FR2855199A1 - Rainwater guttering manufacturing procedure has flat base and raised side formed by shaping a metal strip with rollers - Google Patents

Abstract

The procedure for making rainwater guttering for sloping tiled roofs where the guttering has a flat base fastened to the roof surface close to its lower edge. e.g. under a row of tiles, and a raised outer surface to retain and guide the rainwater, uses a profiling machine with rollers to make a fold (13) between the base and raised surface in a continuous strip of metal such as aluminum, copper or zinc. the procedure also includes a stage that gives the guttering's raised surface finishing folds (14).

Description

Method of manufacturing a non-hanging gutter, non-gutter

  pendant, manufacturing device and vehicle equipped with the corresponding device.

  The field of the invention is that of building. More specifically, the invention relates to non-hanging gutters and the corresponding manufacturing and installation techniques.

  Traditionally, there are two categories of gutters: - pendant gutters or cornice gutters, hung on the walls of a house or building, and directly below a roof descent; - non-hanging gutters, designated in certain regions by Nantes gutters or Le Havre gutters, hung on the slope of roofs, in the vicinity of the edge thereof. The invention relates exclusively to this second category of 15 gutters, said to be from Nantes or Le Havre.

  Currently, installers of Nantes or Le Havre gutters use industrial manufacturers of gutters who supply these in elements of 2 to 3 meters, generally zinc and possibly copper.

  The installer must therefore assemble the elements edge to edge, making 20 welds.

  It is therefore understood that the installer is required to carry out a very large number of welds and of course depends on the dimensions of the dwelling or building considered.

  These operations prove to be tedious and obviously tend to considerably increase the installation times.

  In addition, the welds oxidize over time, and considerably deteriorate the gutters, which then requires a new intervention by a professional.

  The object of the invention is in particular to overcome the drawbacks of the prior art.

  More specifically, the object of the invention is to propose a new technique for manufacturing non-hanging gutters which makes it possible to envisage significant time savings concerning their installation.

  The invention also aims to provide a gutter 5 corresponding to this technique which is more reliable and more durable than that obtained with traditional techniques.

  The invention also aims to provide such a gutter and such a technique which are simple in design and easy to implement.

  These objectives, as well as others which will appear subsequently, are achieved by virtue of the invention which aims at a method of manufacturing a non-hanging gutter comprising a substantially flat gutter bottom and intended to bear on a slope roof, and at least one rim for retaining and guiding rainwater, characterized in that said bottom and said rim are produced on either side of at least one transition fold formed in a metal strip 15 by a profiling technique.

  Thanks to the invention, the method makes it possible to produce gutters having lengths corresponding directly to the dimensions of the roof on which they are intended to be installed.

  The profiling technique therefore makes it possible to manufacture these gutters in possibly long lengths, which avoids, or at the very least considerably limits the need for numerous welds (as is the case with gutters made of elements of constant length and limited).

  Consequently, the installation times are considerably reduced, and the installation is carried out more comfortably for the installer (the latter performing less tedious operations linked to the fittings).

  Advantageously, the manufacturing process comprises at least one step of forming at least one finishing ply.

  In this case, said complementary step or steps are preferably carried out in continuity with the step of forming said one or more plies.

  The profiling of the gutter is in other words obtained overall in a single operation, and therefore results in the production of a gutter ready to be mounted.

  The invention also relates to a non-hanging gutter comprising a substantially flat gutter bottom and intended to bear on a roof slope, and at least one rim for retaining and guiding rainwater, characterized in that said bottom and said flange are produced on either side of at least one transition ply formed in a metal strip by a profiling technique.

  Such a gutter therefore appears more reliable and more resistant than conventional pendant gutters.

  Indeed, the non-hanging gutters of the prior art are obtained by connecting a greater or lesser number of elements.

  Each connection is made to deteriorate, more or less rapidly, depending on the care taken in its production.

  On the other hand, a gutter according to the invention is in one piece, whatever its length. Only corner connections are made, usually by cold welding.

  Preferably, the gutter comprises at least one finishing fold.

  These folds, depending on their shape and their location on the gutter, give the latter satisfactory qualities both functionally and aesthetically.

  According to an advantageous solution, the gutter is made from at least one of the materials belonging to the following group: 25 - aluminum; - zinc; - copper.

  The invention also relates to a device for manufacturing a non-hanging gutter, comprising a plurality of rollers and profiling rollers intended to form, on a metal strip, at least said bottom and said edge of said gutter.

  Preferably, said rollers and said rollers are provided to also form on said strip said finishing folds.

  The invention also relates to a vehicle equipped with a device for manufacturing a non-hanging gutter, characterized in that said device comprises a plurality of rollers and profiling rollers intended to form, on a metal strip, at least said bottom and said edge of said gutter.

  Other characteristics and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment of the invention, given by way of illustrative and nonlimiting example, and the appended drawings among which : - Figure 1 is a side sectional view of a non-hanging gutter mounted on a building or residential roof; - Figures 2 and 3 are side sectional views of a non-hanging gutter, Figure 2 being an enlarged partial view of Figure 3; - Figure 4 is a perspective view of a non-hanging gutter according to the invention; - Figure 5 is a perspective view of a device for manufacturing a non-hanging gutter according to the invention.

  With reference to FIG. 1, a non-hanging gutter comprises a bottom 11 and a ledge 12 intended to collect and guide the rainwater which flows from the slope of a roof, the bottom 11 and the ledge 12 extending on either side of a fold 13.

  A gutter of this type is placed under a row of tiles 2, placed on a double layer 3 and fixed to the roof using hooks 4.

  Of course, other accessories are useful for the installation of such gutters, and in particular births, water downspouts, corner pieces ...

  It is specified that the doubling is obtained using a manual extruder, in sections of 2 m or 3 m, this doubling being lacquered in the same color as that used to lacquer the gutter and the hooks.

  As illustrated in FIGS. 2 to 4, the gutter according to the present embodiment also has finishing folds 14 giving certain qualities to the gutter such as qualities of rigidity, aesthetics and safety when it is put in place. place (especially avoiding the protruding edges).

  As an indication, the illustrated gutter has the following dimensions a: 10mm b: 0.8 mm 10 c: 15 mm d: 5 mm e: 28 mm f: 4 mm g: 4 mm h: 79.6mm i: 82, 80 mm d: 27 mm k: 1.5 mm 1: 154 mm 20 m: 165 mm n: 2 mm o: 1 mm d: 91 mm o: 46 A gutter of this type can be produced according to the dimensions below. above, from strips with widths of 300 mm, 350 mm or 400 mm.

  According to a particular embodiment, such a gutter is produced from an aluminum strip (but could similarly be produced from zinc or copper according to other possible embodiments).

  According to the invention, this non-hanging gutter is obtained by a profiling technique using a device such as a roll forming machine 5 as illustrated in FIG. 5.

  This type of profiling machine 5 implements a plurality of rollers 51, 52, 54 and 5 of rollers 52 driven in rotation by a geared motor 56 so as to conform a strip 6 introduced at one end of the profiling machine.

  As an indication, the strip 6 undergoes the following steps: - the rollers 51 of the roll forming machine fold 180 the edges of the strip: - the rollers 52 and the rollers 53 conform the folds (or curvatures) of the flange 12; the rollers 54 deform the strip 6 so as to form the fold 13.

  These steps are therefore carried out continuously, successively. This profiling machine makes it possible, for example, to produce non-hanging gutters having lengths up to 27 meters or more.

  Such a roll forming machine operates using a conventional 220 V power supply and has a footprint of 2400 mm (length) x 620 mm (height) x 650 mm (width), for a weight of the order of 480 kg. .

  This profiling machine is advantageously mounted and fixed to the floor of a van type vehicle, fitted out in a workshop.

  Inside this vehicle, provision is made: - upstream of the roll forming machine, a metal strip roll mounted on a reel; - downstream, a manual guillotine using which the gutter is cut to the desired length.
