Definitions

  • the present invention relates to a clamp for securing snow-stop devices to metal plates of roofing and the like.
  • the latter are also seamed together in the direction perpendicular to the slope of the roof pitch order to ensure the their stability.
  • a clamp according to the preamble of Claim 1 is known from DE 9103193 U1 .
  • the technical problem which is posed, therefore, is that of providing a clamp for securing snow-stop means to metal plates for roofing and the like, which is able: to allow rapid and reliable fixing to the seaming lines of the metal plates; fasten different types of snow-stop means without having to vary the form of the clamp; allow an improved relative movement caused by expansion of the metal plates following variations in temperature.
  • the clamp should be easy and inexpensive to produce and assemble, have a low weight and small dimensions, but have optimum mechanical strength properties.
  • a securing clamp according to the present invention comprises:
  • the first clamping jaw 10 has a convex bottom part suitable for joining together with cylindrical seaming surfaces and provided with ribs 14 extending in the vertical direction Z-Z and designed to increase the mechanical strength of the jaw, thereby allowing its overall thickness to be reduced so as to allow easier machining with a reduction in the amount of material required and therefore in the overall weight, this also allowing savings in the final costs.
  • the first clamping jaw 10 has recesses 11 extending towards the inside and aligned with each other and situated opposite each other in the vertical direction Z-Z; said recesses 11 have a respective side 11a, 11b corresponding to the associated base 10a,10b, which is open outwards, and inner side 11c with a semicircular shape.
  • the first clamping jaw 10 also has a pair of through-holes 12 respectively arranged in the vicinity of the longitudinal edges of the smaller base 10b and on opposite, preferably symmetrical, sides relative to the corresponding seat 11.
  • the first clamping jaw 10 has two openings 13 which are suitable for receiving a bolt 24a which can be joined to a nut 24b for fixing a second clamping jaw 20 to the first clamping jaw 10.
  • the second clamping jaw 20 is in turn provided with a seat 21 which is open along the side 20a, situated at the bottom during use; said seat 21 has a semicircular inner side 21c with a radius corresponding to the radius of the inner side 11c of the seat 11 of the smaller base 10b of the first clamping jaw 10; the second clamping jaw 20 is also provided with two holes 23 which are arranged symmetrically relative to said seat 21 and which, in the working condition, are designed to be arranged coaxially with the openings 13 in the first clamping jaw 10 of the clamp so as to allow the respective bolt 24 to pass through.
  • the first clamping jaw 10 of the clamp also has a respective boss 15 projecting inwards in the transverse direction Y-Y perpendicular to the plane of the clamping jaw and designed to keep the said clamping jaw spaced from the riveted flange 1a of the metal plate 1 and facilitate the movements thereof due to heat expansion.
  • the second clamping jaw 20 has a convex form and respective bosses 25 projecting inwards in the transverse direction Y-Y so as to improve the static arrangement of the system once tightening has been completed.
  • Figs. 3a,3b show an auxiliary element 30 of the clamp 10, in the form of a spring piece having the form of an "overturned U", each wall 30a of which has a respective semicircular seat 31 which is open along the respective free edge 30b.
  • each wall 30a of the spring piece 30 has a tooth 33 projecting towards the inside of the U and designed to be inserted inside the respective corresponding hole 12 close to the smaller base 10b of the first clamping jaw 10 of the clamp.
  • the clamp according to the invention may be applied to the riveted joining flange 1a of the metal plates 1 projecting in the vertical direction Z-Z, by joining together the first clamping jaw 10 and the second clamping jaw 20 on opposites sides of the riveted flange 1a and tightening together the first clamping jaw 10 and the second clamping jaw 20 by means of the bolts 24a and the respective nut 24b.
  • the clamp is ready to receive and fix the snow-stop means which may consist of a grille 40 ( Figs. 6a, 6b ) or tubular elements 50 ( Figs. 7, 8 ).
  • a grille 40 which has a rigid reticular structure consisting of longitudinal members 41 and transverse members 42, in order to fix it further auxiliary parts are not required since, for retention purposes, it is merely required to insert the transverse longitudinal member 41 inside the bottom seat 11 of the clamp.
  • first clamping jaw 10 second clamping jaw 20 and the spring piece 30 may be implemented in a manner equivalent to that of the embodiments described above.
