ABSTRACT:
The screening or security fence structure of this invention includes a plurality of spaced I-beam vertical support posts with standardized fence panels placed between them. While each fence panel is securely mounted to the I-beam posts, it is also firmly and contiguously connected through the posts to adjacent panels, so that the entire fence structure is linked together. By this configuration, an impact force on one of the fence panels is distributed along the fence. Additionally, the vertical side members of each fence panel frame abut the inside surfaces of the I-beam posts. If a fence panel is struck by a moving vehicle, the vertical frame member will jam against the I-beam flanges thus preventing the fence panel from breaking away and causing a safety hazard.
Additionally, the fence fabric mounting hardware is secured within the I-beam channels thus reducing possible vandalism. In an alternative embodiment, a cable may be run the length of the fence inside the horizontal fence panel frame members. The cable prevents the panels from being removed and also further serves to distribute any impact force along the fence. Panels may be stacked vertically to achieve greater height.
