Referring to fig. 1 and 5, in the present embodiment, the horizontal seismic isolation bearing 2 includes a third connecting plate 2a, a fourth connecting plate 2e and a second seismic isolation structure, the fourth connecting plate and the third connecting plate are disposed at an interval, and the fourth connecting plate may be connected to the first connecting plate, or the third connecting plate and the second connecting plate may be connected. Specifically, if horizontal isolation bearing is located vertical isolation bearing below, then this third connecting plate is connected with the second connecting plate, and at this moment, the fourth connecting plate is located third connecting plate below, and the third connecting plate is located second connecting plate below. If horizontal isolation bearing is located vertical isolation bearing top, then the fourth connecting plate is connected with first connecting plate, and at this moment, this fourth connecting plate still is located this third connecting plate below, and the fourth connecting plate is located first connecting plate top. In this embodiment, it is preferable to explain that the horizontal seismic isolation support is located below the vertical seismic isolation support, that is, the fourth connecting plate is located below the third connecting plate, and the third connecting plate is connected to the second connecting plate and located below the second connecting plate.
Further, in order to facilitate connection of the horizontal isolation support 2 and the vertical isolation support 1 and adjustment of the connection position of the horizontal isolation support 2 relative to the vertical isolation support 1, the third connecting plate and the second connecting plate can be connected through screws and bolts. Also, the first connecting plate 1a, the second connecting plate 1b, the third connecting plate 2a, and the fourth connecting plate 2e may be square plates, circular plates, or U-shaped plates, etc., and the thicknesses of the four plates may be equal or different. Preferably, the first connecting plate, the second connecting plate, the third connecting plate and the fourth connecting plate are all circular plates, and the thicknesses of the four plates are equal, but the diameters of the four plates may be equal or different. More preferably, the diameters of the second connecting plate, the third connecting plate and the fourth connecting plate are equal and larger than the diameter of the first connecting plate, so that the second seismic isolation structure can be conveniently arranged.
Further, the second seismic isolation structure comprises a second seismic isolation main body 2b and a plurality of tensile components 2c, the tensile components 2c are arranged at intervals, and the second seismic isolation main body 2b is located between two adjacent tensile components 2 c. Specifically, the two tensile assemblies 2c may be symmetrically disposed with respect to the center of the third connecting plate 2a, and the second seismic isolation body 2b is located between the two second tensile assemblies 2c and has a distance to the second tensile assemblies 2 c.
In this embodiment, the second seismic isolation body 2b is a rubber-layer seismic isolation body, and includes a plurality of rubber layers 213, reinforcing plates 212, and two sealing plates 210 and 211 disposed up and down, wherein the two sealing plates 210 and 211 are respectively and fixedly connected to the third connecting plate 2a and the fourth connecting plate 2e, the plurality of reinforcing plates 212 are disposed at intervals, and the rubber layer 213 is disposed between two adjacent reinforcing plates 212. Preferably, the reinforcing plate 212 may be a reinforcing steel plate, and the rubber layer 213 may be a natural rubber layer or a high damping rubber layer, etc.
Further, the second seismic isolation body 2b is approximately arranged at the middle position of the third connecting plate 2a, and the projection position of the second seismic isolation body 2b on the second connecting plate 1b approximately coincides with the projection position of the first seismic isolation body 1c on the second connecting plate 1 b. When the first seismic isolation body 1c is a rubber seismic isolation body, the thickness of the single-layer rubber layer of the first seismic isolation body 1c is 2-5 times that of the single-layer rubber layer of the second seismic isolation body 2 b. That is, the thickness of the single-layer rubber layer of the first seismic isolation body 1c is larger than that of the second seismic isolation body 2b, because the thick rubber layer adopted by the first seismic isolation body increases the vertical deformable displacement of the first seismic isolation body in order to reduce the vertical rigidity of the first seismic isolation body, and the effect of isolating vertical earthquakes or vibration is achieved. Meanwhile, the horizontal instability of the first shock insulation main body adopting the thick rubber layer can be limited by adding the anti-pulling sleeve.
Preferably, the number of layers of the rubber layers 213 of the second seismic isolation body 2b is greater than the number of layers of the rubber layers 13 of the first seismic isolation body 1c, that is, the overall thickness of the second seismic isolation body 2b is greater than the overall thickness of the first seismic isolation body 1c, so that the second seismic isolation body 2b can also be vertically deformed in the vertical direction.
Referring to fig. 1, 5 and 6, in the present embodiment, the tensile member 2c includes an upper rotating member 20 and a lower rotating member 21. The upper rotating member 20 is rotatably connected to the third connecting plate 2a, the lower rotating member 21 is located below the upper rotating member 20 and spaced apart from the upper rotating member 20, and the lower rotating member 21 is rotatably connected to the fourth connecting plate 2 e. Specifically, the lower rotating member 21 and the upper rotating member 20 are arranged in the vertical direction, and the rotation axis of the lower rotating member 21 and the rotation axis of the upper rotating member 20 are on the same vertical line. More specifically, the upper rotating member 20 and the lower rotating member 21 may be bearings, rotating shafts, or the like.
Further, a first fixing portion 201 is disposed on the lower end surface of the third connecting plate 2a extending downward, a second fixing portion 202 is disposed on the upper end surface of the fourth connecting plate 2e extending upward, the upper rotating member 20 is rotatably connected to the first fixing portion 201, and the lower rotating member 21 is rotatably connected to the second fixing portion 202. Specifically, the first fixing portion 201 and the second fixing portion 202 are both bumps, and the upper rotating member 20 and the lower rotating member 21 are both bearings, and the bearings are sleeved on the bumps to realize rotation relative to the bumps.
Further, the first fixing portion 201 includes a first rotation plane 201a, the second fixing portion 202 includes a second rotation plane 202a, the second rotation plane 202a is parallel to the first rotation plane 201a, the upper rotation member 20 can rotate in the first rotation plane 201a, and the lower rotation member 21 can rotate in the second rotation plane 202 a.
Further, the tensile assembly 2c further includes an intermediate connecting shaft 22 and a connecting member 23, the intermediate connecting shaft 22 is located between the upper rotating member 20 and the lower rotating member 21, the upper end and the lower end of the intermediate connecting shaft 22 are respectively fixedly connected to the upper rotating member 20 and the lower rotating member 21, and the lower end of the intermediate connecting shaft 22 is provided with a third sliding portion 22 a. The connecting member 23 is disposed above the lower rotating member 21, a sliding groove 23a is formed in the connecting member 23, the extending direction of which is perpendicular to the extending direction of the intermediate connecting shaft 22, and the third sliding portion 22a is slidably disposed in the sliding groove 23 a.
Specifically, the intermediate connecting shaft 22 is a vertical shaft, and the upper and lower ends of the intermediate connecting shaft 22 can be fixedly connected to the upper rotating member 20 and the lower rotating member 21 by screws and bolts, so that when the upper rotating member 20 and the lower rotating member 21 rotate, the intermediate connecting shaft 22 can also be driven by the upper rotating member 20 and the lower rotating member 21 to move, and thus the third sliding portion 22a can slide in the sliding groove 23 a.
More specifically, the third sliding portion 22a may be a cylindrical pin, a projection, or a rotating shaft, etc. provided at the lower end of the intermediate connecting shaft 22. The connecting member 23 may be a bar-shaped structure, and the length direction thereof is a horizontal direction perpendicular to the height extending direction of the intermediate connecting shaft 22, that is, the connecting member 23 is disposed along the horizontal direction, and the intermediate connecting shaft 22 is disposed along the vertical direction. Therefore, the sliding groove 23a is a horizontal bar-shaped groove, and both ends of the sliding groove 23a in the length direction have a certain distance to both end portions of the connecting member 23, that is, the sliding groove 23a is a groove with both ends closed, and both ends of the sliding groove do not penetrate through both ends of the connecting member 23.
Further, the sliding slot 23a includes two ends in the length direction, before an earthquake occurs, the third sliding portion 22a is located at the center of the sliding slot 23a or close to the center of the sliding slot, and when an earthquake occurs, the upper rotating member 20 and the lower rotating member 21 respectively rotate under the action of the earthquake, so that the middle connecting shaft 22 rotates to drive the third sliding portion 22a to slide in the sliding slot 23 a. The sliding direction of the third sliding portion 22a in the sliding groove 23a may be from the middle of the sliding groove 23a to both ends, so as to dissipate earthquake action energy in the horizontal direction and prevent the building structure from being damaged.
Furthermore, when an earthquake occurs, if a vertical action occurs, because the upper end and the lower end of the intermediate connecting shaft 22 are respectively and fixedly connected to the upper rotating part 20 and the lower rotating part 21, even under the vertical action of the earthquake, the two ends of the intermediate connecting shaft 22 can still be tightly connected with the upper rotating part 20 and the lower rotating part 21, so that the tensile action is achieved, and the situation that the tensile stress is too large due to the vertical earthquake or the vibration action of the horizontal vibration isolation support 2 is prevented.
In this embodiment, since the three-dimensional seismic isolation device of this embodiment can be applied to a seismic isolation layer, the extended length of the sliding groove 23a is greater than or equal to 2 times of the maximum allowable displacement of the seismic isolation layer, so that when an earthquake occurs, the two ends of the sliding groove 23a in the extended length direction can play a role in limiting, and the third sliding portion 22a is prevented from sliding away from the sliding groove 23a, so that the horizontal seismic isolation support 2 is prevented from being deformed too much.
Specifically, as can be seen from the above, taking the rubber body of which the second seismic isolation body is circular as an example, the maximum allowable displacement of the seismic isolation layer is the larger of the diameter of the second seismic isolation body which is 0.55 times the diameter of the second seismic isolation body and the total thickness of the inner rubber layer of the second seismic isolation body which is 3 times the total thickness of the inner rubber layer of the second seismic isolation body.
Further, since the second seismic-isolation body 2b is located between the adjacent two tension resistant members 2c, the connecting member 23 is horizontally disposed, and therefore, the distance L1 from the end of the connecting member 23 near the one end of the second seismic-isolation body 2b to the edge of the second seismic-isolation body 2b toward the connecting member 23 is greater than or equal to the larger of the total thickness of the rubber layers in the second seismic-isolation body 2b and 1/3 times the total thickness S of the second seismic-isolation body 2b, so as to ensure that the displacement in the horizontal direction when the second seismic-isolation body 2b is subjected to an earthquake can not be affected. Wherein, the total thickness S of the second vibration isolation body 2b is the sum of the thicknesses of the plurality of rubber layers, the reinforcing plate and the two sealing plates.
Referring to fig. 1 and 7 again, in the present embodiment, the tensile track of the tensile member 2c along the vertical direction is not overlapped with the tensile track of the vertical seismic isolation member 1d along the vertical direction. Specifically, taking the example that the second connecting plate 1b and the third connecting plate 2a are circular plates and the third connecting plate 2a and the second connecting plate 1b are completely overlapped, the second connecting plate 1b includes a central region 105 at the center thereof and an edge region 106 extending outward from the central region 105, the projections of the vertical seismic isolation elements 1d on the second connecting plate 1b are located in the central region 105 of the second connecting plate 1b, and the projections of the tensile elements 2c on the second connecting plate 1b are located in the edge region 106 of the second connecting plate 1 b. That is, if the second link plate 1b is a circular plate and the first link plate 1a and the fourth link plate 2e are also circular plates, the diameter of the second link plate 1b is larger than the diameter of the first link plate 1 a. As can be seen from the above, the first connecting plate 1a, the second connecting plate 1b, the third connecting plate 2a and the fourth connecting plate 2e can be fixedly connected by bolts and screws, so that the first connecting plate 1a, the second connecting plate 1b, the third connecting plate 2a and the fourth connecting plate 2e are all provided with screw holes, and the second connecting plate 1b is divided into a central region 105 and a projected region by the screw holes, that is, the projections of the plurality of vertical seismic isolation assemblies 1d on the second connecting plate 1b are located in the central region 105 inward of the screw holes, and the projections of the plurality of tensile assemblies 2c on the second connecting plate 1b are located in the edge region 106 outward of the screw holes.
That is to say, taking the center of the second connecting plate 1b as the center of circle, the diameter of the circle formed by the enclosure of the projections of the plurality of vertical seismic isolation assemblies 1d on the second connecting plate 1b is smaller than the diameter of the circle formed by the enclosure of the projections of the plurality of tensile assemblies 2c on the second connecting plate 1 b.
The vibration isolation process of the three-dimensional vibration isolation device of the embodiment under the action of earthquake is briefly described as follows:
when no earthquake occurs, the first shock insulation main body 1c is connected between the first connecting plate 1a and the second connecting plate 1b in a natural pressure bearing state, the top of the second anti-pulling sleeve 15 and the bottom of the first anti-pulling sleeve 14 have a certain distance due to pressure bearing, and at the moment, the first elastic resetting piece 16 positioned in the second anti-pulling sleeve is in a natural pressure bearing state.
Similarly, the second seismic isolation body 2b is naturally connected between the third connecting plate 2a and the fourth connecting plate 2e, the third sliding portion 22a is located at the middle position of the sliding groove 23a, and the upper rotating member 20 and the lower rotating member 21 do not rotate.
When an earthquake occurs, the first seismic isolation main body 1c is pressed or pulled by the vertical action of the earthquake, and meanwhile, the first elastic resetting piece 16 is also pressed or pulled by the vertical action of the earthquake to drive the second uplift sleeve 15 to start to slide in the first uplift sleeve 14, however, due to the action of the first limiting step 14a and the second sliding portion 15a, the top of the second uplift sleeve 15 is always positioned in the first uplift sleeve 14 in a sliding manner, cannot be separated from the first uplift sleeve 14, and cannot slide in the first uplift sleeve 14 along the horizontal direction, so that the second uplift sleeve 15, the first uplift sleeve 14 and the first seismic isolation main body 1c can dissipate the earthquake action to play a seismic isolation role. After the earthquake action is finished, the first seismic isolation body 1c can be restored to the original state due to the material characteristics thereof, and meanwhile, the first elastic restoring member 16 is also restored to the original state due to the material characteristics thereof, so that the acting force for restoring the second anti-pulling sleeve 15 to the original position thereof is provided.
Similarly, when the earthquake acts on, the upper rotating part 20 and the lower rotating part 21 respectively rotate for 360 degrees on the first rotating plane 201a and the second rotating plane 202a under the action of the earthquake, so that the middle connecting shaft 22 connected with the upper rotating part and the lower rotating part moves, the third sliding part 22a arranged on the middle connecting shaft 22 horizontally slides in the sliding groove 23a, and the earthquake energy can be dissipated to achieve the shock insulation effect. After the earthquake action is finished, the third sliding part 22a on the intermediate connecting shaft 22 can be restored to its initial position under the action of the second seismic isolation body 2 b.
Further, as can be seen from the above, in the above tensile member 2c, the upper rotating member and the lower rotating member can freely rotate within 360 ° in the plane, so the motion trajectory thereof will be briefly described in the following two cases:
in the first case: when the earthquake acts in the longitudinal direction of the chute and in the longitudinal direction X of the chute, the initial position W1 and the post-movement position W2 of the third slide portion 22a are as shown in fig. 8. Wherein the variable maximum displacement of the third sliding portion 22a in the X direction under the action of an earthquake is L, and at the same time, L is the maximum allowable deformation of the seismic isolation layer (as can be seen from the above, the maximum allowable displacement of the seismic isolation layer is determined by the larger value of the two of 0.55 times the diameter of the second seismic isolation body and 3 times the total thickness of the inner rubber layer of the second seismic isolation body).
In the second case: when the earthquake acts in any direction, the second seismic isolation bearing deforms in any direction, at this time, the sliding groove 23a rotates to the corresponding direction under the rotation action of the upper rotating member and the lower rotating member under the action of the third sliding portion 22a, the third sliding portion slides in the sliding groove at the same time, the initial position W3 and the position W4 after movement of the third sliding portion 22a are as shown in fig. 9, the variable maximum displacement of the third sliding portion in any direction is L, and L is the maximum allowable deformation of the seismic isolation layer.
From the above analysis, it can be seen that the third sliding portion slides in the sliding groove, and due to the 360 ° free rotation of the upper rotating member and the lower rotating member, the third sliding portion can reach an arbitrary position in a circle having the initial position W3 as the center and the radius L as the radius on the X-Y plane. Therefore, the boundary locus of the allowable deformation of the third sliding portion is a circle having the initial position W3 as the center and the allowable value L of the deformation of the third sliding portion in the one-way movement in the chute as the radius.
The embodiment of the utility model provides a three-dimensional shock isolation device realizes the shock insulation function on three-dimensional shock isolation device's the vertical direction and the shock insulation function on the horizontal direction respectively through setting up vertical shock insulation subassembly 1d, first shock insulation main part 1c, second shock insulation main part 2b and tensile subassembly 2c for three-dimensional shock isolation device also can have good shock insulation effect under the equidirectional seismic action, prevents that building structure from receiving earthquake and destroying.
In addition, the tensile assembly 2c adopts the way that the upper rotating part 20, the lower rotating part 21, the middle connecting shaft 22 and the connecting part 23 are mutually matched, and the sliding acting force of the third sliding part 22a on the middle connecting shaft 22 relative to the sliding groove 23a of the connecting part 23 is provided by utilizing the rotation of the upper rotating part 20 and the lower rotating part 21 under the action of an earthquake respectively, so that the horizontal shock-insulation support 2 can be correspondingly horizontally deformed, and a good shock-insulation effect is achieved. In addition, the upper and lower rotating members 20 and 21 limit the position of the intermediate connecting shaft 22 in the vertical direction, thereby exerting a tensile action.
Example two
Fig. 7 to 9 are schematic structural views of a three-dimensional seismic isolation apparatus according to a second embodiment of the present invention. The three-dimensional seismic isolation device of the second embodiment is different from the three-dimensional seismic isolation device of the first embodiment in that:
the first seismic isolation body 1c is a solid damping particle. Specifically, in order to facilitate the arrangement of the solid damping particles and ensure that the solid damping particles can collide with each other under the action of an earthquake, an enclosure plate 17 enclosing a cavity 170 is arranged between two adjacent vertical seismic isolation assemblies 1d, the enclosure plate 17 is vertically arranged, the bottom end of the enclosure plate is fixedly connected with a second connecting plate 1b, the top end of the enclosure plate is fixedly connected with a first connecting plate 1a through a flexible part 18, and the solid damping particles can be filled in the cavity 170. More specifically, the containment plate 17 is a steel plate, and the containment plate 17 may be a one-piece circular plate, which is enclosed between two vertical seismic isolation assemblies 1d, and the cavity 170 formed is a circular cavity. Alternatively, the containment plate 17 may be a plurality of square plates enclosed between two vertical seismic isolation assemblies 1d, and the formed cavity 170 may be a square cavity.
Further, taking the enclosure plate 17 as a circular steel plate as an example, the bottom end of the enclosure plate 17 may be connected to the second connecting plate 1b by bolts, screws, welding or glue. The top end of the containment sheet 17 may be fixedly connected to the first connecting plate 1a by a flexible member 18. The flexible member 18 may be a rubber plate, a silicone plate, a metal elastic sheet, or the like, and the flexible member 18 may be connected to the first connecting plate 1a by screws, bolts, welding, or glue bonding, so that the cavity 170 forms a closed cavity, that is, the first connecting plate 1a and the second connecting plate 1b form the top and the bottom of the cavity 170, respectively, so that when the cavity 170 is filled with the solid damping particles, the solid damping particles are prevented from being separated from the cavity 170.
Further, the containment plate 17 may have the same height as the second pullout sleeve 15, and the flexible member 18 may have the same height as the first pullout sleeve 14.
In the present embodiment, the filling amount of the solid damping particles in the cavity 170 may be 10% to 70% of the volume of the cavity 170, for example, the filling amount of the solid damping particles may be 10%, 20%, 30%, 40%, 50%, 60%, 70%, etc. Thus, when an earthquake occurs, the cavity 170 has enough space to enable the solid damping particles to move irregularly and collide in the cavity 170 (the collision can be between the solid damping particles and the containment plate 17, between the solid damping particles and the first connecting plate 1a and between the solid damping particles and the second connecting plate 1 b), so that the damping of the vertical seismic isolation support 1 can be increased due to the irregular movement and collision of the solid damping particles, partial seismic energy is dissipated, and the influence of the earthquake on the upper structure of a seismic isolation layer is reduced.
Preferably, the solid damping particles may be rubber particles or metal particles having a certain mass, and the particle size of the solid damping particles may be different, for example, the particle size of some solid damping particles is the same but different from that of another part of solid damping particles, or the particle size of each solid damping particle is different, so that each solid damping particle can irregularly move and collide under the action of an earthquake when the earthquake occurs.
Further, in order to avoid horizontal deformation of the vertical seismic isolation support 1 under the action of an earthquake, the first seismic isolation structure further comprises a plurality of horizontal seismic isolation assemblies 1e, and the plurality of horizontal seismic isolation assemblies 1e are located in the cavity 170. Namely, the projections of the plurality of horizontal seismic isolation assemblies 1e on the second connecting plate 1b are positioned in a circle surrounded by the projections of the plurality of vertical seismic isolation assemblies 1d on the second connecting plate 1 b. The horizontal seismic isolation assemblies 1e may be two, three or more, and the like, and two adjacent horizontal seismic isolation assemblies 1e are disposed at intervals.
Specifically, the horizontal seismic isolation assembly 1e includes an upper sleeve 19a and a lower sleeve 19b, and the top of the upper sleeve 19a is fixed to the first connection plate 1 a. The bottom of the lower sleeve 19b is fixed to the second connecting plate 1b, the inside of the lower sleeve 19b communicates with the inside of the upper sleeve 19a, and the lower sleeve is slidably connected to the upper sleeve. More specifically, the upper sleeve 19a is a hollow sleeve with an upper opening and a lower opening, the top of the upper sleeve 19a can be fixedly connected to the first connection plate 1a by means of bolts or screws, and the height of the upper sleeve 19a is equal to the height of the first anti-pulling sleeve 14, but the width of the upper sleeve 19a is smaller than the width of the first anti-pulling sleeve 14, so that the occupied space of the upper sleeve 19a on the first connection plate 1a can be smaller than the occupied space of the first anti-pulling sleeve 14 on the first connection plate 1 a. Similarly, the lower sleeve 19b is also a hollow sleeve with an upper opening and a lower opening, the bottom of the lower sleeve 19b can be fixed to the second connecting plate 1b by bolts or screws, the height of the lower sleeve 19b is equal to the height of the second anti-pulling sleeve 15, but the width of the lower sleeve 19b is smaller than or equal to the width of the second anti-pulling sleeve 15.
Further, in order to facilitate the sliding connection between the lower sleeve and the upper sleeve, the inner wall surface of the upper sleeve 19a is provided with a first connecting portion (not shown), the outer wall surface of the lower sleeve 19b is provided with a second connecting portion (not shown), the first connecting portion is a clamping groove formed in the inner wall surface of the upper sleeve 19a in a sliding manner, the second connecting portion is a projection formed in the outer wall surface of the lower sleeve 19b in a sliding manner, and the projection is slidably connected in the clamping groove, so that the top of the lower sleeve 19b can slide in the upper sleeve 19 a. When no earthquake occurs, the second connecting portion is slidably engaged with the first connecting portion at a position close to the bottom of the upper sleeve 19a, and the lower sleeve 19b does not slide relative to the upper sleeve 19 a. When the earthquake takes place, under the earthquake effect, the second connecting portion upwards slides along first connecting portion, nevertheless at whole slip in-process, because the card of this second connecting portion and first connecting portion establishes the effect, this second connecting portion can't break away from this first connecting portion, and because the second connecting portion is located this first connecting portion all the time, consequently, lower part sleeve 19b can only take place the ascending motion of vertical direction, and then can't take place owing to the effect of blockking of upper portion sleeve 19a on the horizontal direction, thereby effectively prevent the deformation that this vertical shock insulation support 1 takes place on the horizontal direction. Preferably, the first connecting portions provided on the upper sleeve 19a may be four and arranged in a circle along the center of the upper sleeve 19a, and the second connecting portions provided on the lower sleeve 19b may be four and arranged in a circle along the center of the lower sleeve 19 b.
In this embodiment, the horizontal seismic isolation assembly 1e further includes a second elastic restoring member 19c, the second elastic restoring member 19c is located in the upper sleeve 19a and the lower sleeve 19b, the top of the second elastic restoring member 19c is fixedly disposed on the first connecting plate 1a, and the bottom of the second elastic restoring member 19c is fixedly disposed on the second connecting plate 1 b. In particular, the second elastic return element 19c, which may also be a spring, may be used to be compressed or pulled during the action of the earthquake, so that the lower sleeve 19b may be displaced vertically with respect to the upper sleeve 19a, while the second elastic return element 19c may also be used to provide a force to return the lower sleeve 19b to its initial position with respect to the upper sleeve 19a at the end of the earthquake.
It is understood that, in this embodiment, the structure of the horizontal seismic isolation mount 2 is the same as that of the horizontal seismic isolation mount 2 in the first embodiment, and the description thereof is omitted.
The embodiment two discloses three-dimensional seismic isolation device through setting up apron plate 17 vacuole formation 170, sets up the solid damping granule of a certain amount in cavity 170, sets up a plurality of horizontal shock insulation subassembly 1e simultaneously in cavity 170 to when the earthquake takes place, irregular motion and collision can take place for this solid damping granule of a certain amount, dissipation part seismic energy. Meanwhile, the horizontal shock insulation assembly 1e can be vertically deformed, but can be limited to be horizontally deformed, so that the vertical shock insulation function is realized, the deformation in the horizontal direction can be avoided, and the influence of the earthquake action on the vertical shock insulation support 1 is reduced.
EXAMPLE III
Please refer to fig. 13 to fig. 15, which are schematic structural views of a three-dimensional seismic isolation apparatus according to a third embodiment of the present invention. The embodiment of the utility model provides a three-dimensional shock isolation device that discloses three lies in with the difference of the three-dimensional shock isolation device that above-mentioned embodiment a discloses:
the embodiment of the utility model provides a third second isolation structure is still including blockking module 40, should blockking that module 40 slidable locates spout 23a, and should block module 40 and be used for contacting with third sliding part 22a and slide under third sliding part 22a pressure effect, wherein, it is perpendicular with the length direction of spout 23a to block the gliding direction of module 40 emergence. Specifically, the sliding groove 23a is an elongated groove including a first end 232 and a second end 233 opposite to each other, and an intermediate position between the first end and the second end (i.e., an initial position where the third sliding portion is located). The third sliding portion is slidable within the slide groove 23a from a middle position 231 of the slide groove 23a toward the first end portion 232 or the second end portion 233. That is, before the earthquake occurs, the third sliding portion 22a may be still located at the middle position 231 of the sliding slot 23a, and the middle position 231 is preferably the position where the center of the sliding slot 23a is located, i.e., the distance from the middle position 231 to the first end 232 is equal to the distance from the middle position 231 to the second end 233. That is, the middle position 231 of the slide groove 23a is the initial position of the third sliding portion 22a, and when the earthquake action occurs, the third sliding portion 22a can slide from the middle position 231 to the first end portion 232 or from the middle position 231 to the second end portion 233 under the earthquake action, so as to dissipate the earthquake action energy in the horizontal direction.
Further, the two blocking modules 40 may be symmetrically located at two sides of the third sliding portion 22a relative to the center of the sliding slot 23a, and when the third sliding portion 22a slides from the middle position 231 of the sliding slot 23a to the first end portion 232 or the second end portion 233 in the sliding slot 23a, the third sliding portion 22a presses the two blocking modules 40, respectively. More specifically, one of the barrier modules 40 is located between the middle position 231 to the first end 232, and the other barrier module 40 is located between the middle position 231 to the second end 233. That is, before the earthquake acts, the third sliding portion 22a may contact the two barrier modules 40, at which time the barrier modules 40 do not slide with respect to the sliding grooves 23 a. During earthquake action, the third sliding portion 22a is horizontally slid from the middle position 231 to the first end 232 or the second end 233 by the earthquake action, so that the blocking module 40 is pressed during the sliding of the third sliding portion 22a, the blocking module 40 slides relative to the sliding groove 23a, and the blocking module 40 can block the horizontal sliding of the third sliding portion 22 a. Meanwhile, the blocking module 40 can also provide a shearing force to the third sliding portion 22a during wind load, thereby playing a role in resisting wind.
Further, a first groove is formed at a position of the sliding groove 23a corresponding to the blocking module 40, and the first groove is communicated with the sliding groove 23a and extends from the sliding groove 23a to the lower rotating member 21, so that the blocking module 40 can slide in the first groove.
Further, the blocking module 40 includes a compression block 41 and a third elastic restoring member 42, the compression block 41 is slidably connected to the first groove (not shown), the compression block 41 is configured to contact the third sliding portion 22a, the third elastic restoring member 42 is located in the first groove, one end of the third elastic restoring member 42 is fixedly connected to the lower rotating portion 21, and the other end of the third elastic restoring member 42 is fixedly connected to the compression block 41. Specifically, the compression stop 41 is a hemispherical block. Before the earthquake occurs, when the third sliding portion 22a is located at the middle position 231, the compression stopper 41 is located in the slide groove 23a and contacts the third sliding portion 22 a. When an earthquake occurs, the third sliding portion 22a slides from the middle position 231 to the first end portion 232 or the second end portion 233, so that the third sliding portion 22a presses the compression stop 41 and causes the compression stop 41 to be pressed from the sliding slot 23a to retract into the first groove, and the third elastic restoring member 42 is pressed between the compression stop 41 and the lower rotating member 21. After the earthquake action is finished, the compression stop 41 can be restored to the original state and position under the action of the third elastic restoring piece 42 due to the action of the third elastic restoring piece 42, and then the compression stop 41 can be restored to be positioned in the sliding groove 23 a.
Preferably, the third elastic restoring member 42 is a compression spring. The third elastic restoring piece 42 and the compression stop 41 work together to provide a shearing resisting acting force which is larger than or equal to 650kN to the third sliding part 22a when wind load acts, and the wind resisting effect is achieved. Meanwhile, after the earthquake is finished, the compression stop block 41 can be reset under the action of the third elastic resetting piece 42, so that the wind resistance function of the compression stop block can be continuous, and the device does not need to be replaced after the earthquake.
In this embodiment, as can be seen from the above, the compression stop 41 is a hemispherical block, the third sliding portion 22a is a cylindrical pin, the compression stop 41 includes a first contact surface 41a, the third sliding portion 22a includes a second contact surface 222, the first contact surface 41a is used for contacting the second contact surface 222, and both the first contact surface 41a and the second contact surface 222 are convex arc surfaces. That is, the first contact surface 41a is an outer surface of the compression stopper 41, and the second contact surface 222 is also an outer surface of the third sliding portion 22 a. When the third slide portion 22a is located at the middle position 231 of the slide groove 23a, the second contact surface 222 just contacts the first contact surface 41 a. Preferably, the first contact surface and the second contact surface are both convex arc surfaces.

Meanwhile, when the first contact surface of the compression stopper is a convex arc surface, the pressure direction of the third sliding portion 22a on the compression stopper is a direction perpendicular to the tangent line of the first contact surface of the compression stopper, as shown by a pressure F1 applied to the stopper in fig. 15, the acting force F1 has a vertically downward acting component according to the synthesis and decomposition of the force, so that the compression spring 42 is compressed in the vertical direction, and the stopper can slide in the vertical direction;
in addition, during earthquake action, the third sliding part 22a can overcome the resistance of the compression stop block to the first sliding part, so that the third sliding part can slide in the sliding groove 23a, due to the fluctuation of the earthquake action, the third sliding part 22a can reciprocate in the sliding groove 23a, and when the first sliding part 32a slides from the second end or the first end of the sliding groove to the middle position 203, the first contact surface of the compression stop block is a convex cambered surface, so that the reciprocating motion of the first sliding part can be facilitated.
Specifically, in order to facilitate rapid sliding deformation of the third sliding portion 22a during earthquake action, the radius of the compression stopper 41 is less than or equal to one-half of the radius of the third sliding portion 22 a. More specifically, the diameter of the compression stopper 41 is matched with the opening size of the first groove, so that the compression stopper 41 can slide relative to the first groove under the action of the third sliding portion 22a and the third elastic restoring member 42.
Further, as can be seen from the above, the third elastic restoring member 42 and the compression stop 41 cooperate to provide a shear force greater than or equal to 650kN to the third sliding portion 22a under the action of wind load, so as to exert a wind resisting action, while the shear force of the compression stop 41 is mainly exerted by the shear forceThe vertical force is provided by a third elastic return element 42, i.e. a compression spring, located in the lower part thereof, so that the compression spring has a stiffness in the range K of

Wherein r is the radius of the compression stop 41, α is the angle between the connecting line of the center of the third sliding part 22a and the center of the compression stop 41 and the bottom 235 of the sliding slot 23a when the third sliding part 22a is located at the middle position 231 of the sliding slot 23a, and r is the radius of the compression stop 411Specifically, as shown in fig. 15, fig. 15 shows a schematic diagram of the stress analysis of the third sliding portion 22a and the compression stop 41 in a critical state (i.e., the third sliding portion 22a is located at the middle position 231), the compressible stop 41 is used to provide the pin with a shear force under wind load, and the key is whether the selection of the stiffness of the compression spring under the hemispherical stop is reasonable or not, the radius of the third sliding portion 22a is R, the radius of the compression stop 41 is R, the angle between the line connecting the center of the third sliding portion 22a and the center of the compression stop 41 and the bottom plane of the chute 23a in the initial position (i.e., the third sliding portion 22a is located at the middle position 231) is α, the angle between the line between the center of the third sliding portion 22a and the center of the compression stop 41 and the bottom plane of the chute 23a is α, the force and the direction of the third sliding portion 22a are analyzed as shown in fig. the stress analysis of the third sliding portion 22a is F, and the resistance of the compression stop 41 to the third sliding portion 22a is F under wind load, and the shear force of the third sliding portion 22a is1The downward pressure of the slide groove 23a on the third slide portion 22a is F2(ii) a The force analysis for the compression stop 41 is: the reaction force of the third sliding portion 22a against the compression stopper 41 is F1The upward acting force of the compression spring at the lower part of the compression stopper 41 on the compression stopper 41 is F3The reaction force of the inner side wall of the first groove to the stop block is F4。
According to the mechanical equilibrium equation, the following can be obtained:
F1cosα-F＝0； (1)
F1sinα-F3＝0； (2)
F3＝Kx； (3)
wherein K is the rigidity of the compression spring, and x is the compression amount of the compression spring.

as can be seen from FIG. 4:
Figure DEST_PATH_GDA0002557075990000203
in the case of wind resistance, the compression stop 41 must provide a shear force of 650kN or more to ensure the wind resistance of the composite seismic isolation apparatus 100. Therefore, when the third sliding portion 22a and the compression stopper 41 are in the wind-resistant critical state, the shearing force F of the wind load applied to the third sliding portion 22a is 650 kN. In a critical state, the compression spring is about to generate compression deformation; the third sliding part 22a then continues to compress the stop 41 until the stop 41 is pressed below the level of the bottom surface 205 of the run-in chute 23a and the stop 41 is compressed into the first recess, at which point the compression spring reaches its maximum compression r. Let the initial deformation of the pressure spring in the initial state be r1Since the initial deformation amount is a slight deformation amount, the third sliding portion 22a comes into contact with the compression stopper 41 in a critical state, and the compression spring can be in a pressure-receiving state. Wherein 0<1R is less than or equal to r, the compression deformation range of the pressure spring is r1≤x≤r； (5)
Substituting the formula (5) into the formula (4) can obtain the design rigidity K range of the pressure spring as follows:
Figure DEST_PATH_GDA0002557075990000204
that is to say, when the rigidity of pressure spring satisfies above-mentioned scope, adopt the utility model discloses a scheme, when the wind carries the effect, this pressure spring, compression dog 41 cooperation can provide the effort of shearing that is greater than or equal to 650kN for third sliding part 22a to make this seismic isolation device 100 have the anti-wind effect.
Referring to fig. 13 and 14 again, in order to further enable the second seismic isolation structure to have a limiting function, the second seismic isolation structure further includes two fourth elastic restoring members 51 located in the sliding groove 23a, each of the two fourth elastic restoring members 51 includes a fixed end 51a and a free end 51b, the two fixed ends 51a are respectively fixed on the first end 232 and the second end 233, and the two free ends 51b are respectively disposed toward the third sliding portion 22 a. Specifically, the fourth elastic restoring element 51 may be a tension spring, and the two fourth elastic restoring elements 51 extend in the sliding slot 23a along the length direction of the sliding slot 23a, and the centers of the two fourth elastic restoring elements 51 and the center of the third sliding portion 22a are located on the same horizontal line, so as to ensure that when the third sliding portion 22a slides from the middle position 231 to the first end portion 232 or the second end portion 233, the third sliding portion 22a can slide to contact with the free end 51b of the fourth elastic restoring element 51 and press the free end 51b, so that the fourth elastic restoring element 51 is pressed.
Furthermore, in order to ensure that the third sliding portion 22a can press the free end 51b during sliding, two fourth sliding portions 52 may be further disposed in the sliding slot 23a, and the two fourth sliding portions 52 are respectively fixed to the free ends 51b of the two fourth elastic restoring members 51. Specifically, the two fourth sliding portions 52 may be vertical pins disposed in the sliding grooves 23a, that is, the height direction of the fourth sliding portions 52 is perpendicular to the stretching or extruding direction of the fourth elastic restoring member 51.
Further, in order to make the third sliding portion 22a slide from the middle position 231 to the first end 232 or the second end 233 during the earthquake action and make the compression stopper 41 contact with the fourth sliding portion 52 to press the fourth sliding portion 52 after the compression stopper 41 is compressed until the compression stopper 41 is located in the first groove, when the third sliding portion 22a is located at the middle position 231, a gap is formed between the fourth sliding portion 52 and the third sliding portion 22a, and the gap is greater than or equal to the movement displacement of the second contact surface 222 of the third sliding portion 22a on the first contact surface 41a of the compression stopper 41 until the compression stopper 41 is located in the first groove.

As can be seen from the above, when the third sliding portion 22a is a cylindrical pin, the third distance L3 is the radius of the third sliding portion 22 a.
That is, when the length L0 of the sliding groove 23a satisfies the above condition, the sliding groove 23a and the fourth elastic restoring member 51 of the three-vibration isolator of the present invention can restrict excessive deformation of the third sliding portion 22a during an earthquake, thereby performing a limiting function.
