Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an assembled building friction pendulum support. Background Art

[0002] The friction pendulum bearing is a high-performance seismic isolation bearing used in earthquake engineering. It combines the principles of friction pendulum and ball bearing, and can provide high-damping flexible support in the horizontal direction while maintaining the stability of the structure in the vertical direction. The main feature of the friction pendulum bearing is that when an earthquake occurs, it can allow the structure to slide freely in the horizontal direction, thereby reducing the damage to the building caused by seismic waves. Through seismic isolation design, the friction pendulum bearing helps to reduce the damage caused by earthquakes to buildings and reduce the cost of repair and reconstruction.

[0003] After searching, the announcement number CN216712713U discloses an assembled friction pendulum support, including a bottom plate and a top plate, a lower sliding block is provided at the top of the bottom plate, the bottom surface of the lower sliding block is provided with a plane sliding wear-resistant plate to form a plane sliding friction pair with the top surface of the bottom plate, an upper sliding block is provided at the bottom end of the top plate, the top surface of the lower sliding block is a downward concave spherical surface, and a spherical rotating wear-resistant plate is installed on the top surface of the lower sliding block to form a spherical rotating friction pair with the bottom end of the upper sliding block. Beneficial effects: The friction damping layer is a wear-resistant friction material made of ultra-high-pressure polytetrafluoroethylene fiber braid, Nomex, glass fiber or aramid fiber braid, which ensures that the design parts of the device have good wear resistance. The spring element further improves the shock absorption performance of the device. The designed fireproof components efficiently and reliably meet the requirements of non-degradation of the seismic isolation performance of the friction pendulum bearing under fire or secondary fire after the earthquake. In this application, the temperature displacement is made to slide on a plane with a small friction coefficient through structures such as the bottom plate and the lower sliding block, thereby increasing the service life. This arrangement makes it difficult to disassemble and assemble the external protective cover when maintaining the friction pendulum bearing, resulting in the inability to timely discover potential problems, which in turn affects the normal operation of the friction pendulum bearing.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3The utility model provides an embodiment: an assembled building friction pendulum bearing, comprising an upper bearing plate 1, a lower bearing plate 2 is arranged at the bottom of the upper bearing plate 1, a flexible protective ring 3 is attached to the outer wall of the lower bearing plate 2, one end of the flexible protective ring 3 is fixedly connected with a sub-buckle 4, the other end of the flexible protective ring 3 is fixedly connected with a female buckle 5, the outer wall of the sub-buckle 4 is slidably connected to the inner wall of the female buckle 5, a screw 6 is rotatably connected inside the flexible protective ring 3, a sliding sleeve 7 is threadedly connected to the outer wall of the screw 6, a connecting rod 8 is rotatably connected to the outer wall of the sliding sleeve 7, a slider 10 is fixedly connected to the outer wall of the flexible protective ring 3, the outer wall of the slider 10 is slidably connected to the inside of the upper bearing plate 1 and the lower bearing plate 2, one end of the connecting rod 8 is rotatably connected with a clamping block 9, the outer wall of the clamping block 9 is slidably connected to the inside of the slider 10, and a positioning component is arranged on the upper surface of the upper bearing plate 1;

[0024] Specifically, firstly, the flexible protective ring 3 is used to ensure that the connection between the upper support plate 1 and the lower support plate 2 has good sealing performance, so as to prevent external impurities and moisture from entering the interior of the friction pendulum support, thereby protecting the normal operation of the support and extending the service life. When assembling the flexible protective ring 3, it is first necessary to fit the flexible protective ring 3 to the outer walls of the upper support plate 1 and the lower support plate 2 to ensure that the protective ring fits tightly and has no gaps to ensure the sealing effect. Next, multiple sliders 10 are inserted into the interior of the upper support plate 1 and the lower support plate 2, and the displacement of the card block 9 is driven by the movement of the slider 10, thereby realizing the disassembly and assembly of the flexible protective ring 3, and then the flexible protective ring 3 is wrapped around the upper support plate 1 and the lower support plate 2, so that the protective ring fits more firmly on the support plate. In this step, it is necessary to ensure that the protective ring is wound evenly without twisting or folding to ensure its sealing performance. Finally, the sub-buckles 4 and the female buckles 5 at both ends of the flexible protective ring 3 are engaged to make the flexible protective ring 3 fit the outer walls of the upper support plate 1 and the lower support plate 2 for sealing to ensure the stability and sealing of the protective ring. By driving the screw 6 to rotate inside the flexible protective ring 3, due to the threaded relationship between the screw 6 and the sleeve 7, the sleeve 7 slides along the outer wall of the screw 6, thereby driving one end of the connecting rod 8 to move, and then driving the block 9 to slide out of the interior of the slider 10 through the other end of the connecting rod 8, and move to the interior of the upper support plate 1 and the lower support plate 2. During this process, the movement of the block 9 will drive the disassembly and assembly of the flexible protective ring 3, thereby facilitating the maintenance of the interior of the friction pendulum support.

[0025] Reference Figure 1 and Figure 4The positioning assembly includes a positioning block 13, the outer wall of the positioning block 13 is fixedly connected to the upper surface of the upper support plate 1, and the upper surface of the lower support plate 2 is slidably connected with a friction pendulum 12, the outer wall of the friction pendulum 12 is fixedly connected to the swing shaft 11, and the internal thread of the upper support plate 1 is connected with a threaded rod 15, one end of the threaded rod 15 is fixedly connected to a handle 14, and the other end of the threaded rod 15 is fixedly connected to a push block 16, the outer wall of the push block 16 is slidably connected to the inner wall of the positioning block 13, and the interior of the positioning block 13 is slidably connected with a sliding block 20, the outer wall of the sliding block 20 is fixedly connected to a telescopic rod 17, and the outer wall of the telescopic rod 17 is sleeved with a spring 18, and the two ends of the spring 18 are fixedly connected to the outer wall of the sliding block 20, and the interior of the positioning block 13 is fixedly connected to a limited block 19;

[0026] Specifically, first, the positioning block 13 is accurately inserted into the interior of the building to be installed to ensure that it is firmly and stably combined with the building, and then the handle 14 is driven. This action will drive the push block 16 to slide inside the positioning block 13. During the movement of the push block 16, a certain pressure will be applied to the sliding block 20. At this time, the spring 18 plays a vital role. It can not only provide the necessary elastic support to ensure that the sliding block 20 slides smoothly between the positioning block 13 and the interior of the building, but the movement process of the sliding block 20 is carefully designed, and it slides along the internal trajectory of the positioning block 13 to ensure that the sliding block 20 can accurately reach the predetermined position, thereby realizing the stable installation of the friction pendulum support. In this process, the limit block 19 plays a key role in limiting the moving range of the push block 16, which not only ensures the accuracy of the moving trajectory of the push block 16, but also effectively prevents the movement of the push block 16 from causing damage to the spring 18, thereby extending the service life of the entire positioning device.

[0027] Working principle: When it is necessary to use the prefabricated building friction pendulum bearing, first fit the flexible protective ring 3 to the outer wall of the upper bearing plate 1 and the lower bearing plate 2, then insert multiple sliders 10 into the upper bearing plate 1 and the lower bearing plate 2, and wrap the flexible protective ring 3 around the upper bearing plate 1 and the lower bearing plate 2, finally engage the sub-buckles 4 and the female buckles 5 at both ends of the flexible protective ring 3, so that the flexible protective ring 3 fits the outer wall of the upper bearing plate 1 and the lower bearing plate 2 for sealing, and then drive the screw 6 to rotate inside the flexible protective ring 3. Due to the threaded relationship between the screw 6 and the sleeve 7, the sleeve 7 slides along the outer wall of the screw 6, thereby driving one end of the connecting rod 8 to move, and then through The other end of the connecting rod 8 drives the card block 9 to slide out of the interior of the slider 10 and move to the interior of the upper support plate 1 and the lower support plate 2, thereby realizing the disassembly and assembly of the flexible protective ring 3, and then facilitating the maintenance of the interior of the friction pendulum support. Then the positioning block 13 is inserted into the interior of the building to be installed, and then the handle 14 is driven to drive the push block 16 to slide inside the positioning block 13, and then pressure is applied to the sliding block 20. In cooperation with the spring 18, the sliding block 20 slides between the positioning block 13 and the interior of the building, thereby realizing the disassembly and assembly of the friction pendulum support. In this process, the movement of the push block 16 is restricted by the limit block 19 to prevent the movement of the push block 16 from causing damage to the spring 18.
