Description

The invention relates to a vehicle restraint system for limiting the route, which consists of juxtaposed Leitschwellen according to the features in the preamble of claim 1.

A vehicle restraint system counts, for example, by the DE 38 27 030 C2 to the state of the art. The vehicle restraint system is formed by a string of nested thresholds. Each barrier has a housing-like base body which can be erected on the floor and a guide rail arranged above the base body. In the known type, the guide rail and the base body are connected by means of posts profiled in a sigmoid shape in horizontal cross section. The Leitholme are welded to the post and coupled via guide brackets with these form-fitting. The lower ends of the posts are welded inside the base body. There are also Auführungsformen in which the posts are screwed via support plates and bolts on the base body.

A comparable vehicle restraint system with a further developed coupling device for connecting two guide rails describes the EP 1 418 274 A1 , Another modification of the vehicle restraint system for use on bridges goes from the DE 103 18 357 A1 out.

The known vehicle restraint system has basically proven itself in practice. It is used in particular in construction sites with greater risk, where a retention capacity up to the containment level H2 according to DIN 1317 is required.

The DE 38 20 930 A1 describes a roadway separating device which is formed by a number of basic body, which are formed as a solid body and are made for example of recycled plastic. The main body are lined up in their longitudinal direction and coupled together by means of a coupling device form-fitting manner so that they result in a coherent wall. On the series of basic body a number of attachment bodies can be placed so that the separator reaches a greater overall height. At the top of the body and at the bottom of the attachment body guide elements are included, by means of which the attachment body are guided on the body. The guide elements are formed at the top of the base body as a recess in the top and on the attachment bodies as a pin-like projections of the bottom. The attachment body can thereby be loosely placed on the body or firmly connected to these by means of fastening devices.

The DE 20 2007 015 012 U1 describes a protective wall assembly for limiting and securing lanes comprising weft-wise juxtaposed baffles with stiffened connection profiles, wherein the connection profile has a tubular base body, which in this case is arranged between two protective cheeks and is supported by these.

The US 7 144 188 describes a Leitschwellenstrang of three superimposed bodies. In the connection area is a toothing provided, via which engage the underside of a body with the respective top of a body arranged underneath. The bodies have two hollow chambers. In the vertical direction, the Leitschwellenkörper are additionally connected by a stiffening rod.

In the US 4,681,302 a barrier is described which has a plurality of barrier sections arranged one above the other. The barriers consist of plastic hollow bodies and engage in the connection area in a form-fitting manner.

The WO 93/12 300 describes a traffic partition wall consisting of base bodies and attachment bodies made of plastic, which engage in their connection area via corresponding fuse strips and securing grooves.

In practice, however, the requirement changes on a construction site again and again, for example, with the progress of a roadway rehabilitation. Consequently, conversion actions are relatively often necessary in which a lower containment vehicle restraint system must then be replaced by a higher containment vehicle restraint system, or vice versa.

For transport and assembly, it would be desirable for the barriers to be as manageable and light as possible. On the other hand, they should have a high retention capacity with a high resistance torque against transverse displacement in the planned use for limiting the route.

The invention is therefore based on the prior art based on the object to provide a transport and assembly technology improved vehicle restraint system with a high stability in the connection area between the base body and the threshold.

The solution to this problem is according to the invention in a vehicle restraint system according to claim 1.

The connection between the base body and resting on the base body guide bar is stabilized via a tongue and groove connection. For this purpose, the cover plate of the base body is designed as a spring, which is designed in the form of an extending in the longitudinal direction of the base body elevation in the middle of the cover plate. The guide rail has an open at its bottom C-shaped profile which extends in the longitudinal direction of the guide Holmes and is formed in the form of a groove. The remote from the web of Leitholms ends of the legs are preferably bent inwards. The spring of the base system and the groove of the Leitholms engage positively in each other and thereby ensure a stable connection that withstands both high bending moments, as well as a transverse displacement of the Leitholmes against the base body or vice versa counteracts.

The opposite the web angled legs of the Leitholmes are connected to each other in the region of their ends remote from the web via transverse webs, wherein the transverse webs are mounted at a distance from the spring.

In the context of the invention, it is possible to adapt the Leitschwellenstrang according to the requirements of individual sections by the base body is modularly increased by one or more Leitholme. The base body and a plurality of layers of Leitholmen can be in a so-called rotor association, that is offset from each other, be mounted, with an additional increase of the resistance torque is achieved here by the tongue and groove connection. The fixation of the guide rails via tension rods extending from the cover plate of the top Leitholmes to an abutment located in the base body. The guide bar and the base body can be easily and quickly coupled with each other via the tie rods. They can be mounted on the construction site.

The invention provides a flexible vehicle restraint system is created, whose base body assembled into a strand, basically independently, that is independent of the Leitholmen used can reach. Depending on the application or requirements on site, the base body and the upper guide rails can be supplemented to realize a higher degree of containment. This is particularly advantageous in construction sites, for example at construction site entrances with curvy route.

In the context of the invention, it is possible to first set up a Leitschwellenstrang, which consists only of the basic bodies. In the curve area or in principle on those sections where higher containment levels are required, the system is extended modularly around the upper guide rails. This is easily possible on site. A conversion actions or the replacement of a vehicle restraint system and replacement by another is not required.

Also transportingly the vehicle restraint system is advantageous because the base body and the guide rails can be transported separately. The base body as well as the Leitholme can be stacked well. As a result, the storage space available on a transport vehicle or a container can be used very well. The assembly takes place on site.

The coupling of the guide rails with the base bodies via tie rods. For this purpose, the tension rods are clamped to the abutment on the base body. This can be done for example by twisting the tie rod. The abutment is arranged within the base body.

In the context of the invention are used as tie rods in particular threaded rods used. The threaded rods have at least one rod portion with a thread, by means of which the threaded rod can be clamped in the arranged in the base body abutment. Preferably, it is an external thread, in particular a coarse thread. The abutment is equipped with a corresponding internal thread. By turning the threaded rod of the guide bar and the Base body pulled against each other and tightened. The tongue and groove connection facilitates the positioning of the guide Holmes on the base body. The actuation of the clamping or threaded rods takes place from the upper end. For this purpose, the threaded rods have a rod end on which a handle for rotating the threaded rod can be attached. Appropriately, the threaded rod passes through the upper end of the Leitholm. Due to the tongue and groove connection between the underside of the Leitholms and the top of the base body is an additional stabilizing guidance in the installation of the barriers.

Depending on the purpose and retention level and two superposed Leitholme can be provided. These can also be arranged to increase the drag torque in the rotor association.

Two longitudinally abutting base bodies are coupled according to claim 7 via a plug connection. Each base body has for this purpose on the one end face on an insertion pocket, which is provided with two vertical webs, by which the front-side baffle is spaced from the end face of the base body. On the second end face, the base body has an insertion tab formed by two vertical slots. When coupling two base body engages the Einstecklasche of a base body into the insertion pocket of the adjacent base body. The coupling of Leitholmen in the longitudinal direction can be carried out according to claim 9 via a similar plug connection. For this purpose, the guide rails are also provided on one end side with an insertion pocket and on the other end face with a push-in tab, which engage in the coupling for coupling.

FIG. 1 shows a first embodiment of a vehicle restraint system A according to the invention, which consists of at least one Leitschwelle 1. Details of the thresholds 1 are on hand FIGS. 1 to 10 described. Each barrier 1 has a floor-mounted housing-like base body 3 ( FIGS. 4 to 6 ) with inclined side Anfahrblechen 18, 19 and a top longitudinal edges 20, 21 of the Anfahrbleche 18, 19 connecting cover plate 8 and to the lower longitudinal edges 22, 23 of the Anfahrbleche 18, 19 from the base body 3 according to outwardly extending support plates 24, 25. The edge portions 26, 27 of the support plates 24, 25 are bent slightly downwards.

Directly on the cover plate 8 of the base body 3 at the threshold 1 each a Leitholm 2 ( FIGS. 7 and 8 ), which has a downwardly open C-shaped profile. The opening of the Leitholms 2 is defined by the angled ends of the legs 7. The opening of the Leitholms 2 thereby receives the shape of a groove 17. The legs 5 of the Leitholms 2 are connected by transverse webs 6 in the region of the groove 17, wherein the transverse webs 6 in have their center openings 43 for passing through the threaded rods 12 and at a distance s1 ( FIG. 3 ) are mounted to the spring 9. The cover plate 8 of the base body 3 is shaped in the longitudinal direction so that a spring 9 is formed, which fits into the groove 17 of the guide spar 2, or is matched in its width to the groove 17.

The Leitholme 2 and the base body 3 are releasably connected to each other via tie rods in the form of threaded rods 12. Here passes through each threaded rod 12 with an upper end 13 of the guide bar 2 through openings provided 30. In the cover plate 8 of the base body 3 coupling points 11 are provided for the passage of the threaded rods 12. At the coupling points 11, the threaded rods 12 are inserted into the base body 3 and can be clamped with a lower end 14 with a arranged in the base body 3 abutment 28. The threaded rods 12 have an external thread in the form of a coarse thread. The abutment 28 is formed by a in the lower third of a base body 3 transversely between the Anfahrblechen 18, 19 fixed abutment plate 16 and a angeordente below the abutment plate 16 nut 15.

For mounting the guide rails 2 on the base body 3, the threaded rods 12 are inserted through openings 30 in the webs 4 by the guide rails 2 in the base body 3 and clamped in the abutment 28 ( FIG. 12 ). This is done by turning the threaded rod 12 via one in the top End provided rod end 13 and thus suitable here not shown key surfaces, for example, a hexagon socket for attaching a handle is equipped. In the assembled state, the rod end 13 is flush with the surface of the web 4 or is sunk in this and is covered by a cap.

The individual thresholds can be assembled on site to the vehicle restraint system A. In this case, longitudinally abutting base body 3 as well as longitudinally abutting Leitholme 2 via connectors 31 (FIGS. FIG. 9 ), 32 ( FIG. 10 ) coupled. In principle, a strand of stacked base bodies 3 can also be erected first. This can be upgraded to the upper guide rails 2, if necessary, at higher risk locations, where a larger Aufhaltstufe is required. This is possible by means of the threaded rod 12 on site quickly and with relatively little installation effort. Each base body 3 has an insertion pocket 35 with its first end face 33 and an insertion tab 36 on the other second end face 34. The insertion pocket 35 is formed by a front-side impact plate 37, which is spaced from the first end face 33. The insertion tab 36 is formed between two vertical slots 38 in the second end face 34. For coupling the two base bodies 3, the insertion tab 36 of the one base body 3 is inserted into the insertion pocket 35 of the adjacent base body 3. In addition, a toothing in the connecting region between two base bodies 3 via pin-like projections 39 on the second end face 34 and a recess in the bottom piece 40 of the insertion pocket 33rd

The Leitschwellenstrang made of base bodies 3 meets at least the requirements of DIN 1317 with respect to the Anfahrversuchs TB 21 and thus the containment stage T1. To upgrade to the containment level H2 of the Leitschwellenstrang is extended and supplemented by upper guide rails 2. This will be a Guide bar 2 with its groove 17 placed on the spring 9 of the base body 3 and fixed by threaded rods 12.

The connector 32 between two longitudinally abutting Leitholmen 2 is in FIG. 10 shown. For this purpose, a guide rail 2 is provided on an end face 41 with an insertion pocket 45, whose front-side impact plate 46 is spaced by two vertical webs 44 with respect to the end face 41. The second end face 42 of the guide rail 2 has an insertion tab 48, which is formed by two vertical slots 47. With a coupling of two guide rails 2, the insertion tab 48 engages in the insertion pocket 45. This ensures a reliable coupling of the guide rails 2. In addition, a screw connection between the end faces 41, 42 of the guide rails 2 may be provided.

Also, the vehicle restraint system B, as in the FIGS. 11 and 12 Illustrates, has Leitschwellen 50 with base bodies 3 and Leitholmen 51, 52. With the base body 3, the upper guide rails 51, 52 coupled via threaded rods 12. In contrast to the embodiments described above, two superimposed guide rails 51, 52 are arranged in the vehicle restraint system B, which are braced by means of the threaded rods 12 with the base body 3. The bracing is done as before via an arranged in the base body 3 abutment 28, in which the threaded rods 12 are screwed. Also, the guide rails 51, 52 are configured C-shaped and arranged open at the bottom, wherein the side walls are connected by not visible here transverse webs analogous to the vehicle restraint system A. In the transverse webs openings for performing the threaded rod 12 are also provided. The guide rails 51, 52 can be mounted offset to the base body 3. In FIG. 11 are base body 3 and Leitholme 51, 52 connected to each other in Läuferverband.
