Description

Technical Field

[0001] The utility model relates to the technical field of equipment seismic isolation, in particular to a seismic isolation rubber bearing with unidirectionally adjustable horizontal force. Background Technique

[0002] A seismic isolation rubber bearing is a structure formed by overlapping the advantages of steel plates and rubber, aiming to increase the seismic resistance of building structures under the actions of horizontal and vertical earthquakes, torsion, etc. The seismic isolation rubber bearing improves the damping performance of rubber by adding various compounding agents to natural rubber. This laminated product made of rubber with damping effect is similar in structure to an ordinary rubber bearing, having better seismic isolation performance and a wider application range. At present, there are various seismic isolation rubber bearings with unidirectionally adjustable horizontal force applicable to the market, but there are still some disadvantages.

[0003] The existing seismic isolation rubber bearing is formed by fixedly connecting a rubber pad to the upper and lower plates. Once the rubber pad is damaged, it cannot be replaced. At the same time, the fixed contact area between the upper and lower plates of the bearing and the equipment is fixed and cannot be enlarged to enhance the seismic isolation effect. In addition, general bearings have problems such as high processing cost, weak controllability, and weak shear resistance. For example, the Chinese utility model patent with the authorization announcement number CN217557880U discloses a new type of friction damping seismic isolation rubber bearing, including a seismic isolation rubber bearing and a friction damping device. A through hole is opened in the center of the seismic isolation rubber bearing, and at least one friction damping device is placed inside the through hole. Sealing plates are provided at both ends of the center of the seismic isolation rubber bearing or a locking plate is provided at one end thereof: The utility model effectively combines the seismic isolation rubber bearing and the friction damping device. The friction damping device utilizes the friction force generated between the friction steel plate and the friction material when the bearing undergoes horizontal shear movement, thereby providing additional damping for the bearing. The friction material uses conventional materials, is pollution-free, and its performance is less affected by temperature. It can replace the lead-core seismic isolation rubber bearing and the high-damping rubber bearing. The friction force of this friction damping device is not affected by the seismic isolation rubber bearing, and the constant damping characteristic of the bearing can be realized: At the same time, it has a higher stiffness before yielding, and the yield force can be adjusted, the wind load resistance is improved, and it has good engineering application prospects. However, this device is formed by fixedly connecting a rubber pad to the upper and lower plates. Once the rubber pad is damaged, it cannot be replaced. At the same time, the fixed contact area between the upper and lower plates of the bearing and the equipment is fixed and cannot be enlarged to enhance the seismic isolation effect. In addition, general bearings have problems such as high processing cost, weak controllability, and weak shear resistance. Therefore, we propose a seismic isolation rubber bearing with unidirectionally adjustable horizontal force to solve the problems raised above. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:

[0031] Embodiment 1: To solve the problems existing in the prior art, this embodiment adopts the following technical solution. A seismic isolation rubber bearing with unidirectional adjustable horizontal force is provided with an upper top plate 1. The upper part of the upper top plate 1 is fixedly connected to the upper equipment by bolts. A lower bottom plate 2 is arranged below the upper top plate 1. The lower part of the lower bottom plate 2 is fixedly connected to the lower foundation embedment by bolts. Placing grooves 3 are opened inside both the upper top plate 1 and the lower bottom plate 2; A disassembly facilitating mechanism is arranged outside the rubber pad 4. Once the rubber pad 4 is damaged, it is convenient to quickly replace the rubber pad 4; A mechanism for enhancing the seismic isolation effect is arranged outside the upper top plate 1 and the lower bottom plate 2, which can increase the installation area between the upper top plate 1 and the lower bottom plate 2 and the upper equipment and the lower foundation embedment respectively, making the seismic isolation effect better; A mechanism with high bearing capacity, tensile resistance and anti-overturning is arranged inside the upper top plate 1 and the lower bottom plate 2. A vertical oblong hole is arranged inside the upper connecting plug plate 9, a round hole is arranged inside the friction plate 10, and a horizontal oblong hole is arranged inside the lower connecting plug plate 11, which effectively limits the position while ensuring displacement, and plays a certain role in tensile resistance and anti-overturning in the vertical direction; First, placing grooves 3 are opened inside both the upper top plate 1 and the lower bottom plate 2. The rubber pad 4 is placed inside the placing groove 3. A fixing plate 5 is arranged outside the rubber pad 4. When holding the handle 7 and rotating it by hand, the threaded rod 6 and the support block 8 will be threadedly connected. The threaded rod 6 will push the fixing plate 5 to closely fit with the rubber pad 4 to limit its position. If the rubber pad 4 needs to be replaced, directly unscrew the fixed threaded rod 6 and the support block 8, and the rubber pad 4 can be replaced. At the same time, upper connecting plug plates 9 are fixedly installed on the left and right sides below the upper top plate 1. Vertical oblong holes are opened inside the upper connecting plug plates 9. In addition, lower connecting plug plates 11 are symmetrically installed on the left and right above the lower bottom plate 2. Horizontal oblong holes are opened inside the lower connecting plug plates 11. Secondly, a friction plate 10 is arranged between the upper connecting plug plate 9 and the lower connecting plug plate 11. A round hole is opened inside the friction plate 10. The upper connecting plug plate 9, the friction plate 10 and the lower connecting plug plate 11 are fixedly connected by fastening bolts 12. The upper connecting plug plate 9, the friction plate 10 and the lower connecting plug plate 11 are arranged in an overlapping manner, and certain round holes are arranged inside them, that is, while ensuring displacement, it effectively limits the position, and plays a certain role in tensile resistance and anti-overturning in the vertical direction. Secondly, cylindrical shafts 13 are symmetrically installed on the left and right outside the upper top plate 1 and the lower bottom plate 2. Expansion plates 14 are rotatably connected to the outside of the cylindrical shafts 13. The expansion plates 14 and the upper top plate 1 and the lower bottom plate 2 are fixed by screws 15. That is, unscrew the fixed screws 15 and expand the expansion plates 14 outward. When the expansion is in the same horizontal direction as the upper top plate 1 and the lower bottom plate 2, the installation contact area with the equipment can be expanded, enhancing the seismic isolation effect.

[0032] In the existing seismic isolation rubber bearing with unidirectional adjustable horizontal force, the rubber pad 4 is fixedly connected to the upper and lower plates to form an integral body. Once the rubber pad 4 is damaged, it cannot be replaced. For example Figure 1, Figure 3 and Figure 6 As shown in Figure 3 and Figure 6 , the disassembly mechanism includes fixing plates 5 symmetrically arranged on the left and right sides of the rubber pad 4. A threaded rod 6 is installed on the outside of the fixing plate 5. The threaded rod 6 is located in the middle of the support block 8. The lower part of the support block 8 is connected to the lower bottom plate 2. At the same time, a handle 7 is fixedly installed on the outside of the threaded rod 6. That is, manually rotating the handle 7 can make the threaded rod 6 threadedly connected with the support block 8. Thus, the threaded rod 6 can push the connected fixing plate 5 to closely fit on the outside of the rubber pad 4, which can enhance the installation stability of the rubber pad 4. At the same time, when it is necessary to replace the rubber pad 4, rotate the handle 7 again to make the threaded rod 6 and the support block 8 loose and separate, so that the fixing plate 5 is disengaged from the close contact with the rubber pad 4, that is, it is convenient to disassemble and replace the rubber pad 4.

[0033] Embodiment 2: For the existing seismic isolation rubber bearing, the fixed contact area between the upper and lower plates of the bearing and the equipment is fixed and cannot be enlarged, and problems such as enhancing the seismic isolation effect, as Figure 1 、 Figure 4 and Figure 6 As shown in Figure 1 , Figure 4 and Figure 6 , the mechanism for enhancing the seismic isolation effect includes a cylindrical shaft 13 arranged on the outside of the upper top plate 1 and the lower bottom plate 2. An expansion plate 14 is rotatably installed on the outside of the cylindrical shaft 13. The expansion plate 14 is fixed to the upper top plate 1 and the lower bottom plate 2 by screws 15. That is, unscrew the screws 15 and take them out, and then the expansion plate 14 can be rotated outward so that the expansion plate 14 rotates to be in a horizontal plane with the upper top plate 1 and the lower bottom plate 2. At the same time, after the screws 15 are pulled out, installation holes will be left inside the expansion plate 14, the upper top plate 1 and the lower bottom plate 2, which is convenient for bolt-fixed installation of the upper top plate 1, the lower bottom plate 2 and the expansion plate 14 with the upper equipment and the lower foundation embedment respectively.

[0034] Embodiment 3: For the existing seismic isolation rubber bearing, there are problems such as high processing cost, weak controllability and weak shear resistance, as Figure 2 and Figure 5As shown in the figure, the high bearing capacity tensile and anti-overturning functions include upper connecting inserts 9 arranged on the left and right sides below the upper top plate 1. Long circular holes are provided vertically inside the upper connecting inserts 9. At the same time, friction plates 10 are arranged on the outer sides of the upper connecting inserts 9. Circular holes are provided inside the friction plates 10. In addition, lower connecting inserts 11 are arranged on the outer sides of the friction plates 10. Long circular holes are provided horizontally inside the lower connecting inserts 11. The lower connecting inserts 11 are fixedly connected to the lower bottom plate 2 below. That is, when the tension or compression of the bearing exceeds the design value, the structure will move in the vertical direction. Therefore, the friction plates 10 provide a certain damping force for energy consumption. At the same time, the long circular holes define their displacements according to certain design values. This bearing can play a limiting role in the vertical direction and can play a tensile role when reaching the limit stroke. Secondly, the upper connecting inserts 9, the friction plates 10 and the lower connecting inserts 11 are fixedly connected by fastening bolts 12. That is, the fastening torque of the fastening bolts 12 can be adjusted, so as to set the required horizontal friction force. When the bearing moves horizontally or in other directions, the friction energy consumption reduces the vibration of the equipment. This rubber bearing has a compact structure, reliable connection, low processing cost, strong controllability, good shear resistance, flexible design. The specifications and dimensions of the shear resistance device can be freely designed according to requirements, and it has high bearing capacity, good unidirectional horizontal seismic isolation and certain tensile and anti-overturning functions.
