    专利说明:

    The invention relates to a connection of two baffle elements of a Betonleitwand with a stationary, preferably made of cast-in-place, first baffle element having a bottom surface, an end face and side surfaces, and with a preferably longitudinally aligned mobile second baffle element having a bottom surface, an end face , which faces the end face of the first guide wall element, and has side surfaces, wherein the first guide wall element and the second guide wall element are connected to one another at the end faces via a first positive coupling.
    The use of Betonleitwänden in road construction is known and offers many advantages over other restraint systems. The concrete guide walls are either in cast-in-situ construction, i. locally, for example, with the help of a slip formwork, made or assembled from prefabricated, mobile ready-mixed concrete elements on site or interconnected.
    It is particularly favorable when the Leitwandelemente the
    Concrete guide wall over long sections only rest on the ground. In a collision of a vehicle against the baffle Leitwandelemente can be moved together with adjacent, associated Leitwandelementen, so that the concrete baffle arched in the impact area arcuate outward. As a result, the impact energy can be reduced and the vehicle can be routed back to the roadway.
    Sectionwise or over longer distances, e.g. in the field of rigid obstacles, it may be advantageous, however, for the concrete guide wall or its guide wall elements to be connected in a stationary manner to the substrate. A connection between a stationary baffle element and an adjacent mobile, i. slidably resting on the ground, Leitwandelement a Betonleitwand is exposed to higher loads than a connection between two mobile baffle elements in a collision of a vehicle that bounces in the mobile section of the Betonleitwand. Because, unlike neighboring mobile baffle elements, the stationary
    Leitwandelement not with the adjacent mobile
    Can move along Leitwandelement, the transition point between the mobile and fixed baffle element acts as a Festeinspannung for the mobile baffle element. Therefore, particularly high forces and moments can occur at such a connection point.
    Such a transitional construction is known for example from EP 2 281 088 A. In this Hüllschuhe be used on the front pages to absorb the forces occurring. However, such Hüllschuhe are associated with the production of the Leitwandelemente with increased effort.
    The invention is therefore based on the object to provide a compound of the type mentioned available that withstands high loads and is easy to produce.
    This object is achieved according to the invention with a compound having the features of claim 1.
    Preferred and advantageous embodiments of the invention are subject of the dependent claims.
    According to the invention, it is provided that the first guide wall element and the second guide wall element are connected to one another via at least one second, form-fitting coupling horizontally spaced from the first positive-locking coupling.
    The two or more than two couplings interconnecting the baffle elements may be designed and arranged according to the requirements placed on the connection between the fixed baffle element and the mobile baffle element. The horizontal distance between the
    Couplings and the position of the individual couplings on the end faces have an effect on the forces acting on the individual couplings in the event of an impact forces.
    Couplings or connecting elements, as disclosed in EP 2 347 053 B1, are particularly preferably used in the invention. Other forms of couplings are of course also possible.
    Further details, features and advantages of the invention will become apparent from the following description with reference to the accompanying drawings, in which a preferred embodiment is shown. It shows:
    1 shows a view of a guide wall element of a connection according to the invention in the direction of the arrow of the arrow P shown in FIG. 3;
    2 is a plan view of one end of the baffle element,
    Fig. 3 is an isometric view of the invention
    Connection of two baffle elements, in which a concrete body of one of the baffle elements is shown transparent, and
    4 shows a side view of a connection according to the invention of two baffle elements with partially transparent concrete bodies.
    Fig. 1 shows a baffle element lf, lm of a compound 2 according to the invention with an elongated concrete body 3 in a directed to an end face 4 at one end El of the concrete body 3 view. The baffle element lf, lm is arranged with a bottom surface 5 on a substrate, not shown, or lies on this, and has a substantially to the bottom surface 5 parallel aligned top surface 6.
    The guide wall element lf, lm is wider in the region of the bottom surface 5 than in the region of the cover surface 6, so that the guide wall element lf, lm tapers in profile upwards.
    A side surface 7, which in the installation position of the guide wall element lf, lm faces in a roadway, has in the region of
    Bottom surface 5 an approximately vertical, lower portion 8 and in the region of the top surface 6 a sloping, upper portion 9. Between the lower region 8 and the upper region 9, a central region 10 is arranged, which is inclined more than the upper region 9. One of the roadway-side side surface 7 opposite side surface 11 has from the bottom portion 5 to the top portion 6 a constant inclination, which preferably corresponds to the inclination of the upper portion 9 of the other side surface 7. The profile of the illustrated embodiment is referred to as a "single-sided New Jersey profile".
    It is conceivable within the scope of the invention, an embodiment in which the lower portion 8 of the side surface 7 is also inclined or substantially no lower portion 8 is provided, and an embodiment in which both side surfaces 7, 11 are mirror-inverted, so that the guide wall element lf Also, other profile shapes of the baffle element lf, lm than those of a "New Jersey profile", for example a "step profile", are possible within the scope of the invention.
    At the one end El of the baffle element lf, lm a corresponding in shape and size of the end face 4 pressure plate 13 is connected to the concrete body 3. The pressure plate 13, for example, anchoring elements 14 which are connected to the pressure plate 13, in particular welded to this, be anchored in the baffle element lf, lm By the pressure plates 13 is in an impact of a vehicle and a subsequent displacement of the mobile baffle element lm of a baffle element on the subsequent
    Leitwandelement act pressure distributed over a large area, bringing the
    Danger of local damage or destruction of the
    Leitwandelemente, especially in the corner, can be reduced.
    On the pressure plate 13, a first coupling element 15 is arranged for a first coupling 16 and a second coupling element 17 for a second coupling 18, in particular welded, or positively received in a slot-shaped recess.
    In the illustrated embodiment, the couplings 16, 18 are designed as positive couplings with a substantially vertical longitudinal extent, preferably as the connecting elements described in EP 2 347 053 B1. Other shaped couplings or other types of couplings are also useful in the invention.
    The coupling elements 15, 17 are arranged in vertically extending recesses 19 and protrude only so far beyond the end face 4, that only a small gap is formed between the end faces 2 of two interconnected guide wall elements lf, lm.
    The first coupling element 15 is shown in the illustrated
    Embodiment arranged substantially centrally between the upper portion 9 of the road-side side surface 7 and the opposite side surface 11, whereas the second coupling member 17 thereof horizontally spaced and closer to the side surface 7, which faces the road, in particular near the central region 10 of the side surface. 7 , is arranged. The distance between the first coupling element 15 and thus the first coupling 16 to the adjacent side surface 11 is preferably greater than the distance of the second coupling element 17 and thus the second coupling 16 to the adjacent side surface 7th
    The first coupling element 15, and thus the first coupling 16, has a first length LI and the second coupling element 17, and thus the second coupling 18, a second length L2, wherein the first length LI is preferably greater than the second length L2. Although these aspect ratios are preferred because they ensure a stable connection of the baffle elements, other aspect ratios are possible. In particular, the lengths LI and L2 can be the same size, or the first coupling element 15 can be formed by two separate, superimposed coupling elements of any length.
    Furthermore, the first coupling element 15, and thus the first coupling 16, a first distance Al to the bottom surface 5 and the second coupling element 17, and thus the second coupling 18, a second distance A2 to the bottom surface 5, wherein the first distance Al preferably larger is the second distance A2. These distances Al, A2 but can also be different, especially the same size.
    In an embodiment not shown in the drawings with three couplings 16, 18, in which the guide wall element lf, lm, for example, a "double-sided New Jersey profile", a length of a third clutch is preferably as long as the length L2 of the second clutch 18th , and a distance of the third clutch to the bottom surface 5 is preferably as large as the second distance A2 of the second clutch 18 to the bottom surface 5, wherein in such an embodiment, the first clutch 16 is particularly preferably arranged symmetrically between the second clutch 18 and the third clutch ,
    Fig. 2 shows a plan view of the top surface 6 of
    Leitwandelements lf, lm with the arranged on the end face 4 pressure plate 13 and in the longitudinal direction of the Leitwandelementes lf, lm behind it extending concrete body 3rd
    The guide wall element lf, lm shown in FIGS. 1 and 2 can be both a stationary guide wall element lf and a mobile guide wall element lm, wherein a stationary guide wall element lf either substantially over the entire bottom surface 5 or only partially, for example via bottom anchoring elements, not shown firmly and essentially immovably connected to the ground can be.
    3 shows an isometric view of the connection 2 according to the invention of two baffle elements lf, lm, wherein the concrete body 3 of one of the baffle elements lf, lm is shown transparent.
    The guide wall elements lf, lm are as described via the couplings 16, 18 connected to each other, wherein the
    Coupling elements 15, 17 of the one end face 4 with the corresponding coupling elements 15, 17 of the other end face 4 are connected by the coupling elements 15, 17 of the mobile Leitwandelements lm are pushed from above into the coupling elements 15, 17 of the stationary Leitwandelements lf. The end faces 4 of the connected baffle elements lf, lm have preferably, but not necessarily, only a small distance from each other.
    At the back of the coupling elements 15, 17, the
    Facing concrete body, 18 rib-shaped, vertically extending webs 20 are integrally formed on the couplings 16, which protrude into the guide wall element lf, lm or in the concrete body 3 of the guide wall element lf, lm. At this webs 20 further anchoring elements 21 or tension rods 22 may be arranged, which are connected either to a reinforcement of the concrete body or the web / s 20 of the clutch / s 16,18 at the other end E2 of the respective concrete body.
    In the illustrated embodiment, the webs 20 are passed through the slot-shaped recesses of the pressure plate 13 and poured into the concrete body 3. In addition, the coupling elements 15, 17 may be welded to the pressure plate 13.
    Fig. 4 shows a side view of an inventive
    Connection 2 of two baffle elements lf, lm, wherein the arranged in the interior of the concrete body 3 components, such as the coupling elements 15, 17, the webs 20 and the
    Anchoring elements 21, shown in broken lines.
    The arranged in the middle of Fig. 4 mobile baffle element lm is connected on the right side or at one end of the El concrete body 3 with the stationary baffle element lf via the compound 2 according to the invention. On the left side or at the other end E2, the mobile baffle element lm is connected to a further mobile baffle element lm 'via a further connection 2', which is embodied differently from the connection 2 according to the invention and shown in FIG
    Embodiment only another coupling 23 with
    Coupling elements and webs 20 has. The connection between the mobile baffle elements lm and lm 'is preferably carried out as described and described in EP 2 347 053 A, but of course can be designed differently.
    Tension rods 22 connect the webs 20 of the coupling 16 of the mobile baffle element lm, which is assigned to the fixed baffle element lf, with the web 20 of the further coupling 23 of the mobile baffle element lm, which is assigned to the other mobile baffle element lm '.
    The reinforcement of the concrete body 3 is preferably made of stainless steel. This allows the concrete cover to have a smaller thickness, for example, of only 2 cm, than conventional ones
    Can have guide wall elements. As a result, concrete parts which may flake off the concrete body 3 due to a collision of a vehicle with the guide wall element lf, lm, have a lower mass, which in turn reduces the risk of injury from these detached concrete parts.
