Abstract

A restraining rod has solid wooden elements (22,24) linked in sections to reinforcing safety belts (50 2,50 3) partly held in the wooden elements, which have a retaining slot that runs in a longitudinal direction and opens orthogonally to the longitudinal direction near the underside of the wooden elements.

Description

The present invention relates to a vehicle restraint system for securing a roadway having at least one longitudinally extending restraint string and a plurality of posts supporting the restraint strand at a predetermined mounting height above a ground, the restraint strand comprising at least one solid wood element and at least one at least partially connected thereto Armierungsgurt and wherein the reinforcing belt is at least partially received in the wood element.

Such a vehicle restraint system is known, for example, from the prior art according to the specification "GLISSIÈRE DE SÉCURITÉ MIXTE MÉTAL-BOIS", CIRCULAIRE D 'AGRÉMENT N ° 92-58 DU 5 OCTOBRE 1992 (filed with the application documents for the official file). This specification shows in Figures 6 and 7 each have a wooden element which is formed on its side facing away from the roadway back with a milled groove. In this groove, a U-shaped reinforcing belt is used, which can be fastened via connecting struts both on post elements and on an adjacent wooden element Armierungsgurt assembly.

However, it has been found that such an arrangement is not easy to handle in practice. In particular, such a vehicle restraint system is supplied with preassembled Holzelement-Armierungsgurt assemblies, which makes it harder at the installation site to customize the individual wood element Armierungsgurt assemblies to the particular installation situation. However, if an assembly of wood elements and Armierungsgurten only on site, that is at the installation site, so this is relatively expensive, especially because several people are required to hold the wood elements during assembly to the Armierungsgurte so that both components together can be screwed. Furthermore, it has been shown that a complete installation on site also cause problems because the wood elements have relatively low dimensional accuracy. This is due in particular to the fact that the wood "works" with time, that is, can deform due to drying processes and temperature influences. As a result, posts that have already been installed at the place of installation can no longer fit the wooden elements, so that the assembly is delayed and made more difficult by the need for adaptation to the individual components.

Furthermore, it is off US 5,462,258 a vehicle restraint system with wood elements known in which the Armierungsgurt is screwed to the groove-free back of the wood elements. Also, this vehicle restraint system is subject to the above-described problems during assembly, in particular with regard to the dimensional accuracy of the wood elements.

Out FR 2 633 319 B2 a vehicle restraint system with wood elements is known, in which the wood elements is provided in a connecting region to a respective post with metal profiles. The metal profiles serve on the one hand to reinforce the joint and on the other hand to connect two successive wooden elements. However, between the junctions, the wood elements are not reinforced, so that they can break completely in the event of an impact and therefore have only a very low vehicle retention.

Finally is off EP 0 924 346 A2 a vehicle restraint system is known in which the wood elements are divided in the longitudinal direction and provided with a textile insert. Furthermore, they rest on holding shells for coupling with the posts. This arrangement is relatively expensive to produce.

It is an object of the present invention to provide a vehicle restraint system of the type described, which allows a cost-effective production of a simple and easily adapted to the respective installation situation mounting.

This object is achieved by a vehicle restraint system of the type described, in which the at least one wood element is formed with a longitudinally extending receiving slot which opens orthogonal to the longitudinal direction in the region of the underside of the wood element and is dimensioned such that it during assembly the Armierungsgurt receives, so that the wood element rests on the at least one Armierungsgurt.

By attaching the receiving slot according to the invention, it is initially possible to ram the post elements to measure in the ground during assembly of the vehicle restraint system at the installation site and then attach the dimensionally reinforcing belt to the post elements. Then individual wooden elements can be pushed onto the Armierungsgurt, wherein the respective receiving slot of a wooden element receives the Armierungsgurt. As a result, the wooden element is already on the Armierungsgurt due to gravity and needs not to be kept further by a mechanic. Further assembly steps, such as the attachment of mounting screws, can then be easily done without major human effort. According to the invention thus the problem of deformation of the individual wood elements is thus avoided, since the posts are bolted only with the Armierungsgurten and deforestation underlying wood elements are postponed until after the Armierungsgurte. It is understood that the wood elements are manufactured with sufficient tolerances in order to be able to be postponed after a deformation easily between two post elements on the respective Armierungsgurt.

A development of the invention provides that the reinforcement belt is formed by a longitudinal profile, preferably a steel strip. As a result, a sufficient retention capacity of the vehicle restraint system can also be achieved. In particular, containment levels up to H2 according to DIN EN 1317-2 can be achieved, which is a very high value for a vehicle restraint system with wood elements.

Furthermore, it can be provided according to the invention that the wood element is formed like a trunk, wherein the receiving slot in which the wood element is arranged eccentrically. The eccentric arrangement of the receiving slot in the wooden element means that the slot is oriented, for example, after installation of the vehicle restraint system so that it runs parallel to a vertical center plane of the trunk-like wooden element and the back of the wooden element, that is away from the roadway, offset.

A development of the invention provides that at least one profile element is provided for the connection of the retaining strand and posts or / and for connecting two successive wooden elements, which can be fastened to the Armierungsgurt. For attachment serve preferably connecting screws. The profile element thus serves to connect two successive wooden elements and possibly also to connect the retaining strand with the post. Thus, it is possible not to couple the retaining strand at each juncture of two successive wooden elements with a post, but for example only every two or three joints. If higher containment levels have to be achieved, however, posts are attached to each juncture of two successive wooden elements.

An advantageous development of the invention provides that the wood element has at least end-side recess areas, wherein the profile element is arranged in the recess area. This makes it possible to accommodate the profile elements within the contour of the wood elements, so as to reduce the required space of the vehicle restraint system. With regard to the attachment of posts and profile element, a development of the invention provides that the profile element is designed as a C-profile with successive directed C-legs and that for fastening to the post member a C-leg hintergeifende mounting plate is provided. This has the advantage that the mounting plate can be moved along the entire profile element and so a simple adjustment of the retaining strand is already possible to measure rammed into the ground post. Also by this measure, deformations of the retaining strand during assembly can be readily compensated, so that an additional drilling of mounting holes, as may be required in individual solutions from the prior art due to the deformations, is no longer necessary.

In order to ensure that the retaining strand holds in an impact substantially the mounting height and is not pulled down by a bent post to the ground, a development of the invention provides that the mounting plate is connected by means of a breakaway head screw with the post element or connectable. With sufficiently high impact forces, the head of the breakaway head screw loosens from the shaft, so that the restraining strand separates from the post element and is held by adjacent post elements substantially in the mounting height. An impacting vehicle can not easily slide over the vehicle restraint system.

Conventional vehicle restraint systems with wood elements are often subject to the problem that they are difficult to adapt to curve paths of the roadway the course of the road. This is due, in particular, to the fact that the connecting regions of successive wooden elements are designed for a substantially rectilinear road course and must be deformed in a special way for adaptation to a curved roadway course. Such deformation often occurs improperly during assembly and leads to a reduction of the stoppage of the vehicle restraint system. A development of the invention takes this problem into account by providing that the profiled element has at least one incision region which allows a bending deformation of the profiled element about a bending axis orthogonal to the longitudinal direction. So it is possible, especially for Provide curved areas provided profile elements with notch area, which facilitate bending deformation of the profile element and thus allow adjustment of the vehicle restraint system to a curvy road course with little effort. Such profile elements allow a deformation both for adaptation to a concave and a convex curve.

To stabilize the post can be provided that this is provided with a longitudinal groove into which a reinforcement profile can be used.

A further development of the invention provides that the reinforcing belt can be connected to the wood element by means of at least one connecting bolt, wherein the connecting bolt passes through the wood element and the reinforcing belt. In order to take into account the possible deformations of the wood element in this context, can also be provided that the Armierungsgurt for receiving the connecting screw has a slot.

In a further embodiment of the invention it is provided that the connecting screw for connecting the Armierungsgurts with the wood element at the same time serves for the connection of profile element and Armierungsgurt. This makes it possible to further simplify the construction. If appropriate, a spacer, for example a U-washer, can be inserted between the wooden element and the reinforcing belt in order to ensure a sufficient clamping between the profile element and the reinforcing belt.

1, a vehicle restraint system according to the invention is shown in front view and generally designated 10. This comprises a along a longitudinal axis A extending in the longitudinal direction retaining strand 12, which is held by means of posts 14 and 16 at a predetermined mounting height H above a substrate U. It can be seen that the section of the retaining strand 12 shown in FIG. 1 is composed of several wooden elements 18, 20, 22 and 24 in a jerky manner. The posts 14 and 16 are attached to joints 26 and 28 at which two successive wooden elements 18 and 20 or 22 and 24 are interconnected in the following to be explained in detail. At a joint 30, however, the two consecutive wooden elements 20 and 22 are connected directly without additional posts. FIGS. 2 and 3 show a side view and a top view of the vehicle restraint system 10 according to FIG.

4 to 6, the post element 20 is shown in detail in various views by way of example. It can be seen that the post element 20 is formed in the longitudinal direction with an eccentrically arranged receiving slot 32. This receiving slot 32 extends, as shown in Figure 5, in a substantially vertical direction and thus opens orthogonal to the longitudinal direction of the wood element in the region of its bottom 34. The eccentricity is a distance d of the receiving slot from a substantially vertical center plane of the wood element 20 determined. This offset distance d is, for example, in the range of 2 to 3 cm. The receiving slot has a base 36 which delimits upward in it.

Furthermore, the wooden element 20 has end-side recessed areas 38 and 40, into which the receiving slot opens at the front. These recessed areas 38 and 40 are used to accommodate later explained in more detail profile elements, which then serve to connect two successive wooden elements or for attachment of the retaining strand 12 to posts. Further, in the wood element 20 connecting holes 42, 44 are provided, which are each formed at the opening portions with depressions 46. The connection bores 42 and 44 are substantially horizontal and orthogonal to the receiving slot 32.

FIG. 7 shows, in a reduced representation, a reinforcing belt 50, which is designed as a steel strip with a substantially rectangular cross section. The reinforcing belt 50 is dimensioned so that it fits into the receiving slot 32 with sufficient play. It has a series of mounting holes 52 and further has two connecting holes 54 and 56. The connecting holes 54 and 56 are formed as slots and correspond to the connecting holes 42 and 44 in the wood element 20, so that by inserting a connecting screw wood element 20 and Armierungsgurt 50 tightly screw together. Possible deformations of the wood element 20 can be compensated over the slots. The mounting holes 52 are used to connect two Armierungsgurte together, as will be explained in more detail below.

8 now shows the joint 30 in an axis-containing vertical section in detail view. At this joint 30, the two wooden elements 20 and 22 abut each other. It can be seen that the wooden element 20 has received a reinforcing belt 50 ₁ and the wooden element 22 has received a reinforcing belt 50 ₂ in the respective receiving slot 32 ₁ and 32 ₂ . The two Armierungsgurte 50 ₁ and 50 ₂ each protrude into the recess portion 40 of the wood element 20 and 38 of the wood element 22 into it. The Armierungsgurte 50 ₁ and 50 ₂ are firmly screwed via connecting screws 58 and 60 with the wood elements 20 and 22, wherein the screw heads and the associated nuts are each received in the depressions 46.

For fixing the two wooden elements 20 and 22 together, a C-profile element 62, which is shown in Figure 9 in section. The C-profile element 62 overlaps with the two ends of Armierungsgurte 50 ₁ and 50 ₂ and is connected by fastening screws 64 with these. The fastening screws 64 pass through the fastening bores 52 shown in FIG. 7 in the reinforcing belts 50 ₁ and 50 ₂ . One recognizes this also in Fig.9. By this type of attachment can be a particularly against tensile loads, relatively stable jerky composite restraint string 12 assemble.

Fig.10 shows the joint area 28 at which the two wood elements 22 and 24 abut each other. This joint region 28 is formed in the same manner as the joint region 30, that is, the two Armierungsgurte 50 ₂ and 50 ₃ , which are respectively received in the wood element 22 and 24, are on the C-profile element 62 and associated connecting screws 64th screwed together as described with reference to Fig.8 and 9. Further, the C-profile member 62 is connected to the post 16, as will be explained in detail below. It can be seen that the post 16 is reinforced with a reinforcing profile 66, which is received in a longitudinal groove 68 on the back of the post 16. For fixing the C-profile element 62 to the post 16 is a predetermined breaking screw 70. It can be seen in Figure 11, that the predetermined breaking screw is inserted into a mounting plate 72 which engages behind facing leg portions of the C-profile element 62. Figures 12 and 13 show this in detail. The mounting plate 72 has a slot 74 into which the fastening screw 70 is inserted and within which it is displaceable. The fixing plate 72 engages behind the two mutually facing leg sections 76 and 78. The predetermined breaking screw 70 has near its head a circumferential recess 80 which acts as a predetermined breaking point and from a certain load, a detachment of the head on the shaft of the predetermined breaking screw 70 allows.

The following briefly explains how the vehicle restraint system according to the invention is mounted. First, the posts 14, 16 and other posts are rammed to size in the underground U. The reinforcing profiles 66 serve for anchoring in the subsoil U and extend beyond the wooden bodies of the posts 14 and 16 into the underground U. As a result, the reinforcing straps 50 ₁ , 50 ₂ and 50 ₃ as well as further reinforcing straps on the posts 14, 16 and attached to other posts or fastened together, as shown in Fig.8 and 9. This means that the Armierungsgurte 50 ₁ and 50 ₂ or 50 ₃ and other Armierungsgurte be screwed together successively by using corresponding profile elements 62. Further, the profile elements 62, as shown in Figure 11 to 13 via predetermined breaking screws 70 to the posts 14, 16 and attached to other posts. During assembly, it is particularly advantageous that the predetermined breaking screw 70 with the mounting plate 72 can be displaced in the longitudinal direction within the C-profile 62 and so any dimensional inaccuracies between fastening straps 50 ₁ to 50 ₃ and the position of rammed to measure posts 14 and 16th and other posts can be compensated. Furthermore, height fluctuations can be compensated to a certain extent, in which the fastening screws 70 are displaced within the slot 74 in each case. This allows the individual Armierungsgurte be screwed with relatively little installation effort with the post.

As a result, the wooden elements can be pushed onto the Armierungsgurte by the receiving slot of a wooden element is pushed onto the respective Armierungsgurt. The Armierungsgurte then come into contact with the base 36 of the respective receiving slot 32 so that the wood elements rest on the Armierungsgurten. Then the connecting screws are inserted into the wooden elements, so that they pass through the slots 54 and 56. The slots 54 and 56 provide appropriate tolerance to compensate for possible deformations of the wood elements can. Depending on your wishes, posts can be attached to any joints. Thus, it is possible, as shown in Figures 1 and 3, to install posts at every other joint. Similarly, it is possible to attach only at every third or fourth joint or at each joint post, so as to adjust the stability of the vehicle restraint system to the respective requirements.

The vehicle restraint system according to the invention is thus relatively easy to install and has no susceptibility to dimensional inaccuracies, the caused by natural deformation of the wood elements. Due to the variability in the assembly, such deformations can be easily compensated with the vehicle restraint system 10 according to the invention.

Figures 14 and 15 show a joint which is slightly modified from the joint of Figure 10. It can be seen that in the joint according to FIGS. 14 and 15, two wood elements 22a and 24a or 22b and 24b are each angled away from one another. Such arrangements are required, for example, when the vehicle restraint system is used to secure curved roads. The arrangement according to FIG. 14 shows an installation with a convex course of the vehicle restraint system, whereas the arrangement according to FIG. 15 shows a concave course of the vehicle restraint system. It can be seen in Figure 14 that the post 16a is no longer located approximately in the region of the center of the profile element 62a, but rather was offset to the left. In the middle region of the profile element 62a, a cut-in region 84a is provided, i. a part of the C-profile is miter cut, leaving the base of the C-profile unchanged. As a result, the C-profile can be deformed in the manner shown in FIG. 14 about the bending axis B which is orthogonal to the plane of the drawing, so that the two wooden elements 22a and 24a can be curved in a convex shape relative to one another. FIG. 14 further shows that the incision region 84 is deformed so strongly that the two cut edges almost come into mutual contact with each other. It is possible to weld the two cut edges together, as indicated at 86a. However, this is only an optional feature to further increase the stability of the vehicle restraint system 10a.

FIG. 15 now shows a concave profile of the vehicle restraint system 10b. Again, the profile element 62b is provided with a notch portion 84b, which allows a corresponding deformation. Further, at the joint 28b, the end portions of the wood members 22b and 24b are chamfered to allow a corresponding deformation.

Figures 16 to 19 show a second embodiment of the invention. To describe this embodiment, the same reference numerals are used for the same effect or the same components, as for the description of the first embodiment according to Figures 1 to 15, but with the lowercase letter "a" readjusted. To avoid repetition, the differences to the first exemplary embodiment should be considered alone.

Essentially two notable differences from the first embodiment according to FIGS. 1 to 15 can be seen in FIGS. 16 to 19. The first difference is that the connecting screws 58a and 60a for connecting the wooden element and reinforcing straps 50a ₂ , 50a _{3 are} not separated Longitudinal holes of the respective Armierungsgurts 50a ₂ , and 50a ₃ run and are not arranged outside of the recess portion 40 a. Rather, the connecting screws 58a and 60a are also used to connect Armierungsgurt 50a ₂ or 50a ₃ and profile element 62a. For this purpose, in each case a spacer element 90a is inserted between the wooden element 20a or 22a and the reinforcing belt 50a ₂ or 50a ₃ . The same also applies to the post-free connection of the two wood elements 22a and 24a according to FIG. 19.

Finally, FIG. 17 shows that the reinforcement profile 66a in the post 16a does not necessarily have to extend to its upper end, but instead can terminate at a distance from the upper end. As a result, the upper portion of the post element remains nick-free and intact, giving the post element a familiar visual appearance.

The second embodiment according to FIGS. 16 to 19 is further simplified with respect to the first embodiment according to FIGS. 1 to 15 with regard to assembly, since fewer screwing operations are required. One of the connecting screws 64a, preferably replaced in each case the middle of a three connecting screws 64a, which serves to connect wood element 20a or 22a and the respective Armierungsgurt 50a ₂ and 50a ₃ . The same naturally applies to the post-free connection point according to FIG. 19.
