A Composite Support Structure Used for Lateral Seismic Resistance of Three-span Bridges

Abstract

The invention discloses a combined support structure for lateral seismic resistance of a three-span bridge, which includes an abutment, a traversing groove, and a bridge deck. There are multiple anti-seismic mechanisms extending into the traversing groove and against the bridge deck. The side walls at both ends of the abutment are provided with blocking mechanisms extending into the traversing groove and against the bridge deck. The sidewalls at both ends of the blocking mechanism are provided with draw-in slots, and the abutment is symmetrically provided with two pulling mechanisms extending into the draw-in slots opposite to it, and the abutment is provided with a plurality of wire take-up mechanisms. The structure design of the invention is reasonable, not only can play a good anti-seismic effect, avoid the internal structure of the bridge body from being damaged, but also can facilitate cleaning and refilling when the carbon sponge in the supporting structure is broken when the earthquake intensity is relatively high, Guarantee work efficiency.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of bridges, in particular to a combined support structure for lateral anti-seismic of three-span bridges. Background technique [0002] The earthquake damage of the bridge is due to the horizontal and vertical vibration of the bridge caused by the earthquake, causing damage and destruction of the bridge components, and even the collapse of the bridge. In the earthquake and earthquake disasters, the damage to the bridge is relatively large, so it is particularly important to improve the wind and earthquake resistance of the bridge. [0003] At present, the earthquake in the direction of the bridge is more harmful to the internal structure of the bridge body, and it is more likely to cause beam falling accidents. In the prior art, most of the bridges are reinforced by composite structures, and the structures are closely connected. When an earthquake occurs, no It can play a buffering role for...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the tight connection between bridge reinforcement structures in the prior art. When an earthquake occurs, the bridge body cannot be buffered, and it is easier to cause damage to the internal structure of the bridge body, and it is difficult to maintain it. problem, and a composite support structure for three-span bridge lateral seismic resistance is proposed, which can not only play a good seismic effect and avoid damage to the internal structure of the bridge body, but also can withstand large earthquake intensity and support structures. When the carbon sponge breaks, it is easy to clean and refill, ensuring work efficiency
