Fig. 2) (according to Fig. 1 the floating elements 2 and 3 and according to Fig. 2 the floating elements 2 consist of two lateral faces 4 and 5 with two vertical projections 6 on one (4) of then and with one vertical projection 6 on the other (5), according to Fig. 3 they consist of two lateral faces 7 and 8 with two vertical cavities 9 in one (7) of them and another vertical cavity 9 on the other (8), corresponding to vertical the projections 6, of top and bottom faces 10 and 11). Each vertical projection 6 is configured with a constricted portion 13, extending to the periphery portion 14, of corresponding lateral face 4 (5) thus forming a supporting surface 15, and each vertical cavity 9 is configured with a constricted portion 16, extending to an expanded to the center potion 17 of the corresponding floating element 2 (3) in the portion of the corresponding lateral face 7 (8) thus forming a supported surface 18, wherein one of each floating element 2 and 3 lateral faces 5 comprising a vertical projection 6 is provided with at least a projection 19 surrounding the corresponding fastening element 1 from at least above and placed on one side of said vertical projection 6 and with at least a projection 20 supporting the corresponding fastening element 1 and placed on the other side of said vertical projection 6, the projections being portions of corresponding fastening elements 1 mating parts, and the other of each floating element 2 and 3 lateral faces 4 comprising a vertical projection 6 is provided with flanges 21 and 22 supporting each fastening element 1, the flanges being portions of the corresponding fastening elements 1 mating parts, wherein said lateral face 4 of at least one floating element 2 contains an additional surrounding projection 23 placed between the vertical projections 6 and provided for linking the floating elements 2 and 3 each having the lateral faces 4 and 7 with two vertical projections 6 and two vertical cavities 9, correspondingly, being placed either with a displacement (in a brickwork manner, not shown) or for linking the floating elements 2 and 3 with each other, having one floating element 2 having the lateral faces 4 and 7 with two lateral projections 6 and two vertical cavities 9, correspondingly, and another floating element 3 having the lateral faces 4 and 7 with one vertical projection 6 and one vertical cavity 9 on each face (rf. Fig. 2). Each floating element 2 and 3 third lateral face 7 comprising at least one vertical cavity 9 may have at least some abutments 24 and 25 (limit stops) provided on both sides of each vertical cavity 9 for corresponding fastening element 1, and both, each vertical projection 6 and each vertical cavity 9 may have a dovetail cross section 26 with rounded corners 27. Besides the third and the fourth lateral faces 7 and 8, having vertical cavities 9, may have additional cavities 28 on both sides of each one. Whereby, the height h 1 of the lateral faces 4 and 5 portions from the top face 10 to the vertical projections 6 supporting surfaces 15 may be made equal to the height h2 of the lateral faces 7 and 8 portions from the top face 10 to the vertical cavities 9 supported surfaces 18, thus providing uniform vertical loads bearing over the top faces 10 of the floating elements 2 and 3.
