Abstract

The invention provides a protective fence. The protective fence comprises a plurality of vertical columns which are arrayed side by side at intervals, and transverse rods arranged on the vertical columns, wherein a connecting part is arranged at one side of the top of each vertical column; each connecting part comprises two horizontal sections which horizontally extend outward from the corresponding vertical column and are arranged at interval, and a vertical section connected between the two horizontal sections; the middle part of each vertical section is inward concave to from an annular groove; two through holes are formed in each annular groove; the transverse rods are fixed to the connecting parts of all the vertical columns through U-shaped screws; the hole diameter of the through holes in the grooves is less than the screw diameter of the U-shaped screws; two thread ends of each U-shaped screw penetrate into the through holes of the corresponding groove; the transverse rods penetrate into the U-shaped screws and are fixed. According to the protective fence provided by the invention, the transverse rods are mounted on the connecting parts of the vertical columns through the U-shaped screws; the protective fence is convenient and rapid to assemble on site, and is conveniently assembled on a narrow road when a vehicle drives; the protective fence is firm and stable to assemble and is not easy to loose.

Description

technical field [0001] The invention relates to a railing, in particular to a protective railing. Background technique [0002] At present, guardrails are often used on municipal roads to isolate the driving direction between motor vehicle lanes and play the role of central isolation; or in densely populated areas such as schools and stations, in order to ensure the safety of pedestrians and the smooth running of vehicles, set up Guardrails for motor vehicle lanes and non-motor vehicle lanes; or enclosing green belts, etc. The existing guardrails are made of plastic steel, and there are many parts. They are connected by electric welding or nuts. The installation is complicated and time-consuming, and it is easy to loosen during use and cause safety hazards. It needs to be improved. Contents of the invention [0003] The invention proposes a protective fence, which solves the problems of complicated assembly and the like in the prior art. [0004] Technical scheme of the ...
