A device for inspectable, demountable and adjustable spring boxes for the low-frequency filtering of floating floors

摘要

Device making it possible to implement floating floors intended to provide active or passive vibrational filtration. The invention relates to pointwise low-frequency elastic supports made up of coil-spring boxes. These spring boxes are installed when the floor is poured (cast), the springs, which are preloaded beforehand, are used for raising the construction by progressive release. The spring boxes can be inspected, dismantled, and adjusted for levelling the floor. IMAGE
