  • Spherical bearing

    Spherical bearing

    Request for Price

    mageba RESTON-SPHERICAL bearings ensure the controlled transfer of forces between a structure’s superstructure and its substructure. They also facilitate rotations about every axis and movements in every direction. A convex curved element, sliding on a matching concave surface, transfers vertical forces while allowing the required rotations.

  • Single gap joints

    Single gap joints

    Request for Price

    mageba TENSA-GRIP expansion joints are single gap joints for movements of up to 80 mm in the case of type RS, or 100 mm in the case of Type RS-LS. Type RS-LS joints feature so-called “sinus plates” on their surface, which make this increased movement possible and also reduce noise from over-passing traffic by up to 80%. The joints consist of robust steel edge profiles and replaceable elastomeric sealing profiles, which ensure long-lasting watertightness. The drainage of the joints is via the drainage system of the bridge deck.

    Single gap joints

    Request for Price

    mageba TENSA-CRETE expansion joints are single gap joints for movements of up to 80 mm in the case of type RE, or 100 mm in the case of Type RE-LS. Type RE-LS joints feature so-called “sinus plates” on their surface, which make this increased movement possible and also reduce noise from over-passing traffic by up to 80%. The steel edge profiles of the TENSA-CRETE joint are anchored in ROBO-FLEX, mageba’s quick-hardening and watertight polymer concrete. A key advantage is the quick and cost-effective installation of the system, which results from the joint’s being fully anchored within the depth of the road surfacing and thus requiring no breaking out of the structure beneath. Thanks to the very short curing time of the polymer concrete, traffic can already be allowed to cross the joint within a few hours of placing. The drainage of the joint is via the drainage system of the bridge deck.

  • Shock Transmission Units

    Shock Transmission Units

    Request for Price

    mageba RESTON-STU Shock Transmission Units are used to rigidly connect parts of a structure together under the action of sudden high dynamic loading (e.g. from an earthquake or from the braking of a train or a heavy road vehicle). However, they permit free movement due to slow-acting influences such as temperature changes or shrinkage and creep.

    PENDULUM-sliding-isolation-bearing

    Request for Price

    mageba seismic isolator RESTON-PENDULUM bearings are based on the functional principle of a pendulum. They allow a structure to become horizontally displaced during an earthquake, with seismic energy being dissipated by the friction between various moving components. After the earthquake, the curvature of the sliding surface of the base causes the supported structure to return by gravity to its original position.

    Remote Monitoring System

    Request for Price

    mageba ROBO-CONTROL Permanent is a fully automated remote monitoring system for structures. It uses sensibly located sensors to measure variables (such as loading, deformations and vibrations) that affect a structure’s condition and performance, and can also be used to determine characteristic parameters such as natural frequency. The generated data, measured at predefined intervals, is transmitted to a central computer server, where it is processed and made available to authorised users via a secure website or a network.

    Preloaded Spring Dampers RESTON-PSD

    Request for Price

    mageba RESTON-PSD Preloaded Spring Dampers are designed to dissipate seismic energy in structures, limiting and damping the movements that arise between parts of a structure during an earthquake. Under normal circumstances they act as a fixed connection, preventing movements until a defined preload has been exceeded.

  • modular expansion joints

    modular expansion joints

    Request for Price

    mageba TENSA-MODULAR multiple-gap expansion joints can accommodate movements in every direction and rotations about every axis. They can be used for longitudinal movements of as little as 160 mm, or for very large movements of well over 2,000 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. Type LR-LS joints feature so-called “sinus plates” on their surface, which reduce noise from over-passing traffic by up to 80%.

    mageba ROBO-CONTROL Portable is a mobile, easily deployable structural analysis tool. It uses selected sensors to measure the variables that affect a structure’s condition and performance, such as loading, deformations and vibrations. The high frequency of the measurements enables a large volume of data to be generated in a short time. The on-site measurement and storage of data makes data transmission to a remote server unnecessary.
