Description

Technical Field

[0001] This utility model relates to the field of seismic isolation bearing technology, specifically a seismic isolation bearing with a fire protection mechanism. Background Technology

[0002] Seismic isolation bearings are important devices used in building structures. Their main function is to isolate seismic energy. When an earthquake occurs, seismic isolation bearings can effectively reduce the transmission of seismic waves from the foundation to the upper structure. Through their own deformation and damping characteristics, they dissipate seismic energy, which is like setting up a buffer zone between the building and the seismic waves. This reduces the damage of earthquakes to buildings, improves the safety of buildings during earthquakes, and helps protect people, equipment and items inside the building. They are widely used in various building projects that require earthquake resistance.

[0003] In existing technologies, the fire protection measures used for seismic isolation bearings usually involve wrapping fireproof cotton around the bearing and then sealing it with a fireproof board, with the fireproof cotton filling the space between the fireproof board and the bearing to provide protection. However, this design method causes the filled fireproof cotton to hinder the deformation of the bearing, increasing the stiffness of the bearing while reducing its flexibility and cushioning capacity. The bearing with limited deformation capacity will affect its seismic isolation performance.

[0004] Therefore, this utility model provides a seismic isolation bearing with a fire protection mechanism to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a seismic isolation bearing with a fire protection mechanism, such as... Figure 1 , Figure 2 and Figure 3 As shown, the seismic isolation bearing includes a lower support plate 1, a rubber bearing 3 fixedly installed on the top of the lower support plate 1, an upper support plate 2 fixedly installed on the top of the rubber bearing 3, a corrugated protective cover 4 sleeved on the side surface of the rubber bearing 3, an insert ring 5 fixedly installed on the top and bottom of the corrugated protective cover 4, and a connecting ring 6 fixedly installed on the top of the lower support plate 1 and the bottom of the upper support plate 2. The connecting ring 6 has a slot 7, and the insert ring 5 is inserted into the slot 7. The side surface of the connecting ring 6 has a groove 8, which is connected to the slot 7. The side surface of the insert ring 5 is fixedly connected to a locking block 9 that matches the groove 8, and the side surface of the locking block 9 is in contact with the inner wall of the groove 8.

[0025] The corrugated protective cover 4 is mainly made of a mixture of calcium, silicon and natural fiber materials. It has superior properties such as elasticity, fire resistance, earthquake resistance, impact resistance, aging resistance, corrosion resistance and strong stability. In the event of a fire, the corrugated protective cover 4 can effectively isolate the high-temperature heat source and prevent the rubber bearing 3 of the seismic isolation bearing from burning or being damaged due to high temperature. This ensures that the seismic isolation bearing can still work normally after the fire and maintain the seismic isolation performance of the building. During an earthquake, the rubber bearing 3 will deform under the seismic force. The corrugated protective cover 4 can adapt to the deformation of the rubber bearing 3 under its own characteristics, reducing the possibility of affecting the deformation of the rubber bearing 3.

[0026] The corrugated protective cover 4 needs to be fitted onto the side surface of the rubber bearing 3 during the production of the vibration isolation bearing. When installing the corrugated protective cover 4, the locking block 9 needs to be aligned with the locking groove 8, and then the insert ring 5 is directly inserted into the inside of the slot 7. At this time, the locking block 9 will also move inside the locking groove 8. When the locking block 9 comes into contact with the inner wall of the locking groove 8, the insert ring 5 needs to be rotated so that the locking block 9 continues to move inside the locking groove 8 until the locking block 9 reaches the end of the locking groove 8, thus completing the installation of the corrugated protective cover 4.

[0027] Furthermore, in order to improve the stability of the corrugated protective cover 4, such as Figure 3 , Figure 4 and Figure 5 As shown, a through hole is provided on the side surface of the connecting ring 6, and a threaded cylinder 10 is fixedly connected to the side surface of the connecting ring 6. The threaded cylinder 10 is coaxially arranged with the through hole, and the inner cavity of the threaded cylinder 10 is connected to the inner cavity of the slot 7 through the through hole.

[0028] The threaded cylinder 10 has a screw rod 11 screwed inside. One end of the screw rod 11 is fixedly connected to a handle 12. The end of the screw rod 11 away from the handle 12 extends through a through hole into the interior of the slot 7.

[0029] The side surface of the insertion ring 5 is provided with a insertion hole 15 that is adapted to the insertion rod 11, and one end of the insertion rod 11 extending into the slot 7 is inserted into the insertion hole 15.

[0030] When installing the corrugated protective cover 4, the locking block 9 needs to be engaged inside the locking groove 8. When the locking block 9 reaches the end of the locking groove 8, the insertion rod 11 is also aligned with the insertion hole 15. At this time, the operator can rotate the handle 12, which can drive the insertion rod 11 to move inside the threaded cylinder 10. After the insertion rod 11 is inserted into the insertion hole 15, the restriction of the insertion ring 5 is completed, thereby improving the stability of the corrugated protective cover 4.

[0031] Furthermore, to facilitate the workers in securing the corrugated protective cover 4, such as... Figure 2 , Figure 3 and Figure 5 As shown, a spring 13 is fixedly connected inside the slot 7. A pressure plate 14 is fixedly connected to one end of the spring 13. The side surface of the pressure plate 14 slides against the inner wall of the slot 7. The side of the pressure plate 14 away from the spring 13 is in contact with one end of the insertion ring 5.

[0032] Multiple springs 13 are provided, and the multiple springs 13 are arranged in a ring array with the rubber support 3 as the axis.

[0033] During the process of inserting the ring 5 into the slot 7, it will come into contact with the pressure plate 14 and press the pressure plate 14, while compressing the spring 13. After the corrugated protective cover 4 is installed, the spring 13 will always apply force to the pressure plate 14, so that the pressure plate 14 is in close contact with the ring 5, thereby increasing the friction between the two, reducing the possibility of misalignment between the insertion hole 15 and the insertion rod 11, and improving the stability of the ring 5, so as to facilitate the workers to fix the corrugated protective cover 4.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
