         7 . Apparatus as set forth in  claim 1 , wherein the at least one support rib extends along a longitudinal extent of the support rib, wherein preferably the longitudinal extent extends along a straight line. 
     
     
         8 . Apparatus as set forth in  claim 7 , wherein the at least one support rib extends along its longitudinal extent starting from an outer edge of the plate surface. 
     
     
         9 . Apparatus as set forth in  claim 7 , wherein the at least one support rib extends along its longitudinal extent in the direction of a center point of the plate surface. 
     
     
         10 . Apparatus as set forth in  claim 9 , wherein the at least one support rib extends substantially radially in relation to the center point the plate surface. 
     
     
         11 . Apparatus as set forth in  claim 7 , wherein a height of the at least one support rib increases, preferably substantially linearly, in relation to the plate surface along the longitudinal extent of the support rib starting from the outer edge of the plate surface. 
     
     
         12 . Apparatus as set forth in  claim 11 , wherein the height of the at least one support rib increases along a straight line inclined in relation to the plate surface, wherein the straight line has an angle of inclination of between about 30° and 40°, preferably between about 30° and 35°, in relation to the plate surface. 
     
     
         13 . Apparatus as set forth in  claim 7 , wherein the at least one support rib extends along its longitudinal extent starting from at least one outer corner region, preferably from each outer corner region, of the plate surface. 
     
     
         14 . Apparatus as set forth in  claim 1 , wherein at least one centering collar is arranged on the plate surface for centering the apparatus on the pile end. 
     
     
         15 . Apparatus as set forth in  claim 14 , wherein the at least one centering collar is integral with the pressure distribution plate. 
     
     
         16 . Apparatus as set forth in  claim 14 , wherein the at least one centering collar is at least partially and preferably substantially completely in the form of a leg extending along a circular path. 
     
     
         17 . Apparatus as set forth in  claim 14 , wherein the at least one support rib adjoins the at least one centering collar. 
     
     
         18 . Apparatus as set forth in  claim 17 , wherein the at least one support rib is integral with the at least one centering collar. 
     
     
         19 . Apparatus as set forth in  claim 16 , wherein arranged on the plate surface is at least a first centering collar and a second centering collar arranged outside the circular path of the first centering collar, wherein preferably the first centering collar and the second centering collar are arranged concentrically on the plate surface. 
     
     
         20 . Apparatus as set forth in  claim 1 , wherein the pressure distribution plate is of a plate thickness of at most 35 mm, preferably between about 20 mm and 30 mm. 
     
     
         21 . Apparatus as set forth in  claim 1 , wherein the pressure distribution plate has at least one through hole, wherein preferably the at least one through hole is of a diameter of larger than 30 mm, preferably larger than 50 mm, particularly preferably about 60 mm.
