Improved composite structure for vibration damping, comprising at least two superimposed plates of plastic material.

摘要

P Improved composite structure for damping vibrations comprising at least two superimposed plates of elastic material, respectively a bottom plate intended to come into contact with the ground, and a top plate (B) intended to receive the emitting assembly the vibrations to be damped, these plates being in mutual contact by their opposite faces comprising rectilinear grooves (11, 12) of complementary profile, the projecting parts of one plate being fitted into the corresponding recessed parts of the other plate , is characterized in that the external face (15) of the top plate (B) has a raised border (25) comprising at the level of the upper face (15) a notch (26) arranged in the same plane as this external face (15). /P
