Definitions

  • the invention relates to a method for producing a formwork part with an open bottom of the type explained in the preamble of claim 1.
  • Such a method is known from CH-A-459 518.
  • strips of a non-commercially available, separately produced sheet metal material are used, into which beads, tabs and openings are formed in such a way that fastening rods are inserted and the strips can be bent at predetermined locations.
  • the assembly to formwork with an open floor takes place directly on the construction site, with U-shaped cross bars first having to be set up at predetermined intervals and held in place until the strips of the sheet metal material have been pushed on.
  • the known method is costly and labor-intensive due to the need to use a strip material to be produced separately and due to the cumbersome handling on the construction site.
  • a firm connection between the strips and the bars is not provided, so that the strips have to be additionally fastened to one another and to the bars in order to ensure the dimensional stability of the formwork part.
  • 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.
  • 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 providing an inexpensive method for producing a formwork which is simple and inexpensive to erect.
  • the desired formwork part can be produced in a simple manner and without additional fastening and tensioning work by simply bending up the side walls.
  • the formwork panel used to manufacture the formwork part can be produced automatically. If necessary, the formwork panel can be transported flat to save space and only be bent to the desired formwork part in a few simple steps on the construction site.
  • waffle and flake sheet described in claim 2 as a dimensionally stable material.
  • These sheets were previously used, for example, to manufacture 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.
  • the embossments also contain through openings (such as a grater), but they are not so large that concrete can pass through in noticeable amounts.
  • 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 strips can either be connected directly to the cross bars, or applied to the longitudinal bars, which in turn are firmly connected to the cross bars.
  • the longitudinal bars are preferably at particularly stressed locations, for example at a bend, arranged, or it is used according to claim 8, from the outset a metal grid.
  • cross bars are bent in areas outside the strips.
  • edge areas of the strips can be bent together with the cross bars in such a way that edge areas of two parts of the formwork overlap when assembled to form a closed formwork, so that there is less of a risk of concrete escaping at these points.
  • 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 subsurface. If necessary, the end faces can be closed using conventional formwork.
  • the strips 3 ' consist 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 °, 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. Then the crossbars are bent, possibly together with the lower edge of the strips, so that a U-shaped formwork part is created.
  • 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.
