Definitions

  • This object is achieved in such a way that at least one profile element consisting of expanded metal and having holes for the passage of reinforcing bars is used as lost formwork for two stages of a building to be concreted.
  • profile elements can be placed on and next to each other and supported on the one hand by proppants before the first stage is concreted.
  • the profile element 1 shown in the figures which is used as lost formwork for two stages to be concreted of a building, not shown, consists of expanded metal; But it can also, for example, from a marked, stamped, printed or ribbed steel sheet, which makes the surface of the sheet rough. The evenly roughened surface gives an optimal connection between two concrete castings of a building.
  • the profile element 1 is double U-shaped in cross section with a web.
  • the cross section of the profile element 1 can also be U-shaped (see FIG. 4) or trapezoidal, meandering or undulating or have a combination of these shapes.
  • Holes 2 are punched through the profile element 1 in the vicinity of its outer longitudinal edges, each forming a row of holes running parallel to the longitudinal edge of the profile element. These holes 2 are intended for reinforcing bars 5, which are carried out by them and concreted in in the two stages of the structure. The distance of the holes 2 from the outer longitudinal edges of the profile element 1 is determined by the structural engineer depending on the type of building. A reinforcing bar 5 is used per hole 2.
  • the profile element 1 is supported on the one hand by several wooden wedges 3 before concreting the first concreting stage of the building (see the figures). Instead of wooden wedges, steel angles can also be used.
  • a plurality of profile elements 1 can be placed one on top of the other and next to one another without mutual connection, wherein they are only held on the wooden wedges 3 by means of fastening means 4.
  • the profile elements 1 .. are placed loosely on wooden inserts 7 which extend over the entire length of the profile elements 1 on the formwork 8. Instead of wood, another material, such as plastic, can also be used.
  • the wooden wedges 3 and wooden inserts 7 are removed from the profile element or elements 1 and can be used further. After the concrete of the first concreting stage 6 has hardened and the wooden wedges 3 have been removed, the second one Concrete stage of the building.
  • the thickness of the fine-mesh expanded metal from which the profile element 1 is made is advantageously 0.7 to 1.5 mm.
  • the profile element or the profile elements 1 remains or remain attached to its end face after the concrete of the first stage 6 has hardened, this end face is profiled accordingly. This ensures perfect interlocking of the second concreting stage with the first concreting stage.
  • the assembly of the profile element which is lighter than e.g. Having wooden panels is much lighter than with conventional wooden formwork.
  • the finished profile elements are e.g. delivered from the workshop in lengths of 250 cm; they do not need to be cut on site. Since the holes 2 are already pre-punched in the desired division in each profile element 1, they do not have to be laboriously manufactured on the construction site.
  • the profile element or the profile elements is not removed; thus a lost formwork is formed, so that the formwork work is eliminated and the end face of the first concreting step does not have to be roughened.
  • the height and length of the individual profile elements can be combined as required.
  • the interlocking of the two concreting stages is achieved without additional work. A compact surface of the concreting stages without air bubbles is achieved.
