Description

1

The invention relates to a concrete guard wall for a vehicle restraint system according to

claim 1.

It is known that vehicle restraint systems comprise several interconnected concrete barrier walls. These concrete guide walls usually form a continuous drawstring over long distances and are not interrupted, so that in the event of a vehicle impact, the impact energy can be distributed over a large area of the vehicle restraint system in order to prevent damage to the vehicle occupants. These, often massive, concrete guide walls can only be climbed by people in emergencies or for maintenance work. Even with climbing aids, a good physical condition is necessary to overcome such a concrete guide wall. However, in times of steadily increasing need for safety in road traffic, road operators require that, in particular in the case of noise barriers, but also in the vicinity of emergency telephones, passageways at ground level must be provided at certain intervals so that the roadway can be accessed in an emergency

to leave quickly and easily and to be able to call for help if necessary.

Any free breakthrough in a concrete barrier or a noise barrier, however, represents a weak point in the vehicle restraint system, as a result of which

whose retention effect can be greatly reduced.

One possibility of creating an opening between two concrete guide walls is that two rows of concrete guide walls are arranged at least partially overlapping and that an opening is formed in the area of the overlap. This means that, in the direction of the flowing traffic, a first row of concrete baffles is anchored with an end element in which the opening is arranged. Set back around the desired opening and overlapping by a certain length, there is a second row of concrete guide walls, starting from an initial element anchored in the ground. The second row is parallel to the opening and set back from the first row. In the area of the opening, the second row swings in and runs in the direction of the first row

continuously to the first row, especially following the course of the road.

2

The disadvantage of this is that such an offset opening can only be formed if sufficient space is available to be able to arrange two rows of concrete guide walls arranged offset. Furthermore, this solution is expensive and time-consuming to install due to the additional concrete guide walls required and the additional space required. The restraint effect of the vehicle restraint system is further enhanced by the opening that is not closed

reduced.

The object of the invention is therefore to provide a concrete baffle of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which a passage through the concrete baffle enables and furthermore a

high safety of vehicle occupants should be guaranteed. According to the invention, this is achieved by the features of claim 1.

This has the advantage that a passage through the concrete barrier can be provided without creating a safety risk for the flowing traffic. The access opening can be quickly opened and also closed again by means of the at least one predeterminable movable closure element. Since no further concrete guide walls are required to provide the access opening, the access opening is simple, space-saving and inexpensive to design. Since a reinforcement bridge is arranged at least in the closed state in an area of the access opening, the reinforcement bridge connecting the first reinforcement section and the second reinforcement section to form a continuous tension band, a weak point in the concrete guide wall is avoided, whereby the retention effect of the concrete guide wall is high and this can also absorb strong tensile loads. In other words, the continuous attachment tape significantly increases the resistance of the concrete guide wall to tensile forces compared to a concrete guide wall without a continuous tension tape. Since the concrete guide wall does not need to be anchored in the subsurface, it can be installed or set up quickly and easily without modifying the subsurface, for example by drilling holes or additional foundations

have to.

The invention further relates to a vehicle restraint system according to the

Claim 12.

The invention therefore also has the object of specifying a vehicle restraint system of the type mentioned at the beginning, with which a passage through the concrete guide wall enables and furthermore a high level of safety for vehicle occupants

should be granted. According to the invention, this is achieved by the features of claim 12.

The benefits of the vehicle restraint system are the same as the benefits of the above

called concrete baffle element. The subclaims relate to further advantageous embodiments of the invention.

Express reference is hereby made to the wording of the claims, whereby the claims are hereby incorporated by reference into the

Description are inserted and are considered to be reproduced verbatim.

If the at least one closure element is designed as a sliding door, the sliding door being displaceable in the direction of the longitudinal extension of the concrete guide wall, there is the advantage that the access opening can also be exposed by a person with little effort. Since, for example, no cover has to be lifted off and stowed away, there is less space required and there are no parts standing around on the roadway that could be

pose a considerable safety risk to traffic.

If the vehicle restraint system also has a noise protection wall, with a door being arranged in the area of the access opening in the noise protection wall, there is the advantage that there are no steel crash barriers in front of the door

are needed to achieve a good retention effect.

The invention is illustrated with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example,

described in more detail. It shows:

The access opening 3 can be quickly opened and also closed again by the at least one predeterminable movable closure element 5. Since no further concrete guide walls are required to provide the access opening 3, the access opening 3 is simple, space-saving and inexpensive to design. Since a reinforcement bridge 6 is arranged at least in the closed state in an area of the access opening 3, the reinforcement bridge 6 connecting the first reinforcement section 2 and the second reinforcement section 4 to one another to form a continuous tension band, a weak point in the concrete guide wall 1 is avoided, whereby the Retention effect of the concrete guide wall 1 is high and this can also absorb strong tensile loads. In other words, the resistance of the concrete guide wall 1 to tensile forces compared to a concrete guide wall without a continuous tension belt is significantly increased by the continuous attachment tape. Since the concrete guide wall 1 does not need to be anchored in the ground, it can be installed or set up quickly and easily without the ground through, for example, bores or additional holes

Having to modify foundations.

The concrete guide wall 1 can be arranged in particular next to a road or

Closure element 5 must be given the necessary restraint effect. It is provided that the closure element 5 can be moved in a predefinable manner.

At least in the closed state, a reinforcement bridging 6 is arranged in the area of the access opening 3. The reinforcement bridging 6 connects the first reinforcement section 2 and the second reinforcement section 4 to form a continuous tension band. Due to the interaction of the reinforcement bridging 6 with the first and second reinforcement sections 2, 4, at least in the closed state, a continuous tension band for the transmission of tensile forces via the essentially

This can result in improper stealing of the

Closure element 5 prevented or the probability that

the closure element 5 is stolen, can be greatly reduced. The fact that the closure element 5 is movably attached in the open state also reduces the risk that the closure element 5 inadvertently hits the

Carriageway where it would pose a safety risk.
