Definitions

  • the invention relates to a clamping element for securing snow and ice on a snow guard having roofs, wherein the clamping element has two substantially angularly disposed legs and is supported with the free, first ends of the legs on the roof and in the region of the second end of the first leg on Snow tube abuts.
  • Such clamping elements which are also called ice holder, are for example from the EP-A-0 939 180 known.
  • This ice holder has a substantially W-like shape and is clamped between the snow tube and the roof surface.
  • the ice holder is under spring tension at the bottom of the snow tube.
  • the voltage applied to the snow tube portion or portion of the ice holder is curved according to the shape of the snow catcher tube, whereby the ice holder should be secured against slipping, so that the ice or snow on the roof is held back against slipping.
  • it has been shown that such ice holders can only protect a limited snow load and when this snow load is exceeded, the snow or ice ice holders pushes under the snow catcher pipes. The ice holder then provides no security against slipping of the ice or snow from the roof.
  • the invention has the object of providing a clamping device of the type mentioned in such a way that it provides greater security against the slipping of ice and snow.
  • the clamping element according to the invention has the significant advantage that it is not only clamped between the snow skirt and the roof surface, but that it is also supported laterally on the snow pipe, so that it can not be easily pushed by the snow or ice under the snow pipe.
  • the T-shape of the clamping element has the double function that the clamping element can be clamped between the roof and snow catcher pipe, but that the clamping element itself is also supported in the direction of slipping snow or ice on the snow pipe or obstructed by the snow pipe against displacement.
  • the shape of the snow tube does not matter with regard to the shape of the clamping element.
  • the second end of the second leg engages around the snow tube upper side at least partially. This ensures that the clamping element is fixed to the snow tube.
  • the clamping element is fixed in this way both in the slipping and in the opposite direction.
  • the second leg abuts the snow tube in the area of the second end.
  • the second leg may be formed in the region of the second end in accordance with the contour of the snow catcher tube.
  • the two limbs lie in the regions of their second ends at substantially opposite ends on the snow tube.
  • the ends of the two legs embrace or surround the snow tube over a large angle, whereby the secure hold is generated.
  • the clamping effect is inventively generated in that the snow tube is encompassed by the two legs by more than 180 °. On the one hand, the clamping element is thus on On the other hand, the clamping element between the snow tube and the roof surface is jammed. This double jamming is in the prior art according to the EP-A-0 939 180 not achieved, which is why there the holding forces according to the invention can not be generated.
  • the distance between the snow tube and the roof surface should be so large, which could be caused for example by bending of the roof, although the deadlock between the snow pipe and the roof surface loosen, but the clamping element is still fixed via the clamp connection directly on the snow pipe.
  • the wrap-around angle is between 250 ° and 200 °, in particular between 240 ° and 220 ° and preferably between 235 ° and 225 °.
  • the assembly is slightly more expensive, since the Aufrastvorgang requires greater assembly forces, however, ensures a larger wrap angle and larger retention forces against peeling of the clamping element.
  • the first leg has at least one, in particular two, projecting in the direction of the snow catcher embossing. These embossings serve to the clamping element against peeling against the Aufreastcardi, that is to ensure against the Abloiscardi the snow and ice.
  • the clamping element When snapping the clamping element on the snow tube so not only the second end of the second leg must be pushed over the collection tube, but the collection tube must also run over the two imprints.
  • the snow tube then lies between the adjacent to the second leg second end of the first leg and the imprints.
  • the embossments touch the snow tube or lie on the embossments on the snow tube, whereby any game is turned off, so that the clamping element, for example, by wind no noise, especially rattling generated.
  • the embossings can be designed as point or line embossing.
  • the clamping element is integrally formed, in particular as a sheet metal bent part.
  • the production and / or the bearing holder is considerably simplified in this way.
  • the second leg is designed in particular double-walled, which is explained in more detail in the following description, in which reference is made to the drawing. A bending of this second leg is additionally counteracted in this way.
  • the snow tube and the clamping element made of the same material.
  • the clamping element can be made of copper, a copper alloy, stainless steel, galvanized Sheet steel, made of an aluminum alloy and so on.
  • the two legs which form a T-shape, at an angle of 70 ° to 110 °, in particular from 80 ° to 100 °, in particular orthogonal to each other.
  • the two legs can also assume a shape according to the Greek letter lambda ( ⁇ ).
  • the second leg forms the T-bar of the T-shaped clamping element.
  • FIG. 1 is a section of a total of 10 designated roof recognizable, which is composed of a plurality of metal tracks 12, wherein the metal tracks 12 are connected to each other via a fold 14.
  • a snow catcher tube 16 of a snow guard system which is attached to the folds 14 each with a clamping fist 18.
  • a distance 22 between the snow tube 16 and the surface 20 of the roof so there is a distance 22 (see FIG. 2 ), so that between the snow tube 16 and the roof 10 is a designated overall clamping element 24 detent and clamped fastened.
  • the clamping element 24 is snapped in the direction of the arrow 26 between the snow pipe 16 and the roof 10 and on the snow pipe 16.
  • the clamping element 24 has according to FIG. 2 a first leg 28, the free end 30 rests on the surface 20 of the roof 10.
  • the second end 32 abuts a second leg 34 such that the two legs 28 and 34 form a T-shape, wherein the second leg 34 forms the T-bar.
  • the free end 36 of the second leg 34 is also on the surface 20 of the roof 10, whereas the second end 36 of the second leg 34 extends beyond the snow tube 16 and partially engages.
  • FIG. 2 It can clearly be seen that the region of the second end 32 of the first leg 28 rests linearly on the snow tube 16, whereas the region of the second end 38 of the second leg 34 is shaped in accordance with the curvature of the snow tube 16 and thus rests flat against the snow tube 16.
  • the wrap angle ⁇ of the second end 38 of the second leg 34 is about 150 °
  • the wrap angle ⁇ of the two legs 28 and 34 is about 235 °.
  • two embossments 40 are provided, which protrude in the direction of the snow tube 16 and abut against this.
  • the embossings have the advantage that the first leg 28 does not have to be adapted to the shape of the snow tube 16 and still be locked on the snow tube 16.
