<p>The elastic floor (1) has transverse undulations (5) enabling the floor to follow the relative displacements of the carriages on curves. It comprises an elastic material mat (2) the lower face of which is placed on the upper face of the floor. The mat covers a part of the zone having an undulated surface. The mat includes in its lower face ribs (25) which penetrate into hollow regions. Certain ribs have a complementary section to the hollow regions (19) of the undulations. Certain ribs have a region edging the lower face of the mat which have a play with the hollow regions of the corresponding undulations when the mat is placed on the floor.</p> |
