Description

Technical Field

[0001] This application relates to the field of ceiling technology, and more particularly to a light steel ceiling. Background Technology

[0002] Most ceiling systems currently on the market use steel or aluminum alloy structures, which are typically quite complex in construction. These systems require multiple connectors and supports for installation, usually necessitating traditional fixing and connection methods such as welding or bolting. To ensure the stability and safety of the ceiling, each connection point in a traditional ceiling system requires rigorous construction and adjustment, a tedious and time-consuming process. Furthermore, the significant weight of the ceiling not only increases the difficulty of installation but also makes subsequent maintenance and disassembly challenging.

[0003] Existing ceiling systems suffer from a series of problems, including cumbersome installation and excessive weight. During installation, traditional connection methods require multiple adjustments and fixations, with each connection point demanding meticulous work, resulting in a lengthy and inefficient overall installation cycle. Furthermore, the significant weight of the ceiling structure increases the load on the system itself, placing additional stress on the building.

[0004] Therefore, it is necessary to propose a lightweight steel ceiling structure to overcome the shortcomings of existing technologies, such as complicated installation and excessive weight. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and propose a lightweight steel ceiling system, which aims to solve the problems of low efficiency and weight burden in the installation process of existing ceiling systems.

[0006] This application is achieved through the following technical solution:

[0007] This application discloses a light steel ceiling, including a hanger, a main keel, and a secondary keel. One end of the hanger is connected to the top, and the other end is fixedly connected to the main keel. The secondary keel is detachably and vertically connected to the main keel. The side wall of the main keel is provided with multiple snap-fit ​​structures. Each snap-fit ​​structure includes a fixing part and a snap-fit ​​part. The fixing part is located on the side wall of the main keel, and the snap-fit ​​part is fixedly connected to the bottom of the fixing part. The extension direction of the snap-fit ​​part is the same as the extension direction of the main keel. The secondary keel has a snap-fit ​​groove, and the extension direction of the snap-fit ​​groove is perpendicular to the extension direction of the secondary keel. The snap-fit ​​part can be snapped into the snap-fit ​​groove to vertically connect the secondary keel to the main keel.

[0008] In one embodiment of this application, the snap-fit ​​portion includes a connecting portion and a supporting portion. The connecting portion is fixedly connected to the bottom of the fixing portion and the supporting portion. The snap-fit ​​groove includes a connecting groove and a supporting groove. The connecting groove is disposed on the top surface of the secondary keel. The extending direction of the supporting groove is perpendicular to the extending direction of the secondary keel. The connecting groove and the supporting groove are connected and perpendicular to each other.

[0009] When the snap-fit ​​part is engaged in the snap-fit ​​groove, the connecting part is engaged in the connecting groove, and the supporting part is engaged in the supporting groove.

[0010] In one embodiment of this application, when the snap-fit ​​part is snapped into the snap-fit ​​groove, the bottom of the fixing part is in contact with the top surface of the secondary keel.

[0011] In one embodiment of this application, the hanger is located at the connection between the main keel and the secondary keel.

[0012] In one embodiment of this application, the main keel has a through hole, and the hanger rod passes through the through hole and is connected to the top.

[0013] In one embodiment of this application, the main keel is provided with an opening groove that communicates with the through hole. The opening groove is located on the side of the main keel facing the secondary keel, and one end of the hanger rod is threadedly connected to a nut and located in the opening groove.

[0014] In one embodiment of this application, the snap-fit ​​portions of the plurality of main keels are snapped into one of the snap-fit ​​grooves of any of the secondary keels.

[0015] In one embodiment of this application, the main keel is provided with a plurality of first connecting holes, each connecting hole being close to one of the snap-fit ​​structures; the secondary keel is provided with a plurality of connecting pieces, each connecting piece being provided with a second connecting hole, each connecting piece being close to the snap-fit ​​groove.

[0016] When the snap-fit ​​part is snapped into the snap-fit ​​groove, the first connecting hole and the second connecting hole are connected, and the fastener can pass through the first connecting hole and the second connecting hole to fix the secondary keel to the main keel.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] Each snap-fit ​​structure includes a fixing part and a snap-fit ​​part. The fixing part is located on the side wall of the main keel, and the snap-fit ​​part is fixedly connected to the bottom of the fixing part. The extension direction of the snap-fit ​​part is the same as the extension direction of the main keel. The secondary keel has a snap-fit ​​groove, and the extension direction of the snap-fit ​​groove is perpendicular to the extension direction of the secondary keel. The snap-fit ​​part can be snapped into the snap-fit ​​groove, thereby realizing a quick vertical connection between the secondary keel and the main keel, greatly improving installation efficiency. Because the secondary keel can be freely inserted and disassembled, construction personnel can adjust the installation position of the secondary keel according to actual needs, thereby improving the flexibility of the ceiling system and meeting the construction needs of different scenarios. Both the main keel and the secondary keel are made of lightweight steel, which significantly reduces the overall weight of the ceiling, thereby reducing the load on the building and improving structural safety.

[0033] Please refer to Figures 1 to 4 This application proposes a light steel ceiling 10, including a hanger 100, a main keel 200, and a secondary keel 300. One end of the hanger 100 is connected to the top, and the other end is fixedly connected to the main keel 200. The secondary keel 300 is detachably and vertically connected to the main keel 200. The side wall of the main keel 200 is provided with multiple snap-fit ​​structures 210. Each snap-fit ​​structure 210 includes a fixing part 211 and a snap-fit ​​part 212. The fixing part 211 is provided on the side wall of the main keel 200, and the snap-fit ​​part 212 is fixedly connected to the bottom of the fixing part 211. The extension direction of the snap-fit ​​part 212 is the same as the extension direction of the main keel 200. The secondary keel 300 is provided with a snap-fit ​​groove 310. The extension direction of the snap-fit ​​groove 310 is perpendicular to the extension direction of the secondary keel 300. The snap-fit ​​part 212 can be snapped into the snap-fit ​​groove 310 to vertically connect the secondary keel 300 and the main keel 200.

[0034] Specifically, one end of the hanger 100 is connected to the top, and the other end is fixedly connected to the main keel 200. The secondary keel 300 is detachably vertically connected to the main keel 200. To solve the problems of cumbersome installation, difficult adjustment, and excessive weight of existing ceiling systems, multiple snap-fit ​​structures 210 are provided on the side wall of the main keel 200. Each snap-fit ​​structure 210 includes a fixing part 211 and a snap-fit ​​part 212. The fixing part 211 is located on the side wall of the main keel 200, and the snap-fit ​​part 212 is fixedly connected to the bottom of the fixing part 211 and arranged along the extension direction of the main keel 200. At the same time, a snap-fit ​​groove 310 is opened on the secondary keel 300, the extension direction of which is perpendicular to the extension direction of the secondary keel 300, so that the snap-fit ​​part 212 can be inserted into the snap-fit ​​groove 310, thereby realizing a quick vertical connection between the secondary keel 300 and the main keel 200. The snap-fit ​​structure 210 allows the secondary keel 300 to be easily installed on the main keel 200 via a simple plug-in connection, significantly improving installation efficiency. Furthermore, this design effectively avoids structural instability caused by loose bolts or insufficient weld strength, ensuring the safety and durability of the ceiling system. Because the secondary keel 300 can be freely plugged in and removed, construction workers can adjust its installation position according to actual needs, thereby enhancing the flexibility of the ceiling system and meeting the construction requirements of different scenarios.

[0035] In summary, by optimizing the connection method between the main keel 200 and the secondary keel 300, the ceiling installation achieves higher efficiency, lighter weight, and improved stability. The installation process is simplified, making construction more convenient and reducing installation time and labor costs. The lightweight steel material significantly reduces the overall weight of the ceiling, thereby reducing the load on the building and improving structural safety. Furthermore, the snap-fit ​​part 212 can be snapped into the snap-fit ​​groove 310, improving the ease of disassembly and assembly of the secondary keel 300, making the maintenance, replacement, or adjustment of the ceiling system more efficient and avoiding the secondary construction costs associated with traditional fixing methods. Overall, this lightweight steel ceiling structure not only improves installation efficiency and structural stability but also enhances construction flexibility, providing the building ceiling industry with a more economical and practical technical solution.

[0036] Please refer to Figure 4 In one embodiment, the snap-fit ​​part 212 includes a connecting part 2121 and a supporting part 2122. The connecting part 2121 is fixedly connected to the bottom of the fixing part 211, and the connecting part 2121 is fixedly connected to the supporting part 2122. The snap-fit ​​groove 310 includes a connecting groove 311 and a supporting groove 312. The connecting groove 311 is disposed on the top surface of the secondary keel 300, and the extending direction of the supporting groove 312 is perpendicular to the extending direction of the secondary keel 300. The connecting groove 311 and the supporting groove 312 are connected and perpendicular to each other. When the snap-fit ​​part 212 is snapped into the snap-fit ​​groove 310, the connecting part 2121 is snapped into the connecting groove 311, and the supporting part 2122 is snapped into the supporting groove 312.

[0037] Specifically, the snap-fit ​​part 212 includes a connecting part 2121 and a supporting part 2122. The connecting part 2121 is fixedly connected to the bottom of the fixing part 211 on the side wall of the main keel 200, and the supporting part 2122 is fixedly connected to the connecting part 2121 and provides additional support. Correspondingly, a snap-fit ​​groove 310 is provided on the secondary keel 300. The snap-fit ​​groove 310 consists of a connecting groove 311 and a supporting groove 312. The connecting groove 311 is located on the top surface of the secondary keel 300, and the supporting groove 312 communicates with the connecting groove 311 and is perpendicular to the extension direction of the secondary keel 300. When the secondary keel 300 is installed on the main keel 200, the connecting part 2121 is inserted into the connecting groove 311, and the supporting part 2122 is inserted into the supporting groove 312, so that the snap-fit ​​part 212 can be firmly snapped onto the secondary keel 300. This structural design not only ensures that the secondary keel 300 is smoothly embedded into the main keel 200 during the connection process, but also enhances the shear resistance of the connection through the support part 2122, preventing the secondary keel 300 from loosening due to external forces, which helps to improve the stability and safety of the ceiling system.

[0038] Please refer to Figure 1 and Figure 3In one embodiment, when the snap-fit ​​part 212 is snapped into the snap-fit ​​groove 310, the bottom of the fixing part 211 is in contact with the top surface of the secondary keel 300.

[0039] Specifically, when the snap-fit ​​part 212 is engaged in the snap-fit ​​groove 310, the bottom of the fixing part 211 is in contact with the top surface of the secondary keel 300. The core function of this structural design is to enhance the connection stability through the direct contact between the fixing part 211 and the secondary keel 300, and to further reduce the displacement or shaking of the secondary keel 300 after installation.

[0040] Please refer to Figure 1 In one embodiment, the hanger 100 is located at the connection between the main keel 200 and the secondary keel 300.

[0041] Specifically, the hanger rod 100 is installed at the connection between the main keel 200 and the secondary keel 300, that is, at the intersection of the two structures, where load-bearing support is arranged. This design allows the supporting force of the hanger rod 100 to act directly on the connection point of the main keel 200 and the secondary keel 300, ensuring that the ceiling structure is subjected to more uniform force in the vertical direction and reducing deformation or loosening caused by uneven local force distribution.

[0042] Please refer to Figure 1 In one embodiment, the main keel 200 has a through hole (not marked in the figure), through which the hanger 100 passes and is connected to the top.

[0043] Specifically, the main keel 200 has through holes, through which the hanger 100 passes and connects to the top, allowing the hanger 100 to directly penetrate the main keel 200 instead of relying solely on external clamping or welding. This ensures that the direction of force on the hanger 100 is more stable, reducing swaying or deformation caused by lateral forces.

[0044] In one embodiment, the main keel 200 has an opening groove (not marked) that communicates with the through hole. The opening groove is located on the side of the main keel 200 facing the secondary keel 300. One end of the hanger 100 is threadedly connected to a nut and located in the opening groove.

[0045] Specifically, the main keel 200 has an opening slot communicating with the through hole, and one end of the hanger 100 is threadedly connected to and placed within this opening slot via a nut. The purpose of this design is to prevent the hanger 100 from obstructing the engagement of the secondary keel 300 with the main keel 200 after installation by adding an opening slot to the main keel 200. Furthermore, because the hanger 100 is threadedly connected, construction workers can fine-tune the fixing position of the hanger 100 as needed, ensuring that the main keel 200 and the secondary keel 300 can be smoothly engaged without affecting the overall stability of the ceiling.

[0046] Please refer to Figure 1In one embodiment, the snap-fit ​​portions 212 of a plurality of main keels 200 are snapped into the snap-fit ​​grooves 310 of any secondary keel 300.

[0047] Specifically, the snap-fit ​​parts 212 of multiple main keels 200 can be simultaneously snapped into the snap-fit ​​grooves 310 of the same secondary keel 300, allowing multiple main keels 200 to form a stable connection structure through the same secondary keel 300. This design makes the overall frame of the ceiling structure more compact and improves the load-bearing capacity of the ceiling through the joint force of multiple main keels 200.

[0048] Please refer to Figure 4 In one embodiment, the main keel 200 is provided with a plurality of first connecting holes 220, each connecting hole being close to one of the snap-fit ​​structures 210; the secondary keel 300 is provided with a plurality of connecting pieces 320, each connecting piece 320 being provided with a second connecting hole 321, each connecting piece 320 being close to the snap-fit ​​groove 310.

[0049] When the snap-fit ​​part 212 is snapped into the snap-fit ​​groove 310, the first connecting hole 220 and the second connecting hole 321 are connected, and the fastener 400 can pass through the first connecting hole 220 and the second connecting hole 321 to fix the secondary keel 300 to the main keel 200.

[0050] Specifically, the main keel 200 has multiple first connecting holes 220, each close to a corresponding snap-fit ​​structure 210. Meanwhile, the secondary keel 300 has multiple connecting pieces 320, each with a second connecting hole 321 close to a snap-fit ​​groove 310. When the snap-fit ​​groove 310 of the secondary keel 300 is inserted into the snap-fit ​​part 212 of the main keel 200, the first connecting holes 220 and second connecting holes 321 can be aligned. At this point, construction workers can use fasteners 400 (such as screws, rivets, or bolts) through the aligned connecting holes to provide additional mechanical fixation to the main keel 200 and the secondary keel 300.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
