Description
Technical Field
[0001] This utility model relates to the field of building decoration technology, and in particular to a ceiling keel docking mechanism. Background Technology
[0002] Ceiling keel is the basic structural system used to build the ceiling frame in architectural decoration. It plays an important role in supporting and fixing the ceiling panels. It is divided into main keel and secondary keel. The main keel is the core load-bearing component, providing the main support for the entire ceiling. It is generally arranged with reasonable spacing. The secondary keel works in conjunction with the main keel to further subdivide the support area, making the ceiling structure more stable. Common materials include light steel and aluminum alloy, which have the advantages of high strength, light weight and corrosion resistance. Through reasonable keel layout and connection methods, ceilings of different shapes can be constructed to meet the aesthetic and functional needs of various architectural spaces. It is widely used in the decoration of shopping malls, office buildings and residential places.
[0003] In the field of architectural decoration, the ceiling keel structure is a key part of the ceiling structure. It not only affects the aesthetics of the ceiling, but also its stability and safety. In the past, the connection between the main keel and the secondary keel relied on simple welding or direct bolt fixing. Although the welding method provides a strong connection, the construction process is complicated, and the heat generated by welding can damage the keel material. It is also extremely inconvenient to dismantle or modify it later. Although the direct bolt fixing method is relatively simple to operate, the connection stability is not good. During long-term use, the bolts are prone to loosening due to the weight of the ceiling itself and external vibration factors, resulting in gaps at the keel connection, which in turn causes the ceiling to deform and crack, seriously affecting the service life and safety of the ceiling.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1:
[0029] Reference Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a ceiling keel docking mechanism, including a main keel 1, a secondary keel 2 is provided below the main keel 1, and both the main keel 1 and the secondary keel 2 are I-beams. A locking block 3 is snapped into the bottom of the main keel 1, and a docking component 4 is provided at the bottom of the locking block 3.
[0030] The main keel 1, as the core load-bearing component of the entire ceiling keel structure, provides the main support for the entire ceiling structure. The secondary keel 2 works in conjunction with the main keel 1 to further subdivide the support area of the ceiling, making the ceiling structure more stable. At the same time, the distribution of the secondary keel 2 can provide positioning and support for the installation of various decorative materials or equipment according to the design requirements of the ceiling. The setting of the clip 3 is used to provide the installation foundation for the docking component 4, so that the docking component 4 can establish a connection relationship with the main keel 1 through the clip 3. The setting of the docking component 4 can firmly connect the main keel 1 and the secondary keel 2 together through its internal structural design, forming a complete keel frame structure.
[0031] The docking assembly 4 includes a center plate 41 fixed to the bottom of the locking block 3. The inner wall of the center plate 41 is provided with a docking groove 42. Both sides of the center plate 41 are provided with locking plates 43. A protrusion 44 is fixed on one side of the locking plate 43, and the outer side of the protrusion 44 fits into the inner wall of the docking groove 42.
[0032] The center plate 41 is provided to provide a docking position for the protrusion 44 on the snap-fit plate 43, so as to achieve a fitting connection with the snap-fit plate 43. The two sets of snap-fit plates 43 fit into the docking groove 42 of the center plate 41 through the protrusion 44. At the same time, the second snap-fit groove 21 opened on the inner wall of the snap-fit plate 43 is interference-fitted with the outer side of the secondary keel 2, which can fix the secondary keel 2 in a suitable position and complete the docking of the main keel 1 and the secondary keel 2.
[0033] When connecting the main keel 1 and the secondary keel 2, firstly, the locking block 3 is inserted into the outer side of the main keel 1 through the first locking groove 20 on its inner wall, and is firmly locked into the bottom of the main keel 1, providing an installation base for the connecting assembly 4. Next, the connecting groove 42 on the inner wall of the center plate 41 provides a docking position for the protrusion 44 on the locking plate 43. The two sets of locking plates 43 are connected by the protrusion 44 and the connecting groove 42. At the same time, the second locking groove 21 on the inner wall of the locking plate 43 is inserted into the outer side of the secondary keel 2 through the interference fit, fixing the secondary keel 2 in a suitable position. Finally, the locking bolt 17 is inserted into the inner wall of the locking plate 43, passes through the positioning hole 18 on the inner wall of the center plate 41, and is tightened with the locking nut 19 to further strengthen the connection stability. In this way, the main keel 1 and the secondary keel 2 are tightly connected through the connecting assembly 4 to form a complete keel frame structure.
[0034] The top of the main keel 1 is fitted with multiple sets of M-shaped plates 5 by screws. Each side of the M-shaped plate 5 is provided with a first diagonal brace 6. An extension rod 7 is sleeved on the outer side of the first diagonal brace 6. A second diagonal brace 8 is slidably connected to the inner wall of the extension rod 7. Both ends of the extension rod 7 are provided with fasteners 9 for fixing the first diagonal brace 6 and the second diagonal brace 8.
[0035] The M-shaped plate 5 provides an installation base for the first diagonal brace 6. Simultaneously, the special shape of the M-shaped plate 5 can disperse stress to a certain extent, enhancing structural stability. The first diagonal brace 6, the second diagonal brace 8, and the extension rod 7 work together to form an adjustable diagonal bracing structure. This structure provides additional support to the main keel 1 and secondary keel 2 from the side, enhancing the overall deformation resistance of the ceiling keel structure. Especially when subjected to large loads or external impacts, it effectively prevents deformation or damage to the keel structure. Furthermore, since the extension rod 7 is sleeved on the outside of the first diagonal brace 6, and the inner wall of the extension rod 7 is slidably connected to the second diagonal brace 8, this sliding connection allows for adjustment of the overall length of the diagonal brace according to actual needs, adapting to the installation requirements of ceiling structures of different sizes and shapes. The fixing piece 9 is used to fix the first diagonal brace 6 and the second diagonal brace 8 after the diagonal brace length is adjusted, ensuring that the length of the diagonal brace remains stable during use, thereby guaranteeing the support effect.
[0036] Example 2:
[0037] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0038] Specifically, the fastener 9 includes a fixing ring 91 fixed to both ends of the extension rod 7, and the inner wall of the fixing ring 91 is threaded with multiple sets of fixing bolts 92.
[0039] After adjusting the positions of the first diagonal brace 6 and the second diagonal brace 8 in the extension rod 7, tightening the fixing bolt 92 will make the fixing bolt 92 firmly abut against the diagonal brace, thereby fixing the first diagonal brace 6 and the second diagonal brace 8 in a specific position on the extension rod 7, preventing the diagonal brace from sliding during use and ensuring the stability of the diagonal brace structure.
[0040] Specifically, both sides of the M-shaped plate 5 are fixed with first connecting seats 10, and the inner wall of the first connecting seat 10 is rotatably connected to one end of the first diagonal brace 6. One end of the second diagonal brace 8 is rotatably connected to the second connecting seat 11. The outer side of the secondary keel 2 is fitted with a mounting block 12, and the top of the mounting block 12 is fixedly connected to the bottom of the second connecting seat 11. The inner wall of the mounting block 12 is interference-fitted with the outer side of the secondary keel 2.
[0041] The first connecting seat 10 allows the first diagonal brace 6 to rotate around the first connecting seat 10, and the second connecting seat 11 allows the second diagonal brace 8 to rotate around the mounting block 12. This rotating connection method allows the diagonal brace to be adjusted at a certain angle according to the actual stress of the ceiling structure and installation requirements, so as to better play its supporting role. The mounting block 12 can fix itself firmly on the secondary keel 2, and at the same time, it can transfer the supporting force of the diagonal brace to the secondary keel 2, thereby supporting the secondary keel 2 and enhancing the stability of the entire ceiling keel structure.
[0042] Specifically, multiple sets of cross mounting plates 13 are installed on the top of the main keel 1, and mounting holes 14 are opened on the inner wall of the cross mounting plates 13.
[0043] By using the cross mounting plate 13 in conjunction with the mounting holes 14, the ceiling keel structure can be connected to the building structure, ensuring the stable installation of the entire ceiling.
[0044] Specifically, the inner wall of the cross mounting plate 13 is provided with two sets of reserved holes 15, and the inner wall of the reserved holes 15 is threaded with mounting bolts 16 for installing the cross mounting plate 13.
[0045] By using the pre-drilled hole 15 in conjunction with the mounting bolt 16, the cross mounting plate 13 can be fixed to the main keel 1.
[0046] Example 3:
[0047] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0048] Specifically, the inner wall of the snap-fit plate 43 is fitted with snap-fit bolts 17, the inner wall of the center plate 41 is provided with positioning holes 18, and the outer side of the snap-fit bolts 17 is threaded with snap-fit nuts 19.
[0049] By inserting the snap-fit bolt 17 into the positioning hole 18 of the snap-fit plate 43 and the center plate 41, and tightening it with the snap-fit nut 19, the connection strength between the snap-fit plate 43 and the center plate 41 can be further enhanced, ensuring the stability of the docking.
[0050] Specifically, the inner wall of the card block 3 is provided with a first card groove 20, and the inner wall of the first card groove 20 is interference-fitted with the outer side of the main keel 1. The inner wall of the card plate 43 is provided with a second card groove 21, and the inner wall of the second card groove 21 is interference-fitted with the outer side of the secondary keel 2.
[0051] Because the first slot 20 on the inner wall of the card block 3 is interference-fitted with the outer side of the main keel 1, this interference fit can firmly fix the card block 3 on the main keel 1, preventing loosening or falling off during use, and ensuring the safety and reliability of the structure. The design of the second slot 21 being interference-fitted with the outer side of the secondary keel 2 can firmly fix the secondary keel 2 on the docking component 4.
[0052] Working principle: When using this ceiling keel docking mechanism, firstly, the locking block 3 is fixedly locked to the bottom of the main keel 1 by using the first locking groove 20 on its inner wall to the outer side of the main keel 1 through interference fit, providing an installation base for the docking component 4. Next, the docking groove 42 on the inner wall of the center plate 41 provides a docking position for the protrusion 44 on the locking plate 43. The two sets of locking plates 43 are connected by the protrusion 44 and the docking groove 42. At the same time, the second locking groove 21 on the inner wall of the locking plate 43 is interference fit with the outer side of the secondary keel 2 to fix the secondary keel 2 in a suitable position. After that, the locking bolt 17 is inserted into the positioning hole 18 on the inner wall of the locking plate 43 and the center plate 41, and tightened with the locking nut 19 to further enhance the connection stability, so that the main keel 1 and the secondary keel 2 are tightly connected to form a complete keel frame.
[0053] In terms of support, multiple sets of M-shaped plates 5 are installed on the top of the main keel 1 with screws. Their special shape can disperse stress. The first connecting seat 10 on both sides of the M-shaped plate 5 is rotatably connected to the first diagonal brace 6. The second diagonal brace 8 is connected to the mounting block 12 sleeved on the secondary keel 2 through the second connecting seat 11. An extension rod 7 is sleeved on the outside of the first diagonal brace 6. The second diagonal brace 8 is slidably connected inside the extension rod 7. After adjusting the length according to actual needs, it is fixed with a fastener 9 to form an adjustable diagonal brace structure, which provides additional support to the main keel 1 and the secondary keel 2 from the side and enhances the resistance to deformation. In addition, the cross mounting plate 13 installed on the top of the main keel 1 is fixed to the main keel 1 through the reserved hole 15 and the mounting bolt 16, and then connected to the building structure through the mounting hole 14 to ensure that the entire ceiling is installed stably.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
