Definitions

  • the invention relates to a snow guard nose, consisting of a fastening part running approximately in the direction of the roof pitch and a catching part provided for the snow guard, approximately perpendicular to it, and a supporting part connecting the upper end thereof to the fastening part, the catching, supporting and fastening part being bent by bending a single one strip-shaped metal strip are formed, and wherein in the support part at least two in the longitudinal direction extending over its entire length, side by side beads are provided.
  • Such a snow guard nose was e.g. known from AT-PS 376 472.
  • the catching, supporting and fastening part are each provided with two beads projecting into the interior of the space delimited by these parts, between which a stiffening insert is held.
  • DE-AS 1 125 137 proposes welded solid wall girders in which the web plate is provided with vertical bends at intervals and the web plate consists of individual pieces that extend from the bend to the bend and are welded to the bends, the web plate pieces alternately in are bent up in such a way that the folds lie alternately on both sides of the central bridge plane.
  • these brackets are not intended to be a snow guard and are not suitable for this, but they have a high section modulus due to the alternate bending of the web plate pieces.
  • snow catchers are formed from a long sheet metal strip which is bent at one end to form the catch part at an angle of approximately 90 ° C. and at the end of the catch nose is bent again at an angle of approximately 45 ° C. to form the support part.
  • One or two beads are arranged in the catch and / or support part for stiffening. However, this stiffening has proven to be insufficient.
  • the aim of the invention is to avoid the disadvantages of the known snow guard lugs and to propose one of the type mentioned at the outset which is distinguished by a high degree of rigidity and can be produced with little effort.
  • the section modulus is increased significantly due to the bead in the opposite direction, so that the insert can be found long without insert and therefore the manufacture of a snow guard nose according to the invention is considerably simplified and still achieves a very high degree of rigidity even when using relatively thin sheet metal strips becomes.
  • a preferred embodiment of the invention is that the recess of the two outer beads near the edge is formed in the same direction. Such a design enables substantial stiffening with minimal additional effort.
  • the oppositely recessed bead can be formed with a recess that increases constantly towards the longitudinal center.
  • a conical bead leads to a further increase in the bending strength.
  • the central bead of the catching part can be designed to extend approximately to the central region of the fastening part.
  • Such training advantageously prevents For example, a lifting of the roof area caused by very high snow loads acting on the catching part, in particular of the middle area.
  • a snow guard nose formed from sheet metal is composed of a fastening part 2 adjacent to the roof surface, a catching part 3 arranged perpendicularly to this and a supporting part 4 connecting it to the fastening part.
  • Both the catching and supporting part 3, 4 have three beads 5 arranged parallel to one another and running in the longitudinal direction of the parts.
  • the depression of the central bead 5 of the support part 4 is formed in the opposite direction compared to the depression of the adjacent beads 5.
  • the bead shape is semicircular, but it can also be trapezoidal or the like.
  • the two outer beads 5 of the support part 4 can be recessed in the direction of the catching part 3, while the central bead 5 is then shaped in the opposite direction.
  • the fastening part 2 also has two beads 6 in its area lying between the catching and supporting part 3, 4.
  • the snow guard nose 1 shown in FIGS. 3 and 4 has a specially designed central bead 7 in the region of the support part 4. This has a depression 8 directed in the direction of the catching and fastening part 3, 2, which increases constantly in the direction of the longitudinal center of the bead. This conical bead 7 ensures a particularly stable formation of the snow guard nose 1.
  • the central bead 9 extends from the catching part 3 to the central region of the supporting part 2 and thereby prevents the supporting part from lifting when the snow load acting on the catching part 3 is too high.
