Definitions

  • the invention relates to a connecting piece for connecting two gutter ends according to the preamble of patent claim 1, a method for producing the connecting piece according to the preamble of patent claim 6 and a device for carrying out the method according to the preamble of patent claim 8.
  • a generic connector is described in FR-A 1 424 338.
  • the known connector is a plastic casting.
  • the gutter end areas are received in a groove of a double lip, which runs perpendicular to the longitudinal axis of the connecting piece.
  • the connecting piece has a double-T profile, in which the outer flanges are wider than the inner flanges formed by the double lip.
  • the known connecting piece had a sheet metal piece adapted to the semicircular gutter outer profile, which overlapped with one edge overlapping the gutter end and the other edge of which was formed into a bead which could be pushed onto the gutter bead of the gutter longitudinal edge on the side facing away from the house wall.
  • the connecting piece was plugged onto one end of the gutter and the other end of the gutter to be connected to the first end of the gutter was pushed into the bulge of the connecting piece and into the overlapping edge of the connecting piece.
  • the known connectors are complex to manufacture and bulky. Due to their large volume, they require a large transport space or complex and therefore expensive packaging and are also extremely vulnerable to bending or break easily and can be easily damaged.
  • the invention has for its object to provide a simple to produce connecting element, which due to its shape is stable and robust against bending and requires minimal space for shipping and requires minimal care.
  • FIG. 1 one end of a gutter 1 and 3 is shown connected to a connector 5 according to the invention, which is adapted to the curves of the gutters 1 and 3.
  • the semi-cylindrical gutters 1 and 3 merge along the sides, as can be seen in FIG. 2 on gutter 1, at one end into a circularly curved edge piece 7, the so-called gutter bead and at its other end into a so-called gutter trailing edge 8.
  • This gutter bead 7 gives the gutters 1 and 3 mechanical stability against deformation by z. B. branches of trees; this also increases their overall bending stiffness.
  • the gutter bead 7 is mounted on the roof side facing away from the house wall.
  • the connecting piece 5 has, as shown in cross section in Figure 3, a double-T profile, one of the two transverse flanges 9 through two flange halves 9a and 9b of a sheet metal strip 11 and the connecting web 13 and the other cross flange 15 double-walled through the inner part of the Sheet metal strip 11 are formed.
  • One end of a gutter 1 or 3 is in the space formed as a gap 17a or 17b by the two flanges 9 and 15.
  • the gap 17b is shown larger than in reality so that it is visible at all.
  • the flange halves 9a and 9b abutting the gutter bottom of the gutter ends are wider than the flange halves 15a and 15b abutting the gutter outside bottom.
  • the different widths of the flange halves 9a or 9b and 15a or 15b ensure that the connecting piece 5 is simply plugged onto the respective gutter end.
  • the two flange halves 9a and 9b abut each other so closely that the two web halves 13a and 13b also abut each other as a connection between the flange halves 9a and 15a or 9b and 15b.
  • a gutter end piece not shown, to a gutter end is carried out analogously to the connection of two gutter ends described above, but here the gutter end piece with the connecting piece 5 is firmly connected to the gutter end.
  • the wall of the gutter end piece stuck in the gap 17a or 17b is drilled by using the holes 21 in the connecting piece 5 as a drilling jig, and then through the holes threading screws or screws which are tightened with a nut.
  • FIGS. 4a to 4e and 5 and 6a to 6d and 5 Two examples of the bending process are shown in FIGS. 4a to 4e and 5 and 6a to 6d and 5 with their individual bending processes by means of which the connecting piece 5 is bent out of the sheet metal strip 11 to form the double-T-shaped profile.
  • the sheet metal strip 11 lies, as shown in FIG.
  • the surface of the pressure stamp 25 and the surfaces of the bending flaps 27a and 27b are flush with one another.
  • a second stamp 29 is located behind Pulled away directly above the pressure stamp 25, so that the sheet metal strip 11 can be easily placed on the pressure stamp 25 and the bending flaps 27a and 27b.
  • the width of the pressure stamp 29 is smaller by a tolerance than the width of the flange 15 to be produced, reduced by twice the sheet thickness of the metal strip 11.
  • the width of the pressure stamp 25 corresponds approximately to the width of the flange 15.
  • the pressure stamp 29 is lowered onto the surface of the metal strip 11.
  • the central region of the metal strip 11, which corresponds approximately to the width of the flange 15, is now clamped between the two pressure stamps 25 and 29.
  • the two bending flaps 27a and 27b are now folded against the side surfaces of the pressure stamp 29, as a result of which the sheet metal strip 11 is bent into a U-shaped channel 30 with two channel side walls 32a and 32b, as shown in FIG. 4c.
  • the bending flaps 27a and 27b are then folded back into their starting position, as a result of which the U-shaped channel 30 opens out slightly and the plunger 29 is then pulled back upwards by a distance d.
  • the distance d is, up to a tolerance, the sum of the height of the web 13 to be obtained after the entire bending process plus the (3rd, 2nd / 4th) times the width of the flange 15 to be obtained after the bending process, plus three times the sheet thickness of the sheet metal strip 11 .
  • a narrow pressure stamp 31a or 31b is used as the third and fourth at a height which, apart from a tolerance, is at a distance a from the surface of the pressure stamp 25, on both sides of the groove side walls 32a and 32b of the U-shaped curved groove 30 Pressure stamp horizontally pressed against the channel side walls 32a and 32b, whereby a crease line is formed. While the pressure stamps 31a and 31b are pressed against each other, the pressure stamps 25 and 29 are also pressed against each other.
  • the sections adjacent to the two fold lines are each Channel side wall 32a and 32b pressed towards each other, the gap 17a and 17b being kept free by the pressure stamps 31a and 31b between the two sections of each channel wall 32a and 32b adjoining the fold line.
  • the amount of the current printing speed of the printing stamps 29, 31a and 31b are the same and that of the printing stamp 25 is twice as large.
  • the distance a is, up to a tolerance, the sum of half the web height to be obtained after the bending process, plus twice the sheet thickness of the sheet metal strip 11 plus ( ⁇ 2 / 2) times the width of the flange 15 to be obtained after the bending process Stamp 31a and 31b is smaller than the height of the web 13 by a tolerance.
  • the connecting piece 5 now bent to form a double-T profile, is pushed in a further operation by a round bending device 33 shown in FIG. 5 with a drive roller 35a, a bending roller 35b and a counter roller 37 in the direction of arrow 39.
  • the connecting piece 5 is bent semicircular to its final shape and its flanges 9 and 15 are shaped flat and parallel to one another.
  • the double-T profile connecting piece 5 with the round bending device 33 can also be bent in a U-shape in order to use it as a connection piece, not shown, for U-shaped gutters, not shown.
  • the sheet metal strip 11 can also be deformed using a device as shown in FIGS. 6a to 6d.
  • the device shown in FIGS. 6a to 6d has a first one oblong pressure stamp 41.
  • the pressure stamp 41 On its underside, the pressure stamp 41 has a right-angled web 45 for forming a U-shaped grooves 43, as described below.
  • a second pressure stamp 47 designed as a die is formed with a rectangular depression 49 to match the pressure stamp 41.
  • the width of the depression 49 corresponds to the outer width of the U-shaped channel 43 to be bent and the width of the extension 41 is the width of the channel 43 minus twice the material thickness of the metal strip 11 minus a tolerance.
  • the depth of the depression 49 and the height of the web 45 are the same as the flange width 15a or 15b of the connecting piece 5, except for a tolerance caused by the bending process described below.
  • a U-shaped channel 43 is first produced, which, in contrast to the U-shaped channel 30, approximates the flat channel bottom 54 has parallel gutter edge regions 55a and 55b which are kinked by a kink line.
  • the metal strip 11 is placed centrally in the longitudinal direction over the depression 49 of the pressure stamp 47 and then from the web 45 of the pressure stamp 41 into the depression 49 and from its edge regions 51a and 51b, which run approximately parallel to the bottom surface of the web, against the approximately parallel to the bottom surface of the depression 49 extending side surfaces 53a and 53b of the pressure stamp 47 pressed.
  • the pressure stamp 41 is moved away from the pressure stamp. As shown in FIG. 6b, a U-shaped channel 43 with channel edge regions 55a and 55b running approximately parallel to the channel bottom 54 (see FIG. 6c) has been formed. Depending on the material and wall thickness used, the channel 43 can be removed from the depression 49 or must be ejected with an ejector (not shown).
  • the U-shaped channel 43 is inserted into a further pressure stamp arrangement, as shown in FIGS. 6c and 6d.
  • This pressure stamp arrangement has analogous to the device shown in Figures 4a to 4e, also a third and fourth narrow pressure stamps 57a and 57b.
  • the two narrow pressure stamps 57a and 57b can be moved relative to one another perpendicular to the direction of movement of the pressure stamp 59b and are arranged at a distance from the sheet thickness of the sheet metal strip 11 plus a tolerance below the pressure surfaces of the pressure stamp 59a.
  • the U-shaped groove 43 is placed with its groove outer bottom on the pressure surfaces of the pressure stamp 59b and held in position by the partially retracted pressure stamps 57a and 57b, which engage under the groove edge areas 55a and 55b.
  • the pressure ram 63 is constructed symmetrically and has a displaceable partial ram 67 in the center of its cross section, the flat pressure surface 69 of which projects beyond the remaining, laterally lying, flat pressure surfaces 71a and 71b by the depth of the U-shaped channel 43 to be formed.
  • the pressure stamp 65 has a depression 75 formed by two temporally displaceable partial pressure stamps 73a and 73b.
  • the narrow pressure stamps 57a and 57b are arranged laterally next to the pressure stamp 63, as already described above.
  • the U-shaped channel 43 is formed with the stamp arrangement shown in FIG. 7a.
  • the narrow pressure stamps 57a and 57b then engage under the channel edge regions 55a and 55b of the U-shaped channel 43, the groove 43 is thereby held in its position, the two lateral partial pressure stamps 73a and 73b are pushed outward and the partial pressure stamp 67 is pulled back so far that the entire printing surface of the printing stamp 63 forms a flat surface.
  • the pressure stamps 57a and 57b are moved towards each other and the free printing surfaces of the pressure stamp 65 are moved towards the pressure stamp 63, whereby the double-T-shaped profile is formed.
  • the connector 5 according to the invention is simple to manufacture and requires a small transport space; it can even be transported without packaging without being bent due to its compact and stable design.
