[002] Prior barrier systems consisted of fences, concrete walls, and the like, which suffered from deficiencies such as penetrability, cost, and long construction periods required.

SUMMARY OF THE INVENTION

[003] The present invention can be constructed and installed at lower cost and within shorter time periods than prior barrier systems and comprises in one aspect a barrier system comprising at least one module which includes a frame, a concrete foundation, a frame attached to the concrete foundation and supporting a non-vertical front side plate and a vertical rear side plate on a frame so that the front side plate and rear side plate meet at the top of the frame and are spread apart from each other at the bottom, slotted connectors on the front side and connectors on the rear side, the module adapted to be joined to an adjacent module either at the same elevation or a different elevation.

[004] The barrier modules can be prefabricated in factories and shipped in one piece for field erection for expedient, rapid, and safer installation, made possible by the unique and adjustable end connectors which insures that each prefabricated module may be connected with each other as a true match at any variation in elevation in ground topography.

[005] In some embodiments the modules include motion detection systems to detect any attempts at intrusion, vandalism, or attack, including underground tunneling attempts.

[006] The rear plate is preferably a TG solid aluminum plate which is resistant to armor piercing bullets, is impervious to weather damage, and requires little or no maintenance.

[007] In some embodiments, lightening arrestors are included at the top and connected to lightning ground rods. Barbed wire or other defensive devices are also optional ,

[008] Solar film elements can be applied to either or both sides of the module and collection wiring and terminal conversion to solar energy to transfer to local utilities is possible, which is an advantage of the modules and barrier wail of the invention since the modules include large flat areas suitable for solar energy systems,

[009] In some embodiments the slotted connectors include two holes for receiving bolts, one of which is distal and the other proximal, wherein the distal holes are aligned with an area within the frame and the proximal holes are forward of the front plate. The slotted connectors are arranged on the front side plate and vary in width, with the widest slotted connector nearest to the bottom of the module and above the concrete foundation, and the narrowest slotted connector nearest the top of the module. The slotted connectors have an open side and a closed side, with the open side being open toward the front of the module and the closed side fastened to the member of the frame supporting the rear side. The slotted connectors are designed to receive matching extenders within the slots. The extenders are used to compensate for differences in width when two modules at different elevations are to be joined together, in which case a proximal hole of a wider slotted connector is bolted to an extender in a slot of a less wide slotted connector, thereby allowing easy and efficient connection between modules at different elevations from each other.

[0010] Two modules can be joined to each other with bolts through the connectors on the rear side and toggle bolts through the proximal holes in the slotted connectors which are aligned with the area within the frame.

[001 1] Modules at different elevations from each other can be joined together so that the top holes of one module are adjacent to the second, third, fourth, or fifth from top holes of a second module and the holes are connected with bolts when the holes are aligned.

[0012] Extender bars having forked ends can be located within the slots of the slotted connectors.

[0013] In the method aspect of the invention, a barrier wall system is constructed by placing prefabricated modules adjacent to one another and bolting them together. The modules can be at varying elevations with respect to the ground and due to the unique connector system the variations in elevation can be accommodated. BRIEF DESCRIPTION OF THE DRAWINGS
