Problems solved by technology

[0003] Although some bridges and piers can withstand the vibration force of the earthquake in terms of strength, due to the weak structural connection and poor integrity between the bridge and the piers, the structure between the bridge and the piers will often cause excessive relative displacement, resulting in bridge damage

Embodiment 1

[0032] Example 1: Reference Figure 1-3 , a replaceable socket-connected four-way limit damping tenon, including a first tenon assembly fixed on a bridge 10 and a second tenon assembly fixed on a bridge pier 9 . Both the first tenon assembly and the second tenon assembly are composed of stacked sandwich damping tenons 1 and limit ring damping arms 5 arranged at intervals. The stacked core damping tenon 1 in the first tenon assembly is inserted into the limit ring damping arm 5 in the second tenon assembly; the limit ring damping arm 5 in the first tenon assembly is inserted into the second clamp The stacked sandwich damping tenon 1 in the tenon assembly allows the first tenon assembly and the second tenon assembly to be inserted into each other to form an interlocking structure, preventing the bridge 10 and the pier 9 from being staggered. The stacked sandwich damping tenon 1 is embedded with a first lead plate 3 , and the limit ring damping arm 5 is embedded with a second le...

Embodiment 2

[0038] Embodiment 2, refer to Figure 1-6 , an installation method for a replaceable four-way limit damping tenon, comprising the following steps:

[0039]1. On the outside of the connection between pier 9 and bridge 10, select a flat horizontal mounting surface of pier 9 and a vertical mounting surface of bridge 10 for fixing the steel plate base;

[0040] 2. Install the steel plate base 8 on the vertical installation surface of the bridge 10 through bolts, and install the stacked core damping tenon 1 and the limit ring damping arm 5 on the steel plate base 8 by screwing at intervals to ensure that the limit ring damping arm 5. The opening direction of the limit ring at the end is perpendicular to the direction of the bridge 10;

[0041] 3. Install the steel plate base 8 on the horizontal installation surface of the pier 9 through bolts, and place the stacked sandwich damping tenon 1 and the limit ring damping arm 5 on the steel plate base 8 at intervals to ensure the horizo...

Abstract

The invention relates to a replaceable socket-connected four-way limit damping tenon and its installation method, which are applied in the technical field of bridge anti-seismic structures, and include a first tenon component fixed on the bridge and a first tenon component fixed on the bridge pier. The second bayonet assembly, the first bayonet assembly and the second bayonet assembly are inserted into each other, and the first bayonet assembly and the second bayonet assembly each include a plurality of stacked sandwich damping bayonets arranged at intervals and The limit ring damping arm, the head of the stacked core damping tenon is plugged into the limit ring damping arm, and the inside of the stacked core damping tenon and the limit ring damping arm are respectively embedded with a first lead plate and second lead sheet. The invention has the advantages of improving the stability between the bridge and the bridge pier, improving the seismic capacity of the bridge or the bridge pier in an earthquake, and adopting a replaceable design as a whole to facilitate maintenance after damage.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures of bridges, and more specifically relates to a replaceable four-way limit damping tenon and its installation method. Background technique [0002] The damage to bridges and bridge piers caused by earthquakes is mainly caused by surface damage and bridge damage caused by earthquakes. In steep mountainous areas or sandy soil and soft clay river banks, bridges can be damaged due to landslides, bank slope sliding and rock rolling caused by strong earthquakes. In the shallow saturated and loose sandy soil, the earthquake action can easily cause the sandy soil to liquefy, causing the bridge to sink suddenly or unevenly, or even topple the bridge. Earthquakes often cause bank slope slipping, cracking and collapse at the slope side soil bank or ancient river channel, resulting in bridge damage. [0003] Although some bridges and piers can withstand the vibration force of the earthquake i...
