Description

Technical Field

[0001] The present invention relates to the technical field of building decoration, in particular to a suspended ceiling structure. Background Art

[0002] In modern buildings, ceilings often contain various functional pipelines or support structures. To enhance the overall aesthetics of the building, suspended ceilings are often installed to enclose or conceal these pipelines and support structures. Installing a suspended ceiling typically requires workers to place aluminum panels on a keel and then secure them to the keel using multiple clips. This process is time-consuming and inefficient.

[0003] In order to simplify the installation process of aluminum plates and keels, relevant technologies have proposed a hook-type aluminum plate ceiling assembly. The ceiling assembly includes a plug-in hook block and an aluminum plate body. The keel body can also be connected and fixed with the aluminum plate body with the help of the hook block. The connection between the hook block and the aluminum plate body is easy, the construction time is reduced, and the construction efficiency is improved.

[0004] However, in the above-mentioned hook-type aluminum plate ceiling assembly, the connection between the hooking block and the aluminum plate body is only achieved by overlapping. The connection reliability between the hooking block and the aluminum plate body is poor and it is difficult to withstand multi-directional loads. During actual use, it is easy for external force impact and other factors to cause the connection between the hooking block and the aluminum plate body to fail, and the structural integrity of the ceiling assembly is poor. Summary of the Invention

[0005] In view of the above problems, an object of the present invention is to provide a suspended ceiling structure, which can improve the connection strength and connection reliability between the suspended ceiling panel and the hooking keel, and improve the structural integrity of the suspended ceiling structure.

[0006] To achieve the above objectives, the following technical solutions are provided:

[0007] The present invention provides a suspended ceiling structure, comprising:

[0008] The ceiling panel is provided with an overlapping portion and an inserting portion, wherein the inserting portion and the overlapping portion are arranged at an angle and connected to each other;

[0009] Multiple groups of keel assemblies are arranged at intervals along the length direction of the ceiling panel. Each group of keel assemblies includes connected main keels and hooking keels. The main keels are arranged above the ceiling panel and can be connected and fixed to the ceiling. The hooking keels are provided with a first card slot and a second card slot that are connected to each other. The overlapping part is at least partially overlapped with the first card slot, and the plug-in part is plug-fitted with the second card slot.

[0010] Specifically, the included angle between the inserting portion and the overlapping portion is greater than 90° and less than 180°, and the second card slot is opened below the first card slot.

[0011] Exemplarily, the plug-in portion is in the shape of an inclined plate or an arc plate.

[0012] Optionally, the hooking keel is further provided with an installation groove, and the main keel is passed through the installation groove and abuts against the bottom of the installation groove.

[0013] Specifically, the ceiling structure further includes a locking member, one end of which is locked to the groove wall of the first slot via the main keel and the overlapping portion in sequence, and the other end is pressed against the top surface of the hooking keel.

[0014] Optionally, the ceiling panel is provided with an avoidance gap, and the hooking keel can slide to a preset position through the avoidance gap along the length direction of the ceiling panel.

[0015] Preferably, a chamfer is provided on one side of the hooking keel away from the bottom of the first slot along the length direction of the main keel.

[0033] like Figures 1 to 3 As shown, this embodiment provides a ceiling structure, including a ceiling panel 1 and multiple groups of keel assemblies 2, wherein the ceiling panel 1 is provided with an overlapping portion 11 and an inserting portion 12, the inserting portion 12 is arranged at an angle to the overlapping portion 11 and is connected to each other, and the multiple groups of keel assemblies 2 are arranged at intervals along the length direction of the ceiling panel 1, and each group of keel assemblies 2 includes a connected main keel 21 and a hooking keel 22, the main keel 21 is arranged above the ceiling panel 1 and can be connected and fixed to the ceiling, the hooking keel 22 is provided with a first card slot 221 and a second card slot 222 that are connected to each other, the overlapping portion 11 is at least partially overlapped with the first card slot 221, and the inserting portion 12 is plugged into the second card slot 222.

[0034] In this embodiment, if Figure 1 As shown, the ceiling panel 1 is provided with a plug-in portion 12 and an overlap portion 11 that are arranged at an angle and connected to each other, and the hook keel 22 is provided with a first card slot 221 and a second card slot 222 that are connected to each other. The overlap portion 11 is at least partially overlapped with the first card slot 221, and the plug-in portion 12 is plugged into the second card slot 222. The connection between the ceiling panel 1 and the hook keel 22 is achieved by the two methods of overlap and plug-in cooperation. Compared with the two being connected by only plug-in or overlap, the connection strength and connection reliability are improved. Compared with the prior art that uses multiple sets of buckles to connect the ceiling panel 1 and the hook keel 22, the construction difficulty is reduced and the construction efficiency of the ceiling structure is improved. The plug-in cooperation of the plug-in portion 12 and the second card slot 222 can also reduce the occupied height of the ceiling structure, reduce space waste, and improve the space utilization rate of the ceiling structure. The ceiling panel 1 is connected to the hook keel 22 and the main keel 21 is connected to the hook keel 22, and the structural integrity of the ceiling structure is high. Multiple sets of keel assemblies 2 are spaced apart along the length of the ceiling panel 1 to enhance the overall structural strength of the ceiling structure. In this embodiment, the length of the ceiling panel 1 is perpendicular to the length of the main keel 21, and the first slot 221 is defined along the length of the ceiling panel 1. This description will not be repeated.

[0035] Optionally, the crossbar 22 further includes a mounting slot, through which the main purlin 21 is inserted and abuts against the bottom of the slot. Compared to the prior art method of securing the main purlin 21 to the top surface of the crossbar 22 via multiple connectors, the provision of the mounting slot not only simplifies the vertical positioning of the main purlin 21 and the crossbar 22, but also reduces the overall height occupied by the ceiling structure, thereby enhancing the versatility of the ceiling structure in construction operations with limited floor heights.

[0036] Specifically, if Figure 2 and Figure 3 As shown, the ceiling structure also includes a reinforcement member 4. One end of the reinforcement member 4 extends through the top surface of the hook purlin 22, penetrates the main purlin 21, and locks with the wall of the mounting slot. The reinforcement member 4 improves the connection strength and reliability between the main purlin 21 and the hook purlin 22. The reinforcement member 4 can be a bolt or rivet, etc. It is understood that the mounting slot is provided along the length of the hook purlin 22, and the length of the hook purlin 22 is consistent with the length of the main purlin 21. Further details will not be given.

[0037] In this embodiment, the angle between the plug-in portion 12 and the overlap portion 11 is greater than 90° and less than 180°, and the second slot 222 is located below the first slot 221, that is, the plug-in portion 12 and the overlap portion 11 are arranged at an obtuse angle. Under the action of gravity, the plug-in portion 12 can naturally abut the groove wall on the lower side of the first slot 221, reducing the risk of the plug-in portion 12 being dislodged under the action of gravity or external forces, and improving the vertical pull-out resistance and connection stability of the ceiling panel 1 and the hooking keel 22. In other embodiments, the angle between the plug-in portion 12 and the overlap portion 11 can also be less than 90°, and the second slot 222 can be located above the first slot 221. The first slot 221 supports the overlapping portion 11 upward, and the upper slot wall of the second slot 222 produces downward pressure on the plug-in portion 12. The first slot 221 and the second slot 222 can achieve a limiting effect on the plug-in portion 12 and the overlapping portion 11, and can effectively limit the horizontal displacement of the ceiling panel 1, and enhance the horizontal shear resistance of the ceiling panel 1 and the hooking keel 22.

[0038] The ceiling structure may also include a locking member 3, one end of which is locked to the groove wall of the first slot 221 via the main keel 21 and the overlap portion 11 in sequence, and the other end is pressed against the top surface of the hook keel 22. The provision of the locking member 3 can limit the relative displacement of the main keel 21, the overlap portion 11, and the hook keel 22 in the vertical and horizontal directions, thereby enhancing the connection reliability between any two of the main keel 21, the overlap portion 11, and the hook keel 22, and improving the overall connection strength of the ceiling structure. The locking member 3 can be a locking bolt or a pin, etc. It is understandable that when the plug-in portion 12 and the overlap portion 11 form an acute angle, one end of the locking member 3 can be locked to the groove wall of the first slot 221 via the main keel 21, the plug-in portion 12, and the overlap portion 11 in sequence, thereby improving the connection strength and structural integrity of the main keel 21, the ceiling panel 1, and the hook keel 22.

[0039] Optionally, the ceiling panel 1 is provided with an escape notch 13, through which the hooking keel 22 can slide to a preset position along the length of the ceiling panel 1 through the escape notch 13. The provision of the escape notch 13 facilitates the adjustment of the installation position of the hooking keel 22 by construction personnel. Compared to installing the hooking keel 22 after precise measurement and alignment, the accuracy requirements for the initial installation position of the hooking keel 22 are reduced, thereby improving installation convenience. It should be noted that the preset position of the hooking keel 22 needs to be determined by construction personnel according to the installation specifications of different ceilings in actual construction scenarios, and will not be explained in detail here.

[0040] Preferably, a chamfer 223 is provided on the side of the hooking keel 22 away from the bottom of the first slot 221 along the length direction of the main keel 21 to avoid stress concentration at the overlap between the overlapping portion 11 and the slot wall of the first slot 221. The provision of the chamfer 223 can extend the service life of the hooking keel 22.

[0041] Specifically, the material of the ceiling panel 1 includes aluminum. Compared with materials such as stone or ceramic tiles, the density of aluminum is lower. The weight of the ceiling panel 1 including aluminum is lighter under the same area, which improves the installation convenience and reduces the load-bearing requirements at the connection between the main keel 21 and the ceiling. It can also improve the processing convenience. In addition, aluminum has excellent fire resistance and can improve the overall fire protection effect of the ceiling panel 1.

[0042] For example, the ceiling panel 1 can be a corrugated aluminum plate, and the overlap portion 11 and the plug-in portion 12 provided on the ceiling panel 1 can be processed by a roll-pressed cold bending process. The plug-in portion 12 can be processed into an inclined plate shape, which itself has good guiding performance. The plug-in portion 12 and the second slot 222 are relatively easy to plug into, and the connection and fixing process of the ceiling panel 1 and the hook keel 22 is simple and easy to implement. The plug-in portion 12 can also be processed into an arc plate shape to increase the contact area between the plug-in portion 12 and the hook keel 22, effectively disperse the local stress at the connection between the plug-in portion 12 and the hook keel 22, and improve the connection reliability of the ceiling structure. It is understandable that the shapes of the plug-in portion 12 and the second slot 222 are always adapted to each other, and the plug-in portion 12 can abut against the bottom of the second slot 222 to increase the contact area between the plug-in portion 12 and the hook keel 22, thereby facilitating the load transfer between the hook keel 22 and the ceiling panel 1.

[0043] Specifically, the ceiling panel 1 is provided with an anti-corrosion and anti-fouling layer to enhance the anti-corrosion and anti-fouling capabilities of the ceiling panel 1 and enhance the versatility of the ceiling structure in humid or dirty environments.

[0044] Optionally, the ceiling structure includes a plurality of rigid hangers, which are spaced apart along the length of the main keel 21. The main keel 21 can be connected to the ceiling via the plurality of rigid hangers. The plurality of rigid hangers can share the load with the main keel 21 to prevent local overload of the main keel 21. The rigid hangers can be galvanized steel bars or wire hangers. In order to disperse the load and provide a decorative effect for the main keel 21, the ceiling structure can include a plurality of interconnected ceiling panels 1, which are spaced apart along the length of the main keel 21.

[0045] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
