Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering technology, and in particular to a high-performance combined seismic isolation bearing. Background Technology
[0002] Chinese patent document CN221276921 U discloses a high-performance combined seismic isolation bearing, including a laminated seismic isolation rubber part and a metal damper part. By combining the metal damper and the laminated seismic isolation rubber bearing, the equivalent damping ratio of the seismic isolation rubber bearing is improved through the synergistic deformation of the two, and the seismic isolation effect is more obvious. Moreover, under rare or extremely rare earthquakes, the U-shaped damper is straightened, which plays a certain role in tensile resistance and limiting protection. At the same time, the metal damper, as an additional part, is easy to install and replace.
[0003] However, when the aforementioned seismic isolation bearings are only partially damaged after a disaster, the entire bearing becomes unusable due to its integrated installation, leading to high maintenance costs due to the need for complete replacement. Therefore, we propose a high-performance combined seismic isolation bearing. Utility Model Content
[0004] The purpose of this invention is to provide a high-performance combined seismic isolation bearing that can solve the problem that some existing seismic isolation bearings are expensive to replace when partially damaged.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance combined seismic isolation bearing, comprising:
[0006] The fixing plates consist of two sets. On the side of each set of fixing plates that are close to each other, there is a set of mounting frames. Each set of mounting frames contains a set of mounting plates that are in contact with its inner wall. A rubber layer is fixedly installed between the two sets of mounting plates.
[0007] The auxiliary mechanism, which is set between the two sets of fixed plates, is used to assist the support in resisting earthquakes.
[0008] The snap-fit mechanism is set on two sets of mounting frames. The snap-fit mechanism includes a U-shaped snap rod and a pad. A set of U-shaped snap rods is movably inserted through each set of mounting frames. The two sets of U-shaped snap rods are also movably inserted through the corresponding mounting plates. A set of pads is fixedly installed on the front outer surface of each set of mounting frames. The two sets of U-shaped snap rods abut against the corresponding pads.
[0009] Preferably, the snap-fit mechanism further includes threaded sections and first bolts. Both ends of the two sets of pads are provided with a set of threaded sections that extend to the rear side of the corresponding mounting frame. A set of first bolts is threaded onto each of the four sets of threaded sections. Under the action of the snap-fit mechanism, each part of the seismic isolation bearing can be replaced individually. If some parts are damaged due to a disaster, they can be replaced individually, and other intact parts can be reused, reducing maintenance costs. This solves the problem that when some existing seismic isolation bearings are only partially damaged after a disaster, they are scrapped as a whole due to their integrated installation, resulting in high maintenance costs for overall replacement. This improves the practicality of the seismic isolation bearing.
[0010] Preferably, the auxiliary mechanism includes a fixed block, a U-shaped damper, a threaded rod, and a second bolt. Four sets of fixed blocks are fixedly installed on the side of the two sets of fixed plates that are close to each other, and are evenly distributed at the four corners of each mounting surface. Four sets of U-shaped dampers are arranged between the two sets of fixed plates. A set of threaded rods is fixedly installed at both ends of the four sets of U-shaped dampers. The cross-sectional diameter of the threaded rods is smaller than the cross-sectional diameter of the U-shaped dampers. Each set of threaded rods moves through the corresponding fixed block. Both ends of the four sets of U-shaped dampers abut against the corresponding fixed blocks. A set of second bolts is threaded onto each set of threaded rods.
[0011] Preferably, two sets of handle pads are fixedly installed on the side of the two sets of fixing plates that are close to each other.
[0012] Preferably, both sets of fixing plates have at least two sets of mounting holes.
[0013] Preferably, a microcapsule repair agent is pre-embedded in the rubber layer, and the microcapsule repair agent is used to automatically release repair material when cracks occur in the rubber layer.
[0014] Preferably, the outer surface of the rubber layer is covered with a fire-retardant coating.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) This high-performance combined seismic isolation bearing, through the snap-fit mechanism, allows each part of the seismic isolation bearing to be replaced individually. When some parts are damaged due to disasters, they can be replaced individually and other intact parts can be reused, reducing maintenance costs. This solves the problem that when some existing seismic isolation bearings are only partially damaged after a disaster, they are scrapped as a whole due to their integrated installation, resulting in high maintenance costs for overall replacement. This improves the practicality of the seismic isolation bearing.
[0017] (2) The high-performance combined seismic isolation bearing, through the cooperation of the snap-fit mechanism and the auxiliary mechanism, can also replace the rubber layer and U-shaped damper of different sizes to adapt to different building spaces, ensuring the effectiveness of the seismic isolation bearing and facilitating the promotion and use of the device.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Please see Figure 1-3 This utility model provides a technical solution: a high-performance combined seismic isolation bearing, including a fixing plate 1, an auxiliary mechanism 6 and a snap-fit mechanism 5. There are two sets of fixing plates 1. A set of mounting frames 2 are fixedly installed on the side of the two sets of fixing plates 1 that are close to each other. A set of mounting plates 3 that are close to the inner wall of each set of mounting frames 2 is placed in each set of mounting frames 2. A rubber layer 4 is fixedly installed between the two sets of mounting plates 3. The auxiliary mechanism 6 is set between the two sets of fixing plates 1. The auxiliary mechanism 6 is used to assist the bearing in seismic resistance. Two sets of handle pads 7 are fixedly installed on the side of the two sets of fixing plates 1 that are close to each other. At least two sets of mounting holes 8 are opened through the two sets of fixing plates 1. Microcapsule repair agent is pre-embedded in the rubber layer 4. The microcapsule repair agent is used to automatically release repair material when the rubber layer 4 cracks. The outer surface of the rubber layer 4 is covered with a fireproof coating.
[0025] The snap-fit mechanism 5 is set on the two sets of mounting frames 2. The snap-fit mechanism 5 includes a U-shaped snap rod 51 and a pad 52. A set of U-shaped snap rods 51 is movably passed through each of the two sets of mounting frames 2. The two sets of U-shaped snap rods 51 are also movably passed through the corresponding mounting plates 3. A set of pads 52 is fixedly installed on the front outer surface of each of the two sets of mounting frames 2. The two sets of U-shaped snap rods 51 abut against the corresponding pads 52.
[0026] The snap-fit mechanism 5 also includes threaded sections 53 and first bolts 54. Both ends of the two sets of pads 52 are provided with a set of threaded sections 53 and extend to the rear side of the corresponding mounting frame 2. A set of first bolts 54 are threaded on each of the four sets of threaded sections 53. Through the snap-fit mechanism 5, each part of the seismic isolation bearing can be replaced individually. If some parts are damaged due to disasters, they can be replaced individually and other intact parts can be reused, reducing maintenance costs. This solves the problem that when some existing seismic isolation bearings are only partially damaged after a disaster, they are scrapped as a whole due to their integrated installation, resulting in high maintenance costs for overall replacement. This improves the practicality of the seismic isolation bearing.
[0027] The auxiliary mechanism 6 includes a fixing block 61, a U-shaped damper 62, a threaded rod 63, and a second bolt 64. Four sets of fixing blocks 61 are fixedly installed on the side of each of the two sets of fixing plates 1 that are close to each other, and are evenly distributed at the four corners of each mounting surface. Four sets of U-shaped dampers 62 are arranged between the two sets of fixing plates 1. A set of threaded rods 63 is fixedly installed at both ends of each of the four sets of U-shaped dampers 62. The cross-sectional diameter of the threaded rods 63 is smaller than that of the U-shaped dampers 62. Each set of threaded rods 63 moves through the corresponding fixing block 61. Both ends of the four sets of U-shaped dampers 62 abut against the corresponding fixing block 61. A set of second bolts 64 is threaded onto each set of threaded rods 63. Through the cooperation of the snap-fit mechanism 5 and the auxiliary mechanism 6, the seismic isolation bearing can be fitted with rubber layers 4 and U-shaped dampers 62 of different sizes to adapt to different building spaces, ensuring the effectiveness of the seismic isolation bearing and facilitating the promotion and use of the device.
[0028] Working principle: The entire seismic isolation bearing is installed through the mounting hole 8. In the event of local damage after a disaster, the first bolt 54 can be removed, the U-shaped clamp 51 can be pulled out, the second bolt 64 can be removed, and the U-shaped damper 62 can be taken off, so that the two sets of fixing plates 1 and rubber layer 4 are separated, and the damaged parts can be replaced. During installation, rubber layer 4 and U-shaped damper 62 of different sizes can be reinstalled according to different building spaces.
[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
