With the continuous development of the construction field, the application of assembled interior partition walls is becoming more and more widespread, gradually replacing the cement-cast interior partition walls. The construction of assembled interior partition walls improves the assembly efficiency of wall panels and saves costs compared with the casting method, and is also convenient for later disassembly and assembly.

[0003] When constructing existing interior partition walls, it is necessary to first fix the keel brackets on both side walls, the floor and the wall top. And fixing the keel brackets requires bolt fixing, which requires drilling holes in both side walls, the floor and the wall top, causing certain damage to the original side walls, the floor and the wall top, and affecting later redecoration.

[0006] Preferably, the fixing component includes a threaded rod, which is rotatably connected to the inner wall of the support member. A knob is fixedly connected to the top of the threaded rod. A moving block is threadedly connected to the surface of the threaded rod. Rotating rods are rotatably connected to the left and right sides of the moving block. Pressing blocks are rotatably connected to the opposite sides of the two rotating rods.

[0007] Preferably, sliding grooves are formed on the front and rear sides of the inner wall of the support member. Both pressing blocks slide in the adjacent two sliding grooves.

[0008] Preferably, the limiting component includes a connecting block fixedly connected between the connecting rod, a second dovetail tenon fixedly connected to the left side of the connecting block, and two sliding rods fixedly connected to the right side of the inner wall of the connecting block.

[0009] Preferably, two springs are fixedly connected to the right side of the locking member, and the right ends of the two springs are fixedly connected to the connecting block.

[0010] Preferably, the installation component includes a fixing member fixedly connected to the front wall panel. A square block is fixedly connected to the rear side of the fixing member, and a fixing plate is fixedly connected to the front side of the rear wall panel.

[0011] Preferably, a first screw is provided on the front side of the front wall panel. The rear end of the first screw penetrates and extends into the square block, and the first screw is threadedly connected to the square block. A second screw is provided on the rear side of the rear wall panel. The front end of the second screw penetrates and extends into the square block, and the second screw is threadedly connected to the square block.

[0012] Preferably, reinforcing ribs are fixedly connected to the inner walls of multiple wall panels, and the reinforcing ribs are made of fiberglass.

[0013] Preferably, the sides of the two extrusion blocks away from the rotating rod are made of rubber, and serrated patterns are provided on the sides of the two extrusion blocks away from the rotating rod.

[0014] Preferably, multiple filling blocks are made of glass wool, and sealing rubber strips are provided between adjacent wall panels.

[0015] Working principle: The user first places the support member at a suitable position in the corner. Through the first dovetail tenon on the top of the support member and the dovetail groove on the right side of the connecting member, multiple connecting members are connected to the support member to build a preliminary outer ring frame. Then, multiple connecting rods are placed between the support members for support. Next, filling blocks made of glass wool are placed between the connecting rods for sound insulation. Rotating the knob drives the threaded rod to rotate, causing the moving block to move along the threaded rod, driving the rotating rod to change the angle, and pushing the extrusion block to slide in the chute to squeeze the wall, fixing the frame by using the frictional force. When installing the connecting rod, insert the second dovetail tenon on the connecting block into the groove formed by the connection of the support member and the connecting member, and the locking member is inserted into the limiting groove under the action of the spring to prevent loosening. When installing the wall panel, first fix the fixing member, the square block and the front wall panel with the first screw. The square block is inserted into the intersection of the connecting rods. Then, fix the rear wall panel, the fixing plate and the square block with the second screw. The reinforcing ribs made of fiberglass in the wall panel enhance the strength. The rubber material and serrated patterns of the extrusion block ensure stable fixation. The sealing rubber strips between adjacent wall panels enhance sound insulation, waterproofing and moisture-proofing.

[0016] The present invention provides a prefabricated sound-insulating internal partition wall structure, which has the following beneficial effects: 1. In the present invention, by placing the support member at the corner of the wall, a plurality of connecting members and the support member are connected through the first dovetail tenon and the dovetail groove, so as to realize the rapid erection of the frame, save the erection time, and improve the construction efficiency. At this time, rotating the knob drives the threaded rod to rotate, thereby driving the moving block and the rotating rod to move. At this time, the pressing block presses the wall, so that the frame can be rapidly erected without drilling holes in the wall, avoiding damage to the wall structure and protecting the original integrity of the wall.

[0017] 2. In the present invention, a plurality of connecting members and the support member are connected through the first dovetail tenon and the dovetail groove. After the outer frame is erected, the second dovetail tenon is inserted into the joint of the first dovetail tenon and the dovetail groove, and at the same time, the locking member is inserted into the limiting groove under the action of the spring, so as to realize the rapid erection of the internal frame and fix the outer frame again to prevent shaking, simplify the construction process, and improve the overall construction efficiency.

[0018] 3. In the present invention, the front wall panel, the fixing member and the square block are fixed through the first screw. At this time, the fixing member passes through the overlapping part of the two connecting rods, and the fixing member fixes the two connecting rods. At this time, the second screw fixes the rear wall panel and the fixing plate, and realizes the fixation of the wall panel on the frame by connecting the second screw with the square block, so as to realize the rapid installation of the wall panel. At the same time, the fixing member and the square block fix the two staggered connecting rods, and perform secondary fixation on the overall frame to prevent the horizontal and vertical connecting rods from sliding and causing the structure to loosen.

[0019] 4. In the present invention, the wall panel is supported by the reinforcing ribs inside the wall panel, avoiding stress concentration in a certain local area of the wall panel, thereby effectively preventing the wall panel from cracking and breaking, enhancing the overall strength and stability of the wall panel. At the same time, the filling blocks filled in the frame effectively block the transmission of sound between different indoor spaces and reduce the noise interference between adjacent spaces.

Detailed implementation manners

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1 - attached Figure 3 , the embodiment of the present invention provides an assembled sound-insulating interior partition wall structure, including a plurality of support members 3. A plurality of connecting members 4 are arranged between the plurality of support members 3. First dovetail tenons 13 are fixedly connected to the tops of the plurality of support members 3 and the left sides of the plurality of connecting members 4. Dovetail grooves 14 are provided on the right sides of the plurality of support members 3 and the right sides of the plurality of connecting members 4. A plurality of limiting grooves 15 are provided on both the left and right sides of the plurality of connecting members 4. A plurality of wall panels 1 are arranged between the front and rear sides of the plurality of support members 3. Fixing assemblies are arranged on the inner walls of the plurality of support members 3. A plurality of connecting rods 5 are arranged between the plurality of support members 3. Limiting assemblies are arranged on both sides of the plurality of connecting rods 5. Filling blocks 23 are arranged between the plurality of connecting rods 5. Installation assemblies are arranged between two adjacent wall panels 1 before and after.

[0024] Specifically, the user first places the support member 3 at a suitable position in the corner. Then, through the first dovetail tenon 13 where the top of the support member 3 is fixedly connected to the left side of multiple connecting members 4, and the dovetail grooves 14 opened on the right side of multiple support members 3 and the right side of multiple connecting members 4, the multiple connecting members 4 are connected to the support member 3 to build a preliminary outer ring frame. Moreover, the connection method of the mortise and tenon structure is convenient for operation and has a stable connection, laying a foundation for subsequent construction. Then, multiple connecting rods 5 are placed between multiple support members 3 for support. The multiple connecting rods 5 are distributed vertically and horizontally, enhancing the overall stability of the frame so that it can better withstand external forces. Rectangular grooves are opened on the surfaces of the multiple connecting rods 5, and the fixing members 6 and square blocks 20 are inserted into the rectangular grooves for fixation. After that, filling blocks 23 are placed between the multiple connecting rods 5 to achieve the sound insulation function, meet the sound insulation requirements of the internal partition wall, and improve the acoustic environment quality of the indoor space.

[0025] Refer to the attached Figure 3 and the attached Figure 4 As shown in the figure, the fixing component includes a threaded rod 9, which is rotatably connected between the inner wall of the support member 3. A knob 8 is fixedly connected to the top of the threaded rod 9. A moving block 10 is threadedly connected to the surface of the threaded rod 9. Rotating rods 11 are rotatably connected to both the left and right sides of the moving block 10, and pressing blocks 7 are rotatably connected to the opposite sides of the two rotating rods 11.

[0026] Specifically, after the frame is preliminarily built, rotating the knob 8 drives the threaded rod 9 to rotate. The moving block 10 is threadedly connected to the surface of the threaded rod 9. When the threaded rod 9 rotates, the moving block 10 moves along the surface of the threaded rod 9. The movement of the moving block 10 drives the rotating rod 11 to change the angle. At this time, the pressing block 7 moves its position as the angle of the rotating rod 11 changes. Finally, the pressing block 7 presses against the wall, and the frame is firmly fixed to the wall through friction. Moreover, this method does not require drilling holes in the wall, which is not only convenient for operation but also can protect the wall, ensuring the structural stability of the internal partition wall.

[0027] Refer to the attached Figure 4 As shown in the figure, sliding grooves 12 are opened on both the front and rear sides of the inner wall of the support member 3, and both pressing blocks 7 slide in the adjacent two sliding grooves 12.

[0028] Specifically, the sliding grooves 12 opened on the front and rear sides of the inner wall of the support member 3 provide a track for the movement of the extrusion block 7. When the user rotates the knob 8 to drive the threaded rod 9 to rotate, the moving block 10 threadedly connected to the threaded rod 9 starts to move, and the rotating rods 11 rotatably connected to both sides of the moving block 10 change their angles accordingly, thereby pushing the extrusion block 7 rotatably connected thereto to slide in the adjacent sliding grooves 12. The sliding grooves 12 play a guiding and limiting role for the extrusion block 7, enabling the extrusion block 7 to move closer to or away from the wall more stably along a predetermined direction, ensuring that the extrusion action is accurate and effective, thus fixing the frame to the wall more firmly, preventing the extrusion block 7 from shifting or shaking during movement, enhancing the stability and reliability of the entire fixing assembly, and improving the fixing effect and safety of the prefabricated sound-insulating interior partition wall structure.

[0029] Refer to the appendix Figure 4 and the appendix Figure 5 As shown in the figure, the limiting component includes a connecting block 25. The connecting block 25 is fixedly connected to the connecting rod 5. A second dovetail tenon 19 is fixedly connected to the left side of the connecting block 25. Two sliding rods 17 are fixedly connected to the right side of the inner wall of the connecting block 25. A locking member 16 is slidably connected between the two sliding rods 17.

[0030] Specifically, after the support member 3 and the connecting member 4 or two connecting members 4 are connected through the first dovetail tenon 13 and the dovetail groove 14, a groove for inserting the second dovetail tenon 19 will be formed at the connection of the two structures. At this time, inserting the second dovetail tenon 19 can further strengthen their connection, prevent loosening between the support member 3 and the connecting member 4 due to factors such as vibration, and ensure the stability of the frame structure. At the same time, the locking member 16 is inserted into the limiting groove 15 for fixation. The second dovetail tenon 19 fixes the support member 3 and the connecting member 4 to prevent them from loosening. At the same time, the locking member 16 is inserted into the limiting groove 15 to prevent the connecting block 25 and the second dovetail tenon 19 from sliding back and forth, resulting in loosening, and avoiding displacement or shaking of the connecting rod 5, thereby ensuring the stability and reliability of the entire prefabricated sound-insulating interior partition wall structure and providing a solid foundation for subsequent installation of the wall panel 1 and overall use.

[0031] Refer to the appendix Figure 5 As shown in the figure, two springs 18 are fixedly connected to the right side of the locking member 16. The right ends of the two springs 18 are both fixedly connected to the connecting block 25.

[0032] Specifically, when the connecting block 25 needs to be installed, the user can push the locking member 16 to retract and then smoothly insert it into the second dovetail tenon 19. After the second dovetail tenon 19 is inserted and fixed, release the locking member 16. Without complex operations, after installation, the locking member 16 automatically resets and inserts into the limiting groove 15 under the action of the spring 18. There is no need for manual precise alignment and fixation, saving installation time. The automatic resilience provided by the spring 18 enables the locking member 16 to tightly engage in the limiting groove 15, effectively preventing the accidental detachment of the locking member 16 due to external factors such as vibration and collision, enhancing the connection stability between the connecting block 25 and other components, and further improving the stability of the entire assembled sound-insulating interior partition structure, ensuring that it can reliably bear various external forces during long-term use and guaranteeing the use safety.

[0033] Refer to the appendix Figure 7 and the appendix Figure 8 For the installation component, it includes a fixing member 6. The fixing member 6 is fixedly connected to the front wall panel 1. A square block 20 is fixedly connected to the rear side of the fixing member 6, and a fixing plate 21 is fixedly connected to the front side of the rear wall panel 1.

[0034] Specifically, when the user installs the adjacent front and rear wall panels 1, first fix the fixing member 6 and the square block 20 to the front wall panel 1 with the first screw 2. At this time, insert the square block 20 into the intersection of the two connecting rods 5, and then align the fixing plate 21 on the front side of the rear wall panel 1 with the square block 20, and fix the rear wall panel 1, the fixing plate 21 and the square block 20 with the second screw 22, thereby firmly installing the two front and rear wall panels 1 together. Through the coordinated work of the fixing member 6, the square block 20 and the fixing plate 21 throughout the process, the rapid and stable installation of the wall panel 1 is achieved, simplifying the installation process, reducing the installation steps, realizing rapid installation. At the same time, this multi-component cooperative fixing method not only fixes the frame again, but also strengthens the wall panel 1 from multiple directions and positions, ensuring the stable installation of the wall panel 1, improving the overall structural stability of the interior partition, and further enhancing the installation efficiency and quality.

[0035] Refer to the appendix Figure 7 and the appendix Figure 8 For the front wall panel 1, the first screw 2 is arranged on the front side. The rear end of the first screw 2 penetrates and extends into the interior of the square block 20, and the first screw 2 is threadedly connected to the square block 20. For the rear wall panel 1, the second screw 22 is arranged on the rear side. The front end of the second screw 22 penetrates and extends into the interior of the square block 20, and the second screw 22 is threadedly connected to the square block 20.

[0036] Specifically, the front wallboard 1, the fixing member 6 and the square block 20 are fixed by the first screw 2 to achieve fixation according to requirements, and the fixing positions are all at the intersections of the two connecting rods 5, making the installation of the wallboard 1 more stable. At the same time, the rear wallboard 1, the fixing plate 21 and the square block 20 are fixed by the second screw 22, so as to realize the rapid installation of the rear wallboard 1. After the two wallboards 1 are installed, the fixing plate 21, the square block 20 and the fixing member 6 fix the two connecting rods 5 to prevent the two connecting rods 5 from shaking, realizing the rapid fixation of the internal frame.

[0037] See the appendix Figure 6 On the inner walls of multiple wallboards 1, reinforcing ribs 24 are fixedly connected, and the reinforcing ribs 24 are made of fiberglass.

[0038] Specifically, the reinforcing ribs 24 in multiple wallboards 1 can significantly enhance the structural strength of the wallboards 1. The reinforcing ribs 24 made of fiberglass have the characteristics of high strength and low density. They can increase the strength of the wallboards 1 without significantly increasing the weight of the wallboards 1, facilitating the handling and installation of the wallboards 1. They can effectively disperse the stress acting on the wallboards 1, avoid stress concentration resulting in cracking, breakage, etc. of the wallboards 1, extend the service life of the wallboards 1, and further improve the stability and safety of the overall structure of the prefabricated sound-insulating interior partition wall, ensuring that the interior partition wall can better withstand various external forces and maintain good performance during long-term use.

[0039] See the appendix Figure 3 and the appendix Figure 4 On the side of the two extrusion blocks 7 away from the rotating rod 11 is made of rubber, and serrated patterns are provided on the side of the two extrusion blocks 7 away from the rotating rod 11.

[0040] Specifically, the two extrusion blocks 7 are made of rubber, with good elasticity and flexibility. They can better fit the wall surface when extruding the wall, avoiding damage to the wall surface, while enhancing the friction force, making the extrusion fixation effect better. And the serrated patterns are provided on this side, further increasing the friction force with the wall, effectively preventing the extrusion blocks 7 from sliding on the wall, ensuring that the frame can be firmly fixed on the wall, and improving the stability and reliability of the overall structure of the prefabricated sound-insulating interior partition wall.

[0041] See the appendix Figure 2 and the appendix Figure 1 Multiple filling blocks 23 are all made of glass wool, and sealing rubber strips are provided between adjacent two wallboards 1.

[0042] Specifically, glass wool has good sound insulation performance, can effectively absorb and block sound, reduce noise interference in adjacent spaces, and improve the sound insulation effect of internal partition walls. At the same time, glass wool also has heat insulation performance, which helps to regulate indoor temperature and play an energy-saving role. A sealing strip is arranged between two adjacent wall panels 1 to fill the gap between the wall panels 1, further enhancing the sound insulation effect and preventing sound from leaking from the gap. The sealing strip can also play a waterproof and moisture-proof role, avoiding moisture intrusion from affecting the performance of the internal partition walls, extending the service life of the internal partition walls, and improving the practicality and durability of the overall structure.

[0043] The above-mentioned assembled soundproof inner partition wall structure has the following working steps: the user first places the support member 3 at the corner position, and uses the first dovetail tenon 13 and the dovetail groove 14 to connect the multiple connecting members 4 with the support member 3, thereby building a preliminary outer ring frame, and then places the multiple connecting rods 5 between the multiple support members 3 to support the entire frame, and then places the filling blocks 23 made of glass wool between the multiple connecting rods 5, and uses the good sound insulation performance of the glass wool to achieve the sound insulation function of the inner partition wall, and its heat insulation performance can also adjust the indoor temperature; After the frame is initially built, the user turns the knob 8 to drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 causes the moving block 10 to move along the surface of the threaded rod 9. The rotating rods 11 connected to the left and right sides of the moving block 10 will change their angles as the moving block 10 moves, thereby pushing the extrusion block 7 connected to it to slide in the slide grooves 12 opened on the front and rear sides of the inner wall of the support 3. The side of the extrusion block 7 away from the rotating rod 11 is made of rubber and has serrated patterns. When extruding the wall, the rubber material can better fit the wall surface to avoid damaging the wall and enhance the friction. The serrated patterns further increase the friction, effectively preventing the extrusion block 7 from sliding. The frame is firmly fixed to the wall through friction. This method does not require drilling holes in the wall, which is convenient for operation and protects the wall, ensuring the stability of the internal partition wall structure. When installing the connecting rod 5, after the support member 3 and the connecting member 4 or the two connecting members 4 are connected by the first dovetail tenon 13 and the dovetail groove 14, a groove for the second dovetail tenon 19 on the left side of the connecting block 25 to be inserted will be formed at the connection. After the second dovetail tenon 19 is inserted and fixed, the locking member 16 is released, and the spring 18 makes the locking member 16 automatically insert into the limiting grooves 15 opened on the left and right sides of the connecting member 4, preventing the connecting block 25 and the second dovetail tenon 19 from sliding forward and backward and causing looseness, thereby avoiding displacement or shaking of the connecting rod 5; When installing adjacent wall panels 1 before and after, the user first fixes the fixing member 6 and the square block 20 to the front wall panel 1 through the first screw 2. At this time, the square block 20 is inserted into the intersection of the two connecting rods 5, and then the fixing plate 21 fixedly connected to the front side of the rear wall panel 1 is aligned with the square block 20, and then the rear wall panel 1, the fixing plate 21 and the square block 20 are fixed through the second screw 22, so as to firmly install the two front and rear wall panels 1 together.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
