ABSTRACT:
A panel support column for supporting sheet rock panels in an overhead position during the fixed mounting of the sheet rock panels to a ceiling. The panel support column is comprised of a broad flat bearing plate, rotatably attached to a circular cross section support rod, a support barrel having a cavity which closely accepts the support rod for reciprocative movement, an upper and a lower retaining clamp, a compression spring mounted around the juncture of the support rod and support barrel, and an non-slip end cup on the lower end of the support barrel. The support rod has a plurality of height adjusting holes to which the upper clamp can be attached so as to allow adjustment of the height of the panel support column to accommodate ceilings of different heights. In operation, the support column is adjusted to a length greater than the floor-to-ceiling height so that the support rod can be manually urged into the support barrel, the support column then positioned under the panel to be supported, thereafter allowing the compression spring to urge the support rod out of the support barrel to support the panel in place.
