Abstract:
1. A quadrilateral structural truss having a tubular framework with opposing ends and that extends lengthwise along a main longitudinal axis, at least one of the opposing ends of the framework including two connector plate members welded to the framework between two corresponding longitudinal tubes, the two connector plate members being disposed in parallel and opposite to one another, each connector plate member being made of a monolithic piece having an outer side and a rear side, each connector plate member including: a corner beam section extending between the two corresponding longitudinal tubes, the corner beam section protruding from the rear side of the connector plate member, the corner beam section including two opposite ends, each having a corresponding first cutout configured and disposed to fit around an end of the corresponding longitudinal tubes; a main plate section extending perpendicularly inwards on a side of the corner beam section and in a direction that is substantially perpendicular to the longitudinal axis, the main plate section including at least one fastener hole to receive a mounting bolt, the main plate section and the corner beam section defining together a planar outer abutment plate surface; and a lip projecting at right angle from the main plate section on the rear side of the connector plate member, the lip extending substantially parallel to the corner beam section.
