Abstract

The invention relates to a safety system with at least two movable, adjacently arranged concrete barriers and a composite means, via which the concrete barriers are connected or connectable.

Description

The invention relates to a safety system with at least two movable, adjacent concrete locks.

Movable concrete barriers are e.g. used for the defense against terror at temporary events, for example, to secure folk festivals, Christmas, Christmas or winter markets, sporting events, parades, carnival trains or concerts.

The concrete barriers block access routes, for example, to prevent trucks from entering the grounds and injuring or even killing people.

Since usually residual concrete is used, the concrete barriers can be produced comparatively inexpensively.

Often the concrete barriers are several hundred kilograms heavy. However, since a truck brings with it a multiple of weight and in case of emergency, if necessary, hits the concrete barriers at a higher speed, the concrete barriers brake the truck only inadequately. This has also shown tests. The truck breaks through the concrete barriers by pushing them to the side and thus reaches the actually protected terrain.

It is therefore an object of the invention to provide a safety system which prevents or at least makes it difficult to break through heavy vehicles.

The solution of this object is achieved by a security system having the features of claim 1.

According to the invention, the security system comprises a composite means by which the concrete barriers are connected or connectable.

The connection requires a vehicle to overcome the static friction and sliding friction of all interconnected concrete barriers. Since the weight of all concrete barriers is pulled along by the vehicle, this is slowed down quickly.

The composite ensures that the security system prevents or at least makes it difficult to break through heavy vehicles, in particular lorries.

Due to the fact that the concrete barriers are connected to each other, individual concrete barriers are also not shot like a billiard ball into the terrain to be protected after a collision with a vehicle, as is often the case without composite material. Dangers that emanate from the concrete barriers themselves can therefore be minimized.

In particular, another composite means may be provided to provide a concrete barrier with a solid component, e.g. a wall, a pole, a ground anchor or a tree. In this way, a lateral break through a plurality of juxtaposed and interconnected concrete barriers can be prevented.

The concrete barriers themselves are movable and in particular not firmly anchored to the ground. In this way, the concrete barriers are portable and can be used on mobile sites. Temporary events can be secured by this.

The concrete barriers may be of various sizes, weights and / or shapes. The properties of the concrete barriers can be selected according to the respective requirements.

For example, a concrete barrier may be formed as a cuboid. The dimension can e.g. 60cm x 60cm x 60cm (length x width x height), 90cm x 60cm x 60cm, 120cm x 60cm x 60cm or 180cm x 60cm x 60cm. The height or width may also be e.g. 80 cm or 90 cm.

In particular, the weight of a concrete barrier may be at least 0.5 tons, 1.0 tons, 1.5 tons, 2.0 tons or 2.5 tons. The higher the weight, the better the protection against vehicles. In particular, they are not heavier than 3.0 tons, 2.75 tons or 2.5 tons to enable a good transportability of the concrete barriers. For example, a concrete barrier may have a weight of 2.4 tons.

Also cylindrical, hemispherical, conical, pyramidal, tetrahedral, three-dimensional trapezoidal and / or panzersperrenförmige concrete barriers are possible.

The concrete barrier may also be formed as a concrete slab, which is loaded by a weight. As weight, e.g. serve a concrete block or a filled container. The container may be filled, for example, with sand, stones and / or water. In particular, the container can also be filled only at the place of use, whereby the transport is facilitated.

Between normal solid concrete barriers can thus, in particular at regular intervals, highly loaded concrete slabs in the Security system to be involved. Since a high weight load acts on the surface of the concrete slab, this results in a very large amount of static friction.

The top of the concrete barrier may be smooth or have nubs. If the concrete barrier has pimples, several concrete barriers can be stacked on top of each other like building bricks and the overall weight increased.

At the top, an eye or a hook may be provided to place the concrete barrier at the desired position.

Alternatively or additionally, the concrete barrier at the bottom can have recesses for forks of a stacker. In particular, the recesses may extend longitudinally and / or be oriented parallel to one another.

The bottom may also have a friction-enhanced structure, e.g. a corrugation, and / or have a friction material.

For example, the concrete barrier at the bottom may be an elastomer, e.g. a gum. The friction coefficient is increased in this way. This increases both the static friction and the sliding friction between the concrete barrier and the asphalt.

The distance between two concrete barriers may, for example, not exceed 0.5 m, 0.75 m, 1.0 m, 1.25 m, 1.5 m, 1.6 m, 1.7 m, 1.75 m, 1, 80 m, 1.85 m, 1.9 m, 1.95 m or 2.0 m. The smaller the distance, the harder a vehicle can break through the safety system.

In particular, the distance between the concrete barriers may be at least 0.5 m, 0.75 m, 1.0 m, 1.25 m or 1.5 m. Pedestrians can easily walk between the concrete barriers in this way.

Further developments of the invention can be found in the dependent claims, the description and the accompanying drawings.

According to one embodiment, the composite is flexible. The composite is thus not rigid, but movable. An adaptation to the local conditions is guaranteed. Also, the concrete barriers do not have to be aligned exactly with each other because the flexible composite has a certain tolerance, unlike a rigid composite.

According to a further embodiment, the composite means comprises a rope, in particular steel rope, or a chain. The material and the dimensions are preferably chosen such that the composite withstands a collision with a vehicle and does not break off.

The concrete barriers thus remain in a collision in the composite. The vehicle therefore always counteracts the total weight of all concrete barriers. Furthermore, individual concrete barriers do not dissolve and so are themselves not to deadly bullets.

According to a further embodiment, the concrete barriers in a lower region are connected or connectable. The composite extends in this way, especially on the ground. Pedestrians are therefore not hampered by the composite when passing the concrete barriers and can easily pass between the concrete barriers.

According to a further embodiment, the security system has a cable bridge. In particular, the cable bridge is laid over the composite on the floor.

Preferably, the cable bridge may have a trapezoidal, triangular or circular segment-shaped cross section. On the underside, a recess may be provided for the composite.

The risk of pedestrians stumbling over the composite is reduced by the cable bridge.

According to a further embodiment, the concrete barrier has at least one, preferably two, three or four fastening means for the composite. The composite may in particular be releasably connected to the concrete barrier.

In particular, the composite can only be fastened to the concrete barrier at the place of use via the fastening device. The transport is facilitated.

The concrete barrier preferably has a fastening device at least on two opposite sides. Thus, the concrete barrier can e.g. be connected on both sides with another concrete barrier or a solid component.

In the case of several fastening devices, these are provided in particular on different sides of the concrete barrier. If, for example, a fastening device is provided on each side in the case of a block-shaped concrete barrier, it is not necessary to pay attention to the orientation of the concrete barrier, since the composite can be fastened on each side.

According to a further embodiment, the fastening device comprises an eye or a hook, in particular made of metal, preferably steel. The composite can be easily attached to the eye or the hook.

In particular, the eyelet or the hook can be arranged on a threaded rod. The threaded rod may preferably have an external thread. About the threaded rod, the eye or the hook can be attached to the body of the concrete barrier.

According to a further embodiment, the fastening device comprises a sleeve. The sleeve can preferably be embedded in concrete during the production of the concrete barrier. Alternatively, a recess for the sleeve can be subsequently introduced into the concrete barrier. Conventional concrete barriers can be retrofitted in this way.

The sleeve is preferably arranged in a lower region of the concrete barrier. In particular, the sleeve has an internal thread. A threaded rod to which an eyelet or a hook is attached can be received in this way in the sleeve. The threaded rod is here screwed into the sleeve and is thus firmly connected to the body of the concrete barrier.

According to a further embodiment, a fixing device is provided for fixing the composite means to the fastening device. In particular, the composite is releasably fixed to the fastening device.

The fixing device may in particular be made of metal, preferably steel.

The composite, e.g. a steel cable or a chain, can be easily attached to the eyelet or hook by the fixing device.

According to a further embodiment, the fixing device comprises a carabiner, a shackle or a lock.

A carabiner has the advantage that the connection between the concrete barriers can be quickly solved if necessary, which is e.g. facilitates the dismantling.

A shackle is particularly suitable for transmitting large forces.

On the other hand, a lock provides protection against unauthorized release of the connection between the composite and the concrete barrier. The lock can e.g. be designed as a padlock. This can be opened in particular by means of a key or a numerical code.

According to a further embodiment, at least three, in particular at least four, five, six, seven or eight, concrete barriers are provided. In each case adjacent concrete barriers are in particular connected or connectable.

The more concrete barriers are connected to each other, the greater is the adhesion or sliding friction counteracting a vehicle.

Preferably, all fixing devices can be opened with the same key or numerical code.

All aspects, embodiments and features of the invention described herein can be combined with each other, in particular also detached from the specific embodiment in the context of which they are mentioned. In particular, all subject matters of the dependent claims may be combined with each other and with each subject matter of the independent claims.
