  • the frame thus freed is then dismantled, while the scaffolding screed, which is no longer supported on this page, is manually in its original, horizontal position is held.
  • the scaffold plank can be lowered on this side so that it can be used one end rests on the lower level.
  • the scaffold plank is then from the other support bar lifted off and completely disassembled.
  • the object is achieved by providing a head fitting solved a scaffold plank for a cone frame, which has connection holes that the Pick up the tenon of the tenon framework, the front of the head fitting is flattened at the top and bottom and the connection holes a cylindrical part have whose diameter is larger than that of the pin and the starting from this cylindrical part to the top and bottom of the Widen the head fitting.
  • the cylindrical part is preferably in the middle between the top and bottom the head fitting arranged.
  • the diameter of the is also preferably cylindrical part that 1.1 to 1.7, particularly preferably 1.3 to 1.5, very particularly preferably 1.35 to 1.45 times the diameter of the pin, the pin normally has a diameter between 10 -15 mm. All in one the cylindrical part has a particularly preferred embodiment Diameter between 20 and 22 mm.
  • the height of the cylindrical part is preferably between 0.5 and 10 mm, particularly preferably between 4 and 6 mm.
  • connection holes widen above and below the cylindrical part along any shape.
  • These extensions preferably have the shape of a cylinder, which adjusts to the Connect the cylindrical part and a larger diameter than this exhibit.
  • These extensions in the transverse direction of the screed are particularly preferred flattened so that the extensions viewed from above or below one have an elliptical cross-section.
  • these have extensions the shape of an elongated hole, the width of which corresponds to the diameter of the cylindrical part corresponds.
  • the center of the long axes falls Elongated holes preferably do not coincide with the central axis of the cylindrical part.
  • the center of the long axis is particularly preferred, based on the central axis of the cylindrical part, in the direction of the screed adjoining the head piece postponed.
  • the upper and the lower Extension can be designed differently, but are preferably identical.
  • these extensions are also preferably in the form of a blunt Cone, the pitch angle of the cone, based on the central axis is preferably between 20 and 31 °.
  • the slope angle of the extension up and down expansion may be different, but are preferably the same.
  • These conical extensions are particularly preferred flattened in the transverse direction of the screed, so that the extensions from above or below considered to have an elliptical cross section.
  • the extensions have the Shape of an elongated hole, the length of which increases with distance from the cylindrical part increases, while the width remains constant and the Corresponds to the diameter of the cylindrical part.
  • the Center of the long axes of the elongated holes preferably not with the center axis of the cylindrical part together.
  • the center of the long axis is particularly preferred, related to the central axis of the cylindrical part, in the direction of the Headpiece adjoining screed moved.
  • the upper and lower extensions can be designed differently but preferably identical.
  • connection holes are preferably in each case based on their longitudinal axis between 25 and 40 mm from the two lateral limits of the Head fitting attached.
  • the distance of the central axis of the cylindrical part of the vertical portion of the face is preferably in the longitudinal direction between 20 and 26 mm, particularly preferably between 22 and 24 mm.
  • the head fitting is flattened at the top and bottom, so that it is preferred has a vertical area in the middle, preferably 7 to 14 mm, is particularly preferably 10 to 12 mm wide. Starting from this vertical part, the head fitting flats up and down along any Curve continuously. The flattening preferably takes place along a straight line with a pitch angle of preferably 60 to 65 °.
  • the inventive preferably cast from aluminum or plastic or sprayed.
  • Polyamide is preferably used as the plastic.
  • Another object of the present invention is also a scaffold screed with the inventive head fitting on each of its two ends.
  • the invention also relates to the use of the invention Head fitting and the scaffold plank according to the invention as part of a Cone structure
  • connection hole has a cylindrical part 6, which has a diameter of 21 mm and a height of 5 mm.
  • the cylindrical part is followed by widenings 7 at the top and bottom, which in the present case have the shape of an elongated hole, which lengthens with increasing distance from the cylindrical part.
  • the width of the elongated hole is constant and corresponds to the diameter of the cylindrical part 8 and that the center of the long axis of the elongated hole is to the right of the central axis 9 of the cylindrical part. Accordingly, the flank 10 of this conical widening is steeper than the flank 11.
  • the flares above and below the cylindrical part are identical. It can also be seen that the extension protrudes into the upper and lower flats of the front end of the head piece.
  • the head piece On the face side, the head piece has a vertical section 12 which is in the middle of the Head piece is arranged and is 11 mm wide. Close this vertical area flats at the top and bottom at an angle of 27 ° with respect to the vertical range.
  • the headpiece is made of polyamide, 51 mm thick and has the width of the used screed.
  • the longitudinal axis of the connection holes is 30 mm from the Side margin arranged.
  • FIG. 1a also shows a part of the head fitting 1 according to the invention in a top view and as a corresponding section.
  • the widenings 7 ' also have the shape of an elongated hole, the length of which, however, does not change with increasing distance from the cylindrical part 6'. From the top view it can be seen that the width of the elongated hole is constant and corresponds to the diameter of the cylindrical part 8 'and that the center of the long axis of the elongated hole lies to the right of the central axis 9' of the cylindrical part.
  • Figure 2 shows the head fitting according to the invention installed in a cone frame.
  • the head fitting 17 according to the invention rests on the support bar 13 of the scaffold frame 16 and the pins 4 protrude into the connection holes.
  • the next scaffold frame 14 with a horizontal scaffold tube 15 is shown above the head fitting.
  • the scaffold tube 15 acts as a safety catch for the head fittings 17 and 18 and thus for the corresponding scaffold plank.
  • the head fitting according to the invention is shown in the so-called partial dismantling.
  • the scaffold plank 21 is seated on one side on the scaffold plank of the level below.
  • the pin 21 lies on the flanks of the extension of the connection holes. Due to the lower flattening of the face of the head fitting according to the invention, the face of this head fitting does not abut the face of the opposite head fitting.
  • the partial dismantling of peg stands equipped with the scaffolding planks according to the invention can also be explained on the basis of FIG .
  • the frame that stands to the right of the frame 19 and with it on one level (not shown) is dismantled.
  • the scaffold plank 21, which at this time is still on two support bars is raised and the frame, which is to the right of frame 20 and is on one level with it (not shown), is removed.
  • the free side of the scaffold plank 21 can then be placed on the level underneath and the scaffold plank 21 can then be lifted out of the pin 22 and transported away. Due to the shape of the end face of the head fitting, the vertical scaffold tube 23 of the frame 19 is not in the way.
  • the head fitting according to the invention has the advantage that the so-called partial dismantling of scaffolding is possible without compromising e.g. when securing against lifting have to be done. This means that the scaffold can be dismantled quickly possible. Due to the flattening of the end face of the invention Head fitting will also increase the risk of injury when handling the Scaffolding planks reduced.
