Claim 1:
2. The structural framework of claim 1, further comprising:
(c) a second support beam, the second beam having ends forming a channel shape with an interior, the ends having first and second inwardly facing flanges, and the interior having a second longitudinal centerline;
(d) a second support bracket connectable to the second support beam, the second support bracket comprising:
(i) a first flange of the second support bracket,
(ii) a second flange of the second support bracket, the first flange of the second support bracket meeting the second flange of the second support bracket at an apex and forming an angle with the second flange of the second support bracket,
(iii) a support section connected to the first flange of the second support bracket, wherein the second support bracket has locked and unlocked states relative to the second support beam, and the second support bracket changes from an unlocked state to a locked state relative to the second support bracket by rotation in a first rotational direction about an axis which is generally parallel to the second longitudinal axis and creating a locking force between the second support bracket and the second support beam which increases as the amount of weight supported by the second support bracket is increased, and the second support bracket changes from a locked state to an unlocked state relative to the second support bracket by rotation in a second rotational direction about the axis which is generally parallel to the second longitudinal axis; and
(iv) a second clamping section releasably connectable to the second support bracket and when connected to the second support bracket maintaining the second support bracket in the locked state relative to the second support beam by squeezing the second support beam between the second support bracket and the second clamping section.
