Definitions

  • the simpler roadway separation devices include foils that are glued to the roadway or colored strips that are sprayed on the roadway. These roadway dividers only work visually.
  • the more complex lane dividing devices include marking nails, which are fastened in rows on the lane. At first, these also have a visual effect. If the wheels of a passing vehicle touch the marking nails or even run over them, this is also noticeable for the vehicle driver through rhythmic shaking of the vehicle and usually also through roaring noises emanating from the tires and amplified by the vehicle body.
  • These roadway separating devices are either very flat, as in the case of the foils or the colored strips, or they have a very low height of approximately 10 to 30 mm, as in the case of the marking nails.
  • marking nails In addition to the simple marking nails in the form of a spherical section, there are also such marking nails that are equipped with a flag-like attachment made of a flexible material. All of these traffic facilities, namely the flat foils or colored strips, and also the marking nails, even those themselves with essay, but can only guide traffic visually. They are unable to prevent them from crossing the road boundary marked by them.
  • a spatial separation of oncoming traffic is possible with a known lane separation device, the individual elements of which have base parts with a trapezoidal cross-section, on which steel posts are attached at certain intervals, and a protective barrier is attached to the upper end of each. Due to the standard dimensions of the guardrails, this road dividing device is at least 4 m long. For this reason and because the lane dividing device is composed of steel parts, it has a relatively high weight. They are therefore only suitable for construction sites that remain unchanged in the same place for a long time. Due to its high weight and large dimensions, this roadway dividing system can only be transported with special vehicles with a crane and both set up and dismantled. In this roadway antenna device is also disturbing that its base width is about 1 m. This roadway separating device can therefore only be used at those construction sites where, in addition to the roadway antenna device, there is still a sufficient area as usable area for the roadways and the large area loss of the roadway separating device is thus bearable.
  • Another known roadway separating device also has individual elements which have a base with a trapezoidal end face, to which an at least approximately cuboidal back part adjoins at the top. These individual elements are placed one behind the other. They are designed as hollow plastic bodies, so that they can be transported more easily and are easier to set up and dismantle. To increase their own weight, they are fed with fiber at the installation site filled.
  • a steel rod is arranged in its interior in its longitudinal direction, which protrudes through the end wall on both end faces of the components.
  • a coupling device for coupling two components standing one behind the other in the longitudinal direction is a U-shaped steel bar section which is screwed to the steel bar with the back of its web.
  • both flange parts of the coupling part there is a through hole, which are aligned with each other in the vertical direction on both flange parts.
  • These coupling parts are mounted at different heights on both end faces of a component, so that when a number of components are lined up, the flange parts of the coupling parts can overlap one another at a small vertical distance.
  • a connecting bolt is inserted into the through holes of the coupling parts of two adjacent individual elements, which are then aligned with one another, by means of which the two adjacent individual elements are coupled to one another in the longitudinal direction and in the transverse direction.
  • An end section is angled on the connecting bolt, with which it rests on the uppermost flange part.
  • This roadway separating device has the disadvantage that its individual elements are made of plastic as hollow bodies, which require filling to increase their own weight. This filling can consist of water. Then the individual elements can not be used at temperatures below freezing, or the water filling must be mixed with expensive antifreeze. Another complaint is a sand filling.
  • the water filling In the case of a water filling, the water filling must be sucked out of each individual element when the roadway separating device is dismantled and disposed of if it is provided with an antifreeze. It could only in the warm season Water fill can be drained into the environment without antifreeze. A sand filling must be taken out of the cavities so that the weight of the individual elements is not so great. But the sand filling must be dry so that the filling is free-flowing. For emptying, the individual elements must be turned upside down so that the sand filling can trickle out at least for the most part.
  • This known roadway separation device has the major disadvantage that its coupling devices on the end face, with the flange parts projecting in the axial direction, result in a considerable clearance between the end faces of two adjacent individual elements.
  • both the base walls and the side walls of the cuboid-shaped back part do not form a coherent surface, as is the case, for example, in roadway dividing devices with protective planks, but are constantly interrupted within a short distance of approx. 1 m by the gaps between two adjacent individual elements.
  • the gaps have a considerable length of approx. 20 cm.
  • the invention specified in claims 1 and 2 is based on the object of providing a roadway separation device which enables adequate physical separation of the vehicle streams traveling in opposite directions along it and which is more robust in use and more manageable in construction and dismantling than the known vehicle separation devices.
  • the base bodies are designed as solid bodies, they have a far higher dimensional stability than a hollow body with a given strength of the material made of the same plastic, even if it has a flowable or free-flowing filling.
  • the coupling device is formed on the one hand by a T-groove on each of the two end faces of the base body and on the other hand is formed by a coupling part with an I-shaped plan, half of which is on the T-shaped plan the T-slot is matched in the base bodies and the height does not protrude above the height of the T-slot, so that two adjacent base bodies can and must be joined together until their end faces touch.
  • the coupling device each has a coupling rod running in the vicinity of the end face of the base body transversely to its longitudinal extension, which extends through the recess on the end face of the base body and in that the second coupling part is designed as a coupling bracket , which has a coupling hook at each of its two ends, with which it can be attached to a coupling rod of the abutting base body, also allows a seamless stringing together of the base body and at the same time ensures that the base body can be coupled with each other even more easily and quickly. Due to the interaction of metal coupling parts, this coupling device has a higher strength than in the first embodiment.
  • both lane dividing devices it is achieved that when a vehicle approaches at an acute angle, the vehicle wheels can roll up onto the roof surface of the sole part on the side of the vehicle facing the lane dividing device.
  • a certain steering effect is achieved by the entering inclined position of the vehicle, which directs the vehicle away from the roadway separation device.
  • the wheel load of the wheels rolling on the sole part loads the relevant round body in addition to its own weight and presses it onto the road. This reduces the risk that the carriageway separating device will be pushed aside by the ascending vehicle and thus pushed into oncoming traffic.
  • the manufacturing costs of the roadway separation device are significantly reduced.
  • the dimensional stability of the individual elements in the longitudinal direction is considerably increased, so that they can absorb considerable forces in the longitudinal direction of the entire lane separating device, which can arise, for example, that a certain section of the lane separating device from a vehicle to the side is pressed, thereby increasing the longitudinal stress on the individual elements concerned, similar to the transverse loading of a tensioned rope.
  • the coupling bracket of the coupling device can always remain at one end of the base body, the coupling bracket can be folded up for transport or for setting up and dismantling, so that it is completely in the recess on the The end face of the base body disappears, and that it can simply be folded down in the operating position of the base body and, with its free hook end, engages behind the coupling rod of the adjacent base body and thus the coupling of the two base bodies takes place in a very simple and quick manner.
  • the coupling bracket slides down after swiveling into its rest position under the effect of its own weight until it sits on the coupling rod with the profile leg of the guide leg then standing horizontally.
  • the coupling bracket By engaging the longitudinal section of the coupling bracket below the coupling rod on the rear wall of the recess, the coupling bracket automatically secures itself in this position under the effect of its own weight.
  • it only has to be pulled up on the hook of the upward end until the other hook lies against the coupling rod, and then swiveled downwards in the direction of the adjacent base body, in order then again under the effect of its own weight into the Swivel the coupling position.
  • the hook of the coupling bracket also rests in a central region of its inner surface on the coupling rod of the adjacent base body when the two base bodies are aligned obliquely to one another at a certain angle, as is the case with the installation is the case along a curved lane.
  • the base body can also be set up along a curved line without the middle regions of the end face of the base body with the coupling devices being moved apart because of the corners of the base body located on the inside of the curved line.
  • the carriageway separating device can be equipped with an initial ramp, seen in both directions of travel, by means of which head-on collisions with the carriageway separating device are avoided.
  • the carriageway separating device according to claim 13 By designing the carriageway separating device according to claim 13, it is possible to achieve a greater overall height of the carriageway separating device with the attachment bodies, without the basic bodies alone having to have this structural height.
  • the individual parts of the two layers By dividing the total height of the lane separation device into two layers, namely once in that of the base body and once in that of the attachment body, the individual parts of the two layers still have a sufficiently low weight with a predetermined total height of the lane separation device.
  • the guide elements make it easier to put the attachment bodies on and for them to operate given some guidance at the same time.
  • a further development of the carriageway separating device according to claim 14 ensures that the attachment bodies can be placed on the base bodies offset by half a length with respect to these.
  • An embodiment of the roadway separating device according to FIG. 15 creates guide elements which are relatively simple to form and at the same time effective and which also allow a certain inclination of the individual elements when they are set up along a curved line. The same is achieved with guide elements in an embodiment according to claim 16.
  • the placement of the attachment body on the base body is facilitated because a certain centering effect emanates from the inclined side surfaces.
  • the roadway separating device With an embodiment of the roadway separating device according to claim 18, it is possible to releasably connect the attachment bodies with the base bodies in a detachable manner, so that the two layers of the individual elements form a unit, so to speak.
  • a very robust and easy-to-use fastening device is created, of which no parts protrude outwards in the operating position of the individual elements of the lane dividing device.
  • this roadway separating device according to claim 20 it is also achieved that when the fastening screws on the attachment bodies are not screwed into a fastening nut on a base body, the fastening screws are therefore in their rest position, the fastening screw is still completely inside the attachment body . As a result, the Transport of the attachment body and when handling the attachment body excluded that the screw thread is damaged.
  • the possibility is also created to temporarily connect the attachment bodies to the base bodies, the connection being established very quickly.
  • this roadway separating device according to claim 22 it is also ensured that the toggle rod is completely within the attachment body in the idle state, and that when handling the attachment body the lower end of the toggle rod cannot be damaged with the toggle pin.
  • this roadway separating device ensures that in the rest position of the toggle rod, its toggle pin always assumes a very specific rotational position with respect to the attachment body, so that with a corresponding adjustment of the alignment of the perforated disks to the base bodies, the toggle pin immediately by simply depressing the toggle rod can enter the recess of the perforated disc and then the toggle bar only has to be turned a quarter turn to make the connection.
  • a further development of the roadway separating device according to claim 24 ensures that the toggle rod assumes the correct pivot position in relation to the recess in the perforated disc in the locking position even without special attention of the operator, in which its toggle pin is at least approximately at right angles to the long-round shape of the recess in the perforated disc is aligned.
  • the toggle rod can also - not accidentally turn out of the coupling position into such a rotary position in which its toggle pin is aligned with the recess in the perforated disc, whereby the connection of the attachment body with the Basic bodies would be practically solved.
  • the support surface for the head of the fastening screw or the toggle rod is formed by a metal part, which also ensures an intimate connection of this support surface with the attachment body through its molding in the base of the attachment body, through which higher forces can also be absorbed and transmitted.
  • the guide tube is able to absorb greater lateral forces than the base material of the attachment body when the fastening device is loaded laterally.
  • a connecting device is created which, in addition to fastening the attachment parts to the base bodies, also assumes the mutual guidance of these parts, the top side of the base body and the underside of the attachment body outside the connecting device being able to be smooth and flat. This increases the area of contact between the two bodies.
  • the part of the connecting device arranged on the base body can be easily and safely molded into the material of the base body directly and without the aid of other molded parts.
  • the roadway separating device according to claim 31 By designing the roadway separating device according to claim 31, a relatively simple to produce and easy to use guide device is created, which also takes over the function of an anti-rotation device without additional parts. With the design of the roadway separation device according to claim 32, a robust and at the same time reliable connection of the attachment body with the base body is made possible.
  • the reflectors make it easier to recognize the roadway separation device at night and thus indirectly improve the service life of the roadway separation device.
  • the roadway separating device 40 is formed by a number of mutually identical base bodies 41 which are detachably connected to one another at their end faces 43 by means of a coupling device 42 and thereby form a coherent chain.
  • the base bodies 41 have an elongated, at least approximately rectangular outline shape. Their end faces 43 are angled on both sides of the central plane of the base body 41 by a certain angle with respect to a normal plane to the central plane. This helix angle is approximately half as large as the maximum swivel angle by which a base body is pivoted in relation to the adjacent base body in the combination of the roadway separation device 40 when the roadway separation device is set up along a curved line. This helix angle is therefore at least approximately equal to half the apex angle of that circle sector which is drawn from the center of curvature of the curved line of installation to the two end faces of a base body 41.

In reality, however, it is advisable to choose the width of the coupling bracket 87 only so much smaller than the clear width of the recess 83 between the longitudinal struts 86 of the reinforcing frame that the coupling bracket 87 has just the lateral space and the freedom of movement that is necessary so that two mutually adjacent base bodies 81 can be aligned obliquely to one another on a curved installation line. Within the scope of this movement space, the clamping bracket 87 is then able not only to transmit longitudinal forces, but also to effect a certain guidance of the base bodies 81 with one another in the lateral direction.

In this way, protruding edges are avoided in such a setup.
  • attachment bodies 112 are only loosely placed on the base bodies 111 and they rest thereon only under the effect of their own weight, it is also expedient to equip the attachment bodies 112 on their end faces with coupling devices 125 which are designed similarly or identically to the coupling devices 126 of the base body 111 (Fig. 26 and Fig. 28). Because of their simple handling and, at the same time, safe coupling, coupling devices such as coupling devices 82 (FIGS. 16 ... 18), which are provided with a coupling bracket 87 or with the modified coupling bracket 101 (FIG. 22), are particularly suitable.
  • the coupling devices 125 of the attachment bodies 112 can be omitted and the attachment bodies can thereby be made simpler if the base bodies 127 and their attachment bodies 128 are connected by means of two fastening devices 129, which are indicated in FIG. 27 by a broken line.
