Abstract: 1. An anchoring system for fixing plates and/or tiles to a support structure, comprising at least two anchoring elements consisting of laminar bodies (1), a portion of said bodies being inserted into straight undercut dead notches (3) made in said plates and/or files (2), characterized in that the laminar bodies (1) are so shaped that when inserted in the notches (3), they lean on the corresponding edge (5) of the notch (3) or in proximity thereof with an obtuse angle, formed by the intersection of the inner plane (23) of the notch (3) with the plane of the plate and/or tile (2), thus acting as a support lever fulcrum causing the corresponding portions of the laminar body (1) inserted into the notches (3) to press strongly on the corresponding outer support plane (24) consequently providing a strong and sturdy constraint fixing the plate and/or tile (2) to the support structure (10). 2. The anchoring system according to claim 1 characterized in that said laminar bodies (1) are made of metal and/or other highly resistant material. 3. The anchoring system according to claims 1 and 2 characterized in that the laminar bodies (1) may have a bent (18) or straight (20) profile and/or a thickened portion (19). 4. The anchoring system according to claims 1 to 3 characterized in that the laminar bodies (1) may be provided with holes (6) and/or slots (11). 5. The anchoring system according to claims 1 to 4 characterized in that the straight undercut notches (3) are symmetrically mirror, radially or orthogonally arranged on the plate plane. 6. The anchoring system according to claims 1 to 5 characterized in that the portions of the laminar bodies (1) protruding from the straight undercut notches (3), are so shaped that they may be joined or arranged parallel, transversally or slantly to each other. 7. The anchoring system according to claim 6 characterized in that the portions of the laminar bodies (1) protruding from the straight undercut notches (3), are securely joined through bolts (8) and nuts (7) or by joints or welding, said welding being carried out by spot welding and the like. 8. The anchoring system according to claims 1 to 5 characterized in that the portions of laminar bodies (1) protruding from the straight undercut notches (3) are so shaped that between the laminar bodies (1) a body (9) of metal and/or other material is interposed, to which said laminar bodies (1) are securely fixed through bolts (8) or other means such as joints or welding. 9. The anchoring system according to claims 1 to 8 characterized in that the straight undercut notches (3) are obtained by simple disc grinding (4) of the plate and/or tile (2). 10. The anchoring system according to claims 1 to 9 characterized in that each straight undercut notch, (3) has a variable length and may receive one or more juxtaposed laminar bodies (1) precisely arranged at the anchoring point. 11. The anchoring system according to claims 1 to 10 characterized in that the plates and/or tiles (2) are provided with rear net like webs (22) previously applied with an adhesive on the rear side of the plate to avoid its breaking up. 12. The anchoring system according to claim 11 characterized in that between plate and/or tile (2) and the net like body (22) a cable of stainless steel (16) or other flexible material may be inserted, the ends of said cable being fixed to the laminar bodies (1) or joining body (9), said cable in case of breaking up of the plate and/or tile (2) holding the broken up plate preventing it falling down to the ground. 13. A method of anchoring plates and/or tiles to a support structure, comprising the steps of: making straight undercut dead notches (3) in the rear surface of said plates and/or tiles (2); providing at least two anchoring elements consisting of laminar bodies (1) according to one or more of claims 1-10; inserting a portion of said laminar bodies (1) into said notches (3); and fixing the anchoring elements to the support structure. 14. The method of claim 13, wherein the plates and/or tiles (2) are provided with rear net like webs (22) previously applied with an adhesive on the rear side of the plate to avoid its breaking up. 15. The method of claim 14, wherein between plate and/or tile (2) and the net like body (22) a cable of stainless steel (16) or other flexible material may be inserted, the ends of said cable being fixed to the laminar bodies (1) or joining body (9); said cable in case of breaking up of the plate and/or tile (2) holding the broken up plate preventing it falling down to the ground.
