Abstract
The resistance of structural elastomer products, such as bearing blocks, to compressive forces is reduced by incorporating therein a plurality of small, separate, reinforcing elements of relatively hard material. Such materials include crushed rock, concrete, glass or certain slags and small metal pieces. The reinforcing elements are congregated in an interior section or core which is covered by a marginal section substantially free from reinforcing elements.
Claims8
In a bridge or the like the combination of a supporting member, a supported member, and an intermediate load-bearing member in contact with both said supporting member and supported member;
- wherein the load-bearing member comprises a body of elastomer having embedded therein a plurality of separate non-lamellar crushed reinforcing elements of relatively hard material, said elements being present in sufficient quantity as to be effective to reduce the deformation of said load-bearing member by compressive forces.
