Definitions

  • the invention relates to a formwork panel for producing a formwork with an open bottom, of the type explained in the preamble of claim 1.
  • Such a formwork panel is known from DE-PS 36 01 882.
  • the known formwork panel consists of a strip of a latticework made of steel bars shrunk with plastic film.
  • a separate formwork plate must be used for each of the side walls of the formwork.
  • the formwork panels are angled L-shaped during manufacture or shortly before use, so that a footprint is created for setting up the formwork wall on the ground. Nevertheless, the known formwork walls still have to be connected to the subsurface and / or to one another in order to ensure the necessary stability of the formwork.
  • the plastic film is not dimensionally stable, although it shrinks the latticework much more tightly than would be possible with a plastic film that was only attached and welded on.
  • the invention is therefore based on the object of creating a formwork panel for formwork which can be easily and inexpensively produced and erected.
  • the desired formwork can be produced in a simple manner and without additional fastening and tensioning work by simply bending up the side walls.
  • Loose cross bars can be used in the production, which are held by the side walls made of dimensionally stable material at a predetermined distance and in the predetermined position from one another.
  • waffle and flake sheet described in claim 2 as a dimensionally stable material. So far, these sheets have been used, for example, to produce non-slip steps in the industrial sector. These sheets have an embossed surface which shows recesses on one sheet side and elevations on the other sheet side. In the case of scale plates, the embossments also contain through openings (such as a grater), but they are not so large that concrete can pass through in noticeable amounts. By using these embossed sheets, a controlled roughness is achieved on the side surfaces of the cast concrete part, which is a good adhesive bridge for casting additional concrete parts.
  • the longitudinal bars are preferably according to claim 6 at particularly stressed locations, for. B. arranged on a bend, or it is used according to claim 7, from the outset a metal grid.
  • the formwork according to the invention is produced by applying the strips of the dimensionally stable material either directly (claim 8) or together with additional longitudinal bars (claim 9) to parallel flat or already pre-bent cross bars at the points later corresponding to the side walls.
  • FIG. 1 shows a formwork panel 1 according to the invention, which has a plurality of parallel transverse bars 2 made of structural steel. Length, diameter and distance of the cross bars 2 are according to the dimensions and Requirements of the desired formwork selected.
  • the respectively aligned, free ends of the cross bars 2 are connected on both sides to each other with a strip 3 of a dimensionally stable waffle plate, the areas of the cross bars 2 lying between the strips 3 remaining uncovered.
  • the width and length of the strips 3 correspond approximately to the dimensions of the side walls of the desired formwork part.
  • Fig. 2 shows a further embodiment of a formwork panel 1 ', which has already been bent into a U-shaped formwork part, such as are used for example for a beam or strip foundation.
  • the formwork panel 1 ' was bent in such a way that the strips 3' are located in the area of the side walls, while the uncovered area of the cross bars 2 'stands as the floor on a surface. If necessary, the end faces can be closed using conventional formwork.
  • the strips 3 'consist as also shown in FIG. 3, of a scale plate which has been welded to the inwardly facing sides of the cross bars 2'.
  • the strips 3 'made of scale plate extend from the free ends of the cross bars 2' into the region of the bend.
  • Longitudinal bars 4 are welded to the outside of the cross bars 2 '.
  • two longitudinal bars are provided per side wall, namely one of the longitudinal bars 4 connects the transverse bars 2 'in the area of their free ends and the other of the longitudinal bars 4 connects the area near the bend.
  • the strips 3 'of scale sheet are welded to the cross bars 2' at 5 and arranged in such a way that the scales 6 emerging from the plane of the strip 3 'are directed into the interior of the formwork.
  • FIG. 4 shows a further possible use of the formwork panel according to the invention for a formwork which is closed in the circumferential direction, for which both the formwork panel 1 (as shown) and the formwork panel 1 'can be used.
  • this formwork two formwork panels 1 which are adapted to one another in terms of their dimensions are bent to form a U-shaped formwork part and are offset from one another by 90 o , so that one strip 3 of the first formwork panel 1 covers the uncovered area of the cross bars 2 of the other formwork panel 1.
  • the formwork panels 1 are appropriately bent such that each of the edges of the strip 3 lying against the uncovered areas of the cross bars 2 is angled slightly, so that the strips 3 overlap one another in the corners when the curved formwork panels 1 are placed one inside the other, so that there no concrete can escape.
  • Fig. 5 shows a further formwork panel 10, the cross bars 12 together with longitudinal bars 14 form a regular metal grid.
  • the strips 13 correspond to the strips of the previous exemplary embodiments and are connected directly to the cross bars 12 of the metal grid.
  • the circuit board 10 was bent in such a way that the longitudinal bars 14 point outwards.
  • a conventional structural steel mat can also be used as the metal grid.
  • the formwork panel or the formwork part is preferably produced automatically, the desired number of crossbars being fed in parallel alignment to a welding device in which the strips of dimensionally stable material are welded, dotted or otherwise applied. After or before applying the strips, the cross bars are cut to the desired length. The cross bars are then bent, possibly together with the lower edge of the strips, so that a U-shaped formwork part is created. If necessary, however, the bending can take place before the strips are applied.
  • the longitudinal bars can be welded onto the cross bars before or after the strips. When using a metal grid, this is first prefabricated and only then connected to the strips.
  • the strips are preferably welded directly onto the cross bars. However, it is also possible to weld the strips to the longitudinal bars so that they are connected to the transverse bars via the longitudinal bars.
  • the strip in the exemplary embodiment according to FIGS. 2 or 5 can also be angled in the manner shown in FIG. 4.
  • an expanded metal in particular a commercially available, fine-mesh expanded metal mesh, or any other suitable, dimensionally stable material can also be used for the strips.
  • the number of transverse or longitudinal bars can be increased or decreased compared to the graphic representation. If thinner cross bars are used, this can Formwork part may also be bent directly on site.
