Definitions

  • the invention relates to a Betonleitwand for road boundary.
  • Concrete guide walls for road boundary have a concrete body. Within the concrete body usually several longitudinally extending reinforcing elements in the form of steel cables or the like are arranged. Such concrete protection walls are for example in DE 10 145 647 and DE 10 2005 030 412 described.
  • Such concrete guide walls are made for example as in-situ concrete baffles.
  • the first plurality of reinforcing elements are arranged for example on or next to the roadway.
  • the individual longitudinally adjoining reinforcing elements overlap each other or are usually joined together by welding.
  • the production of the concrete guide wall, within which the reinforcing elements are arranged takes place mechanically as in-situ concrete guide wall.
  • the reinforcing elements are lifted by the machine to be brought into the exact later horizontal and vertical position.
  • the concrete wall is made by casting by means of concrete.
  • joints are provided during the manufacturing process of the concrete guide wall. Such joints are usually provided at a distance of four to six meters. These joints must be filled after hardening of the concrete, for example, with elastic joint material. Despite such elastic filling of the joints leaks may occur especially after several years, leading to the ingress of water and thus to corrosion of the reinforcing elements.
  • the object of the invention is therefore to provide a concrete barrier to the roadway boundary, which has a long service life.
  • the concrete guide wall according to the invention for road boundary has a concrete body.
  • the reinforcing elements extend in particular in the longitudinal direction of the concrete body. To avoid corrosion of the at least one reinforcing element this is encased according to the invention. Due to the sheathing of the at least one reinforcing element according to the invention, it is ensured that, despite the penetration of water, there is no corrosion which impairs the stability of the reinforcing element.
  • the sheath according to the invention need not extend over the entire length of the at least one reinforcing element. Rather, it may be sufficient to provide appropriate sheathing in particularly vulnerable areas. These are, in particular, also joints provided with in-situ concrete guide walls, which are provided to compensate for shrinkage, the occurrence of temperature fluctuations, etc.
  • the sheathing is a plastic sheath.
  • the plastic coating comprises polyolefins, in particular polypropylenes, polyethylenes, mixtures thereof or copolymers.
  • the at least one reinforcing element may be a reinforcing element having a plurality of strands.
  • the plurality of strands are connected by twisting, braiding or the like to a reinforcing element, for example.
  • at least a part of the strands is encased, which in particular is again a plastic casing, as described above.
  • the reinforcing elements in particular having a plurality of strands, preferably comprise steel and, in a particularly preferred embodiment, are made of structural steel.
  • the concrete body can be a concrete body produced as a sideways concrete wall. This is produced directly on site by appropriate machines. Alternatively, it may also be mobile concrete guide walls. Such mobile concrete guide walls are used, for example, to delineate construction sites or in the area of road boundaries, which must be openable.
  • the concrete guide wall preferably has a stepped and / or flared cross-section.
  • the Betonleitwand is thus narrower at an upper side than at an underside.
  • the concrete guide wall has a head part, wherein the head part extends in particular over a height of 50% - 60% of the total height of the concrete guide wall. Measured by an upper edge, the head part preferably has a height of 40 cm - 60 cm, preferably 45 cm - 55 cm. It is further preferred that within the head part at least two, and more preferably at least three, reinforcing elements are arranged. It is particularly preferred that an upper reinforcing element has a distance from the upper edge of the head part of at least 10 cm, in particular at least 15 cm.
  • Another second reinforcing element seen from above preferably has a distance of 10 cm-15 cm from the upper reinforcing element. It is particularly preferred that a third reinforcing element in the head part is provided, which in turn to the second reinforcing element has a distance of 10 cm - 15 cm.
  • the at least two, in particular three reinforcing elements in the head part are arranged horizontally one above the other in a plane.
  • the movement elements are preferably in the longitudinal direction at least partially, preferably completely, around coated reinforcement elements.
  • the reinforcing elements are preferably arranged in a vertical plane or vertically superimposed.
  • the head part of the concrete guide wall according to the invention preferably has a width of 20 cm to 30 cm extending transversely to the longitudinal direction of the concrete guide wall.
  • the concrete guide wall according to the invention preferably has a foot part which has a width of 50 cm to 70 cm, preferably 55 cm to 65 cm, on a footprint.
  • the footprint is the underside of the Betonleitwand on which the Betonleitwand is set up or arranged, for example, on the road or on a concrete foundation or other type of foundation.
  • the foot part preferably has a height of 30 cm - 50 cm.
  • an approach is arranged on the footprint, which may optionally also have a greater width.
  • the approach projects into a groove of corresponding dimensions provided in the foundation, the road surface or in a concrete foundation or the like.
  • the approach preferably has a height of at least 4 cm, in particular at least 6 cm.
  • the groove Transverse to the longitudinal direction of the concrete guide wall, the groove has a width of at least 20 cm, in particular at least 30 cm, particularly preferably at least 35 cm.
  • the approach preferably has no interruption.
  • a retention level of H2 can be achieved. This can be achieved in particular with an overall height of the concrete protective wall of about 90 cm.
  • the concrete protective wall according to the invention may in particular be a concrete protective wall which is symmetrical with respect to a vertical plane, it being preferred that the reinforcing elements are also arranged in this plane.
  • a concrete protective wall is particularly suitable for lateral roadway boundary.
  • the concrete protective wall is formed as an asymmetrical concrete protective wall, wherein a pointing in the direction of the road front has a flared foot, similar to the symmetrical concrete protective wall.
  • the facing away from the roadway back has no such issued foot, but a particular flat, preferably inclined surface.
  • Such unbalanced concrete protection walls are particularly suitable for placement in the region of the central strip. It is particularly preferred that such concrete protection walls are arranged in the median strip of a highway with their backs facing each other.
  • the intermediate space of these concrete protective walls is preferably backfilled with soil or the like.
  • a concrete guide wall 10 may, for example, in Fig. 1 having outer contour shown, wherein the outer contours can vary depending on the type of Betonleitwand and the purpose of use.
  • the outer contours can vary depending on the type of Betonleitwand and the purpose of use.
  • three reinforcing elements 16 extending in the longitudinal direction are arranged in particular in an upper region 14 or a head part of the concrete body.
  • the longitudinal direction is perpendicular to the plane of the drawing.
  • the individual reinforcing elements 16 can, for example, as in Fig. 2 or Fig. 3 be constructed shown.
  • the individual reinforcing elements 16 have a plurality of strands 18, in particular made of steel. These are surrounded by a common casing 20. This can be, as in Fig. 2 shown to be a casting. Likewise, it is also possible that a tubular sheath is pushed as a jacket, for example, over the strands 18 and thus over the entire reinforcing element.
