Definitions

  • the present invention generally relates to the field of building construction and it relates more particularly to a method for producing a roof covering for a building.
  • the means of covering are fixed to resistant elements of the building such as a framework or a structural work, which requires being able to insert therein fixing devices of the type of screw, nail, or equivalent. This results in the tedious work of locating the location of the element, drilling the element, installing dowels if necessary and/or other actions.

  • the corrugated plates and the slats are fixed to an insulating material by special anchoring screws.
  • the screws pass through the insulation to attach themselves to more resistant "hard” construction materials, such as those of a frame or another construction structure (wood, metal, masonry, brick, sheet metal, etc.).
  • the insulating material which can be in plates or in rolls which are unrolled, is at least a thermal insulator.
  • the insulating material may optionally include other functions such as a vapor barrier, for example.
  • This insulating material is light, not very compact and has mechanical properties, in particular tear or tensile strength, which are much lower than those of other “hard” building materials.
  • the insulating material has a compressive strength at 10% deformation, ⁇ 10, as defined by standard EN 826, of at least 50 kPa.
  • the resistance properties of these insulating materials are more specifically described in standard EN 826: 2013 "Thermal insulating products intended for building applications - Determination of behavior in compression”.
  • the insulating material typically consists of plates of rock wool, expanded polystyrene (EPS), extruded expanded polystyrene foam (XPS), or polyurethane.
  • EPS expanded polystyrene
  • XPS extruded expanded polystyrene foam
  • polyurethane polyurethane
  • the usable insulators have sufficient weight and crushing strength and are therefore of suitable compactness which can possibly be differentiated according to the location on the roof, the geographical area of location of the building as well as the geometric conformation. slopes that make up the roof.
  • normal class buildings with little exposure to gusts of wind, urban buildings
  • median class buildings that can be exposed to gusts of wind, tall buildings that stand out in the urban context or buildings beyond/outside the urban context
  • high class buildings often exposed to gusts of wind, coastal areas, non-urban context, very tall buildings, etc.
  • the invention can be implemented with several types of insulation.
  • This material can be chosen with a high density p > 140 kg/m 3 and at single density, with a compressive strength ⁇ 10 ⁇ 50 kPa.
  • Stone wool for the middle class This material can be chosen with a high density p > 150 kg/m 3 and double density (210/145), with a compressive strength ⁇ 10 ⁇ 50 kPa.
  • EPS Extruded polystyrene
  • Extruded expanded polystyrene which, for all classes, has a compressive strength o10 > 150 kPa.
  • thermal insulation is used whose minimum resistance required for crushing at 10 years is ⁇ 10 ⁇ 50 kPa.
  • the anchor screws used here for fixing to the insulating material are specific and are similar to augers or "auger” and they therefore have a diameter of their thread or helix (these two terms being equivalent) very large compared to their diameter. shaft in order to have a large contact surface with the insulating material.
  • the anchor screws are made of plastic.
  • the slats are fixed via connecting pieces to the insulating material but also to the corrugated plates because the anchoring screws are screwed through the corrugated plates.
  • the building for which the roof is made comprises a roofing support which consists of a masonry shell made of hollow bricks 1 forming a flat surface which is continuous outside the equipment crossing areas (chimney, ventilation, etc.).
  • This roof support forms a slope and the roofing produced will also be sloped.
  • insulation plates 2 are rigid plates of expanded polystyrene.
  • insulation boards should be properly bonded/secured to the underlying structure by means suitable for the underlying structure and the boards.
  • the underlying structure and the boards For example, one can use dowels for an underlying brick and cement structure, screws for an underlying wooden structure, adhesive as in the example (avoid sticking with foams because they do not do not comply with European standards) for cement surfaces, wood, tiles, etc.
  • the layer of insulating material consisting of insulating plates 2 glued to the structural work of hollow bricks 1 forms an upper surface which is also flat and continuous and, figure 11 , we begin to install on this surface corrugated plates 3 of the first type, bituminous in cellulose fibers, starting towards the bottom of the slope.
  • These corrugated plates 3 comprise a repeating pattern consisting of a series of three corrugations separated from another series of three corrugations by an extended hollow 31 which is flat.
  • Each corrugation has a peak 30 bordered by two depressions 31 and these depressions 31 within a series of three corrugations are narrow and rounded compared to the extended and flat depression 31 separating the series.
  • the side edges of the corrugated plates overlap/overlap within a strip of corrugated plates just as for the overlay/the overlap of the end edges along the slope between corrugated plates of two successive strips along the slope, the end of the higher corrugated plate along the slope overlapping that of the lower of the two strips. That's what we see figure 12 for the ends of corrugated plates along the slope between two strips.
  • the corrugations are elongated/arranged in the direction of the slope in order to allow the flow of any water that may have found its way onto the corrugated plates.
  • anchoring screws 6 arranged along the superposition of the end edges of corrugated plates 3 and making it possible to fix each time two corrugated plates to the insulating plates 2. These anchoring screws 6 are screwed through the corrugated plates 3 at the tops 30 of the corrugations. It should be noted that for all types of corrugated sheets, the anchoring screws are preferably installed on the tops of the corrugations in order to guarantee optimum sealing against liquid water.
  • slats 4 are then installed in parallel lines perpendicular to the slope and whose spacing is adapted to the dimensions of the covering elements which are here tiles 5 which will cover the whole.
  • the slats 4 are therefore also perpendicular to the undulations.
  • the slats 4 are fixed to the insulating plates 2 and to the corrugated plates 3 by anchoring screws 6 via connecting pieces 7.
  • the anchor screw is installed lower in the direction of the slope relative to the slat.
  • the anchoring screw is installed higher in the direction of the slope relative to the slat and a connecting piece is used which makes it possible to retain the slat by its lateral face on the side opposite the screw in order to prevent the slat from escaping and sliding down the slope.
  • the tiles 5 which will be laid have lugs on their underside and the slats 4 allow the tiles 5 to be retained along the slope by their lugs.
  • a line of slats is implemented along the bottom of the slope in order to simply raise the tiles of the bottom row in relation to the corrugated sheets and to allow better ventilation between the corrugated sheets and the tiles and avoid that the bottom tile is applied directly to the corrugated plate at the bottom of the slope.
  • the connecting piece 7 encloses by its claw 73, 71, 74 partly the slat 4 passing through the top of the latter.
  • the connecting piece 7 is placed on a crest 30 of corrugation so that the anchor screw 6 is screwed through the crest 30 of the corrugation and into the layer of insulating material 2 which is below the corrugated plates 3.
  • the anchoring screws 6 used to fix the slats 4 via the connecting pieces therefore also serve to complete the fixing of the corrugated plates 3 to the insulating material. From this arrangement, it also follows that the slats 4, via the connecting pieces 7, are also fixed to the corrugated plates 3.
  • the anchor 7' with legs and even 7 without legs is relatively stable once placed on the lath and the top of the corrugation.
  • the anchor screw for the connecting piece will here be screwed through a superposition of two side edges of two corrugated plates of a row. At other locations along the slat 4, it may be a single corrugated plate which is crossed by the screwing of the anchor screw 6.
  • anchoring screws 6 are all screwed at the level of the vertices of the undulations of the corrugated plates and it is therefore possible to use anchoring screws of the same length without the need for anchoring screws of different lengths. If certain anchoring screws had been installed in corrugated hollows, then anchoring screws 6, 8 of different shaft lengths 61, 81 could have been provided for fixing in a hollow or flat (short anchoring screw) and for top fixing (long anchor screw).
  • An electric screwdriver 11 is implemented with a TORX ® screwdriver bit because the head 60, 80 of the anchoring screw 6, 8 has a driving recess 64, 84 for screwing (or even unscrewing) TORX ® .
  • anchor screws In practice, it is preferred to install the anchor screws at the crests of the corrugations and if anchor screws of different shaft lengths and/or different thread pitches and/or different and therefore different thread diameters are provided types of anchor screws, this is essentially a function of the height of the corrugations and/or the thickness and the nature of the insulating material which are used. Anchor screws can therefore be chosen mainly according to the characteristics of the corrugated plates, the location of the screw (hollow/flat or top) and the insulating material.
  • an anchor screw is used, the length of which is adapted to the height of the corrugations and to the thickness of the insulating material so that the anchor screw enters the insulating material well but does not cross it completely and does not does not come out on the other side of the insulating material.
  • the measuring meter is intended to position the slat 4 correctly with respect to a previous slat along the slope or with respect to the lower edge of the slope, depending on the dimensions of the tiles.
  • the bottom tiles must have their lower edges above the gutter 10 arranged at the edge of the roof.
  • the tiles 5 can be installed on the slats starting with the bottom row as seen figure 15 .
  • anchor screws are used first, before the installation of the slats, to fix the corrugated sheets to the insulating material, and other anchor screws are used secondly to fix the slats , in particular via connecting pieces, to the corrugated plates and, preferably, also to the insulating material.
  • This first use of the anchor screws can be carried out to ensure optimal fixing of the corrugated sheets or only to ensure a minimal fixing, less than the optimal fixing, during the realization of the roofing, the second use of the anchor screws allowing to achieve the optimum fixing of the corrugated sheets.
  • the optimum fixing corresponds to a degree of fixing which allows the roof to resist tearing or destruction, in particular due to the wind, with regard more particularly to corrugated sheets.
  • the fastening of the corrugated sheets should preferably be optimal. It should be noted that the weight and type of roofing elements can also influence the degree of fixing since these elements apply a certain weight to the slats and corrugated sheets.
  • bituminous corrugated plates made of cellulose fibers having other corrugation patterns and for example with regular corrugations (not separated by flats) or not, in particular the one 3" from the figure 7 which we will present later in more detail.
  • the figures 1 to 4 represent a single connecting piece 7 (without side legs) intended to be installed to press the slat 4 against the corrugated plate 3, 3', 3" and making it possible to fix the slat 4 to the corrugated plate 3, 3', 3" and the insulating material 2.
  • the connecting piece 7 is formed of several parts: a plate 70 and a retaining claw 71, 73, 74 of the slat. We will see in relation to the figures 16 to 18 that it is also possible to implement connecting pieces 7' further comprising two lateral tabs 72.
  • the connecting piece 7, 7' is metallic.
  • the plate 70 which is flat and here square in shape is intended to be placed flat on a corrugation top 30 of the corrugated plate 3, 3', 3", the connecting piece 7, 7' being installed on a top
  • a crossing hole 78 is made in the center of the plate 70 in order to allow the passage of an anchor screw shaft 6, 8 without the thread of the screw having to force or widen the passage orifice 78 when screwing in the anchor screw but, preferably, preventing the screw from being extracted through the passage orifice 78 by simple axial traction.
  • the passage orifice 78 has a diameter equal to approximately 3/4 of the width of the thread 62, 82 of the anchor screw, this to allow a better mesh between the anchor screw and the plate 70. A greater coupling between the anchor screw and the plate 70 is thus implemented to take account of the mechanical properties of the insulation.
  • the retaining claw 73, 71, 74 of the slat is continuous with one side of the plate 70 which is in relation with the top 30 of the corrugation.
  • the retaining claw 73, 71, 74 which is in several portions at least partially encloses the slat 4 and, in this example, encloses its upper face by a portion 71, one of the two side faces over its entire height by a portion 73 and the other side face over part of its height by a portion 74.

  • the inclination of the lateral legs with respect to the plate 70 is adapted to the shape and dimensions of the undulations: on the figure 16 and 17 , the side tabs 72 of the connecting piece 7' are vertical and perpendicular to the plate 70, figure 18 the side tabs 72 of the connecting piece 7' gradually move apart from one another going downwards.
  • the inclination of the side tabs 72 can be adjusted by forcing or twisting the metal of the connecting piece 7'.
  • ribs 77 obtained in particular by stamping. These ribs can also be made on the connecting pieces 7' with side tabs 72.
  • the connecting piece 7, 7' is made of metal, for example stainless steel, galvanized steel, and is obtained by cutting a blank from a metal plate and this blank is then bent to form the different parts: plate 70 , claw 73, 71, 74 for retaining the slat and any lugs 72.
  • the metal thickness is between 1 mm and 1.5 mm and is preferably 1.2 mm. Since the slats 4 generally have standardized dimensions, it is possible to provide for the production of two models of connecting pieces allowing adaptation to most of the dimensions encountered for slats and which are 3x3 cm, 3x2 cm and 3x4 cm.
  • a hole 79 has been provided through the portion 71 of the claw of the connecting piece 7 on the figure 1 to 4 .
  • the hole 79 is omitted.
  • the hole 79 can also be made on the connecting pieces 7' with side tabs 72.
  • part of the portion 71 of the claw and it is bent downwards and it serves as a point for nailing the claw to the slat: the installer places the claw on the slat and strikes the claw with a mallet so that the point of the V sinks into the latte.
  • corrugated plates differ in particular by the presence or not of flats and the number of undulations/waves between two flats.
  • the corrugated plate 3 of the first type of the figure 6 or the figure 17 comprises series of three undulations and a flat hollow, each undulation being of a width allowing the use of a connecting piece 7′ with vertical tabs 72 in the event that they are implemented.
  • the 3' corrugated plate of the second type of the figure 5 or the figure 18 has series of two undulations separated by a flat hollow.
  • Each corrugation of the corrugated plate 3' being wider than that of the corrugated plate of the first type 3, a connecting piece 7' with lateral tabs 72 inclined with respect to the vertical is then used if connecting pieces 7' with tab sides are used.
  • the 3" corrugated plate of the third type of the figure 7 has regular waves and does not have a flat.

  • anchor screws of the same length for the fixings in the depressions/flats and for the fixings at the tops of the corrugations.
