Definitions

  • the invention relates to a scaffold coupling, according to the preamble of claim 1.
  • Scaffolding couplings are used to connect scaffolding tubes together or to attach to plug-in frames. It is essential that the Scaffolding coupling is safe to use, quick to lock and is to be solved, but the pipe to be enclosed is still secure holds. Since scaffolds regularly also have diagonal braces, scaffold couplings must also be able to each other Store sloping pipes safely. This is it known, two scaffold couplings on a riveted peg to work together to achieve the desired swivel lock to ensure.
  • the scaffold couplings Build top shells and bottom shells, with the top shell Swiveling on the lower shell via a joint on one side is stored, and on the opposite side Clamping element, for example in the form of a hammer head screw to provide the upper shell in the manner of a one-armed lever and the lower shell pulls together and thus their inner surfaces presses on the pipe to be covered.
  • a hammer head screw offers a fairly good load capacity.
  • Such scaffold couplings are mostly made of sheet metal today manufactured, due to the forces to be transmitted considerable Wall thicknesses are required. You usually try that required wall thicknesses by a suitable shape of the To keep sheet metal low. Most of the time, the shaped sheets are to be covered Tube bent into a U shape so that the half-shells each just rest against the end of the pipes to be covered.
  • the invention is based on the object to provide scaffolding coupling according to the preamble of claim 1, the gentle and safe the scaffolding parts to be connected stores together, the manufacturing costs cheap and the Service life should be high.
  • both the top and the lower shell made of extruded profile can also be opened initially ensure a large-scale plant on the pipe to be covered.
  • the pressure to be applied is low, so that there is no tendency to notches.
  • the scaffold coupling according to the invention is corrosion-resistant and durable use, which also improves dimensional accuracy, because it is prevented, for example, by corrosion scaffolding coupling made of sheet steel no longer the required Dimensional accuracy exists, with a reduced one Stability would exist.
  • an adapter according to the invention By implementing an adapter according to the invention on the Bottom shell can also avoid welded connections, so that the lower shell can remain exactly semicircular.
  • adapters allow a wide variety of mounting positions To take into account.
  • a vortex can be realized by a bolt, the two mutually opposing scaffold couplings.
  • the bolt can be parallel extend to a pipe axis, or it can extend between the Extend tubes so that the swivel axes in any Way can go.
  • Any suitable one can also be used Use a connector, such as a connector for the face of a pipe. This connector can be used if necessary can also be realized by an extruded profile.
  • the invention Solution the implementation of a secure anchor the lower shell allows without a fastener would touch the pipe to be covered.
  • the fastener can be a square or Have hexagon head, and the dimensions of the channel can be chosen so that the fastener as a bolt is also held against rotation.
  • the measure is the contact surface on the inside of the lower shell and the top shell is then somewhat reduced, for example by about 10%. However, this has proven to be uncritical highlighted, and in particular, no notch effects in the pipes initiated.
  • the joint tabs a correspondingly adapted To give length.
  • pipe diameters compensate between 48 and 52 mm without any problems.
  • the wall thickness is provided to reduce the top shell significantly.
  • the reduction does not affect the area of the joint and that of the Clamping element, but only the area in between.
  • the scaffold coupling 10 shown in FIG. 1 has an upper shell 12 and a lower shell 14, which has a joint 16 are interconnected.
  • tensioning element 18 On the side opposite the joint is a tensioning element 18 provided that in the illustrated embodiment is designed as a hammer head screw with wing nut.
  • a hammer head 20 is designed as a cross bolt, which in one Groove 22 of the lower shell abuts.
  • the groove 22 is semicircular, so that a large-scale plant is created.
  • the bolt shaft 24 passes through transverse grooves, which laterally in Upper shell 12 and lower shell 10 extend into it and one Have width that corresponds to the diameter of the bolt shaft 24 equivalent.
  • the transverse groove in the lower shell 14 is through a contact pin 26 closed, the received in a passage recess that passes through the lower shell 14.
  • This solution can be the tensioning element between that shown in Fig. 1 Position and the position shown in Figs. 2 and 3, so about an angle of 45 °.
  • the wing nut 28 is screwed onto the bolt shaft 24, that is Clamping element captively attached to the lower shell 14.
  • the upper shell 12 and the lower shell 14 consist of extruded profiles, for example from an aluminum alloy.
  • the upper shell 12 has a passage recess 30 and the lower shell 14 a passage recess 32 on.
  • tabs 36 are provided, which together with the passage recesses each provided with rivets 38, 40, which from Fig. 4 can be seen.
  • the lower shell 14 has a concave and the upper shell 12 has a convex configuration. at This solution dictates that the hinge axis runs through the passage recess 30, while the Tab 36 is not pivotable relative to the lower shell 14 is. It goes without saying that any one instead other suitable design can be selected, that is also an embodiment, for example, that has a low horizontal Displacement between upper shell 12 and lower shell 14 allows.
  • the lower shell 14 has an adapter 42.
  • the adapter is as projecting neck 44 formed with a fastener 46 interacts.
  • the fastener 46 passes through the lower shell 14 starting from a channel 48, the fastener head 50 receives.
  • the neck 44 has any suitable and form-fitting configuration on.
  • the connecting part 52 has an essentially H-shaped one Building on. In its upper area it is designed that it has full surface support on the adapter 42 over the entire surface is applied. The middle leg 58 of the connection part 52 is penetrated by the fastener 46 so that it is possible to establish a very stable connection between to produce the connecting part 52 and the lower shell 14.
  • Fig. 2 From Fig. 2 it can be seen how the scaffold coupling according to the invention can be solved.
  • the wing nut 28 is so far against screwed clockwise that they are over a nose 60 of the upper shell 12 can pivot, namely in the open Position according to Fig. 2. In this position is the upper shell 12 freely pivotable about the joint 16.
  • the clamping element 18 abuts the investment pin 26.
  • the upper shell 12 can also be further swing up, in a position that is essentially extends at right angles to the position shown in FIG. 1. Due to the shape of the upper and lower shell is a further pivoting prevented.
  • FIG 4 is a modified embodiment of the invention Scaffold coupling 10 can be seen.
  • the transverse groove 64 extends in the upper shell 12 in same way as in the embodiment according to FIGS. 1 to 3.
  • the transverse groove 66 in the lower shell 14 is laterally not completely open to the outside, but forms an investment shoulder, so that the investment pin 26 is unnecessary.
  • This Solution is somewhat more expensive to manufacture after Milling work is required, but provides a safe one Swivel position for the clamping element 18.
  • the embodiment according to FIG. 5 is characterized by the use of exactly the same lower shells as for the Embodiment according to FIG. 4.
  • the adapter 42 is the same Wise trained, and also the channel 48.
  • a rivet 68 passes through the lower shell 14 as a fastening element 46 and stores another scaffold coupling on the scaffolding coupling 10 pivotable about a vertical axis.
  • the adapter 42 has a quite large and flat underside 70, so that a tilt-proof swivel bearing is possible.
