Abstract
A wall exposed to wear is made up of wear-resisting, impact-absorbing elements (11) and a structure (10, 12, 13) supporting these elements. The elements (11) are elongate and have base portions (15) to permit mounting the elements on the supporting structure, and arch portions (19) of elastomer or plastic material which extend freely between the base portions and directly pass into a protective layer over the base portions. The thickness of the arch portions amounts to 50% at most, preferably about 30-50% of the total thickness of the element, which preferably is at least about 10 cm.
Claims19
A wall which is made up of ear resisting, impact-absorbing elements and a structure supporting said elements which form a wear-resisting, impact-absorbing layer of an elastomer or plastic material, wherein said elements are elongate in a longitudinal direction and comprise
- spaced-apart base portions to permit mounting said elements on said structure, said base portions being spaced-apart in a transverse direction and having a length extending in a longitudinal direction, and
- arch portions formed of said wear-resistant elastomer or plastic material and extending freely between said base portions, said arch portions also longitudinally extending for the longitudinal length of said base portions, and
- each element having at least two base portions and one arch portion between each pair of adjacent base portions.
A wall which is made up of wear resisting, impact-absorbing elements and a structure supporting said elements which form a wear-resisting, impact-absorbing layer of an elastomer or plastic material, wherein said elements are elongate in a longitudinal direction and comprise
- spaced-apart base portions to permit mounting said elements on said structure, said base portions being spaced-apart in a transverse direction and having a length extending between a first and a second end, and
- arch portions formed of said wear-resistant elastomer or plastic material and extending transversely between said base portions, said arch portions also longitudinally extending for the longitudinal length of said base portions, and said arch portions having a first end essentially coplanar with the first end of said base portions and a second end essentially coplanar with the second end of said base portions, and
- each element having at least two base portions and one arch portion between each pair of adjacent base portions, and
- stiffening ribs which are formed along a lower surface of said arch portion and which extend transversely between said spaced-apart base portions and which are serially spaced along the longitudinal length of said arch portion.
A wall as claimed in 13 wherein each base portion has a stiffening or reinforcing metal member embedded in or vulcanized to the elastomer or plastic material.
A wear-resisting, impact-absorbing wall element which includes a wear-resisting, impact-absorbing layer of an elastomer or plastic material, wherein the element is elongate in a longitudinal direction and comprises:
- spaced-apart base portions to permit mounting said element, said base portions being spaced-apart in a transverse direction and having a length extending in a longitudinal direction, and
- an arch portion formed of said wear-resistant elastomer or plastic material and extending freely between said base portions, said arch portion also extending for the length of said base portions,
- said element having at least two base portions and one arch portion between each pair of adjacent base portions, and said element having one or more transverse stiffening ribs which are integrally formed with said arch portion and have a free edge which is located within the arch portion at a distance from a plane defined by said two base portions.
