Definitions

  • the invention relates to a separating element for traffic surfaces that is made preferably of concrete and that on opposite end faces has at least one connecting element at a time with which it can be connected to a subsequent separating element (AT 405 851 B and EP 1124014 A).
  • separating elements are conventionally coupled to one another by suitable connecting elements in order to form a continuously closed guide wall.
  • These elements that are connected to one another in the end region or on the end faces are generally mounted freely on the foundation.
  • the so-called retaining system acquires its serviceability by the resulting tension member action of this chain that is formed from the separating elements and is able to repel colliding vehicles.
  • the object of the invention is to devise a separating element of the initially named type that improves the transmission of the transverse forces from one separating element to a bordering separating element.
  • a separating element of the initially-named type in that on one end face, there is at least one projection, and on the other end face, there is at least one depression, a projection engaging a depression of a subsequent separating element in order to transfer the forces acting in the plane of the end face from one separating element to a subsequent separating element.
  • the at least one projection that engages one depression of a subsequent separating element makes it possible to better control the force acting on the connecting apparatus and the transfer of the transverse forces that occur between the elements and to route the transverse forces out of the generally more sensitive connecting apparatus to other sites in the end face, for example into the base region of the separating elements, where the elements are generally made more solid.
  • Another advantage of the at least one projection that engages one depression of a subsequent separating element is the effect that the separating elements in the case of collision in the junction region cannot be displaced relative to one another.
  • an offset often occurs between the separating elements since the forces of friction on the mounting surfaces act against the transverse force. This offset or this twisting in the junction region can lead to the corners of the separating elements in the junction region no longer pressing against one another during the buckling that is caused by the impact and thus no longer stiffening the system.
  • the positive connection of the separating elements according to the invention keeps the end faces in their position to one another so that during buckling/displacement of the chain and of the individual elements, the corners continue to strike/press against one another and thus stiffen the system. In this way, the displacement in a case of impact is reduced.
  • the projection and the depression preferably consist of metal, preferably of steel, and are located on a rigid compression plate on the end faces of the separating element and are attached there.
  • the compression plate is connected to the concrete element such that the transverse and compressive forces that occur can be transmitted between the elements and can be routed into the bordering element.
  • a symmetrical version makes it possible for the individual elements to be removed from the closed chain and re-inserted anywhere. This version also allows the elements to be able to be mounted from any side.
  • compression plates are attached in the region of lateral outer edges of the end faces. These can be the compression plates on which the projection and/or the depression are located, but also compression plates independent thereof.
  • Separating elements of guide walls are somewhat displaced first of all in a collision, as a result of which energy from a collision of a motor vehicle is reduced. If the collision is so strong that this small displacement of the separating elements is not sufficient to reduce the energy of the impact, the separating elements that are held together in their middle region by the connecting elements strike one another in the region of their lateral outer edges, as a result of which the originally articulated connection between two separating elements becomes a largely rigid connection.
  • separating elements for traffic surfaces are generally made of concrete and the latter breaks relatively easily especially in the edge region
  • the compressive force between two separating elements is distributed by the rigid compression plates onto a relatively large surface region that can be chosen by the size of the compression plates especially toward the interior of the separating elements, as a result of which the concrete, among others, due to the reinforcement that is present if necessary, is able to absorb much higher compressive forces without breaking
  • the separating elements especially in a collision of heavy vehicles or of vehicles with high speed, are able to absorb these forces in the region of the outer edges or corners without their being destroyed to such an extent that they can no longer accommodate loads that occur.
  • the invention can also be provided that there is a compression plate that passes from one lateral outer edge to the other lateral outer edge.
  • the advantage of this embodiment lies not only in that a very large surface on which the forces are distributed is created by the compression plate that passes from one edge to the other, but also in that the compression plate acts as a type of tension/compression member that extends from one edge to another.
  • the compression plate(s) Even if it were possible for the compression plate(s) to extend over a large part of the height of the end faces or over the entire end face, it is generally preferred if the compression plate(s) is/are located on one lower edge of the end faces since in this region, the outer edges generally lie farthest apart or break most easily.
  • a still more stable embodiment of the invention arises by the compression plate(s) with clips and/or plates extending around the lateral outer edges except for the longitudinal sides of the separating element.
  • the compression plate(s) extend(s) around one lower edge of the end face except for a bottom surface.
  • the separating elements according to the invention can be made such that one connecting element of one separating element with one connecting element of a subsequent separating element defines a pivot and that the pivot is located in one plane of the compression surfaces of the compression elements.
  • a separating element according to the invention can also be characterized in that one connecting element of one separating element with one connecting element of a subsequent separating element defines a pivot and that one plane of the compression surface of the compression element lies on the side of the pivot facing away from the respective separating element.
  • the compression surfaces of adjacent separating elements during a displacement do not immediately strike one another flat on the side regions, but first in a transition region that lies further to the inside between the middle region and the side region.
  • This function can also be achieved or reinforced in that on the side of a compression plate that is located on one side region, which side is adjacent to the middle region, there is a compression element that projects above the surface of the compression plate.
  • an optionally wedge-shaped spacer element can be attached to at least one compression plate.
  • the separating element according to the invention can be characterized in that the compression plate(s) on the side that points toward the interior of the separating element has/have connecting elements.
  • These connecting elements for example setbolts, clamps or the like, can be concreted into a separating element that conventionally consists of concrete and in this way can ensure a very strong connection between compression plate(s) and concrete bodies of the separating element and very good delivery of forces into it.

  • FIG. 13 shows a ninth embodiment of a separating element according to the invention with a seventh embodiment of compression plates.
  • the separating element 1 has two opposite end faces 4 to which connecting elements 5 , 6 are attached preferably in the region of the upper part 2 , and with which one separating element 1 can be connected to further separating elements 1 to form separating walls, guide walls or other retaining systems on roads or other locations, as is shown in, for example, FIGS. 2 and 3 .
  • the separating element 1 is made as inherently known from the prior art and can also be made like the known separating elements largely without limitations.
  • the end face 4 of the separating element 1 has an upper section 4 a, a lower section 4 b, and a middle section 4 c, the middle section 4 c being tilted obliquely from the upper section 4 a down and to the outside.
  • the upper section 4 a lies in one plane behind the lower section 4 b, as a result of which the upper sections 4 a of adjoining separating elements are always spaced apart from one another even if the lower sections 4 b lie against one another.
  • a compression plate 40 made of steel with a projection 41 that is wedge-shaped in this embodiment and a wedge-shaped depression 42 , which each can engage as is shown in FIGS. 2 and 3 on one depression 42 and one projection respectively of an opposite compression plate 40 of a subsequent separating element when they are connected to one another using the connecting elements 5 , 6 .
  • This yields a positive connection between the compression plates 40 which prevents transverse displacement of the separating elements 1 on the compression plates 40 , as a result of which transverse forces can be better transferred from one separating element 1 to a subsequent separating element 1 and the loading of the connecting elements 5 , 6 by transverse forces is reduced.
  • separating elements 1 can be easily connected to one another or separated from one another by one separating element 1 or the other being raised or lowered, and at the same time the connecting elements 5 , 6 can be joined to one another/separated from one another, and one projection 41 on one separating element 1 can be inserted into/withdrawn from one depression 42 on the subsequent separating element 1 .
  • connecting elements 12 are attached that in this embodiment are made as setbolts that with their end opposite the head are welded to the compression plates 40 .
  • the setbolts 12 are cast into the body of the separating element in the production of the separating element 1 and thus constitute a strong connection between the compression plates 40 and the body, generally the concrete body, of the separating element 1 .
  • the compression plate 40 extends in the form of clips 14 around edges 9 to over the side surfaces 15 that adjoin the edges 9 .
  • the setbolts 12 are also located on the clips 14 in order to create a strong connection of the clips 14 to the concrete body.
  • the separating element 1 as shown in FIG. 3 can twist around the connecting region of the connecting elements 5 , 6 , as a result of which a projection 41 more deeply engages the assigned or opposite depression 42 .
  • a stable positive connection is created between the bordering separating elements 1 that is able to accommodate transverse forces that are acting at a right angle to the longitudinal extension of the separating elements 1 or in the plane of the end faces 4 so that the connecting elements 5 , 6 that would otherwise have to accommodate these transverse forces are relieved of these transverse forces.
  • the connecting elements 5 , 6 can be optimized to the tensile forces that are acting in the longitudinal direction of the separating elements.
  • FIG. 4 shows one embodiment of a separating element 1 that consists, as is inherently known, of an essentially trapezoidal upper part 2 and a wider, likewise essentially trapezoidal lower part 3 .
  • the projections 43 and depressions 44 are made semicircular. It goes without saying that also other shapes of projections and depressions can be used, such as roughly trapezoidal geometries, it also being possible for the projections and depressions to combine different shapes or geometries or proportions.
  • the projections and depressions in all described embodiments can be provided only on the compression plates; the compression plates can therefore rest largely flat on the underlying concrete.
  • the projections or depressions can also, however, as well as shown in the drawings, be present on the concrete body and can be covered and protected by the compression plates.
  • the end face 4 of the separating element 1 of FIG. 5 has a middle region 7 and two side regions 8 .
  • the middle region 7 and the two side regions 8 in this illustrated embodiment lie in one plane, the middle region having roughly the width of the upper part 2 and the side regions 8 occupying the area by which the lower part 3 projects laterally over the upper part 2 .
  • compression plates 11 made of metal, preferably stainless steel, are attached and in the illustrated embodiment extend from the middle region 7 to lateral outer edges 9 of the end face 4 .
  • the compression plates 11 can be seated either on side regions that are flush with the middle region 7 and consequently project with the plate thickness over the middle region 7 or can be inserted into depressions whose depth corresponds roughly to the plate thickness so that the free compression surface 10 of the compression plates 11 is flush with the surface of the middle region 7 .
  • One projection 41 is attached to one compression plate 11
  • one depression 42 is made on the other compression plate 11 .
  • corresponding compression plates 11 that are likewise not shown with one projection 41 and one depression 42 each are attached so that adjoining separating elements 1 can be connected to one another analogously to the manner as shown in FIGS. 2 and 3 .
  • connection between two separating elements 1 is shown once in the stretched state ( FIG. 6 ) and once in the buckled state ( FIG. 7 ) in FIGS. 6 and 7 , similarly to as shown in FIGS. 2 and 3 .
  • the middle region 7 is aligned at a right angle to a vertical longitudinal middle plane; conversely, the side regions 8 are located at an angle ⁇ of less than 90° to the vertical longitudinal middle plane.
  • the compression surfaces 10 of the compression plates 11 are located on the side regions 8 at an angle ⁇ of less than 90° to the longitudinal axis of the separating element 1 , the planes of the compression surfaces 10 passing roughly through the pivot between the connecting elements 5 , 6 .
  • the compression elements 11 with their projections 41 and depressions 42 adjoin one another flatly when the separating elements 1 are twisted against one another to the degree as shown in FIG. 7 .
  • the compression plates 11 with their compression surfaces 10 adjoin one another flatly so that for a continuously acting force F, for example in the direction shown in FIG. 3 or 7 , the compressive forces acting between the two separating elements 1 in the region of the compression plates 11 are delivered over a large area into the concrete body of the separating elements 1 so that premature breaking-off of an affected corner region of the separating elements 1 can be prevented.
  • the basic shape corresponds to that of FIG. 5 .
  • the compression plate 13 consists preferably of a one-piece steel plate that is again connected on the side regions 8 via setbolts 12 to the concrete body.
  • FIG. 9 is very similar to the embodiment of FIG. 8 , the compression plate 13 extending in the form of clips 14 around the edges 9 to over the side surfaces 15 that adjoin the edges 9 . There are also setbolts 12 on the clips 14 in order to create a strong connection of the clips 14 to the concrete body.
  • FIG. 10 represents a further development of the embodiment of FIG. 3 in which the compression plate 13 in the form of plates 17 extends in addition around extensions 9 ′ of the outer edges 9 in the region of side oblique surfaces 16 of the lower part 3 .
  • the oblique surfaces 16 are as is known tilted at an angle of less than 90°, preferably at an angle of between 45° and 75°, to the bottom surface of the separating element 1 .
  • the above-described setbolts 12 are also attached to the plates 17 .
  • a bottom plate 18 which also like the one already described is connected securely with setbolts 12 to the concrete body of the separating element 1 , is attached to the compression plate 13 in addition to the clips 14 and the plates 17 on the bottom surface of the separating element 1 .
  • FIG. 12 shows one embodiment of the invention that is not dissimilar to the one of FIG. 11 , but with the difference that similarly to the embodiment according to FIG. 5 , it has separate compression plates 11 that like the embodiment according to FIG. 5 have a projection 41 and a depression 42 , side clips 14 , side plates 17 and bottom plates 18 that are each securely connected by setbolts 12 to the concrete body.
  • separating elements 1 on two opposite end faces 4 there can be the same or similar compression plates 11 , 13 even if this was not described in detail above.
  • the separating elements 1 need not have a symmetrical cross-section, but can also be asymmetrical.
  • FIG. 13 shows one embodiment of a separating element 20 according to the invention that has a simple trapezoidal shape as a cross-sectional shape.
  • the separating element 20 like the separating element 1 on two opposite end faces 4 in the lower third has a trapezoidal compression plate 21 on which a projection 41 and a depression 42 are located and that extends over the entire width of the end face 4 from one outer edge 9 to the other edge 9 .
  • the two compression plates 21 are connected to one another via side plates 23 . Both the compression plates 21 and also the side plates 23 have connecting elements in the form of setbolts 12 , with which they are securely connected to the concrete body.
  • the compression plates to the extent that they are located on the end faces 4 , and also the sections that are angled to the side surfaces and to the bottom surface are bent either from one-piece plates that are welded to one another if necessary on the borders or edges, or they consist of individual plates that are welded to one another.
  • the basic shapes of the separating elements 1 , 20 of the individual illustrated and described embodiments as well as the shapes and the manner of attachment of the compression plates 11 , 13 , 21 of the individual illustrated and described embodiments can be interchanged among one another as desired.
  • the previously illustrated and described embodiments of the separating elements 1 allow a limited pivoting capacity of the separating elements to one another, among others to be able to form curve radii.
  • a spacer element 34 can be attached that fills the resulting gap in order to again enable immediate transfer of compressive forces.
  • the overall system that consists of a series of separating elements 1 , 20 becomes stiffer and opposes displacement in the case of a vehicle impact.
  • one projection 41 and one depression 42 each are attached to each end face 4 . It goes without saying that only one projection 41 or one depression 42 or more than one projection 41 or more than one depression 42 can be located on each end face 4 . Moreover, the projections 41 and depressions 42 need not be attached to compression plates 11 , 13 , 21 , 40 , but can also be attached without compression plates 11 , 13 , 21 , 40 or next to compression plates 11 , 13 , 21 , 40 .
