Definitions

  • the present invention relates to a strip-shaped concrete spacer with a support bar and two support bars molded onto it to form a U-shaped cross section.
  • Concrete spacers are required for concreting as spacing elements between reinforcing steel and formwork to ensure a uniform and defined concrete covering of the reinforcing steel.
  • a concrete spacer of the type mentioned is already known and is widely used.
  • the support bar of the known concrete spacer is provided with elongated recesses. Its support strips have a notched edge.
  • the known ßeton spacer is usually used so that it stands with its support strips on the formwork or bears against it and the reinforcing steel comes to rest on its support bar. By turning around, the known concrete spacer is also for installation suitable on soft insulation boards.
  • the concrete spacer according to the invention is accordingly characterized in that at least one approximately 2 to 4 mm high longitudinal rib is formed on the support strip on its side opposite the supporting parts and that this longitudinal rib is provided with transverse grooves at regular intervals.
  • the reinforcing irons can be inserted into the transverse grooves in the longitudinal rib or ribs and in this experience a fairly good stabilization against lateral slipping when laying.
  • the elaborate measuring of the distances as well as the elaborate alignment of the reinforcing bars on the construction site are not necessary.
  • the small height of the longitudinal rib (s) of only 2 to 4 mm and the resulting correspondingly small depth of the transverse grooves ensure that distances other than those specified by the sequence of the transverse grooves can also be selected.
  • the low height of the longitudinal ribs ensures that the concrete spacer can still be placed on soft insulation panels without unduly deforming them.
  • a strip-shaped concrete spacer according to the present invention or the short section shown by it is designated by 1. It has a support strip 2, on which two mutually parallel support strips 3 and 4 are formed to form a U-shaped cross section.
  • the support bar 2 is provided with elongated oval recesses, which are designated 5, 6 and 7.
  • the lower edge of the support strips has approximately semicircular notches at regular intervals, of which only one is designated by 8.
  • the support strip of the spacer shown On its side opposite the two support strips, on which reinforcing bars 9-12 rest, the support strip of the spacer shown is provided with two longitudinal ribs 14 and 15, respectively. While the entire height of the spacer above the formwork 16 is a few centimeters (typically between 1.5 and 4 cm), the two longitudinal ribs are each only a few millimeters, preferably only between 2 and 4 mm, high.
  • the two longitudinal ribs 14 and 15 are provided at regular intervals of preferably about 5 cm with transverse grooves, of which only two, designated 17 and 18 respectively, can be seen in FIG. 1.
  • the transverse grooves 17 and 18 mentioned are of the same length, i.e. arranged adjacent to one another in the same cross-section of the spacer, but on the other hand can also be arranged offset with respect to one another.
  • the depth of the transverse grooves preferably corresponds approximately to the height of the longitudinal ribs.
  • the reinforcing bars 9 and 10 are inserted into other such transverse grooves to prevent them from slipping sideways, which is why the corresponding transverse grooves are covered.
  • any other spacing than that specified by the sequence of the transverse grooves can be selected.
  • Regularly arranged transverse grooves of a more pronounced design which do not allow an alternative choice of the spacing of the reinforcing bars, would inevitably lead to structural errors in cases in which the spacing of the reinforcing bars corresponding to the spacing of the transverse bars is not prescribed by the engineering specifications.
  • the longitudinal ribs 14 and 15 are between the transverse grooves with a plurality of notches of less depth, for example in the manner of a Rack, provided, as is clear from Fig. 1.
  • Attaching the binding wire to the spacer is made considerably easier by shaping the recesses in the support strip in such a way that at least one, preferably dovetail-shaped nose projects into each of them.
  • a nose is shown in the recess 6 in Fig. 1 and designated 19.
  • the lugs protruding into the recesses are preferably each arranged with the transverse grooves in the longitudinal ribs in a cross-sectional plane of the spacer.
  • a plastic is particularly suitable as the material for the concrete spacer. If a plastic material is used, the concrete spacer can be produced in a manner known per se by extrusion, the longitudinal ribs 14 and 15 being obtained by suitable shaping of the extrusion nozzle without an additional operation. After the strand has been extruded, the recesses in the support strip and the semicircular notches in the support strips are made by punching out. The transverse grooves and notches in the longitudinal ribs can simply be pressed into the still soft strand.
  • Fig. 2 shows another embodiment of a strip-shaped concrete spacer according to the invention in profile.
  • This spacer again has a support strip 20 and two support strips 21 and 22 molded onto it to form a U-shaped cross section.
  • a single longitudinal rib 23 is formed on the support strip here.
  • the longitudinal rib 23 is formed directly next to the area 24 opposite the support strip 22 on the support strip 20 and thus laterally outside of the center thereof.
  • the support bar is again provided with recesses 25.
  • the recesses 25 are approximately C-shaped. They extend with their two legs over the entire width of the support strip 20 between the two support strips. The legs mentioned therefore also overlap with the longitudinal rib 23, as a result of which the transverse grooves 26 arise in the latter.
  • the recesses 25 are dimensioned, shaped and arranged in such a way that longitudinal rib sections and transverse grooves each have the same length Alternate sections.
  • the lower edge of the support strips 21, 22 again has approximately semicircular notches at regular intervals, of which only one is designated by 27. The notches are each arranged below the recesses 25.
  • the strip-shaped concrete spacer according to FIGS. 2 to 4 has the following advantages in particular: Because it has only one longitudinal rib provided with transverse grooves, the reinforcing bars can also be inclined. i.e. be laid on it at an angle other than 90 ° with respect to its longitudinal direction. Due to its simple profile, it can be easily extruded, with the longitudinal rib 23 being molded on at the same time. After extrusion, it is only necessary to punch out the recesses from the support bar and the notches from the support bars. When punching out the recesses from the support strip in the form described, the desired transverse grooves in the longitudinal rib are produced automatically, as a result of which no additional work step is required for their formation.
