Floor, according to claim 2, characterized in that the distance between the sleepers doesn't exceed 100 sm., and the distance between reach-through holes in the sleepers doesn't exceed 150 sm. 3. Floor, according to claim 1 or 2, characterized in that the inner surface of hollow support, at least, at the part of height is made in form of truncated pyramid or prism preferably hexahedral. 4. Floor, according to any of claims 1-3, characterized in that the height of cone-shaped part of the end of the hollow support is, at least, equal to the distance between the adjacent turns of outer thread of support. 5. Floor, according to any of claims 1-4, characterized in that the ratio of minimal width of the wall of hollow support to the outer diameter is 0.15-0.9, and the ratio of the outer diameter to the height thereof is 1/2 -1/10. 6. Floor, according to any of claims 1-5, characterized in that at the outer diameter of the end of hollow support, equal to the inner diameter of the outer thread, its outer surface is plane or convex with radius, inverted to the base of the floor. 7. Floor, according to any of claims 1-6, characterized in that planking comprises at least, one layer and made in form of panel. 8. Floor according to claim 7, characterized in that the planking id made of plywood, or wood chips, or wood-fibre, or sawdust-shavings material or cement-shaving, or plaster-fibre materials. 9. Floor according to any of claims 7 or 8, characterized in that the panel is provided, from the side inverted to the base, with heater and sound-absorbing material. 10. Floor according to any of claims 7 or 8, characterized in that it is provided with ventilation system or heating system, installed under the planking. 11. Floor according to any of claims 7 or 8, characterized in that it is provided with hydraulic insulating material, placed under the planking surface. 12. Floor according to any of claims 1 or 11, characterized in that, the hollow support is made by height, providing the accommodation of communications under the planking. 13. Floor, according to any of claims 1-12, characterized in that the hollow support is made of polymeric material. 14. A set of elements for leveling and/or installing of floor planking on the given level relatively to the base of it, comprising N - quantity of sleepers with reach-through hole, fixing-supporting elements, made in form of hollow support with outer thread and end closed from one side for fixing of hollow support to the base of the floor, characterized in that the set can be provided with plugs and/or fixing elements, each reach-through hole in sleeper is made with inner thread or with the possibility of installing the plug inside of it, having inner thread with flange on one side, wall of hollow support is made with alternative thickness by height and/or perimeter, end of support from the cavity side has cone-shaped surface, wherein outer diameter of the end is equal to the inner diameter of outer thread of support or exceeds it with forming of flange , with height of at least, half of distance between adjacent turns of the thread, the end being optionally made with at least one central hole for passing of fixing element. 15. Set of elements according to claim 14, characterized in that the distance between reach-through hole in sleepers doesn't exceed 150 sm. 16. Set of elements according to claim 14 or 15, characterized in that the inner surface of hollow support, at least, on the part of the height is made in form of truncated pyramid or prism preferably hexahedral. 17. Set of elements according to any of claims 14-16, characterized in that the height of cone-shaped part of hollow support end is at least, equal to the distance between turns of the outer thread. 18. Set of elements according to any of claims 14-17, characterized in that the ratio of minimal width of hollow wall to the outer diameter thereof is 0.15-0.9, and the ratio of outer diameter of support to the height is 1/2 -1/10. 19. Set of elements according to claims 14-18, characterized in that at the outer diameter of the end of hollow element, equal to the inner diameter of the outer thread thereof, outer surface of end is plane or convex with radius, inverted to the floor base. 20. Fixing-supporting element for leveling and/or installing of filler structure on the given distance relatively to the base of it, made in form of hollow support with outer thread to be screwed into the filler structure and having end closed from one side of it to the base of the floor, characterized in that the wall of hollow support is made with alternative thickness by height and/or perimeter, end of support from the cavity side has cone-shaped surface, wherein outer diameter of the end is equal to the inner diameter of outer thread or exceeds it with forming of flange with height of at least, half of distance between adjacent turns of the thread, the end being optionally made with at least one central hole for passing of fixing element. 21. Fixing-supporting element according to claim 20, characterized in that the inner surface of hollow support at least, on the part of the height is made in form of truncated regular pyramid or prism, preferably hexahedral. 22. Fixing-supporting element according to claim 20 or 21, characterized in that the height of cone-shaped part of the end of hollow support is at least equal to the distance between the adjacent turns of outer thread. 23.
