Definitions

  • the sheets can be drilled in advance at the locations provided for the passage of the rods. This process is relatively expensive. For thin sheets, one can simply perforate them on site by driving in at the request of the fixing rods.
  • the installation process is then as follows: the rods are rigidly fixed in advance on the roof.
  • the sheets are placed one after the other on the roof, making them rest by the bottom of their ribs on the end of the rods.
  • the sheets are, in a way, successively "impaled” on these rods, then fixed by screwing a nut.
  • the object of the present invention is a method which, thanks to the use of an appropriate device, also object of the invention, avoids the drawbacks of drilling by impaling.
  • the device consists of protective end caps for the rods.
  • These end pieces are substantially cylindrical end pieces, tubular or at least hollow at one end.
  • the axial orifice of the end pieces has an internal diameter equal to that of the rods, increased by a slight clearance, sufficient to allow their easy fitting on the end of the rods, then their removal for reuse.
  • the upper end of the end pieces preferably has a sharp shape.
  • Each end piece is preferably associated with a guide washer fixed in an elastic and removable manner to said end piece.
  • These washers can be, for example, plastic, metal or composite material.
  • the device for fixing the washers to the end pieces can be, for example, a flexible membrane or a set of radial lugs penetrating elastically into a complementary circular groove traced in the end pieces. A little strong axial pressure on the washer makes it slide axially on the nozzle and disengage from said nozzle.
  • the washers have a lateral surface substantially complementary to the inner lateral surface of the ribs of the sheet, or at least tangent to the lateral inner faces of said ribs.
  • each rod is in the axial plane of a rib.
  • the sheet is guided during its descent, by contact between the internal lateral faces of its ribs and the lateral surfaces of the washers.
  • the upper surface of the washers is preferably tangent to the surface of the bottom of the ribs when the washers being in their normal place, the sheet rests by the bottom of its ribs on the ends of the end fittings fitted on the rods.
  • the upper face of the washers can thus help to support the sheets when they are placed on the roof by resting on the end of the end pieces before impaling.
  • the sheet With a rubber mallet, or a hollow tube, the sheet is impaled on the fixing rods or, more precisely, on the end of the end pieces, according to the prior art.
  • the rods, protected by the protective caps, are not damaged.
  • the sheet is perforated exactly in the axis of the ribs, this with holes the diameter of which is that of the outside diameter, not of the rods, but of the end pieces.
  • the clearance between orifice and rod is thus equal to the difference between the outside diameter of the end pieces and the diameter of the rods.
  • the washer (2) has three radial pins (3) which come engage in a circular groove (4) of the tip (1) and thus make the washer (3) integral, resiliently and removable from the tip (1).
  • the end piece (1) is fitted onto the end of a rod (5) with a diameter of 8 mm, itself integral with a fault (6) of the frame.
  • the internal diameter d l of the end piece (1) is 8.2 mm, which allows it to be easily fitted onto the rod (5).
  • the outside diameter d 2 of the end piece is 10 mm. Its height is 16 mm.
  • the groove (4), traced at the upper 1/4 of the end piece (1) prevents it from fitting onto the rod (5) over a length of more than 12 mm. It can be noted that the end piece (1) is cut at the top in the form of a re-entrant dihedral, which gives it two diametrically opposite cutting edges (7-7 ').
  • the same elements can be distinguished after fitting a sheet (8) which rests by the bottom of a rib (9) (which is a part in elevation relative to the roof) on the upper ends of the end caps, here the edges (7-7 ').
  • the washers (2) have a shape of revolution whose lateral surface has a conical portion (10) which is tangent to the two lateral internal faces (11-11 ') of the rib (9) when the latter rests on the end. upper (7-7 ') of the end piece (1) disposed in the axial plane of the rib.
  • the upper surface (12) of the washer (2) is tangent to the lower surface of the bottom of the rib (9).
  • the washer (2) thus contributes somewhat to supporting the weight of the sheet (8) at the same time as the edges (7-7 ') of the end piece (1).
  • the sheet (8) is guided by the washers (2) whose conical lateral part (10) comes into contact with the lateral faces (11-11 ') of the ribs (9).
  • the axes (XX ') of the rods (5) are thus in the axial plane of the ribs (9).
  • the upper surface (12) of the washers (2) contributes to supporting the weight of the sheet (8).
  • the bottom of the ribs (9) is then perforated according to one of the known techniques, here by the action of a tube (12) exerting a force F in the axis of the rods (5), as shown in FIG. 3.
  • the end piece ( 1) and the tube (13) operate in the manner of a cookie cutter.
  • a disc (14) is easily cut in the bottom of the ribs (9) which are raised relative to the rest of the sheet (8).
  • the orifice (16) cut in the rib (9) has a diameter d 2 of 10 mm, equal to the outside diameter of the end piece (1).
  • the sheet (8) is then pushed back until it rests on the purlins (6) as shown in FIG. 4.
  • the washers (2) do not necessarily have a shape of revolution, but can also have, for example, horizontal sections of square, rectangular or hexagonal shape.
  • two lateral faces of the washer must be complementary to the lateral faces (11-11 ') of the rib (9).
  • the cover sheets must overlap laterally according to a rib.
  • a tip will also be used but, in this case, without its washer which, otherwise, would remain trapped between the two sheets.
  • the covering rib is then guided by the rib of the lower sheet, also by the other fixing rods of the upper sheet.
  • the sheet will be perforated by the other rods before perforation along the covering rib.
