Abstract
A door frame fixturing and bracing apparatus for fixturing and bracing a metallic door frame having two opposed jambs and a connecting header above a floor and typically between masonry walls. The apparatus includes a single fixturing frame having an upper member, a lower member, and at least one brace member disposed between a pair of opposed side members, the members being connected together to form an integral rectangular fixturing frame generally conforming to at least a width wise extending interior portion of the metallic door frame between its jambs. Legs are pivotally connected to the side members for swinging movement which is lateral to the plane of the door frame. A fastening means for temporarily securing the fixturing frame to the door frame includes a screw means for engaging apertures in the door jambs. An open ended clamp pivotably mounted to each of the side members provides a means for adjusting a length of each of the legs between the side members and the floor to locate the legs at a required inclination with respect to the floor. A flat support base is pivotably attached to a bottom end of each of the legs.
