Description

Technical Field

[0001] This utility model relates to the field of keel technology, specifically a light steel keel reinforcement structure for earthquake resistance in integrated suspended ceilings for audio-visual rooms. Background Technology

[0002] With the popularization of audio-visual entertainment systems, the functional requirements of modern home theaters for suspended ceilings are becoming increasingly complex. On the one hand, suspended ceilings need to integrate components such as lighting equipment, acoustic materials, and cable conduits, which increases the load. On the other hand, the low-frequency vibrations generated by audio-visual equipment (such as subwoofers and surround sound systems) during operation, as well as the loads under earthquake action, can easily lead to deformation of traditional light steel keel structures, loosening of connectors, or even ceiling collapse, threatening equipment safety and personnel safety.

[0003] A Chinese patent discloses a 3D ceiling panel keel reinforcement device (authorization announcement number CN221989694U). This patented technology includes:

[0004] By designing the fixing components, firstly, an adjustment groove is provided at the adjustment point of the first fixing screw, which allows for auxiliary adjustment of the first fixing screw, avoiding the problem of being unable to adjust after damage to the first fixing screw; secondly, the elastic compression of the adjusting block by the helical spring increases the frictional resistance when the second fixing screw rotates, reducing the probability of the second fixing screw loosening and ensuring the stability of the fixation; thirdly, the locking screw further reduces the probability of the second fixing screw loosening, resulting in high stability.

[0005] With the addition of auxiliary components, when the second fixing screw is rotated to lock, the seat body can be moved upward simultaneously. Under the compression of the seat body, the fixing strength between the two fixing rods and the keel can be achieved, making the fixing more stable.

[0006] However, it has certain drawbacks: although it improves static stability through a triple anti-loosening mechanism (adjusting groove loss tolerance design, spring pre-tightening friction constraint, and locking screw auxiliary fixation), it does not introduce dynamic energy dissipation mechanisms for low-frequency vibration and seismic loads; the rigid connection nodes it relies on lack viscoelastic damping layers or hydraulic buffer devices, which leads to accelerated fretting wear under cyclic vibration, attenuation of pre-tightening force, inability to dissipate multi-directional vibration energy, and easy to cause structural instability when coupled at resonant frequencies, ultimately causing keel deformation or even overall collapse, making it difficult to meet high usage requirements. Utility Model Content

[0007] The purpose of this utility model is to provide a light steel keel reinforcement structure for earthquake resistance of integrated suspended ceilings in audio-visual rooms, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A light steel keel reinforcement structure for earthquake resistance of integrated suspended ceiling in audio-visual room includes a C-shaped base. The upper ends of the front and rear surfaces of the C-shaped base are fixed with support plates, and the front and rear ends of the interior of the C-shaped base are provided with clamping mechanisms.

Two rotating blocks are symmetrically fixed to the upper surface of each of the two sliders. A rotating rod is rotatably connected to the interior of each of the two rotating blocks. Rotating blocks are rotatably connected to the upper end of the front and rear surfaces of the rotating rod.

Rubber blocks are fixed to both the upper and lower surfaces of the connecting block, and rubber plates are fixed to the opposite surfaces of the two connecting plates.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes an integrated anti-seismic mechanism consisting of a sliding rod, a slider, a spring, and rubber damping components (rubber blocks and rubber plates) to significantly improve seismic performance while ensuring the lightweight and acoustic vibration isolation performance of the suspended ceiling. The spring provides flexible buffering to absorb vibration energy, the slider slides along the sliding rod to precisely guide the vibration direction, and the nonlinear friction damping of the rubber blocks and rubber plates can quickly dissipate lateral impacts, suppress low-frequency resonance and structural rebound, and enable the C-shaped base and internal keel to stabilize rapidly after vibration, avoiding the risk of stress concentration or detachment caused by rigid connections in traditional suspended ceilings.

[0023] Please see Figure 1 and Figure 2 In this embodiment of the utility model, a light steel keel reinforcement structure for earthquake resistance of an integrated suspended ceiling in an audio-visual room includes a C-shaped base 1. Support plates 2 are fixedly connected to the upper ends of the front and rear surfaces of the C-shaped base 1. Clamping mechanisms 3 are provided at both the front and rear ends of the interior of the C-shaped base 1. The clamping mechanism 3 includes a clamping plate 4. The clamping plate 4 is located inside the C-shaped base 1. A threaded rod 5 is rotatably connected to one side surface of the clamping plate 4. The threaded rod 5 is threaded through and connected to one side surface of the C-shaped base 1. Support rods 6 are fixedly connected to the left and right sides of the threaded rod 5 on one side surface of the clamping plate 4. The support rods 6 movably pass through one side surface of the C-shaped base 1.

[0024] The ceiling joists for the home theater are placed inside the C-shaped base 1. Rotating the threaded rod 5 can move the clamping plate 4 back and forth, which is used to clamp and fix the ceiling joists for the home theater.

[0025] exist Figure 1 , Figure 3 and Figure 4 In the middle: The lower surface of the support plate 2 is provided with an anti-seismic mechanism 7, which includes a C-shaped plate 8 located outside the support plate 2. The lower inner surface of the C-shaped plate 8 is fixedly connected to a slide block 9. The left and right inner surfaces of the slide block 9 are jointly fixedly connected to a slide rod 10. Two sliders 11 are symmetrically slidably connected to the outside of the slide rod 10. The sliders 11 are slidably connected to the inside of the slide block 9. Springs 12 are fixedly connected to the opposite side surfaces of the two sliders 11. One end of the spring 12 is fixedly connected to one inner surface of the slide block 9. Two rotating blocks 13 are symmetrically fixed to the upper surfaces of the two sliders 11. A rotating rod 14 is rotatably connected inside the two rotating blocks 13. Rotating blocks 15 are rotatably connected to the upper ends of both the front and rear surfaces. The upper ends of rotating blocks 15 are fixed to the lower surface of the support plate 2. Sliding holes 16 are provided on both the front and rear surfaces of the slide block 9 at the positions opposite to the slider 11. A damping element 17 is provided inside the sliding hole 16. The damping element 17 includes a connecting block 18 and connecting plates 19 located on the upper and lower sides of the connecting block 18. The connecting block 18 is slidably connected to the inside of the sliding hole 16 and is fixed to one side surface of the slider 11. Rubber blocks 20 are fixed to both the upper and lower surfaces of the connecting block 18. Rubber plates 21 are fixed to the opposite side surfaces of the two connecting plates 19. The rubber blocks 20 are movably attached to the rubber plates 21.

[0026] The entire keel reinforcement structure is fixed to the top of the wall through the upper end of the C-shaped plate 8. Bolts can pass through the upper end of the C-shaped plate 8 for fixing.

[0027] When the entire keel vibrates, the C-shaped seat 1 will continuously press down the rotating rod 14, causing the slider 11 to continuously compress the spring 12. During this process, the connecting block 18 moves left and right with the slider 11, and the rubber block 20 continuously rubs against the rubber plate 21, which plays a damping role, so that the spring 12 can quickly stabilize, thereby making the C-shaped seat 1 and the internal audio-visual room ceiling keel quickly stabilize, achieving good anti-vibration performance.

[0028] The rubber plate 21 exerts a certain compressive force on the rubber block 20, resulting in good damping performance.

[0029] The working principle of this utility model is as follows: During installation, the C-shaped plate 8 is first fixed to the top of the wall with bolts. Then, the ceiling keel of the audio-visual room is embedded into the C-shaped seat 1. The clamping plate 4 is driven to move back and forth by rotating the threaded rod 5. With the guidance of the support rod 6, the keel is clamped and fixed. During the vibration reduction process, when external vibration (such as acoustic vibration) is transmitted to the structure, the C-shaped seat 1 is subjected to load and presses down the rotating rod 14, forcing the slider 11 to slide along the sliding rod 10 to both sides and compress the spring 12. At the same time, the connecting block 18 drives the rubber block 20 to move laterally in the sliding hole 16, generating frictional damping with the rubber plate 21 on the connecting plates 19 on both sides. The squeezing friction between the rubber block 20 and the rubber plate 21 can quickly consume the vibration energy and suppress the reciprocating oscillation of the spring 12, thereby reducing the transmission of vibration to the ceiling keel and finally achieving rapid stabilization of the C-shaped seat 1 and the internal keel.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
