Description

Technical Field

[0001] This utility model relates to the field of building keel, and more particularly to a three-dimensional aluminum ceiling prefabricated composite keel. Background Technology

[0002] In the field of architectural decoration, aluminum ceiling panels are widely used in interior ceiling projects due to their lightweight, corrosion resistance, and aesthetic appeal. Traditional ceiling joist systems mostly use fixed connection structures, and their installation process relies heavily on on-site processing and manual adjustments, such as fixing the joist components by welding or riveting.

[0003] While some prefabricated keel systems in existing technologies employ modular designs, they still suffer from significant drawbacks. Most publicly available keel structures are installed using simple snap-fit ​​methods, but their adjustment range is limited, failing to flexibly address the fine-tuning needs of different installation scenarios. Furthermore, the fastening mechanism is simplistic, relying solely on bolts for direct locking, which can easily loosen due to vibration or load changes during long-term use, affecting structural stability. In addition, the load transfer path design of traditional keel systems is not optimized, resulting in insufficient dispersion of vertical and horizontal loads, particularly in large-span or high-load scenarios, making them prone to localized deformation or even breakage.

[0004] Based on this, we propose a three-dimensional aluminum ceiling prefabricated composite keel. Utility Model Content

[0005] To address the technical problem of the simplistic installation methods of existing keel systems, this utility model provides a three-dimensional aluminum ceiling prefabricated composite keel system.

[0006] This utility model is achieved using the following technical solution: a three-dimensional aluminum ceiling prefabricated composite keel, including a fixing bolt, the bottom of the screw of the fixing bolt penetrating the wall, one end of a first shaft connected to the outside of the fixing bolt, the other end of the first shaft connected to a second shaft, and the connection between the first shaft and the second shaft being connected through a rotating shaft.

[0007] The mounting base is fixed on the first shaft, and the fixing base is installed on the upper surface of one of the second shafts. The movement of the fixing base is adjusted by the movement of the screw pusher.

[0008] A mounting base is fixedly connected to the top of the first shaft. A screw pusher is threaded through the inner side of the mounting base. A fixed base is inserted through the top of the screw pusher. A limit sleeve is installed on the top of the screw pusher. Two sets of limit sleeves are provided, and the two sets of limit sleeves are located on both sides of the fixed base.

[0009] There are two sets of second shafts, which are connected in a cross shape. The connection between the two sets of second shafts is positioned by a deflection axis. The outer side of the second shaft is integrally formed with a shaft frame. The top of each set of shaft frames is connected to a shaft movable block. One set of shaft movable blocks is directly connected to the assembly locking plate, and the other set of shaft movable blocks is connected to a sliding groove opened on the surface of the assembly locking plate to constrain the movement trajectory of the shaft movable block.

[0010] By rotating the screw pusher, the screw pusher rotates inside the mounting base, slowly pushing and moving within the mounting base. The limiting sleeve connected to the top of the screw pusher is pushed synchronously, causing the fixed base to move synchronously. The fixed base then moves the second shaft, which deflects around the rotation axis. Both sets of second shafts deflect around the deflection axis, causing the shaft bracket to deflect. The shaft bracket then drives the shaft movable block to slide inside the sliding groove, thus pushing the assembly locking plate to adjust its position. This allows for synchronous fine-tuning of the ceiling joist position, meeting different spatial layout requirements and enhancing the system's versatility and expandability.

[0011] The assembly fastening components include an assembly locking plate with a U-shaped side section and a U-shaped groove for engaging the ceiling joists.

[0012] As a further optimization of this utility model, the surface of the assembly locking plate is provided with an elongated adjustment and fastening groove. The adjustment and fastening groove is elongated and has two sets, upper and lower, which penetrate through the surface of the assembly locking plate.

[0013] As a further optimization of this utility model, a fastening plate overlaps the upper surface of the mounting locking plate, and a fastening bolt penetrates the surface of the fastening plate. The fastening bolt penetrates the fastening plate and the adjusting fastening groove to lock the ceiling keel that is limited inside the fastening plate.

[0014] As a further optimization of this utility model, the fastening plate is provided in multiple sets, which can be flexibly adjusted in position. The fastening plate can lock multiple sets of prefabricated ceiling joists at the same time, realizing the simultaneous assembly and installation of multiple sets of ceiling joists, and adapting to complex installation scenarios.

[0015] As a further optimization of this utility model, the assembly fastening component adopts a U-shaped cross-section assembly locking plate to form a plug-in connection with the ceiling keel; after the assembly locking plate initially positions the ceiling keel, the horizontal range can be adjusted by moving and adjusting the position of the fastening plate.

[0016] As a further optimization of this utility model, after the fastening plate is adjusted, it is locked by fastening bolts. The fastening bolts pass through the adjustment and fastening groove and abut against the upper surface of the ceiling keel, thereby locking the ceiling keel.

[0017] As a further optimization of this utility model, the mechanical transmission path formed by the cross-shaped second shaft and the deflection axis effectively disperses external forces and suppresses structural deformation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model achieves rapid plug-in installation of ceiling joists through the cooperative design of a U-shaped cross-section assembly locking plate and an adjusting fastening groove. The fastening plate can move flexibly along the long strip adjusting groove, and combined with the locking mechanism of the fastening bolts, it facilitates precise horizontal and vertical adjustment of the joists, significantly improving construction efficiency and reducing labor costs.

[0020] 2. This utility model adopts a double locking structure in which fastening bolts pass through the adjustment groove and abut against the keel surface to ensure the keel is firmly fixed. Vertical loads are transferred to the wall through the assembly of locking plates, fastening plates and fixing bolts, while horizontal loads are converted into axial forces by the cross-axis structure. The U-shaped cross section and multiple components work together to significantly improve the overall resistance to compression, bending and impact.

[0021] 3. This utility model, through the design of multiple sets of fastening plates and a sliding shaft movable block, supports the simultaneous locking of multiple sets of keels, adapting to complex installation scenarios. The screw pusher drives the shaft linkage mechanism to achieve synchronous fine adjustment of the keel position, meeting different spatial layout requirements and enhancing the system's versatility and scalability.

[0022] 3. This utility model effectively disperses external forces and suppresses structural deformation through the mechanical transmission path formed by the cross-shaped second shaft and the deflection axis. The synergistic effect of the U-shaped groove and the fastening plate double locking reduces the direct impact of vibration or load fluctuations on the keel, extends service life, and reduces maintenance costs.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example 1:

[0030] Please combine Figures 1-3 This embodiment proposes a three-dimensional aluminum ceiling prefabricated composite keel, including a fixing bolt 1, the bottom of the screw of the fixing bolt 1 penetrates the wall 12, one end of the first shaft 2 is connected to the outside of the fixing bolt 1, the other end of the first shaft 2 is connected to the second shaft 6, and the connection between the first shaft 2 and the second shaft 6 is through the rotating shaft 5.

[0031] It should be noted that the mounting base 3 is fixed on the first shaft 2, and the fixing base 41 is installed on the upper surface of one of the second shafts 6. The movement of the fixing base 41 is adjusted by the movement of the screw pusher 4.

[0032] A mounting base 3 is fixedly connected above the first shaft 2. A screw pusher 4 is threaded through the inner side of the mounting base 3. A fixed base 41 is threaded through the top of the screw pusher 4. A limit sleeve 42 is installed on the top of the screw pusher 4. Two sets of limit sleeves 42 are provided, and the two sets of limit sleeves 42 are located on both sides of the fixed base 41.

[0033] The second shaft 6 is provided in two sets, and the two sets of second shaft 6 are connected in a cross shape. The connection of the two sets of second shaft 6 is positioned by the deflection shaft 7. The outer side of the second shaft 6 is integrally formed with a shaft frame 8.

[0034] Both sets of shaft brackets 8 have shaft movable blocks 9 connected to their top ends. One set of shaft movable blocks 9 is directly connected to the assembly locking plate 111, while the other set of shaft movable blocks 9 is connected to the sliding groove 10 opened on the surface of the assembly locking plate 111, which is used to constrain the movement trajectory of the shaft movable blocks 9.

[0035] Specifically, by rotating the screw pusher 4, the screw pusher 4 rotates inside the mounting base 3. The screw pusher 4 slowly pushes and moves inside the mounting base 3, and the limiting sleeve 42 connected to the top of the screw pusher 4 is pushed synchronously. The limiting sleeve 42 drives the fixed base 41 to move synchronously. The fixed base 41 drives the second shaft 6 to move. The second shaft 6 deflects around the rotation axis 5. The two sets of second shafts 6 deflect around the deflection axis 7. The second shaft 6 drives the shaft frame 8 to deflect. The shaft frame 8 drives the shaft movable block 9 to slide inside the sliding groove 10. The assembly locking plate 111 is thus pushed to adjust its position, realizing synchronous fine adjustment of the position of the ceiling keel 13, meeting the needs of different spatial layouts, and enhancing the versatility and expandability of the system.

[0036] Assembly fastening assembly 11, which includes assembly locking plate 111, the side section of assembly locking plate 111 is U-shaped, and the U-shaped groove of assembly locking plate 111 is used to snap onto ceiling keel 13.

[0037] Specifically, the assembly fastening assembly 11 uses a U-shaped cross-section assembly locking plate 111 to form a plug-in connection with the ceiling joists 13; after the assembly locking plate 111 initially positions the ceiling joists 13, the position of the fastening plate 113 is adjusted to achieve horizontal adjustment; after the fastening plate 113 is adjusted, it is locked by fastening bolts 114, which pass through the adjusting fastening groove 112 and abut against the upper surface of the ceiling joists 13, thereby locking the ceiling joists 13.

[0038] More specifically, the fastening plate 113 is provided in multiple sets, which can be flexibly adjusted in position. The fastening plate 113 can lock multiple sets of prefabricated ceiling joists 13 at the same time, realizing the simultaneous assembly and installation of multiple sets of ceiling joists 13, adapting to complex installation scenarios.

[0039] It should be noted that the surface of the mounting locking plate 111 is provided with an elongated adjustment and fastening groove 112. The adjustment and fastening groove 112 is elongated and has two sets, upper and lower, which penetrate the surface of the mounting locking plate 111.

[0040] The upper surface of the mounting locking plate 111 is overlapped with a fastening plate 113, and a fastening bolt 114 passes through the surface of the fastening plate 113. The fastening bolt 114 passes through the fastening plate 113 and the adjusting fastening groove 112 to lock the ceiling joist 13 that is limited inside the fastening plate 113.

[0041] Specific implementation steps of this utility model:

[0042] This utility model relates to a three-dimensional aluminum ceiling prefabricated composite keel, and its specific working principle is as follows:

[0043] Modular assembly mechanism

[0044] The assembly fastening assembly 11 uses a U-shaped cross-section assembly locking plate 111 to form a plug-in connection with the ceiling joist 13. After the assembly locking plate 111 initially positions the ceiling joist 13, the position of the fastening plate 113 is adjusted to achieve horizontal adjustment. After the fastening plate 113 is adjusted, it is locked by fastening bolts 114. The fastening bolts 114 pass through the adjustment fastening groove 112 and abut against the upper surface of the ceiling joist 13, thereby locking the ceiling joist 13.

[0045] Meanwhile, multiple sets of fastening plates 113 are provided, which can be flexibly adjusted in position. The fastening plates 113 can simultaneously lock multiple sets of prefabricated ceiling joists 13, realizing the simultaneous assembly and installation of multiple sets of ceiling joists 13, adapting to complex installation scenarios.

[0046] In summary, the U-shaped cross-section assembly locking plate 111 and the adjusting fastening groove 112 are designed to enable quick plug-in installation of the ceiling joists 13. The fastening plate 113 can move flexibly along the elongated adjusting groove, and combined with the locking mechanism of the fastening bolts 114, it facilitates precise horizontal and vertical adjustment of the joists, significantly improving construction efficiency and reducing labor costs.

[0047] Position adjustment

[0048] By rotating the screw pusher 4, the screw pusher 4 rotates inside the mounting base 3. The screw pusher 4 slowly pushes and moves inside the mounting base 3. The limiting sleeve 42 connected to the top of the screw pusher 4 is pushed synchronously. The limiting sleeve 42 drives the fixed base 41 to move synchronously. The fixed base 41 drives the second shaft 6 to move. The second shaft 6 deflects around the rotation axis 5. The two sets of second shafts 6 deflect around the deflection axis 7. The second shaft 6 drives the shaft frame 8 to deflect. The shaft frame 8 drives the shaft movable block 9 to slide inside the sliding groove 10. The assembly locking plate 111 is thus pushed to adjust its position, realizing synchronous fine adjustment of the position of the ceiling keel 13, meeting the needs of different spatial layouts, and enhancing the versatility and expandability of the system.

[0049] Load delivery path

[0050] When the ceiling keel 13 is impacted.

[0051] Vertical load: Ceiling joists 13 → Assembly locking plate 111 → Fastening plate 113 → Fixing bolt 1 → Wall 12;

[0052] Horizontal load: converted into axial force through a cross-shaped axle structure;

[0053] Bending moment load: resisted by the U-shaped section and the double-locking structure.

[0054] In summary, the mechanical transmission path formed by the cross-shaped second shaft 6 and the deflection axis 7 effectively disperses external forces and suppresses structural deformation. The synergistic effect of the U-shaped groove and the fastening plate 113 double locking reduces the direct impact of vibration or load fluctuations on the keel, extends its service life, and reduces maintenance costs.

[0055] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
