Definitions

  • the invention relates to a movable barrier element, comprising a beam-shaped body provided on at least one outer end with connecting means, which are adapted to absorb kinetic energy and which comprise at least one deforming member, the stiffness of which is less than that of the beam-shaped body,
  • a barrier element is known from the AT-B-387808 and is used particularly for erecting temporary barriers along roads, for instance at places where work is being carried out on the road.
  • conventional movable barrier elements After being placed in position, conventional movable barrier elements are either fixedly or hinged connected to each other.
  • a barrier is obtained with very great rigidity which thus provides good protection under all conditions for personnel and/or vehicles present behind the barrier, while a hinged connection results in a barrier which can easily be placed in a desired form.
  • the above mentioned prior art document AT-B-387808 therefore discloses a movable barrier made up of concrete segments, each of which is provided in its end faces with a vertically extending C-shaped space.
  • the end faces of each segment are straight and extend prependicularly to the longitudinal axis of the segment.
  • the segments are connected by means of a coupling piece that is provided at its ends with two T-shaped parts which may be slid into the C-shaped spaces.
  • the coupling piece is deformable, so that the segments may also be arranged in a curve and furthermore the coupling piece may easily be removed after a collision.
  • a moveable barrier which has end faces extend perpendicularly to the surface of the road, but are inclined relative to the longitudinal axis of the barrier element, the purpose of this inclination being a reduction of the risk to a colliding vehicle in case two adjacent barrier elements are not perfectly aligned.
  • the barrier element of this prior art document comprises a space at its foot for receiving an armed concrete connecting member having a locally narrowed cross-section which acts as a designated failure area.
  • the end faces of this prior art barrier element are inclined relative to the longuitudinal axis of the element, they are still prependicular to the surface on which the element rests.
  • the invention therefore has for its object to provide an improved movable barrier element of the above described type.
  • Preferred embodiments of the barrier element of the invention form the subject-matter of the dependent claims.
  • the invention also relates to a movable barrier formed by a plurality of mutually connected barrier elements of the above described type.
  • the invention relates to a method for forming a movable barrier by placing a plurality of movable barrier elements one after another in lengthwise direction and mutually joining the elements by means of connecting means placed therebetween.
  • a method is also known from AT-B-387 808.
  • the method of the present invention is distinguished from this prior art method in that each barrier element has an at least partially sloping end face, that during placing each barrier element is placed adjoining the preceding element, the connecting means are subsequently arranged and finally the element is lowered, wherein the element performs a partly horizontal movement as a result of the slope of the end face whereby the connecting means are placed under bias.
  • the effectiveness of the thus formed connection is hereby greatly improved.
  • a barrier 20 which can be used for instance as temporary crash barrier along a road at a location where work is being carried out on the road, is constructed from a plurality of mutually connected, identical movable barrier elements 1 (fig. 1). It is important that the barrier 20 is sufficiently robust to adequately protect the personnel and/or vehicles present behind the barrier 20 in the case of collision) indicated here with arrow A), but is on the other hand sufficiently deformable to limit as far as possible the damage to the colliding vehicle and the occupants thereof. The deformation of barrier 20 is indicated here with dashed lines 1'.
  • Each barrier element 1 is formed by a beam-shaped body having a relatively broad lower part 5 and a relatively narrow upper part 4. A very stable placing of barrier element 1 on a ground 6 is hereby effected. This is important, as a part of the kinetic energy of a vehicle in the case of a collision must be absorbed in the form of frictional energy between the bottom 5 of the element 1 and the ground 6. From structural considerations the barrier element 1 in the shown embodiment is slightly pagoda-shaped and provided in its side surface with two fold lines 11, 12. From considerations of stability the beam-shaped body of barrier element 1 can take a solid form (fig. 3) but may also be hollow in order to make the barrier element 1 easier to transport. After placing of barrier element 1 the hollow internal space 19 can herein be filled with for instance water or sand to increase the stability of the barrier 20.
  • each element 1 is provided on its outer ends with connecting means 13, 16 whereby it is connected with its adjoining elements 1.
  • the connecting means 13, 16 are herein adapted to absorb the greatest possible amount of kinetic energy.
  • the connecting means 13, 16 are formed by coupling means 16 which hold together the elements 1 and thus ensure that the greatest possible number of elements 1 takes part in absorbing the kinetic energy through displacement thereof, and deforming means 13 which absorb the kinetic energy by deforming.
  • the coupling means 16 comprise a hook 17 incorporated in one of the elements 1 which co-acts with an eye 18 incorporated in the other element 1 to form a tension connection, while the deforming means 13 are formed by two deforming members 14, 15 arranged on the end surfaces 2, 3 of elements 1.
  • the deforming members 14, 15 can for instance be manufactured from an elastic material such as rubber, whereby they can take on their original shape again after a collision and are therefore re-usable, but it is also conceivable to make use of plastically deformable members, for instance metal or plastic "crush zones". These will of course have to be replaced after a crash.
  • the end faces 2, 3 of the mutually adjoining elements 1 are each provided with a fold line 7, 8 whereby a sloping part 9 respectively 10 is formed on which the deforming members 14, 15 are arranged.
  • a combined shifting and rotation movement of barrier element 1 hereby results in a comparatively large displacement in the main deforming direction of the deforming members 14, 15. It will otherwise be apparent to the skilled person that differently formed deforming members, or only one deforming member, could also be applied.
  • connection between two mutually adjoining elements 1 is placed under bias, whereby possible clearance between the elements is removed and, in the case of a collision, kinetic energy can thus be passed directly from the one element to the other without there being a spurious movement to span the clearance wherein no energy is absorbed.
  • Biasing of the connecting means is elucidated with reference to fig. 4.
  • the coupling means 16 are formed by a coupling member 21 inserted in recesses 22 of the barrier elements 1.
  • the coupling member 21 therein has a substantially I-shaped section formed by a web 26 and two flanges 27, while both recesses 22 are each practically T-shaped.
  • Recesses 22 are not arranged directly in element 1 though, but form part of a coupling piece 23 which is arranged in a space 24 in element 1 and connected to the reinforcement steel 25 of element 1.
  • a subsequent element 1 is raised in each case, for instance by means of a crane or, in the example shown, a forklift device 29 engaging in drainage recesses 28 of element 1, and placed with its end surface 2 against the end surface 3 of the preceding element 1.
  • the new element 1 for placing is then carried downward so far that the recesses 22 in both elements 1 partly overlap each other, whereafter the coupling member 21 is placed in both recesses 22.
