Definitions

  • the present invention relates to a sheet metal roofing.
  • the present invention is a well-known type of roofing system which comprises a plurality of metal sheet panels which have two folded ends and arranged to be couplet side by side by snap overlapping and to be anchored to supporting blocks which are spaced from one another and fixed to an underlying load-bearing purlin.
  • the main object of the present invention is to provide a roofing structure of the type described above in which installation difficulties are eliminated and installation can be performed without resorting to troublesome operations or using special equipment.
  • Another object of the present invention is to provide a walkable roofing structure which is weather-proof for long time without requiring maintenance.
  • Another object of the present invention is to provide a roofing structure easy to be produced and thus having a low production cost, whereby being also advantageous from an economic point of view with respect to other commercially available roofing structures.
  • a folded metal sheet roofing structure which comprises: a plurality of metal sheets having two non-adjacent edges complementarily folded or otherwise shaped so as to allow mating of two contiguous metal sheets by partly overlapping snap engagement; a multiplicity of supporting and holding blocks to be anchored to a load-bearing purlin for the roofing and having a base portion with two raised portions arranged side by side of a respective recess; and characterized in that one raised portion of each supporting block has a diverging inclination with respect to the other and in that each one of said recesses is externally adjacent to an inclined-plane cradle which is inclined towards its respective raised portion, and has its access delimited by a shoulder or abutment tooth on one side and by inclined-plane surfaces at its other side, thereby allowing anchoring and quick overlapping coupling of one metal sheet with a contiguous one simply by applying pressure from above to cause said metal sheet to slide on said inclined-plane surfaces.
  • a supporting and retaining block 1 provided with a base 2 which is designed to rest on a purlin (not shown) and has two raised portions 3 and 4. Each raised portion partly delimits a respective external recess 5 and 6, which in turn is adjacent to a respective seat or cradle 7 and 8.
  • the raised portions 3 and 4 mutually diverge in an upward direction and terminate with an expansion at the top thereof, thereby delimiting an external shoulder or tooth 9.
  • the cradles 7 and 8 are instead inclined toward the adjacent raised portion 3 and 4 and their access inlet 10 is delimited, on one side, by an abutment tooth 11 which is proximal to the raised portion 3 and 4 and by a protruding step 12 on the other side.
  • the cradles 7 and 8 are preferably symmetrical with respect to a median vertical plane and extend at an angle of approximately 20° to 40° with respect to the base 2.
  • the step 12 is flanked by two lateral shoulders 13 and 14 which delimit two adjacent inclined plane surfaces 15 and 16.
  • the surfaces 15 protrude with the same angle of orientation as the underlying cradle 7 or 8 and are fillet through a short horizontal portion 17 with a side wall 18 of the base 2.
  • two slots 23 are formed, below which there is a respective countersink guiding portion 24 for a hole 25 passing through the base 2 to accommodate fixing screws for securing the block 1 to the purlin.
  • the end of the raised portion 4 is formed with two notches 26 which are coaxial with the slots 23 to allow free passage for a screwdriver for fixing the screws.
  • the base 2 of the block 1 has a plurality of longitudinal ribs 27 which are distributed inside a central lightening space 28 and in two lateral spaces 29 and 30 delimited by transverse partitions 31 protruding from said base surface 2 and co-planar with the peripheral rim of the base 2.
  • a metal sheet 33 which comprises an intermediate flat portion or body 34 which is formed preferably with transverse stiffening corrugations 35 and has folded longitudinal edges 36 and 37. More particularly, at each folded edge 36 there is (in the direction from inside outward) a rising portion 38, followed by a flat strip 39 and a slightly rising portion 40. From the rising portion 40 an inclined portion 41 extends downwards approximately at 90° with respect to both its uphill portion 40 and its downhill portion 42 and delimits, together with a successive flat portion 43, a deep inwardly extending fold 44.
  • the flat portion 43 is connected in turn to a slightly arcuate portion 45 which ends at a groove 48, the other edge of which extends into a rising flat portion 50 which belongs to a sharp upward fold 51 which has, on the opposite side, a sloping portion 52.
  • Said sloping portion is folded at 53 and terminates with an end portion 54, so as to delimit a channel for collecting and discharging any water that may have penetrated the joint into a gutter, as is known in the art.
  • the folded top 51 of the flat portion 50 is instead folded and extends cantileverwise outwards to a corrugated end portion 55 which is further folded in relief at 56.
  • the upper folded end 51 of the flat portion 50 at the edge 37 is lacking the raised portion 56.
  • a roofing according to the present invention To install a roofing according to the present invention, first of all multiple blocks 1 are fixed to the purlins, preferably at modular distances, by means of screws or the like which can be inserted in the holes 25. A folded portion 44 of an edge 36 ( Figures 7 to 9) of a metal sheet 33 is then moved closer and positioned in front of its respective cradle 7 of the various underlying blocks 1. At this point the operator inserts the folded portion 44 of the edge 36 into the cradle 7 of each blocks, e.g.
  • the concave part of the step 41 of the metal sheet 1 mates with the step 12 of the block 1, so that the flat strip 39 rests in the end on the corresponding horizontal portion 17 of the block 1.
  • edge 37 of the subsequent adjacent metal sheet is then placed on the edge 36 of the metal sheet already installed, by repeating the same operations described above so that the edge 37 mates with the end corrugated portion 51 and the block 1, while sliding along the inclined-plane sides 1b.
  • These operations too, can be performed in a simple manner by taking advantage only of pressure that the operator can apply with his feet.
  • a hermetic overlap joint is thus obtained which can withstand even extremely large lifting forces, e.g. due to the wind.
  • the blocks 1 are preferably made of antifriction material, which assists in preventing sliding movements of the metal sheets once installed.
  • the antifriction material can be of reinforced polyamide type, which is also a good insulator capable of ensuring good protection against stray electric currents, thereby also hindering electrolytic corrosion processes.
  • the metal sheets 1 can be made of copper, aluminum or stainless steel according to requirements.
  • a roofing obtained as described above ensures positive waterproofing and excellent drainage to the gutter owing to the presence of the channel 53, if provided.
