Description

Screw type fence post assembly {Spiral type fence post assembly}

The present invention relates to a fence post assembly for fixing a wire mesh, and more specifically, to a screw-type fence post assembly that can fix a wire mesh to the ground without using a concrete base.

Figure 1 is a diagram for explaining that a fence pillar is fixed to a concrete base embedded in the ground, and Figure 2 is a diagram for explaining that an undercut phenomenon occurs between the pillar body and the anchor flange of Figure 1.

As shown, a conventional fence pillar is intended to support a wire mesh (not shown), and includes a pipe-shaped pillar body (1), an anchor flange (2) fixed to an anchor bolt fixed to the ground, and an anchor flange ( It includes a fusion end (3) that fuses the upper surface of 2) and the circumference of the pillar body (1). At this time, the fusion end (3) is in close contact with the lower end surface of the column body (1) to the upper surface of the anchor flange (2) in the vertical direction, and the welding rod is connected to the corner between the column body (1) and the anchor flange (2). It is formed naturally during the welding process along the perimeter.

For these fence pillars, the anchor bolt and anchor flange insertion holes protruding from the upper side of the concrete pillar (C) embedded in the ground at regular intervals are inserted, and the anchor bolts protruding from the upper part of the anchor flange (2) are then inserted with nuts (N). By fastening, it is firmly fixed to the concrete base (C).

However, in places where it is not easy to install fence pillars, such as mountain slopes or soft ground, it was not easy to move or bury the concrete pillar (C), so there were many difficulties in installing fence pillars. .

In addition, since the welding of the column body (1) and the anchor flange (2) is carried out by moving the welding rod along the corners of the column body (1) and the anchor flange (2), the holding angle or the moving rod of the welding rod may be changed due to unskilled use. When the welding speed is not constant or the welding current is high, an undercut phenomenon occurs in which the connection portion of the column body 1 and the anchor flange 2 is dented, as shown in FIG. 2.

This undercut phenomenon weakened the rigidity between the column body (1) and the anchor flange (2), and also caused dew or rainwater to accumulate in the recessed groove formed by the undercut, causing corrosion to proceed quickly, and furthermore, welding. The high heat generated during the process caused changes in physical properties and caused corrosion to progress quickly, ultimately weakening the sturdiness of the fence pillar.

The present invention was created to solve the above problems, and its purpose is to provide a screw-type fence post assembly that can be easily installed by eliminating the need to bury heavy concrete pillars in the ground.
