摘要

Device permitting the construction of floating floors (2) intended to provide active or passive filtering of vibrations. The invention relates to low-frequency resilient (elastic) spot-type supports consisting of helical-spring boxes (1). These spring boxes (1) are positioned at the time of casting the floor (2), the springs (5), which are prestressed beforehand, are used for raising the work by means of progressive release. The spring boxes (1) are accessible, demountable and adjustable for levelling the floor (2). <IMAGE>
