ABSTRACT:
A ramp structure which may be constructed quickly to provide temporary or permanent access to all individuals between two areas of different elevation. A truss design allows long spans to form a bridge without the need for intermediate supports and related support foundations. A truss cross-connector is firmly wedged in place between two trusses and allows the quick, solid joining of two trusses without fasteners to form a strong and stable assembly to serve as ramps, bridges, elevated walkways, etc. The truss cross-connector has resistance to bending and supports the edge of a surface panel and provides a retaining pocket for the surface panel. The truss cross-connector firmly supports the trusses in an upright position when the trusses are used as railings. Surfacing panels placed between the truss cross-connectors provide a high quality, long lasting surface which is quickly installed for temporary or permanent installations, but which can be easily removed for reuse. The truss cross-connector also prevents casual removal of a closely fitting surface panel. A special tool is included in the system for easy disassembly of light trusses of this design without damage to the components. The design of a truss/panel ramp system can be easily disassembled and reused for temporary or permanent installations and meets Americans with Disabilities Act guidelines.
