Steel Laminated Elastomeric Bearings

Elastomeric and steel bearings.

Steel laminated elastomeric bearings. Elastomeric laminated bearings elastomeric laminated bearings elb s are made from high purity elastomers which encapsulate layered internal steel reinforcing plates. High capacity steel plate laminated bearings also known as elastomeric bearings laminated bearings or elastomeric laminated bearings granor has supplied specially designed laminated bearings up to 800 x 800 x 321 mm. Designed for use in bridge and building construction under pre cast concrete beams steel beam supports and other support points. Elastomeric and steel bearings.

Steel laminated elastomeric bearings are preferred due to their versatility and lack of required maintenance. Versiflex elastomeric bearing components laminated design the addition of internal steel plates or laminates increases the vertical load bearing capacity and the amount of horizontal deflection which can be accommodated by the bearing device. Meets the can csa s6 06 standard and ontario opss 1202. Conforms to astm a 1011 grade 36 thickness of at least 3 mm.

Series el bearings are molded bearings made of high quality natural rubber or neoprene with steel plates vulcanized to the elastomer in such a way that no part of the steel is exposed. This bearing is the connection between a structure and its support and should make the following possible through elastic deformation. Standard un reinforced bearing pads and strips. Laminated elastomeric bearing pad one type of reinforced elastomeric bearings is made of multi layer rubber and reinforced with steel plate through sulfuration and adhesion compared with non reinforced elastomeric bearing it has sufficient vertical rigidity which can reliably transfer the concentrated down loads and impact loads of the superstructure to both ends of the pier.

Introduction elastomeric bearings introduced nearly 60 years ago laminated steel elastomer bearing pads are now in service in tens of thousands of bridges and similar structures throughout the world. There is good reason for this. A laminated elastomeric bearing is an elastomeric rubber block reinforced with steel plates vulcanised when built. Laminated elastomeric bearing features reinforced steel plates that are sandwiched between layers of rubber through vulcanization and molding manufacturing process to form a homogeneous unit.

Not only do these embedded steel plates limit excessive expansions but also increase transversal longitudinal and compressive strength as well as rotation capability comparing with plain elastomeric. They support vertical loads with minimal compression allow expansion and contraction of. These pads are manufactured from alternating layers of neoprene or natural rubber and steel sheets and are molded under heat and pressure vulcanization process into one unit.
