Definitions

  • Planting islands serve, for example, to calm traffic, improve traffic flow and increase traffic safety.
  • they are designed in particular as roadway dividers or rondels, they improve the flow of traffic, in particular by enabling roundabouts without traffic lights and increase traffic safety, in particular by creating speed funnels or protected crossings.
  • the road surface has been used to form planting islands when redesigning existing traffic routes the area of the planting island is torn open and high curbs are arranged adjacent to each other in the recess created in the area of the outer contour of the planting island.
  • the space enclosed by the high curbs is filled with earth, the island created in this way can then be planted.
  • a disadvantage of such planting islands is that the traffic area required by them has to be completely redesigned, which also necessitates a change in the drainage in this area.
  • the planting islands are arranged at the edge of the road, without a drainage guide specially adapted to the position of the planting island, the rainwater would build up in the area of the planting island.
  • Another disadvantage is that it is not possible to dismantle such a plant island without considerable construction.
  • a plantable trough for gardens formed from individual parts is known, the individual parts being screwed together.
  • the parts are designed as angle elements, the surfaces arranged perpendicular to one another form the trough edge and the trough bottom, the surfaces being each rectangular.
  • the angle elements lie with their trough bottom directly on the ground and the individual angle elements are screwed at a distance from the trough bottom, so that narrow drainage channels running perpendicular to each other are formed below the screw connection.
  • a raised traffic island is known from DE-A-29 05 769.
  • the edge and the outer floor area of the traffic island are formed by individual, side by side and adjacent angular elements, which are designed differently according to the outer contour of the traffic island.
  • the inner floor area of the traffic island is formed by thick plate elements.
  • the angle elements and the plate elements have feet on their undersides and are fastened to one another or positively connected.
  • the plate elements close off at the top with the angle elements and are of relatively large design, that is to say each plate element extends between opposite edge regions of the traffic island.
  • the field of application of the planting island according to the invention is particularly in the area of traffic calming, improving the flow of traffic and increasing safety in traffic seen, but is not limited to this. It is also conceivable, for example, to use the planting island where it is important to beautify the surroundings, for example on paved, unoccupied places.
  • Plant island should not only be understood to mean a plantable structure in an island arrangement, but also an arrangement in an edge area, for example on the roadside.
  • potting soil should not only be understood to mean soil, but also other materials that are suitable for representing a plantable subsoil.
  • the trough can be formed from individual components, namely the angle elements and the plate elements.
  • the individual, primarily standardized angle elements allow any desired circumferential shape of the planting island to be specified, the plate elements bridge the floor area between the angle elements.
  • road breaks can be dispensed with entirely, which permits short assembly times for the planting island and largely prevents traffic.
  • the trough is designed to be raised due to the feet arranged on the underside of the angle elements and the plate elements, surface water can run off unhindered over the road surface without it being dammed up by the plant island.
  • the trough of the planting island is made up of individual components, it can be easily dismantled and reassembled at another location.
  • the system is therefore not only inexpensive, but also extremely flexible. Lined like flat roof greenery and filled with soil, the stable planting islands can be greened excellently. They are largely maintenance-free.
  • the angle elements and the plate elements consist of plastic, in particular of recycled plastic.
  • the angle elements and plate elements made of plastic can be used to produce all types of planting islands with arches, circles, curves and straight lines.
  • the shape of the shaped pieces can be processed by grinding or cutting so that troughs of any shape can be formed.
  • the design of the angle elements in such a way that they form the trough edge and the outer trough bottom area ensures an optimal hold of the angle elements without the need for an independent connection thereof.
  • the weight of the potting soil not only rests on the plate elements, but also on the outer trough bottom area of the angle elements.
  • the respective angle element can be provided on its side facing away from the outer trough floor area with a floor-side projection which serves as impact protection for vehicles. If a collision of a vehicle with the planting island is so severe that the components of the planting island are shifted against each other, they can be quickly straightened or replaced if damaged.
  • the design of the angle elements in such a way that their outer trough bottom area, seen in plan view, tapers towards the inner trough bottom area, allows standardized angle elements to be arranged in a concave arc.
  • the respective angle element has a trapezoidal shape in its outer trough bottom region, in particular the shape of an isosceles trapezoid, the trapezoid tapering towards the inner trough bottom region. The maximum curvature of the trough edge formed by the adjacent angular elements is then given when the adjacent angular elements lie against one another in the region of the trapezoidal legs.
  • a first design of the bottom projection provides that it has a projection surface in the form of a rectangle and the length of the rectangular side facing the outer trough bottom area corresponds to the length of the long parallel side of the trapezoid of the angle element assigned to the outer trough bottom area. Adjacent angular elements can thus be arranged at an obtuse angle to the planting soil filling, with a more or less large opening wedge between the adjacent projections on the bottom.
  • a second design of the base-side projection provides that it has a projection surface in the form of a trapezoid, in particular in the form of an isosceles trapezoid, which tapers to the outer trough bottom region, and the length of the short parallel side of the trapezoid assigned to the projection corresponds to the length of the long one parallel side of the trapezoid assigned to the outer trough bottom area.
  • angle elements designed in this way straight lines can no longer be formed, but only more or less curved concave polygonal arches.
  • the aim is to standardize those angle elements whose bottom-side projection has the trapezoidal cross-sectional area so that concave arches of medium curvature can be achieved with the angle elements. Those arches that have a lower curvature can then be formed by the angle elements in which the base-side projection has a rectangular contact surface, while for arches with a larger concave curvature the angle elements are twisted, the base-side projections of which have the trapezoidal cross-sectional area.
  • the size of the acute angle of the isosceles trapezoid assigned to the projection should be greater than or equal to the size of the acute angle of the trapezoid assigned to the outer trough bottom region. In particular, the size of the acute angle is considered to be greater than 60 °.
  • each angle element advantageously has a height of 30 to 70 cm, in particular 50 cm, a width of 30 to 70 cm, in particular 50 cm and a length of 50 to 150 cm, while the Plate elements expediently have a rectangular shape, in particular a size of 50 cm wide and 100 cm long.
  • the feet of the angle elements and the plate elements have a height of 5 to 10 cm.

  • the plate elements 3 have a rectangular shape in plan view, wherein they are cut in the area of the adjacent angular elements 2 in accordance with the predetermined inner circular shape.
  • FIG. 2 shows an essentially oval arrangement of the angle elements 2 with the plate elements 3 filling the area enclosed by them. While the circular design of the trough 1 according to FIG. 1 represents the basis for a planting island in the literal sense, the essentially oval design of the trough takes place 1 Use as a planting island on the side of the road, i.e. the straight area 1a of the trough 1 is arranged in the area of the rain drainage groove of the street adjacent to the curb of the sidewalk.
