    专利说明:

    The invention relates to a baffle element with a base body, which is preferably made of concrete, and which has two end walls and side walls, wherein on the end walls coupling elements are arranged for connection to subsequent baffle elements.
    In particular, the present invention relates to baffle elements, as described in WO 2010/057232 A, WO 2011/088485 A, WO 2012/171048 A and WO 2014/047667 A, which are preferably made of concrete. In such vehicle restraint systems, which serve to safely divert impacting vehicles, depending on the severity of the crash event, parts may be wholly or partially dislodged from the baffle elements. In certain applications (e.g., on bridge structures), such releasing parts may present a danger to other road users or to persons working in the field of vehicle restraint systems.
    The invention is therefore based on the object to improve baffle elements of the type mentioned by the risk of loosening parts is reduced.
    This object is achieved with a guide wall element of the type mentioned at the outset in that a protective layer is arranged on at least one side wall at least in partial areas of the surface.
    Experiments and practical experience in real collision events have shown that certain parts of the baffle elements there is a certain risk of loosening of parts, which is usually the side opposite the impact side and optionally the corner at the transition of the side walls to the end walls. According to the invention, therefore, the protective layer is arranged at least on the subregions of a side wall in which the risk is higher that detach parts of the base body.
    As protective layer all materials or
    Composite materials in question, which have sufficient strength to retain releasing parts of the body, in particular concrete parts of the body. It is preferred if the protective layer has a grid, fabric, knitted fabric, mesh, mesh or knitted fabric or a film or a combination thereof.
    The protective layer can be arranged at least partially on the surface or below it, wherein a combination of these arrangements is possible.
    If the protective layer is arranged at least partially on the surface, it is preferred in the invention if it is connected to the base body at least in the region of its edges, wherein it is further preferred if the protective layer is also connected to the base body in the area between the edges , which is particularly preferred for films or textile-like protective layers, which could be lifted off the surface, for example by wind.
    If the protective layer is arranged under the surface at least in some areas, it is preferred if it is arranged at most 4 cm, preferably at most 2 cm and in particular at most 1 cm below the surface, since in this area usually no reinforcing elements for the main body and in particular parts , which are located between the outermost reinforcing elements and the surface of the body, most likely to dissolve in a collision of the body.
    Further preferred embodiments of the invention are
    Subject of the dependent claims.
    Further features and advantages of the invention will become apparent from the following description of preferred embodiments of the invention with reference to the drawings. It shows:
    Fig.l an arrangement of an inventive
    Baffle element of a vehicle restraint system on an edge element of a bridge structure,
    2 shows a first embodiment of a baffle element according to the invention,
    Fig. 3 shows another embodiment of a baffle element according to the invention and
    Fig. 4 shows a detail of a third embodiment of a baffle element according to the invention.
    In Fig. 1, a baffle element 1 according to the invention is shown, which is located at the edge of an edge element 2 of a bridge structure with a traffic surface 3.-Since with such baffle elements 1, a collision of a vehicle can take place only from one side, the baffle element 1 of this embodiment is asymmetrical executed. The guide wall element 1 of this embodiment has a side wall 4 facing the traffic area 3, which has a so-called New Jersey profile, and a side wall 5 facing away from the traffic area 3, which in this case is a rear wall which is arranged level or vertically is.
    Due to the particular arrangement of the baffle element 1 according to FIG. 1, the risk of parts of the baffle element 1 detaching from the side wall 5 in the event of a collision of a vehicle, which is to be feared in particular if the base body consists of concrete, as this may not absorb the tensile forces occurring in the impact on the outside despite a conventional reinforcement under certain circumstances and therefore can tear.
    In order to prevent any parts that may become detached, there is a risk for in the area next to or below the
    Present vehicle restraint system persons, structures, devices or vehicles, according to the invention a protective layer 6 is provided, which is shown in an embodiment in Fig. 2.
    The baffle element has, apart from the two side walls 4 and 5, still end walls 7, a top 8 and a bottom 9. On the end walls 7, not shown connecting elements are arranged, which can be configured and described, for example, as shown in WO 2010/057232 Al. Since the arrangement and the nature of the connecting elements for the present invention are not essential, they are not described here in detail.
    In Fig. 2, a network is shown as a protective layer 6, which rests loosely on this in the region of the side wall 5 and extends to the top 8 and bottom 9, where it is attached.
    The attachment can be done for example by gluing or embedding, in particular concreting, in the material of the baffle element 1. Alternative attachment methods are, for example, strips with which the protective layer 6 is screwed or clamped in the edge region on the upper side 8 and the lower side 9. Furthermore, it is also possible to attach grooves 10 to the upper side and / or the underside and / or other locations, in which the protective layer 6 is inserted with its edges and cast there or fixed with terminal strips. Corresponding mounting options can also be provided in the region of the side wall 5 at regular intervals to a lifting or fluttering of the protective layer on the
    Side wall 5 to prevent. Of course, it is also possible to attach the protective layer 6 over the entire surface on the Leitwandelement 1, for example, stick.
    An alternative mounting option would be the embedding of the protective layer 1 under the surface 11 of the side wall 5, optionally up to the area of the upper side 8 and the lower side 9, which can be done during the manufacture of the Leitwandelemente 1, especially if they are made of concrete. For example, the protective layer 6 could be placed in a formwork for the baffle element 1, whereby it is then either embedded directly in the surface region of the side wall 5 or, if spacers are used, is arranged at a certain distance from the surface 11 of the side wall 5.
    An example of the latter embodiment is shown in Fig. 4 in detail, wherein in Fig. 4, a reinforcement 12 of the baffle element 1 made of concrete can be seen.
    Of course, if the protective layer 6 is embedded in the material below the surface 11, it is of advantage if the protective layer 6 is well permeable to the material of the guide wall element 1, which is the case for example when using gratings or nets. Protective layers of a non-permeable or poorly permeable material are preferably arranged on or on the surface 11.
    In Fig. 3, another embodiment of a baffle element according to the invention is shown, which in turn has a New Jersey profile in the illustrated embodiment, and for example in vehicle restraint systems between lanes use. In this embodiment, the protective layer on both side walls 4, 4 'arranged.
    At the baffle element 1, two different embodiments of the invention are shown as the protective layer 6 can be arranged on the baffle element 1, these embodiments can of course be combined with each other and with other mounting options.
    On the left side wall 4 of the profile shown in Fig. 3, the protective layer 6 extends between an upper edge 13 and a central edge 14 at a distance from the side wall 4, then lies from the central edge 14 to a lower edge 15 and on the bottom 9 on the Surface on and is glued or mechanically attached in the overlapping area, for example. The latter also applies to an attachment of the protective layer 6 on the upper side 8.
    On the right side wall 4 'of the profile shown in Fig. 3, the protective layer 6 is on the side wall 4' over the entire area closely and is there also by gluing or mechanical fastening means attached. In the case of a mechanical fastening is preferred if at least in the region of the bend 16 strips or punctiform fastening means are provided.
    A not shown in the drawings possibility of the arrangement of a protective layer 6 on a Leitwandelement 1 is a tubular casing which is drawn in the longitudinal direction over the Leitwandelement 1, and which is fixed by placing the Leitewandelementes 1 on the ground in their position, but of course In addition, with the mentioned attachment methods on the main body of the baffle element 1 can be attached.
    Furthermore, the protective layer can be used in any embodiment. extend beyond the edges to the end walls 7, as shown and described at the top 8 and bottom 9. It is also possible to use the main body of the
    Leitwandelementes 1 completely enveloped with a protective layer 6 or a protective layer 6 on all sides än / or embed below the surface 11.
    As a material for the protective layer 6, all materials and possibly also composite materials can be used which have sufficient strength to peeling parts of the main body to hold back. In an arrangement of the protective layer on the surface of the body, the materials must of course also have sufficient weather resistance.
    In one embodiment of the invention, the protective layer 6, if it is visible from the outside, also be designed in multiple colors and act as an information carrier. Possible application examples would be, for example, warnings, such as arrows that indicate a sharp curve, or advertising or tourist information. The multicolored design of the protective layer 6 can be done, for example, by printing or multicolor weaving, if the protective layer is a fabric.
