Guardrail device for municipal bridge

Abstract

The invention discloses a guardrail device for a municipal bridge. The guardrail device for the municipal bridge is characterized by comprising supporting uprights positioned at the two ends; concretepiles integrally connected with the bridge are arranged at the lower ends of the supporting uprights; an upwarp elastic iron wire is arranged between the supporting uprights; connecting columns, which penetrate out of one sides of the concrete piles from the supporting uprights, are fixedly connected to middle parts, inserted into the supporting uprights, of the upwarp elastic iron wire; extrusion springs sleeve the connecting columns; propping discs, whose diameters are larger than the diameters of the connecting columns and which prop against the lower ends of the extrusion springs, are arranged at the bottoms of the connecting columns; cover sleeves sleeve the extrusion springs; the diameters of openings at the upper ends of the cover sleeves are less than those of the propping discs and larger than those of the connecting columns; and hinging columns transversely inserted into the concrete piles to rotate are fixedly connected to the lower ends of the cover sleeves. According to the guardrail device for the municipal bridge, hard contact between the guardrail device and a force applying object is reduced to obviously improve the buffering performance of the guardrail device.

Description

technical field [0001] The invention relates to a guardrail device, more specifically it relates to a guardrail device of a municipal bridge.
