Adjustable support stand for pre-cast concrete wall forms

In a form assembly for manufacturing pre-cast concrete wall panels, said form assembly including I-beam frame members, the improvement comprising:

• an adjustable length support stand affixed to each one of a plurality of selected locations on said I-beam frame members, each said adjustable length support stand being operable to vertically position the corresponding said I-beam frame member at a selected height above a fixed reference plane, each said support stand including:
• a frame portion including a top plate and at least one gusset;
• a leg assembly supported within said frame portion and having a linearly extendable leg member for linear vertical movement relative to said frame portion, said at least one gusset guiding the linear movement of said leg member;
• and
• an actuator mechanism operably coupled to said leg assembly to affect selective linear movement of said leg member;
• and
• a clamping mechanism mounted to said frame portion to permit a detachable connection of said support stand to said I-beam frame member, said clamping mechanism including:
• a fixed clamp member attached to said frame portion and having a first hook portion for engaging a first beam flange of said pre-cast concrete wall panel form;
• a movable clamp member having a second hook portion formed substantially identically to said first hook portion and being oriented in opposition thereto for movement in a direction toward and away from said first hook member for engaging a second beam flange of said pre-cast concrete wall panel form;
• and
• fasteners interconnecting said fixed clamp member and said movable clamp member and being oriented parallel to said direction of movement of said movable clamp member to control through threading on said fasteners that provide a variable range of adjustment the positioning of said second hook portion relative to said first hook portion.
