Description

Technical Field

[0001] The invention relates to the technical field of suspended ceiling structures, in particular to a suspended ceiling structure with earthquake resistance. Background Art

[0002] With the development of social economy, various public buildings and residential buildings are growing rapidly. In order to create a comfortable and beautiful indoor environment, the proportion of suspended ceilings is also increasing.

[0003] Traditional ceiling structures are usually made of aluminum alloy or steel, and then directly fixed to the ceiling structure of a specific building through mechanical parts such as bolts and hooks. Although this type of ceiling is easy to install, it is fragile to vibration. When encountering strong vibrations under conditions such as earthquakes and explosions, the ceiling structure is prone to breakage and falling off, which in turn poses a serious threat to the safety of people and indoor property.

[0004] To improve this defect, some scholars and enterprises began to study the seismic structure design of suspended ceilings. As early as the 1980s, Japanese scholars designed a suspended ceiling with a spring shock-absorbing mechanism that can buffer small vibrations. Later, in the mid-1990s, other scholars used sliding tracks and buffers to realize a seismic structure that produces displacement in the suspended ceiling. These two suspended ceiling technologies have improved the ability of suspended ceilings to resist vibrations to varying degrees.

[0005] However, both cannot select different anti-seismic modes according to different earthquake sensations, and thus both have great limitations in anti-seismic performance. Therefore, there is an urgent need for a ceiling structure that can select different anti-seismic modes according to different earthquake sensations to increase anti-seismic capabilities. Summary of the invention

[0006] The object of the present invention is to provide a seismic-resistant suspended ceiling structure to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0047] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] Figure 1-6 The structure diagram of an embodiment of the present invention having a seismic-resistant ceiling structure is shown in FIG. Figure 1 - Figure 3 The present embodiment provides a seismic-resistant ceiling structure. The purpose of the present invention is to provide a seismic-resistant ceiling structure to solve the problems raised in the above-mentioned background technology.

[0049] In order to solve the above technical problems, the present invention provides the following technical solutions: comprising:

[0050] The connecting plate 100 with grooves on the surface can be connected to the ceiling at the opposite side of the grooves, and the first anti-seismic mechanism is arranged in a circular array in the grooves of the connecting plate 100;

[0051] Among them, the first seismic resistance mechanism is an elastically deformable mechanism, which can absorb vibration energy through deformation after being subjected to vibration energy, and a plurality of first seismic resistance mechanisms are adopted during design, which can disperse the stress to a larger area, reduce single-point force, and prevent structural damage.

[0052] The starting disk 200 is arranged in the groove of the connecting disk 100 and can contact with the first anti-seismic mechanism. The second buffer mechanism includes a moving end and a connecting end. The moving end is connected to the groove of the connecting disk 100, and the connecting end is connected to the wall. The moving end and the connecting end are mutually sleeved and can undergo relative displacement. The hook 300 is arranged on the moving end in a circular shape, and one end can be connected to the connecting end, and the other end can be inserted into the starting disk 200. The moving end is connected to the groove of the connecting disk 100, and the connecting end is connected to the wall. The moving end and the connecting end are mutually sleeved and can undergo relative displacement. The mobile end uses the hook 300 to keep the positions of the moving end and the connecting end relatively stable. When the first anti-seismic mechanism is deformed, it will hit the starting disk 200, and finally the starting disk 200 will be separated from the surface of the hook 300, and then the hook 300 will be separated from the surface of the connecting end, eliminating the restriction between the two, allowing the moving end and the connecting end to displace under the action of vibration and gravity, thereby reducing the stress concentration caused by the rigid connection, thereby reducing damage.

[0053] Specifically, the first anti-vibration mechanism includes:

[0054] The carrying frame 401 is disposed in the groove of the connecting plate 100, and the sleeve 402 is disposed on the surface of the carrying frame 401, wherein a hole is provided at the connection portion between the carrying frame 401 and the sleeve 402, and the hole will not block the movement of the hammer rod 404;

[0055] The friction block 403 is arranged on the inner circumference of the sleeve 402. When the hammer rod 404 moves due to vibration, it will drive the friction block 403 to move in the sleeve 402, thereby converting kinetic energy into heat energy, thereby reducing the vibration amplitude.

[0056] The hammer rod 404 is disposed on the friction block 403, and the counterweight block 405 is disposed at the end of the hammer rod 404 away from the bearing frame 401;

[0057] The counterweight block 405 increases the inertia of the hammer rod 404 , thereby making the impact generated by the hammer rod 404 greater, thereby assisting the hammer rod 404 in hammering the start disk 200 .

[0058] One end of the spring 406 is arranged on the outer peripheral side of the sleeve 402, and the other end is connected to the counterweight 405. With the help of the spring 406, the counterweight 405 has a tendency to return to its original position, so that it can be reused.

[0059] Specifically, the moving end of the second buffer mechanism includes:

[0060] The connecting rod 407 is arranged in the groove of the connecting disk 100, the truncated cone-shaped supporting block 408 is arranged at the end of the connecting rod 407 away from the connecting disk 100, and the wavy friction plate 409 is arranged in a circular array on the outer peripheral side of the supporting block 408, and there is a gap between adjacent friction plates 409, so that when the connecting disk 100 drives the connecting rod 407 to move downward, the friction plate 409 will contact with the locking disk 501. During the contact process, due to its overall truncated cone shape, the contact area will gradually increase, thereby gradually slowing down its falling speed, thus avoiding sudden falling and sudden stopping to cause secondary damage to the ceiling. Moreover, due to its wavy shape and the gap between adjacent friction plates 409, the friction plate 409 has space to deform with the help of the gap. When deformation occurs, its wavy shape increases the length of a single friction plate 409, so that the more it moves to the end, the more friction plates 409 are stacked, and the displacement speed caused by vibration can be better slowed down, thereby completing the buffering.

[0061] The lifting plate 410 is arranged on the outer peripheral side of the connecting rod 407 and is connected to the hook 300; the hook is connected to the connecting rod 407 with the help of the lifting plate 410. This design will prevent the bottom of the hook 300 from generating pulling force on the starting plate 200, thereby minimizing the impact of external forces on the starting plate 200.

[0062] Specifically, the connection end of the second buffer mechanism includes:

[0063] The locking plate 501 is arranged on the outer peripheral side of the connecting rod 407 , and the hanging hook 502 is connected to the locking plate 501 through the vertical rod 503 . The hanging hook 502 is connected to the whole by means of the locking plate 501 and the vertical rod 503 .

[0064] Specifically, the start disk 200 is arranged on the outer peripheral side of the connecting rod 407, and a plurality of inclined grooves 600 are arranged on the start disk 200 in a circular array. The hook 300 is provided with an inclined surface near the end of the start disk 200, and the inclined surface groove 600 and the inclined surface can contact each other. The hook 300 is provided with an arc-shaped elastic sheet 700 near the end of the start disk 200, and the bottom surface of the start disk 200 is provided with a slot 800 for inserting the arc-shaped elastic sheet 700. When the inclined surface groove 600 squeezes the inclined surface of the hook 300, the hook 300 will rotate toward the locking disk 501, and then buckle on the surface of the locking disk 501, so as to realize the connection between the connecting rod 407 and the locking disk 501, and the arc-shaped elastic sheet 700 is inserted into the slot 800, and with the help of its elastic force, the start disk 200 can maintain the squeeze state of the hook 300 when it is not subjected to a large external force.

[0065] Specifically, the maximum outer diameter of the support block 408 is greater than the inner diameter of the locking disk 501, so that when the descending speed is too fast and the length is too long, the support block 408 can cooperate with the locking disk 501 due to its own length to forcibly prevent it from falling.

[0066] Specifically, a blocking piece 900 is provided on the outer peripheral side of the connecting rod 407 to block the movement of the start disk 200. The blocking piece 900 limits the moving path of the start disk 200, thereby ensuring that the arc-shaped elastic piece 700 can be inserted into the slot 800 at the best angle.

[0067] Specifically, the hook 300 is connected to the lifting plate 410 via the spiral spring shaft 1000, so that the hook 300 has a tendency to return to its original position with the help of the spiral spring shaft 1000.

[0068] When using:

[0069] When the whole is in use, the whole device is first connected to the wall with the help of the hanging hook 502. After the connection, the whole device is connected to the ceiling with the help of the connecting plate 100. At this time, when a slight vibration occurs, the vibration will drive the counterweight block 405 and the hammer rod 404 on its surface to move back and forth in the sleeve 402. At this time, the vibration will be dispersed and buffered. When the vibration amplitude is too large, the hammer rod 404 will hammer the starting disk 200. When multiple hammer rods 404 hammer the starting disk 200, they will overcome the elastic force of the arc-shaped elastic sheet 700 and then detach from the surface of the starting disk 200, so that the starting disk 200 will not restrict the hook 300, and then the hook 300 will detach from the surface of the locking disk 501 under the action of the vibration, releasing the part including the connecting disk 100, and the connecting rod 407 moves downward under the action of gravity, and is further buffered with the help of the friction plate 409, thereby completing the anti-seismic buffering.

[0070] Beneficial effects:

[0071] The first anti-seismic mechanism can effectively absorb and consume vibration energy, reduce the impact of vibration on the ceiling, and improve the anti-seismic performance. The design of multiple first anti-seismic mechanisms can disperse stress and prevent single-point damage.

[0072] The second buffer mechanism can achieve relative displacement between the moving end and the connecting end, cut off the rigid connection in the event of a strong earthquake, avoid damage caused by stress concentration, and play a buffering and protective role. The wavy friction plate design can further slow down the falling speed and reduce secondary injuries.

[0073] The hook mechanism is designed to maintain a stable connection between the ceiling and the wall under normal circumstances, and automatically releases and switches to buffer mode when a strong earthquake occurs.

[0074] The design of the counterweight block, spring, etc. enhances the effect of the first anti-vibration mechanism; the matching of the bearing block and the locking plate can forcibly prevent the falling; the design of the blocking piece, etc. improves the overall working performance.

[0075] The entire ceiling has a dual insurance design concept of earthquake resistance and buffering, which can effectively protect the ceiling from earthquake damage, improve safety and service life, and reduce maintenance costs.

In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
