Definitions

  • the invention relates to a drivable roundabout island, the is prefabricated and assembled on site from individual parts can, can therefore be described as transportable.
  • Roundabouts enable and have a high level of security statistically little and, above all, almost only minor accidents.
  • the speed level is low and the traffic is nevertheless - albeit slowly - on the road and rarely stops.
  • the roundabout island is used by cars such as roundabouts and heavy goods vehicles to drive like an intersection. Heavy goods traffic runs over the Roundabout island.
  • the island is in the form of a spherical cap educated. It represents the central element of the roundabout because it is only through them that the node becomes Roundabout recognizable.
  • roundabout islands that can be driven over are permanently placed and were on site through paving, asphalt structures and concrete.
  • the circular island diameter is at least 4 m.
  • the production of such roundabout islands is not possible and conditional within a very short time high manufacturing costs, not least due to the considerable amount of work on site.
  • a transportable traffic island is known from DE-OS 29 05 769, which can also be driven over. It is made up of a large number of individual parts plugged together so that a structural unit is formed. she lies flat on the road due to its own weight not anchored in the road.
  • the traffic island is preferably there made of elastic material or epoxy.
  • the traffic island are a multitude of elements for determining its edge curve in conjunction with a variety of Connection plates, which the inner surface determined by the edge curve fill out, required. To when crossing the traffic island damage to the motor vehicles, in particular the tires or to prevent the wheel suspension, it is intended to retrofit external, wedge-shaped elements.
  • the invention proposes an existing traffic island from several plate-shaped elements raised to the center of the island, the on the pavement or one placed in the pavement, rest on the island diameter adapted, and several Locking elements for the traffic island that are aligned Recesses in the elements and the pavement or the Push through the recess made in the pavement.
  • the roundabout island It is essential in the roundabout island according to the invention that it is made from as few components as possible. This requirement is however, from the point of view that the individual plate-shaped Elements transported and assembled in an acceptable manner can be. It is considered particularly advantageous if four identical, each extending over a quarter circle, plate-shaped elements are used. Because when driving over the roundabout island by means of heavy motor vehicles not only considerable forces perpendicular to the road surface in the plate-shaped Items are initiated, but as a result of the increase of the elements also in the level of the road surface, is by the locking elements shift the roundabout island effectively prevented. The locking elements provide the form fit of the elements to the road surface Roundabout island not directly on the road surface, but in a recess adapted to the island's diameter.
  • the upper surface of the radially outer area in an approximately aligned position surrounding road surface are brought so that the tires of the heavy vehicles only over a fairly low level or else do not drive up a step onto the roundabout island and therefore axial Shock forces absorbed by the locking elements would have to be minimized. It is considered to be particularly advantageous if between the recess made in the pavement and no circular gap remains in this roundabout island. In principle, however, this can be present.
  • the outside diameter the roundabout island and the diameter of the depression but should be adapted so far that the motor vehicles immediately from the lane surrounding the traffic island to the traffic island drive.
  • the elements and / or the locking elements is considered plastic, especially recycled plastic.
  • the trafficable roundabout island can be used with Recycled plastic can weigh a ton.
  • the locking elements as Cylinder are formed, and the cross sections of the depressions Cylinder diameter are adjusted.
  • the elements are for example formed as molded parts that are directly perpendicular to the support plane of the elements positioned cylindrical openings are. These are adapted to the diameter of the locking elements.
  • the use of the locking element made of plastic, recycled plastic in particular enables each Form locking element as a shear wedge. Should, out whatever the reason, too much force on the plate-shaped Elements are exerted, thus breaking or tearing the plate-shaped elements avoided because the shear wedge breaks beforehand. When repairing, only the shear wedge needs to be replaced.
  • the respective plate-shaped element is preferably in a central one Area and / or in adjacent plate-shaped elements adjacent areas with the plate-shaped element penetrating Provide recesses.
  • the locking is therefore not only in the central, but also in edge or corner areas of the plate-shaped Elementes, wherein a locking element with several plate-shaped elements interacts. This ensures that not only by means of the respective plate-shaped element of the locking element is fixed, but also several plate-shaped Elements among themselves.
  • This method makes it possible in a simple manner and in particular within a short time, the support for the roundabout island to manufacture and anchor them.
  • a cut is made that is deeper than the intended one Support position of the roundabout island.
  • the difference measure is by means of a subgrade, especially mastic asphalt, backfilled. This is ensures that an absolutely flat surface for supporting the plate-shaped Elements of the roundabout island is generated.
  • the level Contact surface is a prerequisite for the plate-shaped elements, which consist in particular of plastic when driving over do not break using heavy motor vehicles.
  • the diameter the milling is adapted to the outer diameter of the traffic island, so that they are preferably inserted into the recess with little play can be.
  • the traffic island is then locked with the area of the Subgrade. For this it is sufficient to drill holes for the locking elements to be brought into the formation and, if necessary, the pavement.
  • Figure 1 shows the situation after the conversion of a conventional road intersection to the roundabout using the passable Roundabout island 1. This is concentric to the intersection of the two crossing streets and has a diameter from about 4 m. The two crossing streets are with the Reference numbers 2 and 3 denote. Concentric to the roundabout island 1 are markings 4 relating to the roadway width for conventional ones Motor vehicles and the circumferential direction of the roundabout island 1 attached. The illustration shows that large Vehicles, especially heavy goods traffic, the rather narrow radius of the Roundabout can not follow and especially if he the Leave the roundabout in a straight or left turn direction would, as a rule, be required, the roundabout island 1 to run over.
  • This roundabout island 1 consists of four in the exemplary embodiment identical, extending over the sector of a quarter circle plate-shaped elements 5.
  • each element 5 points in the region of the intersection its two right-angled legs 6 have a recess 7, which describes the contour of a quarter circle.
  • About half way through Length of the respective leg 6 is the respective element 5 with a provided further recess 8, which has the shape of a semicircle has. This is in the area of the bisector of the element 5 finally, approximately half the radius with a recess 9 provided that has a circular cross section.
  • the radius of the Circle of this recess 9 corresponds to the radius of the rest Cutouts 7 and 8.
  • Figures 2 and 4 to 6 in particular illustrate the anchoring the trafficable roundabout island 1, which in this embodiment directly on the surface 10 of the road surface 11 rests.
  • this embodiment relates to a Variant in which the street intersection when converting into a roundabout not be changed in the area of the roundabout island got to.
  • the four individual elements 5 of the roundabout island 1 are in In the sense of the representation in Figure 2 placed on the road surface 11 and there are in the area of the circular recesses 9 in the elements 5 and the circular recesses 12, which are in the area of lined up elements 5, the recesses 7 and 8 assigned arise, inserted as a cylinder formed locking elements 13, holes 14 previously made in the road surface 11 enforce circular cross-section.
  • the diameter of the locking elements 13 is slightly smaller than the diameter of the circular recesses 9 and 12 or holes 14 in the pavement. But it is also conceivable that the locking elements 13 have a slightly larger diameter so that they after assembly under a certain preload the plate-shaped Allocate elements 5 or holes 4 in the road surface 1.
  • Figure 7 shows a modified embodiment in which the roundabout island 1 not placed directly on the road surface 1 but in the area provided for roundabout island 1 is, first, the road surface 11 in the upper area is milled out. Then to smooth the milled area there is a subgrade, in particular a mastic asphalt layer 15. The depth of the cutout is such that, as in FIG. 7 is illustrated, the surface of the formation 15 is lower than the surface 10 of the non-milled area of the pavement 11.
  • the surface of the milled area of the pavement 11 is the reference number 16, the deepening on the roundabout island 1 hung up and designated by the reference number 18.
  • Figure 7 illustrates that the diameter of the roundabout island 1 the diameter of the milled area of the pavement 11 corresponds.
  • the respective plate-shaped Element 5 a more upward section 17, which is particularly provided with a marking so that the Roundabout island 1 can be optimally recognized by traffic.
  • this section 17 increases the wall thickness of the respective Element 5 towards the center of the roundabout island 1, the slope angle, as can be seen from the illustration in FIG. 7 to the horizontal, is only slight.
  • Figure 5 illustrates the detail of the locking of the respective element 5 with its support for the two in FIGS. 4 and 7 shown use cases.
  • the road surface 1 passes through the respective locking element 13 the formation 15 and also partially the pavement 11.
  • the laying planum is produced the road surface is milled 4 cm. A smooth, clean one To maintain the formation, approx. 2 cm of mastic asphalt is placed. After embarrassment the roundabout island 1 in the recess 18 is the edge poured clean with mastic asphalt. The thickness of the plate-shaped Element is between 5 and 12 cm. To lay the plate-shaped elements 5 using a light assembly crane be gripped laterally.
