Definitions
- the invention relates to a post according to the preamble of patent claim 1.
- rockfall protection walls or rockfall protection nets in the vicinity of roadways in the country in order to avoid or reduce the risk of rockfall on vehicles or on the roadway.
- rockfall protection walls or rockfall protection nets in the vicinity of roadways in the country in order to avoid or reduce the risk of rockfall on vehicles or on the roadway.
- such an installation is usually very complex and time-consuming and is often only carried out after a rockfall or rockfall has occurred.
- the object of the invention is therefore to specify a post of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which operation on a secured road can be maintained after a rock fall.
- rockfall protection can be erected quickly and easily on an endangered or secured road and operations on this road can be maintained while the rock is being rehabilitated. If there are already concrete barrier elements on the secured road section, they can simply be removed and quickly modified using the posts and a rockfall protection fence can be easily attached to the posts. Otherwise, concrete barrier elements can be easily and quickly transported to the endangered road as prefabricated parts.
- the advantage is that the concrete barrier elements are compact and movable, and after the road has been cleared, the posts can be easily dismantled if desired.
- the safety for road users is additionally increased, since on the one hand the posts with the rockfall protection fences provide stone protection and on the other hand the concrete barrier elements reduce vehicles leaving the road or such accidents.
- the uprights in combination with the concrete barrier elements offer a secure hold for the rockfall protection fence and no complex anchoring for the uprights in the subsoil is necessary.
- the post can be permanently coupled to the concrete barrier element, erected preventively in potentially endangered sections, or erected temporarily after a rockfall until the rock has been repaired and the road is free again. As a result, the road affected by the rockfall or falling rocks does not have to be bypassed to a large extent.
- FIG. 1 shows a schematic illustration of a preferred embodiment of the post in front view
- Fig. 2 shows a schematic illustration of the preferred embodiment of the post in side view
- FIG. 3 shows a detail of a preferred embodiment of the vehicle restraint system in a perspective view
- FIG. 4 shows a schematic view of a preferred embodiment of the vehicle restraint system with end elements in side view
- FIG. 5 shows a schematic view of a preferred embodiment of the vehicle restraint system with end elements in plan view.
- FIG. 1 to 5 show at least parts of a preferred embodiment of a post 1 for a rockfall protection fence 2, the post 1 having a coupling device 4 at a lower end region 3 for coupling the post 1 to at least one concrete barrier element 5.
- the safety for road users is additionally increased, since on the one hand the posts 1 with the stone chip protection fences 2 provide stone protection and on the other hand the concrete barrier elements 5 prevent vehicles from leaving the road or such accidents are reduced.
- the uprights 1 in combination with the concrete barrier elements 5 offer a secure hold for the rockfall protection fence 2 and no complex anchoring for the Stand 1 in the underground is necessary.
- the post 1 can be permanently coupled to the concrete guide wall element 5, erected preventively in potentially endangered sections, or erected temporarily after a rockfall until the rock has been rehabilitated and the road is released again. As a result, the road affected by the rockfall or falling rocks does not have to be bypassed to a large extent.
- the rockfall protection fence 2 is an obstacle or a demarcation which is intended to prevent rockfall on the roadway.
- the rockfall protection fence can have 2 meshes with continuous openings and are preferably made of metal.
- the rockfall protection fence 2 can also be closed, designed as a protective wall.
- the rockfall protection fence 2 can preferably comprise a wire mesh.
- the rockfall protection fence 2 can also include plastic and/or wood.
- the lower end area 3 is that area which adjoins that end which faces the ground in an assembled state.
- the post 1 is designed in such a way that it can be detached from the concrete guide wall element 5 without the use of tools.
- the coupling device 4 can particularly preferably have a receptacle for an extension of the concrete guide wall element 5 .
- the coupling device 4 has an extension, which in an assembled state in a recording, in particular Depression, the concrete guide wall element 5 engages.
- the coupling device 4 is designed for coupling the post 1 to two concrete guide wall elements 5 .
- two concrete guide wall elements 5 can be coupled to one another in a simple manner by means of the coupling device 4 .
- a chain of concrete barrier elements 5 can be produced by means of the post 1. Complicated couplings between the concrete barrier elements 5 are eliminated and the post 1 is pinched, so to speak, between two concrete barrier elements 5 in an assembled state and is therefore particularly stably attached or coupled to the concrete barrier elements 5 .
- the coupling device 4 has two receptacles for extensions of the concrete guide wall elements 5 .
- the coupling device 4 has two extensions which engage in recesses of the concrete guide wall elements 5 in the assembled state.
- the coupling device 4 can have an extension and a recess for coupling two concrete guide wall elements 5 .
- the coupling device 4 For reasons of stability and for reasons of simple manufacture, provision can be made for the coupling device 4 to be designed in one piece.
- the upper area 6 is arranged above the at least one concrete guide wall element 5 .
- the upper region 6 is essentially at least twice as long, in particular at least three times as long, preferably at least five times as long as the lower end region 3 is.
- a closed side of the I-beam faces the roadway.
- the at least one fastening device 7 can be a receptacle.
- the at least one fastening device 7 can in particular be a loop for the rockfall protection fence 2 .
- the at least one fastening device 7 can also be a guide for the rockfall protection fence 2 .
- the at least one fastening device 7 can preferably be a shackle.
- the post 1 can have at least one support surface 8 above the coupling device 4 for supporting the post 1 on the at least one concrete guide wall element 5 .
- the angle of the at least one sloping surface is adapted to a contact surface of the concrete safety barrier element 5 in order to achieve a flat contact of the sloping surface on the concrete safety barrier element 5 .
- the supporting surface 8 has at least two opposite inclined surfaces for contacting at least two concrete guide wall elements 5 .
- the support surface 8 is essentially V-shaped, as shown in FIG. 1 by way of example.
- the post 1 is self-centering in an assembled state or in a state coupled to two concrete barrier elements 5 .
- a vehicle restraint system 9 comprising at least one concrete barrier element 5 and at least one post 1 coupled to the concrete barrier element 5 is provided.
- the two adjacent concrete guide wall elements 5 are only coupled to one another with the coupling device 4 of the post 1 .
- the upright 1 thus replaces the otherwise usual coupling of the concrete barrier elements 5, as a result of which the coupling of the upright 1 to the concrete barrier elements 5 is particularly simple.
- a vehicle restraint system 9 comprising several concrete barrier elements 5 can be set up particularly quickly.
- the vehicle restraint system 9 can also be dismantled particularly quickly by means of the uprights.
- the coupling device 4 is preferably arranged between the two adjacent concrete barrier elements 5 .
- a chain with the sequence of concrete barrier elements 5 and uprights 1 arranged after a concrete barrier element 5 can be produced, which is shown by way of example in FIG. 3 .
- the concrete guide wall elements 5 have counter-coupling parts and that the posts 1 are coupled to the counter-coupling parts by means of their coupling devices 4, whereby a particularly stable coupling is achieved.
- the counter-coupling parts can preferably consist of metal.
- the coupling devices 4 can engage in particular in the counter-coupling parts for coupling.
- the counter-coupling part can preferably have at least one receptacle and the coupling device 4 can have at least one extension, which engages in the receptacle in the coupled state.
- the counter-coupling part has the shape of a C-profile and that the coupling device 4 has at least one extension which engages in the counter-coupling part in the coupled state.
- the coupling device 4 has at least two extensions and is essentially T-shaped.
- the anchoring is arranged on the counter-coupling part and extends into the concrete body of the concrete guide wall element 5 .
- the anchorage can be designed, for example, in the form of a rod and/or hook and/or loop.
- the counter-coupling part can be anchored in the concrete guide wall element 5 in a stable manner.
- anchorages of opposing counter-coupling parts of a concrete barrier element 5 are not connected to one another, ie do not represent a tie rod.
- the drawstring is formed in particular by two mutually opposite counter-coupling parts and a tension element connected or fastened to these counter-coupling parts, in particular in the form of at least one rod or at least one plate.
- the individual concrete barrier elements 5 are coupled by means of the uprights 1 to form a continuous drawstring.
- the energy absorbed by the rockfall protection fence 2 can be divided or forwarded via the uprights 1 to the tie rods of the concrete guide wall elements 5 .
- the concrete guide wall element 5 can preferably be prefabricated. One or more concrete barrier elements 5 can be transported to the endangered road section and erected. The concrete guide wall elements 5 can also be manufactured on site. The concrete guide wall elements 5 can be coupled to one another by means of the uprights 1 . Finally, the rockfall protection fence 2 is attached to the posts 1.
- the concrete barrier elements 5 have reinforcement that is essentially close to the surface.
- the near-surface reinforcement Textile grid included.
- the concrete guide wall elements 5 have fibers, in particular in the form of glass and/or carbon fiber mats. As a result, the spalling of concrete pieces from the surface of the concrete barrier elements 5 is avoided or reduced, whereby the durability of the concrete barrier elements 5 is increased.
- one or more end elements 10 are arranged on at least one, preferably on both, ends or end regions of the vehicle restraint system 9 .
- These end elements 10 are preferably concrete barrier elements 5.
