Description

Technical Field

[0001] This invention relates to the field of bearing structure technology, specifically to an optimized device for seismic-resistant and efficient seismic isolation bearing structures. Background Technology

[0002] The mainstream seismic isolation bearing is a laminated rubber composite structure. The core is a vulcanized composite of multiple layers of high-damping rubber and thin steel plates, with a lead core in the center and connecting steel plates on the top and bottom. The steel plates provide vertical stiffness and load-bearing capacity, while the rubber provides horizontal flexibility and restoring force. The lead core efficiently dissipates seismic energy through plastic deformation. The whole structure integrates vertical load-bearing, horizontal seismic isolation, damping energy dissipation, and self-restoring.

[0003] During the on-site installation and deployment of high-efficiency seismic isolation bearings, due to the significant differences in structural forms, load distributions and stress conditions of different buildings, traditional seismic isolation bearings are usually difficult to flexibly adjust their working state according to the site conditions, differences in the load of the superstructure and seismic fortification requirements. This results in insufficient adaptability of their actual performance to the on-site working conditions, which is not conducive to fully realizing the vibration reduction effect of the seismic isolation bearings.

[0004] Therefore, we propose an optimized structure for seismic-resistant and efficient seismic isolation bearings. Summary of the Invention

[0005] The purpose of this invention is to provide a seismic-resistant and efficient seismic isolation bearing structure optimization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seismic-resistant and efficient seismic isolation bearing structure optimization device, comprising a lower support plate and an upper support plate, wherein a rubber block is fixedly connected between the lower support plate and the upper support plate, and a plurality of steel plates are embedded parallel to the inner side of the rubber block, wherein a splicing structure is provided on the surface of the rubber block, the splicing structure comprising a plurality of through holes opened on the surface of the steel plates and the rubber block, the plurality of through holes being arranged in a row, and a plurality of rubber strips being detachably installed on the surface of the rubber strip;

[0007] The outer side of several rubber strips is provided with a fixing structure for tightly installing several rubber strips. The fixing structure includes two L-shaped fixing strips. Sliders are slidably installed on both sides of the fixing strips. A U-shaped cross frame is fixedly connected to the surface of the slider. The two cross frames and the L-shaped fixing strips form a rectangular ring structure.

[0008] The aforementioned components achieve the following effects: By setting up a splicing structure, rubber strips can be flexibly added to the main body of the rubber block according to the seismic fortification level of the building and the site conditions. This facilitates adaptation to the differentiated usage requirements of high-efficiency seismic isolation bearings for different building sites, thereby optimizing the overall stress and seismic isolation energy dissipation effect of the bearing. To a certain extent, this improves the adaptability and actual performance of the seismic-resistant high-efficiency seismic isolation bearing. By setting up a fixing structure, the rubber strips installed on the outer periphery of the rubber block can be surrounded and fixed, making the rubber strips fit more tightly and the positioning more reliable. This effectively avoids problems such as loosening, displacement, or even falling off of the rubber strips under long-term stress or external disturbances, further significantly improving the overall structural stability and safety of use after the addition of the rubber strips, and ensuring that the components can continue to play a stable role in subsequent work.

[0009] Preferably, the splicing structure further includes several steel blocks embedded inside the rubber strip, and steel rods are fixedly connected to the surface of the steel blocks, the size of the steel rods being compatible with the size of the through holes.

[0010] The effect achieved by the above components is that the steel rod can be inserted into the inside of the through hole, which enables the rapid splicing of rubber strips and rubber blocks.

[0011] Preferably, a row of mounting holes is provided on the side of the rubber strip away from the steel rod, and the size of the mounting holes is adapted to the size of the steel rod.

[0012] The effect achieved by the above components is that when the seismic resistance requirement is relatively high, additional rubber strips can be added to the back of the rubber strip to reinforce the seismic resistance of the support structure.

[0013] Preferably, the fixing structure further includes a positioning block fixedly connected to the surface of the slider, a pin is slidably inserted inside the positioning block, a connecting block is fixedly connected to the end of the pin, a locking block is fixedly connected to the surface of the connecting block, and a plurality of locking grooves are formed on the surface of the fixing strip.

[0014] The effect achieved by the above components is that the locking block is locked inside the slot, which can realize the fixing work between the slider and the fixing bar after the movement.

[0015] Preferably, the card block is a right triangular prism structure, the cross-section of the card block is a right triangle, and the two right-angled sides of the card block are parallel to the slider and the connecting block, respectively.

[0016] The effect achieved by the above components is that the straight triangular prism structure of the locking block has an irreversible effect during the relative movement between it and the locking slot.

[0017] Preferably, a spring is fitted onto the surface of the pin, and the two ends of the spring are fixedly connected to the connecting block and the positioning block, respectively.

[0018] The effect achieved by the above components is as follows: after the rubber strip is initially installed, the L-shaped fixing strip is attached to one of the corners of the support structure. When the horizontal frame moves to the position attached to the surface of the rubber strip, the locking block is inserted into the corresponding slot, thereby achieving a tight fixation of the rubber strip.

[0019] Preferably, the surface of the fixing strip is provided with an auxiliary structure, the auxiliary structure including a plurality of first moving blocks slidably connected to the side walls of the two fixing strips, a first elastic frame fixedly connected to the surface of the first moving blocks on the two fixing strips, two sliding grooves are opened on the inner side of the horizontal frame, the two sliding grooves are slidably connected to a second moving block, and a second elastic frame is fixedly connected to the surface of the second moving block on the inner side of the two horizontal frames.

[0020] The aforementioned components achieve the following effects: By setting up auxiliary structures, during assembly, the first and second elastic frames with U-shaped structures can support and position the rubber strip at a certain distance, allowing the upper and lower sides of the rubber strip to fit evenly and smoothly onto the surface of the rubber block. This significantly improves the installation accuracy and fixing stability of the rubber strip on the rubber block. At the same time, the first and second elastic frames with U-shaped structures themselves have good elastic deformation and buffering energy absorption characteristics. Under seismic action or external load impact, they can effectively absorb and dissipate some energy, reduce the stress and vibration impact on the structure, and further enhance the buffering performance and seismic damping effect of the overall seismic isolation bearing structure.

[0021] Preferably, both the first moving block and the second moving block are U-shaped structures.

[0022] The effect achieved by the above components is that the first and second moving blocks of the U-shaped structure have a certain degree of elasticity.

[0023] Preferably, the slider has an internal threaded bolt inserted into it, which serves to fix the horizontal frame after it has been moved.

[0024] The effect achieved by the above components is that the bolts prevent the cross frame from slipping off the inside of the slider.

[0025] Preferably, a row of circular grooves is formed on the surface of the cross frame, and the size of the bolt is adapted to the size of the circular grooves.

[0026] The effect achieved by the above components is that the bolts inserted into the inner side of the circular groove further improve the stability of fixing the cross frame.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. By setting up a splicing structure, this invention allows for the flexible addition of rubber strips to the main body of the rubber block according to the seismic fortification level of the building and the site conditions. This facilitates the adaptation to the differentiated usage requirements of high-efficiency seismic isolation bearings for different building sites, thereby optimizing the overall stress and seismic isolation energy dissipation effect of the bearing and improving the adaptability and actual performance of the seismic-resistant high-efficiency seismic isolation bearing to a certain extent.

[0029] 2. By setting a fixed structure, the present invention can complete the surrounding and fixing of the rubber strip installed on the outer periphery of the rubber block, so that the rubber strip and the rubber block fit more tightly and the positioning is more reliable. It effectively avoids problems such as loosening, displacement or even falling off of the rubber strip under long-term stress or external disturbance, and further significantly improves the overall structural stability and safety of use after the rubber strip is added, ensuring that the component can continue to play a stable role in subsequent work.

[0030] 3. By setting up an auxiliary structure, the present invention allows the U-shaped first and second elastic frames to support and position the rubber strip at a certain distance during assembly. This ensures that the upper and lower sides of the rubber strip can be evenly and smoothly attached to the surface of the rubber block, thereby significantly improving the installation accuracy and fixing stability of the rubber strip on the rubber block. At the same time, the U-shaped first and second elastic frames themselves have good elastic deformation and buffering energy absorption characteristics. Under seismic action or external load impact, they can effectively absorb and dissipate some energy, reduce the stress and vibration impact on the structure, and further enhance the buffering performance and seismic damping effect of the overall seismic isolation bearing structure.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 8This invention provides a technical solution: an optimized structure device for seismic isolation bearings, comprising a lower support plate 1 and an upper support plate 2, with a rubber block 3 fixedly connected between the lower support plate 1 and the upper support plate 2. A plurality of steel plates 4 are embedded parallel to each other on the inner side of the rubber block 3. A splicing structure 5 is provided on the surface of the rubber block 3, including a plurality of through holes 55 formed on the surfaces of the steel plates 4 and the rubber block 3, arranged in a row. A plurality of rubber strips 51 are detachably mounted on the surface of the rubber strips 51. A fixing structure 6 is provided on the outer side of the plurality of rubber strips 51 for tightly installing the plurality of rubber strips 51. The fixing structure 6 includes two L-shaped fixing strips 61, with sliders 69 slidably mounted on both sides of each fixing strip 61. A U-shaped horizontal frame 62 is fixedly connected to the surface of the sliders 69, and the two horizontal frames 62 and the L-shaped fixing strips 61 form a rectangular ring structure. By setting the splicing structure 5, rubber strips 51 can be flexibly added to the main body of the rubber block 3 according to the seismic fortification level of the building and the site conditions. This facilitates the adaptation to the differentiated usage requirements of high-efficiency seismic isolation bearings for different building sites, thereby optimizing the overall stress and seismic isolation energy dissipation effect of the bearing. To a certain extent, this improves the adaptability and actual performance of the seismic-resistant high-efficiency seismic isolation bearing. By setting the fixing structure 6, the rubber strips 51 installed on the outer periphery of the rubber block 3 can be surrounded and fixed, making the rubber strips 51 and the rubber block 3 fit more tightly and the positioning more reliable. This effectively avoids problems such as loosening, displacement or even falling off of the rubber strips 51 under long-term stress or external disturbances, and further significantly improves the overall structural stability and safety of use after the addition of the rubber strips 51. This ensures that the components can continue to play a stable role in subsequent work. The surface of the fixing strip 61 is provided with an auxiliary structure 7.

[0042] The specific setup and function of its splicing structure 5, fixing structure 6, and auxiliary structure 7 will be explained below.

[0043] like Figures 1-4 As shown, the splicing structure 5 also includes several steel blocks 53 embedded inside the rubber strip 51. Steel rods 54 are fixedly connected to the surface of each steel block 53, and the dimensions of the steel rods 54 are compatible with the dimensions of the through holes 55. The steel rods 54 are inserted into the inside of the through holes 55, enabling rapid splicing between the rubber strip 51 and the rubber blocks 3. A row of mounting holes 52 is provided on the side of the rubber strip 51 away from the steel rods 54, and the dimensions of the mounting holes 52 are compatible with the dimensions of the steel rods 54. When the seismic resistance requirement is high, additional rubber strips 51 can be added to the back side of the rubber strip 51 to reinforce the seismic resistance of the support structure.

[0044] like Figure 1 and Figure 5 as well as Figure 6As shown, the fixing structure 6 also includes a positioning block 64 fixedly connected to the surface of the slider 69. A pin 65 is slidably inserted inside the positioning block 64, and a connecting block 66 is fixedly connected to the end of the pin 65. A locking block 68 is fixedly connected to the surface of the connecting block 66, and several slots 63 are formed on the surface of the fixing strip 61. The locking block 68 is locked inside the slots 63, enabling the fixing of the slider 69 and the fixing strip 61 after movement. The locking block 68 is a right triangular prism structure with a right-angled triangle cross-section, and its two right-angled sides are parallel to the slider 69 and the connecting block 66, respectively. The right triangular prism structure of the locking block 68 has an irreversible effect during relative movement with the slots 63. A spring 67 is fitted onto the surface of the pin 65, and both ends of the spring 67 are fixedly connected to the connecting block 66 and the positioning block 64, respectively. After the rubber strip 51 is initially installed, the L-shaped fixing strip 61 is attached to one of the corners of the support structure. When the horizontal frame 62 moves to the position attached to the surface of the rubber strip 51, the locking block 68 is inserted into the inner side of the corresponding slot 63, thereby achieving the tight fixing of the rubber strip 51.

[0045] like Figure 1 and Figures 5-8 As shown, the auxiliary structure 7 includes several first movable blocks 76 that are slidably connected to the side walls of two fixed bars 61. A first elastic frame 71 is fixedly connected to the surface of the first movable blocks 76 on the two fixed bars 61. Two sliding grooves 75 are opened on the inner side of the horizontal frame 62. The two sliding grooves 75 are slidably connected to a second movable block 77. A second elastic frame 72 is fixedly connected to the surface of the second movable block 77 on the inner side of the two horizontal frames 62. By setting the auxiliary structure 7, during the assembly process, the U-shaped first elastic frame 71 and second elastic frame 72 can support and position the rubber strip 51 at a certain distance, so that the upper and lower sides of the rubber strip 51 can be evenly and flatly attached to the surface of the rubber block 3. This significantly improves the installation accuracy and fixing stability of the rubber strip 51 on the rubber block 3. At the same time, the U-shaped first elastic frame 71 and second elastic frame 72 themselves have good elastic deformation and buffer energy absorption characteristics. Under seismic action or external load impact, they can effectively absorb and dissipate some energy, reduce the stress and vibration impact on the structure, and further enhance the buffer performance and seismic damping effect of the overall seismic isolation bearing structure. The first moving block 76 and the second moving block 77 are both U-shaped structures. The U-shaped first moving block 76 and the second moving block 77 have certain elastic properties. The internal thread of the slider 69 is fitted with a bolt 73, which is used to fix the horizontal frame 62 after movement. The setting of the bolt 73 prevents the horizontal frame 62 from slipping off the inside of the slider 69. A row of circular grooves 74 are formed on the surface of the cross frame 62, and the size of the bolt 73 is adapted to the size of the circular grooves 74. The bolt 73 is inserted into the inside of the circular grooves 74, which further improves the stability of fixing the cross frame 62.

[0046] Working principle: The lower support plate 1 is fixedly connected to the building's foundation, and the upper support plate 2 is fixedly connected to the building's superstructure. Rubber blocks 3 and several internally embedded steel plates 4 are alternately stacked, forming the core load-bearing and seismic isolation structure of the support. The embedded multi-layered steel plates 4 provide sufficient vertical stiffness and load-bearing capacity, stably bearing the constant and live loads of the superstructure, effectively limiting excessive compression deformation under long-term vertical stress, and ensuring the long-term load-bearing stability of the support. The rubber blocks 3 possess excellent horizontal flexibility and elastic recovery capability; during an earthquake, they can extend the natural period of the building structure through horizontal shear deformation, avoiding the dominant period of the seismic motion and significantly reducing the transmission to the superstructure. Seismic acceleration and seismic force achieve the core horizontal seismic isolation effect. Simultaneously, it can automatically reset the bearings after an earthquake, ensuring the reusability and post-earthquake repairability of the bearings. Addressing the differentiated needs of various building sites based on geological conditions, building structure, load distribution, and seismic fortification levels, the splicing structure 5 enables flexible adjustment and directional optimization of the bearing's seismic isolation performance. This overcomes the limitation of traditional prefabricated seismic isolation bearings where performance cannot be adjusted after finalization. Several through holes 55 are prefabricated on the surfaces of the rubber block 3 and the embedded steel plate 4, serving as a universal reference interface for modular splicing. When it is necessary to improve the bearing's seismic isolation energy dissipation capacity, adapt to higher seismic fortification requirements, or special site conditions, the holes 55 fixed on the inner side of the prefabricated rubber strip 51 are... The steel rod 54 is inserted into the through holes 55 on the surfaces of the rubber block 3 and the steel plate 4. Through the precise fit between the steel rod 54 and the through holes 55, the rubber strip 51 and the main body of the rubber block 3 can be quickly positioned and spliced, completing the addition of a single set of rubber strips 51. This allows for rapid adjustment of the overall stiffness and damping characteristics of the support. When the seismic resistance requirements of the building site are higher and the seismic isolation and load-bearing performance of the support need to be further enhanced, the steel rod 54 of the additional rubber strip 51 can be inserted into the corresponding installation holes 52 on the back side of the rubber strip 51, which are adapted to the size of the steel rod 54. This allows for the multi-level and multi-column continuous splicing and expansion of the rubber strip 51, thereby flexibly adjusting the seismic isolation energy dissipation capacity, vertical load-bearing capacity, and horizontal deformation adaptation capacity of the support. The force allows the support to precisely adapt to the differentiated usage needs of different building sites, greatly improving the support's site adaptability and engineering practicality. After the splicing and installation of the rubber strips 51 are completed, the fixing structure 6 forms a full-enclosed fastening limit for all the added rubber strips 51, ensuring the installation stability of the rubber strips 51 under long-term stress and vibration impact, and avoiding loosening and displacement problems. The fixing structure 6 is based on two L-shaped fixing strips 61, which are symmetrically attached to the diagonal positions of the support body. Together with two U-shaped horizontal frames 62, they form a rectangular ring-shaped encircling structure, completely wrapping all the rubber strips 51 spliced ​​around the outer periphery of the rubber block 3. The horizontal frame 62 is slidably connected to the fixing strips 61 through the slider 69 at the end.The position of the slider 69 and the horizontal frame 62 can be adjusted along the length of the fixing strip 61 according to the overall outer dimensions of the spliced ​​rubber strip 51. This ensures that the inner wall of the horizontal frame 62 is tightly fitted to the outer surface of the rubber strip 51, and can adaptively adapt to the outer dimensions of different layers and quantities of spliced ​​rubber strips 51, achieving flexible adjustment and full fit of the wrap-around structure.

[0047] During the sliding adjustment of slider 69 and horizontal frame 62, positioning block 64 moves synchronously with slider 69. The end of pin 65, which is slidably inserted into positioning block 64, is fixed with a right triangular prism-structured locking block 68 via connecting block 66. Under the elastic tension of spring 67 sleeved on the surface of pin 65, locking block 68 always tends to move towards the groove 63 on the surface of fixing strip 61. When horizontal frame 62 slides to the target locking position against the surface of rubber strip 51, locking block 68 automatically engages with the corresponding groove 63 on the surface of fixing strip 61 under the drive of spring 67. Utilizing the limiting characteristic of the right-angled side of right triangular prism locking block 68, a one-way self-locking structure is formed, restricting the reverse sliding of slider 69 and horizontal frame 62, preventing the circumferential structure from loosening after being subjected to force, and achieving the locking of rubber strip 51. After the rapid pre-tightening and self-locking of the 1st step, the bolt 73, which is threaded into the slider 69, is screwed into the circular groove 74 at the corresponding position on the surface of the horizontal frame 62. Through the precise fit between the bolt 73 and the circular groove 74, a secondary locking limit is formed between the horizontal frame 62 and the slider 69, which completely prevents the horizontal frame 62 from slipping off from the inside of the slider 69 or from shifting. This further enhances the fixing reliability of the circumferential structure, ensuring that the rubber strip 51 and the main body of the rubber block 3 always maintain a tight fit. This effectively prevents the rubber strip 51 from loosening, shifting, or even falling off under long-term vertical load, daily temperature deformation, or seismic vibration impact. It ensures the long-term stability and safety of the structure after the addition of the rubber strip 51, and ensures that the rubber strip 51 can stably participate in the seismic isolation and energy dissipation work of the support under dangerous working conditions.

[0048] Based on the circumferential locking completed by the fixed structure 6, the installation accuracy of the rubber strip 51 is further enhanced by the auxiliary structure 7, which provides additional elastic buffering and energy dissipation damping capacity for the support, forming a collaborative seismic resistance system with the support body. The auxiliary structure 7 includes a first movable block 76 that can slide along the side wall of the L-shaped fixed strip 61, a U-shaped first elastic frame 71 fixedly connected to the first movable block 76, and a second movable block 77 that can slide along the inner groove 75 of the transverse frame 62, and a U-shaped second elastic frame 72 fixedly connected to the second movable block 77. During the installation of the rubber strip 51, the installation accuracy of the rubber strip 51 is further enhanced by the auxiliary structure 7, which provides additional elastic buffering and energy dissipation damping capacity for the support, forming a collaborative seismic resistance system with the support body. The position of the first moving block 76 is adjusted by sliding the strip 61, and the position of the second moving block 77 is adjusted by sliding the groove 75 on the inner side of the horizontal frame 62. This allows the first elastic frame 71 and the second elastic frame 72 of the U-shaped structure to form a stable support with a set spacing on the upper and lower sides of the rubber strip 51. Through the limiting effect of the two elastic frames, the upper and lower sides of the rubber strip 51 can be evenly and flatly attached to the surface of the rubber block 3, avoiding edge warping and loose adhesion of the rubber strip 51 during installation or under stress. This significantly improves the installation positioning accuracy and surface contact stability of the rubber strip 51. At the same time, the U-shaped... The first elastic frame 71 and the second elastic frame 72 of the structure possess excellent elastic deformation capacity and buffer energy absorption characteristics. When the support is subjected to daily vertical load fluctuations, they can adapt to the slight deformation of the rubber block 3 and the rubber strip 51 through their own slight elastic deformation, always maintaining stable support for the rubber strip 51 without affecting the normal load-bearing performance of the support. When an earthquake occurs and the support is subjected to horizontal vibration impact and shear deformation, the first elastic frame 71 and the second elastic frame 72 can generate elastic deformation synchronously with the deformation of the rubber block 3 and the rubber strip 51, absorbing and... It dissipates some of the seismic input energy, shares the energy dissipation pressure of the main body of rubber block 3, and further enhances the overall damping energy dissipation effect of the bearing. On the other hand, it provides an auxiliary reset function for the bearing through elastic restoring force, forming a synergistic reset system with rubber block 3, reducing the residual deformation of the bearing after the earthquake. In addition, the supporting and limiting function of the two elastic frames can effectively constrain the lateral deformation of rubber strip 51, avoiding the problem of rubber strip 51 tearing or detaching under large deformation earthquake action, further improving the structural integrity and seismic reliability of the bearing under extreme working conditions, and comprehensively optimizing the overall seismic isolation and seismic performance of the bearing.

[0049] Under normal operating conditions, the rubber block 3 and the embedded steel plate 4 of the main bearing body bear the main vertical load, while the spliced ​​rubber strip 51 shares the vertical load. The fixed structure 6 and the auxiliary structure 7 together provide stable restraint and support for the rubber strip 51, ensuring the structural stability of the bearing under long-term constant load and live load, and avoiding problems such as creep and loosening. Under extreme conditions of earthquakes, the main body of the rubber block 3 achieves core seismic isolation through horizontal shear deformation, and the added rubber strip 51 participates in shear deformation and energy dissipation, further extending the natural vibration period of the structure and improving the damping energy dissipation capacity. At the same time, the first elastic frame 71 and the second elastic frame 72 are connected. Through its own elastic deformation, the bearing absorbs energy and constrains deformation, forming a multi-level seismic isolation and energy dissipation system with the main body of the bearing. This significantly reduces the seismic force transmitted to the superstructure of the building, comprehensively improving the seismic protection effect of the bearing. For different building sites, this device can flexibly adjust the stiffness, damping, and bearing capacity of the bearing by adjusting the number of rubber strips 51 and the number of splicing layers. With the adaptively adjustable fixed structure 6 and auxiliary structure 7, performance optimization can be completed without replacing the main body of the bearing. It can be widely adapted to the differentiated needs of different scenarios such as soft soil sites, high-intensity seismic fortification zones, and large-load building structures, truly realizing the flexible multi-site adaptation and efficient seismic optimization of the seismic isolation bearing.
