metal fence post

Abstract

The invention relates to a metal fence column, which is used for installing a fence mesh sheet with several mesh holes. The fence column includes: a first body, which is hollow column-shaped and extends along a vertical direction. The first body has a rear side wall; Two bodies, which are installed on the rear side wall of the first body through threaded fasteners; the first body is formed by bending a steel plate extending vertically, the steel plate has a first free end and a second free end, and the steel plate is in the After bending, the two free ends are stacked and fall on the rear side wall of the first body, the two free ends are riveted and fixed by a plurality of rivets, and the front end of the threaded fastener is fixedly connected to the rivets. By riveting the two free ends on the first body with rivets, the first body does not need to be welded. Moreover, since the front end of the threaded fastener is screwed into the rivet, the front end of the threaded fastener will not be exposed after the fence post is installed, thereby increasing the anti-destructive property of the fence system.

Description

technical field [0001] The invention relates to a metal fence post. Background technique [0002] The use of metal fence systems to protect the perimeter of buildings, important places, etc. has become popular. A common metal fence system includes a number of fence posts fixed on the ground by pouring or fasteners and two parts of a fence mesh whose ends on both sides are fixed between two adjacent fence posts. This type of metal fence system is easy to install and construct, and is currently widely used. [0003] As an important part of the fence system-the metal fence column is mainly divided into the following two types: the first type, such as the metal fence column disclosed in US Patent No. Several hooks are formed at the left and right ends of the side, and the fence mesh is clamped and fixed between two adjacent columns through these hooks; for another structure, see patent EP1564351A1, WO / 2013 / 083044, the fence of this type of structure The columns are composed o...

AI Technical Summary

Problems solved by technology

Although the second type of fence post relies on the recess on the side wall of the fence post to accommodate one end of the fastener, it is still easily damaged.

In addition, since the fasteners have to pass through the opposite side walls of the fence posts, the length of the fasteners must be long enough, thereby increasing the cost of use

Among the above two kinds of fence posts, the main part of the post (that is, the first main body) is divided into two types, one is a square opening structure, and the strength of the column of this mechanism is relatively weak; the other is a closed structure, this A welding process needs to be added during the manufacture of the column body, and the manufacturing cost is high
