Description

Technical Field

[0001] This application belongs to the field of building construction technology and specifically relates to a stable support component for connecting ceiling decorative panels. Background Technology

[0002] Prefabricated ceilings (or integrated ceilings) are ceilings that integrate the base and surface finishes by assembling prefabricated products in a factory on-site according to design requirements, thus fulfilling various functions. The closest existing technology to this application is a prefabricated ceiling (e.g., authorization number CN211473038U), which has the following shortcomings, analyzed below:

[0003] First, when assembling and fixing the decorative panels of the existing prefabricated ceiling, screws (or bolts) are driven directly into the decorative panels. Since the decorative panels are relatively thin, the first screw or bolt may cause the decorative panels to bulge, crack, or deform, affecting the quality. At the same time, the decorative panels will no longer be intact, affecting recycling and reuse (such as in showrooms), and becoming an irreversible installation.

[0004] Secondly, the decorative panels of the aforementioned existing prefabricated ceilings (such as CN211473038U) require screws (or bolts) to be driven downwards during assembly. This necessitates the operator's head being higher than the keel, and the head must be tilted over the keel to perform the screwing operation, which is very inconvenient and results in low assembly efficiency. For example, in Embodiment 1, when assembling the decorative panels from left to right, driving screws on the left side of the connector is very difficult and extremely inconvenient. Summary of the Invention

[0005] This application provides a stable support component for connecting ceiling decorative panels to solve the technical problems mentioned above, such as the damage, cracking, and deformation of the decorative panels caused by screws (or bolts) being driven into them, as well as the inconvenience and low efficiency of assembly.

[0006] The technical solution adopted in this application is as follows:

[0007] A stable support component for connecting ceiling decorative panels includes a main keel, a support frame, a connector, a secondary keel, and decorative panels. The main keel extends longitudinally, and its bottom surface is provided with several support frames perpendicular to the main keel at intervals. The support frame includes a pair of downwardly extending support arms, and the ends of the two support arms are connected by a horizontal connecting plate to form an inverted trapezoidal cross section. The connector includes a vertical insertion section and a horizontal support section. The vertical insertion section is embedded in a guide groove opened on the inner side of the support arm, and the horizontal support section is connected to the top surface of the secondary keel by fasteners. The secondary keel extends laterally and has symmetrical snap-fit ​​grooves on both side walls. Elastic clamping elements are embedded in the snap-fit ​​grooves. The two sides of the decorative panel are respectively inserted into the snap-fit ​​grooves of the adjacent secondary keel.

[0008] Optionally, the elastic clamping member is formed by bending a metal sheet and includes a mounting part fixed to the bottom surface of the snap-fit ​​groove, an elastic arm extending toward the groove opening, and a limiting protrusion with its end folded upward.

[0009] Optionally, the horizontal connecting plate is provided with a downwardly protruding positioning strip, and the top surface of the secondary keel is provided with a positioning groove that mates with the positioning strip.

[0010] Optionally, the inner wall of the guide groove is provided with equidistant anti-slip teeth, and the vertical insertion section is provided with elastically deformable protrusions at the corresponding positions.

[0011] Optionally, the support arm forms an inclination angle of 45°-60° with the horizontal plane, and its lower end is provided with a limiting flange extending inward.

[0012] Optionally, a reinforcing rib is provided at the connection between the main keel and the support frame, and a slot is provided at the top of the support frame to engage with the reinforcing rib.

[0013] Optionally, the horizontal support section is provided with elongated adjustment holes, and the top surface of the secondary keel is provided with threaded mounting holes corresponding to the adjustment holes.

[0014] Optionally, the support frames are arranged at equal intervals along the length of the main keel, and the distance between adjacent support frames is an integer multiple of the width of the decorative panel.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0016] 1. The inverted trapezoidal structure formed by the support frame allows the secondary keel to be installed on a more stable support frame, avoiding structural deformation caused by long-term stress and improving the overall stability of the ceiling system. The vertical insertion section of the connector, in conjunction with the guide groove, provides multi-point positioning, effectively preventing the lateral slippage of the secondary keel and making the ceiling structure more stable.

[0017] 2. The flexible clamping parts formed by bending metal sheets create multiple elastic supports in the snap-fit ​​groove, allowing the decorative panel to be firmly inserted and kept stable. At the same time, it provides a certain amount of cushioning to reduce the loosening of the decorative panel due to thermal expansion and contraction. The design of the limiting protrusion can effectively prevent the decorative panel from falling off accidentally, thus improving the safety of the ceiling.

[0018] 3. The connectors are plug-in type and fit with the support frame, which does not require additional welding or complicated fasteners, reducing installation steps and improving construction efficiency. The adjustment holes on the secondary keel and the threaded mounting holes can flexibly adjust the position of the secondary keel to adapt to different sizes of decorative panels, increasing construction flexibility. The elastic clamps can be easily pried with tools, making it easy to disassemble and replace the decorative panels, which is convenient for maintenance and modification.

[0019] 4. By equidistantly arranging the support frame and setting up reinforcing ribs and slots, the overall support structure is subjected to uniform stress, which improves the seismic resistance. The positioning strips on the horizontal connecting plate cooperate with the positioning grooves on the secondary keel to form a multi-point constraint structure, which further improves the overall rigidity.

[0028] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0030] A stable support assembly for connecting ceiling decorative panels includes a main keel 1, a support frame 3, a connector 4, a secondary keel 2, and a decorative panel. The main keel 1 extends longitudinally, and its bottom surface is provided with several support frames 3 perpendicular to the main keel 1 at intervals. The support frame 3 includes a pair of downwardly extending support arms 5. The ends of the two support arms 5 are connected by a horizontal connecting plate 6 to form an inverted trapezoidal cross section. The connector 4 includes a vertical insertion section 41 and a horizontal support section 42. The vertical insertion section 41 is embedded in a guide groove 51 opened on the inner side of the support arm 5. The horizontal support section 42 is connected to the top surface of the secondary keel 2 by fasteners. The secondary keel 2 extends laterally and has symmetrical snap-fit ​​grooves 21 on both side walls. Elastic clamping members 7 are embedded in the snap-fit ​​grooves 21. The two sides of the decorative panel are respectively inserted into the snap-fit ​​grooves 21 of the adjacent secondary keel 2.

[0031] Furthermore, the elastic clamping member 7 is formed by bending a metal sheet and includes a mounting part 71 fixed to the bottom surface of the snap-fit ​​groove 21, an elastic arm 72 extending toward the groove opening, and a limiting protrusion 73 with its end folded upward.

[0032] The mounting part 71 is riveted to the bottom of the snap-fit ​​groove 21. The elastic arm 72 extends toward the groove and is pre-bent at a 10° angle. When the decorative panel is inserted, it squeezes the elastic arm 72. The limiting protrusion 73 deforms downward and slides into the groove, then resets and locks.

[0033] Furthermore, the horizontal connecting plate 6 is provided with a downwardly protruding positioning strip 61, and the top surface of the secondary keel 2 is provided with a positioning groove 22 that cooperates with the positioning strip 61.

[0034] By adopting the above technical solution, the bottom of the horizontal connecting plate 6 of the support frame 3 has a raised trapezoidal positioning strip 61, and the top surface of the secondary keel 2 has a corresponding trapezoidal groove. During assembly, the positioning strip 61 is embedded in the groove to limit the lateral displacement of the secondary keel 2.

[0035] Furthermore, the inner wall of the guide groove 51 is provided with equidistantly distributed anti-slip teeth, and the vertical insertion section 41 is provided with elastically deformable protrusions at corresponding positions.

[0036] Furthermore, the support arm 5 forms an inclination angle of 45°-60° with the horizontal plane, and its lower end is provided with a limiting flange 52 extending inward.

[0037] By adopting the above technical solution, the support arm 5 forms a 55° angle with the horizontal plane, and the bottom is bent inward and turned upside down. The connector 4 stops sliding down to the turned-up edge to prevent over-insertion.

[0038] Furthermore, a reinforcing rib 8 is provided at the connection between the main keel 1 and the support frame 3, and a slot is provided on the top of the support frame 3 to engage with the reinforcing rib 8.

[0039] Furthermore, the horizontal support section 42 is provided with elongated adjustment holes, and the top surface of the secondary keel 2 is provided with threaded mounting holes corresponding to the adjustment holes.

[0040] Furthermore, the support frames 3 are arranged at equal intervals along the length of the main keel 1, and the distance between adjacent support frames 3 is an integer multiple of the width of the decorative panel.

[0041] When using the stable support components of this application, the main keel 1 is longitudinally fixed to the top surface of the building, and the support frame 3 is vertically welded to the bottom surface of the main keel 1, with the spacing being an integer multiple of the width of the decorative panel. The vertical insertion section 41 of the connector 4 is embedded along the 55° inclined guide groove 51 of the support arm 5, and the horizontal support section 42 is fixed to the top surface of the secondary keel 2 by bolts. The two sides of the decorative panel are inserted into the snap-fit ​​grooves 21 of the adjacent secondary keel 2, and the limiting protrusions 73 in the snap-fit ​​grooves 21 are engaged with the groove wall recesses.

[0042] During installation, the decorative panel is inserted at an angle into the slot 21 of the secondary keel 2 on one side. The pressure plate is pressed down to deform the elastic clamp 7 on the other side and then it is locked in place. The limit protrusion 73 locks it in place. The weight of the decorative panel causes the secondary keel 2 to deflect downwards. The vertical section of the connector 4 is under tension. The support frame 3 decomposes the load into vertical pressure and horizontal thrust. The main keel 1 resists bending moment through reinforcing ribs. Under the action of seismic shear waves, the elastic clamp 7 allows the decorative panel to undergo slight displacement. The anti-slip teeth prevent the connector 4 from loosening.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
