[0002] Seismic isolation rubber bearings are applied to various building structures, highway bridges and structural reinforcements. They are made by alternately laminating multiple layers of steel plates and multiple layers of rubber with excellent bonding, and have a series of advantages such as good horizontal performance, damping coefficient, vertical performance and vertical bearing capacity.

[0003] In the utility model patent with the publication number CN 214459584 U, a pull-out protection device for a seismic isolation rubber bearing is proposed, which includes a seismic isolation rubber bearing body. The seismic isolation rubber bearing body is connected to a pre-embedded sleeve through a connecting bolt. A combined disc spring is sleeved on the connecting bolt. The upper end of the combined disc spring abuts against the head of the connecting bolt, and the lower end presses against the seismic isolation rubber bearing body. During use, the pre-embedded sleeve is pre-embedded in the structural concrete. This protection device can enable the rubber seismic isolation bearing to provide a pull-out prevention function, avoid the vertical bearing of the pull-out force on the bearing, and protect the seismic isolation rubber bearing from vertical damage.

[0004] In the actual use process of the above case, the connection between the seismic isolation bearing and the embedded part is realized through bolts, which not only has low installation efficiency, but also the bolts are easily eroded during long-term use, resulting in the problem of instability of the seismic isolation bearing. Therefore, the utility model provides a pre-embedded assembly of a seismic isolation bearing that is convenient for installation to meet the requirements. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] Optionally, the embedded part includes a pre-embedded column. The bottom of the pre-embedded column is fixedly connected with a central column. The bottom end of the central column is fixedly connected with a column tip. A sliding sleeve is slidably connected to the outside of the central column. The sliding sleeve is fixedly connected to the pre-embedded column through an elastic member.

[0008] Optionally, the number of the elastic members is four, and the four elastic members are annularly distributed with the central column as the center, and the elastic members are arc-shaped plates.

[0009] Optionally, the installation assembly includes a connecting seat arranged at the top end of the pre-embedded column, and a connecting rod is fixedly connected to the top of the connecting seat.

[0010] Optionally, the installation component further includes an installation cover. A reset spring is fixedly connected to the top of the inner cavity of the installation cover. The bottom of the reset spring is fixedly connected to a reset plate. Four fixing members are fixedly connected in a circular shape to the inner wall of the bottom of the inner cavity of the installation cover.

[0011] Optionally, four annularly distributed first sliding grooves are formed on the outer wall of the connecting rod. The first sliding grooves and the fixing members have the same "T" shape.

[0012] Optionally, four second sliding grooves are formed on the outer wall of the connecting rod. The height value of the second sliding groove is less than the height value of the first sliding groove. An annular groove is formed on the outside of the connecting rod. The bottoms of the second sliding groove and the first sliding groove are both communicated with the annular groove. A gasket is sleeved on the outside of the connecting rod. The gasket is located between the installation cover and the seismic isolation bearing installation plate.

[0013] Optionally, installation holes are formed at the four corners of the seismic isolation bearing installation plate on the top of the seismic isolation bearing main body. A threaded steel is clamped inside the installation hole. The bottom end of the threaded steel is fixedly connected to an external hexagonal screw.

This not only improves the construction efficiency but also facilitates the later maintenance and replacement. The operator only needs to insert the connecting rod into the installation cover according to the instructions and then rotate it to the fixed position to complete the installation. This simple operation method reduces the technical requirements for the operator and improves the construction efficiency.

[0016] In the above solution, the design of the sliding sleeve and the elastic member in the embedded part enables the embedded part to adapt to a certain degree of uneven settlement or deformation of the foundation. This adaptability enhances the stability and safety of the entire seismic isolation system. The reset spring and reset plate structure in the installation cover ensure the tight connection between the connecting rod and the fixing member, thereby improving the stability of the installation.

[0025] The following describes in detail a seismic isolation bearing embedded assembly for convenient installation provided by the present utility model with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0026] As Figures 1 to 4As shown in the figure, an embodiment of the utility model provides a shock isolation bearing embedded assembly that is convenient for installation, including a shock isolation bearing main body 1 and an embedded part 3. Shock isolation bearing mounting plates 2 are fixedly connected to both the top and bottom of the shock isolation bearing main body 1. An installation assembly 4 is used for the quick installation of the embedded part 3 and the shock isolation bearing main body 1. The installation assembly 4 is connected to the embedded part 3. The installation assembly 4 includes a connection seat arranged at the top end of the embedded column 301, and a connecting rod 401 is fixedly connected to the top of the connection seat. The installation assembly 4 further includes an installation cover 403. A return spring 404 is fixedly connected to the top of the inner cavity of the installation cover 403, and a return plate 405 is fixedly connected to the bottom of the return spring 404. Four fixing parts 406 are annularly and fixedly connected to the inner wall of the bottom of the inner cavity of the installation cover 403. Four annularly distributed first sliding grooves 407 are formed on the outer wall of the connecting rod 401. The shapes of the first sliding grooves 407 and the fixing parts 406 are the same, both being "T" shaped. Four second sliding grooves 408 are formed on the outer wall of the connecting rod 401. The height value of the second sliding grooves 408 is less than the height value of the first sliding grooves 407. An annular groove 409 is formed on the outer part of the connecting rod 401. Both the second sliding grooves 408 and the bottoms of the first sliding grooves 407 communicate with the annular groove 409. A gasket 402 is sleeved on the outer part of the connecting rod 401. The gasket 402 is located between the installation cover 403 and the shock isolation bearing mounting plate 2. First, ensure that the embedded part 3 has been embedded in the foundation structure according to the design requirements, and check whether its position, verticality, etc. meet the requirements. Connect the connecting rod 401 of the installation assembly 4 to the connection seat of the embedded part 3 to ensure a firm connection. Fit the installation cover 403 with the connecting rod 401 to ensure that the fixing parts 406 can smoothly enter the first sliding grooves 407. When the fixing parts 406 enter the inside of the annular groove 409 through the first sliding grooves 407, rotate the installation cover 403 so that the fixing parts 406 enter one end of the second sliding grooves 408. Then loosen the installation cover 403, and the fixing parts 406 will move upward under the driving force of the restoring force of the return spring 404 and then enter the inside of the second sliding grooves 408. Since there is no outlet at the other end of the second sliding grooves 408, the installation of the shock isolation bearing is completed. After the installation cover 403 is successfully installed, a stable connection is formed between the entire installation assembly 4 and the embedded part 3. At this time, the top end of the connecting rod 401 contacts the shock isolation bearing mounting plate 2 at the bottom of the shock isolation bearing main body 1, and the gasket 402 is located between the installation cover 403 and the shock isolation bearing mounting plate 2, playing a role of buffering and sealing.

[0027] In this embodiment, as Figures 1 to 4As shown, the embedded part 3 includes an embedded column 301. A central column 302 is fixedly connected to the bottom of the embedded column 301. A column tip 304 is fixedly connected to the bottom end of the central column 302. A sliding sleeve 303 is slidably connected to the outside of the central column 302. The sliding sleeve 303 is fixedly connected to the embedded column 301 through an elastic member 305. The number of elastic members 305 is four, and the four elastic members 305 are annularly distributed around the central column 302. And the elastic member 305 is an arc-shaped plate. The embedded part 3 is pre-installed in the building structure according to the design requirements to ensure that the column tip 304 penetrates into the foundation and is fixed. The sliding sleeve 303 and the elastic member 305 are installed on the central column 302 and adjusted to the appropriate positions. When the building structure is subjected to external forces (such as seismic forces), the sliding sleeve 303 will slide on the central column 302, generating a certain displacement to relieve the impact force. The elastic member 305 deforms when the sliding sleeve 303 displaces, providing buffering and supporting functions. After the external force disappears, the elastic restoring force of the elastic member 305 will cause the sliding sleeve 303 to return to the original position. When subjected to external forces (such as seismic forces), the sliding sleeve 303 will slide on the central column 302, generating a certain displacement to relieve the impact force. The elastic member 305, as an arc-shaped plate, has certain elasticity and deformation ability, and can provide a certain amount of buffering and support when the sliding sleeve 303 displaces, and can also cause the sliding sleeve 303 to return to its original position after the external force disappears. The column tip 304 penetrates into the foundation and is tightly combined with the foundation, providing good stability. The design of the sliding sleeve 303 and the elastic member 305 allows displacement when subjected to external forces, but the overall structure can still remain relatively stable, ensuring the reliability of the connection.

[0028] In this embodiment, as Figure 1As shown in the figure, mounting holes are provided at the four corners of the seismic isolation bearing mounting plate 2 at the top of the seismic isolation bearing main body 1. A threaded steel bar 6 is clamped inside the mounting hole. The bottom end of the threaded steel bar 6 is fixedly connected with an external hexagonal screw 5. The external thread of the threaded steel bar 6 is connected with a docking sleeve. The seismic isolation bearing mounting plate 2 is located between the external hexagonal screw 5 and the docking sleeve, and the number of threaded steel bars 6 on each right-angled side of the seismic isolation bearing mounting plate 2 is not less than two. This design enhances the connection stability between the seismic isolation bearing main body 1 and the upper structure. During installation, first pass the threaded steel bar 6 through the mounting hole into the seismic isolation bearing mounting plate 2, and then fix the external hexagonal screw 5 at the bottom end of the threaded steel bar 6 to ensure a firm connection between the threaded steel bar 6 and the seismic isolation bearing mounting plate 2. Then, thread the docking sleeve onto the external thread of the threaded steel bar 6. The design of the docking sleeve can match the connecting parts of the upper structure, so as to realize the tight connection between the seismic isolation bearing and the upper structure. Since the number of threaded steel bars 6 on each right-angled side is not less than two, this design increases the redundancy of the connection. Even if one of the threaded steel bars 6 is damaged or loosened, the other threaded steel bars 6 can still maintain the connection stability, ensuring the normal operation of the seismic isolation bearing under external forces such as earthquakes. The design of the external hexagonal screw 5 facilitates the tightening and adjustment of the threaded steel bar 6, and can be tightened or loosened according to actual needs to adapt to different connection requirements. The use of the docking sleeve increases the flexibility and versatility of the connection, can match different specifications and types of upper structure connecting parts, and improves the applicable range of the seismic isolation bearing. The design of this seismic isolation bearing embedded assembly realizes the rapid installation of the embedded part 3 and the seismic isolation bearing main body 1 through the installation assembly 4, and enhances the stability and buffering capacity of the seismic isolation bearing under external forces such as earthquakes through the design of the sliding sleeve 303 and the elastic part 305 in the embedded part 3. At the same time, the design of the mounting holes, the threaded steel bar 6, the external hexagonal screw 5, and the docking sleeve on the seismic isolation bearing mounting plate 2 ensures the connection stability and flexibility between the seismic isolation bearing and the upper structure, and improves the reliability and applicability of the entire seismic isolation system.

[0029] The working principle provided by the present utility model is to pre-install the embedded part 3 in the building structure according to the design requirements, ensure that the column tip 304 penetrates deep into the foundation and is fixed well, ensure that the embedded part 3 has been pre-embedded in the foundation structure according to the design requirements, and check whether its position, verticality, etc. meet the requirements. Connect the connecting rod 401 of the installation assembly 4 with the connecting seat of the embedded part 3 to ensure a firm connection. Fit the installation cover 403 with the connecting rod 401 to ensure that the fixing part 406 can smoothly enter the first chute 407. When the fixing part 406 enters the inside of the annular groove 409 through the first chute 407, rotate the installation cover 403 so that the fixing part 406 enters one end of the second chute 408. Then loosen the installation cover 403, and the fixing part 406 will move upward under the driving force of the restoring force of the return spring 404, and then enter the inside of the second chute 408. Since there is no outlet at the other end of the second chute 408, the installation of the seismic isolation bearing is completed.
