Description

Technical Field

[0001] This utility model relates to the field of decorative keel support technology, and in particular to an indoor decorative keel support. Background Technology

[0002] In the field of interior decoration, light steel keel ceiling system is widely used due to its advantages such as high structural strength, convenient construction and good fire resistance. The system is usually composed of main keel suspended from the floor by hangers, secondary keel arranged perpendicular to the main keel, as well as edge keel and cross bracing keel, etc., which together form a stable grid-like frame for installing various decorative panels.

[0003] Currently, most existing interior decorative keel supports adopt traditional installation methods. The main keel is connected to the hanger rod through hangers and adjusted to be horizontal. The secondary keel is fastened with screws and clamped to the bottom of the main keel with special hangers. During construction, workers need to first lay out the positioning on the floor slab according to the design drawings, and then use measuring tools to determine the installation position of each secondary keel on the main keel before fixing it. The connection between the secondary keel and the edge keel is usually done by direct butt joint or by fixing with connectors. Its length is mostly prefabricated or cut on site according to the actual spacing.

[0004] However, existing technologies rely heavily on tools for connecting the main and secondary keels, whether it's tightening screws or using specialized clips, making rapid connection difficult. Furthermore, the positioning of the secondary keel depends on manual measurement and marking with a tape measure. Since different construction workers have different measuring habits, and repeated measurements can lead to accumulated errors, the vertical connection accuracy between the secondary and main keels is difficult to guarantee. This results in some secondary keels being misaligned, causing local height differences in the entire keel grid, affecting the flatness of the subsequent decorative panel installation. Additionally, the tool operation and repeated measurement steps significantly increase construction time and reduce overall construction efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an indoor decorative keel support, which aims to improve the problem that the existing technology relies on tools in the connection process of the main and secondary keels and is prone to cumulative errors after multiple measurements by construction workers, thus affecting the overall flatness of the keel grid and the construction efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an indoor decorative keel support, including a threaded hanger rod, one end of which is fixedly connected to an expansion bolt, and the other end of which is threadedly connected to two nuts. A hanger is provided between the two nuts, a main keel is provided on the inner wall of the hanger, a plurality of connecting plates are provided on the outer wall of the main keel, a clamping assembly is provided between the main keel and the connecting plates, a clip is fixedly connected to the lower surface of the connecting plate, and a secondary keel is provided on the outer wall of the clip. The clamping assembly includes a clamping hole and a clamping rod. The clamping holes are evenly distributed on the upper surface of the main keel. The outer wall of the clamping rod is slidably connected to the inner wall of the connecting plate. A sliding rod is slidably connected to the inner wall of the clamping rod. One end of the sliding rod is fixedly connected to one side of the inner wall of the connecting plate. A spring is sleeved on the outer wall of the sliding rod. One end of the spring is fixedly connected to one side of the inner wall of the connecting plate, and the other end of the spring is fixedly connected to one end of the clamping rod. The outer wall of the clamping rod is slidably connected to the inner wall of the clamping hole.

[0007] The above technical solution uses expansion bolts to fix the threaded hanger to the ceiling. Two nuts cooperate with the hanger to achieve flexible adjustment of the main keel's suspension height and level. The clamping assembly uses a clamping rod, sliding rod, and spring to cooperate with the clamping hole to achieve quick clamping and positioning of the connecting plate and the main keel. The clamping component connects the connecting plate and the secondary keel. The connection of the main and secondary keels can be completed without tools. At the same time, the prefabricated clamping hole eliminates the cumulative measurement error, ensures the vertical connection accuracy of the main and secondary keels, and improves the flatness of the keel grid and construction efficiency.

[0008] Preferably, a telescopic keel is slidably connected to the inner wall of the secondary keel, and a side keel is provided at one end of the telescopic keel.

[0009] Through the above technical solution, by sliding the telescopic keel on the inner wall of the secondary keel, combined with the edge keel at one end of the telescopic keel, the extension length of the telescopic keel can be adjusted according to the flatness of the wall surface, solving the problem of the spacing between the edge keel and the secondary keel when the wall surface is uneven, ensuring that the edge of the ceiling fits tightly with the wall surface through the edge keel, and ensuring the flatness of the ceiling installation.

[0010] Preferably, a cross brace is provided on the opposite side of the secondary keel, and the secondary keel and the cross brace are connected by a hanger.

[0011] The above technical solution connects the horizontal bracing keel to adjacent secondary keels using hangers, so that the horizontal bracing keel and the secondary keel form a horizontal support structure, thereby enhancing the connection strength between the secondary keels.

[0012] Preferably, the inner wall of the connecting plate is symmetrically provided with protruding rods on the upper and lower sides, and the outer wall of the main keel is symmetrically provided with grooves on the upper and lower sides, and the outer wall of the protruding rods is slidably connected to the inner wall of the grooves.

[0013] Through the above technical solution, the connecting plate 1's protrusion and the main keel's groove slide together, providing guidance for the movement of the connecting plate 1 along the main keel, preventing the connecting plate 1 from shifting or falling off when sliding, ensuring the stability of the connecting plate 1 when it drives the secondary keel to adjust its position, and ensuring the vertical installation accuracy of the secondary keel and the main keel.

[0014] Preferably, the inner wall of the telescopic keel is fixedly connected to a second connecting plate, and the inner wall of the second connecting plate is symmetrically provided with clamping plates on the left and right sides.

[0015] Through the above technical solution, the connecting plate 2 provides a mounting base for the telescopic adjustment mechanism, and the symmetrically arranged card plates inside it are used to engage with the card holes 2 on the secondary keel.

[0016] Preferably, the outer wall of the secondary keel is provided with two symmetrical locking holes, and the inner wall of the two locking holes is slidably connected to the outer wall of the locking plate.

[0017] Through the above technical solution, the second locking hole on the secondary keel cooperates with the locking plate on the telescopic keel to perform a locking motion, thereby achieving the effect of reliably locking the telescopic keel in multiple predetermined positions and ensuring the structural strength and stability after adjustment.

[0018] Preferably, the inner wall of the telescopic keel is provided with a second spring, and the two ends of the second spring are respectively located on opposite sides of the two clamping plates.

[0019] Through the above technical solution, the second spring is used to provide a continuous outward pushing force to the two locking plates, so that the locking plates can automatically lock into the second locking hole when there is no external force intervention, thus ensuring the convenience of operation of the telescopic adjustment mechanism and the reliability after locking.

[0020] Preferably, the upper surface of the connecting plate two is provided with a sliding groove, and a lever is slidably connected to the inner wall of the sliding groove. The lower surface of the lever is fixedly connected to the upper surface of the card plate.

[0021] Through the above technical solution, the lever works in conjunction with the slide groove to slide, thereby driving the two locking plates to overcome the elastic force of the second spring and retract inward, thus disengaging the locking plates from the second locking hole and realizing the adjustment of the length of the telescopic keel.

[0022] This utility model has the following beneficial effects: 1. In this utility model, by setting a groove on the main keel and slidingly engaging with the protrusion of the connecting plate, the secondary keel is hung on the main keel through the hanger and the connecting plate. Then, the position of the secondary keel is adjusted by sliding the connecting plate, and the connecting plate is connected to the main keel by the clamping assembly. Thus, quick connection and positioning can be achieved without tools. Furthermore, by using the prefabricated standard-distance clamping holes, the accumulated error of traditional measurement is eliminated, and the vertical connection between the secondary keel and the main keel is efficiently achieved, thereby improving the overall flatness of the keel grid and the construction efficiency.

[0023] 2. In this utility model, by moving the lever, the card plate can be disengaged from the second card hole, allowing the telescopic keel to slide inside the secondary keel. After adjusting the length, the second spring rebounds and locks in place, thus eliminating the need to repair the wall surface or twist the keel. This solves the problem of the gap between the side keel and the secondary keel when the wall surface is uneven, ensuring that the edge of the ceiling fits tightly against the wall surface, thereby ensuring the flatness of the installation.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0027] Reference Figure 1 - Figure 5This utility model provides an embodiment of an interior decorative keel support, including a threaded hanger 1 for providing suspension support and height adjustment. One end of the threaded hanger 1 is fixedly connected to an expansion bolt 2 for fixing the entire keel support to the building roof. The other end of the threaded hanger 1 is threadedly connected to two nuts 3, which are used to clamp and fix the hanger 4 and adjust the height of the main keel 5. A hanger 4 for connecting the hanger 4 and the main keel 5 is provided between the two nuts 3. The main keel 5 is provided on the inner wall of the hanger 4. The main keel 5 serves as the main load-bearing and installation foundation of the entire ceiling system. The wall is provided with multiple connecting plates 7, which are used to connect the main keel 5 and the secondary keel 9. A clamping component is provided between the main keel 5 and the connecting plate 7. A clip 8 for hanging the secondary keel 9 is fixedly connected to the lower surface of the connecting plate 7. The secondary keel 9 is provided on the outer wall of the clip 8. The secondary keel 9 serves as a secondary load-bearing and installation frame and is arranged perpendicularly to the main keel 5 to form a grid. A telescopic keel 10 is slidably connected to the inner wall of the secondary keel 9. A side keel 11 is provided at one end of the telescopic keel 10. A cross brace keel 13 is provided on the opposite side of the secondary keel 9. The secondary keel 9 and the cross brace keel 13 are connected by a hanger 12.

[0028] Specifically, by rotating the two nuts 3 on the threaded hanger 1, the hanger 4 can be clamped and positioned, thereby flexibly adjusting the lowering height of the entire keel support and ensuring that the main keel 5 is horizontal after installation. The hanger 4 connects to and clamps the main keel 5, suspending the main keel 5 on the threaded hanger 1, forming the main load-bearing body. The telescopic keel 10 is generally set at the connection with the side keel 11 in conjunction with the secondary keel 9. The telescopic keel 10 is used to flexibly adjust the edge length according to the actual size of the site. The side keel 11 is fixed to the walls around the room, serving as the boundary outline of the ceiling and providing installation endpoints for the telescopic keel 10 and the secondary keel 9. The hanger 12 is used to connect the secondary keel 9 with the cross brace keel 13, enhancing the overall stability and integrity of the keel grid.

[0029] Reference Figure 2 and Figure 3 The clamping assembly includes a clamping hole 6 and a clamping rod 16. The clamping holes 6 are evenly distributed on the upper surface of the main keel 5. The outer wall of the clamping rod 16 is slidably connected to the inner wall of the connecting plate 7. The inner wall of the clamping rod 16 is slidably connected to a sliding rod 14 that provides sliding guidance for the clamping rod 16 and ensures clamping accuracy. One end of the sliding rod 14 is fixedly connected to one side of the inner wall of the connecting plate 7. A spring 15 is sleeved on the outer wall of the sliding rod 14. The spring 15 is used to provide elastic force for the clamping rod 16 to automatically reset, thereby realizing automatic clamping. One end of the spring 15 is fixedly connected to one side of the inner wall of the connecting plate 7, and the other end of the spring 15 is fixedly connected to one end of the clamping rod 16. The outer wall of the clamping rod 16 is slidably connected to the inner wall of the clamping hole 6. The inner wall of the connecting plate 7 is symmetrically provided with protruding rods 23 on the upper and lower sides. The outer wall of the main keel 5 is symmetrically provided with grooves 24 on the upper and lower sides to provide sliding tracks for the protruding rods 23. The outer wall of the protruding rods 23 is slidably connected to the inner wall of the grooves 24.

[0030] Specifically, the protruding rod 23 on the connecting plate 7 slides in conjunction with the groove 24 on the main keel 5, allowing the secondary keel 9 to slide and be pre-positioned along the length of the main keel 5. Pressing the locking rod 16 overcomes the elasticity of the spring 15 to release the lock and allow sliding. After releasing, the spring 15 rebounds and drives the locking rod 16 to engage in the pre-made locking hole 6. The locking hole 6 is a positioning point with a standard distance pre-made during the production of the main keel 5, allowing the locking rod 16 to engage. This enables quick connection and fixation without tools. The standard distance locking hole 6 eliminates the cumulative error caused by traditional measurement, effectively ensuring the perpendicularity of the secondary keel 9 and the main keel 5, greatly improving construction efficiency and the overall flatness of the keel grid.

[0031] Reference Figure 4 and Figure 5 A connecting plate 18 is fixedly connected to the inner wall of the telescopic keel 10. A locking plate 20 is symmetrically arranged on the left and right sides of the inner wall of the connecting plate 18. The outer wall of the secondary keel 9 is symmetrically provided with locking holes 17 for providing multiple locking positions for the locking plates 20 of the telescopic keel 10. The inner wall of the locking holes 17 is slidably connected to the outer wall of the locking plates 20. A spring 19 is provided on the inner wall of the telescopic keel 10. The spring 19 is used to provide elastic force for the locking plates 20 to automatically reset and achieve automatic locking. The two ends of the spring 19 are respectively set on the opposite side of the two locking plates 20. A groove 22 is provided on the upper surface of the connecting plate 18 to constrain the movement trajectory of the lever 21. A lever 21 is slidably connected to the inner wall of the groove 22 for the operator to move to control the unlocking of the locking plates 20. The lower surface of the lever 21 is fixedly connected to the upper surface of the locking plates 20.

[0032] Specifically, by moving the lever 21, the two side plates 20 compress the spring 19 and disengage from the locking hole 17, allowing the extension of the telescopic keel 10 to be freely slidable and adjusted. After being released, the spring 19 rebounds, causing the plate 20 to engage in the new locking hole 17 and lock in place. This allows the keel to adapt to uneven walls without the need to cut or twist components, ensuring a tight fit between the ceiling edge and the wall and guaranteeing a level installation.

[0033] Working principle: When installing and using the interior decoration keel support, first complete the site preparation and material inspection. Then, according to the design plan, mark the ceiling outline on the surrounding walls and mark the suspension points of the hangers on the ceiling. Install the edge keel 11 along the wall. Then, fix the threaded hanger 1 to the predetermined suspension point position on the ceiling with expansion bolts 2 and clamp and position the hanger 4 with two nuts 3. Rotating the nuts 3 can flexibly adjust the suspension height and level of the main keel 5 to ensure that the main keel 5 is level and flat. The main keel 5 is connected to the threaded hanger 1 through the hanger 4 to form the load-bearing main body. Then, insert the secondary keel 9 into the clip 8 of the connecting plate 7, align the protrusion 23 on the connecting plate 7 with the groove 24 and slide it onto the main keel 5. Align the clip 16 with the clip hole 6, and achieve quick clamping by the spring 15 rebounding. When it is necessary to adjust the position of the secondary keel 9 on the main keel 5, press the clip 16 and slide it along the slide bar 14 to disengage the clip 16 from the clip hole 6, so that the protrusion 23 on the connecting plate 7 slides in the groove 24 of the main keel 5 to the corresponding clip hole 6 position. Then release the clip 16 and achieve clamping by the spring 15 rebounding, thus completing the vertical connection between the secondary keel 9 and the main keel 5. Secondly, the operator can move the lever 21 to compress the spring 19 of the clamping plate 20, causing the clamping plate 20 to disengage from the locking hole 17. This allows the telescopic keel 10 to slide freely within the secondary keel 9. After the telescopic keel 10 extends a certain length, the lever 21 is released and the spring 19 rebounds, causing the clamping plate 20 to engage with the corresponding locking hole 17 on the secondary keel 9. This ensures that the telescopic keel 10 is accurately installed on the edge keel 11, thereby solving the problem of potential gaps between the edge keel 11 and the secondary keel 9 when the wall surface is uneven, and ensuring that the edge of the ceiling fits tightly against the wall surface. Finally, the horizontal bracing keel 13 is connected to the adjacent secondary keel 9 via the hanger 12 to further enhance the overall stability.
