Definitions

  • the best known way to connect metal sheets is the flange connection.
  • the ends of the sheets are strongly angled so that a flange results, and screwed to this flange with screws.
  • An elastic sealing strip is inserted between the flanges for a dust-tight seal.
  • a prerequisite for a dust-tight connection is sufficient sheet thickness and small screw spacings.
  • a liquid-tight seal is generally only achieved if flanges with a much greater wall thickness than those of the sheet are welded to the sheet ends and or if the angled sheets are additionally reinforced in another way.
  • connection of metal sheets is described, inter alia, in the published patent application DE 32 45 485.
  • the connection is first made and then the seal is applied by applying a sealant.
  • This type of design may meet the reduced requirements for animal feed; critical for food. In any case, it is not suitable for other purposes.
  • the differences from the aforementioned publication are discussed in detail.
  • the seal reduces the coefficient of friction between the metal parts greatly, and on the other hand, because the seal creates a second gap, which significantly enhances the function of the first-mentioned gap. Recognizing this fact, the sealing was retrofitted to the aforementioned OS. The latter is very disadvantageous in many cases, on the one hand, due to the gradual rubbing off of the sealant by the bulk material, and on the other hand, if the sealant must not come into contact with the bulk material for other reasons.
  • Fig. 1 shows a connection according to the invention in the simplest and most effective form.
  • this connection is subjected to tensile stress, the metal sheet end 8 is pulled against the leg 3 of the outer terminal strip 6 and held by it. If the internal terminal strip 5 and the outer terminal strip 6 is sufficiently rigid, then this compound can preferably solve at 180 o bending only by tearing the sheet.
  • the connection thus has a strength that is close to the tensile strength of the metal sheet. If the terminal strips give way by a very small amount, then the folded part of the metal sheet bulges slightly towards the outer terminal strip. As a result, the seal is additionally pressed against the external terminal strip and, if at all possible, is even more effective. If the tensile force continues to increase in such cases, the metal sheet will tear as described above.
  • a disadvantage of this connection is the somewhat difficult assembly.
  • Fig. 2 shows a connection in which the assembly is facilitated by the double fold of the sheet.
  • the second 180 o fold can also be provided clockwise.
  • Fig. 3 shows an embodiment in which the assembly is much easier.
  • the inner terminal block consists of a special profile and protrudes into the interior of the container, etc., which could be particularly annoying when pipes are connected axially.
  • Fig. 4 shows a further variation with a view to easier assembly.
  • the sheet of metal had to be folded three times here.
  • the gap (12) between the inner terminal strip and the sheet metal plate is intended to accommodate a further seal. So that the seal does not come into contact with the stored goods and is also held firmly, a cover strip 13 is provided, which can also be made of this material, in particular if the metal sheet is made of a high-quality material, while the terminal strips are made of an inexpensive, possibly stronger material.
  • Fig. 5 shows a variation of FIG. 4.
  • the 180 o fold has been omitted for reasons of cost.
  • the folds would bend under tensile stress on this connection.
  • the sheet end can then slip out of the clamping between the inner clamping strip and the outer clamping strip at a fraction of the tensile strength of the sheet.
  • the seal 4 in FIG. 5 the coefficient of friction is increased significantly.
  • the actual tensile strength of this type of connection when used with a gap 12 is only partially used.
  • Fig. 6, 7 and 8 show variations to Fig. 4, with other sealing systems, but with the same behavior in tensile stress.
  • Fig. 9, 10, 11, 13 and 14 show variations to Fig. 5, with a different design of the seal. Here, too, an impairment of the friction caused by the seal should be reduced or eliminated.
  • Fig. 6, 7, 8, 13 and 14 show variations to Fig. 4 in relation to covering the seal by a cover strip (13).
  • 7, 8, 14 and 20 are particularly well suited for the axial connection of rounded metal sheets to tubes.
  • FIG. 15 shows a variation to FIG. 5 with the task of maximizing the strength of a connection.
  • the optimum strength in this system is only achieved if the leg length of the sheet, which in turn depends on the leg length of the outer clamping strip, is also sufficiently large.
  • a leg length in the embodiment according to FIG. 4 of about 3 to 5 times the sheet thickness is sufficient.
  • the leg length is extended to approximately 8 to 10 times the sheet thickness, as shown in FIG. 15, this results in a substantially higher resistance against bending of the bend even if a seal (4) is installed. Slipping out of the sheet is made very difficult or made impossible.
  • Fig. 16 shows the connection of 4 metal sheets to a round container.
  • Fig. 17 shows the connection of 4 metal sheets to a square container. If, for example, a connection according to FIG. 5 is provided here, the first 90 o fold is reduced to 45 o .
  • Fig. 18 shows 2 containers in quadrangular construction, connected to each other, but divided by an intermediate wall (22). If the width of the container is large, the required width of the sheet is produced by a connection (20).
  • connection is not only loaded on tension, but also additionally on bending, see arrow 23, a connection according to FIG. 15 is best suited here. It has a multiple bending resistance compared to a flange connection.
