[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] In the following description, unless otherwise expressly specified and limited, the terms "setup," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection, etc. Those skilled in the art can understand the specific meaning of the above terms in this technical solution according to the specific circumstances.

[0022] This utility model is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of this utility model. The specific technical features described in the following specific embodiments can be combined in any suitable manner without contradiction, and such combinations should also be considered as part of the disclosure of this utility model, provided they do not violate its spirit.

[0023] See Figures 1-4 This utility model provides an earthquake-resistant and detachable ceiling structure, including a main keel 1 and an earthquake-resistant device. Triangular keels 2 are connected to both sides of the main keel 1, and they can be connected by means of integral connection, bolt connection, welding, or bonding. An L-shaped connecting seat 3 is detachably connected to the opposing side of the triangular keels 2 via a knob 4 (which can be a knob bolt). That is, the L-shaped connecting seat 3 is tightened and fixed to the side of the triangular keel 2 by the knob bolt. A ceiling panel 15 overlaps on the L-shaped connecting seat 3. The earthquake-resistant device includes a top plate 17, under which a movable component 10 is connected to the bottom of the top plate 17 via a spring 6. A fixed component 11 is slidably connected inside the movable component 10, and the outer periphery of the movable component 10 and the outer periphery of the fixed component 11 are connected by an elastic arc plate 14. The top plate 17 of the earthquake-resistant device is connected to the main keel 1 by bolts 5. After connection, the fixed component of the earthquake-resistant device can be vertically overlapped on the ceiling panel 15.

[0024] In some embodiments, see Figure 5The movable component 10 is slidably connected to a fixed component 11. Specifically, the movable component 10 has a movable cavity 101 and an annular flange 102 disposed at the end of the side wall of the movable cavity 101. The fixed component 11 includes a cylinder 110 and a cylindrical top plate 111 disposed on the cylinder. The cylinder 110 and the cylindrical top plate 111 are both accommodated in the movable cavity 101, and when the cylindrical top plate 111 slides to the end of the movable cavity 101, it can overlap the annular flange 102, so that the cylindrical top plate 111 is not easy to fall off from the movable cavity 101.

[0025] In some embodiments, the outer periphery of the movable component 10 and the outer periphery of the fixed component 11 are connected by elastic arc plates 14. Specifically, the movable component 10 is provided with a cylindrical support 8, and the fixed component 11 is provided with a cylindrical base 12. Multiple vertically corresponding mounting holes 9 are evenly arranged around the outer periphery of both the cylindrical support 8 and the cylindrical base 12. The two ends of the multiple elastic arc plates 14 extend into these vertically corresponding mounting holes 9, and are fixedly connected to the cylindrical support 8 and the cylindrical base 12 by welding, plug-in connection, riveting, or bonding, to ensure that the elastic arc plates 14 can be firmly installed in the mounting holes 9. Furthermore, the top plate 17 is connected to the cylindrical support 8 via a spring 6, while the cylindrical base 12 can be vertically attached to the ceiling panel 15.

[0026] Furthermore, a padding layer 13 is provided under the cylindrical base 12. When the cylindrical base 12 is vertically attached to the ceiling panel 15, the padding layer 13 is in direct contact with the ceiling panel 15. At the same time, in order to prevent the spring 6 from rusting due to excessive contact with air, a protective sleeve 7 is also provided between the top plate 17 and the cylindrical support 8, and the spring 6 is located inside the protective sleeve 7.

[0027] In some embodiments, the cylindrical support 8 and the cylindrical base 12 are located on the same axis and have the same diameter. This design not only enhances the stability and load-bearing capacity of the seismic device, but also ensures the smooth sliding between the movable component 10 and the fixed component 11. At the same time, this design allows the elastic arc plate 14 to maintain a consistent contact force and tight fit when connected with the cylindrical support 8 and the cylindrical base 12, and the tension distribution is uniform.

[0028] In some embodiments, see Figure 3The system also includes a T-shaped overlap joint 16, which connects to both ends of the ceiling panel 15. The T-shaped overlap joint 16 is embedded in the groove 31 of the L-shaped connector 3 and overlaps onto the L-shaped connector 3. The groove 31 provides precise positioning and guidance for the T-shaped overlap joint 16, making the overlapping process smoother and more accurate. Simultaneously, the tight fit between the groove 31 and the T-shaped overlap joint 16 enhances the stability and firmness of the connection, effectively preventing the ceiling panel 15 from loosening or falling off during use. Furthermore, after the T-shaped overlap joint 16 is embedded in the reserved groove of the L-shaped connector 3, it ensures that the ceiling panel 15 and the L-shaped connector 3 are on the same horizontal plane, making the entire ceiling system flatter and more aesthetically pleasing. To further enhance the decorative effect of the ceiling system, decorative surfaces can be applied to the bottom surface of the triangular keel 2 and the bottom surface of the L-shaped connector 3.

[0029] Operating steps:

[0030] Install the seismic device: First, connect the top plate 17 of the seismic device to the main keel 1 with bolts 5 to ensure that it is vertical under the action of gravity.

[0031] Connecting the L-shaped connector: Lay the L-shaped connector 3 flat, and then use the knob 4 to connect the triangular keel 2 to the L-shaped connector 3.

[0032] Install the ceiling panel: Insert the T-shaped joints 16 at both ends of the ceiling panel 15 into the grooves 31 of the L-shaped connector 3, so that the ceiling panel 15 is stably attached to the L-shaped connector 3. At this time, the padding layer 13 at the lower end of the fixing component 11 of the seismic device naturally rests on the ceiling panel 15. The seismic device not only supports the keel, but also resists external forces.

[0033] When it is necessary to disassemble and replace the ceiling panel, first push the ceiling panel 15 upward. At this time, the anti-vibration device can be displaced upward due to the action of the spring 6 and the movable component 10. Then, rotate the knob 4 until the L-shaped connecting seat 3 is rotated to 90°, so that the ceiling panel 15 can be moved downward and disassembled smoothly.

[0034] The function of the anti-vibration device is as follows: During installation and disassembly, thanks to the ingenious design of the spring 6 and the sliding connection between the movable component 10 and the fixed component 11, the anti-vibration device can freely extend and retract. When subjected to external forces, the ceiling panel 15 will shake, and the anti-vibration device can effectively unload these external forces. Specifically, the movable component 10 and the fixed component 11 are connected by a sliding connection. Once subjected to external forces, the cylindrical top plate 111 of the fixed component will rub against the side wall of the movable cavity 101 of the movable component 10, generating heat and consuming some energy. At the same time, the elastic arc plate 14 will bend outward, working in conjunction with the friction to quickly eliminate the vibration energy. When the cylindrical top plate 111 slides to the end of the movable cavity 101, it will overlap the annular flange 102, thereby playing a limiting role and further preventing the fixed component 11 from falling off the movable component (the connection between the elastic arc plate and the cylindrical support 8 on the movable component 10 and the cylindrical base 12 on the fixed component 11 can also prevent the fixed component 11 from falling off the movable component 10). In addition, the protective sleeve 7 can also move up and down with the spring 6, and has good deformation and recovery capabilities.

[0035] Through the above methods, this utility model provides a seismic-resistant and removable ceiling structure that is not only easy to operate and install, but also improves the seismic performance of the ceiling, preventing the ceiling panel 15 from loosening and falling, which could pose a fatal risk to people indoors. The overlapping form of the ceiling panel 15 also facilitates installation and disassembly, greatly reducing manpower. Compared with existing technologies, this utility model optimizes both disassembly and installation as well as seismic resistance, avoiding the need for tools to remove ceiling panels and greatly improving seismic safety performance. It also facilitates future maintenance.
