Title: Apparatus for bracing a tilt-up wall panel

Abstract: A tilt-up wall panel in raised position is braced with panel brace assemblies, and the panel brace assemblies are braced with a pair of knee brace assemblies for each panel brace assembly, to form a tripod-like structure which eliminates the need for the conventional lateral bracing of the panel brace assemblies. The knee brace assemblies are connected to the wall panel, and for that purpose, two knee brace assemblies extending laterally between a pair of spaced apart panel brace assemblies include a connector common to both and which is connected to the wall panel. A preferred connector includes a base plate adapted to be connected to the wall panel, and a pair of swivel means mounted on one side of the base plate and each forming part of one of the latter two knee brace assemblies.
