Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a self-resetting multi-stage shock-absorbing energy-absorbing disc spring soft steel damper. Background Art

[0002] In building and bridge engineering, dampers are widely used to reduce the response of structures under dynamic effects such as earthquakes or wind loads. Although traditional dampers, such as metal dampers or rubber dampers, can absorb a certain amount of energy, they usually only provide a single-stage energy dissipation capacity and are often difficult to recover to their original state after experiencing a large displacement, which limits their effectiveness in continuous vibration events.

[0003] In addition, traditional dampers often have difficulty distributing loads evenly when faced with complex dynamic loads, especially multi-directional shear forces, which may cause excessive stress on one side of the structure while the other side is not adequately protected, affecting its overall shock absorption performance and stability. This is particularly unfavorable in earthquake-prone areas or in structures with extremely high safety requirements.

[0004] Therefore, the development of modern earthquake-resistant technology requires a new type of damper that can provide energy dissipation in multiple stages to more effectively reduce the response of the structure. At the same time, this damper needs to be able to automatically reset after the earthquake to prepare for possible subsequent vibrations. In addition, this damper should also have good multi-directional energy dissipation capabilities and be able to maintain a stable shock absorption effect under loads in different directions. These requirements have led to the development of multi-stage shock absorption and energy dissipation technology in order to improve the safety and reliability of structures when facing complex dynamic loads.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0034] Preferably, the first deformation hole and the second deformation hole are both arranged in a strip shape.

[0035] Preferably, one side of the pull cylinder is in contact with the surface of the second shear damper, and the surface of the pull plate is in contact with the surface of the first shear damper.

[0036] Preferably, the bending angle of the adapter plate ranges from 15 to 180 degrees.

[0037] Beneficial effects:

[0038] When the present solution is in use, the mounting parts are fixed to the surveying and mapping points of the building substrate. When the two substrates are shaking, the two mounting parts on the side are synchronously displaced accordingly. When the two mounting parts are displaced up and down in an alternating manner, the distance between the two mounting parts changes, and a certain degree of deformation occurs through the adapter plate. At the same time, the two arched soft steels are also deformed. When the arched soft steel is subjected to tension, the arc angle gradually approaches the inclined shape under its pulling, and has the force to pull the first shear damper and the second shear damper closer to each other. When the arched soft steel is subjected to extrusion pressure, the arc of the arched soft steel increases, and the distance between the first shear damper and the second shear damper begins to move away. In this process, a first-level damping energy dissipation is formed by the adapter plate and the arched soft steel, which can not only adapt to the load of the deformation of the building substrate on the installation structure and ensure a stable connection state, but also has a better energy dissipation effect.

[0039] When the first shear damper and the second shear damper are close to each other, they press the pull plate and the pull cylinder respectively, so that when the pull plate moves toward the pull cylinder, the disc spring therebetween is compressed. While the disc spring is compressed, the pull plate and the pull cylinder move toward each other, and the pull column fixed on the surface of the pull plate slides on the inner wall of the tube, and at the same time, the pull cylinder slides on the surface of several extended screws with the connecting ring on the surface. If the first shear damper and the second shear damper are far away from each other, the second shear damper pulls the pull column through the limit block, and the pull column compresses one end of the disc spring through the pull plate, and the first shear damper pulls the connecting ring through several extended screws on the surface, so that the connecting ring compresses the other end of the disc spring with the pull cylinder, so that the disc spring contracts. In summary, this scheme can adapt to the displacement change of the mounting part acted on by the base, and the extrusion or pulling force of the bow-shaped soft steel can form a contraction force of the disc spring, thereby realizing further damping and buffering. At the same time, the disc spring has an elastic reset force on the bow-shaped soft steel, which can be reset after the base is reset, thereby ensuring the stability of repeated use.

[0040] In summary, the extrusion force and the tension force on the movement of the first shear damper and the second shear damper toward or away from each other will produce a compression effect on the same disc spring, ensuring the stability of the secondary damping effect and maintaining the maximum utility development of the disc spring elasticity;

[0041] The present invention can ensure that a stable plane is provided as a carrier for the reset damping seat when subjected to force through the cooperation of the first shear damper and the second shear damper. The structural principles of the first shear damper and the second shear damper are basically the same. Taking the first shear damper as an example, when subjected to staggered shear force, the shear force acts on the first outer cover and the first oblique plastic layer plate through the two first mounting ears respectively. The shear forces interacting in two directions cause the first outer cover and the first oblique plastic layer plate to begin to stagger. The first outer cover and the first core plate are tightly fitted and fixed on the inner wall and surface of the first viscoelastic layer plate. The first oblique plastic layer plate is fixed on the first viscoelastic layer plate. The inner wall of the elastic layer is tightly fitted and fixed, and the staggered shear force will cause an extrusion force in different directions to be formed in the first viscoelastic layer, causing the first outer cover and the first core plate to tilt, while the first oblique plastic layer will tilt in another direction. The multi-layer tilting effect will form a tensile force and an extrusion force in the first viscoelastic layer, so that the force can be buffered and energy consumed under the deformation of the multi-layer, and the horizontal shear force can be well damped and protected. At the same time, the problem of uneven force on the two arched soft steels on the same side caused by the horizontal shear force is reduced, which has a protective effect on the arched soft steel and prevents one side from being subjected to excessive force and unable to reset.

[0042] In summary, it can be understood that the bow-shaped soft steel has a better damping effect on the up and down staggered forces of the two substrates, and can be well coordinated with the reset damping seat to form a multi-level damping design. However, the horizontal misalignment force will cause excessive pressure on one side of the two bow-shaped soft steels on the same side, and it is impossible to achieve good supporting force. Therefore, the shear effect of the horizontal misalignment force is protected by the first shear damper and the second shear damper to avoid damage and inability to reset.

DETAILED DESCRIPTION

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0058] like Figures 1 to 11 As shown, a self-resetting multi-stage shock-absorbing energy-absorbing disc spring 11 soft steel damper comprises:

[0059] One side of the mounting member 6 is fixedly connected to the base 7, and the mounting member 6 is used for fitting and mounting on the surface of the base 7;

[0060] The first shear damper 2 and the second shear damper 3 are arranged in parallel, and both ends of the first shear horizontal damper and the second shear damper 3 are fixedly connected with arched soft steel 4;

[0061] The two corresponding arched mild steels 4 on the same side of the first shear damper 2 and the second shear damper 3 are arranged in an arched shape.

[0062] The adapter plate 5 is located on the inner wall of the mounting member 6 and is fixedly connected. The adapter plate 5 is located on the opposite surfaces of the two same-side arched mild steels 4 and is fixedly connected.

[0063] The reset damping seat 1 is arranged between the first shear damper 2 and the second shear damper 3. The reset damping seat 1 is deformed as the distance between the first shear damper 2 and the second shear damper 3 changes, and controls its reset.

[0064] The present invention can absorb more dynamic energy at different stages through a unique multi-stage energy dissipation design, significantly improving the overall shock absorption effect. At the same time, the automatic reset function of the device avoids the trouble of manual reset of traditional dampers after an earthquake, greatly improving the convenience and efficiency of use. In addition, this damper can effectively cope with multi-directional shear forces and enhance the stability and safety of the structure under various loads. This not only extends the service life of the building structure and reduces the maintenance cost after an earthquake, but also protects personal and property safety. Overall, the device provides an efficient and reliable shock absorption solution for the field of seismic design, demonstrating excellent performance in improving the seismic resistance of building structures, reducing the difficulty of post-earthquake maintenance, and enhancing structural durability;

[0065] The significant progress of the self-resetting multi-stage shock-absorbing energy-absorbing disc spring 11 soft steel damper of the present invention in structural shock absorption technology is reflected in its unique bidirectional force mechanism. Whether it is subjected to extrusion force or tensile force, the disc spring 11 in the device can be compressed accordingly. This innovative design enables the damper to work effectively under multi-directional loads, thereby achieving more comprehensive and balanced energy absorption and dissipation. This bidirectional compression effect not only improves the shock absorption efficiency, but also realizes the automatic reset function of the damper through the elastic restoring force of the disc spring 11, greatly enhancing the continuous use performance after multiple vibrations. In addition, this outstanding technological advancement also means that the damper can better protect the safety of the structure in practical applications, reduce the need for maintenance and repair, and bring important innovations to the field of earthquake resistance.

[0066] Specifically, Figure 8 and Figure 5 As shown: the reset damping seat 1 includes a disc spring 11 located between the first shear damper 2 and the second shear damper 3, a pull cylinder 16 is provided on the surface of the disc spring 11, the inner wall of the pull cylinder 16 is fitted with one end of the disc spring 11, and a pull plate 12 is fitted with the other end of the disc spring 11, and a pull column 13 is fixedly connected to one side of the pull plate 12, and the pull column 13 penetrates and slides on the inner wall of the disc spring 11;

[0067] The surface of the pull column 13 penetrates and slides on the surface of the second shear damper 3, and one end of the pull column 13 is fixedly connected to a limit block 14 that cooperates with the pulling of the second shear damper 3;

[0068] One end of the pull tube 16 is fixedly connected to a connecting ring 15 , and a plurality of extension screws 17 are slidably penetrated on the surface of the connecting ring 15 , and the surface of the extension screws 17 is penetrated and fixed on the surface of the first shear damper 2 .

[0069] By setting a disc spring 11, the disc spring 11 is a flat conical spring, which is usually made of spring steel and is characterized by a hole in the center part and the surrounding edges flaring outward. The disc spring 11 is designed to withstand a large amount of axial load through elastic deformation while occupying only a small space in the axial direction. The design of the disc spring 11 allows them to be used alone, or stacked together in a series or parallel combination, so as to adjust the stiffness and load characteristics of the overall spring combination. When subjected to axial load, the disc spring 11 will deform along the conical profile and generate a corresponding elastic force. This deformation can absorb energy and release energy after unloading, so that the disc spring 11 returns to its original state. This characteristic makes the disc spring 11 have better performance in use in places where large loads and limited space are required. In the damper system, the disc spring 11 can be used to provide the necessary elastic force to help the system return to its initial position after experiencing vibration or impact. At the same time, this elastic behavior of the disc spring 11 also enables them to be used as energy dissipation elements in the damper to help the system absorb and dissipate the kinetic energy transmitted through the structure.

[0070] Specifically, Figure 3 and Figure 7 As shown: the adapter plate 5 is arranged in an arc shape and / or a straight shape, and is used to calibrate the connection angle between the mounting member 6 and the bow-shaped mild steel 4.

[0071] The adapter plate 5 is a key component that plays a role in connecting and adjusting the angle in the device. In this invention, the adapter plate 5 can be arranged in an arc shape and / or a straight shape. The advantage of this design is that it can be more flexibly adapted to various needs and meet different connection angle requirements.

[0072] The arc-shaped adapter plate 5 can provide a wider range of angle selection, so that the connection angle between the mounting member 6 and the arched mild steel 4 can be adjusted within a wider range. This design is particularly important in situations where the connection angle needs to be adjusted to adapt to different working conditions or optimize the damping effect.

[0073] On the other hand, the straight adapter plate 5 can provide a more stable connection, especially in the occasions where a large amount of axial load or a high-strength connection is required, the straight adapter plate 5 can provide better support and stability.

[0074] Specifically, Fig. 9As shown: the first shear damper 2 comprises a first outer cover 21, a first core plate 22 is fixedly disposed on the inner wall of the first outer cover 21, and a first viscoelastic layer plate 24 is fixedly attached to the inner wall of the first outer cover 21;

[0075] A first core hole 25 is formed on one side of the first viscoelastic layer plate 24 to be fixed with the first core plate 22;

[0076] The first oblique plastic layer plate 23 is fixedly connected to the inner wall of the first viscoelastic layer plate 24, and a first fixing hole 26 for fixing the first oblique plastic layer plate 23 is formed through the surface of the first viscoelastic layer plate 24;

[0077] A plurality of first deformation holes 27 are provided through the surfaces of the first oblique plastic layer plate 23 and the first viscoelastic layer plate 24. The first deformation holes 27 are used to cooperate with the displacement and sliding of the corresponding extension screw rods 17.

[0078] The surfaces of the first outer cover 21 and the first core plate 22 are penetrated by a plurality of through holes 28 for axially fixing the extended screw rod 17;

[0079] First mounting ears 29 are fixed on the surfaces of the first outer cover 21 and the first inclined plastic layer plate 23 . The first mounting ears 29 are fixedly connected to the corresponding two arched mild steels 4 .

[0080] Specifically, Fig.10 As shown: the second shear damper 3 comprises a second outer cover 31, a second core plate 32 is fixedly provided on the inner wall of the second outer cover 31, and a second viscoelastic layer plate 34 is fixedly attached to the inner wall of the second outer cover 31;

[0081] A second core hole 35 is formed on one side of the second viscoelastic layer plate 34 to cooperate with the second core plate 32 for fixing;

[0082] The second oblique plastic layer plate 33 is fixedly connected to the inner wall of the second viscoelastic layer plate 34, and a second fixing hole 36 for fixing the second oblique plastic layer plate 33 is formed through the surface of the second viscoelastic layer plate 34;

[0083] A through-tube 38 is fixedly passed through the surfaces of the second outer cover 31 and the second core plate 32, and the through-tube 38 is used to cooperate with the axial limiting sliding of the pull column 13;

[0084] A plurality of second deformation holes 37 are provided through the surfaces of the second oblique plastic layer plate 33 and the second viscoelastic layer plate 34. The second deformation holes 37 are used to cooperate with the displacement and sliding of the through tube 38.

[0085] Second mounting ears 39 are fixed on the surfaces of the second outer cover 31 and the second oblique plastic layer plate 33 . The second mounting ears 39 are fixedly connected to the corresponding two arched mild steels 4 .

[0086] The first shear damper 2 and the second shear damper 3 are used to provide effective structural shock absorption. They are usually installed in parallel at key locations of buildings or bridges to absorb shear motion energy caused by external forces (such as earthquakes or wind loads).

[0087] When a structure undergoes shear motion, the shear damper converts kinetic energy into heat or other forms through internal mechanisms (such as friction, viscosity or metal buckling), thereby reducing the energy transferred to the main structure. In the event of an earthquake or other vibration, the response of the structure can be reduced, thereby reducing structural damage, ensuring the integrity of the building and the safety of personnel. By reducing the vibration amplitude of the structure, the shear damper helps to extend the service life of the building or bridge and reduce maintenance costs. In this invention, the setting of the shear damper allows automatic reset after vibration, providing a guarantee for continuous use and long-term stability.

[0088] Specifically, Figure 8 As shown in the figure, the diameter of the pull plate 12 is smaller than the inner diameters of the connecting ring 15 and the pull tube 16 , and the pull column 13 axially penetrates and slides on the inner wall of the pull tube 16 .

[0089] In this design, the diameter of the pull plate 12 is designed to be smaller than the inner diameter of the connecting ring 15 and the pull tube 16. This design allows the pull plate 12 to move freely inside the connecting ring 15 and the pull tube 16 without being hindered too much. This design allows the pull plate 12 to slide smoothly inside the pull tube 16 when the disc spring 11 is subjected to a compressive or stretching force, while preventing the disc spring 11 from being over-compressed.

[0090] Specifically, Fig. 9 and Fig.10 As shown, the first deformation hole 27 and the second deformation hole 37 are both arranged in a strip shape.

[0091] The first deformation hole 27 can adapt to the extension screw 17 being fixed inside without being affected by the internal deformation force, and the second deformation hole 37 can also prevent the tube 38 from being affected.

[0092] Specifically, Figure 4 As shown, one side of the pull tube 16 is in contact with the surface of the second shear damper 3 , and the surface of the pull plate 12 is in contact with the surface of the first shear damper 2 .

[0093] The pull tube 16 and the pull plate 12 can be directly attached to the surfaces of the first shear damper 2 and the second shear damper 3 and can withstand pressure during the attachment.

[0094] The overall installation state of the adapter plate 5 at 45 degrees and 180 degrees: the bending angle of the adapter plate 5 includes 15-180 degrees.

[0095] When the present solution is in use, it is fixed to the surveying point of the building base 7 by the mounting member 6. When the two bases 7 are shaking, the two mounting members 6 are displaced synchronously. When the two mounting members 6 are displaced up and down alternately, the distance between the two mounting members 6 changes, and a certain degree of deformation occurs through the adapter plate 5. At the same time, the two arched soft steels 4 are also deformed. When the arched soft steel 4 is subjected to tension, the arc angle gradually approaches the inclined shape under its pulling, and has the force to pull the first shear damper 2 and the second shear damper 3 closer to each other. When the arched soft steel 4 is subjected to extrusion pressure, the curvature of the arched soft steel 4 increases, and the distance between the first shear damper 2 and the second shear damper 3 begins to move away. In this process, a first-level damping energy dissipation is formed through the adapter plate 5 and the arched soft steel 4. When the first shear damper 2 and the second shear damper 3 are close to each other, they press the pull plate 12 and the pull cylinder 16 respectively, so that the pull plate 12 moves toward the pull cylinder 16, and the disc spring 11 therebetween is compressed. While the disc spring 11 is compressed, the pull plate 12 and the pull cylinder 16 move toward each other, and the pull column 13 fixed on the surface of the pull plate 12 slides on the inner wall of the through cylinder 38, and the pull cylinder 16 slides on the surface of several extension screws 17 with the connecting ring 15 on the surface. If the first shear damper 2 and the second shear damper 3 are far away from each other, the second shear damper 3 passes through the limit The block 14 pulls the pull column 13, and the pull column 13 compresses one end of the disc spring 11 through the pull plate 12. The first shear damper 2 pulls the connecting ring 15 through a plurality of extended screws 17 on the surface, so that the connecting ring 15 compresses the other end of the disc spring 11 with the pull tube 16, so that the disc spring 11 contracts; In summary, the extrusion force and the pulling force on the first shear damper 2 and the second shear damper 3 towards or away from each other will produce a compression effect on the same disc spring 11, ensuring the stability of the secondary damping effect and maintaining the maximum utility development of the elasticity of the disc spring 11;

[0096] The present invention can ensure that a stable plane is provided as a carrier for the reset damping seat 1 when subjected to force through the cooperation of the first shear damper 2 and the second shear damper 3. The structural principles of the first shear damper 2 and the second shear damper 3 are basically the same. Taking the first shear damper 2 as an example, when subjected to staggered shear force, the shear force acts on the first outer cover 21 and the first oblique plastic layer plate 23 respectively through the two first mounting ears 29. The shear forces interacting in two directions cause the first outer cover 21 and the first oblique plastic layer plate 23 to begin to stagger, and the first outer cover 21 and The first core plate 22 is tightly fitted and fixed on the inner wall and surface of the first viscoelastic layer plate 24, and the first oblique plastic layer plate 23 is tightly fitted and fixed on the inner wall of the first viscoelastic layer plate 24. The staggered shear force will cause an extrusion force in different directions to be formed in the first viscoelastic layer plate 24, causing the first outer cover 21 and the first core plate 22 to tilt, while the first oblique plastic layer plate 23 will tilt in another direction. The inclination of the multiple layers will form a tensile force and an extrusion force in the first viscoelastic layer plate 24, so that the force can be buffered and energy consumed under the deformation of the multiple layers. In summary, it can be understood that the arched soft steel 4 has a good damping effect on the upper and lower interlaced forces of the two bases 7, and can be well coordinated with the reset damping seat 1 to form a multi-stage damping design. However, the horizontal misalignment force will cause excessive pressure on one side for the two arched soft steels 4 on the same side, and it is impossible to achieve good supporting force. Therefore, the first shear damper 2 and the second shear damper 3 are used to protect against the shear effect of the horizontal misalignment force to avoid damage and inability to reset.

[0097] The self-resetting multi-stage shock-absorbing energy-absorbing disc spring 11 soft steel damper involved in the present invention overcomes the limitations of uneven distribution and difficulty in self-resetting of traditional dampers under the action of multi-directional shear forces, and provides a shock-absorbing device with multi-stage energy dissipation and automatic reset functions. The device achieves synchronous displacement and effective energy absorption when the building base 7 shakes through the unique bow-shaped soft steel 4 and disc spring 11 structure, and has the ability to automatically return to its original position after being stressed. Its structural design ensures stability and uniform force distribution under complex loads, significantly improving the safety and shock-absorbing effect of buildings or structures under dynamic effects such as earthquakes.
