Definitions

  • the present invention relates to a formwork panel for producing concrete bodies with one or more panels on which at least one metal foil or at least one metal sheet is glued on at least one of its surfaces.
  • the object of the invention is therefore to improve a generic panel to the effect that the disadvantages mentioned are avoided.
  • the plate (s) light metal preferably aluminum or an aluminum alloy, has (have) or consists of (consist).
  • a basic idea of the invention is therefore to use one or more plates of light metal instead of wooden plates for supporting the metal foil forming the shell surface or the metal sheet forming the shell surface.
  • Light metals are understood to mean all metals and their alloys which have a density of less than 4.5 g / cm 3 (under normal conditions).
  • Preferably, light metals or their alloys are used which have a density of not more than 3.0 g / cm 3 (under normal conditions).
  • this plate (s) comprise aluminum or aluminum alloy or consists entirely of such a material. The use of light metal plates swelling and thus warping the panel is completely avoided even during prolonged use.
  • the plates are in the sense of weight minimization as a hollow body, optionally formed with corresponding reinforcing struts. As a result, a high stability and low weight of the panel can be achieved particularly easily. Due to the dimensional stability of the thus provided plate (s), the bonding with the metal foil or the metal sheet is maintained over time, so that no separation phenomena are to be feared over time.
  • the metal foil or the metal sheet on its (its) entire surface is supported by the or the plate (s).
  • the plate (s) is a closed surface, ie has no open holes.
  • the metal foil or sheet metal As a metal foil or sheet metal, a material is advantageously used, from which concrete residues can be easily detached, without resulting in a deformation or otherwise affecting the surface of the metal foil or the metal sheet.
  • the metal foil or the metal sheet comprises, or consists of, at least on its surface, preferably completely, steel or in particular stainless steel.
  • the thickness of the metal foil or the metal sheet is favorably in the range between 0.5 and 2 mm, more preferably between 1 and 1.5 mm.
  • Inventive formwork panels are preferably used in slipforms. But they can just as well be used for other or stationary formwork. In this sense, a formwork, in particular slip form, for the production of concrete bodies with at least one formwork panel according to the invention is also an object of the present invention.
  • Fig. 1 a perspective view is shown, which essentially shows a view of the concrete in the operation facing side 8 of the formwork panel 1, which is formed by the operationally facing the concrete surface 9 of the metal foil or the metal sheet 3.
  • This page is also often referred to as a scarf surface.
  • This surface is formed in the illustrated embodiment of a metal sheet 3 made of stainless steel, which is glued to the only visible here at the edge of plates 2.
  • the plates 2 made of aluminum hollow bodies. Even if no further explicit reference is made in the following, it is of course also possible for a metal foil to be glued to the plates 2 instead of the metal sheet 3.
  • the plates 2 themselves need not necessarily be made of aluminum or an aluminum alloy, but may also have another light metal or be made entirely of it. In addition, it is also not absolutely necessary for the plates to be a hollow body, even if hollow bodies generally represent a preferred embodiment of the plates 2.
  • end strips 6 and 6 ' are arranged on the opposite end faces of the plates. Again, this is conveniently hollow profiled strips, which may also be made of metal or light metal, and particularly preferably made of aluminum or an aluminum alloy. It is preferably provided that the end strip (s) 6, 6 'and the plate (s) 2, preferably by means of at least one comb strip 11, positively engage with each other.
  • Fig. 2 shows the rear view of the working position facing away from the concrete surface 12 of the formwork panel 1 gem.
  • Fig. 1 Here it is particularly easy to see that the respective adjacent plates 2 adjoin one another butt to butt, so that there are no intermediate spaces between them and the metal sheet 3 is thus supported over its entire area. It is advantageous if the, preferably all, adjacent plates 2 are connected to each other by means of tongue-and-groove connections 10 (also known under tongue-and-groove connection). Such types of connections are well known and not shown in detail here.
  • the plates 2 at a right angle to the end strips 6 and 6 'are adjacent are adjacent. Again, this is a preferred embodiment, but not mandatory.
  • the holes 20 are provided in the plates 2, which, as described in more detail below with reference to Fig. 6 to 11 explained, serve for attachment of support beams 15 to the panel 1 and the plates 2.
  • Both sides thus have smooth surfaces, which is favorable for a particularly simple and space-saving stacking of the formwork panels.
  • the absence of projections also ensures that the formwork panels are not damaged when stacked or removed from each other.
  • Fig. 3 now shows a formwork panel 1, before the metal sheet 3 is adhered to the surface 4 of the plates 2.
  • two depressions 5 for receiving adhesive or adhesive tapes are arranged in said surface 4 of the plates.
  • the recesses 5 for receiving adhesive or adhesive tape preferably evenly or at least partially in one direction equidistant, over the entire surface 4 of the plate (s) 2, on the Metal foil or the metal sheet 3 is glued, are arranged distributed. It is important, above all, a reasonably uniform distribution of these recesses 5, so that the metal sheet 3 over its entire surface evenly with good the plates can be glued. Of course, it is particularly favorable if, in particular, corresponding recesses 5 are provided on the edges of the gear blade 2.
  • the end strips 6 and 6 'shown in this embodiment also have at least one recess 7 in which the lower and the upper end of the metal sheet 3 are arranged or can be glued.
  • Fig. 4 can be seen through the formwork panel 1, the recesses 7 are in the end strips 6 and 6 'completely on the concrete facing side 8 of the formwork panel 1. This avoids that the metal sheet 3 to the outer edge 14 or the opposite outer edge 14' to the end faces of the panel has to be bent, which avoids the associated with a bending effort in the production. How very good in Fig.
  • the recesses 7 are arranged in the end strips 6 and 6 'and the panel 1 that in the operating position the concrete facing surface 9 of the metal sheet 3 is flush with the surface of the end bar 6 and 6' and the panel 1 , By this measure, attack surfaces on which the metal sheet 3 could be bent or demolished, avoided.
  • Fig. 4 is also the connection of the end strips 6 and 6 'with the plates 2 by means of the screws 21 to see well.
  • a preferred variant thus provides that the end strip (s) 6,6 'and the plate (s) 2 are screwed together.
  • the end strips 6 and 6 'and the plate (s) 2 engage one another in a positive, frictional or non-positive manner.
  • the comb strips 11 can be pressed under deformation of the material of the plates 2 in this.
  • the reverse arrangement is possible by the comb strips 11 or other shaped pins attached to the plates 2 or integrally formed and when joining in the end strips 6 or 6 'penetrate.
  • the panel 1 and the upper end bar 6 is chamfered at its outer edge 13.
  • the formwork panel 1 or the end strip 6 tapers in this area in the direction of the outer edge 14 of the formwork panel 1. This is favorable in order to be able to insert fixtures between the formwork panels from above during concreting.
  • Such built-in parts can, for. B. anchor plates or placeholder for recesses in the concrete.
  • a V-shaped upper insertion opening which opens upwards in the operating position, into which these parts can be inserted without jamming or catching, is created by the bevelled outer edges 13.
  • the flush termination of the metal sheet 3 and / or the bevelled outer edge 13 can of course also be realized in formwork panels 1 without end strips 6, 6 '.
  • Fig. 5 shows a plan view of a plate 2 with removed end strip 6 in the region of the outer lateral edge of the formwork panel 1. To see is the hole 22 into which the connecting screw 21 can be screwed. In addition, the peripheral recess 5 can be seen in the surface 4 of the plate 2, which is provided for receiving adhesive or adhesive tape. It can also be seen well that the metal sheet 3 also terminates at its lateral boundary in the recess 5 and is flush with the lateral outer edge 30 of the plate 2 and thus the shuttering panel 1.
  • Fig. 6 now shows a view of the rear surface 12 of the panel 1, wherein two support beams 15 are fixed to the plates 2.
  • fastening connecting elements 16 are provided which engage on the one hand in the holes 20 of the plates 2 and on the other hand are fastened via at least one respective fastening means 18 to the support beam 15.
  • the fastening means 18 consist of holes through which the base leg 17 of the connecting element 16 can be screwed by means of the screw 21 to the supporting beam 15.
  • any other, known in the prior art and suitable for this purpose fastener 18 can be used.
  • the connecting element 16 has at least one base leg 17 with the fastening device 18 and at least one hooking leg 19 angled relative to the base leg 17, preferably orthogonally.
  • the Einhakschenkel 19 is used to engage in the respective hole 20 in the plates. 2
  • Fig. 7 shows a detailed view, in which the connecting element 16 is arranged in its end position.
  • Fig. 8 shows an intermediate position when hooking the Einhakschenkels 19 in the hole 20th
  • Fig. 9 to 11 show sectional views, with reference to which the fastening operation is shown in detail.
  • Fig. 9 shows how the Einhakschenkel 19 is inserted into the hole 20.
  • the base leg 17 is then brought into contact with the upper side of the supporting beam 15.
  • the end position achieved in this case is in Fig. 10 shown.
  • the footprint 23 realized in this exemplary embodiment which in its cross section fills almost the entire opening width of the hole 20.
  • the support beam 15 is securely attached to the (the) plate (s) 2 and thus attached to the panel 1.
  • Fig. 12 shows by way of example a schematic representation of a possible embodiment of a sliding formwork, which may have such formwork panels 1.
  • the slip formwork has a yoke 29, which is supported by vertical bars or climbing poles 25 and is driven during the concreting of the concrete body 26 along the bars 25 step by step in each case after sufficient curing of the just-concreted section.
  • working platforms 27 and 28 are attached.
  • the yoke 29 engages over the respective upper end of the concrete body 26 in a U-shape.
  • On both sides of the concrete body 26 downwardly projecting arms of the yoke 29 are provided, on which the support beams 15 are fixed, to which in turn in the manner described the formwork panels 1 are mounted by means of the connecting elements 16.
  • formwork panels 1 according to the invention can be used not only for slipforms but also for any other type of formwork.
