The frame profile angles (6) project at the edge in a shoulder form (10) and have inwards bracket (11) on the vertical leg (6). The angle profile vertical and horizontal legs (8) join via a rounded transition (7) and the cover fastening irons (12) are resistance-welded to the brackets (11) and are supported by setdown bolts (14) between the irons and the baseplate (13) resistance-welded to the horizontal leg of the profile frame (5). The shaft wall has a rectangular steel profile (2) round its top edge topped by a rubber support (9) on which the frame (5) rests. An outside frame (3) welded to the steel profile (2) projects upward to terminate flush with the shaft cover (4) so as to surround the cover with narrow interval.
