Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a high-standard soundproof light steel keel partition wall. Background Technology

[0002] Modern architecture has significantly increased its requirements for "sound privacy." For example, hotel rooms need to avoid noise from corridors and conversations in adjacent rooms, while hospital wards need to isolate equipment noise and the sound of people walking around. Traditional partition walls rely on on-site wet construction, which has problems such as long construction period, high labor costs, and a lot of construction waste. This is seriously inconsistent with the trend of "prefabricated and quick-installation" in modern architecture. As a result, a high-standard soundproof light steel keel partition wall has emerged. In the panel design of high-standard soundproof light steel keel partition walls, the conventional solution replaces the traditional single-layer thin board with "double or multi-layer high-density panel stacking" to enhance the "mass law" effect. For example, double-layer fire-resistant gypsum board or damping soundproof gypsum board is used. By increasing the surface density of the material, the direct transmission of mid-to-high frequency airborne sound is blocked. Compared with single-layer thin board, the sound insulation effect is greatly improved. For scenarios with higher sound insulation requirements such as recording studios and hotel rooms, metal sound insulation felt is further added between the panel layers. This type of damping material can convert the panel vibration energy caused by sound waves into a small amount of heat energy consumption through the internal friction effect, effectively suppressing the coincidence effect of the panel, further weakening the penetration ability of mid-to-high frequency sound waves, and ensuring the privacy and quietness of the sound environment. The current high-standard soundproof light steel keel partition wall, with its core advantages of being thin, having high sound insulation, and being prefabricated, not only effectively solves the pain points of traditional partition walls being large in size and slow in construction, but also promotes the upgrading of building acoustics technology towards high efficiency and modularity. It provides solutions that meet high sound insulation standards for residential, hotel, hospital and other scenarios, and plays a significant positive role in promoting the functional iteration and acoustic performance improvement of the building interior industry. However, in some current construction schemes, the main structure of the partition wall (such as exposed sound insulation felt or filling cotton) is directly exposed, which poses obvious safety hazards. The exposed filling material can cause its fibers to fall off and disperse, which may cause respiratory irritation if inhaled. In addition, the exposed filling material can be damaged by accidental contact, thereby reducing the service life of the partition wall. Therefore, a high-standard soundproof light steel keel partition wall is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a high-standard soundproof light steel keel partition wall, which aims to improve the problem that the exposed filler in the existing technology can be damaged by accidental contact, thereby reducing the service life of the partition wall.

The sound insulation mechanism includes multiple sound insulation cotton boards, four of which are slidably connected to the bottom of the ground joist outer wall. Plasterboard is placed on both sides of each sound insulation cotton board. Spring pads are fixedly connected to the far side of two plasterboards. A protective plate is fixedly connected to the other side of the spring pads. A reinforcing component is fixedly connected to the inner wall of the protective plate.

As a further description of the above technical solution: The reinforcing component includes a flame-retardant layer, one side of which is fixedly connected to the inner wall of the protective plate, and the other side of which is fixedly connected to a heat-resistant layer. A waterproof layer is fixedly connected to the side of the heat-resistant layer away from the flame-retardant layer, and multiple anti-crack grooves are provided on the side of the protective plate away from the spring pad.

[0005] This utility model has the following beneficial effects: 1. In this utility model, sound insulation cotton board is used as the core acoustic component. Its porous structure absorbs sound wave energy, laying the foundation for the sound insulation capability of the partition wall. The gypsum board enhances the sound wave blocking effect through its high surface density. Together with the sound insulation cotton board, they form a synergistic absorption and blocking effect, significantly improving the overall sound insulation. The sealant fills the gaps between the layers of materials, eliminating sound wave leakage channels and further strengthening the integrity of the sound insulation. The elastic pad, through its elastic deformation, forms a buffer when external forces are transmitted to the protective board, preventing damage to the gypsum board and sound insulation cotton board due to direct compression, effectively extending the life of the core component. The protective board and the elastic pad work together to form a physical barrier, preventing internal materials from getting damp or leaking out. From the perspective of structural protection, this indirectly extends the overall service life of the partition wall, ultimately achieving a dual guarantee of sound insulation performance and durability.

[0006] 2. In this utility model, the heat-resistant layer enables the protective board to withstand high temperatures. Its special material can delay the transmission of high temperatures to the interior, protecting core components such as gypsum board and sound insulation cotton board from heat damage. The flame-retardant layer prevents the spread of flames and improves fire safety through the dual effects of expansion carbonization and chemical inhibition. The waterproof layer blocks water vapor with its dense structure, preventing internal materials from becoming damp and failing. The crack-resistant groove disperses stress, allowing the protective board to withstand greater external forces and reducing cracking, thereby extending the overall service life of the partition wall and ensuring the stability of the sound insulation system.

[0009] 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.

[0010] Example: A high-standard soundproof light steel keel partition wall, referring to Figures 1 to 3 The system includes a ground joist 1, which serves as the base of the partition wall, fixing it to the ground and ensuring the stability of the entire partition wall structure. It is the starting component for frame construction. The outer wall of the ground joist 1 is slidably connected to a skeleton mechanism 2, which forms the main frame of the partition wall and ensures the stability of the partition wall structure. The outer wall of the ground joist 1 is also slidably connected to a sound insulation mechanism 3, which is filled inside the skeleton mechanism 2. Through a multi-layer structure, it blocks sound transmission and achieves a high standard of sound insulation. The inner wall of the skeleton mechanism 2 is threaded with multiple screws 4, which tightly connect the various components of the skeleton mechanism 2 to prevent the frame from loosening, enhance the stability of the overall structure, and ensure that the partition wall is not easily deformed during long-term use. Specifically, the ground joists 1 serve as the foundation of the partition wall. By fixing them to the ground, they form a stable support and provide the initial installation benchmark for the entire partition wall structure. Their levelness directly determines the verticality of the frame and is the core starting point for ensuring overall stability. The skeleton mechanism 2, which is slidably connected to the outer wall of the ground joists 1, forms the main frame through the nesting and snapping between the joists. It utilizes the rigidity of light steel materials to distribute the load and form an anti-deformation support system, ensuring that the partition wall is not easily shaken by external forces during long-term use. At the same time, the sound insulation mechanism 3, which is slidably connected to the ground joists 1, is precisely embedded in the cavity of the skeleton mechanism 2. Through the combination of multiple layers of sound-absorbing and sound-insulating materials, it sequentially completes reflection, absorption, and energy conversion when sound waves penetrate. It uses the principle of multi-interface barrier to block the sound transmission path. Multiple screws 4 on the inner wall of the skeleton mechanism 2 tightly lock the joist components through threaded connections, eliminating gaps to avoid the formation of "sound bridges". This not only enhances the overall integrity of the frame to prevent loosening but also reduces vibration and sound transmission, ultimately achieving a synergistic effect of structural stability and high-standard sound insulation. The sound insulation mechanism 3 includes multiple sound insulation cotton panels 31, four of which are slidably connected to the outer wall of the ground joist 1 at their bottom. The sound insulation cotton panels 31 have a porous structure, which can absorb sound wave energy and reduce sound penetration, making them the core component for achieving sound insulation. Multiple sound insulation cotton panels 31 can be spliced ​​together to cover the internal space of the frame, improving the uniformity of sound insulation. Plasterboard 32 is placed on both sides of the sound insulation cotton panels 31. The plasterboard 32 serves as a support and auxiliary sound insulation layer for the sound insulation cotton panels 31, further blocking sound waves and enhancing the overall strength of the sound insulation mechanism 3, preventing deformation of the sound insulation cotton panels 31. Spring pads 33 are fixedly connected to the far sides of the two plasterboard 32. The spring pads 33 are elastic, buffering external forces and further improving the sound insulation effect. On the other side, a protective plate 34 is fixedly connected. The protective plate 34 serves as the outer layer of protection for the partition wall, preventing the internal gypsum board 32 and sound insulation cotton board 31 from getting damp or damaged by external forces. At the same time, it works with the spring pad 33 to prevent material leakage and extend the service life of the sound insulation mechanism 3. The inner wall of the protective plate 34 is fixedly connected with a reinforcing component 35. The reinforcing component 35 gives the protective plate 34 high temperature resistance, flame retardancy, and waterproof properties, improving the environmental adaptability and safety of the partition wall and ensuring that the partition wall can be used stably in different scenarios. The gap between the two gypsum boards 32 and the sound insulation cotton board 31 is filled with sealant 36. The sealant 36 can seal the gap, prevent sound from penetrating through the gap, and prevent moisture from entering the internal parts and damaging them, further improving the sound insulation effect and structural durability. Specifically, the sound insulation mechanism 3 constructs an acoustic barrier through the synergistic effect of multiple layers of materials. The core sound insulation cotton board 31 uses a porous structure to capture sound waves and converts sound energy into heat energy through air friction. It splices and covers the internal space of the frame to eliminate sound insulation blind spots. The gypsum boards 32 on both sides rely on their surface density advantage to block direct sound waves and provide rigid support for the sound insulation cotton board 31 to prevent it from deforming under pressure. The elastic pads 33 on the outside of the gypsum board buffer vibration through elastic deformation, which weakens solid sound transmission and provides buffer for the outer protective board 34. The protective board 34, together with the reinforcing component 35, forms a physical barrier to block water vapor and external force erosion. The sealant 36 fills all gaps to prevent sound waves from penetrating through the gaps, achieving the dual functions of high-standard sound insulation and structural protection. The frame structure 2 includes two side keels 22, the outer walls of which are slidably connected to the outer wall of the ground keel 1. The side keels 22 are located on both sides of the partition wall. The outer wall of the ground keel 1 is slidably connected to three vertical keels 23, which are the main load-bearing components of the frame structure 2. The outer walls of the two side keels 22 and the outer walls of the three vertical keels 23 are slidably connected to the top keel 21. The top keel 21 corresponds vertically to the ground keel 1, forming the top support of the frame. Together with the side keels 22 and the vertical keels 23, it forms a complete rectangular frame, ensuring the overall structural balance of the partition wall. The inner walls of the side keels 22 and the vertical keels 23 are slidably connected to the through keel 24. The through keel 24 passes horizontally through the vertical keel 23, enhancing the lateral stability of the frame, preventing the vertical keel 23 from tilting, and providing support for the sound insulation cotton board 31. Specifically, the skeleton structure 2 constructs a rigid support system through the nested combination of multiple layers of keels. The side keels 22 are slidably connected to the ground keel 1, serving as the vertical reference for the edge of the partition wall. Together with the three vertical keels 23, they form the main load-bearing skeleton. The bending resistance of the light steel material is used to distribute the longitudinal load. The top keel 21 corresponds vertically to the ground keel 1 and forms a closed rectangular frame through the slidable connection with the side keels 22 and the vertical keels 23. The geometric stability is used to balance the overall force and prevent the partition wall from tilting. The transverse through keel 24 is embedded in the inner wall of the side keels 22 and the vertical keels 23, which not only enhances the transverse stiffness of the frame to resist lateral forces, but also provides support points for the internal sound insulation cotton board 31. This ensures that the skeleton remains stable when bearing the weight of the sound insulation mechanism 3 and external impacts, providing a structural foundation for the sound insulation function.

[0011] Reference Figure 2 and Figure 4 The reinforcing component 35 includes a flame-retardant layer 352. One side of the flame-retardant layer 352 is fixedly connected to the inner wall of the protective plate 34. The flame-retardant layer 352 can prevent the spread of flames, improve the fire safety of the partition wall, and reduce fire hazards. The other side of the flame-retardant layer 352 is fixedly connected to a heat-resistant layer 351. The heat-resistant layer 351 can withstand higher temperatures, reduce damage to the internal components of the protective plate 34 caused by high temperatures, and ensure that the partition wall can maintain structural stability and sound insulation effect in high-temperature environments. The side of the heat-resistant layer 351 away from the flame-retardant layer 352 is fixed. A waterproof layer 353 is connected, which can block water vapor penetration and prevent the gypsum board 32 and sound insulation cotton board 31 inside the protective plate 34 from getting damp and moldy, extending the service life of the sound insulation mechanism 3 and improving the applicability of the partition wall in a humid environment. Multiple anti-crack grooves 354 are opened on the side of the protective plate 34 away from the spring pad plate 33. The anti-crack grooves 354 can disperse the stress generated by external forces, prevent the protective plate 34 from cracking due to concentrated force, enhance the deformation resistance of the protective plate 34, and thus improve the durability of the entire partition wall. Specifically, the reinforced component 35 achieves improved environmental adaptability through gradient protection of multi-layer functional materials. The flame-retardant layer 352 on the inner wall of the protective plate 34 uses flame retardants to inhibit the spread of flames. Through chemical flame retardancy and physical heat insulation, it blocks the spread of fire and reduces the impact of high temperature on the internal structure. The heat-resistant layer 351 on its inner side can withstand high temperature. Through the thermal stability of high-temperature resistant materials, it slows down heat conduction and ensures that the gypsum board 32 and the sound insulation cotton board 31 maintain their shape and sound insulation performance at high temperature. The waterproof layer 353 on the other side of the heat-resistant layer 351 relies on the dense molecular structure to block water vapor penetration and avoid the sound insulation cotton board 31 from absorbing moisture and failing, and the gypsum board 32 from softening due to the humid environment. The crack-resistant groove 354 on the outer side of the protective plate 34 disperses stress and prevents the protective plate 34 from cracking due to temperature changes or external impacts. Finally, through the layered protection of fire resistance, heat resistance, moisture resistance and crack resistance, the sound insulation mechanism 3 is guaranteed to function stably in complex environments. The vertical keel 23 has an H-shaped cross-section. This H-shaped structure enhances its load-bearing capacity and bending resistance, while also providing installation space for the through keel 24 and sound insulation board 31, ensuring a tight connection between all components. The side keel 22 has a U-shaped cross-section. This U-shaped structure facilitates splicing with the ground keel 1, top keel 21, and vertical keel 23, forming a stable connection node. It also restricts the position of the sound insulation mechanism 3, preventing its displacement. The ground keel 1 has a U-shaped cross-section. This U-shaped structure accommodates the bottom of the side keel 22 and vertical keel 23, making the splicing of each keel tighter and improving the stability of the frame bottom. It also provides bottom support for the sound insulation board 31. To prevent the sound insulation panels 31 from directly contacting the ground, the top joist 21 has a U-shaped cross-section, corresponding to the bottom joist 1. This U-shaped structure accommodates the tops of the side joists 22 and vertical joists 23, ensuring a stable connection at the top of the frame. It also provides support for the top sound insulation panels 31, maintaining the integrity of the sound insulation mechanism 3. The tops of four sound insulation panels 31 are slidably connected to the bottom of the through joist 24. The through joist 24 provides intermediate support for these four sound insulation panels 31, preventing them from sagging due to their own weight and ensuring they remain flat without affecting the sound insulation effect. The through joist 24 has a U-shaped cross-section, which facilitates... The vertical keel 23 connects and provides a support surface for the sound insulation cotton board 31, ensuring that the sound insulation cotton board 31 is firmly installed and not easily moved. The bottom of four other sound insulation cotton boards 31 are slidably connected to the outer wall of the through keel 24. These four sound insulation cotton boards 31 cooperate with the through keel 24 to fill the space above the through keel 24, achieving full coverage of the sound insulation cotton boards 31 inside the frame, avoiding sound insulation dead spots, and ensuring uniform overall sound insulation effect. The outer walls of the other four sound insulation cotton boards 31 are slidably connected to the outer wall of the top keel 21. These four sound insulation cotton boards 31 fill the space below the top keel 21, and cooperate with the other sound insulation cotton boards 31 to complete the sound insulation of the entire frame. The filling ensures a sound insulation layer from top to bottom, achieving a high standard of sound insulation. The outer walls of twelve screws 4 are threaded to the inner walls of the two side keels 22. These twelve screws 4 tightly fix the side keels 22 to the ground keel 1, the top keel 21, and the vertical keel 23, preventing the side keels 22 from loosening and ensuring the stability of the frame side structure without tilting. The outer walls of eighteen screws 4 are threaded to the inner walls of the three vertical keels 23. These eighteen screws 4 fix the vertical keels 23 to the ground keel 1, the top keel 21, and the through keel 24, enhancing the load-bearing capacity and stability of the vertical keels 23 and ensuring that the vertical keels 23 can support the entire frame and sound insulation mechanism 3 for a long time. Specifically, each keel forms a collaborative support system through specific cross-sectional shapes and connection designs. The H-shaped vertical keel 23 enhances bending resistance and load-bearing capacity due to its cross-sectional moment of inertia. Its groove provides precise installation space for the through keel 24 and sound insulation cotton board 31. The U-shaped side keel 22, ground keel 1, and top keel 21 are spliced ​​together through nested grooves, ensuring tight connection of nodes and limiting the sound insulation cotton board 31 to prevent displacement. The through keel 24 is horizontally embedded into the groove of the vertical keel 23, which not only strengthens the lateral rigidity of the frame but also provides intermediate support for the upper and lower layers of sound insulation cotton board 31. Together with the top keel 21 and ground keel 1, it completes the full space coverage of the sound insulation cotton board 31. The screws 4 are fixed in groups to rigidly lock each node, eliminate gaps to block sound bridges, and ultimately achieve the unity of structural stability and efficient sound insulation material.

[0012] The implementation principle of this application embodiment is as follows: First, the ground keel 1 is installed on the site where the keel partition wall is to be built. Then, a side keel 22 is slid into the outer wall of the ground keel 1. Then, three vertical keels 23 are slid into the ground keel 22 at equal intervals. Then, another side keel 22 is slid into the ground keel 1. With the help of ten screws 4, the initial frame composed of the vertical keel 23, the side keel 22 and the ground keel 1 is fixed. Next, the through keel 24 is slid into the inner wall of the side keel 22 and the inner wall of the vertical keel 23. Then, the vertical keel 23, the side keel 22 and the through keel 24 are firmly fixed with ten screws 4, so that the entire frame gradually takes shape. Finally, the top keel 21 is slid into the outer wall of the vertical keel 23 and the side keel 22. Then, the top keel 21, the side keel 22 and the vertical keel 23 are firmly fixed with ten screws 4, so that the entire light steel keel partition wall frame is stably formed. Thanks to the presence of the sound insulation cotton board 31, the entire partition wall has a sound insulation effect. Thanks to the presence of the gypsum board 32, the sound insulation effect of the partition wall is greatly improved. Thanks to the presence of the sealant 36, the gaps between the sound insulation cotton board 31 and the gypsum board 32, as well as between the spring pad 33 and the protective board 34, can be filled, greatly improving the sound insulation effect of the entire partition wall. Thanks to the presence of the spring pad 33, when external forces are applied to the protective board 34, the protective board 34 will first squeeze the spring pad 33 when squeezing the gypsum board 32, thus enabling the spring pad 33 to effectively protect the gypsum board 32 and the sound insulation cotton board 31, greatly extending the service life of the entire partition wall. The protective board 34 and the spring pad 33 work together to prevent the material of the gypsum board 32 and the sound insulation cotton board 31 from leaking out, thereby indirectly extending the service life of the entire partition wall. Thanks to the presence of the heat-resistant layer 351, the protective plate 34 has a high-temperature resistance effect; thanks to the presence of the flame-retardant layer 352, the protective plate 34 has a fire-preventing function; thanks to the presence of the waterproof layer 353, the protective plate 34 has a water-proof function; and thanks to the presence of the crack-resistant groove 354, the protective plate 34 can withstand greater external forces, thereby improving the service life of the entire partition wall.
