[0002] In building seismic isolation, an isolation layer is generally set at the foundation or bottom of the building structure to isolate and dissipate seismic energy. Its main function is to release the seismic energy in the isolation layer, thereby reducing the impact of the earthquake on the superstructure and reducing the destructiveness caused by the earthquake.

[0003] After searching, the patent number is CN203808279U, and the name is a utility model of a cylindrical metal rubber seismic isolation bearing, which includes an upper seat plate, a bearing body and a lower seat plate. Through research and analysis, it is found that although there will not be excessive deformation under the action of vertical load and the vibration period of the structure can be extended, there are still the following disadvantages to a certain extent.

[0004] For example, the component adopts the form of steel balls and steel plates for internal reinforcement, which can cope with vertical vibrations well. However, in actual application, earthquakes exist in two forms: longitudinal waves and transverse waves. The component cannot cope with horizontal vibrations well and cannot provide good buffering protection. The component has general buffering performance and does not have the function of split reinforcement. There are certain limitations. In order to solve the above technical problems, we have designed a cylindrical metal rubber seismic isolation bearing. Utility Model Content

[0020] See also Figure 1-Figure 4 A cylindrical metal rubber seismic isolation bearing comprises a mounting base 1, the number of mounting bases 1 is two, the four corners of the mounting base 1 surface are penetrated by anchoring mechanisms 3, the surface of the mounting base 1 is welded with a receiving ring 4, by setting the receiving ring 4, the end face of the metal rubber sleeve 2 can be assembled, and the installation stability of the metal rubber sleeve 2 is effectively improved, a reinforcement mechanism 5 is installed between the mounting base 1 and the receiving ring 4, and the metal rubber sleeve 2 is installed on the opposite side of the two receiving rings 4. By setting the metal rubber sleeve 2, the material itself can be used to have elasticity and damping performance similar to rubber, while maintaining the appearance and characteristics of metal, can adapt to extreme environments, and also has good damping characteristics, which can effectively absorb vibration energy, and the inner cavity of the metal rubber sleeve 2 is installed with an internal buffer protection mechanism 6;

[0021] See also Figure 1 and Figure 3 The anchor mechanism 3 includes an anchor frame 301. By setting the anchor frame 301, it can be pre-anchored into the concrete, and the shape design increases the contact installation area with the concrete, and the overall stability is better. One end of the anchor frame 301 is fixedly connected with a threaded head 302. The end of the threaded head 302 away from the anchor frame 301 passes through the installation base plate 1 and is threadedly sleeved with a lock nut 303. By setting the threaded head 302 and the lock nut 303, the role of thread transmission can be achieved. When the lock nut 303 is screwed in and locked, the installation base plate 1 will be stably installed.

[0022] See also Figure 1 and Figure 3 The reinforcement mechanism 5 includes two positioning seats 503, which are respectively welded to the mounting substrate 1 and the receiving ring 4;

[0023] See also Figure 1 and Figure 3 The surface of the positioning seat 503 is penetrated by a reinforcing bolt 502, and the surface thread sleeve of the reinforcing bolt 502 is provided with a reinforcing nut 501. By setting the reinforcing nut 501, the reinforcing bolt 502 and the positioning seat 503, the receiving ring 4 can be connected with the mounting base plate 1 during assembly, which not only frees the hands of personnel, but also eliminates the need for personnel to always maintain the receiving ring 4 and the mounting base plate 1 in an aligned state, and ensures the overall stability of the component in the installed state;

[0024] See also Figure 2 and Figure 4The inner buffer protection mechanism 6 includes a bearing plate 607 and a mounting base 601. By setting the mounting base 601, it is possible to simultaneously meet the requirements of fixing and installing multiple first springs 602 and the first spring 602. The outer ring of the bearing plate 607 is fixedly connected to the inner ring of the metal rubber sleeve 2. An elastic metal leaf 606 is welded on the top of the bearing plate 607. By setting the elastic metal leaf 606, it can contact the metal rubber sleeve 2. When the metal rubber sleeve 2 produces a lateral displacement, the elastic metal leaf 606 naturally elastically deforms inward, which has the function of auxiliary buffering.

[0025] See also Figure 2 and Figure 4 A reinforcing plate 604 is fixedly installed on the top of the bearing plate 607 and on the outside of the elastic metal leaf 606. By setting the reinforcing plate 604, the metal rubber sleeve 2 can be connected to the bearing plate 607, further improving the overall stability of the device, and the connection between the elastic metal leaf 606 and the bearing plate 607 can be positioned and covered. A second spring 603 is fixedly installed between the bearing plate 607 and the mounting base 601. By setting the second spring 603, it can play a role in auxiliary vertical buffering and improve the overall vertical buffering performance of the device;

[0026] See also Figure 2 and Figure 4 The surfaces of the bearing plate 607 and the mounting base 601 are fixedly connected with a protective convex ring 605 used in conjunction with the second spring 603. By providing the protective convex ring 605, the two ends of the second spring 603 can be covered and protected, which can reduce the swing caused by the large degree of freedom at the two ends, thereby improving the stability of the second spring 603. The outer ring of the mounting base 601 is fixedly connected with the first spring 602, and the other end of the first spring 602 is fixedly connected to the surface of the elastic metal leaf 606. By providing the first spring 602, it can be compressed during the earthquake shear wave to play a role of lateral buffer protection;

[0027] The connection between the outer ring of the reinforcing plate 604 and the metal rubber sleeve 2 and the connection between the outer ring of the bearing plate 607 and the metal rubber sleeve 2 are fixedly connected by vulcanization.

[0028] The topmost mounting base 601 is fixedly connected to the connection of the receiving ring 4, and the remaining mounting bases 601 are welded to the contacting bearing plate 607;

[0029] In practical application, the inner ring shape of the metal rubber sleeve 2 can be flexibly changed according to actual needs to increase the contact area between the metal rubber sleeve 2 and the elastic metal leaf 606 .

[0030] When in use, all components are in the initial state, the storage ring 4 and the metal rubber sleeve 2 are pre-vulcanized and connected in an integrated state, which is convenient for subsequent centralized transportation, and there is no need to assemble the metal rubber sleeve 2, the storage ring 4 and the internal buffer protection mechanism 6 on site. The anchor frame 301 is pre-buried in the concrete, and the threaded head 302 is in an exposed state. When in use, align the positioning seat 503 on the storage ring 4 with the positioning seat 503 on the mounting substrate 1, and then insert the reinforcement bolt 502 through the positioning seat 503 and sleeve the reinforcement nut 501 to stably connect the storage ring 4 to the mounting substrate 1. In order to improve the installation stability of the mounting substrate 1 and the storage ring 4, welding can also be used to reinforce the connection between the mounting substrate 1 and the storage ring 4, and then move the mounting substrate 1, so that the thread head 302 passes through the mounting base plate 1 and is screwed into the sleeve anti-loosening nut 303, so that the mounting base plate 1 is stably installed. When a longitudinal shock wave occurs, the metal rubber sleeve 2 is vertically compressed, and at the same time, the distance between the mounting base 601 and the bearing plate 607 is changed. The second spring 603 is compressed synchronously to achieve the effect of double vertical buffering protection. When a transverse shock wave occurs, the metal rubber sleeve 2 will produce a transverse displacement, so that the elastic metal leaf 606 is elastically deformed inwardly, and the first spring 602 is compressed synchronously to achieve a good transverse buffering effect. Moreover, since the first spring 602 and the elastic metal leaf 606 are designed as a ring array, a good buffering effect can be achieved when the transverse wave direction is not fixed, which is more in line with actual use requirements.

[0031] To sum up: the cylindrical metal rubber seismic isolation bearing, by setting the metal rubber sleeve 2, the storage ring 4, the reinforcement mechanism 5 and the internal buffer protection mechanism 6, solves the problem that the component cannot cope with horizontal vibrations well, cannot provide good buffering protection, the component has general buffering performance, and does not have the function of split reinforcement, which has certain limitations.
