The best solution to prevent damage to bridges and viaducts

The expansion joint is an elastomeric device that supports the relative movement between two structural elements on a bridge or road. Its main functions are:

  • Allow the free movement of the plates, supporting the transmitted loads.
  • Continue the road, supporting the traffic load
  • To avoid noise, impacts and vibrations.
  • Provide an adequate seal and allow the evacuation of water.

The expansion joints are made by an internal steel structure, designed to prevent deformation of the joint and allow a smooth transition between plates in any expansion conditions, while reducing as much as possible the loads generated in the elastomer and which are transmitted to the board fixing screws.

    SC42-80

    The Herflex system allows the absorption of medium movements due to its elastic element of multidirectional deformation. It supports larger gaps than theoretical ones. Effective sealing, low maintenance and easy replacement are guaranteed. The HERFLEX SC models cover a range of movements ranging from 42mm to 80mm.

    SC100-330

    The Herflex system allows the absorption of large movements due to its elastic element of multidirectional deformation. It supports larger gaps than theoretical ones. Effective sealing, low maintenance and easy replacement are guaranteed. The HERFLEX SC models cover a range of motion ranging from 100mm to 330mm.

    HF210-380

    The Herflex system allows the absorption of medium movements due to its elastic element of multidirectional deformation. It supports larger gaps than theoretical ones. Effective sealing, low maintenance and easy replacement are guaranteed. The HERFLEX HF models cover a range of movement ranging from 210mm to 380mm.

    SCB50-75

    Designed to accommodate movements in structures that do not support heavy and intense traffic, with low load transfer to slabs or slabs. Maximum traffic comfort and durability.
    Both profiles are supplied in lengths of 1.83m, for anchoring them on boards or forged using chemically fixed anchors.
    The movement is absorbed by the deformation of a resistant central membrane. Impact loads are absorbed by the elastomer and are not transmitted directly to the fixing anchors
    The HERFLEX SCB50 and SCB75 models cover a range of movements of 50 mm and 75 mm, respectively.

    SCM

    The Herflex SCM system is designed for large movements. They are formed by a movement module and a bridge module. The movement module is the moving part formed by rubber and steel, adjusting the planned movements. The metallic module (bridge module) is responsible for connecting the structural space. The HERFLEX SCM models cover a wide range of movements ranging from 400mm to 1600mm.
