Description

Technical Field

[0001] The utility model relates to the technical field of damper installation, in particular to an installation structure of an anti-seismic damper. Background Art

[0002] Earthquakes and hurricanes are natural disasters that are unavoidable for human beings. Earthquakes and hurricanes can cause damage to bridge buildings, directly or indirectly threatening human lives. As bridges are indispensable road buildings today, how to improve their earthquake resistance and reduce the damage caused by earthquakes or hurricanes to bridges has become an important issue. Therefore, during the construction of existing bridge projects, seismic dampers are installed on the bridges to improve their overall earthquake resistance.

[0003] In order to facilitate the installation of the anti-seismic damper, the prior art has made many improvements to the installation structure of the anti-seismic damper. For example, the patent with the patent publication number CN215800969U discloses a device that can be used for bridge earthquake resistance, including a threaded rod cast in the bridge body, an anti-seismic damper and a nut threadedly connected to the threaded rod. Both ends of the anti-seismic damper are rotatably connected to a mounting seat, and a through hole is provided on the mounting seat. A guide rod is also cast on the side wall of the bridge body, and one end of the guide rod is fixedly connected to a guide block, and a slide groove matching the guide rod is provided on the mounting seat. By setting the pre-buried guide rod, guide block and slide groove, the mounting seat can be aligned by the guide rod and the guide block during installation, so that the through hole is aligned with the threaded rod, which facilitates the insertion of the threaded rod into the through hole, and the guide rod can share the tension borne by the threaded rod when the threaded rod is subjected to tension.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above patent document, a slide groove is provided on the existing mounting seat, and the slide groove cooperates with the guide block to guide and then align the mounting seat. However, in actual operation, the guide rod is installed in the bridge body by pre-embedding, and the pre-embedding method may cause the position of the guide rod to shift when pouring concrete. As long as the position of the guide rod shifts a little, it will increase the difficulty of the subsequent mounting seat. Therefore, there is an urgent need in this field to improve the mounting structure of the anti-seismic damper to solve the defects of the prior art. Utility Model Content

[0029] Specific implementation method of this embodiment: The above-mentioned seismic damper body 1 is an existing well-known technology. This embodiment mainly solves the problem of installing the seismic damper body 1. First, the mounting bolts 3 and one end of the guide rod 4 are pre-buried inside the bridge when the bridge is cast. The length of each guide rod 4 exposed from the bridge is longer than the length of the mounting bolt 3 exposed from the bridge. When the seismic damper body 1 needs to be installed on the cast bridge later, the mounting seat 2 needs to be installed first, and the mounting seat 2 is lifted by a lifting device, and the mounting seat 2 is close to the guide rod 4 and is sleeved on the side of the guide rod 4 through the clearance opening 6. Since the clearance opening 6 is much larger than the guide rod 4, it is very easy to sleeve the clearance opening 6 on the end of the guide rod 4, and then select the first adjustment rod 8 to adjust the plate according to the actual situation. 7 is adjusted, the adjusting plate 7 is against the side of the guide rod 4, and when the first adjusting rod 8 continues to be rotated, the auxiliary mounting plate 5 will be driven to move, and the position of the first adjusting rod 8 is limited by tightening the first limit nut 9, and the sliding block 10 is moved to adapt to the position of the guide rod 4, and the second adjusting rod 11 is rotated, and the end of the second adjusting rod 11 is against the side of the guide rod 4, and the auxiliary mounting plate 5 is driven to move by the reaction force, thereby realizing the adjustment of the mounting seat 2 in two directions, so that the mounting hole on the mounting seat 2 is aligned with the mounting bolt 3, and the mounting seat 2 is moved in the direction of the mounting bolt 3 by the lifting equipment, so as to facilitate the connection and installation between the mounting seat 2 and the mounting bolt 3. At the same time, even if the embedded guide rod 4 is offset, the mounting seat 2 can be guided and installed.

[0030] Embodiment 2

[0032] The specific implementation method of this embodiment is as follows: when the position of the sliding block 10 needs to be adjusted, the third adjusting rod 13 is rotated. The third adjusting rod 13 is threadedly connected to the sliding block 10, so when the third adjusting rod 13 is rotated, the sliding block 10 will be driven to slide in the sliding groove 12, and then the position of the sliding block 10 is adjusted. When the position of the sliding block 10 is adjusted, the second limiting nut 14 is tightened to limit the position of the third adjusting rod 13.
