Abstract

The device has posts (1, 2) connected with a ground on which the protection device is arranged, where the ground is a part of a bridge construction such as rim beam. A stabilizing element e.g. box section (4), extends in a longitudinal extension direction of the protection device and is connected with the post (1). A guide element (3) is connected with the post (2) by a spacer element (5). The stabilizing element is not connected with the post (2) and the guide element is not connected with the post (1).

Description

The invention relates to a protective device on traffic routes according to claim 1.

From the DE 20 2006 013 759 U1 is a protective device on traffic routes known in which guide-carrying posts are rammed into a ground. This ensures good stability of the entire safety guard. However, it is not easy to scratch posts on any surface. Thus, in particular in the area of bridges such a ramming of posts for solid anchoring in the ground is not possible or desirable.

The present invention has for its object to provide a protective device on roads, which can be placed on a variety of differently procured surfaces, especially on a bridge, and yet has a good retention.

This object is achieved with a protective device on traffic routes with the features of claim 1. Accordingly, such a protection device not only has a single post, to which different guiding or stabilizing elements are attached, but rather at least one first post, to which at least one stabilizing element is attached, and at least one second post, on which at least one guide element is attached. The guide element is connected by means of at least one spacer element with the second post. Both the first post and the second post are each connected to a substrate on which the protection device is arranged. The stabilizing element is not connected to the second post (s), and the guiding element is not connected to the first post (s).

In one embodiment of the invention, the substrate is a bridge construction or a part of a bridge construction, namely in particular a bridge cap. The bridge cap is understood to mean the area between a curb running alongside the actual traffic route and an outer edge of the bridge. The bridge cap usually serves to receive a protective barrier and a railing.

With a protective device according to the invention the effect is achieved that the posts are anchored to the ground so that on the one hand no concrete or asphalt parts are torn out of the ground around the anchorage, whereby damage to the substrate is avoided. On the other hand, however, the overall system of the guard still provides enough elasticity to ensure a sufficiently high absorption of impact energy by a suitable deflection of the straps (that is, the stabilizing element and the guide element).

In one embodiment of the invention, the stabilizing element, the guide element and the spacer element and the connection of these elements are configured with each other in the same way as in a protective device which is anchored by means of rammed posts in a ground. That is, as many of the same structural elements as in a rammed guard can be used, so that the structure of a protective device, which consists of rammed sections and otherwise anchored underground sections, is made possible in a simple manner.

In particular, when the guard is to be placed on a bridge cap, arise due to the specific local configurations of bridge structures special requirements for the protective device. Thus, the space available for deformation of the protective device is much more limited than in an arrangement on another surface. This means that the smallest possible range of action (W ≤ 4) should be achieved for a containment stage H2 according to EN1317. Furthermore, when mounted on a bridge cap too take into account that bridge caps usually have a standardized design, which requires an additional restriction of the possible variations. Furthermore, due to normative specifications, a railing is regularly mounted on a bridge cap. This guardrail should not be touched during a deformation of the safety guard, as the protective effect of the safety guard must be achieved without the aid of the guardrail. Consequently, the space available for dynamic deformation, in particular the straps of the guard, is extremely limited. At the same time, however, this space must be fully exploited to form a non-deformable protector overall system. If the safety system as a whole would be rigid, this would mean that large parts of the bridge construction would be torn out of the bridge cap in the event of a motor vehicle colliding with the safety guard. As a result, the stability of the entire bridge construction would no longer be guaranteed. At the same time, however, no reinforcement of the bridge cap for mounting the protection device can take place, since the protective device is intended to be mounted on existing bridges. However, these must not be subsequently reinforced.

The protective device according to the invention meets the requirements for installation on a bridge cap. Thus, too much deformation is not allowed in the upper part of the guard, nor is the entire impact load is concentrated in a collision of a vehicle on the guard on individual posts or individual anchor.

In a variant of the invention, the stabilizing element is designed as a guide element, so that the protective device has two guide elements fastened to different posts.

In a further alternative of the invention, the stabilizing element is designed as a box profile. That is, the guard then has a box profile attached to a post and a baffle attached to another post.

In a variant, the protective device is characterized in that at least one connecting element is provided for connecting the stabilizing element or box profile with the first post, which is connected on the one hand to the first post and on the other hand is arranged in a form-fitting manner in the box section. In this case, the stabilizing element designed as a box profile preferably has an opening which is formed on the underside of the stabilizing element and extends in its longitudinal direction.

Through this opening, the connecting element during assembly in the box section can be introduced and removed during disassembly of this.

This mounting variant comes without fasteners such as screws between the connecting element and the stabilizing element, so that larger tolerances with respect to the distance of each first post to each other are possible. It plays for this attachment of the stabilizing element to the first post each by means of a connecting element due to the omission of fasteners no essential role, whether the distance between the individual first post is always the same. Thus, the installation of the protection device over other protection devices is simplified.

Preferably, the opening in the box section extends over the entire length of the stabilizing element. This facilitates the production of the stabilizing element and reduces the required material cost.

The connecting element preferably has a substantially plate-shaped main surface, which may be provided with recesses and which is oriented in the mounted state substantially perpendicular to the longitudinal extension direction of the stabilizing element.

So that the connecting element can be introduced through the opening in the stabilizing element, its main surface is preferably arranged at the beginning of assembly of the stabilizing element on the connecting element substantially parallel to the longitudinal direction of the hollow profile. During assembly, the connecting element is rotated in the hollow profile, so that its main surface has an angle between about 0 ° and about 90 ° to the longitudinal direction of the hollow profile. As a result, the connecting element is moved into the position which it preferably occupies in the mounted state.

The connecting element is thus designed such that its main surface during assembly on the stabilizing element from an initial position in which the main surface is substantially parallel to the longitudinal direction of the hollow profile and can be introduced into the opening of the hollow profile, in an end position in which the main surface substantially runs perpendicular to the longitudinal direction of the hollow profile, is pivotable.

To increase the stability of the connecting element, this preferably has at least one lateral edge region, which is arranged at an angle to the main surface. It is advantageous if between the at least one edge region and the main surface an angle of 85 ° to 95 ° is formed, wherein in particular a right-angled arrangement is preferred. The at least one edge region advantageously has a width that is smaller than the width of the main surface. The width of the edge region is understood to mean its shorter extent in a plane which forms the edge region at an angle to the main surface. The width of the main surface is the extent of the main surface, which extends in the assembled state substantially perpendicular to the longitudinal direction of the stabilization element or hollow profile.

Preferably, the connecting element has two angled edge regions, so that results in a cross-sectionally Z-shaped shape of the connecting element. In this way, a high stability of the connecting element is achieved. The edge regions can be of different widths and also protrude at a different angle from the main surface of the connecting element.

The positive connection between the connecting element and the hollow profile is preferably achieved in that the hollow profile surrounds the connecting element, in particular with at least one lower portion, so that it undercuts the connecting element. The lower section is preferably the region of the hollow profile arranged adjacent to the opening. An undercut connection between the two elements is ensured, in particular, when so many legs or surfaces of the hollow profile engage around the connecting element that the two elements can no longer be detached from each other without twisting or twisting.

In addition to the positive connection, a frictional connection between the hollow profile and the connecting element is preferably additionally provided in that the connecting element with its at least one lateral edge region at least partially presses against at least one inner side surface of the hollow profile and thereby builds a clamping between the hollow profile and the connecting element.

The connection between the hollow profile and the connecting element is preferably designed such that it can be released again by a force which acts on the protective device as a result of an impact of a vehicle. This means that the stabilizing element at a sufficiently high force on the protective device from the Unscrewing the connection element and can absorb energy from the impact of the vehicle already here and by a subsequent deformation.

In order to achieve an attachment of the connecting element to the post, the connecting element preferably has an elongated opening, in particular a slot, which is arranged in a lower portion of the connecting element. This lower portion of the connecting element is not arranged inside the stabilizing element. In order to achieve a secure fixation of the connecting element to the post, it is preferably fixed by at least one fastening means to the post. In particular, a screw or a rivet is considered as such a fastening means.

The spacer element preferably has a fastening region with openings, in which it is connected by at least one fastening element with the post, wherein the fastening element engages thereto through one of the arranged in the fastening region of the spacer element openings. Furthermore, the number of openings in the attachment region of the spacer element is preferably greater than the number of attachment elements which reach through the openings.

In a preferred embodiment of the invention, the total height of the protective device, measured from the top of the floor on which the protective device is arranged, to the top of the stabilizing element or to the top of the first post or to the top of the second post (in particular, depending on which of these upper edges is farthest from the ground), greater than 80 cm, in particular greater than 85 cm, and less than or equal to 90 cm.

By dispensing with a number of fasteners in the simultaneous presence of breakthroughs and an associated saving of material in the spacer element and in the post material costs of the protection device is significantly reduced. Also can be achieved by a particularly compact design, which expresses itself in a low overall height of the protective device, a significant reduction in material. Thus, advantageously, standard elements from which known protective devices are constructed, by a corresponding new, a lower overall height of the protective device enabling combination - possibly waiving a number of fasteners - are used for mounting a protective device according to the invention. From the arrangement of the individual Elements of the protective device results in spite of the inventively achieved material reduction stability that meets the high, desired requirements.

In order to enhance a stabilizing effect of the stabilizing element for the protective device, the stabilizing element is preferably arranged on an upper region of the first post such that it covers the upper edge of the post and thus represents the upper end of the protective device.

Preferably, the stabilizing element and / or the guide element consist of at least two segments, each of these segments having at its first end a first connecting portion and at its second end a second connecting portion. The ends of the segments are to be understood as the end regions of the segments, which are arranged in the longitudinal extension direction of the segments farthest from the respective center of the segments. The first connection portion of a first segment can be associated with the second connection portion of a second segment in such a way that a connection area is formed, via which both segments are interconnected.

In order to enable a quick and easy connection of two segments, each segment preferably has a smaller cross-section at its first connection portion than at its second connection portion. On the one hand, this cross-section may relate to the entire segment, but on the other hand, it may include only the profile widths of the segment. With this different cross-sectional shape in the two connecting portions of each segment, it is possible to insert two segments into each other. For this purpose, the first connection portion of a first segment is introduced into the second connection portion of a second segment. Depending on the size and type of cross-sectional difference between the connecting portions, in particular depending on the transition of the connecting portion with the smaller cross-section to the average cross section of the segment, different sized sections of each segment are part of the connecting portion.

In order to achieve a connection between two segments not only by a nesting or a juxtaposition of the connecting portions, the connecting portions preferably have openings, which are aligned with each other in the formation of a common connection region of two connecting portions and can be provided with fastening means.

Preferably, the invention is configured such that at least one fastening element for fixing two segments engages through one of the openings mentioned. If a screw is used as the fastening element, two segments can be screwed together in this way. The number of openings in the connecting region of two segments is greater than the number of fasteners that reach through the openings. In this way, which is comparable to the material savings achieved by reducing the fasteners for attachment of the spacer to the post, additional material reduction of the guard is achieved. In reducing the number of fasteners, however, care must be taken that the stability of the protective device, which is also influenced by the connection between the segments of the stabilizing element and / or the guide element, is not undesirably lowered.

In order to facilitate the mounting of the spacer element on the second post, the spacer element preferably has at least one connecting means which serves to connect the spacer element to the second post. For this purpose, the connecting element engages in a receiving means on the second post. The spacer element can then, while it is already held by the connection between the connecting means and the receiving means, be fixed by at least one fastening element on the second post. The connecting means may be formed, for example in the form of a hook on the spacer element, said hook can then be inserted into a corresponding tab as receiving means. This results in a plug connection between the spacer element and the second post.

The spacer element is preferably arranged on the second post such that it extends substantially only in one direction from the second post. In an alternative embodiment of the invention, the spacer element is arranged on the second post such that it extends in substantially equal parts to both sides of the second post. The two sides of the post thereby comprise a front and a back of the post, with the front side facing the back. If one looks in the lateral cross-section of a protective device with such arranged spacer element and posts, the result is a cross-shaped arrangement between the spacer element and posts.

So that the protection device can protect not only one traffic route, but two traffic routes or two directional traffic lanes of a traffic route at the same time, the spacer element preferably has two guide elements, one of which on the front side and the other is arranged on the back of the post. This may be useful, in particular, if there is another traffic route to be protected (for example, a cycle path) on the side of the protection device facing away from the traffic route to be protected. This design can also - especially for narrow median strip - a compact protection device for two adjacent traffic routes or directional lanes of a traffic route are provided. This construction is particularly suitable if there is no difference in level between the two traffic routes.

A comparable embodiment of the protective device can alternatively also be achieved by not using a common spacer element but two separate spacer elements. Each of these two spacer elements would be provided in this embodiment with a guide element, wherein the one guide element to the front and the other guide element would be directed to the back of the post.

In order to provide two traffic routes or two directional lanes of a traffic route, which are connected to each other over a narrow central strip and also have a difference in level, to be provided with a protective device according to the invention, the first and the second spacer element are not in a preferred embodiment of the invention the same, but at different heights attached to the post. As a result, the guide elements arranged on the spacer elements are at different heights relative to the ground at the position of the post. This makes it possible to set in the desired height of the guide elements with respect to the level of the surface of the respective traffic route as desired.

In order for the protective device according to the invention, despite its compact design and material reduction, to have a high stability, the elements of the protective device, in particular the posts and the spacer elements, are arranged relative to each other such that the protective device has a holding capacity which at least the containment level H2, determined according to EN 1317-2. In principle, however, the protective device can also be designed so that it can reach a different degree of containment.

In an alternative embodiment, the first post and / or the second post with the respective end in the longitudinal direction of the post, which points in the mounted state to the ground, connected to a base plate. It is possible that each post is arranged on a separate base plate. The connection of the first post and / or the second post with the base plate can in particular be done by welding, with rivets, fittings and similar compounds are conceivable.

In order to allow a simple connection between the protection device and the ground, the base plate is provided and adapted to be connected to the ground. For this purpose, the base plate on several openings, which are suitable for receiving bolts, screws or anchors. These fasteners may optionally be inserted using suitable washers in the respective openings.

In order to compensate for unevenness in the substrate or to prevent liquids or other substances from penetrating under the base plate between the surface of the substrate and the underside of the base plate, in an alternative embodiment a sealing element is arranged between the base plate and the substrate in the assembled state of the protective device.

In order to achieve a particularly simple and inconspicuous arrangement of the sealing element below the base plate, the sealing element is executed in a variant of the invention as a sealing plate, which is essentially a same area (that is - apart from the height - same dimensions) and also a same hole pattern as the base plate has. It is possible that the opening cross section of the holes in the sealing plate from the opening cross section of the holes in the base plate deviates. However, this does not change the fundamentally identical hole pattern, which in particular results in an alignment of the holes in the sealing plate with holes in the base plate.

In order to ensure a particularly simple assembly and good stability of the protective device, the first post and the second post are connected in a variant of the invention with a common base plate. This makes it possible in a particularly advantageous manner to use a base plate with a standard hole pattern, which allows easy connection of this base plate with standard provided in a bridge cap receiving openings for fasteners. As a result, extensive structural measures for setting new anchor or fasteners are not required. In addition, since the forces acting on the fastening means (anchor forces) and the stress of the base plate very much on the distance of the individual fasteners depends on each other, the fasteners may not be too far apart. This is especially true because the anchor or fasteners in terms of maximum absorbable tensile forces regularly have only a limited approval. Consequently, it is advantageous if the distances between the fastening elements are in the normal range, so that standard approved fasteners or anchors can be used.

In an alternative embodiment, the posts are arranged offset to one another on the base plate. It is provided in particular that the second post is arranged closer to a traffic route than the first post. This has the consequence that the guide element is arranged closer to the traffic route than the stabilizing element. Although the guide element is independent of the relative post arrangement closer to the traffic route due to the spacer element used, a further shift to the traffic route is achieved by the post arrangement. If a vehicle collides with the protective device, it first strikes the guide element, so that initially occurring impact forces are introduced via the guide element into the second post. This post can be claimed up to its breaking load. Part of the resulting impact energy is dissipated in the underground. In the further time course of the impact of the vehicle on the protective device, the first post is subjected to a corresponding impact energy by deformation of the stabilizing element, so that a deformation of the first post occurs. That is, the entire impact energy is introduced in two temporally separate stages on the second post and the first post and an optional base plate in the underground. By this division of the load acting on the protective device a more favorable energy input into the ground is achieved. This has the consequence that the fasteners that are used to attach the base plate on the ground, less stressed at one time than is the case with conventional systems. Likewise, the substrate is much cheaper charged with energy or force, so that the detachment of individual parts from the ground is avoided in an impact on the protective device.

By a staggered arrangement of the posts on the base plate also allows a greater degree of freedom in the deformation of the individual post. As a result, as late as possible a matching of the deformed belt (that is, the deformed guide element or the deformed stabilizing element) is achieved at the other post. Thus, the probability that the first loaded second post is acted up to its breaking load, increased, so that the second post breaks before the guide element can bounce on the hitherto undeformed first post.

In order to allow a better introduction of force from the first post and / or the second post into the ground or the base plate, at least one reinforcing element is attached to the first post and / or to the second post. This reinforcing element causes increased stability of the respective post relative to a force acting on the respective post. As a result, a higher breaking load of the post is achieved with a bending load of the loaded post. The breaking load is usually reached at the junction between the post and the base plate first. By the reinforcing element, however, stress on the joint between the post and the base plate can be reduced.

In order to allow a particularly simple connection of the reinforcing element to the base plate, this is welded to the base plate; However, other connection methods can also be used in principle. In particular, it is provided to perform a weld between the reinforcing element and the base plate in a discontinuous manner, so that gaps or cavities between the reinforcing element and the base plate occur. Because of these cavities, it is basically possible to attach an inner weld. Furthermore, it is possible for water or other liquids, which accumulate in the region of the reinforcing elements, to be brought from one side of the reinforcing element to the other side of the reinforcing element. This is of particular interest when the base plate is not placed absolutely flat, but slightly inclined so that a flow of liquid along the base plate is forced. In this way, it is possible, for example, water, which runs down from an upper portion of the protection device to individual elements of the protection device, specifically to lead away from the protection device.

In a variant of the invention, the reinforcing element has a cross-sectionally C-shaped configuration. Here, the open side of the C (a material-free area of the C-shaped profile) facing away from the traffic route, so pointing to the traffic route towards no sharp edges of the reinforcing element. A wheel of the vehicle touching the protective device is gently rejected, without getting caught in the reinforcing elements.

In order to allow particularly favorable deformation properties, the first post and / or the second post are formed in a variant in a cross-sectionally C-shaped configuration. As a result, a twisting of the posts when bending is achieved be so that at a maximum stress nor a deformability of the respective post above its stiffening is achieved. Between the two ends of the C, a material-free region is present in such an embodiment.

In a variant of the invention, the first post and the second post are arranged relative to each other such that the material-free region of the first post faces the second post. In particular, the material-free region of the second post also faces the first post. That is, a portion lying between the first and second posts is flanked on both sides by the material-free region of the first post and the material-free region of the second post.

In one embodiment of the invention, the distance between two adjacent first posts and the distance between two adjacent second posts are the same. The adjacent first posts are the first posts following each other in the protective device. Likewise, as adjacent second posts to be considered in the protective device immediately consecutive second post. That is, if in a guard a first post, then a second post and then again a first post (and no further post) are arranged one behind the other, the two first posts are adjacent first posts, while no adjacent second posts exist for the second post ,

In a further embodiment of the invention, the distance between the first post and an adjacent second post (that is the second post closest to the first post) is small compared to the distance between the first post and an adjacent further first post , That is, in this embodiment, there is a succession of each two closely spaced posts, namely a first post and a second post, and then a greater distance to a further pair of first and second posts before. As a result, a similar structure (but taking advantage of favorable effects of the invention) as in a protective device can be achieved, which provides only a single post for different control or stabilizing elements.

In a particular embodiment of the invention, the first post and the second post have different lengths from each other. That is, in the assembled state of the guard, the first post and the second post at different heights above the ground. The longer post rises higher above the ground than the shorter post.

In a further embodiment of the invention, the first post is longer than the second post. That is, when a vehicle impacts on the guard and first bounces against the baffle, initially only the shorter second pillar is impacted with a corresponding impact energy.

The Figure 1A shows a side view of a section of a protective device with a plurality of first post 1 and a plurality of second posts 2, of which for clarity, only a few are provided with the corresponding reference numerals. In each case, a first post 1 and a second post 2 are arranged together on a common base plate 11 as a base plate by welding. This results in a plurality of pairs of posts, which are each mounted on a base plate 11. Furthermore, this results in an alternating sequence of first post 1 and second post 2. Each foot plate 11 is firmly anchored by means not shown anchors as fastening means in a substrate U.

Above the surface of the substrate U are at each first post 1 a box section 4 as a stabilizing element and arranged at each second post 2 a guardrail 3 as a guide element. The box section 4 is not connected to the second post 2. Also, the guardrail 3 is not connected to the first post 1. The first post 1 and the second post 2 thus carry different elements of the protective device. The box section 4 is seated on the first post 1 so that it covers the upper edges of the first post 1. At the same time, the first posts 1 are longer than the second posts 2. The Box section 4 thus forms the upper end of the entire protective device. The guardrail 3 and the box section 4 are made of hot-dip galvanized sheet steel. The height between the surface of the substrate 2 and the upper edge of the box section 4 is in the in the Figure 1A illustrated protection device preferably 90 cm.

The distance between the individual first posts 1 of the protection device is preferably 1.33 m. The distance between the individual second posts 2 is also preferably 1.33 m. The distance between a first post 1 and an adjacent second post 2, so the second post 2, which is mounted together with the first post 1 on the same base plate 11 is preferably about 3 to about 10 cm, in particular about 4 cm. With this post distance a good stability of the protective device is achieved at the same time relatively low cost of materials. The protective device of Figure 1A has an extension of several tens of meters, wherein the distance between the individual first post 1 and the individual second post 2 preferably always remains the same.

In the FIG. 1B is the one in the Figure 1A shown from the side protection device in a view from above. In addition to those in the Figure 1A shown elements such as the base plate 11, the guardrail 3 and the box section 4 are spacers 5 can be seen in this illustration as spacers. These spacers 5 are arranged on each second post 2 and carry the guardrail 3. Depending on the length of the spacers 5, the guardrail can thus be positioned closer to a road as a traffic route or further away from the road. By means of the spacers 5, the relative position of the guardrail 3 to the second post 2 can be varied.

The spacers 5 serve not only the fixing and positioning of the guardrail 3, but in addition to receiving energy when a vehicle comes off the road and bounces against the guard. In principle, it is also conceivable to design the second post 2 in such a way that it assumes the functions of the spacer 5 so that it does not have to be formed as a separate part. Due to the configuration of the spacers 5 and by their arrangement on the second post 2 and in particular by their fixation to the second post 2, the stability of the entire protective device and its area of action, that is the dynamic displacement of the system, can be influenced. The aim is a relatively low effective range W (in particular W ≤ 4), which with a protective device as in Figures 1A and 1B represented achieved. This protection device meets the requirements of containment level H2 according to EN 1317-2. Opposite higher ones Constructions, which reach the same containment level H2, are in the in the Figures 1A and 1B shown protection device, a material savings of 35% possible. This has several benefits. In addition to a lower cost of materials and the associated cost reduction and conservation of resources as a faster and easier construction of the protection device according to the invention is possible, resulting in a further cost reduction.

The Figure 1C shows a cross section through the protective device of FIG. 1B along the line CC. At the second post 2, the spacer 5 is connected to the second post 2 at its upper end. For the preparation of this compound, the spacer 5 has first been hooked by means of a connecting element, not shown, in a likewise not shown receiving element on the second post 2. Subsequently, this connection between the spacer 5 and the second post 2 was fixed by screws, which are inserted into first openings 7 of the spacer 5. On the spacer 5, two more openings 8 are arranged beyond, but not serve to receive screws. They convey rather a material reduction. At the maximum distance from the second post 2 end of the spacer 5, the guardrail 3 is arranged. It is connected by means of a screw 6 with the spacer 5. In this case, the guardrail 3 is arranged so that it is located on a front side V of the second post 2.

Behind the second post 2, the first post 1 is arranged. At the upper end of the first post 1 (and thus due to the shorter length of the second post 2 compared to the first post 1 above the spacer 5), a bracket 10 is connected as a connecting element fixed to the first post 1. For this purpose, the bracket 10 has a slot 7, which is penetrated by a screw and the bracket 10 thus fixed to the first post 1. The upper portion of the bracket 10 is disposed in the interior of the box section 4 and is encompassed by this. The bracket 10 is attached to the first post 1 in such a way that the box profile 4 connected to the bracket 10 is flush with the upper edge of the first post 1.

The first post 1 and the second post 2 are both welded to the base plate 11. In this case, an inclined stiffening plate 12 is additionally attached as a reinforcing element between the second post 2 and the base plate 11. The stiffening plate 12 is welded to both the second post 2 and the base plate 11. It increases the stability of the connection between the second post 2 and the foot plate 1. Between the first post 1 and the foot plate 11 is also in Similarly, a stiffening plate 13 is attached, which in the illustration of FIG. 1D you can see.

The foot plate 11 is anchored by anchors 110 as fastening elements in the underground U. The foot plate 11 is not aligned absolutely straight, but has as well as the substrate U an inclination of about 4%. That is, the base plate 11 is not additionally inclined relative to the substrate U, but performs its inclination.

The FIG. 1D shows a perspective view of a corresponding to the FIGS. 1A to 1C trained embodiment of a protective device, wherein the sequence of the first post 1 and second post 2 in reverse than in the FIGS. 1A to 1C is selected.

The box section 4 is not formed in one piece, but consists of several segments. The connection between the individual segments of the box section 4 is in the FIG. 2 shown. That's how it shows FIG. 2A the connection area between a first segment 40 and a second segment 42 of the already from FIG. 1 known box profile 4. The first segment 40 has a connecting portion 41 which is located at one end of the first segment 40. This connection portion 41 may be inserted into a second connection portion of the second segment 42 as shown in FIG FIG. 2A shown. This second connecting portion of the second segment 42 is the one end of the second segment 42. The first end of the second segment 42, not shown, is shaped analogously to the first end of the first segment 40, that is to say like the first connecting portion 41. Thus, as many segments as possible can be connected to the second connection section of the respectively adjacent segment by connecting their first connection section 41.

In the region of the ends of the first segment 40 and the second segment 42, that is, in their respective connecting portions, the segments have openings, which are partially designed to pass through screws 6, which fix the individual segments together. The openings, which are designed to pass through screws, should be referred to as first openings 7. The breakthroughs that are not intended to be penetrated by screws should be referred to as second openings 8. The first openings 7 are shown with a larger diameter than the second openings 8. In fact, however, they can be the same diameter.

When the first segment 40 is inserted with its connecting portion 41 in the second segment 42, it is positioned so that the openings 7 and 8 of the individual segments 40 and 42 are aligned with each other. In this way, 7 screws can then be introduced into the openings, which connect the first segment 40 with the second segment 42.

From the synopsis of FIGS. 2A, 2B and 2C , which show a first side view, a top view and a second side view of the connection area between the first segment 40 and the second segment 42, gives an overview of the number of screws used for connection 6 and their arrangement in the connection area between the first segment 40 and the second segment 42. The view is the FIG. 2B opposite to the view of FIG. 2A turned 90 ° and the view of Figure 2C opposite to the view of FIG. 2B rotated by another 90 ° in the same direction. That is, those in the FIG. 2A upwardly facing surfaces of the first segment 40 and the second segment 42 are in the FIG. 2B arranged on the right side and point in the Figure 2C downward.

As from the cross section through the box section 4 in the FIG. 2D it can be seen, seven screws 6 are sufficient to connect the first segment 40 with the second segment 42. The fact that only the first openings 7, but not the second openings 8 are provided with screws 6, a material savings is achieved by means of screws 6 saved. Surprisingly, this material saving does not lead to a substantial destabilization of the connection between the first segment 40 and the second segment 42, so that the advantageous properties of the protective device are retained.

Also, the guardrail 3 in the Figures 1A and 1B shown protection device is not formed in one piece, but consists of several segments. In the FIG. 3 the connection region 32 between a first segment 30 and a second segment 31 of the guardrail 3 is shown. The connection region 32 is defined by the overlapping sections of the first segment 30 and the second segment 31. He is the one indicated by the solid line L in the left area of the FIG. 3 , which represents the left end of the first segment 30, as well as the dashed line L 'in the right area of FIG. 3 , which represents the right end of the second segment 31, limited.

Analogous to that in the FIG. 2 illustrated connecting portion of two segments 40 and 42 of the box section 4 also have the segments 30 and 31 of the guardrail 3 a number of first openings 7, which are provided so that screws reach through them and thus connect the first segment 30 with the second segment 31. Furthermore, two second openings 8 are arranged in the connection region 32, which serve the material reduction, but are not penetrated by screws.

The box section segments 40, 42 and the guard rail segments 30, 31, as well as the other elements of the protection device, due to their standardized design, can also be used for other protective devices in which more screws are to be used. Conversely, standard elements of other protective devices can also be used for the protective device according to the invention.

In the center of the connecting region 32, a third opening 9 is additionally arranged, through which a screw or other fastening means for fastening the guard rail 3 to the spacer 5 can be guided.

A common feature of the connection area between the first segment 30 or 40 and the second segment 31 or 42 of the guardrail 3 or the box section 4 is that the screw pattern does not form with the hole pattern formed by the first openings 7 and the second openings 8 is consistent. Rather, more breakthroughs 7 and 8 are available as screws 6 are used in these breakthroughs.

To illustrate the connection between the box section 4 and the bracket 10 shows the FIG. 4A an enlarged view of these two elements. The distance between opposite surfaces of box section 4 and bracket 10 is shown larger than it actually is.

The bracket 10 has a substantially planar main surface 100, to which adjoin two opposite lateral edge regions 101, 102, which project at an angle from the main surface 100 of the bracket 10. In this case, the first edge region 101 is angled so that it protrudes into the plane of the paper, while the second edge region 102 is angled so that it protrudes from the plane of the paper. The angled edge regions 101, 102 thus extend substantially in the longitudinal direction of the box profile. The arrangement of the edge regions 101, 102 of the bracket 10 is in the FIG. 4B shown separately.

Further, the bracket 10 has a lower, substantially rectangular, in particular square bracket portion 103, which serves to attach the bracket 10 to the post 1 and for this purpose forms a slot 7. Next is a recess 104 in the bracket 10th provided, which serves to save material and increases the elasticity of the bracket 10. The recess 104 preferably corresponds in size to the bracket section 103 and is preferably likewise of a square design. It is formed centrally on the upper edge region of the bracket 10.

To connect the box section 4 with the bracket 10, the bracket 10 is first inserted through a arranged on the underside of the box section 4 between the lower portions 45 opening 46 (in which the post 1 is inserted, see, for Fig. 1C) , which preferably extends over the entire length of the box section 4, introduced into the box section 4, wherein the bracket is oriented with its main surface 100 parallel to the longitudinal direction of the box section 4. After the bracket, with the exception of the lower bracket portion 103 is disposed inside the box section, it is rotated by approximately 90 °, so that the main surface 100 of the bracket 10 is now oriented substantially perpendicular to the longitudinal direction of the box section 4.

On the one hand, this results in a positive connection between the bracket 10 and the box section 4, since the lower sections 45 of the box section undercut the bracket 10 in this orientation. On the other hand, a frictional connection between the edge regions 101, 102 of the bracket 10 (or at least portions of these edge portions 101, 102) and the side walls of the box section 4 is achieved because the edge portions 101, 102 jammed with the side walls of the box profile.

The bracket 10 is now by means of a screw or other fastener in the region of the slot 7 at the in the FIG. 4A not shown post 1 fixed.

By the angled edge regions 101, 102 increases the area in which the bracket 10 and the portions 45 of the hollow section 4 form a positive connection.

Due to the angled arrangement of the edge regions 101, 102 on the bracket 10, a larger surface is furthermore provided, via which the bracket 10 enters into a frictional connection with the box profile 4. As a result, the frictional connection between the bracket 10 and the box section 4 is made more stable than would be possible without angular arrangement of the edge regions 101, 102.

As mentioned, the lower portions 45 of the box section 4 grip around the bracket 10 in such a way that an undercut of the bracket 10 results through the box section 4. Like from the FIG. 4A it can be seen, the box section 4 can not readily from the bracket 10th be lifted off. Upon the action of large forces on the protective device and an associated distortion of the protective device, the undercut connection between the box section 4 and the bracket 10 can be solved. In this way, restoring forces that could be exerted by a firmly connected to the post 1 box section 4, avoided. Rather, a deformability of the box section 4 is made possible by the Ausknöpf the box section 4 from the bracket 10, by means of which additional energy can be absorbed.

The FIG. 4B shows the bracket 10 in a plan view, that is, a top view. In this representation, the cross-sectionally Z-shaped shape of the bracket 10, which results from the angular arrangement of the edge regions 101, 102, can be well recognized. Apart from the angularly protruding edge regions 101, 102, the bracket 10 has a substantially planar shape. The angled edge regions 101, 102 have a width of about 2 to about 3 cm; their length and their thickness correspond largely to the corresponding dimensions of the substantially flat main surface 100 of the bracket 10.

The first edge region 101 is in the FIG. 4B angled upwards. This corresponds to a bend in the plane of the paper (ie to the rear) in the FIG. 4A , The second edge region 102 is angled by 180 ° with respect to the first edge region 101, which in the FIG. 4B is shown by an angled down and a bend out of the paper plane (forward) in the FIG. 4A equivalent.

In the FIG. 5 is a cross section through a second embodiment of a protective device shown. This embodiment differs only slightly from that in the Figure 1C illustrated example, so that reference is made to the explanations there. Unlike the one in the Figure 1C illustrated cross section through a protective device is the spacer 5 in the illustration of FIG. 5 not just one-sided, but two-sided. That is, it extends from the second post 2 not only to the front V, but also to the back R of the post. In this way, two guide elements 3 can be attached to the spacer 5, so that the protection device protects two roads S or road sections.

A comparable protective effect can also be achieved in that two spacers 5, which as shown in the Figure 1C are configured, are arranged on the second post 2. One of these spacers would be on the in the FIG. 5 visible side surface of the post 1, while an equivalent ausgestalteter spacer 5 at the in the FIG. 6 invisible side surface of the Post 1 would be appropriate. In this arrangement, it should be noted that the first spacer extends to the front V of the second post 2, while the second spacer 5 extends to the back R of the second post 2.

Regardless of whether working with a spacer 5 extending to the front V and to the rear R of the post 1 or with two spacers 5 arranged on different side surfaces of the second post 2, it is possible to provide a protective device comprising two streets with a single-row post arrangement S or road sections can protect.

The FIG. 6 shows a cross section through a third embodiment of a protective device. The protector of this embodiment is adapted to be used on adjacent roads S or road sections having a level difference from each other. This is the case, for example, when the surface of the substrate 2 is higher at a first road S than at a second road S '.

The general connection of the spacer 5 on the second post 2 and the crash barriers 3 on the spacers 5 and the bracket 10 on the post 1 and the box section 4 on the bracket 10 differs in the FIG. 6 example not shown in the Figure 1C and the FIG. 5 shown variants, so that reference is made to the descriptions there.

The spacers 5 can - as in the FIG. 6 shown - be arranged on a common side surface of the second post 2. Alternatively, however, they can also be arranged on respectively different side surfaces of the second post 2. The height at which the spacers 5 are mounted on the second post 2 results from the desired height which the guardrails 3 should occupy above the respective street level.

The FIG. 7A shows a side detail view of a pair of posts of the protective device of FIG. 1 consisting of the first post 1 and the second post 2. The viewing direction of the posts 1, 2 is identical to that in the Figure 1C chosen line of sight.

Both the first post 1 and the second post 2 are welded to the base plate 11. Here is the second post 2 in addition to the already from the Figure 1c known stiffening plate 12 additionally connected to the base plate 11, including the Reinforcing plate 12 is welded to both the second post 2 and with the base plate 11. In addition, the first post 1 is also stabilized with a stiffening plate 13 against a break from the base plate 11. The further stiffening plate 13 is similar to the stiffening plate 12 welded to both the first post 1 and the base plate 11. It is used to force application of acting on the first post 1 forces in the base plate 11, so that not only the welding of the foot part of the first post 1 is used to introduce force.

The FIG. 7b shows the pair of posts the Figure 7a in a direction rotated by 90 °, as indicated by the arrow B in the Figure 7a is indicated. In this illustration, the stiffening plates 12, 13 are arranged in front of the first post 1 and the post 2. Otherwise, for further explanation of the FIG. 7b to the explanatory notes to the Figure 7a directed.

The FIG. 7c shows a plan view of the post pair of the FIGS. 7a and 7b , In this plan view, it can be seen that the first post 1 is arranged offset relative to the second post 2 on the base plate 11. As a result, the second post two moves closer to a road S as a traffic route, so that a guardrail, which is attached by means of a spacer to the second post 2, further protrudes toward the road S than a box profile mounted directly above the first post 1.

Both the first post 1 and the second post 2 have a C-shaped profile cross-section. Between the ends 112 of the C of the cross section of the first post 1, a material-free portion 113 is formed. Likewise, a material-free portion 213 is formed between the ends 212 of the C of the profile cross-section of the second post 2. The material-free sections 113, 213 of the two posts 1, 2 are aligned with each other so that they face each other. Thus, the material-free section 213 of the second post 2 points to the first post 1, while the material-free section 113 of the first post 1 points to the second post 2.

Also, the stiffening plate 12 and the further stiffening plate 13 have a C-shaped profile cross-section. However, the opening of this C-shaped profile cross section to the first post 1 and the second post 2 is oriented towards. A vehicle traveling on the road thus does not come into contact with the open area of the profile cross section of the stiffening plate 12 or of the further stiffening plate 13. In a view from the road S (as in FIG FIG. 7b shown), thus also gives a complete overall impression of the post pair from the first post. 1 and the second post 2 and the stiffening plate 12 and the further stiffening plate 13.

So that the foot plate 11 can be fixed on the substrate U, it has four openings 111 which can be penetrated by anchors 110, as in the Figure 1c shown.

The FIG. 7d shows a further plan view of the base plate 11, wherein this view by 90 ° relative to the view of FIG. 7c is turned. At the second post 2, a spacer 5 is attached by means of a screw 6 as a spacer element. The spacer 5 serves to receive an unillustrated guide element.

The FIG. 8 shows a plan view of a sealing plate 14 which is positioned in the mounted state of the protective device between the base plate 11 and the substrate U, on which the protective device is arranged. It serves to compensate for unevenness of the substrate U with respect to the base plate 11. Like from the FIG. 8 it can be seen, the sealing plate 14 has a shape corresponding to the base plate 11. Only the height of the sealing plate 14 is less than that of the base plate 11. In particular, the sealing plate 14 also has openings 140 which are aligned with the openings 111 of the base plate 11 in the assembled state of the protective device. That is, armature 110, which serve to secure the protective device in the ground, engage both through the openings 111 of the base plate 11 and through the openings 140 of the sealing plate 14.
