Definitions

  • the present invention relates to a snow and / or icing device having the features of the independent claim 1 and a ridge inclined by ridge eaves and profiled in the direction of slope roof surface with a snow and / or Eisfangvorraum with the features of the independent claim. 7
  • snow guard systems for gable roofs are intended to largely prevent the slipping of snowboards and ice sheets.
  • conventional snow guard systems can also be mounted. Since these run parallel to the eaves direction and thus transversely to the profiling of the roofs, gaps are formed below the base or base sections, since the snow guard systems or snow guards do not extend into the profile valleys of the profiled roof surfaces but are normally mounted on the profile elevations.
  • the uncovered troughs can cause problems, as the gaps are often large enough to allow ice sheets to slip through, separating from the surface of the roof and allowing it to slip downwardly largely unhindered.
  • the release of such slabs or ice sheets is particularly favored for sheet metal roofs, as they can be subject to strong temperature fluctuations.
  • roofs that are not thermally insulated the roof surface temperature varies greatly, while the snow on the roof has an insulating effect.
  • the roof layer on the roof can be thawed several times and turned into ice, allowing the slab to slip off and slide down the profile valley below the snow guards. In such cases, the snow guards system can fulfill its intended protective task only insufficient.
  • the JP 110 22 123 A ( JP 35 14 952 B2 ) discloses a roof snow catcher with an angle profile for a folding roof. At the angle profile a wire-shaped arm is arranged, which is connected via curved hangers with the angle profile. The arm should serve to restrain snow and ice.
  • a similar snow guard device is further from the JP 2007 211 444 A known.
  • the arms are formed as plate-shaped sheets, which are individually mounted on a rail.
  • the disclosure DE 1759 272 A a snow and ice catcher for corrugated roofs, in which at predefined locations have lobes in the direction of the roof surface.
  • the known snow guard devices for profiled roof surfaces largely fulfill their intended purpose. However, they sometimes have only insufficient mechanical stability and all require a considerable additional installation effort, since they are not universally suitable for different profile widths and / or depths of the roof surfaces. The user can not help to install the additional protection devices after mounting the base rail individually in the appropriate places to cover the profile valleys.
  • a universally applicable snow and icing device is from the WO 2007/045724 A1 known.
  • This document shows a snow and / or icing device in which in the mounted and in the preassembled state permanent individual tongues protrude from the device. The tongues should prevent the sliding down of snow and ice. An injury to the tongues of the snow and icing device during assembly can not be ruled out.
  • the object of the present invention is seen to provide a pre-assembled and universally usable ice and / or snow guard device which is suitable for differently profiled roof surfaces.
  • the invention proposes a snow and / or icing device for roof surfaces, which are inclined by ridge in eaves direction and profiled in the direction of inclination, with the features of independent claim 1 before.
  • This snow and / or icing device comprises a transversely to the direction of inclination of the roof surface extending rail having an L-profile with an approximately parallel to the roof surface extending base portion and an adjoining, opposite the roof surface towering barrier.
  • the device according to the invention is characterized by a plurality of tines formed in the base section, at least some of which enclose an acute angle with the surface of the base section and point in the firing direction obliquely to the roof surface.
  • the tines facing the roof surface are at least those which are arranged in the region of wave or profile valleys of the profiled roof surface.
  • Tines not required for the functioning of the snow and / or icing device are those which are arranged in the region of wave crests or profile elevations of the roof surface. These tines are normally not brought into a so-called. Operating position, but remain in their original starting position, parallel to the plane of the base portion.
  • the tines are each arranged in profile valleys of profiled in the direction of slope roof surface, they can be adapted to the different profiles, both in terms of the depth of the profile valleys and their width and distances from each other.
  • These troughs or profile valleys may, for example, be referred to as lower chords of the profile.
  • the wave crests or profile elevations may, for example, also be referred to as upper chords of the profile. So if in the context of the present application of profile valleys or lower chords and profiled surveys or upper chords is mentioned, so this refers to all types of regularly profiled transverse to the eaves eaves direction roof surfaces, whether they are now edged or wavy profilings.
  • the prongs are each integrally formed with the base portion.
  • the base portion may be formed integrally with the barrier.
  • the barrier may, for example, be formed as a continuous sheet, optionally with openings, which may in particular be punched out.
  • the Tines are punched out in the base section.
  • the tines can each be bent or bent from the plane of the base section in the direction of the roof surface, so that they can be ideally adapted to a wide variety of roof contours and profiles.
  • all existing tines must be bent down to the roof surface, but preferably only those that are arranged in the range of profile valleys. Unnecessary tines remain in the unbent state in the base section.
  • the individually bendable tines allow the assembly of the rail on the roof and the subsequent activation of each required tines to protect vulnerable areas below the roof optimally against sliding down snow or loosening ice sheets.
  • These snow or ice plates remain hanging on the bent down in the direction of the roof surface and pointing in the direction of the fire tines and get caught there, the tines are bent by the adjacent snow or ice loads in an advantageous manner down towards the roof surface, which a yielding or failure of the protective function reliably prevented.
  • the tines can each be designed as tongues which are bent downwards along a bending and / or bending line running parallel to the longitudinal extension direction of the L-profile in the direction of the roof surface.
  • the unneeded tines which are arranged in the region of profiled bumps, wave crests or upper straps, on the other hand, are not bent downwards, but remain in the plane of the base section regardless of their stamped outline.
  • the tines may be formed as strips of constant width with edged or rounded tip.
  • the tines each taper toward their free ends facing the roof surface and / or taper toward their free ends.
  • the L-profile rail comprises a flat or slightly arched and / or corrugated base portion and a leg adjacent to a longitudinal side.
  • a plurality of molded and punched tines is provided, which are each formed as tongues, which are angled along a direction parallel to the longitudinal direction of the L-profile bend and / or bending line.
  • the L-profile rail can in particular be formed by a metal profile section, in which the prongs are preferably regularly spaced from each other and each having equal lengths.
  • the L-profile rail may, for example, have a sheet thickness of 2 to 3 mm, wherein the material used may be, in particular, painted or powder-coated steel sheet, optionally with electrogalvanizing or hot dip galvanizing, an enamel coating or the like.
  • the material used may be, in particular, painted or powder-coated steel sheet, optionally with electrogalvanizing or hot dip galvanizing, an enamel coating or the like.
  • other types of metals are also suitable for producing such rails, such as copper, stainless steel (stainless steel grades, aluminum or corresponding copper- or aluminum-containing or -based alloys.)
  • Sensible dimensions can be, for example, length units of the profile rail between about 0.5 to about In principle, however, the profile rail can have almost any desired lengths, for example the base section can have a width of between 80 and 150 mm, as can the barrier section
  • the punched-out metal tongues of the tines can, for example, be lengths between 50 and 120 mm
  • the distances of the tongues from one another
  • a plurality of elongated holes may preferably be provided in the base section to form the base section easy to screw on the roof surface any mounting on wave crests or profile elevations of the profiled roof surface, regardless of the respective profile pitches and / or the distances of the wave crests and / or troughs or the profile elevations or profile sinks.
  • the barrier portion may be slightly bent at its upper edge in the firing direction of the roof. Basically, it is irrelevant for the function, whether the base portion and / or the barrier are curved or profiled flat or in the longitudinal direction of the rail and how this curvature or profiling dimensioned, if available. If such a profiling is present at least in the base section, the prongs preferably also have the profiling, which, however, does not impair or influence their function in any way.
  • the invention comprises a rooftop surface inclined from the ridge in the eaves direction and profiled in the direction of inclination, with at least one continuous and interrupted snow and / or icing device in the vicinity of a eaves, according to an embodiment of the previous description Rows of such snow and / or Eisfangvoriquesen be mounted on the roof surface, optionally in continuous configuration or as a single or multiple interrupted rails that can be arranged in the parallel rows, for example, offset from each other on the roof surface, if the expected snow loads require or make sense.
  • the pre-cut tines which lie in the area of wave or profile valleys of the profiled roof, can be angled with simple tools and bent down so they can fulfill their actual task of stopping slipping snow and / or ice loads in an optimal manner.
  • wave troughs and wave crests of the profiled roof are mentioned, all conceivable shapes and contours of profiled valleys and profiled elevations of the profiled roof are therefore included in the same way.
  • These troughs or profile valleys may, for example, be referred to as lower chords of the profile.
