MODULAR EXPANSION JOINT

Product Description

NEC Modular Expansion Joints consist in the traffic direction of a succession of watertight elements (seal) comprising movement controlled metal beams (centre beams), supported by moveable substructures bridging the structural gap i.e. cross beams, cantilevers or pantographs. The metal beams are flush with the running surface. The assembly of watertight elements, centre beams and substructures is situated between edge beams, rigidly and in a watertight manner connected to the main structure. The top surfaces of the centre beams and edge beams are flush with the running surface. Where seals are flush with the running surface, they are not designed to carry the traffic loads.
