Definitions

  • the invention relates to a coupling element configured to form part of a first barrier element and to form part of a connection between the first barrier element and a second barrier element.
  • the invention also relates to a barrier element comprising a first and a second coupling element being arranged at a respective end of the barrier element.
  • the invention also relates to a barrier comprising a plurality of barrier elements.
  • barrier In order to improve road safety, it is common practice to separate different traffic areas from each other by some kind of barrier or separator. Different traffic areas may e.g., be on one side one more lanes of traffic travelling in a first direction and on the other side one or more lanes of traffic travelling in a second, opposite, direction. Barriers may of course be used for various other reasons, such as protecting road vehicles from hazards just outside the road, protecting surrounding environment from the hazard of vehicles leaving the intended lane, providing a safety separation between neighboring lanes, etc.
  • the barrier may be in the form of metal rails, wire rails, or concrete barriers. Concrete barriers are typically formed of elongated barrier elements which are positioned one after the other. The barrier elements of concrete are heavy, and they are typically also interconnected to each other, whereby they form a strong barrier capable of sustaining heavy impacts from vehicles being heavy and/or traveling at high speed.
  • Each barrier element is provided with a respective connecting element at each end face of the barrier element.
  • Each connecting element comprises one leg having hook portions on both transverse sides thereof and one leg having an inwardly facing hook portion. The leg having two hook portions will interact with one hook with a corresponding leg of another connecting element and one hook with the single hook leg of the other connecting element.
  • the designer should preferably take into account several design criteria, such as that the connecting element should be strong, it should be easy to produce, it should be easy to interconnect with similar connecting elements of neighboring barrier elements, and that there should be provided a strong connection between the connecting elements at the opposing ends of the respective barrier element.
  • a coupling element configured to form part of a first barrier element and to form part of a connection between the first barrier element and a second barrier element, the coupling element being configured to extend along a longitudinal direction from the first barrier element to a free end of the coupling element, the coupling element comprising as seen along the longitudinal direction :
  • the two inclined abutment surfaces are capable of transferring high loads between interconnected coupling elements. Moreover, the two inclined abutment surfaces will transfer load both by the inclined surfaces of the respective coupling element blocking each other's paths and by frictionally engaging each other whereby there will be a smooth load build-up. Moreover, the concept of having inclined abutment surfaces also makes the design comparably insensitive to deviations in shape. This makes it possible to have comparably wide tolerances, which in turn facilitates and reduces costs associated with manufacture.
  • the comparable insensitivity to deviations also makes the system robust in the sense that it is capable of providing the intended function although the barriers are misaligned due to misplacement and/or due to the fact that they accommodate a curve or the like in the road where they are positioned.
  • the comparably insensitivity also makes the system robust in the sense that it is capable of withstanding high loads also when being deformed by e.g., a vehicle having crashed into the barriers.
  • the coupling element should be able to withstand transversely directed forces but that typically the dimensioning force will be a longitudinally acting force since any impact onto the barrier will tend to lead to a slightly transversal displacement of the barrier which in turn will basically be transformed into a tendency of a longitudinal separation of neighboring barrier elements.
  • longitudinal refers to the direction along which the barrier element extends between the coupling elements at each end of the barrier element.
  • the longitudinal direction typically extends along the ground.
  • the transversal direction is transverse to the longitudinal direction and typically extends along the ground. From above refers to a direction directed downwardly along the normal to the ground. If the barrier element is positioned on a flat horizontal surface, the longitudinal and the transverse directions will typically be horizontal and the direction from above will typically be downwardly along vertical. In the description below, reference to directions will for clarity reason typically be referred to as if the barrier element is positioned on a flat horizontal surface.
  • the inner side of the first protrusion refers in this context to the side facing the recess of said coupling element.
  • the inner side of the first protrusion of a first coupling element will in installed state face an inner side of a first protrusion of a coupling element of another barrier element.
  • Outer side is the other side of the first protrusion compared to the inner side.
  • the outer side of the second portion of the first protrusion of a first coupling element will in installed state face a second protrusion of a coupling element of another barrier element.
  • the coupling elements of the two neighboring barrier elements are configured to be coupled together by one of the barrier elements, such as the second barrier element, being moved vertically relative to the other barrier element.
  • the barrier elements are moved into the intended position one after the other by a crane or the like.
  • the barrier elements are lifted up from a trailer or the like and are lowered into position such that the coupling element of the second barrier element becomes coupled with the coupling element of the first barrier element.
  • the cross-section disclosed is as seen from above, i.e., typically downwardly along vertical.
  • the coupling elements have essentially uniform cross-section along vertical. In the preferred embodiment, they have uniform cross-section along vertical.
  • the first barrier may have a coupling element being provided with a bottom portion forming a floor or the like below the portion interacting with the coupling element of the second barrier.
  • the second barrier element may have a coupling element being provided with a top portion forming a lid or the like above the portion interacting with the coupling element of the first barrier.
  • any such additional parts or portions will typically make the barrier elements asymmetric such that they have one coupling element of each kind in respective end which makes it necessary to always interconnect this specific combination of coupling elements with each other, which in turn means that every barrier element can only be oriented in one correct direction.
  • the coupling elements and respective barrier element are symmetrical and preferably also identical in the sense that a second barrier element can be coupled to a first barrier element irrespective of which ends of the first barrier element and second barrier element are combined with each other. It may in this context be noted that the different features, portions, parts, details, etc. of the coupling element disclosed above and, in the following, typically refers to the design of the cross-section as seen from above.
  • first and second inclined abutment surfaces are as seen in the cross-sectional view formed of a straight line.
  • the first and second inclined abutment surfaces will form planar surfaces.
  • the planar surfaces extends along vertical.
  • the second protrusion may have on a side forming part of the recess a hook portion with an abutment surface which faces in a direction which has a component along the transverse direction being directed away from the first protrusion and a component along the longitudinal direction being directed towards the attachment portion.
  • the first protrusion has on an outer side of the second portion a hook portion with an abutment surface which faces in a direction which has a component along the transverse direction being directed towards the second protrusion and a component along the longitudinal direction being directed towards the attachment portion, the hook portion of the second portion being configured to interact with a hook portion of the second protrusion of the coupling element of the second barrier element.
  • the first protrusion has a corresponding hook functionality. Thereby, the advantage provided by the hook functionality of the second protrusion is even more pronounced.
  • a hook portion of any of the first and second portion may alternatively interact with a transversally extending abutment surface of the other member. It may in this context also be noted that the hook portions may altogether be replaced with transversally extending abutment surfaces on both the first and second protrusion. However, it is preferred that at least one of the first and/or second protrusion is provided with a hook portion interacting with a transversally extending surface and it is most preferred that both the first and second protrusion are provided with a respective hook portion.
  • the transversely narrow root portion of the second portion is formed by the second portion being provided with a recess on an outer side of the second portion and by the second inclined abutment surface on an inner side of the second portion.
  • the recess allows a portion of the second protrusion of the other coupling element to extend around the transversely wide end portion of the first protrusion.
  • the transversely wide end portion of the second portion is formed by a transversely extending protrusion on an outer side of the second portion and by the second inclined abutment surface on an inner side of the second portion.
  • the protrusion may also be said to form the basis of the hook portion or that the hook portion forms part of the protrusion.
  • the abutment surface of the hook portion forms part of the recess.
  • the first and second inclined abutment surfaces may each form an angle ⁇ relative to the transversal direction, the angle ⁇ being between 40-65°, preferably between 45-60°. It may be noted that the angle ⁇ of the first inclined abutment surface may be the same or may be different from the angle ⁇ of the second inclined abutment surface. It is preferred that if the inclined abutment surfaces have different angles ⁇ the difference between them is less than 5°. As indicated, it is preferred that the inclined surfaces are inclined such that their respective angle is about 45°; slightly below or a bit larger than 45°, preferably between 40-65°. It is more preferred that the angle ⁇ is between 45-60°. It may in this context be noted that it is more preferred that the angle ⁇ is greater than 45° but not too large, i.e., greater than 45° but only up to 65°, preferably only up to 60°.
  • the first inclined abutment surface is angled an angle ⁇ between 50-55° and the second inclined abutment surface is angled an angle ⁇ between 51-56°, preferably with the second inclined abutment surface being angled about 0-2° more than the first inclined abutment surface.
  • the reason for the angles preferably being slightly different is that when a vehicle hits the side of the barrier, the barrier elements and thereby the two coupling elements are typically slightly pivoted relative to each other and the preferred slight difference in angles allows the inclined surfaces to be oriented close to parallel also in such a scenario, whereby a strong interconnection will be accomplished independently of the different incident scenarios.
  • the attachment portion may, as seen from above, have a cross-section which comprises a first and a second longitudinally extending leg.
  • the provision of legs provides anchor points by which the coupling element may by secured to the barrier element.
  • the longitudinally extending legs arranged at a mutual transverse distance from each other. Thereby, the capability of taking up a transversely directed force to the coupling element is improved.
  • a barrier element comprising a first coupling element and a second coupling element, each being of a kind disclosed above, wherein the first and second coupling elements are arranged at a respective end of the barrier element.
  • the barrier element is designed such that the first coupling element is positioned and oriented as viewed towards a first end of the barrier equal to a position and orientation of the second coupling element as viewed towards a second end of the barrier such that the barrier element presents a coupling element of the same position and orientation independently of if the first end or the second end is presented to another barrier element.
  • the barrier element may further comprise one or more interconnecting rods extending between and being fixed to the first and second coupling elements. Thereby, a strong connection between the first and second coupling elements may be achieved.
  • said one or more interconnecting rods includes at least two interconnecting rods extending along each other and at a mutual distance from each other along the transverse direction and/or along a height direction.
  • the barrier element comprises four interconnecting rods extending along each other with a first pair of rods extending along each other at a mutual distance from each other along the transverse direction and a second pair of rods extending along each other at a mutual distance from each other along the transverse direction where the first pair of rods extends at a first height and the second pair of rods extends at a second height such that there is along the height direction formed a distance between the rods of the first pair and the rods of the second pair.
  • a strong interconnection between the first and second coupling elements is accomplished both with respect to transversally directed forces and with respect to vertically directed forces.
  • the barrier element further comprises a body of concrete, wherein the first and second coupling elements are preferably interconnected via one or more interconnecting rods extending within said body of concrete.
  • a barrier comprising a plurality of barrier elements of the kind disclosed above, wherein the barrier elements are arranged one after the other along the longitudinal direction and being interconnected with neighboring barrier elements via the respective coupling elements.
  • the invention may also in short be said to relate to a coupling element comprising a coupling portion having a cross-section which comprises a first longitudinal protrusion and a second longitudinal protrusion between them forming an open recess which has a transversely wide bottom portion and a transversely narrow mouth portion and which is configured to receive, by a relative vertical movement between first and second barrier elements, a first protrusion of a corresponding coupling element of the second barrier element, wherein the first protrusion has a first portion and a second portion arranged one after the other along the longitudinal direction, wherein the first portion has on an inner side a first inclined abutment surface and the second portion has on an inner side a second inclined abutment surface.
