ABSTRACT OF THE DISCLOSURE A frame for forming coverings for ground openings and method of assembling such frame are disclosed. Frame parts for assembling the frame are provided at their ends with connecting lugs, which are arranged at different levels. On fitting the frame, the two frame parts are juxtaposed, their connecting lugs are arranged in spaced superimposed manner and are interconnected by screw couplings. For positively interconnecting the frame parts, the frame is turned upside down, and a liquid, pasty or granular filling material is filled into a bore on the underside of the upper connecting lug. The filling material also flows into the bore of the screw coupling, which is covered by a washer. Following the solidification of the filling material, the frame can either be transported in this state or in a disassembled state and can be then reassembled in the same way.
