Definitions

  • the invention relates to a snow holding device for mounting on roofs or corresponding surfaces with two spaced profiles which have at least one longitudinal wall and are connected by at least one web running between the longitudinal walls.
  • Such a snow holding device is disclosed in DE-U-8 229 095; two angle bars are connected to each other like a ladder by crossbars and inserted into the side bracket.
  • This fence-like element has the considerable disadvantage that moisture can accumulate on the angled strip protruding below, in particular if the device runs somewhat obliquely due to improper fastening. Then the lower angle forms a water channel in which the water stops and creates corrosion.
  • the protruding parts of this snow holding device endanger a user, for example a fitter.
  • the inventor has set itself the goal of producing a low-corrosion element that is easy to manufacture and can be assembled easily and of low weight, which is done according to the invention in that the profiles are designed as hollow profiles with no outwardly projecting parts and are integral with the profile web the way of extrusion are made of aluminum or an aluminum alloy. In addition, the mutually facing inner walls of the hollow profiles are inclined away from the profile web.
  • the snow holding device according to the invention is easy to manufacture by the extrusion process and without any protruding parts. Thanks to the extrusion process, the hollow profiles are completely closed and as a result cannot absorb any liquid. The inclined position of the two inner walls facing each other is of particular importance; as a result, the above-described collecting channel for liquid cannot arise even if improperly installed.
  • the inner wall with the profile web encloses an inclination angle of 110 to 150 °, preferably 140 °, and ensures to a particular degree that neither snow nor water can remain on the inner wall.
  • This advantage can be supported according to the invention by a slight curvature of the hollow profile cross section of the inner wall.
  • the longitudinal axis of the profile web as a plane of symmetry;
  • the same profile contours are arranged on both sides of this plane of symmetry, for example a hollow profile with an intermediate strip provided between the inner wall and the side wall and inclined to both walls.
  • this particularly pleasing shape offers particularly little contact surfaces for snow or liquid to remain lying down, but also makes installation easier, since the profile according to the invention is never installed with a “wrong” side.
  • a rectangular profile results, which adjoins the profile web with a corner, the adjacent rectangular sides forming the inner walls.
  • a profile strip 10 which can be fixed on a roof and has a height i of 150 mm, for example, for holding roof avalanches, consists of a profile web 11 with hollow profiles 12 arranged on both sides.
  • the interior 13 of that hollow profile 12 is delimited by a section of the profile web 11, a longitudinal wall 14 perpendicular thereto, a side wall 15 parallel to the profile web 11 and an inclined inner wall 16; the latter includes an angle w of preferably 140 ° with the profile web 11.
  • recesses 17 are made, for example stamped, which form intermediate webs 18.
  • the longitudinal axis of the profile web 11 is a plane of symmetry E for the extruded profile strip 10 a .
  • the profile web 11 of a height h at both ends at an angle t of about 70 °, two inner walls 16, each of which adjoins at an angle n an intermediate strip 16 a , which merges into the side wall 15.
  • the longitudinal wall 14 is divided by that plane of symmetry E in the middle.
  • Fig. 3 is a hollow profile 12 with a square Recognize cross section, which is formed with a corner on the profile web 11.

Abstract

Un dispositif pour retenir la neige destiné à être monté sur des toitures ou des surfaces inclinées similaires comporte deux profilés (12) écartés l'un de l'autre, présentant au moins une paroi longitudinale (14) et reliés par une âme (11) s'étendant entre ces parois. Ces profilés (12) sont constitués de profilés creux et sont extrudés en une seule pièce avec l'âme (11).

Claims (10)

1. Dispositif pour retenir la neige, destiné à être- monté sur des toits ou des surfaces inclinées semblables, comprenant deux profilés (12) s'étendant à distance l'un de l'autre, qui possèdent au moins une paroi longitudinale (14) et sont reliés l'un à l'autre par au moins une entretoise (11) s'étendant entre les parois longitudinales, caractérisé en ce que les profilés sont constitués par des profilés creux (12) qui ne présentent aucune partie faisant saillie vers l'extérieur et sont produits, d'un seul tenant avec l'entretoise (11), par extrusion d'aluminium ou d'alliage d'aluminium.
2. Dispositif selon la revendication 1, caractérisé en ce que des parois intérieures (16) des profilés creux (12), parois qui sont dirigées l'une vers l'autre, s'étendent à partir de l'entretoise (11) en s'écartant l'une de l'autre sous une inclinaison.
3. Dispositif selon la revendication 1 ou 2, caractérisé en ce que chaque profilé creux (12) possède une paroi latérale qui se raccorde à la paroi longitudinale (14) et que la paroi intérieure (16) s'étend entre cette paroi latérale et l'entretoise (11).
4. Dispositif selon une des revendications 1 à 3, caractérisé en ce que la paroi intérieure (16) renferme avec l'entretoise (11) un angle d'inclinaison (w) de 110 à 150°, de préférence de 140°.
5. Dispositif selon une des revendications 1 à 4, caractérisé en ce que l'axe longitudinal de l'entretoise (11) définit un plan de symétrie (E).
6. Dispositif selon une des revendications 1 à 5, caractérisé en ce qu'une bande intermédiaire (16a) s'étend entre la paroi intermédiaire (16) et la paroi latérale (15), elle-même parallèle à l'entretoise (11), la bande intermédiaire étant inclinée à la fois par rapport à la paroi intérieure et par rapport à la paroi latérale.
7. Dispositif selon la revendication 1 ou 5, caractérisé en ce que le profilé creux (12) possède une section droite essentiellement rectangulaire, de préférence carrée, et que le profilé creux se raccorde à l'entretoise (11) par un angle, de manière que deux parois voisines, en section droite, forment des parois intérieures (16).
8. Dispositif selon une des revendications 1 à 7, caractérisé en ce que la paroi intérieure (16) possède une courbure en section droite.
9. Dispositif selon une des revendications 1 à 8, caractérisé en ce que des évidements (17) sont formés par découpage dans l'entretoise (11).
10. Dispositif selon la revendication 1 ou 9, caractérisé en ce que les évidements (19) forment des entretoises intermédiaires (18) entre eux.
