[0001] The present invention relates to the technical field of construction work and building construction, and particularly to a novel low-damage ceiling system.

Background Art

[0002] In earthquake-prone areas, conventional ceiling systems usually cannot provide sufficient earthquake protection, resulting in structural damage and potential harm to occupants. Existing systems typically use rigid joint suspension bundles, lacking the necessary flexibility and energy dissipation capacity to effectively handle seismic forces.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The object of the present invention is to provide a novel low-damage ceiling system that improves the seismic performance of the ceiling and enhances safety and resilience during earthquakes, in order to overcome the drawbacks existing in the above prior art.

Means for Solving the Problems

[0004] The present invention provides a novel low-damage ceiling system, including friction dampers and vibration isolation suspension bundles. The friction dampers are located at the connection points of the ceiling grid frame, dissipate seismic energy, prevent joint damage, and can self-align the ceiling grid frame after an earthquake. The friction dampers include connecting arms and torsion springs. The connecting arms are connected to the bottom plate via pivot bolts, absorb seismic energy through scissor-like motion, and the torsion springs are concentrically mounted around the lower part of the pivot bolts. The torsion springs are used to self-align the arms after the seismic force dissipates. The vibration isolation suspension bundles support the ceiling grid, filter stronger vibration frequencies, and are used to provide rotational flexibility during seismic activity. The vibration isolation support system comprises a top support, an isolation member, a radial spring, a conventional spring, and a bottom support. The top support is connected to the building's structural slab, and a cylindrical assembly is provided at the end of the top support. The radial spring is positioned around the cylindrical assembly and returns to its central position after seismic displacement. A conventional spring beneath the radial spring is used to support the bottom support and further filter vibrations. The radial spring is designed for this system to provide significant vibration isolation, return the support assembly to its position after an earthquake, and enhance ceiling stability.

[0005] Furthermore, the bottom plate is attached to the ceiling structure in order to maintain the position of the damper.

[0006] Furthermore, the base plate consists of two rectangular plates and serves as the mounting point for the entire assembly.

[0007] Furthermore, the pivot bolt is provided with a nut and a washer, which withstand the applied force and ensure the stability of the assembly, while the fastener fixes the bolt in place.

[0008] Furthermore, the aforementioned ceiling lattice frame consists of four ceiling panels.

[0009] Furthermore, each of the aforementioned ceiling panels has dimensions of 600mm x 600mm.

[0010] Furthermore, the pivot bolts are used as pivot points at both ends of the connecting arm.

[0011] Furthermore, the bottom suspension beams provide vertical support and also contribute to the vibration isolation process, transmitting filtered vibration energy from the isolation members to the ceiling, ensuring the overall stability and elasticity of the ceiling system.

[0012] Furthermore, the top support beam is connected to the building's structural panel, and the isolation member is supported by anchoring the upper part of the top support beam.

[0013] Furthermore, the cylindrical assembly at the end of the top suspension bundle moves within the radial spring, and this movement is counteracted by returning the cylindrical assembly to its original position.

[0014] The operating principle of the present invention is as follows: The friction damper operates like scissors, moving with the extension and retraction of the connecting arm to absorb and dissipate energy. When subjected to earthquakes or lateral forces, the connecting arm rotates around the pivot bolt at its end. Friction between the moving parts and resistance from the torsion spring dissipate energy and reduce the effects of vibration. The torsion spring is located beneath the nut, ensuring it is concentric with the pivot bolt, and its end is fixed to the spring arm. As the connecting arm rotates, the torsion spring is wound and unwound, generating a restorative force. After the force is removed, the torsion spring returns the connecting arm to its original position, ensuring the friction damper is ready for subsequent movement. Mechanical friction occurs between the pivot joint and the surface, absorbing kinetic energy. The torsion spring also serves as damping, providing a force to return to a controlled starting position by resisting sudden movements. During seismic activity, the top suspension bundle transmits vibrational energy to the isolation member. The cylindrical assembly at the end of the top suspension bundle moves within the radial spring, counteracting the movement by returning the assembly to its original position. Simultaneously, the conventional spring further absorbs and filters vibrations, significantly reducing their impact on the bottom suspension bundle and ceiling structure. Such a double-spring mechanism is crucial for maintaining ceiling integrity during and after earthquakes. [Effects of the Invention]

[0015] Compared to the prior art, the present invention has the following beneficial effects. 1. Enhance the seismic resistance of the ceiling, providing high safety and resilience. In this invention, the low-damage ceiling system can more effectively prevent the effects of natural disasters such as earthquakes, reduce damage, and recover quickly after impact, ensuring the safety of personnel and the normal use of the building. It strengthens structural integrity during earthquakes by preventing joint damage and filtering strong vibration frequencies. Friction dampers are used for energy dissipation and self-centering, and vibration isolation suspension bundles are used for vibration filtering.

[0016] 2. Wide range of applications. In this application, the overall design of the ceiling system includes friction dampers and improved vibration isolation suspension bundles. The modular layout allows for easy integration into existing buildings and enhances seismic resilience without requiring extensive structural modifications.

[0017] 3. It possesses flexibility and energy dissipation capabilities. In this application, the low-damage ceiling system provides a novel solution to improve the safety of buildings in earthquake events. By integrating friction dampers and vibration isolation suspension bundles, the present invention enhances the resilience of structures and provides assurance of the safety of life and property in earthquake-prone areas.

[0025] In a specific embodiment, the dimensions of each ceiling panel are 600mm x 600mm.

[0026] In a specific embodiment, the pivot bolts 1-3 are used as pivot points at both ends of the connecting arm 1-2.

[0027] In a specific embodiment, the bottom support beam 2-5 provides vertical support and also contributes to the vibration isolation process, transmitting filtered vibration energy from the isolation member 2-2 to the ceiling, thereby ensuring the overall stability and elasticity of the ceiling system.

When subjected to earthquakes or lateral forces, the connecting arm 1-2 rotates around the pivot bolt 1-3 at its end. Friction between the moving parts and resistance from the torsion spring 1-4 dissipate energy and reduce the effects of vibration.

Mechanical friction occurs between the pivot joint and the surface, absorbing kinetic energy. The torsion spring 1-4 also serves as damping, providing a force to return to a controlled starting position by resisting sudden movements. During seismic activity, the top suspension beam 2-1 transmits vibrational energy to the isolation member 2-2. The cylindrical assembly at the end of the top suspension beam 2-1 moves within the radial spring, counteracting the movement by returning the assembly to its original position. Simultaneously, the normal spring 2-4 further absorbs and filters vibrations, significantly reducing their impact on the bottom suspension beam 2-5 and the ceiling structure. Such a double-spring mechanism is crucial for maintaining the integrity of the ceiling during and after an earthquake.
