Abstract:
A track bed matting comprising an elastic band-shaped base (1, 1â€²) made of rubber or rubber-like material for insulating and absorbing vibrations and impact sound, wherein the matting is equipped with tubes (2, 3, 6, 7) arranged with spacings between each other and having a substantially semicircular, semi-oval or semi-ellipsoidal cross section, wherebya portion of the tubes (2, 3) comprises a first plane (I) and a second plane (II) arranged with a spacing A relative to each other, forming a continuous intermediate covering (5) extending parallel with the ground side (4) of the matting (1, 1â€²), the tubes (2, 3) of said two planes (I, II) being arranged displaced against one another with a spacing C, forming a substantially symmetric lattice structure, whereby the spacing C of the displacement amounts to about half of the spacing E from the center of one tube to the center of the other tube within one plane (I, II); wherein all flattened sides of the tubes (2, 3) of the first plane (I) and the second plane (II) face the intermediate covering (5); and that another portion of the tubes (6, 7) comprises a third plane (III) arranged in a space Aâ€² from the next-disposed second plane (II), forming a continuous intermediate covering (8), extending parallel with the ground side (4) of the base (1â€²), whereby the tubes (6, 7) of the third plane (III) each are disposed directly above the tubes (3) of the next-disposed second plane (II).
