Description

Technical Field

[0001] The invention relates to the technical field of seismic isolation bearings, and in particular to a building seismic isolation bearing connection node and a construction method thereof. Background Art

[0002] During building design and construction, seismic isolation bearings are often installed at the bottom of the building structure to improve the seismic performance of the building structure.

[0003] The rubber material itself has certain elasticity and seismic resistance, and has a long service life. It is not easily corroded and worn by the external environment, and has relatively low maintenance costs. It can effectively reduce the degree to which the building structure is affected by external vibrations and improve the seismic performance of the building. Therefore, rubber seismic isolation bearings are often used in the prior art. They have a simple structure and are easy to install, and the installation work can be completed in a shorter time.

[0004] However, due to the relatively small bearing capacity of rubber materials and limited scope of application, rubber seismic isolation bearings are not suitable for the seismic isolation bearing design of large buildings or heavy-loaded structures. In addition, there are two forms of impact directions of earthquake waves, one is vertical and the other is horizontal; rubber seismic isolation bearings have a good seismic isolation and shock absorption effect on the impact force in the vertical direction, but the seismic isolation and shock absorption effect on the impact force in the horizontal direction is relatively weak.

[0005] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Summary of the invention

[0058] Embodiment 1:

[0059] In order to solve the above problems, Figure 1 As shown, an embodiment of the present invention provides a building seismic isolation bearing connection node, the building seismic isolation bearing connection node includes a building seismic isolation bearing, the building seismic isolation bearing is arranged on a foundation, the building seismic isolation bearing bears a building structure to constitute a building seismic isolation bearing connection node; wherein, the building seismic isolation bearing includes an upper fixed plate 1, an upper support plate 2, a lower fixed plate 3, a lower support plate 4 and a slider 5.

[0060] The upper fixing plate 1 is fixed on the upper supporting plate 2 , and the upper fixing plate 1 bears the building structure. The lower fixing plate 3 is arranged on the foundation, and the lower supporting plate 4 is fixed on the lower fixing plate 3 .

[0061] The slider 5 is slidably arranged between the upper support plate 2 and the lower support plate 4, the upper surface shape of the slider 5 matches the inner shape of the upper support plate 2, the lower surface shape of the slider 5 matches the inner shape of the lower support plate 4, and the inner side of the upper support plate 2 abuts against the upper surface of the slider 5, and the inner side of the lower support plate 4 abuts against the lower surface of the slider 5.

[0062] A sliding space is formed between the upper support plate 2 and the lower support plate 4. When an earthquake occurs, the slider 5 slides in the sliding space to dislocate the upper support plate 2 and the lower support plate 4.

[0063] like Figure 1 The figure shows a specific example of a building seismic isolation support in a static state (i.e., when no earthquake occurs); at this time, the relative positions of the upper support plate 2 and the lower support plate 4 in the horizontal direction remain unchanged, that is, the upper support plate 2 and the lower support plate 4 are relatively static, and the upper support plate 2 is supported by the slider 5; it should be noted that Figure 1 The parts above the building structure and below the foundation are not fully shown and are omitted using broken lines.

[0064] The building seismic isolation bearing is installed on the foundation, and the buildings are all built on the building seismic isolation bearing. When an earthquake occurs, under the action of the seismic force, the foundation will be affected by the horizontal earthquake shock wave, and the corresponding horizontal impact force will cause the slider 5 to slide in the sliding space, that is, the slider 5 will change its relative position with the foundation and the lower support plate 4, so that the lower support plate 4 and the upper support plate 2 are relatively staggered. Among them, the upper support plate 2 basically does not move with the movement of the foundation to reduce the impact of the earthquake on the building.

[0065] Due to the existence of the slider 5 and the sliding space, the impact force of the seismic wave transmitted by the building isolation bearing of the embodiment of the present invention to the upper building structure is weakened, so the building structure can be protected when an earthquake occurs. Among them, the present invention uses the slider 5 to reduce the impact force in the horizontal direction, improves the structural integrity at the connection node, and solves the problem that the rubber isolation bearing is not suitable for large buildings or heavy-loaded structures and has a weak isolation and shock absorption effect on the impact force in the horizontal direction.

[0066] In addition, there is friction work between the upper end of the slider 5 and the inner side of the upper support plate 2, and between the lower end of the slider 5 and the inner side of the lower support plate 4. The friction work consumes the vibration energy of the building structure brought by the seismic waves, reduces the structural seismic response, and achieves the effect of reducing the damage to the building caused by the seismic waves.

[0067] In order to facilitate the sliding of the slider 5, in one embodiment, as Figure 2 As shown, the upper end of the slider 5 is provided with an upper sliding panel 52, the surface shape of the upper sliding panel 52 matches the inner shape of the upper support plate 2, and the upper sliding panel 52 abuts against the inner side of the upper support plate 2; the lower end of the slider 5 is provided with a lower sliding panel 53, the surface shape of the lower sliding panel 53 matches the inner shape of the lower support plate 4, and the lower sliding panel 53 abuts against the inner side of the lower support plate 4.

[0068] In an optional embodiment, the upper sliding panel 52 and the lower sliding panel 53 may be made of a non-metallic high-strength compound material.

[0069] In order to match the upper sliding panel 52 and the lower sliding panel 53, as shown in FIG. Figure 2 As shown, an upper spherical slide 21 is provided on the inner side of the upper support plate 2; a lower spherical slide 41 is provided on the inner side of the lower support plate 4; when an earthquake occurs, the upper sliding panel 52 slides on the upper spherical slide 21, and the lower sliding panel 53 slides on the lower spherical slide 41, so as to dislocate the upper support plate 2 and the lower support plate 4.

[0070] Among them, the friction coefficient between the upper sliding panel 52 and the upper spherical slide 21, and the friction coefficient between the lower sliding panel 53 and the lower spherical slide 41 should be small in principle, so that the relative position of the sliding block 5 and the lower support plate 4 changes, thereby achieving the purpose of reducing the seismic force transmitted to the upper support plate 2; the friction coefficient between the upper sliding panel 52 and the upper spherical slide 21, and the friction coefficient between the lower sliding panel 53 and the lower spherical slide 41 are determined by technical personnel in this field according to the specific usage scenario.

[0071] In an optional embodiment, the upper spherical slideway 21 and the lower spherical slideway 41 may be made of metal material.

[0072] Embodiment 2:

[0073] Based on Example 1 of the present invention, this embodiment provides a construction method for connecting nodes of building seismic isolation bearings, such as Figure 3 Specifically, it includes:

[0074] Step 10: Fix the upper fixing plate 1 on the upper support plate 2 ; fix the lower support plate 4 on the lower fixing plate 3 .

[0075] The upper fixing plate 1 and the upper support plate 2 are fixed in advance to obtain a first integral body formed by the upper fixing plate 1 and the upper support plate 2; and the lower support plate 4 and the lower fixing plate 3 are fixed to obtain a second integral body formed by the lower fixing plate 3 and the lower support plate 4.

[0076] Step 20: The slider 5 is disposed between the upper support plate 2 and the lower support plate 4 so that the inner side of the upper support plate 2 abuts against the upper surface of the slider 5 , and the inner side of the lower support plate 4 abuts against the lower surface of the slider 5 .

[0077] Then install the first whole, the slider 5 and the second whole.

[0078] Step 30: Use multiple groups of anchoring assemblies to install the lower fixing plate 3 on the foundation.

[0079] In an optional embodiment, other connecting parts may be used to replace the anchoring assembly to firmly mount the lower fixing plate 3 on the foundation, so as to fix the building seismic isolation bearing formed by the first whole, the slider 5 and the second whole in the foundation through the lower fixing plate 3.

[0080] Step 40: Use multiple groups of anchoring components to connect the upper end of the upper fixing plate 1 to the floor of the building structure.

[0081] In one embodiment, in combination with actual on-site conditions, the building seismic isolation bearing according to the embodiment of the present invention can be installed by hoisting with an on-site tower crane.

[0082] After installing the building seismic isolation bearing of the embodiment of the present invention, when an earthquake occurs, since the slider 5 will continuously slide between the upper bearing plate 2 and the lower bearing plate 4, the setting of the slider 5 weakens the force transmitted to the upper bearing plate 2, compared with the direct connection between the foundation and the building structure, so that the relative position change of the upper bearing plate 2 in the horizontal direction is reduced, so that the back-and-forth swing amplitude of the building structure relative to the foundation in the horizontal direction can be reduced as much as possible, thereby reducing the impact of the earthquake on the upper building structure.

[0083] like Figure 4 The figure shows a top view of a specific example of installing an array of building seismic isolation bearings on a foundation, on which a plurality of building seismic isolation bearings are installed in an array. In one embodiment, 16 building seismic isolation bearings in a 4*4 arrangement can be installed on the foundation, and the building seismic isolation bearings are arranged at locations with greater stress in the building structure to ensure that they can fully exert their seismic isolation effects; the specific installation position of the building seismic isolation bearings on the foundation is selected by those skilled in the art according to the specific usage scenario.

[0084] Embodiment 3:

[0085] Based on the third embodiment of the present invention, this embodiment provides a construction method for connecting nodes of seismic isolation bearings of a building, such as Figure 5 Specifically, it includes:

[0086] Before the slider 5 is arranged between the upper support plate 2 and the lower support plate 4, the method further includes:

[0087] Step 501: multiple upper electromagnets 11 are arranged in the upper fixed plate 1, and the wires of the upper electromagnets 11 are led out from the upper fixed plate 1; wherein the multiple upper electromagnets 11 are distributed in an array.

[0088] Step 502: multiple lower electromagnets 31 are arranged in the lower fixing plate 3, and the wires of the lower electromagnets 31 are led out from the lower fixing plate 3; wherein the multiple lower electromagnets 31 are distributed in an array.

[0089] Step 503 : a steel plate 51 is arranged in the slider 5 .

[0090] The following is an example of the process of installing the upper electromagnet 11 and reserving the wire for it, and the installation process is described; the process of installing the lower electromagnet 31 and reserving the wire for it is similar, and will not be repeated here; Figure 6 As shown, a plurality of upper electromagnets 11 are arranged in the upper fixing plate 1, and the wires of the upper electromagnets 11 are led out from the upper fixing plate 1, including:

[0091] Step 5011 : Determine the installation positions of the plurality of upper electromagnets 11 on the upper fixing plate 1 according to the spacing threshold between each of the upper electromagnets 11 .

[0092] The spacing threshold is the minimum distance at which the magnetic fields of adjacent electromagnets do not affect each other, and the spacing threshold is selected by those skilled in the art according to a specific usage scenario.

[0093] Step 5012: Use fasteners to fix the upper electromagnet 11 to the corresponding installation position.

[0094] In an optional embodiment, other connecting members may be used instead of fasteners to fix the electromagnet.

[0095] Step 5013: Connect the wires to the upper electromagnet 11 according to a preset wiring method, and lead the wires of the upper electromagnet 11 out of the upper fixing plate 1 .

[0096] The preset wiring mode is selected by those skilled in the art according to the specific usage scenario and is not limited here. In one embodiment, the wires can be connected to the wiring terminals of the electromagnet.

[0097] After the installation is completed, the upper electromagnet 11 and the lower electromagnet 31 are powered. Specifically, after the upper end of the upper fixing plate 1 is connected to the floor of the building structure using multiple sets of anchoring components, the following steps are also included:

[0098] The plurality of upper electromagnets 11 are powered by wires led out from the upper fixed plate 1; the plurality of lower electromagnets 31 are powered by wires led out from the lower fixed plate 3, so as to apply a first voltage to each of the upper electromagnets 11 and the lower electromagnets 31, so as to generate magnetic flux lines between the upper electromagnets 11 and the corresponding lower electromagnets 31 when an earthquake occurs; the position of the steel plate 51 in the sliding space is determined based on the induced current of the power supply lines corresponding to each upper electromagnet 11 and each lower electromagnet 31; the relative position change between the upper bearing plate 2 and the lower bearing plate 4 of each building seismic isolation bearing is determined based on the position of the steel plate 51 in the sliding space, so as to identify the aged building seismic isolation bearing and prompt the replacement of the aged building seismic isolation bearing.

[0099] In one embodiment, the aged building seismic isolation bearings may be determined and prompted in the manner described in Embodiment 4.

[0100] Embodiment 4:

[0101] After a certain number of years of use, the contact surface between the slider 5 and the upper support plate 2 and the lower support plate 4 will age, which will hinder the sliding of the slider 5. As a result, when an earthquake occurs, the building structure supported by the building isolation support will swing back and forth with respect to the foundation more, affecting the shock absorption effect. Specifically, Figure 2 As shown, since the upper sliding panel 52 and the lower sliding panel 53 are often made of non-metallic high-strength compound materials, and the upper spherical slideway 21 and the lower spherical slideway 41 are often made of metal materials, there will be wear between the upper sliding panel 52 and the upper spherical slideway 21, and there will be wear between the lower sliding panel 53 and the lower spherical slideway 41; when an earthquake occurs, the friction caused by the wear will hinder the sliding of the slider 5. For example, in an actual application scenario, since the sliding direction of the slider 5 in the sliding space is roughly the same when an earthquake occurs, the wear angle of the upper spherical slideway 21 on the upper sliding panel 52 and the wear angle of the lower spherical slideway 41 on the lower sliding panel 53 of the building seismic isolation bearing are also roughly the same when the earthquake occurs; after the building seismic isolation bearing has experienced several earthquakes, some angles of the upper sliding panel 52 and the lower sliding panel 53 are likely to be worn to a greater extent. When an earthquake occurs again, the slider 5 will slide in the sliding space. If the sliding direction is different from the angle of wear of the slider 5 at this time, the wear of the corresponding angle will hinder the sliding of the slider 5.

[0102] In addition, the upper sliding panel 52 and the lower sliding panel 53 are non-metallic materials, and may crack after aging or being used in multiple earthquakes, which will also hinder the sliding of the slider 5 when an earthquake occurs.

[0103] like Figure 4As shown, a plurality of building seismic isolation bearings are often installed on the foundation of a building structure; when the aging degree of each building seismic isolation bearing under the building structure is inconsistent, when an earthquake occurs, the sliding amplitudes of the sliders 5 in each building seismic isolation bearing vary greatly, resulting in large differences in the swing amplitudes of various parts of the building structure carried by each building seismic isolation bearing, which seriously affects the shock absorption effect and causes the earthquake to cause greater damage to the building structure.

[0104] In order to solve the above problems and ensure the shock absorption effect of the seismic isolation bearing, this embodiment also provides a solution for detecting whether the building seismic isolation bearing is aged. Specifically, Figure 7 As shown, the upper fixed plate 1 is provided with a plurality of upper electromagnets 11, which are distributed in an array; the lower fixed plate 3 is provided with a plurality of lower electromagnets 31, which are distributed in an array; and the slider 5 is provided with a steel plate 51.

[0105] The specific number and installation positions of the upper electromagnets 11 in the upper fixing plate 1 and the lower electromagnets 31 in the lower fixing plate 3 are selected by those skilled in the art according to the specific usage scenario. In an optional embodiment, the electromagnets can be distributed as much as possible on the lower fixing plate 3 of the upper fixing plate 1 while ensuring that the magnetic fields of the adjacent electromagnets do not affect each other.

[0106] After the upper electromagnet 11 and the lower electromagnet 31 are powered on, magnetic flux lines are generated; the steel plate 51 acts as a conductor to cut the magnetic flux lines to detect the aging of the building seismic isolation bearings.

[0107] In this embodiment, a plurality of upper electromagnets 11 are arranged in the upper fixing plate 1, a plurality of lower electromagnets 31 are arranged in the lower fixing plate 3, and a steel plate 51 is arranged in the slider 5. Figure 8 As shown, when an earthquake occurs, when the upper fixed plate 1 and the lower fixed plate 3 change their relative positions in the horizontal direction, since the upper electromagnet 11 and the lower electromagnet 31 are both in the energized state, an electromagnetic field will be formed between each upper electromagnet 11 and the lower electromagnet 31 at the corresponding position, and corresponding magnetic flux lines will be generated. In the vertical direction, the steel plate 51 between the upper electromagnet 11 and the lower electromagnet 31 will cut a number of magnetic flux lines as a conductor. The embodiment of the present invention detects whether the building seismic isolation bearing is aged by the voltage change of the electromagnet.

[0108] Specifically, Fig. 9As shown, it is a schematic diagram of the power supply lines of each upper electromagnet 11 and each lower electromagnet 31. Corresponding sensors are pre-arranged on the power supply lines of each upper electromagnet 11 and each lower electromagnet 31, that is, each electromagnet corresponds to a sensor, and the sensor is used to collect the voltage change on the power supply line of the corresponding electromagnet to determine the induced current corresponding to the power supply line of each electromagnet, and then determine the relative position change of the upper support plate 2 and the lower support plate 4 of each building seismic isolation support according to the induced current, so as to realize the detection of the aging condition of the building seismic isolation support. Fig. 9 The sensor and the corresponding power supply circuit are not shown. A sensor power supply voltage is applied to the sensor; wherein the sensor power supply voltage is less than 36 volts, and the specific value of the sensor power supply voltage is selected by those skilled in the art according to the specific usage scenario.

[0109] After the multiple upper electromagnets 11 and the multiple lower electromagnets 31 are powered on, magnetic flux lines are generated between the upper electromagnets 11 and the corresponding lower electromagnets 31, and the steel plate 51 acts as a conductor to cut the magnetic flux lines. At this time, for the electromagnets corresponding to the magnetic flux lines cut by the steel plate 51, their own induced currents will also be affected by the electromagnetic field. Therefore, when an earthquake occurs, this embodiment acquires the change of the induced current by collecting the voltage change on the power supply line, and then determines the current position of the slider 5 in the sliding space. Specifically, a first voltage is applied to each upper electromagnet 11 and each lower electromagnet 31, and the voltage range of the first voltage is 5 volts to 12 volts. At this time, the corresponding electromagnets generate an electromagnetic field, and the steel plate 51 moves in the electromagnetic field to cut the magnetic flux lines. Since the voltage value of the first voltage is small, the electromagnetic damping generated by the movement of cutting the magnetic flux lines has a very weak effect on the position of the steel plate 51 in the sliding space and can be ignored. In an optional embodiment, the voltage value of the first voltage can be selected based on the mass of the steel plate 51 to minimize the effect of the electromagnetic damping generated by the movement of cutting the magnetic flux lines on the position of the steel plate 51 in the sliding space.

[0110] The voltage change of each electromagnet is collected by the sensor to determine the position of the slider 5 in each building isolation support under the building structure when an earthquake occurs. Figure 4 The figure shows a top view of 16 building seismic isolation supports, where the upper fixing plate 1 and the lower fixing plate 3 are rectangular, and the corresponding upper electromagnets 11 and lower electromagnets 31 are arranged in an array in the rectangular space. Figure 4 The 16 building seismic isolation bearings shown in the figure are then analyzed to find out the building seismic isolation bearings whose shock absorption effects are quite different from those of most other building seismic isolation bearings; for the same earthquake, the building seismic isolation bearings with quite different shock absorption effects are likely to have material aging problems.

[0111] In one embodiment, the building seismic isolation supports with large differences in shock absorption effects may be determined in the following manner to detect whether the building seismic isolation supports are aged:

[0112] like Fig. 9 The figure shows a specific example schematic diagram of the positional relationship between the electromagnet and the steel plate 51 when there is no earthquake. The magnetic flux lines cut by the steel plate 51 can be determined based on the induced current obtained above, and the position of the electromagnet that generates the magnetic flux lines can be used to calibrate the position of the steel plate 51 in the sliding space.

[0113] When an earthquake occurs, power is supplied to the multiple electromagnets in the building isolation support to apply a first voltage to each upper electromagnet 11 and the lower electromagnet 31, so that each upper electromagnet 11 and the corresponding lower electromagnet 31 generate magnetic flux lines; the data detected by the sensor is acquired in real time to determine the change of the induced current of each electromagnet, and the reference position of the steel plate when the earthquake occurs is determined according to the change of the induced current; during the earthquake, the change of the induced current of each electromagnet continues to be acquired in real time to determine the real-time position of the steel plate, and then the relative position change between the upper fixed plate 1 and the lower fixed plate 3 is determined according to the real-time position and the reference position.

[0114] For example, Fig. 9 As shown in the dotted box, the reference position of the steel plate 51 can be calibrated using the positions of the following electromagnets: the 4th, 5th and 6th upper electromagnets 11 from left to right in the upper fixed plate 1, and the 4th, 5th and 6th lower electromagnets 31 from left to right in the lower fixed plate 3. Fig.10 : is a schematic diagram of a specific example of an electromagnet affected by an electromagnetic field when an earthquake occurs, provided by an embodiment of the present invention. When an earthquake occurs, the slider 5 is affected by the earthquake shock wave and will slide in the sliding space. If the corresponding contact surface is aged, it will hinder the sliding of the slider 5. At this time, the position of the steel plate 51 after sliding is calibrated by the position of the electromagnet below: Fig.10 As shown in the dotted box, the 3rd, 4th and 5th upper electromagnets 11 from left to right in the upper fixed plate 1, and the 6th, 7th and 8th lower electromagnets 31 from left to right in the lower fixed plate 3, in the upper fixed plate 1 and the lower fixed plate 3, respectively, according to the corresponding reference positions, take a single electromagnet as a unit, and calculate the relative position change between the upper fixed plate 1 and the lower fixed plate 3; since the affected upper electromagnet 11 in the upper fixed plate 1 moves 1 unit to the left, and the affected lower electromagnet in the lower fixed plate 3 moves 2 units to the right, the relative position change between the upper fixed plate 1 and the lower fixed plate 3 is 3 units.

[0115] According to the above method, the relative position change between the upper fixing plate 1 and the lower fixing plate 3 in each building seismic isolation support is determined.

[0116] Then, if the relative position change of a building seismic isolation bearing is not within the design range, it is determined to be an aged building seismic isolation bearing, and a prompt is given to replace the aged building seismic isolation bearing. The design range may be: the relative position change is within 4 units.

[0117] Secondly, for the same earthquake, when the ratio of the number of building seismic isolation bearings with the same relative position change (for example, the relative position change is 3 units) to the total number of building seismic isolation bearings under the building structure exceeds the first proportional threshold, the building seismic isolation bearings with different relative position changes (for example, the relative position change is 4 units) will be determined as building seismic isolation bearings with larger differences in shock absorption effects; among which, the first proportional threshold is determined by technical personnel in this field according to the specific usage scenario, and the first proportional threshold may be 2 / 3.

[0118] When the aging degree of the building seismic isolation bearings is within the design range and meets the requirements corresponding to the service life, an error range can also be set; for example, when the ratio of the number of building seismic isolation bearings whose relative position changes are all within the preset change range to the total number of building seismic isolation bearings under the building structure exceeds the first proportion threshold, the building seismic isolation bearings with different relative position changes (for example, the relative position change is 5 units) will be determined as building seismic isolation bearings with larger differences in shock absorption effects; wherein, the preset change range is determined by technical personnel in this field according to the specific usage scenario, and the preset change range can be 2 units to 3 units.

[0119] For building seismic isolation bearings with large differences in shock absorption effects, if their aging degree is not within the design range and does not meet the corresponding requirements for the service life, it will seriously affect the seismic resistance level of the building structure. The aging building seismic isolation bearings need to be replaced immediately to ensure that the swing amplitude of the building structure during an earthquake is as consistent as possible, thereby reducing the damage to the building structure caused by the earthquake.

[0120] Embodiment 5:

[0121] When an earthquake occurs, the solutions in Example 3 and Example 4 are first used to determine the aged building isolation bearings. If the aging degree of the aged building isolation bearings is within the design range and meets the requirements corresponding to the service life, or if it is necessary to replace the aged building isolation bearings but new building isolation bearings and accessories have not yet been purchased, before replacing the building isolation bearings, this embodiment provides a solution to ensure that the swing amplitude of the building structure during an earthquake is as consistent as possible, so as to further reduce the impact on the building structure.

[0122] In one embodiment, a second voltage is applied to each of the upper electromagnets 11 and the lower electromagnets 31, and after the upper electromagnets 11 and the lower electromagnets 31 are powered on, magnetic flux lines are generated; the steel plate 51 acts as a conductor to cut the magnetic flux lines and generate damping, so that the movement speed of the slider 5 is slowed down to reduce the movement of the upper support plate 2 relative to the lower support plate 4. Different second voltages are applied according to the aging degree of different building isolation bearings, so that the relative position change between the upper fixed plate 1 and the lower fixed plate 3 in each building isolation bearing is basically consistent, so that the building remains basically motionless or the swing amplitude is as consistent as possible.

[0123] Among them, the voltage range of the second voltage is 60 volts to 290 volts, and the specific voltage value of the second voltage is determined by technical personnel in this field according to specific usage scenarios and experience.

[0124] In one embodiment, assuming that there is a building isolation support with a large relative movement displacement, when an earthquake occurs, an electromagnetic field is formed between the upper electromagnet 11 and the corresponding lower electromagnet 31 in the vertical direction, generating corresponding magnetic flux lines, and under the influence of the earthquake wave and friction, the slider 5 slides in the sliding space; the steel plate 51 in the slider 5 acts as a conductor to cut the magnetic flux lines, thereby generating damping, which slows down the movement speed of the slider 5, thereby further reducing the relative movement displacement, so that the swing amplitudes of all building isolation supports are as consistent as possible.

[0125] It should be noted that after the second voltage is applied to the electromagnet, the shock-absorbing effect of each building isolation support may be slightly deteriorated, but the swing amplitude of all building isolation supports can be ensured to be as consistent as possible to avoid building cracks.

[0126] In one embodiment, for the same earthquake, when the ratio of the number of building seismic isolation bearings with large differences in seismic absorption effects to the total number of all building seismic isolation bearings under the building structure does not exceed a second ratio threshold, the building seismic isolation bearings with large differences in seismic absorption effects are directly replaced; wherein the second ratio threshold is determined by technical personnel in this field according to the specific usage scenario, and the second ratio threshold may be 1 / 8.

[0127] In one embodiment, based on the difference in shock absorption effect (i.e., the difference in relative movement change), the aging degree of each building isolation support is marked, and a mapping relationship between the aging degree and the voltage magnitude is established, so that the building isolation supports with different aging degrees are differentially pressurized according to the mapping relationship, so that the magnetic field strength generated by the electromagnets in all the building isolation supports under the building structure is different. In the building isolation support with a lower aging degree, by applying a second voltage with a larger voltage value (for example, 220 volts), a relatively large electromagnetic damping is generated when the steel plate 51 cuts the magnetic flux lines of the corresponding electromagnetic field; for the building isolation support with a higher aging degree, by applying a second voltage with a smaller voltage value, a relatively small electromagnetic damping is generated when the steel plate 51 cuts the magnetic flux lines of the corresponding electromagnetic field, or the electromagnetic damping generated by the steel plate 51 cutting the magnetic flux lines has a negligible effect on the position of the steel plate 51 in the sliding space. By applying a second voltage of corresponding magnitude according to different aging degrees, the movement speed of the steel plate 51 in the building isolation support with a lower aging degree is slowed down, and the relative movement displacement of the building isolation support with a lower aging degree is reduced. By making the building seismic isolation bearing with a lower degree of aging produce electromagnetic damping, the electromagnetic damping is used to balance the friction force of the slider 5 in the building seismic isolation bearing with a higher degree of aging when it slides, so that the resistance encountered by the slider 5 in the building seismic isolation bearing under the building structure is as consistent as possible, thereby ensuring that the swing amplitude of the building structure during an earthquake is as consistent as possible, thereby reducing the damage to the building structure caused by the earthquake.

[0128] On this basis, in an optional embodiment, for a certain specified relative position change (for example, 3 units), the number of building seismic isolation supports whose corresponding relative position change is the same as the specified relative position change is determined as a first number; and a first ratio of the first number to the total number of all building seismic isolation supports under the building structure is determined. When the first ratio exceeds the first ratio threshold, for building seismic isolation supports whose corresponding relative position change (for example, 1 unit) is less than the specified relative position change, or for building seismic isolation supports whose corresponding relative position change is less than a preset change range (for example, 2 units to 3 units), compared with the second voltage applied to the building seismic isolation supports corresponding to the specified relative position change, a larger second voltage can be applied to the building seismic isolation supports whose relative position change is less than the specified relative position change, or the current can be increased, so as to increase the electromagnetic damping generated by the building seismic isolation supports whose relative position change is less than the specified relative position change when an earthquake occurs, so that the swing amplitude is as consistent as possible. When the first ratio exceeds the first ratio threshold, for the building seismic isolation bearing whose corresponding relative position change (for example, 4 units) is greater than the specified relative position change, or for the building seismic isolation bearing whose corresponding relative position change is greater than a preset change range (for example, 2 units to 3 units), compared with the second voltage applied to the building seismic isolation bearing corresponding to the specified relative position change, a smaller second voltage can be applied to the building seismic isolation bearing whose relative position change is greater than the specified relative position change, or its current can be reduced, so as to reduce the electromagnetic damping generated by the building seismic isolation bearing whose relative position change is greater than the specified relative position change when an earthquake occurs, thereby making the swing amplitude of the building seismic isolation bearing under the building structure as consistent as possible.

[0129] Embodiment 6:

[0130] On the basis of the above embodiment, when an earthquake occurs, if the earthquake level is large, the foundation may be greatly affected by the earthquake shock wave, and the following situations may occur:

[0131] like Fig.11 As shown in FIG. 1 , the horizontal impact force generated by the huge earthquake shock wave causes the slider 5 to slide in the sliding space, and the slider 5 has a large relative position change relative to the lower support plate 4 and the upper support plate 2. At this time, due to the large horizontal impact force, the slider 5 has a large acceleration, as shown in FIG. Fig.11 The direction indicated by the thick arrow is toward the edge of the upper spherical slideway 21 and the lower spherical slideway 41 (such as Fig.11 Since the acceleration (and / or movement speed) of the slider 5 is relatively large, and the space at the edge of the upper spherical slideway 21 and the lower spherical slideway 41 (i.e., the narrow edge of the sliding space) is difficult to accommodate the slider 5, the slider 5 moves to the position shown in the dashed box. Fig.11The corresponding collision will damage the building seismic isolation bearing, especially the materials of the upper spherical slideway 21, the lower spherical slideway 41, the upper sliding panel 52 and the lower sliding panel 53 will be worn to a greater extent or even cracked, and the damage to the building seismic isolation bearing will seriously endanger the safety of the upper building structure.

[0132] In order to avoid damaging the building isolation bearing, the third voltage is applied to each of the upper electromagnet 11 and the lower electromagnet 31 in this embodiment. After the upper electromagnet 11 and the lower electromagnet 31 are powered on, magnetic flux lines are generated; the steel plate 51 acts as a conductor to cut the magnetic flux lines and generate damping, so that the movement speed (and / or acceleration) of the slider 5 is slowed down, or the slider 5 is moved in the opposite direction to prevent the slider 5 from violently colliding with the Fig.11 At the position of the middle dotted frame, the movement of the upper support plate 2 relative to the lower support plate 4 is reduced to protect the building isolation support so that it can maintain a normal working state to reduce the damage to the building structure caused by the earthquake shock wave.

[0133] Among them, the voltage range of the third voltage is 110 volts to 380 volts, and the specific voltage value of the third voltage is determined by technical personnel in this field according to specific usage scenarios and experience.

[0134] In one embodiment, the generated damping causes the slider 5 to move in the opposite direction, such as Fig.11 As shown by the thin arrow in the middle, the damping in the corresponding direction is reduced and the slider 5 moves toward Fig.11 The acceleration (and / or, the speed) of the movement at the position of the dotted line frame is large enough, and the upper electromagnet 11 and the lower electromagnet 31 generate a strong electromagnetic field. Therefore, the damping generated by the steel plate 51 in the slider 5 cutting the magnetic flux lines can prevent the slider 5 from sliding and colliding with the earthquake shock wave, so that the slider 5 moves as shown in the following figure. Fig.11 Move in the direction of the thin arrow toward the center of the sliding space to avoid collision with the narrow edge of the sliding space.
