Problems solved by technology

Obviously, this kind of screw connection is difficult to achieve the effect specified in the standard.
In addition, in order to strengthen the strength of the screw connection between the two short columns, it is necessary to weld a large flange and reinforcement on the column, which will undoubtedly increase the cost; at the same time, in order to prevent theft, the connecting screws must use special screws, which increases the cost. The cost

Abstract

The invention provides an upright post for an expressway fence. The upright post comprises an upper upright post and a lower upright post, which are in threaded connection with each other; and a fixing nut is arranged at the junction of the upper upright post and the lower upright post and arranged at the periphery of the upper upright post in a sleeving manner. The upper upright post and the lower upright post are in threaded connection with each other, the connection way is simple and quick, the replacement is convenient and the maintenance is time-saving and labor-saving; and in addition, the intensity of the overall upright post is ensured, the effect of protecting the safety of vehicles is obtained, and burglary-resisting protection to the upright post is enhanced by adopting the nut for fixing in adverse directions.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a post for expressway guardrails. Background technique [0002] In order to prevent traffic accidents and reduce the risk of accidents, safety guardrails are installed on both sides of all expressways, which act as barriers and guarantees. The highway guardrail is composed of guardrails, columns, anti-blocking blocks and several connecting plates. The installation method of the columns is generally to bury the columns directly into the ground concrete to a depth of more than 1.65m, and the upper end of the column is exposed to the ground for about 1m for installation and fixing. guardrail. When the column is damaged by the impact of the car, it is necessary to replace the column to repair it in time. Since the column is deeply buried in the concrete, to replace the column, it is necessary to dig out the entire concrete block and then refill it with a new column. Concr...
