Mud sill

In combination:

• a scaffold assembly comprising a vertical member;
• a baseplate on the vertical member and having a downwardly facing surface;
• and
• a foot having a top surface and a bottom surface spaced in an axial direction,
• the foot having an opening in the top surface and a recess extending axially from the foot opening toward the bottom surface,
• the recess accepting the baseplate with the baseplate in an operative position;
• the downwardly facing surface bearing on the foot so as to cause a downward force produced by the vertical member to be applied to the foot and distributed by the foot through the bottom surface to an underlying support surface for the scaffold assembly,
• the bottom surface on the foot having a peripheral edge that bounds an area that is greater than an area bounded by a peripheral edge of the baseplate,
• wherein the top surface fully surrounds the foot opening and the foot opening and recess are configured so that:
• a) with the baseplate and foot in a first relative angular orientation with respect to a vertical axis, the baseplate can be directed through the foot opening into the recess;
• and b) with the baseplate within the recess and the baseplate and foot changed thereafter from the first relative angular orientation around the vertical axis to a second relative angular orientation a first downwardly facing surface on the foot confronts a first upwardly facing surface on the baseplate to prevent the baseplate from being translated vertically upwardly to be moved through the recess and foot opening to be separated from the foot,
• wherein the first downwardly and first upwardly facing surfaces are each substantially flat, parallel to each other, and oriented to be substantially orthogonal to the vertical axis.
