Description

Technical Field

[0001] The utility model relates to the technical fields of vibration control and vibration isolation, and is applicable to building structures with vibration control and earthquake resistance requirements. Specifically, it is a novel earthquake-resistant vibration isolation device. Background Art

[0002] With the continuous advancement of the country's urbanization construction, urban rail transit is expanding at an astonishing speed. The new problem it brings is that residential buildings, commercial buildings, TOD buildings, and high-value villas along the urban rail transit are increasingly affected by the vibration of rail transit, and the engineering application of vibration isolation devices is becoming more and more extensive. At the same time, in high-intensity seismic areas, it is required that the vibration isolation device can not only isolate the rail vibration, but also protect the upper building from excessive deformation during an earthquake. Vibration isolation devices are usually based on the design principles of elastic elements (such as springs, rubber pads, air springs, etc.) and damping elements (such as oil dampers, viscoelastic materials), and the combination of these elements is used to achieve vibration isolation or absorption. Its working principle can be simply summarized as: when an external vibration source acts on the system, the elastic element converts part of the vibration energy into elastic potential energy, while the damping element converts the energy into heat energy and dissipates it, thereby effectively reducing the vibration amplitude and energy transmitted to the protected object.

[0003] However, there are generally still some deficiencies and defects in the current vibration isolation devices:

[0004] Insufficient shear resistance: Traditional vibration isolation devices, especially vibration isolation pads that rely on a single material (such as ordinary rubber), often exhibit low shear strength when facing vibrations in complex directions, especially the action of shear forces. This limits their application effects in environments with large loads or complex vibration modes.

[0005] Poor horizontal load-bearing capacity: Many vibration isolation devices are designed with more consideration for vertical vibration isolation, but the control of horizontal vibration transmission is not ideal enough. Under the action of earthquakes, wind loads or other horizontal external forces, this limitation will lead to a reduction in structural stability, unable to effectively transmit and disperse horizontal loads, and increasing the risk of damage. While ensuring the vertical vibration isolation effect, traditional vibration isolation devices often neglect the effective transmission of horizontal dynamic loads. This means that in scenarios where the dynamic performance in both vertical and horizontal directions needs to be considered simultaneously, these devices may not provide sufficient support and stability.

[0006] Therefore, the current vibration isolation devices and earthquake-resistant devices have relatively single functional effects. And often, after the devices have the attributes of vibration isolation and earthquake resistance, they are large in volume and high in cost, and the market is also difficult to accept. In the current highly competitive environment in the field of vibration control, how to develop a vibration isolation device with high vibration isolation rate, high earthquake resistance, small volume and good economy is the hot and difficult point in the current field of vibration control. Summary of the Invention

[0007] In view of the many defects and deficiencies in the above-mentioned background art, the inventor has made improvements and innovations. After design and experiments, a new type of seismic isolation device is finally provided, which has a preloading function, can meet the requirements of engineering vibration isolation, has a seismic protection function, and can simultaneously realize the jacking and vertical load adjustment functions. Therefore, the carrier of the device provided by the present utility model has a wide application range.

[0008] Specifically, the present utility model is implemented as follows: A new type of seismic isolation device is used for installation between the foundation components of a building, between the foundation components and the ground, or between key support point parts. It includes an upper base plate and a lower base plate, and an elastic component disposed between the upper base plate and the lower base plate. It further includes:

[0009] The elastic components are multiple groups, arranged in an array or evenly between the upper base plate and the lower base plate; each group of elastic components is composed of a stack combination of multiple layers of elastic bodies.

[0010] The shear-resistant components are multiple groups, arranged around the elastic components and installed between the upper base plate and the lower base plate. Each group of shear-resistant components has a butt joint structure in which the upper and lower parts are separated and mutually staggered but not completely fitted, so that there is a butt joint gap between the edges of the upper and lower separated parts, which is used to resist the horizontal bearing capacity of earthquake action, can effectively transmit the horizontal load, prevent the shear deformation of the structure in the horizontal direction, and maintain the overall stability of the structure; The buffer members are several, evenly distributed between the contact points between the upper and lower separated parts of the shear-resistant components, providing a flexible isolation layer for the shear-resistant components.

[0011] Further, each group of elastic components includes an upper elastic body, a connecting plate, and a lower elastic body, which are combined in sequence from top to bottom. The upper elastic body and the lower elastic body are both cylindrical, and the connecting plate is disposed between the upper elastic body and the lower elastic body. The upper elastic body and the lower elastic body are made of rubber material, polyurethane material, or metal spring members.

[0012] Further, concave pits or limiting members corresponding to the shape and specifications of each group of elastic components are provided on the plate surfaces of the upper base plate and the lower base plate, which are used to provide horizontal limitation and positioning stability for the elastic components.

[0013] Further, the shear-resistant components include: an upper shear-resistant member, several buffer members, and a lower shear-resistant member. The upper shear-resistant member is fixedly installed on the side edge of the upper base plate, and the lower shear-resistant member is fixedly installed on the side edge of the lower base plate, forming a side baffle-like structure that wraps around the periphery of the elastic components. The upper shear-resistant member and the lower shear-resistant member are both provided with several sections of gaps or a continuous gap in the vertical direction. The buffer members are embedded between the mutually contacting positions of the upper shear-resistant member and the lower shear-resistant member, and flexible isolation is realized in the horizontal direction through the buffer members, and the buffer members do not affect the vertical relative displacement between the upper shear-resistant member and the lower shear-resistant member.

[0014] Further, the lower edge of the upper shear member is processed into a comb-shaped upper comb tooth, and the upper edge of the lower shear member is processed into a comb-shaped lower comb tooth. The upper comb tooth and the lower comb tooth are arranged to be mutually concave-convex and embedded, and there are gaps between the upper shear member and the lower shear member in both the vertical and horizontal directions. A buffer member (602) is provided at each concave-convex contact point on the opposite surfaces of the upper comb tooth and the lower comb tooth to achieve flexible isolation.

[0015] Further, the corner edges of the concave-convex parts of the upper shear member and the lower shear member are rounded structures. The buffer member is arranged at the contact positions of the opposite convex parts of the upper shear member and the lower shear member respectively, for isolating adjacent convex parts, enabling a part of the convex part to be inserted into the corresponding concave part instead of complete embedding, and restricting the lateral offset of the upper shear member and the lower shear member.

[0016] Further, the buffer member is made of an elastic material, and its horizontal cross-section is in an H shape, including two parallel flat plates and a vertical plate placed between the flat plates. The vertical plate divides the clamping cavity into two cavities. One cavity is used to insert the convex part of the upper shear member, and the other cavity is used to insert the convex part of the lower shear member. The vertical plate is placed between the contact points between the upper shear member and the lower shear member.

[0017] Further, the metal spring member includes an inner cylinder inside, and a viscous damping module can be arranged in the inner cylinder. The viscous damping module consists of a movable member, a cavity member and damping liquid. The movable member is fixed to the upper end of the metal spring member, the cavity member is fixed to the lower end of the metal spring member, the damping liquid is arranged inside the cavity member, and the lower end of the movable member is placed inside the cavity member and immersed in the damping liquid. The deformation of the metal spring member drives the movable member to move in the damping liquid to generate a damping force and dissipate energy.

[0018] Further, countersunk holes are arrayedly processed on the lower plane of the lower bottom plate, and through holes are also arrayedly processed on the upper bottom plate at corresponding positions. A plurality of preloading bolts pass through the lower bottom plate from below the countersunk holes and pass through the upper bottom plate from below the first through holes; a preloading nut is installed downward on the preloading bolts from the upper plane of the upper bottom plate; the positions of the preloading bolts avoid the positions where the elastic components are located and are placed between the elastic components.

[0019] Further, it further includes an upper component and a lower component. Among them, the upper component includes an upper panel and several support columns, and the several support columns are placed between the upper panel and the upper bottom plate; the lower component includes a lower embedded plate, and the lower embedded plate is installed below the lower bottom plate; the lower embedded plate is embedded in the lower pier through a lower sleeve and lower anchor bars; the upper embedded plate is embedded in the upper pier through an upper sleeve and upper anchor bars, and the upper end of the upper sleeve is fixedly installed with the upper anchor bars; the upper panel is fixedly connected to the upper embedded plate through bolt connection with the upper sleeve of the upper embedded plate and is fixedly installed on the upper pier.

[0020] The working principle of the present utility model is as follows: The elastic component is stacked by multiple layers of elastomers (such as rubber, polyurethane or metal springs), and the characteristics of different materials and the multi-layer structure are utilized to provide composite elastic properties, which can not only withstand large static loads but also absorb and disperse dynamic loads, especially the impact force during an earthquake. This design can adjust the natural frequency of the system, reduce the vibration transfer efficiency, and achieve effective vibration isolation. The viscous damping module inside the metal spring component of the elastic component generates damping force through the movement of the moving part in the damping liquid, consumes earthquake energy, and accelerates the vibration attenuation, thereby enhancing the durability and safety of the structure. The shear-resistant component adopts a comb-like interlocking structure of the upper shear-resistant part and the lower shear-resistant part, forming a non-fully-fitting butt joint, allowing relative displacement within a certain range, and at the same time using the buffer to provide additional flexible isolation. This design can absorb and disperse the shear force through the friction between the upper shear-resistant part and the lower shear-resistant part and the deformation of the buffer under the action of the horizontal force caused by an earthquake, prevent the shear failure of the structure, and maintain the overall stability of the structure. The buffer is an H-shaped elastic material, which not only provides flexible isolation in the horizontal direction, reducing the direct hard contact between structures, but also allows a certain relative displacement in the vertical direction, which helps to absorb the impact during an earthquake and reduce the dynamic stress of the structure. The new seismic isolation and vibration isolation device provided by the present utility model can be used in multiple combinations, and the model quantity and layout quantity can be flexibly selected according to the load distribution of the building structure; it can provide sufficient stiffness in the vertical direction to support the upper structure; the upper component connected to the upper structure and the lower base plate connected to the foundation or the lower structure achieve vertical flexible isolation through the elastic component inside the isolation device. The elastic component mainly plays the role of adjusting the frequency and isolating vibration, and it isolates vibration through its own vertical reciprocating deformation; at the same time, when isolating horizontal micro-vibrations, the elastic component of the vibration isolation device also has the function of isolating horizontal micro-vibrations. The material of the buffer of the shear-resistant component is an elastomer, which enables flexible isolation between the upper shear-resistant part and the lower shear-resistant part of the shear-resistant component and does not transmit harmful vibrations. The upper shear-resistant part connected to the upper component and the lower shear-resistant part connected to the lower base plate are engaged by comb-like concavities and convexities in the plane direction, which can provide sufficient horizontal bearing capacity, effectively transmit the horizontal load, and prevent the vibration isolation device from becoming unstable under the action of an earthquake. When a large relative vertical displacement occurs between the upper pier and the lower pier, the preload nut and the preload bolt will limit the excessive displacement between the upper component and the lower base plate, thereby limiting the vertical displacement between the upper pier and the lower pier and protecting the upper structure; the elastic component has its own damping, and when the vibration isolation device makes a small vertical reciprocating deformation, the damping effect converts kinetic energy into heat energy, accelerating the vibration attenuation of the system. The present utility model can effectively reduce the dynamic response of the structure during an earthquake, protect the building from earthquake damage, and at the same time can also isolate micro-vibrations in the daily environment, improving the comfort level inside the building and the operation stability of equipment; through the collaborative work of the multi-stage composite structure and multiple functional components, it realizes the effective resistance to earthquake loads and vibration isolation, takes into account the dual requirements of earthquake resistance and vibration isolation, and improves the comprehensive performance of the building.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] (1) Enhanced seismic performance:

[0023] Improved horizontal load-bearing capacity: Through the synergistic effect of the comb-like interlocking structure of the shear-resistant components and the buffer components, the device provides a strong horizontal load-bearing capacity, can effectively resist the shear force caused by earthquakes, effectively transfer the horizontal load, and prevent the vibration isolation device from becoming unstable under earthquake action;

[0024] Energy dissipation and damping effect: The inherent damping characteristics of the built-in elastic components absorb and dissipate a large amount of energy during earthquakes, accelerating the attenuation of vibrations, thereby protecting the building structure from damage; when the vibration isolation device undergoes small vertical reciprocating deformations, the damping effect converts kinetic energy into heat energy, accelerating the attenuation of system vibrations.

[0025] (2) Efficient vibration isolation effect:

[0026] Vertical flexible isolation: The vertical reciprocating deformation ability of the elastic components adjusts the natural frequency of the system, effectively isolates the vertical vibrations transmitted from the ground, improves the comfort of the building and the stability of equipment operation; in addition to resisting earthquake loads, the device can also effectively isolate horizontal micro-vibrations.

[0027] (3) Structural support and stability:

[0028] Reliable vertical support: The device provides sufficient stiffness vertically, ensuring the safe support of the upper structure and maintaining the overall stability of the structure even under earthquake conditions. The combination of pre-tightening bolts and nuts limits the excessive displacement between the upper and lower structures, increases the tensile strength of the building structure, and avoids damage caused by excessive structural displacement.

[0029] (4) Flexibility and adaptability:

Specific embodiments

[0044] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0045] Example 1: As Figures 1 - 7As shown in the figure, a new type of seismic isolation and vibration isolation device is composed of an upper component 1, a lower base plate 2, an upper elastic body 3, a lower elastic body 4, a connecting plate 5, a shear-resistant component 6, a preloading bolt 7, and a preloading nut 8.

[0046] The upper elastic body 3, the connecting plate 5, and the lower elastic body 4 are combined into an elastic component from top to bottom;

[0047] Multiple groups of the elastic components are arranged in an array above the lower base plate 2;

[0048] Multiple groups of elastic components support the upper component 1;

[0049] Four groups of the shear-resistant components 6 are simultaneously arranged on the outside of the support and are arranged between the upper component 1 and the lower base plate 2.

[0050] The upper component 1 is composed of an upper panel 101, support columns 102, and an upper base plate 103. The upper panel 101 and the upper base plate 103 are both square plates. A plurality of the support columns 102 are fixedly arranged above the upper base plate 103, and the upper panel 101 is fixedly arranged above a plurality of the support columns 102.

[0051] The upper elastic body 3 and the lower elastic body 4 are cylinders. The connecting plate 5 is arranged between the upper elastic body 3 and the lower elastic body 4. The upper plane of the connecting plate 5 is processed with a first concave pit, and the lower plane is processed with a second concave pit. The lower end of the upper elastic body 3 is arranged in the first concave pit of the connecting plate 5, and the upper end of the lower elastic body 4 is arranged in the second concave pit of the connecting plate 5. The first concave pit and the second concave pit respectively play a role in positioning and horizontal limitation of the upper elastic body 3 and the lower elastic body 4.

[0052] The upper plane of the lower base plate 2 is processed with third concave pits in an array. The lower ends of a plurality of the lower elastic bodies 4 are arranged in the third concave pits, and the third concave pits play a role in positioning and horizontal limitation of the lower elastic bodies 4.

[0053] The lower plane of the upper base plate 103 is processed with fourth concave pits in an array. The upper ends of a plurality of the upper elastic bodies 3 are arranged in the fourth concave pits, and the fourth concave pits play a role in positioning and horizontal limitation of the upper elastic bodies 3.

[0054] The lower plane of the lower base plate 2 is processed with first countersunk holes in an array. The upper base plate 103 is also processed with first through holes in an array at corresponding positions. A plurality of the preloading bolts 7 pass through the lower base plate 2 from below the first countersunk holes and pass through the upper base plate 103 from below the first through holes;

[0055] The preloading nut 8 is installed on the preloading bolt 7 from above the upper plane of the upper base plate 103.

[0056] As Figures 8 - 9As shown, the shear-resistant component 6 is composed of an upper shear-resistant member 601, a buffer member 602, and a lower shear-resistant member 603. Four groups of the upper shear-resistant members 601 are respectively installed in pairs opposite to each other on the four sides of the upper bottom plate 103 through bolts, and four groups of the lower shear-resistant members 603 are respectively installed in pairs opposite to each other on the four sides of the lower bottom plate 2 through bolts.

[0057] The lower edge of the upper shear-resistant member 601 is processed into a comb shape, called the upper comb teeth, and the upper edge of the lower shear-resistant member 603 is processed into a comb shape, called the lower comb teeth. The upper comb teeth and the lower comb teeth are arranged in an interlocking and concave-convex manner. At the same time, there are gaps between the upper shear-resistant member 601 and the lower shear-resistant member 603 in both the vertical and horizontal directions.

[0058] The buffer member 602 is also arranged between each upper comb tooth and the lower comb tooth. The buffer member 602 isolates the upper shear-resistant member 601 and the lower shear-resistant member 603, enabling the sides of the upper comb teeth and the lower comb teeth in the in-plane direction to achieve flexible isolation and preventing the upper shear-resistant member 601 from being directly connected to the lower shear-resistant member 603 in the in-plane direction.

[0059] The buffer member 602 is made of an elastic material. Its horizontal cross-section is in the shape of an H, and there are square cavities on both sides. One cavity on one side is buckled on the lower comb teeth, and the cavity on the other side is buckled on the upper comb teeth.

[0060] In this embodiment, the vibration isolation device mentioned is pre-pressed before leaving the factory. By applying pressure from the upper plane of the upper panel 101 downwards through a pressure device, the upper elastic body 3 and the lower elastic body 4 are compressed, and the distance between the upper member 1 and the lower bottom plate 2 becomes smaller. After the height of the vibration isolation device is reduced to a preset value, the height of the vibration isolation device is locked by tightening the pre-pressing nut 8, and the pre-pressing process is completed.

[0061] During this process, there is still enough clearance between the lower edge of the upper comb teeth of the upper shear-resistant member 601 and the upper edge of the lower comb teeth of the lower shear-resistant member 603.

[0062] As Figures 10 - 11 shown, the lower embedded plate 12 is embedded in the lower pier 16 through the lower sleeve 13 and the lower anchor bars 14. The lower anchor bars 14 are fixedly installed at the lower end of the lower sleeve 13;

[0063] In this embodiment, the vibration isolation device mentioned is fixedly connected to the lower embedded plate 12 through bolts with the lower sleeve 13 of the lower embedded plate 12, thereby being fixedly installed on the lower pier 16.

[0064] The upper embedded plate 9 is embedded in the upper pier 15 through the upper sleeve 10 and the upper anchor bars 11. The upper anchor bars 11 are fixedly installed at the upper end of the upper sleeve 10;

[0065] In this embodiment, the vibration isolation device mentioned is bolted to the upper sleeve 10 of the upper embedded plate 9, so as to be fixedly connected to the upper embedded plate 9, that is, fixedly installed on the upper pier 15.

[0066] After the construction of the upper structure is completed and the upper static load is stable, adjust the screwing depth of the preloading nut 8 so that there is a certain distance between the preloading nut 8 and the upper plane of the upper panel 101 to meet the vibration isolation requirements of the vibration isolation device.

[0067] As shown in the figure, when it is necessary to adjust the force on the device, the device can be compressed by a jack and then gaskets can be added to the top of the device to adjust the load of the device.

[0068] The load of the upper structure is transmitted to the vibration isolation device through the upper pier 15. After being subjected to the upper load, the elastic component is compressed, and at the same time, as a transmission medium, the load is transmitted to the lower pier 16 through the lower bottom plate 2. The shear resistance component 6 does not transmit the vertical load. The vibration isolation device enables the upper pier 15 and the lower pier 16 to be flexibly connected through the elastic component, playing a role in isolating vibration.

[0069] When the building structure is subjected to earthquake action, the upper shear member 601 connected to the upper member 1 and the lower shear member 603 connected to the lower bottom plate 2 are engaged in a comb-like concave-convex manner in the in-plane direction, generating a horizontal bearing capacity sufficient to resist the earthquake action, effectively transmitting the horizontal load, and preventing the vibration isolation device from becoming unstable under earthquake action.

[0070] At the same time, when the vertical component of the earthquake action is relatively large and there is a large relative vertical displacement between the upper pier 15 and the lower pier 16, the preloading nut 8 and the preloading bolt 7 will limit the excessive displacement between the upper member 1 and the lower bottom plate 2, thereby limiting the vertical displacement between the upper pier 15 and the lower pier 16 and protecting the upper structure.

[0071] Finally, it should be noted that the above has clearly and completely described the concept, specific structure and technical effects generated by the present invention in combination with the embodiments and the drawings to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present invention. In addition, all the connection and coupling relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the more optimal coupling structure that can be formed according to the specific implementation situation by adding or reducing coupling accessories. Each technical feature in the present invention can be combined interactively without conflicting with each other.
