A barrier system includes first and second barrier segments connected to one another. The connection between the segments includes a pair of wedge-shaped connectors disposed between angled faces formed at the opposing ends of the segments. Elastic pads are sandwiched between the respective segment faces and connectors.

Barrier system

A structural assembly may include a first prefabricated structural element having a first angled face at an end of the first prefabricated structural element; a second prefabricated structural element having a second angled face at an end of the second prefabricated structural element, the end of the second precast barrier segment connected to the end of the first prefabricated structural element; and a coupling assembly connecting the first angled face of the first prefabricated structural element to the second angled face of the second prefabricated structural element. The coupling assembly provides shear and moment continuity across the first and second prefabricated structural elements. This allows for a variable gap due to manufacturing tolerances, construction tolerances, and/or expansion or contraction.

System including adjustable continuity joints and/or rotation mitigation sliding posts for rail elements

A high-impact, energy-absorbing vehicle barrier system generally includes a substantially rigid outer containment wall coupled via strap assemblies with an energy-absorbing inner impact wall, and energy-absorbing cartridges strategically positioned between the impact wall and containment wall. The impact wall is constructed of a number of tubes coupled with one another to present a substantially smooth, uniform surface to passing vehicles. The energy-absorbing cartridges generally consist of a foam member or a number of foam sheets which compress and crush between the containment wall and impact wall to absorb energy from an errant vehicle striking the face of the impact wall, while the deflection and deformation of the impact wall tubes dissipates additional energy to reduce peak decelerations and mitigate the severity of high-energy vehicular impacts. Internal splice units and the strap assemblies provide for relatively easy and quick replacement of damaged impact wall sections and energy-absorbing cartridges.

High-impact, energy-absorbing vehicle barrier system

A high-impact, energy-absorbing vehicle barrier system generally includes a substantially rigid outer containment wall coupled via cable restraint assemblies with an energy-absorbing inner impact wall, and energy-absorbing cartridges strategically positioned between the impact wall and containment wall. The impact wall is constructed of a number of rectangular tubes coupled with one another to presents a substantially smooth, uniform surface to passing vehicles. The energy-absorbing cartridges generally consist of a number of foam sheets which compress and crush between the containment wall and impact wall to absorb energy from an errant vehicle striking the face of the impact wall, while the deflection and deformation of the impact wall tubes dissipates additional energy to reduce peak decelerations and mitigate the severity of high-energy vehicular impacts. The splice units and quick-disconnect cable restraint system provide for relatively easy and quick replacement of damaged impact wall sections and energy-absorbing cartridges.
