Definitions

  • the invention relates to a curb according to the preamble of claim 1.
  • a polymeric curb formed to the exact dimensions of a semi-tapered or rounded concrete curb as defined by the European standard prEN1340.
  • a part of said polymeric curb is made of a polymeric material with a lower density and has at least one longitudinal hole therethrough.
  • Such polymer curbs are critical for recycling, e.g. when dismantling or renovating a road, since they are regularly removed with concrete residues adhering to the foundation, so that sorted recycling is only possible if the adhering concrete residues are manually removed from the polymer curbs or their fragments are removed. This means an extremely increased amount of work.
  • the curb according to the invention comprises a top surface, a a roadway-facing front side surface, a rear side surface opposite the front side surface, a left side surface and a right side surface, a bottom surface, and a cavity and a ceiling arranged between the cavity and the top surface, wherein the curb is made of concrete, the Cavity opens to the floor surface and wherein the ceiling has a thickness which corresponds to at least 15% and at most 25% of a height of the curb.
  • the curb has a stability that is almost comparable to that of a curb made of solid material when driving over it with high loads, but it is still significantly lighter than a curb made of solid material and can be easily recycled together with adhering concrete residues, since these are also made of concrete is made.
  • the cavity is surrounded laterally by a front side wall forming the front side surface, by a rear side wall forming the rear side surface, by a left side wall forming the left side surface and by a right side wall forming the right side surface, the left side wall and the right side wall each have a wall thickness which is at least 1.5 times as thick as a wall thickness of the front side wall or a wall thickness of the rear side wall at a comparable height.
  • the cavity has at least 20% and in particular at least 30% of a volume defined by the outer dimensions of the curb.
  • the weight of the curb is reduced by at least 20% and in particular at least 30% compared to a concrete curb with comparable dimensions. This makes handling easier, reduces transport costs and reduces energy consumption and raw material consumption.
  • a front side wall, a rear side wall, a left side wall and a right side wall of the kerbstone taper towards the ceiling towards the cavity by at least 20%.
  • the curb in the upper area of the side walls is particularly resistant to buckling, so that it can also absorb loads that can occur if the rim of a vehicle wheel hits the curb, to a comparable extent as curbs made of solid material without breaking.
  • a front side wall, a rear side wall, a left side wall and a right side wall of the curb merge into the ceiling, forming a radius of at least 10 mm and in particular at least 20 mm. This also stabilizes the curb in the upper area of the side walls.
  • the curb is in the form of a straight curb which, in addition to the cavity, also comprises at least one further cavity.
  • enlarged contact surfaces can easily be formed between a left and a right edge area of the curb, so that undesirable bending stresses can be avoided by at least one further enlarged contact surface in a central area, particularly in the case of longer curbs.
  • the curb is in the form of a curved curb, with a front side face of the curved curb and a rear side face of the curved curb running equidistant from one another. Since the proportion of road surfaces to be delimited with curved kerbstones is large, further significant CO2 savings can be achieved through the manufacture of such curved kerbstones.
  • enlarged contact surfaces can easily be formed between a left and a right edge area of the curb, so that undesirable bending stresses can be avoided by at least one further enlarged contact surface in a central area, particularly in the case of curbs with a large arc length.
  • a first section of a lateral surface of the at least one cavity is designed as a one-dimensionally curved surface.
  • the cavity can be adapted to the shape of the front side surface or the rear side surface, so that a constant thickness of the front side wall or the rear side wall towards the cavity is ensured and chess points are thus avoided.
  • the cavity can be adapted to the shape of the front side surface and the rear side surface, so that a constant thickness of the front side wall and the rear side wall towards the cavity is ensured and chess points are thus avoided.
  • the first and the second section run equidistant from one another.
  • the at least one cavity or all cavities can be adapted to the curve that the curved curb stone has in plan view of its ceiling, so that both the front side surface and the rear side surface are in the area of the cavity or in the areas the cavities constant thickness of the front side wall and the rear side wall is guaranteed, so that the curved curb has a constant stability in the area of the cavity or in the areas of the cavities.
  • a curb is both a straight curb—also referred to as a straight curb—understood whose opposite side faces are parallel are aligned to each other, as well as a curved curb - also referred to as curved curb - understood, the front side surface and the rear side surface are equidistant to each other.
  • a curb 1 according to the invention is shown in a side view.
  • a contour of a cavity 2 of the curb 1 is indicated with a dashed line L.
  • the figure 2 shows a sectional view through the in the figure 1 shown curb 1 according to the section line II-II.
  • the curb 1 comprises a top surface 3 which is formed by a cover 4 . Furthermore, the curb 1 comprises a front side surface 5 facing towards a roadway FB, which is formed by a front side wall 6 . The curb also includes a rear side surface 7 opposite the front side surface 5 and formed by a rear side wall 8 . Likewise, the curb 1 includes a left side surface 9, which is formed by a left side wall 10, and a right side surface 11, which is formed by a right side wall 12. Finally, the curb 1 comprises a floor surface 13 which runs around the cavity 2 in the manner of a ring. The cavity 2 is surrounded by the top surface 3 and the walls 6 , 8 , 10 , 12 supporting the top surface 3 . The curb 1 is made of concrete B. The cavity 2 opens towards the bottom surface 13 .
  • a thickness D4 of the ceiling 4 is approximately 18% of a height H1 of the curb 1.
  • the left side wall 10 and the right side wall 12 each have a wall thickness D10, D12 which, at a comparable height, is at least 1.5 times as thick as a wall thickness D6 of the front side wall 6 or a wall thickness D8 of the rear side wall 8.
  • the cavity 2 has a volume V2 which corresponds to approximately 33% of a volume V1 defined by the outer dimensions of the curb 1 . This weighs in the Figures 1 and 2 shown curb 1 instead of about 312 kg only about 208 kg.
  • the front side wall 6, the rear side wall 8, the left side wall 10 and the right side wall 12 of the curb 1 widen from the bottom surface 13 to the ceiling 2 out in a wedge shape in the direction of the cavity 2 by at least 20%.
  • the front side wall 6, the rear side wall 8, the left side wall 10 and the right side wall 12 of the curb 1 each merge into the ceiling 2, forming a radius R6, R8, R10, R12 of about 20 mm.
  • the curb 1 has a length L1 of about 1.2 m and a width B1 of 0.25 m, the height H1 being about 0.45 m.
  • the outer dimensions of the curb 1 are the length L1, the width B1 and the height H1.
