Description

The invention relates to a device for connecting a first mobile protective wall element to a second mobile protective wall element according to the preamble of claim 1.

Protective wall constructions made of a plurality of individual protective wall elements are known to the person skilled in the art and are preferably used to secure traffic routes, in particular for temporary or permanent stationary securing in the area of construction sites, workplaces and roads or the like. They are also used to protect against or against off-road vehicles and to protect persons or special facilities adjacent to a road.

The publication DE 20 2011 104 387 U1 discloses a generic device for connecting mobile protective wall elements. This device is T-shaped, wherein a horizontal component extends below the protective wall elements and a vertical component is oriented at right angles to the horizontal component. Both components of the device are firmly connected.

This device has the disadvantage that it is relatively heavy, whereby the assembly or disassembly of a mobile protective wall is very force or personnel-intensive and therefore expensive.

It is thus the object of the present invention to provide an improved, in particular lighter, device for connecting a first mobile protective wall element to a second mobile protective wall element, which is just as stable and functionally reliable as the known connecting device.

The solution of the aforementioned object is achieved by a device for connecting a first mobile protective wall element with a second mobile protective wall element according to the subject matter of claim 1.

The device according to the invention for connecting a first mobile protective wall element to a second mobile protective wall element comprises a first connecting means, which is preferably designed as a longitudinally extending rail or as a longitudinally extending rail element, and a second connecting means which is arranged at least two at a predetermined distance from each other having parallel wall parts. By means of the first connecting means and the second connecting means, the first mobile protective wall element and the second mobile protective wall element to each other in a predetermined orientation fixing active compound can be generated, wherein the first connecting means at least partially below the first mobile protective wall element and at least partially below the second mobile protective wall element in one first coupling region for forming a connection between the first mobile protective wall element and the second mobile protective wall element can be arranged. The second connection means can be arranged in a second coupling region extending orthogonally to the longitudinal direction of the first connection means between the first mobile protective wall element and the second mobile protective wall element. According to the invention, the first connection means and the second connection means are designed as separate components and thus can be arranged at a distance from one another.

This solution is advantageous since, in order to produce a load-compatible coupling between the two mobile protective wall elements, they do not have to be completely coupled to a common connecting means at the end, as a result of which a significantly shorter and therefore lighter connecting means can be used. Furthermore, the device according to the invention is much more advantageous to transport and store, since their components are individually transportable or storable, which also facilitates handling at the installation.

This advantage results in particular, but without limitation, in mobile protective wall elements which have laterally widened profile elements in their lower installation area (installation surfaces) and which therefore can be set up independently, without having to rely on the coupling with a widened bottom plate of the connecting device in the sense of Umkippschutzes ,

In a further embodiment of the present invention, the rail element is at least partially formed by extending in the height direction Wandungsanteile, which can be brought into contact with the mobile protective wall elements in the first coupling region, wherein the wall portions preferably consist of a first wall portion and a second wall portion, wherein the first wall portion of the rail element or the rail and the second wall portion of the rail for forming an upwardly open profile exclusively on the underside by a further wall portion of the rail are interconnected.

This embodiment is advantageous since a rail with an open profile can receive the mobile protective wall elements in a form-fitting manner in a simple manner. This results in an easy to disassemble and to mount arrangement.

According to a further preferred embodiment, the first wall portion of the rail and the second wall portion of the rail for forming a closed profile on the underside and top side, in particular by means of further Wandungsanteile, connected to each other, wherein the closed profile is preferably a hollow profile.

An advantage of this embodiment is that a hollow profile allows a very rigid rail shape, whereby the maximum load capacity is increased compared to an open profile.

In terms of a further preferred embodiment variant, the rail has a multiplicity of connecting points, in particular holes, wherein at least one connecting point can be assigned to the first mobile protective wall element and at least one further connecting point can be assigned to the second mobile protective wall element.

Furthermore, according to another embodiment of the present invention, the connecting means can be arranged at a predetermined distance to the rail element, wherein the connecting means is preferably positively and / or materially connectable with at least one mobile protective wall element, preferably by means of a welded connection.

This is advantageous because the connection means can be arranged in this way in a manner that is suitable for loading and optimized with respect to simple assembly / disassembly.

According to a further preferred embodiment of the present invention, the two wall portions of the connecting means in the second coupling region are weldable to at least one mobile protective wall element.

This embodiment is advantageous because the connecting means can be arranged captive on the first or second mobile protective wall element in this way.

In a further embodiment variant of the present invention, the connecting means on at least one guide element for receiving a Verspannmittels or Anpressmittels, in particular a screw, wherein the guide element is preferably a tubular means which connects holes introduced in two opposite wall parts together.

This embodiment variant is advantageous because the contact pressure is defined and protected attached in this way, whereby an unwanted premature failure of the pressing means, for. B. as a result of incorrect installation or environmental influences is prevented.

Furthermore, the invention is directed to a protective wall as a whole. This protective wall comprises at least a first mobile protective wall element and a second mobile protective wall element. In this case, the first mobile protective wall element and the second mobile protective wall element are connected to one another by means of a device according to the invention, wherein the rail element in a first coupling region, preferably below the form-fitting, with the first mobile protective wall element and the second mobile protective wall element in contact, and wherein the connecting means in a second coupling region is in contact with the first mobile protective wall element and the second mobile protective wall element, preferably frontally positively, and wherein the first contact region extends in a first direction, which is aligned orthogonally to the extension direction of the second contact region. The rail element and the connecting means are formed as separate components and spaced from each other.

The openings 45 . 46 are aligned in the installation or set-up each in a substantially horizontal plane.

In 7c is a plan view of two mobile protective wall elements 2 . 4 shown, wherein the second mobile protective wall element 4 with the second connection means 8th in contact and from the first mobile protective wall element 2 is spaced. The second connection means 8th is on a boundary wall 62 of the frame part 15 arranged. The boundary wall 62 preferably forms together with the first and second frame walls arranged thereon 50 . 51 (see also 3 ) a U-profile or a double-T-profile of the frame part 15 out.

In 8a is indicated by the area marked with the letter B, that in the 8b imaged arrangements are attributed to the designated location.

In 8b Four different embodiments are shown. The two embodiments arranged on the left have the second connection means already described above 8th on, the one having tubular body. In the upper of the two left representations are compared to the lower illustration on the mobile protective wall elements 2 . 4 each support on both sides 17 arranged. According to the lower left illustration are such support elements 17 but not mandatory. A support can, for example, via the first connection means 6 (see. 1 ) respectively.

According to the right in the 8b illustrated embodiments, the second connecting means 8th exclusively from the mutually substantially parallel wall elements 10 educated. The wall elements 10 are not directly connected to each other, but positively, positively and / or cohesively to the frame part 15 attached, in particular welded.

Corresponding to the left upper illustration, the mobile protective wall elements 2 . 4 in the upper right variant support elements 17 on, which are not provided in the lower right variant.

In 9a is a first example of a concrete embodiment of the first connection means 6 shown. This connecting agent 6 points between the support elements 16 a rail-like share 7 on, by two substantially in the Z-direction extending, but slightly inclined relative to the Z-direction wall portions 26 . 28 and two this wall proportion 26 . 28 each in an upper portion and / or in a lower portion connecting horizontal Wandungsanteile 32 is trained. The first and second wall part 26 . 28 are also arranged inclined to each other. The other wall sections 32 each extend in a horizontal plane and have connection points 36 or holes, in particular holes of different sizes.

This in 9b shown first connecting means 6 is essentially the same as in 9a shown first connecting means 6 , One difference, however, is that the first and second wall portions 26 . 28 are aligned parallel to each other.

In 9c is yet another first connecting means 6 shown. According to this embodiment, the rail-like portion 7 only by three wall parts 26 . 28 . 32 educated. The first and second walls 26 . 28 are aligned substantially or exactly parallel to each other. The one with the reference number 32 marked wall portion in this case has the reference numeral 36 indicated holes on.

In 10a is a side view of an extendable protective wall of elements 2 . 4 shown. The arrow C symbolizes the viewing direction for a variety of in the 10b and 10c shown frontal views of the first connecting means 6 ,

In 10b is a side view of a first connecting means 6 and a plurality of different frontal views a-d of the first connecting means 6 shown. Furthermore, two frontal views e-f different trained frame parts 13 the mobile protective wall elements 2 . 4 shown. The frontal view of the first connector marked "a" 6 has a rail-like portion, which forms a substantially rectangular cross-section. The walls 26 and 28 are preferably identical. This applies preferably also for the walls 32 , which are arranged at a constant distance from each other (see. 9b ).

In the variant marked "b", the walls are 26 and 28 arranged inclined to each other (see. 9a ). It can be seen that the walls 26 and 28 are arranged clearly closer to one another in an upper region than is the case in a further or lower region. This leads to the wall elements preferably arranged parallel to one another 32 have different dimensions in the X direction.

In the example marked "c" is a just extending wall 32 provided by the two lower areas of an arcuate wall 27 connected to each other.

In the variant marked "d", the walls are 26 and 28 arranged inclined to each other so that they touch in an upper region. In a lower area is another wall 32 provided, which the two inclined walls 26 and 28 connect with each other. The walls preferably form 26 . 28 respectively. 26 . 28 . 32 a triangular or pyramidal profile.

The two frontal views "e" and "f" of the mobile protective wall element 2 . 4 differ only in that according to the variant "e" the Gegenwandungen 60 . 61 extend exclusively in the vertical direction, wherein according to "f" still supporting elements 17 connect (see. 7b ).

In 10c is also a frontal view "a" of a first connecting means 6 (see. 9c ) and a frontal view "b" of a mobile protective wall element 2 . 4 shown. The variant shown in "a" corresponds essentially to the one in 10a with "a" marked variant, if this without the upper wall 32 is performed. It is in "a" thus an open variant in which the two wall parts 26 and 28 yourself lie opposite and limit a receiving space in which a further body (the protective wall element) can be introduced.

The in through the wall parts 26 and 28 In a limited receiving space insertable body particularly preferably corresponds to the mobile protective wall element shown in "b" 2 . 4 , Contrary to the in 10b Variants shown in accordance with the in 10c variant shown a partial enclosure of the mobile protective wall element 2 . 4 through the first connection means 6 ,

In 11 are a first front view "a" and a second front view "f" of two first connecting means 6 shown. The frontal view labeled "a" is the same as in 10b with "b" designated variant. The frontal view labeled "f" is the same as in 10b with "a" designated variant.

Below the one with "a" ( 11 ) are frontal view with this connecting means 6 in contact and differently shaped mobile protective wall elements 2 . 4 shown. Accordingly, under the front view marked with "f" are shaped differently shaped mobile protective wall elements 2 . 4 also in states coupled to the first connection means ("f").

In example "b" forms the mobile protective wall element 2 . 4 a negative mold or complementary shape to the first connecting means 6 off and is without lateral support elements 17 executed.

In example "c" is the frame part 13 the mobile protective wall element 2 . 4 formed approximately omega-shaped and is connected to the first connecting means 6 in the vertical direction only in a relatively small area, which is essentially in the area of the lower wall 32 extends, in contact. Through the Omega shape forms the frame part 13 lateral support elements, wherein it is also conceivable that these support elements 17 extra on the frame part 13 arranged or can be arranged.

In example "d" is the frame part 13 partially negative to the first connection means 6 formed and is therefore in particular sections of the first connection means 6 flat on. The frame part 13 has on both sides of the rail-like element of the first connecting means 6 arranged and extending straight in the vertical direction Wandungsanteile, followed by the downwardly inclined to the vertical aligned Wandungsanteile. The inclined wall portions of the frame part 13 stand in surface contact with the wall elements 26 . 28 of the first connection means 6 , Furthermore, in this example, the support elements are designed such that they support the elements 16 of the first connection means 6 essentially or exactly completely overlay.

In the example labeled "e", the frame element is 13 completely negative to the first connection means 6 educated.

The example "g" corresponds functionally to the example "b", wherein only the shape of the rail-like portion of the first connecting means 6 is different.

The examples "h" and "i" have substantially or exactly negative to the first connecting means 6 trained frame parts 13 on. The frame parts 13 are also omega-shaped, with the resulting lateral support elements of the mobile protective wall elements in the example "h" only partially and in the example "i" substantially or exactly complete the support elements 16 of the first connection means 6 overlap.

In 12 are different embodiments of first connection means 6 and of frame elements 13 or mobile protective wall elements 2 . 4 shown. Arrows are indicated in the individual examples a-h, which indicate at which points the devices are in contact with one another or transmit forces to one another.

The example "h" can be taken from a previously not mentioned coupling variant. Here, a double "tongue and groove" connection is used. In the case shown is the mobile protective wall element 2 . 4 on the underside with a trapze-shaped groove 64 equipped, and the first connection means 6 has one to the groove 64 complementary spring 66 on. However, it is in principle possible to provide this arrangement of tongue and groove and vice versa.
