专利说明:

The invention relates to a baffle element of a vehicle restraint system according to the preamble of claim 1.
Conventional baffle members include coupling members for coupling the baffle members together to form a continuous vehicle restraint system. The vehicle restraint system serves to restrain impacting vehicles, with the coupling member being adapted to be coupled to a coupling member of another baffle member to connect the individual baffle members to a continuous drawstring which, in the event of a crash of a vehicle against one of the baffle members, provides the impact energy to a larger number of baffle elements and thus prevents the vehicle from breaking through the vehicle restraint system.
In this case, coupling parts are known which have two different but opposite profiles, which can be put together to form a positive connection.
The disadvantage of this is that such coupling parts are cumbersome to handle. Furthermore, coupling parts are made of high quality materials, which is why elaborately designed, multi-part or massive coupling parts are disadvantageous.
The object of the invention is therefore to provide a baffle element of a vehicle restraint system of the type mentioned, with which the mentioned disadvantages can be avoided, which allows easy handling, record high tensile forces and can forward but is particularly simple and material-saving design.
This is achieved by the features of claim 1 according to the invention.
This results in the advantage that a baffle element can be formed which is easy to handle, since the baffle element can be coupled on both end faces regardless of its orientation and without intermediate pieces. This is advantageously formed by the shape of the coupling part of this particularly tensile and material-saving, since tensile forces occurring are divided evenly on both legs, and because even with an incipient deformation a positive connection between two coupling parts is still reliable.
The subclaims relate to further advantageous embodiments of the invention.
It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
The invention will be described in more detail with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. Showing:
Fig. 1 shows a first preferred embodiment of the baffle element as a section in plan view;
2 shows a second preferred embodiment of the baffle element as a section in plan view.
3 shows the first preferred embodiment of the baffle element in front view. and
Fig. 4 shows the first preferred embodiment of the baffle element in side view.
1 to 4 show preferred embodiments of a baffle element 1 of a vehicle restraint system comprising at least one coupling part 2 to connect a plurality of baffle elements 1 to a continuous drawstring.
The baffle element 1 is a part of a vehicle restraint system, wherein the baffle element 1 in particular as a finished part, preferably as a precast concrete part, may be formed, which is preferably prefabricated and then can be brought to the place of use. The baffle element 1 may be designed in particular for the arrangement next to a road or between two lanes.
The baffle element 1 has at least one coupling part 2, in particular in each case a coupling part 2 at the end faces, wherein the coupling part 2 is intended to be coupled with a coupling part 2 of another baffle element 1 to connect the individual baffle elements 6 to a continuous drawstring, which, in the event of an impact of a vehicle against one of the baffle elements 1, transmits the impact energy to a larger number of baffle elements 1 and thus prevents the vehicle from breaking through the vehicle restraint system. This continuous drawstring is claimed here mainly to train. The direction of this tensile stress, which can also be regarded as a predeterminable tensile direction, may preferably correspond to a longitudinal direction of the baffle element 1.
It is provided that the coupling part 2 has a, first width having a first leg 3 with a first hook extension 4 at a free end of the first leg 3, and a second leg 5 with a second hook extension 6 at a free end of the second leg 5 , The first width of the first leg 3 is in this case measured transversely to a longitudinal direction of the first leg 3 and to the intended pulling direction. The first width of the first leg 3 may in particular be the width of the first leg 3 just before the first hook extension 4.
The coupling part 2 may in particular be formed in one piece.
It is provided that the coupling part 2 can be coupled with a coupling part 2 which is identical to the coupling part 2, the first hook extension 4 abutting the second hook extension 6 of the further coupling part 2 in a first contact region 7 in a coupled state of the coupling parts 2, and the second Hook extension 6 in a second contact region 8 rests against the first hook extension 4 of the further coupling part 2. The coupling part 2 is therefore designed to be brought into engagement with an identically formed coupling part 2 of an adjacent guide wall element 1 for producing a coupled state between two guide wall elements 1, wherein the legs 3.5 of the two coupling parts 2 overlap in the region of the free ends , The first contact area 7 and the second contact area 8 are those areas or areas where the hook extensions 4, 6 are in contact with each other. The
In this case, contact areas 7, 8 may in particular be the areas of the hook extensions 4, 6 provided for mutual contact.
The hook extensions 4, 6 are particularly preferably directed in the same direction, as a result of which they can get caught in one another.
The legs 3, 5 can preferably be designed as a profile running perpendicularly in the operating position of the guide wall element 1, which profile can be displaced in the vertical direction relative to one another. The vertical in a baffle element 1 in the operating position can therefore also be regarded as a direction of displacement of the coupling parts 2.
The legs 3.5 can in particular form a u- or v-shaped profile.
It is further provided that on a side facing away from the first hook extension 4 side of the first leg 3, a sliding surface 9 is arranged, wherein in the coupled state, the sliding surface 9 a sliding surface 9 of the first leg 3 of the further coupling part 2 faces. Here, the legs 3.5 of a coupling part 2 form a receptacle for the first leg 3 of the other coupling part 2, wherein the second hook extension 6 of a coupling part 2 protrudes into this receptacle and such a positive connection with the first leg 3 of the other coupling part. 2 received. The side of the first leg 3 of the one coupling part 2 which faces away from the first hook extension 4 is in this case the side of the first leg 3 of the other coupling part 2 facing away from the first hook extension 4 and can contact these. Since the first leg 3 is intended to be received in the receptacle, the first leg 3 may also be referred to as an inner leg. The second leg 5, which is arranged in the coupled state on the outside, can also be considered as an outer leg. Due to the sliding surface 9 on this side facing away from the first leg 3 of the two coupling parts 2 coupled to each other entangled not form-fitting with each other, but can slide together. As a result, an occurring tensile force is essentially forwarded only via the intended contact regions 7, 8, as a result of which both thighs 3, 5 are subjected to tensile stress substantially uniformly. If the first leg 3 of the two coupling parts 2 coupled to one another would interlock with one another, ie would forward forces in the pulling direction in a form-fitting manner, the first legs 3 would absorb a significantly larger component of the pulling force than the second legs 5 and would thus have to be made substantially wider than the latter second leg 5.
The sliding surface 9 can be undercut here, in particular in the intended direction of pull. This means that viewed in the direction of the intended pulling direction, the sliding surface 9 has no undercut on which it could get caught. The sliding surface 9 can further be particularly flat.
Furthermore, it is provided that the measured in the pulling direction of the drawstring distance of the first contact portion 7 to the second contact portion 8 is smaller than the first width of the first leg 3. This results in the advantageous effect that even at a high tensile load of the connection of the two coupling parts 2, in which the hook extensions 4,6 already begin to deform, a reliable form fit is still given.
At a very high tensile load, a failure of the coupling part 2 takes place primarily by a deformation of the legs 3,5 and the hook extensions 4,6 before the tensile load is sufficient for a tearing of the legs 3,5. Here, a high tensile load and the forces occurring in the contact areas 7.8 ensures a force component which on the one hand tries to push apart the legs 3.5 and on the other hand aufzubiegen the hook extensions 4.6, the free ends of the legs 3.5 a bending moment are exposed.
The first leg 3 are pressed against each other when bending on the sliding surfaces 9 and can not dodge first, while the second legs 5 are bent to the outside. Therefore, it is advantageous to form the second legs 5 as solid as possible compared to the first leg 3, so that they can withstand the force bending them well. This is done on the one hand by the sliding surfaces 9, by which the force absorption in the pulling direction is divided substantially evenly on the two legs 3.5, whereby the first leg 3 can be made relatively slim.
Since the distance between the first contact region 7 and the second contact region 8 in the pulling direction is smaller than the first width of the first leg 3, the adjoining first legs 3 are pressed against one another in a region which is already reinforced by the hook extensions 4. Due to the bending of the first hook extensions 4, the introduction of force is greatest at an outermost contact point of the sliding surface 9 in the pulling direction, and since the two outermost contact points of the two first legs 3 are spaced apart, they exert a bending moment on the two legs 3 , If the distance between the two contact areas 7, 8 is low in the pulling direction, mutually exerted bending moments of the first legs 3 can be kept small. This can also be prevented that the first leg 3 are bent by a, caused by this pressing, bending moment, whereby the first leg 3 may also be formed comparatively slim.
As a result of the combination of these features, a coupling element 2 can be formed which can absorb even high tensile forces, wherein the inner first leg 3 is designed to be particularly slim compared to the outer second leg 5, whereby the second leg 5 absorbs the critical bending moments particularly well can.
This results in the advantage that a baffle element 1 can be formed which is easy to handle, since the baffle element 1 can be coupled on both end faces regardless of its orientation and without intermediate pieces. Here, in an advantageous manner by the shape of the coupling part 2 of this particularly tensile and material-saving, since tensile forces occurring evenly on both legs 3.5 are divided, and since even with an incipient deformation a positive connection is still given reliable.
Furthermore, a vehicle restraint system comprising a plurality of such baffle elements 1 is provided, wherein the baffle elements 1 are coupled together by means of the coupling parts 2. In FIGS. 1 and 2, two interconnected coupling parts 2 of adjacent baffle elements 1 are shown.
The baffle element 1 may in particular have a concrete body 10, which is intended to receive the impact pulse. The concrete body 10 may be made of concrete or a concrete mix. The concrete body 10 may in this case have a contact surface 11 on the underside. Furthermore, it can be provided that the concrete body 10 has a New Jersey profile or a step profile.
In the concrete body 10, a tension element 12 may be particularly preferably arranged, which tension element 12 may in particular extend continuously in the concrete body 10, and in the event of an impact should absorb the tensile forces acting on the concrete body 10. The at least one tension element 12 may be cast in the concrete body 10.
The at least one tension element 12 may in particular be made of metal, preferably of steel, in particular of reinforcing steel. Since the tension member 12 is protected by the concrete body 10 from environmental influences, the tension member 1 may be formed in particular free of a surface finish, such as a non-galvanized steel.
The at least one tension element 12 may in this case be a reinforcing rod or a reinforcing rope.
Furthermore, the at least one tension element 12 comprising plastic fibers, in particular aramid fiber, or carbon fibers can be formed.
The at least one tension element 12 may preferably be connected to at least one coupling part 2, in particular two coupling parts 2. In this case, the coupling parts 2 and the tension element 12 can in particular form that part of the guide wall element 1 which absorbs the tensile forces.
In Figs. 3 and 4, the arrangement according to the first embodiment of the coupling parts 2, the concrete body 10 and the tension member 12 is shown to each other, with hidden elements are shown in dashed lines.
It can preferably be provided that the coupling part 2 a
Verbindungsabschm'tt 13 has to connect the coupling part 2 with the tension element 12. At one end of the connecting portion, in particular both legs 3.5 may be formed. In particular, the connecting section can be arranged in a center plane of the guide wall element 2 running in the direction of pulling. As a result, the tensile forces can be passed on to the tension element 12 without causing bending moments within the concrete body 10.
The connection of the coupling part 2 to the tension member 12 can be varied, for example by welding, gluing or by positive locking.
It can preferably be provided that the guide wall element 1 has a coupling part 2 at both ends, with a coupling part 2 being particularly preferably arranged on a first end side and a second end side of the concrete body 10. Here, preferably, the coupling parts 2 protrude from the respective end wall of the concrete body 7.
The coupling parts 2 may in particular comprise a corrosion-resistant material, in particular a corrosion-resistant steel and / or a corrosion-resistant surface finish, preferably in the form of a galvanizing.
It can preferably be provided that the distance of the first contact region 7 to the second contact region 8 in the pulling direction of the tension band is smaller than one half, in particular a quarter, of the first width of the first leg 3. With a decreasing distance, the advantageous effect increases. that the first leg 3 abut against each other at their reinforced free ends.
Furthermore, it can be provided that a distance between the second hook extension 6 and the sliding surface 9 corresponds to a sum of the first width of the first leg 3 and a predetermined gap width. In order to connect or disconnect the two coupling parts 2 with each other, a certain play of the first legs 3 relative to each other is advantageous, which play can be formed as a gap between the two sliding surfaces 9. This gap is clearly visible in FIG. 2, for example. It is advantageous if this gap does not exceed a predefinable gap width, so that the first leg 3 can quickly abut each other in the event of deformation during an impact of a vehicle, whereby the deformation of the first leg 3 can be kept low at a large tensile load.
Particularly preferably, it may be provided that the predefinable gap width is smaller than 50%, in particular 30%, particularly preferably 10%, of the first width. In these gap widths a compact design is possible, with the first leg 3 can hardly deform.
Furthermore, it can be provided that the sliding surface 9 is arranged in a first plane, and that the first plane with respect to the pulling direction by 3 ° to 30 °, in particular 10 ° to 20 °, tilted. The tilting axis is in this case vertical, wherein the first plane is tilted in the direction of the first extension 4. As a result, even when the first leg 3 deforms, it can be achieved that the sliding surface 9 is not bent in such a way that an undercut is formed. Such a sliding surface 9 is shown in the embodiment in Fig. 1.
Alternatively, the sliding surface 9 is arranged in the first plane, wherein the first plane extends in the pulling direction. Such a sliding surface 9 is shown in the embodiment in Fig. 2.
Furthermore, it can preferably be provided that the sliding surface 9 is arranged substantially in an extension of a running in the pulling direction and vertical center plane of the baffle element 1.
Particularly preferably, it can be provided that the first hook extension 4 and / or the second hook extension 6 are formed undercut. The fact that the first hook extension 4 and / or the second hook extension 6 is formed undercut here means that the first hook extension 4 and / or the second hook extension 6 have at least one surface in the respective contact region 7, 8 which, the course of the respective hook extension 4, 6 in the direction of its free end following, at least one component against the pulling direction has. It can thereby be achieved that, in the case of a substantially deformation-free tensile load, only the contact regions 7, 8 are loaded and the first legs 3 are not pressed against one another on their sliding surfaces 9.
Alternatively, the first hook extension 4 and / or the second hook extension 6 in the respective contact region 7, 8 only have a surface which is normal to the pulling direction.
Preferably, it can further be provided that the first leg 3 has a substantially constant width from a projection to the free end. The approach of the first leg 3 may in this case be formed on the connecting portion 13. Since the first leg 3 transmits essentially only tensile forces in the pulling direction, it can have a material-saving shape with a constant width. This essentially a constant width corresponds to the first width.
The first width may in particular be between 5 mm and 20 mm, preferably between 10 mm and 15 mm.
In particular, it can be provided that the second leg 5 has a substantially constant width from a projection to the free end
Furthermore, it can be provided that the first hook extension 4 and / or the second hook extension 6 is formed as a bent end of the respective leg 3,5. In this case, a width of a hook extension 4, 6 corresponds to the width of the respective leg 3, 5. Thereby, the coupling part 2 can be easily formed.
It can preferably be provided that the second leg 5 is wider than the first leg 3. As a result, the second leg 5 can absorb the bending moments that occur particularly well when the second leg 5 is pressed outwards in the case of a very strong tensile load.
Furthermore, it can be provided that at least one reinforcing rib is formed on an outer side of the second leg 5. The reinforcing rib may be formed on the outside of the second leg 5 following the course of the second leg 5, in particular over the entire outer side. In particular, a width of the reinforcing rib may be 50% to 200% of the width of the second
Schenkels 5 amount. By the reinforcing rib, the resistance of the second leg 5 with respect to forces, which try to bend the second leg 5 to the outside, be increased with little material cost.
