Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a coupling beam damper. Background Technology

[0002] A coupling beam damper is a vibration control device used in building structures. Installed on the coupling beams of a building, it absorbs and dissipates vibration energy caused by earthquakes or strong winds, reducing structural displacement and vibration damage. Coupling beam dampers are typically made of metal steel plates, which, under external vibration conditions, generate tensile or compressive forces on the steel plates to absorb vibration energy.

[0003] However, existing coupling beam dampers are susceptible to steel plate fracture under high-intensity vibrations. Once the steel plates fracture, the beams may detach, leading not only to damping failure but also potentially severely impacting the overall stability of the building structure. Furthermore, the inability to detect fractures between coupling beams in a timely manner poses a safety hazard to the building.

[0004] There is an urgent need for an innovative design of a coupling beam damper to solve the aforementioned fracture problem and improve the safety of buildings under vibration. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a coupling beam damper, comprising:

[0006] An embedded component has two components arranged opposite to each other, including an embedded plate, sleeves arranged on both sides of the embedded plate, and a fixing plate perpendicular to the embedded plate. Reinforcing bars are inserted inside the sleeves. The fixing plate is welded to both the embedded plate and the sleeves. The two fixing plates are at the same height and there is a gap between them.

[0007] A damping plate is connected to two fixed plates. The damping plate has several deformation holes. The fixed plates and the damping plate are connected by several screw holes. Screws pass through the screw holes for fixed connection.

[0008] The gap in the fixed plate also contains a tension support mechanism.

[0009] In some embodiments of this utility model, the deformation hole is located in the gap.

[0010] In some embodiments of this utility model, the deformation hole is rhomboid in shape, and several rhomboids are evenly arranged in the gap, with a stretching area between two adjacent deformation holes.

[0011] In some embodiments of this utility model, the deformation hole is elliptical in shape, and several elliptical holes are evenly arranged in the gap, with a stretching region between two adjacent deformation holes.

[0012] In some embodiments of this utility model, there are at least two damping plates, and the at least two damping plates are respectively disposed on both sides of the fixed plate.

[0013] In some embodiments of this utility model, a disc spring is sleeved at the connection between the screw and the surface of the damping plate.

[0014] In some embodiments of this utility model, a friction plate is provided between the damping plate and the fixing plate.

[0015] In some embodiments of this utility model, the tension support mechanism includes a connecting rod connected to the embedded plate, a tension assembly connected between the two connecting rods, and a ball joint at the connection between the connecting rod and the embedded plate, wherein the ball joint is rotatably connected to the embedded plate.

[0016] In some embodiments of this utility model, the tensioning assembly includes a rack connected to one of the connecting rods and a toothed block connected to another connecting rod. The toothed block can be pulled out and moved relative to the rack. Limiting blocks are evenly arranged on the rack. After the toothed block is pulled out, it is locked with the limiting blocks.

[0017] In some embodiments of this utility model, the rack and the toothed block are further provided with a movable cavity at their initial positions, the toothed block is movably disposed in the movable cavity, the damping plate is disconnected, and the toothed block is pulled into the rack.

[0018] The beneficial effects of this utility model are as follows: This utility model uses a pre-embedded plate, a sleeve, and a fixed plate perpendicular to it.

The damping plate is designed with deformation holes to increase stress dispersion and deformation absorption capabilities, and is firmly connected to the fixed plate through screw holes and screws. Unlike traditional damper structures, this design introduces a tension support mechanism between the pre-embedded plates, providing support and connection functions under normal conditions. Furthermore, in the event of damping plate breakage, its automatic tensioning and locking mechanism provides redundant support and additional safety assurance. This utility model breaks through the limitation of traditional dampers that can only passively withstand vibrations. Through an active connection and support mechanism, it enhances the seismic performance of the building, effectively solves the problem of damping plate detachment after breakage, and provides more efficient vibration control and structural stability.

[0031] like Figures 1 to 7 The connecting beam damper shown includes:

[0032] Embedded component 1: Two components are arranged opposite each other, including an embedded plate 11, sleeves 12 disposed on both sides of the embedded plate 11, and a fixing plate 13 perpendicular to the embedded plate 11. Reinforcing bars are inserted into the sleeves 12. The fixing plate 13 is welded to both the embedded plate 11 and the sleeves 12. The two fixing plates 13 are at the same height, with a gap between them. Figure 1 , Figure 2 As shown, the number of sleeves 12 can be set according to the actual number of reinforcing bars in the construction. The sleeves 12 are fixedly connected to the reinforcing bars, and the sleeves 12 are connected to the embedded plate 11 by welding. Embedded component: 1. When the beam is poured, it is put in in advance to connect the reinforcing bars to the sleeves 12, and then the concrete is poured on top to fix the embedded part to the beam concrete.

[0033] Damping plate 2, such as Figure 1 As shown, the damping plate 2 is connected to two fixed plates 13. Several deformation holes 21 are formed on the damping plate 2, and several screw holes are also formed at the connection between the fixed plate 13 and the damping plate 2. Screws 22 pass through these screw holes for fixed connection. It should be noted that the deformation holes 21 on the damping plate 2 can have various shapes, including circular, rhomboid, elliptical, or other shapes. Furthermore, the arrangement of the deformation holes 21 can also be varied, including matrix, linear, or other arrangements. The thickness and number of damping plates 2 can be calculated and set according to the specific durability and performance requirements. It should also be noted that when there are multiple damping plates 2, they can be distributed on both sides of the fixed plate 13.

[0034] like Figure 1 , Figure 2As shown, a tension support mechanism 3 is also provided in the gap of the fixed plate 13. It should be noted that the tension support mechanism 3 can take many forms, such as a rack 32b, a toothed block 32c, a telescopic link, a sliding pin, or other structures that can achieve this function.

[0035] This invention utilizes a pre-embedded plate 11, a sleeve 12, and a perpendicular fixing plate 13. Reinforcing bars are inserted into the sleeve 12, and the components are welded together to ensure a stable connection and foundation stability under vibration conditions. The damping plate 2 is designed with deformation holes 21 to increase stress dispersion and deformation absorption capabilities, and is securely connected to the fixing plate 13 via screw holes and screws 22. Unlike traditional damper structures, this design introduces a tension support mechanism 3 within the gap of the fixing plate 13. This mechanism provides support and connection under normal conditions, and in the event of damping plate 2 breakage, its automatic tensioning and locking mechanism provides redundant support and additional safety. This invention overcomes the limitation of traditional dampers that can only passively withstand vibrations, enhancing the seismic performance of buildings through active connection and support mechanisms. It effectively solves the problem of damping plate 2 detachment after breakage, providing more efficient vibration control and structural stability.

[0036] like Figure 1 , Figure 5 As shown, deformation holes 21 are formed on the damping plate 2. To maximize the seismic resistance of deformation holes 21, their positions are located in the gaps. This arrangement of deformation holes 21 in the gaps not only optimizes the uniform distribution of structural stress through the shape and arrangement of the holes but also improves deformation absorption efficiency. The design of the holes in the gaps provides an additional elastic zone between the beams, allowing for better absorption of external energy and mitigation of pressure directly transmitted to the fixed plate 13 and the embedded components 1 when the structure is under stress. The deformation holes 21 not only enhance the deformation capacity of the damping plate 2 but also increase the overall structural stability.

[0037] In some embodiments of this utility model, such as Figure 1 , Figure 4As shown, the shape and layout of the holes play a crucial role in enhancing the deformation absorption capacity and stress dispersion effect of the material. The deformation holes 21 are rhomboid in shape, with several rhombuses evenly arranged in the gaps, and a tensile region between two adjacent deformation holes 21. The rhomboid shape of the deformation holes 21 and their even arrangement in the gaps provide an optimized way to reduce stress concentration and improve the tensile and deformation capacity of the area around the holes. The rhomboid holes have excellent directionality and geometric characteristics, which can increase the stress-bearing surface when the structure is under stress, thereby dispersing stress more effectively. By evenly arranging multiple rhomboid holes, a continuous tensile region can be further formed, providing greater elasticity and energy absorption capacity during deformation. The rhomboid holes not only provide a larger surface area to disperse stress in terms of shape, but also create a coherent deformation chain through their arrangement, thereby reducing the risk of material fracture and uneven displacement. The rhomboid layout ensures excellent seismic resistance under extreme conditions, making the structure more resilient and durable.

[0038] In some embodiments of this utility model, such as Figure 5 As shown, the deformation holes 21 are elliptical in shape, with several ellipses evenly arranged in the gaps. The space between two adjacent deformation holes 21 forms a tensile region. The elliptical holes provide a more directional profile, which can more widely disperse compressive stress when the structure is under load, thereby improving the local deformation efficiency. The multiple evenly arranged elliptical holes form interconnected tensile regions, which provide higher energy absorption capacity during deformation, enabling the structure to exhibit greater flexibility under load.

[0039] Traditional damper designs typically employ a single damping plate layout, which can limit the range and efficiency of energy absorption, especially when dealing with complex and multi-directional vibrations. In some embodiments of this invention, such as... Figure 3 As shown, there are at least two damping plates 2, which are respectively arranged on both sides of the fixed plate 13. The symmetrical arrangement of the two damping plates 2 not only increases the total energy absorption area, but also distributes stress more evenly, enhancing the overall seismic resistance. This allows the damping plates 2 on both sides to work together to resist external forces from different directions, thereby improving the dynamic adaptability of the system. The configuration of multiple damping plates 2 provides a stronger vibration reduction effect and effectively reduces the amplitude of vibration transmitted to the fixed plate 13. It also enhances the redundancy of the structure; even if one damping plate 2 fails, the other side can still provide partial support and energy dissipation, increasing the safety and reliability of the system.

[0040] In the seismic and vibration reduction design of building structures, the detailed optimization of connecting components is of great significance for improving the durability and vibration absorption capacity of the structure. Traditional connection methods are often simple and direct, such as directly fixing the damping plate 2 with a screw 22. However, under high-intensity or long-term vibration, this may lead to stress concentration or loosening of the screw 22, thus affecting the stability of the overall structure. In some embodiments of this utility model, a disc spring is sleeved at the connection between the screw 22 and the surface of the damping plate 2. The disc spring is a mechanical component with excellent elastic properties. Its unique shape design allows it to absorb impact energy through elastic deformation when subjected to external forces, effectively dispersing the concentrated stress at the screw 22 and reducing connection loosening and fatigue damage caused by vibration. Compared with the traditional direct connection with the screw 22, the disc spring provides additional elastic buffer at the connection, enabling the structure to exhibit higher stability and seismic resistance when facing vibration or impact. The disc spring not only enhances the vibration dissipation effect but also offsets connection displacement or thermal expansion and contraction caused by environmental changes, ensuring long-term safety and reliability of the connection.

[0041] In some embodiments of this invention, a friction plate is provided between the damping plate 2 and the fixed plate 13. The friction plate utilizes friction as the primary energy dissipation mechanism. When the structure is subjected to vibration, the friction plate exhibits excellent energy absorption through sliding or micro-motion. This not only significantly reduces the vibration amplitude transmitted to the fixed plate 13 but also converts excess energy into frictional heat, thereby reducing stress concentration in the structure. Unlike traditional energy absorption methods that rely on material elasticity and damping characteristics, the application of the friction plate provides an additional pathway for vibration dissipation. The mechanical energy dissipation characteristics of the friction plate make it particularly suitable for protecting building structures when encountering strong or prolonged vibrations, effectively extending the service life of the structure and reducing fatigue damage to components.

[0042] In practical use, under the influence of risks such as earthquakes, if damping plate 2 breaks due to vibration, in order for the connecting beam damper to still have a connecting or supporting function, such as... Figures 4 to 7As shown, in some embodiments of this utility model, the tension support mechanism 3 includes a connecting rod 31 connected to the embedded plate 11, and a tension component 32 connected between the two connecting rods 31. The connection between the connecting rod 31 and the embedded plate 11 is a ball head 32a, which is rotatably connected to the embedded plate 11. The ball head 32a at the connection between the connecting rod 31 and the two embedded plates 11 allows the structure to flexibly respond to vibration and displacement. The ball head 32a connection allows the connecting rod 31 to rotate freely in multiple axes on the embedded plate 11, enhancing the dynamic response capability of the structure under vibration. It allows for fine-tuning and adjustment without changing the connection reliability, making the structure more adaptable to the vibration environment. The tension component 32 enhances the distance adjustment characteristics of the connecting rod 31, ensuring that the structure can maintain an optimized geometric configuration under vibration conditions, thereby providing a higher level of protection for the safety and durability of the overall building.

[0043] like Figure 6 , Figure 7 As shown, in some embodiments of this utility model, the tensioning assembly 32 includes a rack 32b connected to a connecting rod 31 and a toothed block 32c connected to another connecting rod 31. The toothed block 32c can be pulled out relative to the rack 32b. Limiting blocks 32b1 are evenly arranged on the rack 32b. After the toothed block 32c is pulled out, it locks with the limiting blocks 32b1. The rack 32b and the toothed block 32c allow the connecting rod 31 to be pulled out relative to each other when an external force is applied, while the limiting blocks 32b1 evenly arranged on the rack 32b provide a locking mechanism so that the toothed block 32c can quickly lock with the limiting blocks 32b1 after being pulled out to the correct position. This design not only prevents over-stretching but also avoids the risk of position retraction. The rack 32b provides precise motion guidance, and the rack block 32c and the limit block 32b1 achieve rapid locking, ensuring that any movement changes are within the design specifications and can quickly restore connection stability. Compared with traditional elastic absorption designs, this mechanical control not only ensures the stability of the mechanism, but also improves the controllability of the action and the rapid response capability under stress conditions.

[0044] like Figure 7 As shown, in some embodiments of this utility model, the rack 32b and the toothed block 32c also have a movable cavity 33 at their initial positions. The toothed block 32c is movably disposed within the movable cavity 33. When the damping plate 2 is disconnected, the toothed block 32c is pulled into the rack 32b. When the damping plate 2 is not disconnected, the tension support mechanism 3 does not need to provide support. Only when the damping plate 2 is disconnected does the tension support mechanism 3 function. When not disconnected, the toothed block 32c moves freely within the movable cavity 33. However, when the damping plate 2 is disconnected, the tension support mechanism 3 functions, and the toothed block 32c enters the rack 32b to support the damper, forming a quick and reliable connection.

[0045] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
