Definitions

  • the present invention relates to a concrete spacer for ensuring a desired, uniform concrete covering of the reinforcing steel with at least one fastening means for fastening it to the reinforcing steel.
  • the concrete covering of the reinforcing steel is primarily intended to protect it from moisture and thus corrosion.
  • Concrete spacers of the type mentioned are known, for example, from the German concrete calendar edition 1986, volume 2, page 477.
  • the known concrete spacers have a uniform height corresponding to the desired concrete covering dimension.
  • the fastener or fasteners for fastening it to the reinforcing steel are anchored in their interior and thus also within the concrete covering dimension.
  • any foreign body, as represented by the fastening means is disadvantageous within the concrete cover with regard to its tightness and is therefore undesirable there. This is particularly the case when a non-corrosion-resistant steel wire is used as the fastening means. This corrosion, which occurs within the concrete covering mass as a result of moisture penetrating from the outside, will eat itself directly through to the reinforcing steel itself.
  • This object is achieved according to the present invention in that in the case of a concrete spacer of the type mentioned at the beginning, at least one shaping which exceeds the desired concrete covering dimension in height is provided, and that the at least one fastening means is anchored in this at least one projection.
  • this or the fastening means are anchored completely outside the concrete covering dimension.
  • two projections are provided on both sides of the area in which the reinforcing steel comes to rest.
  • the concrete spacer according to the invention can be produced in the sense of an efficient production by extrusion, the shaping or the shapings resulting from a suitable choice of the profile or results without an additional operation.
  • the concrete spacer shown in the drawings is a profile rod section produced by extrusion of fresh concrete and subsequent subdivision of the pressed strand into individual sections with a substantially trapezoidal profile in its longitudinal direction L.
  • the concrete spacer shown On its upper side OS, the concrete spacer shown has on both sides of the area on which the reinforcing steel BS rests on it a molding A1 or A2 which exceeds the desired concrete covering dimension H in height. These projections extend through the uniform profile of the concrete spacer shown A1 and A2 evenly along its longitudinal direction L and form a groove between them.
  • the concrete spacer of FIG. 1 and FIG. 2 has a steel wire SD as the fastening means. This is approximately in the area of half the length of the concrete spacer transverse to its longitudinal direction L horizontally at the level of the concrete covering H above the bottom US of the concrete spacer, cutting the bottom of the rings, through the two projections A1 and A2.
  • the two ends of the steel wire SD with eyelets protrude outwards beyond the concrete spacer.
  • two steel wires SD1 and SD2 can also be used, one steel wire being anchored in each of the formations A1 and A2.
  • their ends embedded in the formations can be provided with barbs.
  • the steel wires SD1 and SD2 are each provided with eyelets at their free ends.
  • the concrete spacer can still be provided with a slot in the fresh concrete state, as shown in FIG. 5. It is then sufficient to insert the steel wire or wires into the slot and to close the slot again by pressing on the end faces of the concrete spacer (arrows in Fig. 5).
