1. A readily transportable truss having a body which is internestable with at least two other similar trusses in a storage configuration thereof comprising:

  • a first upper elongated spar and a first lower elongated spar rigidly connected parallel to each other at first and second spaced locations by a first pair of elongated members extending perpendicular between said first upper elongated spar and said first lower elongated spar;

    a second upper elongated spar and a second lower elongated spar rigidly connected parallel to each other at first and second spaced locations by a second pair of elongated members extending perpendicular between said second upper elongated spar and said second lower elongated spar;

    at least two cross chords rigidly connecting said first upper and said second upper elongated spars in a parallel arrangement to define a plane and form a top portion of said truss, said cross chord laying substantially in said plane, and said truss defining a trapezium cross section having an open aspect opposite said top portion;

    a first tie-bar rigidly connected between the elongated member extending between said first upper spar and said first lower spar at said first location, and the elongated member extending between said second upper spar and said second lower spar at said first location, said first tie-bar spaced a selected distance from and parallel to said plane defined by said first and second upper spars;

    a second tie-bar rigidly connected between the elongated members extending between said first upper spar and said first lower spar at said second location, and the elongated member extending between said second upper spar and said second lower spar at said second location, said second tie-bar spaced said selected distance from and parallel to said plane defined by said first and second upper spars; and

    each of said first and second tie-bars having a lower surface which is approximately the same length as the distance between the outside surfaces of said first and second upper spars such that said truss can be internested with a similar truss by engagement of said top portions formed by said first and second upper spars with the lower surfaces of said first and second tie-bars.
