Abstract

The traffic lane divider comprises interconnected concrete elements (1) with each connecting member (3) comprising a J-shaped anchor plate forming a hook (4) which at its free end extends halfway into the socket chamber (6) for the connector of the adjoining concrete element. The socket chamber can have a square cross-section and the part of the hook protruding over the end face corresponds in length to the depth of the socket chamber.

Description

Rail separation device.

The invention relates to a device of lane separation for braking, reconduction or stopping of vehicles that deviate from the road, consisting of elements of concrete, preferably the same shape, that are going to arrange along the road or between its rails, juxtaposed in the longitudinal direction and joined together, than in their front surfaces aligned perpendicular to the direction longitudinally they are provided with union members anchored in the interior, which are applied to each other when concrete elements they are placed next to each other joined by the front, being each connecting member formed by an anchor plate shaped J in cross section thus constituting a hook, which by its face that presents the hook has an angular profile, constituting the space between the angular profile and the hook a chamber of housing for the connecting member of the concrete element adjacent.

A rail separation device of this type is known by the document DE-U-296 14 929, which has given extraordinary results in practice. A decisive point in these rail separation devices is that they can be transported to the place of employment as prefabricated parts, where can be aligned with each other with the help of union members to form a solid set. In front of those devices of separation of lanes that are prepared in place for example with the help of sliding formwork and transport concrete, these they offer the advantage that they can be used flexibly, and in Particularly they are also reusable.

In addition, the document FR-A-2 598 484 already shows a form of realization of a rail separation device made with hooks.

In particular cases, particularly with charges extremely high, in rail separation devices known problems may occur that under extreme load the hooks open to the point that it is no longer guaranteed completely hooking each other, so that the consequence It can be a separation of concrete elements. This in general should not be the result of a single charge; rather the consequence of several successive efforts may be the combat of the hook, which eventually leads to such a deformation of the hook, that mutual engagement is no longer enough.

The invention aims to improve a rail separation device of the type mentioned at principle, so as to avoid effectively combating the hook.

This object is carried out according to the invention. extending the free end of the hook to the chamber of accommodation, so that the hook cannot leave the accommodation, even when it is combated under high load.

The advantage achieved by the invention consists in essentially in that with the aforementioned loads the hook experience as before a slight deformation, although often only elastic, since the wall of the housing chamber limits the deformation path possible. To that we must add that between free end of the hook and wall of the housing chamber is extends the hook of the adjoining concrete element, thereby an extremely solid buttress is achieved for the end free from the hook. Since this is a system with positive union of absolute strength, no elements needed additional compared to comparable systems.

It has been especially advantageous and is preferred in the context of the invention, that the free end of the hook extends to about half the depth in the housing chamber. In this configuration you always have a sufficient safety tolerance that prevents the combustion of hook even with extreme loads.

It is favorable in this context in relation to the spatial dimensions that the housing chamber has a approximately square cross section.

It has also been advantageous that the part of the hook protruding from the front surface corresponds to its length approximately to the depth of the chamber of accommodation.

Finally, in regards to the ability to maximum load, the width of the housing chamber should correspond to approximately four to five times the thickness of the anchor plate. Under these dimension specifications there is as before the possibility of having two elements of adjoining concrete also with little gap between each other or arrange these with a small angle to each other, which is also possible align the arc-shaped concrete elements along curves of the road.

The following will explain in detail the invention in an exemplary embodiment represented in the drawing; show:

Fig. 1, a concrete element shown only partially in section with a connecting member;

Fig. 2, two concrete elements arranged one next to each other and united to each other; Y

Fig. 3, the content of Fig. 2, but with distance from each other of the concrete elements.

The rail separation device represented in the drawing serves for braking, reconduction or detention of vehicles leaving the road. This device Rail separation consists of concrete elements 1 that are going to be arranged along the road or between their lanes, which are juxtaposed in the longitudinal direction and are joined each. These concrete elements 1 preferably have The same way.

On its front surfaces 2 aligned perpendicular to the longitudinal direction, the elements of concrete 1 are provided with union members 3 anchored in the interior, which are applied to each other when concrete elements 1 are placed next to each other joined by the front.

Each connecting element 3 consists of a plate J-shaped anchor in cross section thus forming a hook 4. This anchor plate carries on the face that presents the hook 4 an angular profile 5, finishing the free arm of the profile angular 5 flush with the front surface 2 of the concrete element 1 and, therefore, the space between the angular profile 5 and the hook 4 it constitutes a housing chamber 6, which serves for the housing of the connecting member 3 of the concrete element 1 adjacent.

As shown in particular from Fig. 1, the free end of the hook 3 extends to the chamber of accommodation 6. This ensures that the hook 3, even when it is combated by being subjected to high load, it cannot leave by the accommodation chamber 6, as indicated by the strokes in Fig. 1 and is designated by the number 7.

As can also be seen from Fig. 1, the free end of hook 4 extends to approximately the half the depth inside the housing chamber 6. In addition the housing chamber 6 has a cross section approximately square

It can also be recognized without more than the part of the hook 4 protruding from the front surface 2 of the element of concrete 1 corresponds approximately in length to the housing chamber depth 6.

The dimensions are chosen otherwise that the width of the housing chamber 6 corresponds to approximately four to five times the thickness of the plate anchor, as can be recognized in Fig. 2. As result is therefore enough slack to also in case of small adjustment inaccuracies ensure smoothly the Assembly of individual concrete elements 1. But nevertheless, the distances of the hooks 4 from each other or the hook 4 of the accommodation chamber walls 6 are so small that they are only possible slight deformations of the hooks 4. Particularly in in case of a high load the free end of the hook 4 is deposited relatively fast on the other hook 4 which in turn rests on the housing chamber wall 6, so that as a result a combination and, therefore, a separation of the Concrete elements from each other.

In Fig. 3 are the two concrete elements 1 adjacent ones arranged with the maximum distance from each other, where you can see that even in this position a combination is excluded of the hooks 4. There is also a sufficient clearance for align the two concrete elements 1 - unlike the representation in Fig. 3 - under a small angle, so there is the possibility of following an arc-shaped course of the road.
