  • Typical movements: 120 to 2500 mm

  • Exceptional movement flexibility

  • Modular design, bolted connections for easy maintenance

Principle

mageba TENSA-MODULAR multiple-gap expansion joints can accommodate movements in every direction and rotations about every axis. The expansion joints can be used for longitudinal movements of as little as 120 mm, or for very large movements of well over 2,400 mm. The total movement of the bridge deck is divided among a number of individual gaps which are created by horizontal surface beams. The individual gaps are sealed by watertight elastomeric profiles, and surface beam movements are regulated by an elastic control system. The drainage of the joint is via the drainage system of the bridge deck.

Applications

TENSA-MODULAR expansion joints are used when the movements of a bridge exceed the capacity of a single gap joint or other expansion joint types for small movements. The watertight system, which was invented by mageba several decades ago, is designed on a modular basis and can be tailored to satisfy the specific requirements of almost any structure.
