Definitions

• the invention relates to a connecting device for connecting separating elements for traffic areas with two connecting elements, each having at least two juxtaposed legs, wherein in each case at least one leg of a connecting element between legs of the other connecting element is positively received by a leg of the received between legs of the one another connecting element on both sides has projections which engage behind projections which are arranged on the legs of a connecting element,
• the invention further relates to a separating element for traffic areas, which is preferably made of concrete, and has connecting elements on end faces, with which it can be connected to a subsequent separating element.
• Such a connecting device and such a separating element are known, for example, from CH 443387 A and EP 1 467 028 A.
• the connecting devices described there have, like many other known connection devices the disadvantage that they do not provide sufficient security against tearing apart. The reason is that the connecting elements or their legs abut against each other at wedge surfaces, which are arranged so that the legs of the connecting elements are pressed apart when acting by a collision of a vehicle with the interconnected via a connecting means separating elements, a force pulls the fasteners apart.
• the legs are at least partially supported by concrete laterally in order to prevent the bending away of a leg, which is actually possible only to a very small extent, since the concrete breaks out very easily in this corner area.
• the invention is therefore based on the object to provide a connecting device of the type mentioned and equipped with such a connection means separating element, in which the risk of tearing apart in a vehicle collision is lower.
• this object is achieved in that it is designed with a connecting device as stated above.
• the connecting device By means of the connecting device according to the invention, it is achieved that the legs are not pressed apart by the hook-shaped connection region when the tensile force acts on the connecting elements, but on the contrary they are held against each other or pulled towards each other.
• this causes the bending moments acting on the legs to be smaller, as a result of which the legs do not have to be made as solid as in the prior art.
• acting on the projections now bending forces, but which can be absorbed with much less material, since the bending moments are much lower due to the much shorter projections.
• shear forces occur in the region of the projections, which are also much easier to control than the large bending moments acting on the legs in the prior art.

• FIG. 8 shows a fourth embodiment of a connecting device according to the invention in FIG
• an inventive separation element 1 is shown, which can be used as known per se with other separating elements 1 for separating traffic areas, such as roads, but also any other surfaces. If a plurality of juxtaposed separators 1 are connected together, they can also be used as restraint systems, either between lanes or at the roadside.
• a connecting device 2 according to the invention is used which, in the embodiment illustrated in FIGS. 1 to 4, consists of two identical connecting elements 3. These connecting elements 3 are arranged on end faces 4 of the separating elements 1, wherein the arranged on opposite end faces 4 connecting elements 3 are rotated about a horizontal axis by 180 °, so that they occupy the position shown in Fig. 3.
• the connecting elements 3 shown in FIGS. 1 to 4 have two legs 5 and 6, which are connected via a web 7 with a plate-shaped holder 8.
• Leg 5 has at its end facing away from the bracket 8 two projections 9 and
• the second leg 6 has at its end remote from the bracket 8 end only a projection
• leg 6 which is turned to the other leg 5, so that the leg 6 with its projection 11 as a whole has an approximately L-shaped cross-sectional shape.
• the projections 9, 10 and 11 have to the holder 8 directed contact surfaces 12, 13, 14, which are aligned at an angle ⁇ less than 90 ° to a center plane 17 of the holder 8.
• angle ⁇ is between 60 ° and 95 °, ideally between 80 ° and 90 °.
• the projections 9, 10, 11 are hook-like arranged on the legs 5, 6.
• This tensile force tries to pull the legs 5 of the connecting elements 3 between the legs 5 and 6 of the other connecting element 3 out.
• the legs 5, 6 must be bent to the side, at the same time the transitions between the projections 9, 10, 11 and the legs 5, 6 are subjected to a combined bending and shearing force. Since the contact surfaces 12, 13, 14 are inclined at an angle of less than 90 ° to the pulling direction, the legs 5, 6 engage with their projections 9, 10, 11 into one another, so that a larger bending moment on the legs 5, 6 occurs only when the projections 9, 10, 11 so were deformed far that the angle ⁇ of the contact surface 12, 13, 14 has become equal to or greater than 90 °.
• the legs 5, 6 with their projections 9, 10, 11 can be performed very solid (at the same time relatively low use of material due to the small length of the legs 5, 6 and the projections 9, 10, 11), can be a significant part of the deformation force and deformation energy already from the projections 9, 10, 11 and their connection with the legs 5, 6 are taken before the legs 5, 6 are bent significantly. Since the legs 5, 6, as the drawings show, can also be made relatively short and at the same time relatively low use of material massive, these also have a very high bending resistance and are able to absorb high lateral forces.
• this construction of the connecting elements 3, a connecting device 2 which has a very high resistance to pulling apart of the connecting elements 3 in the event of a collision of a vehicle.
• the brackets 8 are connected via webs 7 with the legs 5 and 6. In order to have the most symmetrical load or force distribution on the connecting elements 3, the brackets 8 are arranged on the webs 7, that the center plane 17 is in the region of the contact surfaces 13 of the two lying in the middle of the connecting device 2 leg 5.
• the legs 5, 6 and their projections 9, 10, 11 are designed with strongly rounded edges and corners, so that the connecting elements 3 can easily slide into one another. In addition, this facilitates their manufacture and reduces the mechanical stresses in the region of the corners in the event of a collision of a vehicle with a separating element 1.
• the length ratios of the legs 5, 6 and the projections 9, 10, 11 are preferably selected such that the ratio of the length X of the legs 5, 6 and the length Y of the projections 9, 10, 11 is between 0.5 and 2.0.
• connecting rods 20 are secured to the top 18 and the bottom 19 of the brackets, preferably welded.
• the connecting rods 20 may, for example, be made of rib-gate steel commonly used in construction and connect a connecting element 3 on one end face 4 of a separating element 1 to the other connecting element 3 on the other end face 4. But it is also conceivable that the connecting rods 20 do not pass from one to the other connecting element 3, but after a certain length in the interior of the separating element 1 ends.
• These connecting rods 20 can of course also two or be arranged several times on the side surfaces of the brackets 8.
• vertical grooves 21 extend in the region of the connecting elements 3 on the front side 4, which create a free space for the leg 6 of the connecting element 3 arranged on the adjoining separating elements 1.
• a coupling element 22 is shown, in which two connecting elements 3 are connected directly to each other. This means that they are connected to each other either immediately after their webs 7 or via a short support member 8.
• Such coupling elements can be used to provide a slightly greater distance between two separating elements 1, for example, to be able to set up lighter dividing elements 1 in curves with a smaller radius of curvature than would be possible with directly interconnected separating elements.
• a connecting element 23 has two T-shaped legs 24, which is designed as the leg 5 of the embodiment of FIG. 1 to 4.
• the second connecting element 25 has a middle leg 26 and two outer legs 27.
• the middle leg 26 is again like the middle leg 5 T-shaped and the outer legs 27 are designed as the leg 6 of the embodiment of FIG. 1 to 4 L-shaped.
• the advantage of this embodiment is, on the one hand, that the connecting elements 23, 25 are completely symmetrical with respect to the center plane 17, which lies in the plane of the holders 8, and, on the other hand, that there are now a total of three legs 24, 26 which are in Connection with their projections have a T-shaped cross-sectional shapes, which allows a symmetrical loading of the legs 24, 26 and distributed the load on a larger number of legs 24, 46, 27 and a larger number of projections.
