1. Screening floor in which sieve plates (1) of rubber or similar rubber-elastic material rest at least at two opposed lateral edges on a supporting frame (9) of steel or the like, said supporting frame having two flanks (10) converging in upward direction and delimiting with their upper edges an open slot (11), downwardly extending marginal strips (2) of the sieve plate being capable of being inserted into the slot (11) and being capable of being separated one from the other by means of a clamping ledge (12) to be forcibly driven between the marginal strips (2) of adjacent sieve plates (1) and the marginal strips (2) gripping under the edges of the flanks (10) in their separated position, characterized in that the marginal strips (2) of the sieve plates consist of metal, particularly of steel, and are firmly connected, particularly by vulcanization, with the sieve plates (1). |
