Abstract
A framework of structural members having the appearance of a truss, for supporting concrete forms that mold the floors of buildings, including upper and lower beams joined by vertical upper column members and diagonal members, lower column members that support each upper column member on the floor, and screw jacks at the bottoms of the lower column members to permit fine height adjustments. The fact that each upper column member is separately supported by an adjustable device that assures proper vertical positioning, means that there are minimal bending stresses in the upper and lower beams during the heavy loading which occurs when supporting poured concrete, so that the structural members can be constructed of a material of high strength but low rigidity such as aluminum.
