Abstract

False floors are known, the load-bearing substructure of which exhibits vertically adjustable supports and grid-arrangement load-bearing bars which extend between the supports and comprise four-sided tubes. The floor panels are mounted, with their corners, on head plates of the supports and, with their border regions, on the grid-arrangement load-bearing bars. The connection of the grid-arrangement load-bearing bars on the supports is, however, unsatisfactory in static terms, this signifying that the loading capacity of the grid-arrangement load-bearing bars could be increased in the case of an improved connection. For this purpose, the grid-arrangement load-bearing bars comprising four-sided tubes are fixedly anchored, with their upper wall (17), on head plates (23) of the supports (10). Furthermore, the grid-arrangement load-bearing bars (15) are additionally mounted on a load-bearing ring (14) which is arranged vertically displaceably on each support (10). Finally, the grid-arrangement load-bearing bars (15) are connected, at least by the end borders (19) of their lower wall (18), in a positively locking manner to in each case one vertically adjustable sleeve (21) on the associated supports (10). The sleeve (21) may be mounted on the load-bearing ring (14) or may also form an integral part therewith. The head plates (23) are screwed on at the upper end of the vertically adjustable sleeves (21). <IMAGE>
