Description

Technical Field

[0001] This invention relates to the field of ceiling keel installation structure technology, specifically to a silent ceiling keel integrated device and its usage method. Background Technology

[0002] Ceiling joists are the supporting framework structure installed between the ceiling and the decorative surface layer. They are mainly made of materials such as light steel, aluminum alloy, or wood. They serve to fix ceiling finishing materials such as gypsum board and mineral wool board, while also concealing pipelines such as wires, water pipes, and air conditioning pipes. The height and flatness of the joists can be adjusted to ensure the aesthetics and stability of the ceiling. They are an indispensable load-bearing and fixing component in ceiling decoration projects.

[0003] The existing ceiling keel structure design is relatively simple and lacks a special sound insulation structure. Furthermore, the connection between the keel body and the finishing material and building base is prone to forming sound bridges, causing indoor and outdoor sounds to interfere with each other through structural transmission. This is especially prominent in places with high requirements for sound insulation, such as residences, offices, and hospitals, where noise pollution is particularly severe. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a silent ceiling keel integrated device and its usage method, solving the problem that existing ceiling keel structures are relatively simple in design and lack specialized sound insulation features.

[0010] Preferably, the adsorption assembly further includes a sliding rod, the outer wall of which is slidably connected to the interior of the first fixed column. A magnetic block is fixedly connected to the top of the sliding rod, and the magnetic blocks are magnetically repelled on opposite sides. An elastic element is fixedly provided at the bottom of the sliding rod, and the end of the elastic element away from the sliding rod is fixedly provided to the inner bottom wall of the first fixed column. The outer wall of the magnetic block is slidably connected to the interior of the sliding block, and an iron ring is fixedly connected to the interior of the sliding block. The upper surface of the magnetic block is magnetically adsorbed onto the lower surface of the iron ring.

[0011] Preferably, a locking tooth assembly is installed inside the handle. The locking tooth assembly includes a limiting block. A fixing rod three is slidably connected to the outer wall of the limiting block. An upper hemisphere is fixedly connected to one end of the fixing rod three, and the other end of the fixing rod three is fixedly connected to the inside of the lead screw.

[0013] Preferably, the outer wall of the handle is fixedly connected to a plurality of connecting rods, and the outer wall of the connecting rods is slidably connected to the inside of the lead screw.

[0014] Preferably, the lead screw has multiple sliding grooves inside, the connecting rod is slidably connected to the sliding grooves, and the outer wall of the limiting block is slidably connected to the outer walls of the upper and lower hemispheres.

[0015] Preferably, a method for using a silent ceiling keel integrated device, the method comprising the following steps: S1. Multiple clip-type keels and secondary keels are spliced ​​together to form a keel frame. The keel frame is fixed to the preset position on the ceiling by the expansion bolts at the top of the hanger. Sound insulation board is installed on the outer wall of the clip-type keel. The sound insulation board is fixed by external buckles passing through the holes on the clip-type keel. Plasterboard is installed on the lower surface of the secondary keel to form a multi-layer composite protective structure and cavity. S2. When cable routing is required, press the handle to make the limit block slide along the fixed rod three and compress the elastic element three. Then release the handle. At this time, the elastic element three returns to its original state, causing the lower hemisphere to fit with the upper hemisphere to form a complete sphere, further extending the handle outward. Then rotate the handle to drive the lead screw to rotate, further driving the threaded block to slide on the outer wall of the lead screw and the fixed rod one, thereby driving the cable tray to extend out of the box. S3. When the threaded block moves, it will drive the fixed column to move synchronously. At this time, when the magnetic block moves with the sliding rod to the same vertical line as the iron ring in the sliding block, the magnetic block will attract the iron ring and stretch the elastic element. The sound generated by the attraction indicates that the cable board has reached the maximum stroke. Then, the operator will run the cable through the holes on the cable board. S4. After the cable arrangement is completed, turn the handle in the opposite direction to drive the screw to reverse. The threaded block will drive the cable tray to retract into the box. When the fixed column 1 moves to the point where magnetic block 1 and magnetic block 2 are facing each other, the magnetic repulsion between the two will cause magnetic block 1 to separate from the iron ring. The elastic element 1 will reset and drive magnetic block 1 to retract. The elastic element 4 will reset and drive the sliding block and iron ring back to their initial positions, thus completing the cable tray storage.

[0016] This invention provides a silent ceiling joist integrated device and its usage method. It has the following beneficial effects: 1. This invention utilizes a multi-layered composite protective structure formed by sound insulation boards and gypsum boards, along with the seamless splicing between adjacent sound insulation boards and the cavity formed between the sound insulation boards and gypsum boards, to further form a synergistic sound insulation system of "board barrier + cavity buffer," thereby significantly reducing sound energy transmission efficiency and improving the overall sound insulation performance of the ceiling joists.

[0017] 2. This invention enables the cables to be laid out synchronously with the ceiling joists by sliding the cable tray. At the same time, the cable tray can be stored and hidden when it is not needed, so that it does not affect the effect of stacking and transporting the secondary joists later.

[0018] 3. This invention uses the sound generated when the magnetic block and the iron ring are attracted to each other to intuitively and promptly convey to the construction personnel that the wiring board has reached its maximum stroke. This eliminates the need for additional tools to measure or repeated visual confirmation, and avoids damage to components such as the lead screw and threaded block due to excessive rotation of the handle.

[0019] 4. This invention extends the handle outward by pressing it, thereby preventing operators from being unable to turn the handle due to thicker fingers. Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a silent ceiling keel integrated device, including multiple clip-on keels 1, a secondary keel 2 installed below the clip-on keel 1, a hanger 3 fixedly connected to the upper surface of the clip-on keel 1, an expansion bolt 4 fixedly connected to the top of the hanger 3, multiple sound insulation panels 5 installed on the outer wall of the clip-on keel 1, and the opposite sides of two adjacent sound insulation panels 5 are staggered. Multiple holes 6 are opened inside the clip-on keel 1, the holes 6 are located above the sound insulation panels 5, and the distance between two adjacent holes 6 is 30cm. The lower surface of the secondary keel 2 is used to install gypsum board.

[0024] Specifically, a vibration-damping and sound-insulating pad is installed between the secondary keel 2 and the gypsum board. This pad provides vibration reduction and sound insulation when the gypsum board vibrates or conducts sound. First, the clip-on keel 1 and the secondary keel 2 are spliced ​​together. Then, the clip-on keel 1 and the secondary keel 2 are installed in a suitable position on the ceiling using hangers 3 and expansion bolts 4. The hangers 3 are fixed to the clip-on keel 1 using multiple nuts, with the inner layer of the nuts being metal and the outer layer being plastic. This improves the overall sound insulation effect of the hangers 3 and the clip-on keel 1. Finally, the sound insulation board 5 is installed. At a suitable location on the card-type keel 1, and through seamless splicing between two adjacent sound insulation panels 5, a seamless sound insulation effect is achieved. Then, multiple sound insulation panels 5 are fixed by external clips passing through multiple holes 6 opened in the card-type keel 1. Subsequently, gypsum board is installed under the secondary keel 2. At this time, a cavity is formed between the gypsum board and the sound insulation panel 5. Through the sound insulation panel 5, the seamless splicing between two adjacent sound insulation panels 5, the gypsum board, and the cavity between the sound insulation panel 5 and the gypsum board, the overall sound insulation performance of the ceiling keel is greatly improved.

[0025] Please see the appendix Figure 5 - Appendix Figure 7The secondary keel 2 has a housing 7 installed inside, and the housing 7 has an adjustment assembly 8 installed inside. The adjustment assembly 8 includes a threaded block 83, and a fixed rod 9 is slidably connected inside the threaded block 83. The outer wall of the fixed rod 9 is fixedly connected inside the housing 7. A cable tray 10 is fixedly connected to the outer wall of the threaded block 83, and the outer wall of the cable tray 10 is slidably connected inside the housing 7. The adjustment assembly 8 also includes a handle 81, the outer wall of the handle 81 is rotatably connected inside the housing 7, and a lead screw 82 is installed on the outer wall of the handle 81. The outer wall of the lead screw 82 is rotatably connected inside the housing 7, and the outer wall of the lead screw 82 is threadedly connected to the inside of the threaded block 83.

[0026] Specifically, after the ceiling installation of the card-type keel 1 and the secondary keel 2 is completed, when wiring is required, first turn the handle 81 to drive the lead screw 82 to rotate inside the housing 7, which in turn drives the threaded block 83 connected to the outer wall to move on the outer wall of the lead screw 82 and the fixing rod 9. When the threaded block 83 moves, the fixing action of the threaded block 83 and the cable tray 10 will drive the cable tray 10 to move. The cable tray 10 has multiple holes 6 of different sizes, which makes it convenient for the workers to select the appropriate hole 6 for wiring according to the actual situation. This allows the cables to be laid out synchronously with the ceiling keel, and the cable tray 10 can also be stored and hidden when it is not needed, so that it does not affect the effect of stacking and transporting the secondary keel 2 later.

[0027] Please see the appendix Figure 7 - Appendix Figure 9 A fixing post 11 is fixedly connected to the upper surface of the threaded block 83. An adsorption assembly 12 is installed inside the fixing post 11. The adsorption assembly 12 includes a sliding block 124. A fixing rod 13 is slidably connected inside the sliding block 124. The outer wall of the fixing rod 13 is fixedly connected to the inside of the housing 7. An elastic element 23 is fixedly installed on the outer wall of the fixing rod 13. A baffle 14 is fixedly installed at the end of the elastic element 23 away from the sliding block 124. A magnetic block 15 is fixedly connected to the upper surface of the baffle 14. The inside of the baffle 14 is fixedly connected to the outer wall of the fixing rod 13. The adsorption assembly 12 also includes a sliding block 124. The outer wall of the movable rod 122 is slidably connected to the inside of the fixed column 11. The top of the sliding rod 122 is fixedly connected to a magnetic block 121, and the magnetic blocks 121 and 15 are magnetically repelled on opposite sides. The bottom of the sliding rod 122 is fixedly provided with an elastic element 123. The end of the elastic element 123 away from the sliding rod 122 is fixedly provided on the inner bottom wall of the fixed column 11. The outer wall of the magnetic block 121 is slidably connected to the inside of the sliding block 124. An iron ring 125 is fixedly connected to the inside of the sliding block 124. The upper surface of the magnetic block 121 is magnetically attracted to the lower surface of the iron ring 125.

[0028] Specifically, when the threaded block 83 moves, the fixing action of the threaded block 83 and the fixed post 11 will drive the fixed post 11 to move, which in turn will drive the internal sliding rod 122 and elastic element 123 to move synchronously. When the sliding rod 122 moves, the fixing action of the sliding rod 122 and the magnetic block 121 will drive the magnetic block 121 to move. When the magnetic block 121 moves a certain distance and is on the same vertical line as the iron ring 125, the magnetic block 121 will attract the iron ring 125, slide into and fix itself inside the sliding block 124, and further drive the sliding rod 122 to slide upward. At the same time, the elastic element 123 is stretched. The sound generated when the magnetic block 121 and the iron ring 125 attract each other reminds the operator that the cable tray 10 has slid to its maximum stroke. When the cable tray 10 is retracted and hidden later, the reverse rotation of the handle 81 drives the screw 82 to reverse, which in turn drives the threaded block 83 to move. When the threaded block 83 moves back to its initial position, the magnetic block 121 drives the sliding block 124 and the iron ring 125 to slide on the outer wall of the fixed rod 13. At the same time, it cooperates with the baffle 14 to compress the elastic element 23. When it slides to the same vertical line as the magnetic block 15, the magnetic repulsion between the opposite sides of the magnetic blocks 121 and 15 causes the magnetic block 121 to detach from the iron ring 125. Under the action of the elastic element 123, the magnetic block 121 is reset. At this time, the elastic element 23 releases its own elastic force to reset the sliding block 124 and the iron ring 125. Thus, the sound generated at the moment the magnetic block 121 and the iron ring 125 are attracted can intuitively and promptly convey to the construction personnel that the cable board 10 has reached its maximum stroke. There is no need to use additional tools to measure or repeatedly confirm with the naked eye. This avoids the damage caused by excessive rotation of the handle 81, which may result in overload of components such as the lead screw 82 and the threaded block 83.

[0029] Please see the appendix Figure 10 and attached Figure 11The handle 81 has a locking assembly 16 installed inside. The locking assembly 16 includes a limiting block 161. A fixing rod 17 is slidably connected to the outer wall of the limiting block 161. One end of the fixing rod 17 is fixedly connected to an upper hemisphere 18, and the other end of the fixing rod 17 is fixedly connected to the inside of the lead screw 82. A lower hemisphere 19 is slidably connected to the outer wall of the fixing rod 17. The upper surface of the lower hemisphere 19 is attached to the lower surface of the upper hemisphere 18. An elastic element 20 is fixedly provided at the end of the handle 81 near the limiting block 161, and the end of the elastic element 20 away from the handle 81 is fixedly provided inside the lead screw 82. The locking assembly 16 also includes a fixing post 162. One end of the 62, away from the limiting block 161, is fixedly connected to the inside of the handle 81. The outer wall of the limiting block 161 is slidably connected to the inside of the second fixed post 162. An elastic element 163 is fixedly provided at the end of the limiting block 161 away from the third fixed rod 17. The end of the elastic element 163 away from the limiting block 161 is fixedly provided to the inside of the second fixed post 162. Multiple connecting rods 21 are fixedly connected to the outer wall of the handle 81. The outer wall of the connecting rod 21 is slidably connected to the inside of the lead screw 82. Multiple sliding grooves 22 are provided inside the lead screw 82. The connecting rods 21 are slidably connected to the sliding grooves 22. The outer wall of the limiting block 161 is slidably connected to the outer walls of the upper hemisphere 18 and the lower hemisphere 19.

[0030] Specifically, pressing the handle 81 moves the limiting block 161, the second fixing post 162, and the second elastic element 163, further causing the limiting block 161 to slide on the outer wall of the third fixing rod 17 and the lower hemisphere 19. While the handle 81 moves, it cooperates with the lead screw 82 to compress the third elastic element 20. When the limiting block 161 slides to the lower surface of the lower hemisphere 19, the pressure on the handle 81 is released, and the handle 81 is popped out by the third elastic element 20. Then, the limiting block 161 causes the lower hemisphere 19 to slide upward on the outer wall of the third fixing rod 17. When the lower hemisphere 19 slides upward and fits with the upper hemisphere 18 to form a complete sphere, the limiting block 161 will slide out from the outer wall of the lower hemisphere 19 and the upper hemisphere 18, further causing the handle 81 to extend outward, thereby achieving the effect of preventing the operator's fingers from being unable to turn the handle 81 due to their large size.

[0031] Please see the appendix Figure 1 - Appendix Figure 11 A method for using a silent ceiling keel integrated device, the method comprising the following steps: S1. Multiple clip-type keels 1 and secondary keels 2 are spliced ​​together to form a keel frame. The keel frame is fixed to the preset position on the ceiling by the expansion bolts 4 at the top of the hanger 3. Sound insulation board 5 is installed on the outer wall of the clip-type keel 1. The sound insulation board 5 is fixed by external buckles passing through the holes 6 on the clip-type keel 1. Plasterboard is installed on the lower surface of the secondary keel 2 to form a multi-layer composite protective structure and cavity. S2. When cable routing is required, press the handle 81 to make the limit block 161 slide along the fixed rod 17 and compress the elastic element 20. Then release the handle 81. At this time, the elastic element 20 returns to its original state, causing the lower hemisphere 19 to fit with the upper hemisphere 18 to form a complete sphere. This further extends the handle 81 outward. Then rotate the handle 81 to drive the lead screw 82 to rotate, which further drives the threaded block 83 to slide on the outer wall of the lead screw 82 and the fixed rod 9, thereby causing the cable tray 10 to extend out of the box 7. When S3 and threaded block 83 move, they will drive fixed column 11 to move synchronously. At this time, when magnetic block 121 moves with sliding rod 122 to the same vertical line as iron ring 125 in sliding block 124, magnetic block 121 attracts iron ring 125 and stretches elastic element 123. The sound generated by the attraction indicates that the cable board 10 has reached the maximum stroke. Then, the operator will run the cable through the hole 6 on the cable board 10. S4. After the cable arrangement is completed, the handle 81 is rotated in the opposite direction to drive the lead screw 82 to reverse. The threaded block 83 drives the cable tray 10 to retract into the housing 7. When the fixed post 11 moves to the point where the magnetic block 121 and the magnetic block 2 15 are facing each other, the magnetic repulsion between the two causes the magnetic block 121 to separate from the iron ring 125. The elastic element 123 resets and drives the magnetic block 121 to retract. The elastic element 4 23 resets and drives the sliding block 124 and the iron ring 125 back to their initial positions, thus completing the cable tray 10 storage.

[0032] Workflow: After the ceiling is completed with the card-type keel 1 and secondary keel 2, when wiring is being done, the handle 81 is turned to drive the lead screw 82 to rotate inside the housing 7, which further causes the threaded block 83 connected to the outer wall to move along the lead screw 82 and the fixed rod 9, thereby driving the cable tray 10 to move. The cable tray 10 has holes 6 of various specifications, which can be selected by the operators according to actual needs to thread the wires, so as to achieve synchronous layout of cables and ceiling keels. When not in use, the cable tray 10 can be stored and hidden to avoid affecting the subsequent stacking and transportation of the secondary keel 2.

[0033] When the threaded block 83 moves, it drives the fixed post 11 to move, which in turn drives the sliding rod 122 and the elastic element 123 to move synchronously. When the sliding rod 122 moves, it drives the magnetic block 121 to move. When the magnetic block 121 and the iron ring 125 are on the same vertical line, they attract each other and slide into the sliding block 124. At the same time, it pulls the sliding rod 122 upward and stretches the elastic element 123. The sound of the two attracting each other can remind the operator that the cable tray 10 has reached its maximum stroke. When the cable tray 10 is retracted, the handle 81 is rotated in the opposite direction to drive the screw 82 to reverse, further resetting the threaded block 83. When the threaded block 83 moves, it drives the magnetic block 121 to move. 21 drives the sliding block 124 and the iron ring 125 to slide along the fixed rod 2 13. At the same time, the baffle 14 compresses the elastic element 4 23. When the sliding reaches the same vertical line as the magnetic block 2 15, the opposite sides of the magnetic block 121 and the magnetic block 2 15 repel each other, causing the magnetic block 121 to detach from the iron ring 125. At this time, the elastic element 123 drives the magnetic block 121 to reset. The elastic element 4 23 will push the sliding block 124 and the iron ring 125 to reset. The sound generated by the mutual attraction between the magnetic block 121 and the iron ring 125 transmits the stroke signal, thereby achieving the effect of avoiding overload damage to components such as the lead screw 82 and the threaded block 83 due to excessive rotation of the handle 81.

[0034] By pressing the handle 81, the limiting block 161, the second fixing post 162, and the second elastic element 163 are moved. When the limiting block 161 moves, it slides along the outer wall of the third fixing rod 17 and the lower hemisphere 19. At the same time, the handle 81 cooperates with the lead screw 82 to compress the third elastic element 20. When the limiting block 161 slides to the lower surface of the lower hemisphere 19, the handle 81 is released. At this time, the third elastic element 20 pops out of the handle 81, further driving the limiting block 161 to push the lower hemisphere 19 to slide up along the third fixing rod 17, so that it fits with the upper hemisphere 18 to form a complete sphere. At this time, the limiting block 161 slides out from the outer wall of the lower hemisphere 19 and the upper hemisphere 18, thereby causing the handle 81 to extend outward, avoiding the effect of the operator's fingers being too thick to turn the handle 81.

10. A method of using a silent ceiling keel integrated device, characterized in that, The method of using the silent ceiling keel integrated device according to any one of claims 1-9 includes the following steps: S1. Splice multiple card-type keels (1) and secondary keels (2) to form a keel frame. Fix the keel frame to the ceiling preset position by expansion bolts (4) at the top of the hanger (3). Install sound insulation board (5) on the outer wall of the card-type keel (1). Fix the sound insulation board (5) by passing external buckles through the holes (6) on the card-type keel (1). Install gypsum board on the lower surface of the secondary keel (2) to form a multi-layer composite protective structure and cavity. S2. When cable routing is required, press the handle (81) to make the limit block (161) slide along the fixed rod three (17) and compress the elastic element three (20). Then release the handle (81). At this time, the elastic element three (20) returns to its original state, causing the lower hemisphere (19) to fit with the upper hemisphere (18) to form a complete sphere. This further extends the handle (81) outward. Then rotate the handle (81) to drive the lead screw (82) to rotate, further driving the threaded block (83) to slide on the outer wall of the lead screw (82) and the fixed rod one (9), thereby driving the cable tray (10) to extend out of the box (7). S3. When the threaded block (83) moves, it will drive the fixed column (11) to move synchronously. At this time, the magnetic block (121) moves with the sliding rod (122) to the same vertical line as the iron ring (125) in the sliding block (124). The magnetic block (121) attracts the iron ring (125) and stretches the elastic element (123). The sound generated by the attraction indicates that the cable tray (10) has reached the maximum stroke. Then, the operator will run the cable through the hole (6) on the cable tray (10). S4. After the cable arrangement is completed, turn the handle (81) in the opposite direction to drive the screw (82) to reverse. The threaded block (83) drives the cable tray (10) to retract into the box (7). When the fixed column (11) moves to the point where the magnetic block (121) and the magnetic block (15) are facing each other, the magnetic repulsion between the two causes the magnetic block (121) to separate from the iron ring (125). The elastic element (123) resets and drives the magnetic block (121) to retract. The elastic element (23) resets and drives the sliding block (124) and the iron ring (125) to return to their initial positions, thus completing the storage of the cable tray (10).
