Problems solved by technology

In practice, welded mesh fences present problems.
For example, in a typical installation, the fence posts are installed about 8 feet apart, but the spacing may be very irregular.
In welded mesh fencing, however, stretching the width of the panel is not possible Further, the hardware typically used to join panels leaves nuts or other parts that are vulnerable to attack on the outside of the fence, reducing the security of the fence.

Embodiment Construction

[0015]Referring now to FIG. 1 an example of a wire-mesh fence panel 100 is seen comprising substantially parallel rail-wires 102, each having a first end 102a and a second end 102b. Substantially parallel cross-wires 104 are welded across rail-wires 102 at substantially regular intervals. At each end of the panel 100 a connection strip is welded across the ends of the wires 102. As seen in detail in FIGS. 1A-1D, picket-wire-side connection strip 106 is welded on the picket-wire side 108 of panel 100, and opposite-side connection strip 110 is welded across the ends of the wires 102 on the side opposite the picket-wire side 108 of panel 100

[0016]Referring now to the example of FIG. 2, each connection strip 106 and 110 has an outside edge 112 that is spaced from the end of the wires to which the strip is welded. As the two panels 100a and 100b are moved together, the ends of the rail-wires face each other; and, if the spacing is regular enough, as seen in the top-view of FIG. 3, this a...

Abstract

A wire-mesh security fence panel and security fence is provided. In at least on example the fence panel includes: a first set of substantially parallel wires, each wire having a first and a second end; a second set of substantially parallel wires, the second set of wires being welded across the first set on one picket-wire side of the first set; a cross-wire-side connection strip welded across the first end of the first set on the picket-wire side of the first set; and an opposite side connection strip welded across the second end of the first set on the opposite side of the picket-wire side. In one such example each connection strip has an outside edge and each outside edge is equally spaced from the end of the wires to which the strip is welded.

Description

BACKGROUND[0001]In the field of security fences, “cut resistance” and “climb resistance” has led to the use of welded mesh fence. Such fences are made by arranging multiple horizontal lines of wire—spaced apart a small distance—and welding vertical cross wires to the horizontal lines. The result is a mesh. Typical mesh used in security fences is so called “3-5-8” (meaning that the horizontal lines are about 3 inches apart, the cross wires are 0.5 inches, and the wire is 8 gauge). Other dimensions and mesh patterns are known or will occur to those of skill in the art. The wires are welded into a mesh on a variety of welding systems (for example, automatic resistance-mesh welders, such as those available from Entwicklungs- and Verwertungs-Gesellschaft m.b.H. (a.k.a. “EVG”) and Clifford / Ideal Welding Systems). Continuous wire welders and jig welders are used to perform the welding. To prevent the panels from warping, tension is placed on the wires during the welding process. The ends o...
