Description

Technical Field

[0001] This invention belongs to the technical field of seismic isolation components for building structures, specifically relating to a wind-resistant and tensile-resistant electromagnetic seismic isolation bearing. Background Technology

[0002] Traditional seismic isolation bearings, under seismic loading, utilize the low horizontal stiffness of the rubber pad to convert the kinetic energy of the earthquake into displacement strain energy within the bearing itself. While this method provides some protection during earthquakes, the inherent tensile properties of the rubber pad result in poor tensile strength. Consequently, traditional seismic isolation bearings are prone to excessive tensile stress and horizontal displacement within the rubber pad, leading to internal structural damage and reduced seismic isolation performance. To improve the tensile strength of seismic isolation bearings, current technology has transformed the traditional solid rubber pad into a layered rubber pad composed of alternating rubber and steel sheets. This significantly enhances the energy dissipation capacity of the bearing and increases horizontal tensile strength by increasing friction, thereby reducing damage to the rubber pad and protecting lives and property. Therefore, developing seismic isolation devices with excellent mechanical properties that are easy to manufacture, process, install, and replace has significant engineering value.

[0003] Currently, seismic isolation devices on the market can be divided into three categories based on bearing type: rubber type, sliding type, and composite type. Rubber type seismic isolation bearings are made of multiple layers of steel plates and rubber alternately stacked. The steel plates act as stiffening materials for the rubber bearings, changing the characteristic of low vertical stiffness of the rubber body, enabling it to reduce horizontal seismic forces while withstanding large vertical loads. Examples of seismic isolation systems include lead-core rubber bearings and laminated rubber bearings. Sliding type seismic isolation bearings incorporate sliding materials, such as low-friction materials like graphite, sand, and talc, within the isolation layer. This allows the foundation to transmit limited seismic forces to the superstructure, thus protecting it. Composite seismic isolation devices combine rubber and sliding types, creating a system with both restoring capacity and energy dissipation characteristics. Examples include parallel use of rubber and sliding bearings, parallel use of rubber bearings and dampers, and composite seismic isolation devices that simultaneously possess elastic horizontal restoring force and damping. However, with increasing structural complexity and the development of prefabricated construction technology, building structures are responding more strongly to earthquakes, placing higher demands on the performance of seismic isolation bearings. Because building structures undergo significant displacement under seismic loads, traditional seismic isolation devices struggle to meet the seismic resistance requirements of building structures. Therefore, it is necessary to develop new types of tensile-resistant seismic isolation bearings.

[0004] Because rubber materials have excellent elastic deformation capabilities, low cost and processing cost, good durability and stable mechanical properties, they are often used to manufacture various types of vibration isolation devices. The vibration isolation mechanism in the vibration isolation device largely determines whether the vibration isolation device can make full use of the excellent mechanical properties of rubber materials.

[0005] Currently, the main components of various seismic isolation devices on the market are rubber materials. However, rubber materials themselves have poor tensile strength, and when buildings are located in high wind pressure and high-intensity earthquake zones, traditional seismic isolation bearings cannot simultaneously meet the requirements for wind resistance and earthquake resistance. Summary of the Invention

[0006] The purpose of this invention is to provide a wind-resistant and tensile-resistant electromagnetic seismic isolation bearing. By utilizing the electromagnetic tensile mechanism, the stiffness of the seismic isolation bearing can be adjusted, thereby enabling the seismic isolation bearing to have both wind-resistant and tensile-resistant properties, which can be used to significantly improve the seismic performance of building structures.

[0007] The specific technical solution adopted by this invention is as follows:

[0008] A wind-resistant and tensile-resistant dual-purpose electromagnetic seismic isolation bearing comprises a tensile electromagnetic component, a wind-resistant electromagnetic component, a laminated rubber seismic isolation bearing, and a tensile outer wall. The two ends of the laminated rubber seismic isolation bearing are fixedly connected to the interior of the tensile outer wall. The wind-resistant electromagnetic component is fixedly connected to one side of the laminated rubber seismic isolation bearing. The tensile outer wall is arranged in an inclined ring around the laminated rubber seismic isolation bearing. The tensile electromagnetic component is fixedly connected to the other side of the laminated rubber seismic isolation bearing.

[0009] The tensile electromagnetic component includes a tensile spring, a tensile electromagnetic assembly, a tensile battery, a tensile electromagnetic induction device, and a tensile battery box. The tensile battery box is fixedly connected to one side of the laminated rubber vibration isolation bearing. The tensile electromagnetic assembly is disposed inside the tensile battery box. Multiple tensile batteries are disposed inside the tensile electromagnetic assembly. Multiple tensile springs are disposed between the tensile electromagnetic assembly and the tensile batteries. The tensile electromagnetic induction device is slidably disposed inside the tensile battery box, and one end of the upper part of the tensile electromagnetic induction device cooperates with the tensile battery.

[0010] In a preferred embodiment, the tensile springs are of unequal length in multiple configurations, and the multiple tensile springs are arranged in a horizontal stepped manner.

[0011] In a preferred embodiment, the interior of the tensile battery box is provided with an I-shaped opening, which mates with the lower end of the tensile electromagnetic induction device.

[0012] In a preferred embodiment, the tensile electromagnetic component has a partition inside that cooperates with the tensile battery box.

[0013] In a preferred embodiment, the wind-resistant electromagnetic component includes a wind-resistant spring, a wind-resistant electromagnetic assembly, a wind-resistant battery, a wind-resistant electromagnetic induction device, and a wind-resistant battery box. The wind-resistant battery box is fixedly connected to the other side of the laminated rubber vibration isolation bearing. The wind-resistant electromagnetic assembly is disposed inside the wind-resistant battery box, the wind-resistant battery is disposed inside the wind-resistant electromagnetic assembly, the wind-resistant spring is disposed between the wind-resistant electromagnetic assembly and the wind-resistant battery, and the wind-resistant electromagnetic induction device is slidably disposed inside the wind-resistant battery box, with one end of the upper part of the wind-resistant electromagnetic induction device cooperating with the wind-resistant battery.

[0014] In a preferred embodiment, the wind-resistant battery box has an I-shaped opening inside, which mates with the lower end of the wind-resistant electromagnetic induction device.

[0015] In a preferred embodiment, the tensile outer wall includes a magnetic guide rod, a tensile electromagnetic block, a rigid cylinder, a wind-resistant electromagnetic ring, and a protective steel sleeve. The magnetic guide rod is initially in contact with the wind-resistant electromagnetic ring, which is placed between two rigid cylinders. The other end of one of the rigid cylinders is connected to the tensile electromagnetic block. The tensile electromagnetic block is electrically connected to the tensile electromagnetic assembly, and the wind-resistant electromagnetic ring is electrically connected to the wind-resistant electromagnetic assembly. The magnetic guide rod, the tensile electromagnetic block, the rigid cylinder, and the wind-resistant electromagnetic ring are all placed inside the protective steel sleeve.

[0016] In a preferred embodiment, one end of the magnetic rod has a permanent magnet, which is placed inside the rigid cylinder and can move freely, while the other end of the magnetic rod is fixedly connected to the tensile outer wall.

[0017] In a preferred embodiment, the rigid cylinder is connected to the wind-resistant electromagnetic induction device, and the wind-resistant electromagnetic induction device is placed between the two rigid cylinders, with the geometric centers of the three cylinders being collinear.

[0018] In a preferred embodiment, a universal joint is provided on the inner side of the tensile outer wall, and the tensile electromagnetic component, the wind-resistant electromagnetic component, and the laminated rubber seismic isolation bearing are connected by the universal joint.

[0019] The technical effects achieved by this invention are as follows:

[0020] The present invention adopts the design of wind-resistant electromagnetic components. When the building faces wind load, the force on the inclined tie rod of the laminated rubber seismic isolation bearing is insufficient to resist the magnetic attraction brought by the wind-resistant electromagnetic ring. Therefore, it can effectively improve the horizontal stiffness of the laminated rubber seismic isolation bearing.

[0021] This invention employs a tensile electromagnetic component design. When a building faces an earthquake, the laminated rubber seismic isolation bearing experiences a large seismic force, causing the attraction force provided by the wind-resistant electromagnetic ring to be insufficient to bear the load, thus resulting in a power outage. The laminated rubber seismic isolation bearing can move freely within a certain horizontal range. When the displacement reaches the restricted area, the tensile electromagnetic component is energized, and a repulsive force is generated between the tensile electromagnet block and the magnetic guide rod, thereby restricting the horizontal displacement of the laminated rubber seismic isolation bearing. When the electromagnetic force is insufficient to bear the seismic force, the magnetic guide rod directly contacts the tensile electromagnet block, thereby utilizing the tensile outer wall to bear the seismic load, ensuring the dual-purpose wind-resistant and tensile-resistant properties of this seismic isolation bearing.

[0022] This invention employs a layered rubber seismic isolation bearing design. When the magnetic rod moves inside the protective steel sleeve, one end of the magnetic rod can switch back and forth between the tensile electromagnetic block and the wind-resistant electromagnetic ring during the movement, thereby achieving the function of switching between wind and seismic resistance.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0036] Please see Figures 1 to 7 As shown, the present invention provides a wind-resistant and tensile-resistant dual-purpose electromagnetic seismic isolation bearing, comprising a tensile electromagnetic component 1, a wind-resistant electromagnetic component 2, a laminated rubber seismic isolation bearing 4, and a tensile outer wall 3. The two ends of the laminated rubber seismic isolation bearing 4 are fixedly connected to the interior of the tensile outer wall 3. The wind-resistant electromagnetic component 2 is fixedly connected to one side of the laminated rubber seismic isolation bearing 4. The tensile outer wall 3 is arranged in an inclined ring around the laminated rubber seismic isolation bearing 4. The tensile electromagnetic component 1 is fixedly connected to the other side of the laminated rubber seismic isolation bearing 4.

[0037] The tensile electromagnetic component 1 includes a tensile spring 101, a tensile electromagnetic assembly 102, a tensile battery 103, a tensile electromagnetic induction device 104, and a tensile battery box 105. The tensile battery box 105 is fixedly connected to one side of the laminated rubber vibration isolation support 4. The tensile electromagnetic assembly 102 is disposed inside the tensile battery box 105. Multiple tensile batteries 103 are disposed inside the tensile electromagnetic assembly 102. Multiple tensile springs 101 are disposed between the tensile electromagnetic assembly 102 and the tensile battery 103. The tensile electromagnetic induction device 104 is slidably disposed inside the tensile battery box 105, and one end of the upper part of the tensile electromagnetic induction device 104 cooperates with the tensile battery 103.

[0038] Specifically, by using the laminated rubber seismic isolation bearing 4 to provide the overall vertical and horizontal initial stiffness of the device, when the building faces wind load, the force on the inclined tie rod of the laminated rubber seismic isolation bearing 4 is insufficient to resist the magnetic attraction brought by the wind-resistant electromagnetic component 2, thus effectively improving the horizontal stiffness of the laminated rubber seismic isolation bearing 4.

[0039] When a building faces an earthquake, the laminated rubber seismic isolation bearing 4 experiences a large seismic force, causing the attraction force provided by the wind-resistant electromagnetic component 2 to be insufficient to bear the load, thus resulting in a power outage. The laminated rubber seismic isolation bearing 4 can move freely within a certain horizontal range. When the displacement reaches the restricted area, the tensile electromagnetic induction device 104 pushes the tensile battery 103 to contact the tensile electromagnetic component 102. At this time, the tensile electromagnetic component 1 is energized, causing a repulsive force to be generated between the tensile electromagnetic component 102 and the tensile electromagnetic induction device 104, thereby restricting the horizontal displacement of the laminated rubber seismic isolation bearing 4. When the electromagnetic force is insufficient to bear the seismic force, the tensile electromagnetic induction device 104 directly contacts the tensile battery box 105, thereby utilizing the overall structural strength of the tensile outer wall 3 to bear the seismic load, ensuring the dual-purpose wind-resistant and tensile-resistant properties of the laminated rubber seismic isolation bearing 4.

[0040] Meanwhile, both the tensile electromagnetic component 1 and the wind-resistant electromagnetic component 2 are placed outside the laminated rubber seismic isolation bearing 4, ensuring the ease of installation and disassembly of the device, and facilitating rapid replacement after an earthquake.

[0041] This fabrication process can be completed in the prefabrication plant, and on-site installation only requires concrete pouring to connect it to the structure. Installation is convenient and quick, and the steel plates are directly fixed by welding, facilitating replacement and inspection after earthquakes.

[0042] Please see Figure 4As shown, at least three tensile springs 101 are provided, and the length of each tensile spring 101 is different. The multiple tensile springs 101 are arranged in a horizontal stepped manner. The tensile springs 101 cooperate with the tensile battery 103. The tensile electromagnetic induction device 104 of the tensile spring 101 is provided with three protruding cylindrical sensing areas. The cylindrical sensing areas cooperate with the tensile battery 103. During the movement of the tensile electromagnetic induction device 104, the cylindrical sensing areas of the tensile electromagnetic induction device 104 can drive the tensile battery 103 to contact the corresponding tensile spring 101 in sequence, which can gradually increase the repulsive force after the tensile electromagnetic component 102 is energized, and realize the automatic adjustment of the stepped increase of the repulsive force of the tensile electromagnetic component 102 when energized.

[0043] Please see Figure 3 As shown, the interior of the tensile battery box 105 is provided with an I-shaped opening, which cooperates with the lower end of the tensile electromagnetic induction device 104. The I-shaped opening provides guidance and limit for the tensile electromagnetic induction device 104, thereby improving the stability of the tensile electromagnetic induction device 104 when it moves.

[0044] Please see Figure 3 and Figure 4 As shown, the tensile electromagnetic component 102 has a partition inside that cooperates with the tensile battery box 105. The partition provides a limit for the tensile battery 103 inside the tensile battery box 105, preventing the tensile battery 103 from shifting during movement.

[0045] Please see Figure 5 and Figure 6 As shown, the wind-resistant electromagnetic component 2 includes a wind-resistant spring 201, a wind-resistant electromagnetic assembly 202, a wind-resistant battery 203, a wind-resistant electromagnetic induction device 204, and a wind-resistant battery box 205. The wind-resistant battery box 205 is fixedly connected to the other side of the laminated rubber vibration isolation support 4. The wind-resistant electromagnetic assembly 202 is disposed inside the wind-resistant battery box 205, the wind-resistant battery 203 is disposed inside the wind-resistant electromagnetic assembly 202, and the wind-resistant spring 201 is disposed between the wind-resistant electromagnetic assembly 202 and the wind-resistant battery 203. The wind-resistant spring 201 can prevent excessive compression. The wind-resistant battery 203 is pressed, and the wind-resistant electromagnetic induction device 204 is slidably disposed inside the wind-resistant battery box 205. One end of the wind-resistant electromagnetic induction device 204 is engaged with the wind-resistant battery 203. The movement of the wind-resistant electromagnetic induction device 204 can make the wind-resistant battery 203 contact with the wind-resistant electromagnetic component 202 to supply power. The protruding cylindrical induction area of ​​the wind-resistant electromagnetic induction device 204 is in contact with the electrode of the wind-resistant battery 203, and it will disengage as the force on the seismic isolation support increases, thereby de-energizing the wind-resistant electromagnetic ring and achieving wind and seismic resistance transformation.

[0046] Please see Figure 5As shown, the wind-resistant battery box 205 has an I-shaped opening inside, which cooperates with the lower end of the wind-resistant electromagnetic induction device 204. The I-shaped opening provides guidance and limit for the tensile electromagnetic induction device 104, improving the stability of the wind-resistant electromagnetic induction device 204 when it moves.

[0047] Please see Figure 7 As shown, the tensile outer wall 3 includes a magnetic guide rod 301, a tensile electromagnetic block 302, a rigid cylinder 303, a wind-resistant electromagnetic ring 304, and a protective steel sleeve 305. The magnetic guide rod 301 is initially in contact with the wind-resistant electromagnetic ring 304, which is positioned between two rigid cylinders 303. The other end of one of the rigid cylinders 303 is connected to the tensile electromagnetic block 302. The tensile electromagnetic block 302 is electrically connected to the tensile electromagnetic assembly 102, and the wind-resistant electromagnetic ring 304 is electrically connected to the wind-resistant electromagnetic assembly 202. The magnetic guide rod 301, the tensile electromagnetic block 302, the rigid cylinder 303, the wind-resistant electromagnetic ring 304, and the protective steel sleeve 305 are all connected in this configuration. The magnetic block 302, the rigid cylinder 303, and the wind-resistant electromagnetic ring 304 are all placed inside the protective steel sleeve 305. The outside of the protective steel sleeve 305 and the guide rod part of the corresponding magnetic guide rod 301 are connected to the wind-resistant electromagnetic induction device 204 and the tensile electromagnetic induction device 104 through a rigid component. When the magnetic guide rod 301 moves inside the protective steel sleeve 305, one end of the magnetic guide rod 301 can switch back and forth between the tensile electromagnetic block 302 and the wind-resistant electromagnetic ring 304 during the movement, thereby realizing the wind-resistant and earthquake-resistant switching function.

[0048] Please see Figure 7 As shown, one end of the magnetic rod 301 has a permanent magnet, which is placed inside the rigid cylinder 303 and can move freely. The other end of the magnetic rod 301 is fixedly connected to the tensile outer wall 3. When the electromagnetic force is insufficient to bear the seismic force, one end of the magnetic rod 301 directly contacts the tensile electromagnetic block 302, thereby using the tensile outer wall 3 to absorb the seismic load.

[0049] Please see Figure 7 As shown, the rigid cylinder 303 is connected to the wind-resistant electromagnetic ring 304, and the wind-resistant electromagnetic ring 304 is placed between the two rigid cylinders 303, with the geometric centers of the three remaining collinear.

[0050] Please see Figure 7 As shown, a universal hinge 401 is provided on the inner side of the tensile outer wall 3. The tensile electromagnetic component 1, the wind-resistant electromagnetic component 2 and the laminated rubber vibration isolation support 4 are connected through the universal hinge 401. The universal hinge 401 can ensure that the equipment can move at any angle, increasing the practicality of the equipment.

[0051] The working principle of this invention is as follows: by using the laminated rubber seismic isolation bearing 4 to provide the overall vertical initial stiffness and horizontal initial stiffness of the device, when the building faces wind load, the force on the inclined tie rod of the laminated rubber seismic isolation bearing 4 is insufficient to resist the magnetic attraction brought by the wind-resistant electromagnetic component 2, thus effectively improving the horizontal stiffness of the laminated rubber seismic isolation bearing 4.

[0052] When a building faces an earthquake, the laminated rubber seismic isolation bearing 4 experiences a large seismic force, causing the attraction force provided by the wind-resistant electromagnetic component 2 to be insufficient to bear the load, thus resulting in a power outage. The laminated rubber seismic isolation bearing 4 can move freely within a certain horizontal range. When the displacement reaches the restricted area, the wind-resistant electromagnetic component 2 is energized, and a repulsive force is generated between the tensile electromagnetic component 102 and the tensile electromagnetic induction device 104, thereby restricting the horizontal displacement of the laminated rubber seismic isolation bearing 4. When the electromagnetic force is insufficient to bear the seismic force, the tensile electromagnetic induction device 104 directly contacts the tensile battery box 105, thereby utilizing the overall structural strength of the tensile outer wall 3 to bear the seismic load, ensuring the dual-purpose wind-resistant and tensile-resistant properties of the laminated rubber seismic isolation bearing 4.

[0053] Meanwhile, both the tensile electromagnetic component 1 and the wind-resistant electromagnetic component 2 are placed outside the laminated rubber seismic isolation bearing 4, ensuring the ease of installation and disassembly of the device, and facilitating rapid replacement after an earthquake.

[0054] This fabrication process can be completed in the prefabrication plant, and on-site installation only requires concrete pouring to connect it to the structure. Installation is convenient and quick, and the steel plates are directly fixed by welding, facilitating replacement and inspection after earthquakes.
