         3 . The support according to  claim 2 , wherein said plane portion further comprises rectilinear cut or notch defining an additional, detachable circular segment on said plane portion. 
     
     
         4 . The support according to  claim 3 , wherein said notch of said plane portion is orthogonal to said rectilinear edge. 
     
     
         5 . The support according to  claim 3 , wherein said notch of said plane portion is tangential or adjacent to said tubular raised portion. 
     
     
         6 . The support according to  claim 1 , wherein said plane portion is circular in shape, with two circular segments missing, and wherein said two circular segments are defined by respective chords which are orthogonal to each other. 
     
     
         7 . The support according to  claim 3 , wherein said plane portion comprises one or more openings or seats for the engagement or coupling of fixing brackets designed to constrain vertical elements or riser panels for making steps. 
     
     
         8 . The support according to  claim 7 , wherein said openings or seats are defined in said plane portion in a diametrically opposite position with respect to said rectilinear edge and to said notch, if present. 
     
     
         9 . The support according to  claims 7 , wherein said plane portion comprises a recess defined in said at least one rectilinear edge. 
     
     
         10 . The support for raised floors according to  claim 1 , further comprising a lower bracket configured to constrain a riser or a vertical element coupled to said base (B). 
     
     
         11 . The support for raised floors according to  claim 10 , wherein said lower bracket comprises a planar portion configured to be rested on the ground that is under said planar portion of said base, a first end shaped with tabs or projections configured to engage a lower edge of said riser, a second opposite end shaped with a tooth, a raised part, or an outer tab configured to be inserted in a corresponding opening or seat defined in said plane portion of said base. 
     
     
         12 . The support according to  claim 11 , wherein said tabs or projections of said lower bracket are obtained by bending parts of said first end towards a same side, said tabs or projections being defined to be oriented upwards and shaped as to form a U-shaped seat (S 4 ) configured to elastically retain said lower edge of said riser. 
     
     
         13 . The support according to  claim 12 , wherein said tooth, said raised part, or said outer tab is bent in a shape of a C on a same side as said tabs or projections so as to be oriented upwards and coupled from below in said corresponding opening or seat created in said planar portion of said base. 
     
     
         14 . The support according to  claim 1 , wherein said base comprises said raised portion extending upwards from said plane portion and configured to be connected to other parts of said support for raised floors. 
     
     
         15 . The support according to  claim 1 , further comprising:
 an upper head on which floor panels can be rested, the upper head being configured to be directly or indirectly constrained to said base the upper head comprising a planar upper surface on which said floor panels can be directly or indirectly rested, and one or more partitions extending upwards from said upper surface; and   an upper bracket for constraining an upper edge of a riser to said upper head,   wherein said upper bracket comprises a flat part configured to be rested on said upper surface of said head, a first end shaped with first for engagement of the upper edge of the riser (A), and wherein said flat part of said upper bracket comprises one or more holes or seats in which said partitions of said head can be inserted.   
     
     
         16 . The support according to  claim 15 , wherein said first tabs of said upper bracket are obtained by bending parts of said first end towards a same side, said first tabs being intended to be directed downwards and configured so as to form a seat configured to elastically retain said upper edge of a riser panel. 
     
     
         17 . The support according to  claim 15 , wherein said upper bracket comprises, on said first end, a further tab bent on an opposite side with respect to said first tabs and designed to come into contact with an edge of an upper floor panel. 
     
     
         18 . The support according to  claim 17 , wherein said further tab is aligned with one of said first tabs. 
     
     
         19 .
