In order to facilitate the understanding of the present solution, the basic structure of the shock absorbing assembly of the seismic isolation bearing assembly of the present application will be described in detail below with reference to FIGS. 1 to 4, and it should be noted that the components of the same name referred to herein are described. Although the reference numerals are different in different drawings and embodiments, the basic structure is basically the same. Therefore, for the structural features of the basic components that are not specifically described later, the corresponding descriptions may be directly referred to.

In a specific embodiment, the seismic isolation bearing assembly provided by the present invention comprises at least two shock absorbing assemblies, each shock absorbing assembly is sequentially disposed in a vertical direction, and the shock absorbing assembly includes a base 11 disposed on the base 11 There is a bracket 111, and an elastic member 112 is connected between the bottom of the bracket 111 and the base 11. The deformation direction of the elastic member 112 is consistent with the vertical direction, and the balance body 113 is disposed on the bracket 111 so as to be pivotally fixed. The axis extends in a horizontal direction, and the axis of the balance body 113 of the adjacent two shock absorbing assemblies is perpendicular; the base 11 is further provided with a reaction force body 114, and the axis and balance body of the reaction force body 114 on the same base 11 The axes of 113 are parallel, and when the elastic member 112 is compressed to the limit state, the top end of the balance body 113 on the same base 11 is located in the same horizontal plane as the top end of the reaction force body 114.

Through the cooperation of the reaction body 114 and the balance body 113, the force of the reaction force body 114 acting on the building is offset by the cooperation structure of the balance body 113 and the elastic member 112. When a large earthquake occurs, the ground is subjected to the seismic transverse wave. When the horizontal vibration occurs due to the influence, the reaction force body 114 is subjected to moderate force on the susceptor 11 in conjunction with the ground in response to the ground horizontal vibration, and the horizontal force generated by the seismic transverse wave is cancelled. The force is prevented from being further transmitted to the building, thereby effectively avoiding damage and collapse of the building caused by horizontal vibration, and improving the overall earthquake resistance of the building; meanwhile, the isolation bearing assembly is utilized The rigid structural member such as the reaction body 114 and the balance body 113 is used as the main functional component, and the structure thereof is stable and reliable, and the damage and failure of the component due to the high vibration strength after the use of the soft component such as the rubber bearing in the prior art does not occur. The phenomenon, thereby effectively ensuring the overall structural strength of the seismic isolation bearing assembly.

It should be specially stated that, in practical applications, through the cooperation of the above components, the building using the seismic isolation bearing assembly described in the present application can be maintained in an earthquake of ten intensity or even higher intensity. The horizontal amplitude is always close to zero, which effectively suppresses the horizontal swing or vibration of the building and significantly improves the overall seismic performance of the building.

Further, the pedestal 11 has a limiting groove 115 which is matched with the balance body 113 and the reaction force body 114 respectively, and the reference axis of the limiting groove 115 is parallel to the axis of the reaction force body 114. When the reaction force body 114 is rolled due to ground vibration, the limiting groove 115 can control the rolling displacement of the reaction force body 114 within a reasonable range, and avoid the total isolation bearing seat caused by the reaction force body 114 rolling out beyond the limit position. The resulting structure is misaligned or damaged to ensure the overall structural reliability and operational stability of the isolated bearing assembly.

It should be noted that, in principle, the above-mentioned reaction force body 114 is directly disposed on the top horizontal surface of the base 11 to achieve the best working effect, and is also the most ideal component structure adaptation state. However, considering the actual working conditions, in particular, in practical applications, the groove bottom width of the limiting groove 115 is preferably 10 cm, and the width of the side walls on both sides of the groove bottom is preferably 20 cm, and the side wall and the horizontal direction are sandwiched. The angle is 5°. Of course, the actual working condition size parameter of the limiting slot 115 is not limited to the second. In principle, as long as it can meet the actual use requirements of the seismic isolation bearing assembly.

More specifically, the base 11 is provided with a recess 116, and the recess 116 is located below the bracket 111, and the elastic member 112 is a spring which is welded and fixed to the bottom of the bracket 111 and the recess 116 respectively. The groove 116 can reliably define the working position of the elastic member 112 to avoid misalignment of the elastic member 112 during actual operation; and the spring 12 welded and fixed to the bracket 111 and the groove 116 respectively as the elastic member 112 can effectively simplify the elastic member 112. The component structure ensures the structural strength, which in turn makes the overall structure of the seismic isolation bearing assembly more simple and reliable.

Further, the balance body 113 and the reaction force body 114 are both cylindrical bodies. The cylinder has small rolling and rotating resistance, and the movement during rolling or rotating is flexible and efficient, and can effectively ensure the working needs of the seismic isolation bearing assembly. In theory, any radial section can be used for the fixed-width curve (fixed-width curve: a curve with a similar circular width); fixed width: a circle placed between two parallel lines, By making it tangent to the two parallel lines, it can be done: no matter how the circle moves, it is still in the two parallel lines, and is always tangent to the two parallel lines) as the balance body 113 and The basic structure shape of the reaction force body 114 may be, for example, a structural body capable of smoothly rolling and capable of ensuring that the supported member placed thereon does not have a vertical displacement, for example, a Lelo triangle or the like. A structure in the shape of a lodge. However, in terms of the actual component life, the balance body 113 and the reaction force body 114 are both cylindrical bodies.

It should be noted that the basic structure of the susceptor 11, the susceptor 12, and the susceptor 13 referred to in the following contents can be directly referred to the susceptor 11 described above, and will not be described later; in the following The basic structure of the bracket 111, the bracket 121, and the bracket 131 may be directly referred to the bracket 111 described above, and will not be described later; the elastic member 112, the elastic member 122, and the elastic member 132 are referred to in the following. The basic structure can be directly referred to the elastic member 112 described above, which will not be described later; the basic structure of the balance body 113, the balance body 123, and the balance body 133 referred to in the following can be directly referred to above. The balance body 113 will not be described later; the basic structures of the reaction force body 114, the reaction force body 124, and the reaction force body 134 referred to in the following contents can be directly referred to the reaction force body described above. 114, the following text will not be described again; the basic structure of the limiting slot 115, the limiting slot 125, and the limiting slot 135 involved in the following content can directly refer to the limiting slot 115 described above, which is not described later. Further description; the basic knot of the groove 116, the groove 126, and the groove 136 involved in the following content Can be directly referred to above the recess 116, hereinafter omitted.

Please continue to refer to Figures 1 to 4. In the first embodiment of the present application, the shock absorbing components are two, respectively, a lower shock absorbing assembly as shown in FIGS. 1 and 2 and an upper shock absorbing assembly as shown in FIGS. 3 and 4.

In actual assembly, the lower shock absorbing assembly is disposed opposite the upper shock absorbing assembly, the bracket 111 of the lower shock absorbing assembly is located at the middle of the base 11 of the lower shock absorbing assembly, and the bracket 111 of the lower shock absorbing assembly The reaction force bodies 114 of the two lower shock absorbing assemblies are disposed on both sides, and the reaction force bodies 114 of the two lower shock absorbing assemblies on the same side are coaxially arranged; the bracket 121 of the upper shock absorbing assembly is located thereon a side edge portion of the base 12 of the shock absorbing assembly, the upper shock absorbing assembly includes a reaction force body 124 of the upper shock absorbing assembly, and an axis of the reaction force body 124 of the upper shock absorbing assembly and the lowering The axis of the reaction body 114 of the seismic assembly is perpendicular. When a high-intensity earthquake occurs, if there are mutually perpendicular X-directions and Y-directions in the horizontal plane, the upper damper assembly and the lower damper assembly can respectively perform horizontal vibrational forces in the X-direction and the Y-direction. The vibration isolation is offset, thereby effectively preventing the vibration force extending in the horizontal direction during the earthquake from being transmitted to the building, thereby improving the seismic resistance of the building.

It should be noted that in order to meet the needs of more working conditions in practical applications, especially under extreme working conditions, the above-mentioned upper shock absorbing component and lower shock absorbing component may be respectively multiple, and in this case, it should be ensured The upper shock absorbing assembly and the lower shock absorbing assembly are sequentially spaced apart in the vertical direction; in addition, in practical applications, the axis of the balance body of the upper shock absorbing assembly and the axis of the balance body of the lower shock absorbing assembly are not necessarily completely perpendicular. The two may have a certain angle in the horizontal plane. If there are multiple upper shock absorbing components and lower shock absorbing components as described above, balance between at least one upper shock absorbing component and at least one lower shock absorbing component is ensured. Under the premise that the body axis is perpendicular, the extension direction of the balance body of other shock absorbing components is not specifically limited, and can be flexibly adjusted according to actual working conditions.

It should be specially stated that, considering the principle of equipment cost and compact structure, it is an optimal solution to use a matching structure of an upper shock absorbing component and a lower shock absorbing component whose balance body axes are perpendicular to each other. Of course, in practical applications, different shock absorbing components can be used as described above, and in principle, as long as it can meet the actual use requirements of the seismic isolation bearing assembly.

Please refer to Figure 5 and Figure 6. In the second embodiment of the present application, the shock absorbing components are specifically two, and the structures of the two shock absorbing components are as shown in FIGS. 5 and 6.

In the actual assembly, each of the shock absorbing components includes a frame 130 horizontally disposed on the base 13 , and two reaction force bodies 134 , and two reaction force bodies 134 are respectively located at two ends of the frame 130 , and the frame 130 The middle portion is provided with two balance bodies 133 arranged coaxially in the horizontal direction. The two balance bodies 133 are coaxially connected with a transmission shaft 137. The upper side of the transmission shaft 137 is disposed in parallel with the transmission shaft 137. The linkage member 138, the linkage member 138 and the transmission shaft 137 are all rotatably disposed on the frame 130, and the axis of the linkage member 138 is parallel to the axis of the transmission shaft 137. In the actual working state, the frame 130 together with the balance body 133 and the fitting member thereof are interlocked with the reaction force body 134, so that the horizontal vibration can be generated in the other components except the base 13 when the horizontal vibration occurs. Displacement, in order to achieve the effect of offsetting the horizontal direction vibration force caused by the seismic transverse wave; specifically, when a high-intensity earthquake occurs, if the horizontal plane has mutually perpendicular X-direction and Y-direction, the above-mentioned vertical direction is set. The shock absorbing component can separately isolate and cancel the horizontal vibration force transmitted along the X direction and the Y direction, thereby effectively preventing the vibration force extending in the horizontal direction during the earthquake from being transmitted to the building, thereby improving the earthquake resistance of the building.

It should be noted that, in order to meet more working conditions in practical applications, especially in the use of extreme working conditions, the above-mentioned shock absorbing assembly may be specifically multiple; in addition, in practical applications, the above two adjacent shock absorbers The axis of the balance body of the component is not necessarily completely vertical, and the angle between the two may be a certain angle in the horizontal plane. If there are a plurality of shock absorbing components as described above, at least one pair of shock absorbing components are balanced 133. Under the premise that the axis is perpendicular, the axial extension direction of the balance body 133 of the other shock absorbing components is not specifically limited, and can be flexibly adjusted according to actual working conditions.

It should be particularly noted that, considering the principle of equipment cost and compact structure, the cooperation structure of the two shock absorbing assemblies whose axes of the balance body 133 are perpendicular to each other is the best solution. Of course, in practical applications, different shock absorbing components can be used as described above, and in principle, as long as it can meet the actual use requirements of the seismic isolation bearing assembly.

On the other hand, the outer wall of the transmission shaft 137 and the outer wall of the linkage member 138 have transmission teeth, and the transmission shaft 137 and the linkage member 138 are coupled to each other by the gear teeth. The tooth meshing transmission structure can further ensure the transmission stability between the transmission shaft 137 and the linkage 138, and improve the transmission efficiency between the two, so that the overall working performance of the vibration isolation bearing assembly can be significantly improved.

It should be noted that if the transmission shaft 137 and the outer wall of the linkage member 138 are driven by the static friction force generated by the contact fit, the transmission shaft 137 and the linkage member 138 need not be provided with a transmission tooth structure to simplify the separation. The structure of the seismic support assembly reduces its manufacturing costs.

Please refer to FIG. 7. FIG. 7 is a schematic structural view of a shock absorbing assembly of the seismic isolation bearing assembly according to the third embodiment of the present invention.

In a practical application, the shock absorbing members are two, and the bottom surface of the base 21 of the lower shock absorbing assembly has a limiting slot 211 into which the base 22 of the shock absorbing assembly located above is inserted, and the limiting slot 211 is inserted. A limiting frame 212 is disposed on each of the top and bottom portions, and each of the limiting frames 212 is rotatably disposed with a limiting member 213 closely attached to the base 22 of the upper shock absorbing assembly, and each limiting frame A buffer spring 214 is connected between the 212 and the inner wall of the limiting groove 211 on the side of the limiting frame 212 in the vertical direction. Through the cooperation of the limiting slot 211 and the limiting members 213 and the limiting frame 212, the vertical range of motion of the susceptor 22 located above can be effectively limited, thereby achieving the reaction force 24 for controlling the damping component located below. The purpose of the range of movement along the extension surface of the limiting slot 25, specifically, when encountering a strong wind or a severe earthquake, as the reaction force body 24 moves along the extension surface of the limiting slot 25, due to the curved structure of the limiting slot 25, The vertical height of the reaction body 24 is also moderately increased, and the reaction force body 24 drives the base 22 of the shock absorbing assembly located above to move in the vertical direction together, when the base 22 moves in the vertical direction. To a certain extent, the corresponding buffer spring 214 is compressed or stretched to the extreme position, at which time the base 22 reaches the extreme position in the vertical direction by the cooperation of the limiting slot 211 and the buffer spring 214 and does not continue along the edge. Moving in the vertical direction, thereby correspondingly limiting the movable range of the reaction body 24 along the extension surface of the limiting slot 25 within a corresponding range, avoiding the corresponding component misalignment caused by the excessive movement of the reaction force body 24 along the limiting slot 25. Or structural failure, which is significant The ability of the seismic isolation bearing assembly and the buildings above it to resist strong wind and resistance to vertical shock and vibration; at the same time, by matching the top and bottom of the base 22 of the shock absorbing assembly located above respectively The limiting member 213 can effectively ensure the linkage control capability of each vertical direction limiting component at the limiting slot 211 to the base 22 to ensure the buffering effect and transmission efficiency of the corresponding control component, and through the bonding structure and buffering The cooperative engagement of the springs 214 prevents the base 22 from creating a rigid contact with the associated components of the limiting slots 211 or the structural stems associated with the resulting structural damage.

In addition, it should be noted that the limiting member 213 is preferably a cylindrical body to ensure the normal contact and the proper matching effect of the limiting member 213 and the base 22 .

In addition, reference may be made to FIG. 8. FIG. 8 is a schematic structural diagram of a balance body having a spherical structure according to an embodiment of the present invention.

For the above embodiments and technical solutions, the structure of the balance body and the reaction force body may also be a spherical structure as shown in FIG. 8 . Specifically, a bracket 311 having a spherical groove is disposed on the base 33 . A spherical balance body 33 is disposed in the spherical groove, and a spherical reaction force body 34 is further disposed on the base 33. The two spherical structures can also ensure the centering rotation capability of the balance body 33 and the reaction force body 34. The rotation can also be regarded as a special form of fixed-axis rotation, and the technical effect of the corresponding balance body and the reaction force body and the shock absorbing assembly is achieved by the structure. In addition, due to the particularity of the spherical structure, FIG. 8 is adopted. The component structure in the middle makes it possible to achieve the damping effect of the synergistic cooperation of the two layers or even the multiple layers of the shock absorbing components in the above. However, when an earthquake occurs, since the balance body 33 and the sphere of the reaction force body 34 are not collinear, a certain torque is generated in practical applications, and the existence of the torque may cause a rotation tendency of the building, of course, due to the corresponding torque The force arm is small, so it does not cause the building to produce too strong rotation in actual working conditions, but since the torque is objectively present, it is compared with the above-mentioned technical solution using a cylindrical structure. In other words, the spherical structure scheme is not an optimal solution, and its existence is limited to theoretically achievable. Of course, the application possibilities under extreme conditions are not excluded. Therefore, depending on the actual working conditions and the operating conditions, the technician can also The spherical component structure scheme is selected to meet the corresponding technical requirements.

In a specific embodiment, the building provided by the present invention comprises a building body and a seismic isolation bearing assembly at the bottom of the building body, and the seismic isolation bearing assembly is specifically a seismic isolation bearing as described above. Assembly. The building has good seismic performance.

In summary, the seismic isolation bearing assembly provided by the present invention, through the cooperation of the reaction force body and the balance body, utilizes the cooperation structure of the balance body and the elastic member to counteract the force acting on the building of the reaction force body when the occurrence occurs. In the case of a large earthquake, the ground is affected by the transverse wave of the earthquake and the horizontal vibration occurs. At this time, the reaction force is subjected to the horizontal vibration caused by the ground and moderately rolling on the pedestal in conjunction with the ground, which will be affected by the seismic transverse wave. The generated horizontal force is offset, and the force is prevented from being further transmitted to the building, thereby effectively avoiding damage and collapse of the building caused by horizontal vibration, and improving the overall seismic capacity of the building; The seismic isolation bearing assembly utilizes a rigid structural member such as a reaction force body and a balance body as a main functional component, and the structure thereof is stable and reliable, and the vibration strength is high after the use of a soft component such as a rubber bearing in the prior art does not occur.
