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.

A crash barrier system includes upper posts, box beams, upper tube profiles and barrier rails. The box beams are connected to the upper posts on a front side of the crash barrier system. The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.

A crash barrier for road highways is designed to provide a progressively increasing resistance to impact, which is designed with the sturdy fabrication of creosote-treated and HDPE-coated bamboo poles. Which is weatherproof and long-lasting, highly resistive against fungal, borer, termite attacks and working on using flexibility to dissipate the kinetic energy from a collision. In one embodiment a beam (2) comprising a club of three separate poles 2(a), 2(b), 2(c) is mounted on upright posts (1) consisting of three poles 1(a), 1(b), 1(c) placed triangularly at an angle of 60 with each other with connecting elements (3, 4). The rear elements (4) are of bamboo with node and are relatively stiff while the front elements (3) are hollow tubular and therefore more easily deformed. The deformable connections are fabricated with high tension GI wire rope 7, fixed with U clamps 9, and locked with crimping locks 8.

A barrier having first and second spaced posts interconnected by a rail, wherein the rail and posts are not inserted within one another. In the exemplary embodiments, the parts are hollow in at least the region of the intended interconnection. Each post is connected to the rail by a coupling. Each coupling includes a connector that extends inside the hollow region of the post and rail. The post includes an aperture wherein when assembled the connector extends through the aperture. The connecter includes an abutment that abuts an inside of the post to prevent movement of the connector through the aperture. The connector is moveable further into one of the hollow sections of the post or rail to withdraw the connector from the other of the post or rail. This allows the rail to be disconnected from the post without increasing the distance between the two spaced posts.

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.

A crash barrier is provided including: a first outer layer; a second outer layer spaced apart from the first outer layer; and a plurality of spacer blocks which are arranged between the outer layers, the crash barrier being divided along its longitudinal extent into at least two partial sections which are joined by at least one connecting element which has a first longitudinal section, a second longitudinal section and a third longitudinal section, the first and third longitudinal sections being designed to each be connected to a partial section, and the second longitudinal section connecting the first and third longitudinal sections to one another. A method for installing such a crash barrier is also provided.

A vehicle collision impact reduction device for reducing the force of an impact with a vehicle includes a tube defining an interior space that is designed to hold air. The tube has a pair of ends and is elongated between the pair of ends. A mount is coupled to each end of the pair of ends of the tube. The mount is designed to couple the tube to a structure. The tube is designed to absorb force from an impact with the structure. A cover is coupled to the tube. The cover includes a canvas material wherein the cover is designed to inhibit damage to the tube. A fill valve is coupled to the tube. The fill valve is in fluid communication with the interior space wherein the fill valve is designed to facilitate increasing an air pressure within the interior space.
