(54)	A floor structure

(57) A vibration-damped floor structure has a supportive floor part in which a false ceiling is resiliently suspended by virtue of the ceiling joists 5 springing at their suspension points 13. Damping means 15, 17 that have viscous characteristics are coupled between the floor part and the ceiling. The damping means include a butyl rubber mass 17 which, in one example, adheres to a part 15 which is rigid with respect to the floor part, and to a part 5 which is rigid with respect to the ceiling and subjected to shear in response to vibratory movement between said floor part and said ceiling.
