Abstract

The invention relates to the field of bridge construction, in particular to a bridge guardrail telescopic device. The bridge guardrail telescopic device comprises two guardrail plate assemblies, a damping frame assembly and a linkage rack assembly. Each guardrail plate assembly comprises a guardrail plate body, a driving anti-falling plate, multiple rebars and multiple positioning plates. The driving anti-falling plates are connected to the upper ends of the guardrail plate bodies in a sliding fit mode. The rebars are evenly welded to the outer ends of the guardrail plate bodies, and the positioning plates are welded to the outer ends of the rebars respectively. The two ends of the damping frame assembly are connected to the two guardrail plate bodies on the inner sides of the two guardrail plate assemblies respectively. When a bridge deforms or vibrates, the damping plate assembly in the device can achieve the effects of damping and buffering; when a gap exists in the bridge, the damping frame assembly can drive the driving anti-falling plates in the guardrail plate assemblies to slide inwards through the linkage rack assembly, thus, the gap generated by the bridge is blocked, andvehicles or pedestrians running on the bridge are prevented from falling off the bridge.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bridge guardrail telescopic device. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation such as walls, floors, roofs (except wooden roofs) into two independent parts, so that buildings or structures can be horizontally expanded along the long direction. In the prior art, the types of expansion joints mainly include the following types: 1) Galvanized thin steel plate expansion joints: on small and medium span fabricated simply supported beam bridges, when the deformation of the beam is within 20-40mm, it is often selecte...
