Reinforced elastomeric bearings

The Neoarm series includes structural bearings of reinforced elastomer, consisting of an elastomeric block in which steel laminates hot vulcanized to the rubber are inserted on multiple laminates, with the main purpose of minimizing the swelling and slipping of the rubber under load. Neoarm structural bearings in general are used if the span of the beam does not exceed 20 m, if rotations are not extreme, if displacements are small and horizontal thrusts are limited. Nevertheless, they are sometimes made in large dimensions. By vulcanizing a wedge-shaped steel plate to the upper surface of the rubber, it is possible to install this type of bearing under beams of considerable slope. Notes: Even if elastomeric bearings are designed to consider shear movements, they should not be used to oppose permanent resistance against an external shear force applied on a constant basis. This means, for example, that they should be placed horizontally on the plane even if the deck is sloping. Please
