Abstract (en)
[origin: EP0311886A2] At their ends, the frame parts (2) of the frame have connecting lugs (4, 5) which are arranged at a different height. During assembly of the frame, two frame parts (2) lie next to one another, the connecting lugs (4, 5) of which lie one above the other at a distance apart and are connected to one another by a screw connection (13). So that the frame parts (2) are connected to one another in a positive-locking manner, the frame is turned upside down and a liquid, pasty or granulated filling material is poured into a recess on the underside of the higher connecting lug (5). The filling material also flows into the bore (6) for the screw connection (13), which bore (6) is covered by a washer (16). After the filling material has solidified, the frame can be transported either in this state or in the dismantled state and put together again in the same manner. Due to this type of assembly, mechanical working of the frame parts 2 can be dispensed with. <IMAGE>
