ABSTRACT:
A sound proofing and vibration dampening connecting element (B) for floating suspension of a floor-deck on a structural, load-bearing carriage floor of railway vehicles for passenger transport features a base section (28) that is U-shaped in cross-section and, projecting partly over this, a deck-supporting section (38) that is U-shaped in cross-section with base strips (30, 40) having flanges (32, 42) projecting perpendicularly from them. Between the pairs of facing flanges (32, 42) and adhesively bonded to them are elastic profiled strips (46) that, along with base strips (30, 40) forming the contact surfaces for the carriage floor (26) and floor-deck (27), delimit a hollow space (47).
