Description

The invention relates to a separation module for a transportable modular lane separation system having the features of claim 1. Furthermore, the subject of the present invention is also a separation module having the features of the preamble of claim 9.

Transportable modular lane separation systems, ie lane separation systems, which consist of a plurality of respective frontally interconnected, mutually movable, in particular pivotable separation modules are generally known. These lane separation systems are used to separate lanes on motorways with separation modules similar to guardrail systems from each other. Accordingly, such a lane departure system is a guards on roads as well as a guard rail system or a concrete wall.

It is known, for example, to put individual separation modules together to form a modular lane separation system ( WO 2011/088485 A1 ). This requires the use of a crane on site.

The modular lane departure system from which the invention is based has long been known ( EP 1 327 028 B1 ). The separation modules of the traffic lane separation system are each connected to one another at the end via the mutually engaging connection elements. This results in a transportable and in particular laterally displaceable chain of the separation modules. Specifically, adjacent separation modules are pivotally connected by a bolt that is inserted through hinge components attached to the ends of each adjacent pair of separation modules. The lane separation system consisting of the plurality of separation modules connected to one another is normally mounted on the roadway in a floating manner.

A special feature of the aforementioned portable modular lane separation system is that the mutually coupled separation modules can be successively raised by means of a module transfer machine and laterally offset in raised form. The according to the road course self-propelled module transfer machine has inside an elongated S-shaped transfer channel in the right and left Anheberollen rollers or rollers are arranged, which take a T-shaped head of the mutually coupled separation modules and thereby lift the respective separation module something of the roadway ,

The module transfer machine slowly advancing in the direction of the road lifts the separation module for the separation module and moves the chain of separation modules serpentine in the transfer channel, ie along the elongated S-curve so that the chain of separation modules at the exit of the module transfer machine is gently set down again, but now compared to the entrance is laterally offset by a desired amount.

Such a module transfer machine has the great advantage that a transportable, modular lane separation system can be displaced laterally over a considerable distance in a very short time. As a result, for example, in a construction site, depending on the time of day, a lane located between lanes of opposite directions of travel can be switched from one to the other direction of travel by assigning them to the lanes of the other direction of travel.

The technique described above has been known for a long time. Also known for a long time are separation modules for such a modular lane separation system.

A separation module of a lane departure system initially has an elongate longitudinal sides and short end faces having major part. This usually consists of reinforced concrete, ie reinforced concrete. It usually has uphill and slightly inclined running towards each other, possibly even once or several times stepped longitudinal sides. These are connected by short end faces, so that face the end faces of adjacent separation modules.

The construction described above is initially independent of whether the portable modular lane departure system is one in which a crane is used to handle the separation modules, or one in which the module transfer machine described above finds application.

Instead of being made of reinforced concrete, the main part can in principle also be made of metal (see the above-described WO 2011/088485 A1 ). For the present applications, however, reinforced concrete is the preferred material for the manufacture of the main part due to the high resistance.

Separation modules for such modular lane separation systems must be able to be used in everyday driving direction independent. However, it has been shown that the separation modules known from practice and from literatures are consistently less suitable for a collision in one direction of travel than for a collision in an opposite direction of travel. The teaching of the invention is therefore based on the problem of specifying a separation module for a portable modular lane separation system, which is the best possible independent of the direction of travel used.

Another problem with a portable modular lane departure system is the lateral offset of the mutually coupled separation modules upon impact of a vehicle. This lateral offset should be as low as possible. In that regard, the teaching of the invention is also based on the problem, a separation module of the type in question in such a way that it has independent of direction of travel a lowest possible lateral offset at a defined impact.

The previously indicated problem of the direction of travel independent applicability of the separation module is achieved in a separation module with the features of the preamble of claim 1 by the features of the characterizing part of claim 1.

According to the separation modules on both sides, that is convex on both end faces in the longitudinal direction, that is curved outwardly curved. As a result, sharp edges and corners on the end faces in the transition to the longitudinal sides of the separation modules are systematically avoided. The curvature to the outside can be designed continuously arcuate. But it can also be designed in the manner of a polygon. Particularly preferably, the shape is circular arc convex.

Practice has shown that such corners and edges on the one hand bring with it the risk that stuck there body parts of an impacting vehicle and thereby trigger uncontrolled movements of the vehicle as a whole. On the other hand, it has been shown that such corners and edges break away on the main parts of the separation modules and thereby also offer a significant source of danger. These corners and edges are inventively avoided. The end faces of the separation modules are designed to be convex in the longitudinal direction, which would not have to be functionally formed due to the required pivotability of the separation modules against each other.

Preferred embodiments and further developments of this teaching of the invention are subject matter of claims 2 to 8.

It has already been stated above that although the main part can be made of metal, it is preferably made of reinforced concrete because reinforced concrete allows a higher inert mass to be realized. Also known compounds of reinforced concrete and metal for the main part of the separation module.

Particularly preferred installation dimensions for the main part of the separation module are evident from claim 3. These installation dimensions are of particular interest for use in connection with a module transfer machine.

With regard to the embodiment of a preferred variant of the connecting elements, further references emerge from claim 4.

So far, all aspects of this invention relate to separation modules that are positioned with a crane, as well as separation modules that can be positioned with a module transfer machine. Specifically for use in a module transfer machine, although of course in any case can also be positioned with a crane, according to claim 5, that on the main part of this upwardly extending, over the full length of the main part extending upper part is formed or, preferably, attached and that the upper part forms for itself or together with an upper region of the main part on both sides longitudinally extending undercuts. The upper part may be formed directly on the main part on the one hand. Then it is in a main part made of reinforced concrete itself also made of reinforced concrete (as the example in EP 1 327 028 B1 ). But the top can also be a separate, permanently connected to the main body component (for example EP 1 936 036 B1 , there in particular Fig. 10). In this case, the upper part is preferably made of metal.

It is essential that the upper part forms for itself or together with an upper portion of the main part on both sides longitudinally extending undercuts. In the undercuts, for example, take the Anrollenollen or rollers of the module transfer machine. Of course, the undercuts can in principle also serve the attack of a pair of wrenches.

For the resilience of the entire lane departure system claim 6 is essential. Not only the main parts of adjacent separation modules, but also the tops of the adjacent separation modules are coupled together at both ends. This is done in the connection elements of the upper parts according to the same principle as in the connection elements of the main parts, namely with a lower connection element on a separation module and an overlying, in substantial coverage thus located connecting element of the adjacent separation module.

Particularly preferred in terms of a good interchangeability of individual separation modules from the stationary chain is an opposite arrangement of the connecting elements on the upper part on the one hand and on the main part on the other.

Finally, for further embodiments and preferred structural details reference is made to the explanation of the preferred embodiment.

A sibling solution of the above-described problem is the subject of claim 9, which may find in a particularly preferred teaching also in conjunction with the teaching of one or more of claims 1 to 8 use.

Thereafter, the stability of the separation module is improved by a particularly suitable pad of rubber or a rubber-plastic mixture. In itself, such "anti-slip plates" are known. This is about how the anti-slip plates are attached to the separation module.

Finally, the subject of the invention is a portable modular lane separation system as such, which consists of a plurality of the separation modules described.

Fig. 1 shows in plan view the principle of a module transfer machine 1 for the lateral offset of a lane separation system of the type in question.

You can see in Fig. 1 in the body of the module transfer machine 1, whose own direction of travel is indicated by the arrow, right an input of a transfer channel 2, indicated by dashed lines, and left above an output of the same transfer channel 2. In the module transfer machine 1 is a second, mirror image extending transfer channel 2 '. This serves a lateral offset of the lane separation system in the opposite direction.

In a preferred embodiment, the module transfer machine 1 has a total of slightly more than the width of a lane. The lateral offset of the lane separation system by means of the module transfer machine 1, which in Fig. 1 can be seen, so in a preferred embodiment of such a module transfer machine 1 amount to about the width of a lane.

With reference to FIG. 1, it is readily apparent how the individual separation modules 3 of the lane separation system are picked up by the slow drive of the module transfer machine 1 in the lower right direction and laterally offset slowly and deposited on the top left.

In order to allow the method explained above to proceed, the module transfer machine 1 has at the edges of the transfer channels 2 on both sides corresponding delivery rolls or rollers 4, which are indicated schematically here. Thus, the individual separation modules 3 of the lane separation system are raised slightly from the road so that they can be freely displaced laterally. How this is done in detail will be explained in more detail below.

In principle, the teaching of the invention is also applicable to a portable modular lane separation system, in which the separation modules 3 are not offset by means of the module transfer machine 1 shown, but in which a crane individual separation modules 3 settles where they are needed.

Fig. 2 shows a chain of interconnected separation modules 3 in side view. Fig. 3 shows two such separation modules in side view and Fig. 4 shows this in top view. The Fig. 2 to 4 will be considered in the context below.

Each separation module 3 has elongated longitudinal sides and short end faces on a main part. 5

Let's go to it now Fig. 8 in connection with the other, mentioned figures.

The main part 5 has at the first end side a lower portion 6 and a contrast, in the longitudinal direction recessed upper portion 7 and at the second end side, a lower portion 6 'and in contrast, in the longitudinal direction before jumping upper portion 7'. This construction is chosen, in particular by their dimensions, that the lower and upper sections 6, 7 of adjacent separating modules 3 can be brought together in substantial overlap.

In the lower and upper sections 6, 7 each connecting elements 8 are provided for horizontally pivotable connecting adjacent separation modules 3. These will be discussed in more detail below.

It is essential first, that, in particular Fig. 4 shows, both the lower portions 6 and the upper portions 7 on both end sides in the longitudinal direction convex, here and preferably in particular circular arc convex shaped. 3 and 4 combined with Fig. 2 let's see well in context, that no corners and edges are formed in this way. No matter in which direction of travel a vehicle approaches the lane separation system at an angle, it always encounters an outwardly curved end section of the respective separation module 3. This has the advantages explained in the general part of the description. It should be noted that under certain circumstances, the convex shaping can be done by a design of the end faces in the manner of a polygon.

In the illustrated and preferred embodiment, it is provided that the main part 5 of the separation module 3 consists of reinforced concrete. But there are also main parts of separation modules known, which consist of metal. Combinations of reinforced concrete and metal in various sections or areas of the main part 5 of a separating module 3 are known from the prior art and can be used in principle here (see the references mentioned in the general part of the description).

To get an idea of the dimensions that are typically at issue here, it may be mentioned that according to a preferred teaching, the main part 5 has an effective installation length of 150 to 250 cm, preferably 200 cm, and / or a maximum width of 25 to 50 cm, preferably from about 30 to 40 cm, and / or a height of 60 to 90 cm, preferably from 65 to 80 cm, in particular from 70 to 75 cm.

The end-to-end connection of the main parts 5 of the separation modules 3 with each other, thereby realizing the complete modular lane separation system, can be done in various ways. Typically, a connecting rod is used, with which a pivotable connection of adjacent separating modules can be realized. Depending on the design length compensation devices are still seen before, which can be carried out in various ways. For this purpose, reference may be made to the prior art explained in the introduction.

The illustrated and preferred embodiment shows, with regard to the connection of the adjacent separation modules 3, that the connection elements 8 have connection openings 8 ', which are arranged in the lower and upper sections 6, 7 so that they are aligned with each other at overlapping sections 6, 7 and by means A connecting rod 8 "and / or connecting sleeve introduced there can be coupled to one another. The reference numerals 6 and 7 are also correspondingly at the appropriate place for the reference numerals 6 'and 7'. Fig. 3, 4 and 6 show well the details of the connection technique described here,

However, the separation module 3 according to the invention for a portable modular lane separation system has not only a main part 5, preferably made of reinforced concrete, but in the illustrated and preferred embodiment, also another part, namely an upper part 9. It is namely provided that on the main part 5 a this after top extending, over the full length of the main part 5 extending upper part 9 is formed or, preferably, is mounted and that the upper part 9 forms on its own or together with an upper portion of the main part 5 on both sides longitudinally extending undercuts 10. The illustrated and just so far preferred embodiment shows that the upper part 9 is actually attached to the main part 5. It is therefore a separate construction, which is attached here by appropriate, anchored in the reinforced concrete of the main part 5 fixing screws 11.

In principle, however, it is also possible for the upper part 9, as has already been mentioned above in the prior art, to be formed in one piece with the main part 5, in particular of reinforced concrete.

It is essential that the upper part 9 forms on its own or, as here, with the upper region of the main part 5 on both sides of the longitudinally extending undercuts 10, behind which the Anrollenollen or rollers 4 of the module transfer machine 1 (Fig. Fig. 1 ). The same applies to the possibility of attacking a crane forceps.

In order that the chain of the modular lane separation system which is decisive for the resistance during a vehicle collision is not interrupted even in the region of the upper part 9 of the separation modules 3, the preferred teaching is that the upper part 9 of the separation module 3 has a connection element 12 at both front ends. Based on Fig. 4 and in connection with it Fig. 7 It can be seen that in the illustrated and preferred embodiment, the upper part 9 is not made of reinforced concrete, but of metal, namely a multi-folded metal sheet. In Fig. 5 you can see a frontal view from the left in Fig. 3 , It can be seen above the folded metal upper part 9 and in solid lines the lying, lower metallic eyelet, which forms the connecting element 12 at this point. Concealed overhead is indicated by dashed lines located at the far end, overhead sleeve which forms the connecting element 12 of the upper part 9 there.

In Fig. 6 is the cut in Fig. 3 placed so that it passes exactly through this area of superimposed fasteners 12. It can be seen that the two connecting elements 12 are aligned with one another at mutually facing end sides of adjacent separating modules 3 and are here connected together with the connecting rod 8 ", which also connects the connecting openings 8 'of the main parts 5. Thus, a connecting rod 8 is used "and / or connecting sleeve coupled both the connecting elements 8 to the main parts 5 and the connecting elements 12 at the tops 9 adjacent separation modules 3 at the same time with each other.

For reasons of the best possible interchangeability of adjacent separation modules 3, the embodiment shown in FIGS still shows that after particularly preferred teaching at the end with the projecting upper portion 7 'on the main part 5, the connecting element 12 on the upper part 9 is in the lower position and at the end with the recessed upper portion 7 on the main part 5, the connecting element 12 on the upper part 9 is in the upper position.

The entire chain of separation modules 3 forming the modular lane departure system is shown Fig. 2 ,

Out Fig. 8 and Fig. 9 recognizes in conjunction with each other another feature of the present invention, which also has independent significance. It is provided there, in fact Fig. 8 indicated by dashed lines, that at least one base plate 13 is attached to the underside of the main part 5, which is attached to the underside of the main part 5 steel frame 14 and inserted into the steel frame 14, attached to the steel frame 14 and from the steel frame 14 down considerably outstanding Non-slip plate 15, preferably made of rubber or a rubber-plastic mixture having. Such an anti-slip plate 15 made of rubber or a rubber-plastic mixture, which may also be fiber-reinforced or metal-reinforced, is in itself for such an application nothing special. It is essential, however, that here the steel frame 14 this anti-slip plate 15 carries. This is therefore not directly attached by means of appropriate fasteners on the bottom of the main part 5. It is rather attached to the steel frame 14 and this is fixed to the underside of the main part 5 with corresponding fastening screws 16. As a result, the slip-resistant plate 15 is largely relieved of lateral shear forces. These are introduced in any case over much larger areas in the steel frame 14.

It is particularly useful if the slip-resistant plate 15 is glued into the steel frame 14.

In Fig. 8 one sees the bottom of the main part 5 of the separation module with slightly upwardly curved water drainage openings 17. The bottom surfaces formed therebetween of the main part 5 are each provided with a corresponding base plate 13 according to Fig. 9 Mistake.

In principle, it is also possible to perform the base plate 13 exclusively as an anti-slip plate made of rubber or a rubber-plastic mixture and stick directly to the underside of the main part 5 of the separation module 3.
