Abstract

The invention specifically relates to a rigid multiway displacement anticollision guardrail which comprises upright columns which are arranged at the two sides of a bridge expansion joint, wherein a plurality of telescopic horizontal rods which are arranged along the bridge direction are uniformly arranged between the upright columns at the two sides along the vertical direction at intervals, so as to be suitable for longitudinal displacement between bridge bodies, the two ends of each telescopic horizontal rod are respectively articulated to the upright columns at the two sides by adopting a pin shaft and a hoop sleeve system so as to be suitable for transverse displacement between the bridge bodies, and in addition, every two telescopic horizontal rods are welded through a vertical connecting rod to form a rigid frame-type integrated anticollision structure. The rigid multiway displacement anticollision guardrail has the advantages of strong guardrail anticollision capability, strong deformation capability, convenience in maintenance and change and good landscape efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a rigid multi-directional displacement anti-collision guardrail. Background technique [0002] The structure of the bridge anti-collision barrier at the expansion joint is an important node in the design of the entire line of the anti-collision barrier. Here, the guardrail must have sufficient deformation capacity in the specified direction to meet the requirements of free expansion and deformation of the bridge, and must also have certain anti-collision impact capability. At present, the existing anti-collision guardrails at bridge expansion joints in China generally adopt hinged guardrails or nested guardrails. [0003] Such as figure 1 As shown, the hinged anti-collision guardrail adopts flexible hinge connection, which can adapt to the relative displacement in multiple directions between the expansion joints of the bridge. The disadvantage is that the stiffness ...
