Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1As shown, a guardrail device for a municipal bridge includes a concrete pile 1 integrally connected with the bridge and support columns 2 inserted and fixed in the concrete pile 1 and located at both ends of the concrete pile 1 respectively. The lower end of the side of the concrete pile 1 facing the bridge is provided with a rounded corner 11 , thereby reducing the rigid contact between the collision shell and the concrete pile 1 while avoiding dust accumulation. An arcuate surface 23 is arranged on the side of the supporting column 2 facing the bridge, and the upper curved elastic iron wire 4 and the middle curved elastic wire 4 distributed along the arc of the arcuate surface 23 are sequentially arranged between the two supporting columns 2 from top to bottom. Elastic iron wire 41 and downward curved elastic iron wire 42. It should...

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. Background technique [0002] Bridge guardrail refers to the guardrail set on the bridge. Its main function is to prevent out-of-control vehicles from getting out of the bridge, and has the function of preventing vehicles from breaking through, passing under, and overturning the bridge and beautifying the bridge building. [0003] The Chinese patent with the publication number CN105951593A discloses a bridge guardrail structure. The bridge guardrail structure includes two uprights, the uprights are embedded with fluorescent strips, and a top plate is arranged laterally near the top of the uprights, and the top plate is fixed On the column, a reinforcement plate is provided between the lower surface of the top plate and the bottom of the column, both ends of the reinforcement plate are fixedly connected to the column, and steel nails ar...
