Definitions

  • the present invention relates to a device for retaining the snow accumulated on the roofs of buildings made of sheet metal with rounded ribs or at sharp angles to prevent it from pouring in whole blocks outside the roof especially during the period of the melting.
  • the Applicant has described a device made in one piece from stamped sheet metal and which, in general, comprises a narrow strip, parallel to the roof plane and ensuring attachment to said roof at the top of the ribs of the sheet and, perpendicular to this strip, therefore to the roofing plane, two parts oriented in opposite directions, one disposed between the ribs and making it possible to retain the thin layers of snow while allowing the passage of water and the other, perpendicular above the roof plane and allowing to retain the larger layers of snow.
  • the snow-retaining device according to the invention on ribbed sheet roofs is constituted by a single-piece assembly comprising two parallel spaced edges allowing it to be adapted on the tops of two contiguous ribs of the roof and, between these two edges, two parts substantially perpendicular to the roof plane, one being arranged between the ribs and making it possible to retain the thin layers of snow while allowing the passage of water, the other arranged above the roof plane and making it possible to retain the larger layers of snow, the device according to the invention being characterized in that the two aforementioned parts are arranged in the extension of one another and form a barrier which is extended, continuously going downstream of the roof, by a continuous plane (ramp) forming an angle less than 45 ° and preferably close to 30 ° relative to u plane of the roof, the end of the upstream part serving to block the snow and which is situated between the grooves as well as that of the continuous plane (ramp which extends it), being spaced from the bottom of said grooves.
  • a continuous plane ramp
  • the upstream part used to block the snow will be designated by the term "barrier" and, the downstream part in the form of an inclined plane will be designated by the expression "ramp".
  • the device according to the invention designated by the general reference (1) and which is intended to ensure the retention of snow accumulated on roofs of corrugated sheet building (or the like) is manufactured in one piece, for example in a stamped sheet.
  • This say positive consists of two lateral edges (2, 3), parallel, spaced from each other, whose shape is such that they can come to marry the top of two ribs (4, 5) of the roof.
  • the roof being produced from a sheet with ribs with sharp angles, the edges (2, 3) will have a flat surface (6, 7) which rests on the top of each of the ribs and flaps. (8,9) which bear on the outer faces of said ribs (4, 5).
  • a barrier (11) for retaining snow comprising two parts, arranged in the extension of one another, a part (11 ) located below the plane P passing through the top of the ribs and the end (12) of which is spaced from the bottom (13) of said ribs (in the present case the spacing E is approximately 0.5 to 0, 8 cm), which serves to stop the thin layers of snow while letting the water pass and an upper part (14) overflowing above the plane P passing through the tops of the ribs and which has the function of retaining the thick layers of snow.
  • This barrier (11) is, when the device is placed on the roof, located on the upstream side of the roof.
  • a continuous ramp (15) which, preferably, also extends inside the space between the ribs near the bottom (13), the spacing with this background being generally equal to the spacing E of the barrier (10).
  • the barrier (10) is disposed practically orthogonally relative to the plane of the roof while the ramp (13) forms, in turn, an angle less than 45 ° and preferably close to 30 ° relative to said plane.
  • These two barrier (10) / ramp (15) elements are connected to the lateral edges (2, 3) by continuous surfaces (16a, 16b) which form connection zones having rounded edges.
  • the device is fixed to the ribs for example by means of screws (17, 18), a seal (23) being able to be provided at this level.
  • these fixing means have not been shown.
  • Such a snow stop device the subject of the aforementioned French patent 2,575,455, has the same advantages in that it makes it possible to ensure effective retention of the snow. In addition, it eliminates any risk of tearing of the bindings, in particular as a result of a rise in ice during a period of frost, since the ramp (15) and the barrier (10) form a cavity allowing ensure expansion. In addition, due to the very structure of such a device, there is a self-tightening against the ribs during the thrust exerted by the snow, self-tightening which avoids any unnecessary stress on the fastening means.
  • such a device can also be adapted to make it possible to detect an overload of snow.
  • a conventional proximity detector (20) The triggering of this detector is obtained by providing in the lower part of the barrier (10) a flexibility zone produced by means of two slots (21, 22).
  • the barrier (10) can be moved against the detector (20) and trigger an alarm.

Claims (5)

1. Vorrichtung zum Rückhalten von Schnee auf einem Dach aus geripptem Blech, gebildet durch einen einstückigen Zusammenbau (1), mit zwei voneinander beabstandeten, parallel zueinander verlaufenden Rändern (2, 3), die es ermöglichen, auf den Spitzen zweier benachbarter Rippen (4, 5) des Daches und zwischen diesen Rändern (2, 3) zwei im wesentlichen rechtwinklig zur Dachebene verlaufende Teile anzubringen, von denen einer (11) zwischen den Rippen angeordnet ist und das Rückhalten von weniger dicken Schneeschichten ermöglicht, wobei der Durchtritt von Wasser freigelassen wird, und der andere (14) oberhalb der Dachebene angeordnet ist und das Rückhalten von größeren Schneeschichten ermöglicht, dadurch gekennzeichnet, daß die beiden Teile (11, 14) jeweils in der Verlängerung des anderen angeordnet sind und daß diese eine Barriere (10) bilden, die durch eine weitergeführte Ebene (15) (oder Rampe) fortgesetzt ist und zwar derart, daß sie in stromabwärtiger Richtung des Daches fortgesetzt ist, wobei diese einen Winkel unterhalb von 45°, und vorzugsweise etwa von 30° mit der Dachebene bildet, wobei das äußere Ende (12) des Teiles (11) und das der geneigten Ebene (15) jeweils vom Boden (13) der Rippen beabstandet ist.
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß sie aus einem einzigen Stück hergestellt ist, beispielsweise durch Tiefziehen einer Metallplatte, oder durch Formen eines Kunststoffmaterials, wobei die Barriere (10) durch die beiden Teile (11, 14) und die Rampe (15) gebildet ist, sowie über abgerundete Bereiche mit den seitlichen Rändern (2, 3) verbunden ist, die das an Ort und Stelle bringen und Ausrichten der Vorrichtung ermöglichen.
