Steel laminates - Import export

These are structural bearings consisting of an elastomeric core in which one or more steel laminates are inserted, hot vulcanized to the rubber. The presence of the laminates determines a vertical (axial) stiffening effect and the simultaneous reduction in the rubber swelling. Curing has two purposes: one is to convey the rubber tangential actions to the laminate and the other is to ensure the protection of steel against corrosion. Reinforced elastomeric bearings Fixed Elastofip (EF) bearings are a cross between the fixed and free sliding type of bearings, as they permit deformations in all planar directions, but at the same time produce elastic reactions proportional to the deformations. Rotations around any one axis are permitted by the rubber deformability. These bearings are divided into two types: WITHOUT MECHANICAL ANCHORS Neoarm 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

The Elastofip series includes reinforced elastomeric structural bearings, equipped on top and bottom with mechanical anchors. These are structural bearings consisting of an elastomeric core in which one or more steel laminates are inserted, hot vulcanized to the rubber.

Curing has two purposes: one is to convey the rubber tangential actions to the laminate and the other is to ensure the protection of steel against corrosion. Fixed Elastofip (EF) bearings are a cross between the fixed and free sliding type of bearings, as they permit deformations in all planar directions, but at the same time produce elastic reactions proportional to the deformations. In Elastofip (EM) free sliding bearing types and Guided sliding Elastofip (EU/EU*) longitudinal/transversal bearings, on the contrary, the mutual sliding of plane surfaces, one of stainless steel and the oth
