An energy-consuming guardrail for bridges

Abstract

The invention relates to the field of bridge guardrails, in particular to an energy-consuming guardrail for bridges. Including bridge piers, bridge decks and bridge guardrails, the bridge guardrails are arranged on both sides of the bridge deck, and the outside of the bridge guardrails are provided with energy-consuming units at equal intervals, and the energy-consuming units are composed of mounting brackets, fixed blocks, sliders, It consists of several groups of piston cylinders, several groups of piston rods, several groups of shock-absorbing springs, several groups of exhaust pipes, several groups of connecting blocks and several groups of connecting ropes. The mounting frame is fixedly connected to the bridge deck, and the fixed blocks are vertically fixed. On the mounting frame, the piston end of a single group of the piston rod is located in the single group of the piston cylinder, and the other end of the single group of the piston rod is fixedly connected with the slider, the slider is located outside the bridge railing, the The shock-absorbing spring is sleeved on the piston rod, and the shock-absorbing spring is located between the piston cylinder and the slider. The technical solution is used to solve the problem that the bridge guardrail in the prior art has poor impact on the vehicle and cannot well prevent the vehicle from rushing out of the bridge guardrail.

Description

technical field [0001] The invention relates to the field of bridge guardrails, in particular to an energy-consuming guardrail for bridges. Background technique [0002] Most bridges are ubiquitous at high altitudes and are used to connect two high grounds, eliminating the time for people to detour. With the widespread popularity of bridges, bridge safety technologies have also been developed one after another. Gradually improving, the safety protection technology of municipal bridges is also gradually improving, and the anti-collision guardrail is also an important part of the bridge safety facilities. When an accident occurs, the existence of the anti-collision guardrail makes the impact of the traffic accident gradually reduced. [0003] However, it often plays a small role in safety protection when a traffic accident occurs. When a collision occurs, either the hardness of the guardrail is too large to cause the vehicle to be destructive, or the hardness is too small, an...
