Embodiment 1

[0024] refer to Figure 1 to Figure 4 , the bridge shock absorber is used to be arranged at the junction of the pier 13 and the beam body 11, including an inner hoop 21, an outer hoop 22, a shock absorber bracket and a flange ring 23, and between the inner hoop 21 and the outer hoop 22 Connected into one body by the shock-absorbing bracket, the flange ring 23 is vertically fixed on the top of the outer hoop 22,

[0025] Among them, the pier 13 and the beam body 11 are provided with a support 12,

[0026] The outer hoop 22 surrounds the support 12;

[0027] The flange ring 23 is fixed on the bottom surface of the beam body 11 above the support 12 by bolts;

[0028] The inner hoop 21 surrounds the outer side of the pier 13 and reserves a telescopic gap between the pier 13 and the pier 13 which can play a shock-absorbing role.

[0029] As a specific embodiment, the top outer rings of the left semi-circular part and the right semi-circular part of the outer hoop 22 protrude out...

Abstract

The invention discloses a bridge shock absorber which comprises an inner hoop, an outer hoop, a shock absorption support and a flange ring, and the inner hoop and the outer hoop are each formed by splicing a left semi-arc piece and a right semi-arc piece; the left semi-arc piece of the inner hoop and the left semi-arc piece of the outer hoop are connected into a whole through the shock absorption support; the right semi-arc piece of the inner hoop and the right semi-arc piece of the outer hoop are connected into a whole through the shock absorption support; and the flange ring is vertically fixed to the top end of the outer hoop. The invention discloses a bridge shock absorber which can meet the requirement for support replacement, has a good energy dissipation capacity, can respond to 360-degree displacement of a beam body, enables sliding piers to participate in cooperative shock resistance, is beneficial to preventing the beam body from sliding off and is suitable for new construction and seismic reinforcement of railway bridges, highway bridges, urban viaducts and various continuous beam bridges.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge shock absorber. Background technique [0002] In order to reduce the seismic response of continuous girder bridges and improve the seismic performance of continuous girder bridges, shock-absorbing measures such as shock-absorbing and isolating bearings and viscous dampers are usually used for continuous girder bridges, such as lead rubber bearings, viscous dampers, etc. . However, for the existing pier-column continuous girder bridge, the beam body needs to be jacked up when using shock-absorbing and isolating bearings for aseismic reinforcement, which is inconvenient for construction. For new bridges, not only the use of shock-absorbing and isolating bearings will face the problem of difficult maintenance and replacement, but the use of viscous dampers will also increase the difficulty of bearing replacement. [0003] On the other hand, the seismic capacity of convent...
