Abstract
Description
Technical Field
[0001] The utility model relates to a building structure, in particular to a shock absorbing structure. Background Art
[0002] Shock-absorbing bearings need to be installed in existing road bridges to reduce the risk of road bridge fractures during geological disasters such as earthquakes. For example, elastic support structures, such as rubber pads, can be installed between bridge piers and bridge spans to buffer and offset vibrations in the up and down directions. In addition, rotatable support arms can be installed between the bridge piers and the bridge spans to buffer and offset the forces transmitted along the length of the bridge span. However, in geological disasters, the forces transmitted to road bridges are in multiple directions, and the vibration directions that can be buffered and offset by existing road bridge shock-absorbing bearings are relatively single and cannot meet higher vibration and shock absorption requirements. Summary of the invention
[0003] The utility model aims to provide a shock-absorbing structure to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.
[0004] The solution of the utility model to solve the technical problem is:
[0005] The top end of the lifting plug in the lifting plug has a spring, and the bottom end of the lifting plug has a spring, and the bottom end of the lifting plug has a spring, and the bottom end of the lifting plug has a spring.
[0006] The technical solution has at least the following beneficial effects: during installation, the upper mounting plate is fixed to an external building structure, such as a bridge span. At this time, the upper mounting plate, the upper mounting seat, the connecting tube, and the connecting ring form a whole module. The whole module is fixed on the bridge span, and the lower mounting seat is installed on the external building structure below the upper mounting plate, such as a bridge pier. During use, when vibration is transmitted from the bridge span or the bridge pier to between the upper mounting seat and the lower mounting seat, the elastomer between the upper mounting seat and the lower mounting seat can produce elastic deformation to offset the vibration in the up and down directions. In each connecting unit, the limit rod can slide radially in the connecting ring, and the limit rod will compress the elastic member. The elastic member can be used to buffer the vibration in the straight line direction where the limit rod is located. In this way, multiple connecting units connected between the lower mounting seat and the connecting ring can buffer and offset the vibration transmitted in multiple different directions. Therefore, the utility model greatly improves the shock absorption performance in the three-dimensional direction, thereby improving the protection effect on the building structure.
[0007] As a further improvement of the above technical solution, a buffer layer is further provided between the connecting ring and the lower mounting plate. The lower mounting plate can support the connecting ring through the buffer layer, thereby further improving the buffering and shock absorption in the three-dimensional direction.
[0008] As a further improvement of the above technical solution, the shape of the bottom surface of the upper mounting seat is an arc with an opening downward, the shape of the top surface of the lower mounting seat is an arc with an opening upward, the top surface of the elastomer is tightly attached to the bottom surface of the upper mounting seat, and the bottom surface of the elastomer is tightly attached to the top surface of the lower mounting seat. When the upper mounting seat and the lower mounting seat are subjected to horizontal vibration, the connecting unit can be used to buffer and offset the vibration. At this time, a relative displacement in the horizontal direction will occur between the upper mounting seat and the lower mounting seat. Due to the design that the middle part of the bottom surface of the upper mounting seat is arched upward and the middle part of the top surface of the lower mounting seat is arched downward, when the upper mounting seat and the lower mounting seat are relatively displaced, the elastic body will also slide relative to the upper mounting seat or the lower mounting seat, or between the upper mounting seat and the lower mounting seat at the same time. At this time, the upper mounting seat and the lower mounting seat will squeeze the elastic body, thereby also playing a role of shock absorption and buffering. After the shock absorption and buffering are completed, the elastic body needs to release the elastic force and the elastic force of the elastic part in the connecting unit so that the upper mounting seat and the lower mounting seat are facing each other again. At this time, the elastic body also returns to between the middle part of the upper mounting seat and the middle part of the lower mounting seat.
[0009] As a further improvement of the above technical solution, an upper elastic seat is further provided between the bottom side of the upper mounting seat and the top side of the elastic body, the top surface of the upper elastic seat is in close contact with the bottom surface of the upper mounting seat, the bottom surface of the upper elastic seat is in the shape of an arc opening downward, and the top surface of the elastic body is in close contact with the bottom surface of the upper elastic seat. An upper elastic seat is further provided between the elastic body and the upper mounting seat, and when the upper mounting seat and the lower mounting seat are vibrated and produce relative displacement in the horizontal direction, the elastic body will produce relative displacement with the upper elastic seat, and the upper elastic seat will also produce relative displacement with the upper mounting seat, at which time the elastic body and the upper elastic seat are both squeezed and deformed, thereby achieving shock absorption and buffering, which can further enhance the overall shock absorption and buffering performance.
[0010] As a further improvement of the above technical solution, a lower elastic seat is further provided between the top side of the lower mounting seat and the bottom side of the elastic body, the bottom surface of the lower elastic seat is in close contact with the top surface of the lower mounting seat, the top surface of the lower elastic seat is in the shape of an arc with an opening facing upward, and the bottom surface of the elastic body is in close contact with the top surface of the lower elastic seat. Similarly, a lower elastic seat is further provided between the elastic body and the lower mounting seat, and when the upper mounting seat and the lower mounting seat are vibrated and produce relative displacement in the horizontal direction, relative displacement occurs between the elastic body and the lower elastic seat, and relative displacement also occurs between the lower elastic seat and the lower mounting seat, and the elastic deformation produced by the extrusion of the lower elastic seat is used to further achieve shock absorption and buffering, thereby enhancing the overall performance.
[0011] As a further improvement of the above technical solution, an upper rib is arranged around the bottom edge of the upper elastic seat, and a lower rib is arranged around the top side of the lower elastic seat, and the friction coefficient between the elastomer and the upper elastic seat is different from the friction coefficient between the elastomer and the lower elastic seat. Due to the different friction coefficients between the elastomer and the upper elastic seat and the lower elastic seat, when buffering the vibration transmitted in the horizontal direction, a multi-stage shock absorption and buffering effect will be presented. For example, when the friction coefficient between the elastomer and the upper elastic seat is less than the friction coefficient between the elastomer and the lower elastic seat, the elastomer will have a relative displacement with the upper elastic seat with a relatively small friction coefficient, and when the vibration is large, the elastomer will continue to drive the upper elastic seat to move after sliding to the upper rib, so that the elastomer and the lower elastic seat with a relatively large friction coefficient will also have a relative displacement, so as to achieve further shock absorption and buffering. In this way, multi-stage shock absorption and buffering are achieved, which meets the shock absorption needs of different vibration sizes, thereby greatly improving the overall shock absorption performance.
[0012] As a further improvement of the above technical solution, an upper peripheral edge is arranged around the bottom edge of the upper mounting seat, and a lower peripheral edge is arranged around the top edge of the lower mounting seat. When relative displacement occurs between the upper elastic seat and the upper mounting seat, the upper peripheral edge can limit the movable stroke of the upper elastic seat to prevent the upper elastic seat from moving out of the upper mounting seat. Similarly, the lower peripheral edge can limit the relative displacement of the lower elastic seat on the lower mounting seat to prevent the lower elastic seat from moving out of the lower mounting seat.
[0013] As a further improvement of the above technical solution, the connection ring is provided with a limit hole and a mounting hole that are interconnected, the elastic member is located in the limit hole, and the limit rod is located in the mounting hole. One end of the elastic member is inserted into the limit hole for positioning, thereby improving the structural stability of the elastic member installed in the connection ring, and the mounting hole can limit the sliding position of the limit rod. When the limit rod moves in the mounting hole, the elastic member is compressed, thereby achieving the effect of shock absorption and buffering. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them.

In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.
[0019] Reference Figure 1 A shock absorbing structure, in the first embodiment, comprises: an upper mounting plate 11; a connecting tube 13, which is connected to the bottom side of the upper mounting plate 11, and the bottom end of the connecting tube 13 is connected to a connecting ring 14; an upper mounting seat 12, which is connected to the bottom side of the upper mounting plate 11 and located inside the connecting tube 13; a lower mounting plate 5, which is located below the connecting ring 14; a lower mounting seat 2, which is located on the top side of the lower mounting plate 5, and the lower mounting seat 2 passes upward through the inside of the connecting ring 14; an elastic body 3, which is located at the bottom side of the upper mounting seat 12 and the elastic body 3. Between the top sides of the lower mounting seat 2; a connecting unit, which includes a limit rod 41 and an elastic member 42, the limit rod 41 is slidably connected in the connecting ring 14, the limit rod 41 can move radially along the lower mounting seat 2, one end of the elastic member 42 abuts against an end of the limit rod 41 away from the lower mounting seat 2, and the other end of the elastic member 42 abuts against the inner side of the lower mounting seat 2, the elastic member 42 presses the limit rod 41 toward the lower mounting seat 2, and a plurality of the connecting units are arranged around the lower mounting seat 2 at intervals.
[0020] When installing this shock-absorbing structure, the upper mounting plate 11 is fixed to an external building structure, such as a bridge span. At this time, the upper mounting plate 11, the upper mounting seat 12, the connecting tube 13, and the connecting ring 14 form a whole module, and the whole module is fixed to the bridge span, and the lower mounting seat 2 is installed on the external building structure located below the upper mounting plate 11, such as a bridge pier. When in use, when the vibration is transmitted from the bridge span or the bridge pier to the upper mounting seat 12 and the lower mounting seat 2, the elastic body 3 located between the upper mounting seat 12 and the lower mounting seat 2 can produce elastic deformation , to offset the vibration in the up and down directions, and in each connecting unit, the limiting rod 41 can slide radially in the connecting ring 14, and the limiting rod 41 will compress the elastic member 42, and the elastic member 42 can be used to buffer the vibration in the straight line direction of the limiting rod 41, so that the multiple connecting units connected between the lower mounting seat 2 and the connecting ring 14 can buffer and offset the vibration transmitted in multiple different directions. Therefore, the utility model greatly improves the shock absorption performance in the three-dimensional direction, thereby improving the protection effect on the building structure.
[0021] In order to further improve the overall elastic buffering effect, in this embodiment, a buffer layer 51 is further provided between the connecting ring 14 and the lower mounting plate 5. The lower mounting plate 5 can support the connecting ring 14 through the buffer layer 51, further improving the buffering and shock absorption in the three-dimensional direction.
[0022] The elastic body 3 and the elastic member 42 mainly play an elastic buffering role. For example, the elastic body 3 can be made of rubber material, and the elastic member 42 can also be made of rubber material, or a spring.
[0023] The top surface and the bottom surface of the elastic body 3 can be directly connected to the upper mounting seat 12 and the lower mounting seat 2. When performing shock absorption and buffering, the elastic body 3 can directly rely on the elastic deformation generated by its own torsion and compression to achieve buffering. The elastic body 3 may not be fixed to the upper mounting seat 12 and the lower mounting seat 2. Specifically, Figure 2As shown, in embodiment 2, the shape of the bottom surface of the upper mounting seat 12 is an arc with an opening facing downward, the shape of the top surface of the lower mounting seat 2 is an arc with an opening facing upward, the top surface of the elastomer 3 is tightly attached to the bottom surface of the upper mounting seat 12, and the bottom surface of the elastomer 3 is tightly attached to the top surface of the lower mounting seat 2. When the upper mounting seat 12 and the lower mounting seat 2 are subjected to horizontal vibration, the connecting unit can be used to buffer and offset the vibration. At this time, a relative displacement in the horizontal direction will occur between the upper mounting seat 12 and the lower mounting seat 2. Due to the design that the middle part of the bottom surface of the upper mounting seat 12 is arched upward and the middle part of the top surface of the lower mounting seat 2 is arched downward, when the upper mounting seat 12 and the lower mounting seat 2 are relatively displaced, the elastic body 3 will also slide relative to the upper mounting seat 12 or the lower mounting seat 2, or between the upper mounting seat 12 and the lower mounting seat 2 at the same time. At this time, the upper mounting seat 12 and the lower mounting seat 2 will squeeze the elastic body 3, thereby also playing a role of shock absorption and buffering. After the shock absorption and buffering are completed, the elastic body 3 needs to release the elastic force and the elastic force of the elastic member 42 in the connecting unit so that the upper mounting seat 12 is aligned with the lower mounting seat 2 again. At this time, the elastic body 3 also returns to between the middle part of the upper mounting seat 12 and the middle part of the lower mounting seat 2.
[0024] In order to further improve the overall shock absorption and buffering performance, in this embodiment, an upper elastic seat 31 is further provided between the bottom side of the upper mounting seat 12 and the top side of the elastic body 3, the top surface of the upper elastic seat 31 is in close contact with the bottom surface of the upper mounting seat 12, the bottom surface of the upper elastic seat 31 is in the shape of an arc with an opening facing downward, and the top surface of the elastic body 3 is in close contact with the bottom surface of the upper elastic seat 31. An upper elastic seat 31 is further provided between the elastic body 3 and the upper mounting seat 12, when the upper mounting seat 12 and the lower mounting seat 2 are vibrated and produce relative displacement in the horizontal direction, the elastic body 3 will produce relative displacement with the upper elastic seat 31, and the upper elastic seat 31 will also produce relative displacement with the upper mounting seat 12, at this time, the elastic body 3 and the upper elastic seat 31 are both squeezed and deformed, thereby achieving shock absorption and buffering, which can further enhance the overall shock absorption and buffering performance.
[0025] Furthermore, a lower elastic seat 32 is provided between the top side of the lower mounting seat 2 and the bottom side of the elastic body 3, the bottom surface of the lower elastic seat 32 is in close contact with the top surface of the lower mounting seat 2, the top surface of the lower elastic seat 32 is in an arc shape with an opening facing upward, and the bottom surface of the elastic body 3 is in close contact with the top surface of the lower elastic seat 32. Similarly, a lower elastic seat 32 is provided between the elastic body 3 and the lower mounting seat 2, and when the upper mounting seat 12 and the lower mounting seat 2 are vibrated and produce relative displacement in the horizontal direction, relative displacement occurs between the elastic body 3 and the lower elastic seat 32, and relative displacement also occurs between the lower elastic seat 32 and the lower mounting seat 2, and the elastic deformation produced by the extrusion of the lower elastic seat 32 is used to further realize shock absorption and buffering, thereby enhancing the overall performance.
[0026] In the above embodiment, the upper elastic seat 31 and the lower elastic seat 32 can be made of the same material. At this time, when relative displacement occurs between the elastomer 3 and the upper elastic seat 31 and the lower elastic seat 32, the upper elastic seat 31 and the lower elastic seat 32 move in synchronous reverse directions. When the upper elastic seat 31 and the lower elastic seat 32 are made of different materials, the whole can achieve multi-level shock absorbing and buffering effects. The bottom edge of the upper elastic seat 31 is surrounded by an upper retaining edge 311, and the top side of the lower elastic seat 32 is surrounded by a lower retaining edge 321. The friction coefficient between the elastomer 3 and the upper elastic seat 31 is different from the friction coefficient between the elastomer 3 and the lower elastic seat 32. Due to the different friction coefficients between the elastomer 3 and the upper elastic seat 31 and the lower elastic seat 32, when buffering the vibration transmitted in the horizontal direction, a multi-level shock absorbing and buffering effect will be presented. For example, when the friction coefficient between the elastomer 3 and the upper elastic seat 31 is smaller than the friction coefficient between the elastomer 3 and the lower elastic seat 32, the elastomer 3 will have a relative displacement with the upper elastic seat 31 with a relatively small friction coefficient. When the vibration is large, the elastomer 3 slides to the upper retaining edge 311 and continues to drive the upper elastic seat 31 to move, so that the elastomer 3 and the lower elastic seat 32 with a relatively large friction coefficient are also relatively displaced, thereby achieving further shock absorbing and buffering. In this way, multi-level shock absorbing and buffering are achieved, which meets the shock absorbing needs of different vibration sizes, thereby greatly improving the overall shock absorbing performance.
[0027] In practical applications, for example, when the friction coefficient between the elastic body 3 and the upper elastic seat 31 is less than the friction coefficient between the elastic body 3 and the lower elastic seat 32, the elastic body 3 drives the upper elastic seat 31 to move on the upper mounting seat 12, and there may be a problem that the upper elastic seat 31 moves to the edge of the upper mounting seat 12. Therefore, in order to improve the overall structural stability, the bottom edge of the upper mounting seat 12 is surrounded by an upper peripheral edge 121, and the top edge of the lower mounting seat 2 is surrounded by a lower peripheral edge 21. When relative displacement occurs between the upper elastic seat 31 and the upper mounting seat 12, the upper peripheral edge 121 can limit the movable stroke of the upper elastic seat 31 to prevent the upper elastic seat 31 from moving out of the upper mounting seat 12. Similarly, the lower peripheral edge 21 can limit the relative displacement of the lower elastic seat 32 on the lower mounting seat 2 to prevent the lower elastic seat 32 from moving out of the lower mounting seat 2.
[0028] For the installation of the elastic member 42 and the limiting rod 41 in the connecting ring 14, a hole with a uniform inner diameter can be directly set in the connecting ring 14, and then the elastic member 42 and the limiting rod 41 can be installed in the hole. In this embodiment, the connecting ring 14 is provided with a limiting hole and a mounting hole that are interconnected, the elastic member 42 is located in the limiting hole, and the limiting rod 41 is located in the mounting hole. One end of the elastic member 42 is inserted into the limiting hole for positioning, thereby improving the structural stability of the elastic member 42 installed in the connecting ring 14, and the mounting hole can limit the sliding of the limiting rod 41. When the limiting rod 41 moves in the mounting hole, it will compress the elastic member 42, thereby achieving the effect of shock absorption and buffering.
