Description

Technical Field

[0001] The present invention relates to the technical field of seismic isolation bearings, and in particular to a seismic isolation bearing for construction engineering. Background Art

[0002] In the existing definitions, seismic isolation bearings refer to the supporting devices set up in the structure to meet the seismic isolation requirements. It is to add a seismic isolation layer between the superstructure and the foundation, install seismic isolation bearings, and play a soft connection with the ground. Through this technology, about 80% of the energy of the earthquake can be offset. With the development of society and people's research on seismic isolation bearings, the existing seismic isolation bearings include but are not limited to the following types: First: Lead rubber bearing: absorbs and dissipates seismic energy through shear deformation of lead core and rubber.

[0003] Second: Hydraulic viscous damper: The flow of liquid or semi-solid viscous material in the cylinder generates damping force to dissipate and absorb seismic energy.

[0004] Third: Friction damping bearing: Two spherical surfaces with different radii are used to form two sliding friction pairs with the matching position to ensure the normal rotation and sliding function of the bearing. When the horizontal force of the earthquake exceeds the threshold, the friction pairs of the bearing overcome the friction force to produce relative sliding. The large-radius spherical friction pair can produce a large horizontal relative displacement, that is, the horizontal stiffness is small, thereby converting the kinetic energy generated by the earthquake into potential energy. After breaking through the threshold, the small horizontal stiffness plays a "seismic isolation" role. At the same time, due to the existence of friction resistance, it plays a "damping" role and consumes part of the earthquake energy.

[0005] Fourth: Tension support: Rely on the convex and concave connection between the upper support plate and the lower support plate to resist tension.

[0006] The above-mentioned types of seismic isolation bearings are mainly composed of three parts: upper components, seismic isolation components and lower components. The volume and specifications of the seismic isolation bearings will be determined according to actual usage requirements, while the volume and specifications of existing seismic isolation bearings are fixed, which results in poor versatility of seismic isolation bearings and affects usage requirements.

[0028] As an implementation of this solution, the limit length of the elastic rope 47 is smaller than the sliding distance of the auxiliary block 46 in the auxiliary groove 45 .

[0029] As an implementation mode of the present scheme, the auxiliary block 46 divides the space in the auxiliary groove 45 into an upper cavity 451 and a lower cavity 452; the elastic rope 47 is located in the upper cavity 451; a capsule 453 is provided in the lower cavity 452; the capsule 453 is filled with glue; and the capsule 453 ruptures under pressure.

[0030] Secondly, the processing and assembly process of this scheme is as follows: The seismic isolation member 2 is composed of stacked rubber pads, and can also be a hydraulic damping seismic isolation element, which is selected according to the specific usage requirements. Then, the annular plate 16 is installed in the corresponding annular groove 15. In order to facilitate installation, the carrier plate 1 is divided into an upper part and a lower part and processed separately. The separated position is the position of the annular groove 15. After the annular plate 16 is installed in the annular groove 15 of the carrier plate 1, the magnet 17 is snapped into the corresponding position, and the upper half of the carrier plate 1 is covered and connected with the lower half, so as to realize the process of installing the annular plate 16 into the annular groove 15 on the carrier plate 1. Then, the symmetrically processed plug-in block 3 is removed, and the auxiliary block 46 is placed in the auxiliary groove 45. At the same time, the capsule 453 with glue is also placed in the lower cavity 452 of the auxiliary groove 45, and the elastic rope 47 is placed in the auxiliary The upper cavity 451 of the groove 45, the upper surface of the auxiliary block 46 is connected to the upper groove wall of the auxiliary groove 45 through the elastic rope 47, and then the lower half of the locking block 43 is inserted into the locking groove 42 on the plug block 3, and the lower half of the locking block 43 is welded to the auxiliary block 46, and the other half of the plug block 3 is covered, and the complete plug block 3 is inserted into the slot 13 on the carrier plate 1, and then the shifting block 4 is placed in the shifting groove 14 and connected to the upper surface of the plug block 3, and then the upper half of the locking block 43 is connected to the lower half, and the tension spring 41 is placed in the shifting groove 14, and one end of the tension spring 41 is connected to the shifting block 4, and the other end is connected to the groove wall of the shifting groove 14, and then the connecting piece 11 is assembled with the carrier plate 1, and the seismic isolation piece 2 is connected between the two annular plates 16 to complete the assembly process of the single group of seismic isolation components 12; Next, the solution will be further assembled before use, the specific steps are as follows: Workers will assemble multiple groups of seismic isolation components 12 according to the construction requirements of the site to meet the seismic isolation requirements under different conditions on site. After determining the corresponding number of seismic isolation components 12, the corresponding number of seismic isolation components 12 are first nested with each other. After multiple seismic isolation components 12 are nested with each other, since the annular plate 16 is rotatably connected in the annular groove 15, the magnet 17 in the carrier plate 1 of the inner seismic isolation component 12 and the magnet 17 in the carrier plate 1 of the outer seismic isolation component 12 attract each other. It can be understood that the end of the magnet 17 close to the inner edge of the carrier plate 1 is N-level, and the end of the magnet 17 close to the outer edge of the carrier plate 1 is S-level. In this way, when adjacent seismic isolation components 12 are nested with each other, After the sleeve, the magnet 17 on the inner seismic isolation component 12 and the magnet 17 on the outer seismic isolation component 12 are close to each other, so that the carrier plate 1 will rotate with the corresponding annular plate 16. After the magnet 17 on the inner seismic isolation component 12 and the magnet 17 on the outer seismic isolation component 12 attract each other and approach each other, the slot 13 on the carrier plate 1 in the inner seismic isolation component 12 is aligned with the slot 13 on the carrier plate 1 in the outer seismic isolation component 12, and the number of slots 13 on the same carrier plate 1 is greater than or equal to 2, so as to ensure the connection effect between the inner seismic isolation component 12 and the outer seismic isolation component 12, and then the dial block 4 in the inner seismic isolation component 12 is moved. After the dial block 4 is moved The shift block 4 will slide in the shifting groove 14, and the shifting block 4 will move along the radial direction of the carrier plate 1. In the process of the shifting block 4 moving away from the center of the carrier plate 1, the corresponding tension spring 41 will be overcome. The setting of the tension spring 41 makes the initial insertion block 3 shrink into the slot 13 to avoid interference caused by multiple seismic isolation components 12 nesting with each other. As the shifting block 4 is moved, the shifting block 4 will drive the insertion block 3 to slide in the corresponding slot 13. The insertion block 3 will slide along the slot 13 along the radial direction of the carrier plate 1. The insertion block 3 in the inner seismic isolation component 12 can be inserted into the corresponding slot 13 in the outer seismic isolation component 12. The insertion block 3 in the inner seismic isolation component 12 can squeeze the insertion block 3 in the slot 13 in the outer seismic isolation component 12 Go, thus completing the connection between the inner seismic isolation component 12 and the outer seismic isolation component 12. Since all the slots 13 in the multiple seismic isolation components 12 are aligned, after the plug block 3 in the innermost seismic isolation component 12 moves away from the center of the carrier plate 1, the carrier plates 1 in all the seismic isolation components 12 can be connected. In addition, since the friction force of the plug block 3 after sliding in the slot 13 is greater than the tension of the tension spring 41, the plug block 3 will not return under the pulling of the tension spring 41, thereby ensuring the connection effect of the adjacent seismic isolation components 12. After the upper and lower carrier plates 1 in the seismic isolation component 12 are connected, the assembled seismic isolation component 12 is put into use. Furthermore, the process of using this solution is as follows: After the connector 11 in the seismic isolation component 12 is inserted into the corresponding installation position, the concrete component will contact the support plate 1 of the seismic isolation component 12. The support plate 1 bears the pressure in the vertical direction. When the concrete component contacts the end surface of the support plate 1, it will squeeze the locking block 43. After being compressed, the locking block 43 will slide along the locking groove 42. The locking block 43 will move close to the seismic isolation component 2. The locking block 43 will drive the auxiliary block 46 to slide along the auxiliary groove 45. The auxiliary block 46 will pull the elastic rope 47. In the initial state, the elastic rope 47 pulls the auxiliary block 46 to be at the upper limit in the auxiliary groove 45. The locking block 43 is in the upper position before being activated in the locking groove 42, so that the movement of the plug block 3 will not be locked by the first tooth 44 on the locking block 43 and the second tooth 18 on the slot 13, so as to ensure the smoothness of the plug block 3 in the process of assembling the seismic isolation component 12. As the locking block 43 is activated, the locking block 43 will drive the auxiliary block 46 to slide along the auxiliary groove 45, and the auxiliary block 46 will pull the elastic rope 47, so that the elastic rope 47 is broken, and the auxiliary block 46 will squeeze the capsule 453 in the lower cavity 452, and the capsule 453 After being squeezed, it will rupture, and the ruptured capsule 453 will cause the glue to overflow, and the glue will flow out along the gap between the locking block 43 and the locking groove 42, so that the glue will eventually overflow to the contact position between the first tooth 44 and the second tooth 18. After the locking block 43 approaches the seismic isolation component 2 along the locking groove 42, the first tooth 44 will contact the second tooth 18, so that the plug-in block 3 is locked in the corresponding slot 13, and with the glue, the plug-in block 3 cannot move radially along the carrier plate 1 in the slot 13, so that the adjacent seismic isolation components 12 are connected; in addition, the elastic force in the upper cavity 451 After the rope 47 slides along the auxiliary groove 45 with the auxiliary block 46, the elastic rope 47 will be broken, so that the elastic rope 47 cannot pull the auxiliary block 46 to return to its original position after the auxiliary block 46 slides, and the auxiliary block 46 will move with the movement of the locking block 43. Under the setting of the elastic rope 47, the locking block 43 is located in the locking groove 42 away from the seismic isolation component 2, so that the plug block 3 will not be affected by the engagement of the first tooth 44 and the second tooth 18; in the process of generating vibrations such as earthquakes, the seismic isolation component 12 can twist to unload the force, and can also reduce shock in the up and down and horizontal directions.

[0031] Finally, the advantages of this solution compared to the existing technology are as follows: 1. In this solution, multiple seismic isolation components 12 are nested and connected with each other, so that the specifications of the seismic isolation bearing can be assembled according to the actual use requirements on site, thereby forming seismic isolation bearings of different specifications. Compared with the existing seismic isolation bearings of a single specification, this solution has a wider scope of application and stronger practicality; 2. In this solution, the locking block 43 drives the first teeth 44 to engage with the second teeth 18 in the slot 13, thereby locking the plug block 3, so that the plug block 3 is locked after being inserted into the slot 13 in the outer seismic isolation component 12, so that the connection between the inner and outer seismic isolation components 12 is more stable, thereby improving the stability of the seismic isolation support; 3. In this solution, the slots 13 are inserted through the inner and outer sides of the carrier plate 1, so that during the mutual assembly of multiple seismic isolation components 12, only the innermost plug block 3 needs to be moved to push the plug blocks 3 at other corresponding positions, so that the mutual assembly of multiple seismic isolation components 12 is faster and more convenient; 4. In this solution, a magnet 17 is arranged on the support plate 1, so that the support plate 1 in the inner seismic isolation component 12 and the support plate 1 in the outer seismic isolation component 12 rotate relative to each other under the action of magnetic force, thereby aligning the slot 13 in the inner seismic isolation component 12 with the slot 13 in the outer seismic isolation component 12, thereby improving the convenience of connecting multiple seismic isolation components 12.
