disassembly through the disassembly hole 702.

[0035] In this embodiment, the specific implementation scenario is as follows: After the mounting keel 2 is installed on the wall, the movable rod 301 is then installed and fixed on the mounting keel 2. The connector 305 is installed and fixed to the wall panel body 1 through the first mounting screw 306, so that a sound insulation cavity is formed between the wall panel body 1 and the mounting keel 2. This sound insulation cavity can block the transmission of sound bridge. At the same time, after the wall panel body 1 is installed, the movable sleeve 302 can slide on the outside of the movable rod 301, causing the buffer spring 303 to deform accordingly. In conjunction with the damper 307, the rebound impact of the buffer spring 303 is suppressed to ensure stability. Thus, the mechanical vibration energy can be converted into heat energy and attenuated. The waveform noise reduction plate 106 changes the sound wave propagation path by its own geometric shape, forcing the sound... The wave undergoes multiple reflections and interferences at the waveform interface, while the sound-absorbing holes 108 inside achieve active sound absorption. Combined with the sound insulation cotton 107, it achieves segmented noise dissipation. When splicing and installing the wall panel bodies 1, the splicing strip 5 is aligned with the inside of the splicing groove 4 for quick and easy installation, so that the fixing slots 6 between the two wall panel bodies 1 are aligned accordingly. Then, the fixing strip 7 is inserted into the inside of the fixing slot 6. The elastic tight-fitting edge 701 can ensure the tightness of the fixing strip 7 after insertion. The whole operation process is simple and convenient. This utility model can effectively suppress the direct transmission of solid sound through design, achieve segmented noise dissipation, greatly improve the sound insulation and noise reduction effect, and at the same time facilitate splicing and installation while ensuring the connection stability after installation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
