Description

Field of invention

[0001] The invention relates to the roofs of buildings.

[0002] It relates more particularly to a universal gutter for the flow of rainwater at the periphery of a roof structure, integrated into a sloping section of a roof. State of the art

[0003] It is common to incorporate roof structures of various shapes and functions into pitched roofs.

[0004] These roof structures include skylights and dormer windows.

[0005] In skylights or skylights, a rectangular frame is inserted into the roof slope and contains a tilting opening, incorporating glazing.

[0006] In dormer windows of the dormer type, two side cheeks of the dormer are fixed to the roof frame. The two cheeks are connected by the window frame and the assembly of cheeks and frame is topped with a waterproof covering connected to the roof.

[0007] Waterproofing the periphery of skylights and dormer windows is a major challenge in roof construction. Achieving good waterproofing requires optimal rainwater drainage around these roof structures, preventing water from entering the building. To this end, these roof structures are surrounded by gutters that are inserted under the roof covering elements (tiles, slates, etc.) and serve to collect water around the roof structure and channel it down the roof. The profile of the gutters must be adapted to the profile and dimensions of the roof covering elements (slates, tiles, waterproof sheets). The very wide variety of roofing elements available on the market (flat slates, tiles with various profiles, rigid flat or corrugated sheets, flexible membranes) means that a wide variety of gutters is required.This constraint considerably complicates the construction of roofs and increases their cost. It has a negative impact on the mechanical strength of the materials. Summary of the invention

[0008] The invention aims to remedy the aforementioned disadvantages of sloping roofs, incorporating roof windows, dormers, dormers or similar structures such as canopies or chimneys for example.

[0009] The invention has the particular objective of providing a gutter for equipping roof windows, skylights or similar structures, which is of simple design and whose construction is easy and inexpensive.

[0010] The invention aims specifically to provide a gutter which is universal, in the sense that it can be easily adapted to the majority of roof covering elements.

[0011] The invention also relates to a newly designed sloping roof incorporating a roof window, dormer window, dormer or similar structure.

[0012] Accordingly, the invention relates to a universal gutter for the flow of rainwater at the periphery of a roof structure, integrated into a sloping section of a roof, said gutter comprising a pair of longitudinal plates, an upper transverse plate and a lower transverse plate, said longitudinal plates and the upper transverse plate being designed to be inserted under covering elements of the roof section and the lower transverse plate being designed to overhang covering elements of the roof section; according to the invention, the gutter is characterized in that the longitudinal plates comprise, on the upper face, a succession of longitudinal grooves which extend over the entire length of the plates and in which longitudinal ribs are inserted. Detailed description of the invention

[0013] The invention applies to roofs which comprise a sloping slope and which incorporate a roof structure into said sloping slope.

[0014] In the remainder of this document, the term "roof structure" generally refers to any type of roof window, skylight, skylight, dormer window, dormer window or any other construction element that is commonly incorporated into a sloping section of a roof, for example a chimney, a turret or a dovecote (example, non-exhaustive list). The connection of the roof structure with the roof section may include straight edges or curved edges. Straight edges are preferred. Polyhedral connections are preferred. Among these, parallelepiped connections are preferred, for example square, rectangular and trapezoidal connections.

[0015] The gutter according to the invention is intended to be arranged around the roof structure, so as to channel rainwater around it and down the sloping slope of the roof, preventing water infiltration under the roof. For this purpose, it comprises a pair of longitudinal plates, an upper transverse plate and a lower transverse plate. In the remainder of this memorandum, the term

[0016] "longitudinal" means the direction of the slope of the sloping roof face and "transverse" means a direction transverse to said longitudinal direction. By definition, longitudinal plates and transverse plates are defined by the position they occupy when the gutter is normally arranged around the roof structure, in the sloping roof face. The longitudinal plates are then directed in the direction of the slope of the sloping roof face and the transverse plates are directed transverse to the slope. The length of the longitudinal plates is then their dimension in the direction of the roof slope. The upper transverse plate is, by definition, at a higher level than the lower transverse plate.

[0017] The gutter's longitudinal plates and the upper transverse plate are designed to fit under the roofing elements of the roof slope. They are normally placed on the roof frame, between it and the roofing elements, and are in direct contact with the roofing elements. The lower transverse plate is designed to overhang a row of roofing elements.

[0018] The roofing elements may be any roofing elements commonly used in the building industry, such as rows of natural or synthetic tiles or slates, a rigid metal plate (e.g. lead or zinc), a rigid corrugated sheet (e.g. rigid polyvinyl chloride, metal or cement reinforced with a fibrous material) or a flexible waterproof sheet (e.g. a synthetic polymer sheet, a bitumen sheet or a flexible metal sheet) (example, non-limiting list).

[0019] The longitudinal plates and the transverse plates of the gutter according to the invention may be flat or corrugated. It is preferred that the plates are flat.

[0020] In the gutter according to the invention, the longitudinal plates and the transverse plates are normally made of a waterproof material, capable of withstanding the usual atmospheric conditions, during normal use of the gutter on the roof of a building. For this purpose, they can for example be made of metal (for example lead, zinc, galvanized steel, copper) or a synthetic polymer and be obtained by rolling, molding or extrusion (example, non-limiting list). Synthetic polymers are preferred. The choice of polymer is not critical for the definition of the invention. It can be a rigid, semi-rigid or flexible polymer. It is advantageously an elastomer, possibly reinforced.Natural or synthetic mineral materials are well suited as elastomer reinforcement materials, especially fibrous fillers (e.g. glass fibers and rock wool), mineral aggregates and metal wires and powders.

[0021] According to the invention, the longitudinal plates comprise, on their upper face, a succession of longitudinal grooves, which extend over the entire length of the plates and longitudinal ribs are inserted into the grooves.

[0022] By definition, the upper face of the plates is the one that is directed upwards, when the gutter is normally arranged around the roof structure, in the sloping roof slope. The lower face is the face that is normally directed downwards.

[0023] In the gutter according to the invention, the ribs are retained laterally in the grooves. They are generally fitted into the grooves and then have, in the area of ​​their insertion into a groove, a profile complementary to that of the groove. This may be a square, rectangular or semi-circular profile (example list, not exhaustive). A trapezoidal dovetail profile is preferred.

[0024] The ribs are preferably removable.

[0025] The ribs normally run the entire length of the longitudinal plates and their function is to retain water laterally on the plate, preventing it from passing into the attic space under the roof. They can be made of the same material as the longitudinal plates or a different material. They are preferably rigid, semi-rigid or flexible.

[0026] The choice of rib height depends on the roof covering elements, so that they fit under them. In the case of corrugated roofing elements, the ideal ribs are those whose height is approximately equal to the amplitude of these corrugated roofing elements. With this type of corrugated roofing, the longitudinal plates of the gutter and the ribs they carry form high-flow gutters for the flow of rainwater.

[0027] In a preferred embodiment of the invention, the height of the ribs is adjustable, so as to be able to adapt them to the different models of roof covering elements, commercially available, such as the interlocking tile, the canal tile, the Roman tile, the purlin tile or the Flemish tile (https: / / toiture.pro / types-formes-tuiles.php) (exemplary, non-exhaustive list). To this end, the ribs can be provided with marks defining predefined heights, each height corresponding to a defined model of roof covering element. It is then sufficient to cut the ribs at the height corresponding to the selected covering elements, for example by means of cutting pliers. The aforementioned marks advantageously comprise rib breaking zones. These breaking zones can, for example, comprise longitudinal incisions, made in the ribs, allowing them to be broken precisely, for example by folding.The presence, on each rib, of a plurality of break zones, distributed at predefined intervals above the longitudinal plates of the gutter, reinforces the modular nature of the gutter by adapting it to a greater number of different roofing elements. It is recommended that a break zone be provided along the connection of the rib with the longitudinal plate, to allow the complete removal of the rib and thus adapt the gutter to essentially flat roofing elements.

[0028] In a particular embodiment of the invention, the ribs are flexible slats whose height can be adapted by compression under the weight of the roof covering elements.

[0029] In another embodiment of the invention, the longitudinal plates of the gutter comprise a succession of grooves on each of their two faces. Although this is not essential, it is advantageous for the grooves on the upper face of the plates to alternate with the grooves on the lower face of the plates. This alternating arrangement of the grooves makes it possible to reduce the thickness of the plates and gives them optimum flexibility, allowing, in particular, to bend them at right angles, without difficulty and without risk of breaking them.

[0030] In the gutter according to the invention, the upper transverse plate is designed to be inserted under a transverse row of roof covering elements. The lower transverse plate is intended to form a cantilever above a transverse row of roof covering elements. These two plates can be flat, corrugated or curved.

[0031] The gutter according to the invention is intended to serve as a watertight connection around a roof structure attached to an inclined roof plane. For this purpose, it is normally inserted between the roof covering elements and the framing slats, used to support these roof covering elements. It is specially designed for dormers, the term dormer designating, by definition, a window made in the roof of a building to provide daylight to the space under the roof (Le nouveau Petit Robert, Edition Dictionnaires Le Robert - Paris, June 2000, page 1469). In this document, in the absence of a more explicit definition, the term dormer designates indifferently a dormer window, a bull's eye window or a skylight type roof window (such as those marketed under the VELUX ®< brand and comprising glazing in the plane of a roof section) (example, non-limiting list).

[0032] As explained above, the longitudinal grooves of the longitudinal plates give them good flexibility. This flexibility facilitates their insertion into a corresponding groove in the roof structure. This groove in the roof structure may advantageously include a ventilation space provided between a load-bearing wall of the roof structure and cladding for the protection of this wall against the weather. In the case of a dormer window of the dormer window type, the wall and its cladding may be the cheeks of the dormer window.

[0033] The invention also relates to a roof comprising an inclined section, into which a roof structure is inserted, the sealing of the roof at the periphery of said roof structure being achieved by means of a gutter according to the invention. Brief description of the figures

[0034] Particularities and details of the invention will appear during the following description of the appended figures, which represent, schematically, some particular embodiments of the invention. There Figure 1 shows, in longitudinal section, a dormer window integrated into a sloping section of the roof of a residential house; The Figure 2 is a side view of the dog-sitting of the Figure 1 , associated with a gutter in accordance with the invention; The Figure 3 is a section along the vertical plane III-III of the Figure 2 ; There Figure 4 shows, on a large scale, a detail of the Figure 3 ; THE Figures 5 and 6 show details of two variants of the realization of the Figure 4 ; THE figures 7 to 10 are five views similar to that of the Figure 3 , showing the gutter according to the invention, adapted to five different types of roof covering elements; The Figure 11 shows the gutter of the Figure 4, associated with a sitting dog and a particular roof covering element; The Figure 12 shows, in perspective, a variant of the construction of the gutter of the Figure 4 ; and The Figure 13 shows, in perspective, another embodiment of the gutter according to the invention. The figures are not drawn to scale.

[0035] Generally, the same part numbers refer to the same items. Detailed description of particular embodiments

[0036] There Figure 1 schematically shows an inclined section 44 of a roof, in longitudinal section (section in a vertical plane, parallel to the slope of the roof). An opening 45 is made in the roof section and this opening is covered by a dormer designated as a whole by the reference notation 46. The dormer 46 is shown in detail in figures 2 And 3 . It comprises two triangular side cheeks 2 and 3 (only cheek 2 is visible at figures 1 And 2) fixed to two rafters 47 of the roof frame 44 and supporting an awning 4. The two cheeks 2 and 3 and the awning 4 are connected by a frame 7-7' of the dormer window 46. The cheeks 2 and 3 comprise, for example, panels 48 made of wood or polymeric material, covered with a layer 49 of thermal insulation on their inner face. The thermal insulation layer 49 is covered with a finishing layer (not shown), which is both decorative and protective. On their outer face, the panels 48 are protected from the weather by cladding 50 made of a suitable material, for example a metal plate, a rigid polymeric material plate or a cement plate reinforced with a fibrous material of the Eternit ®< (Etex) brand. Spacers 51 are interposed between the panels 48 and the cladding 50, so as to ensure ventilation.The 7-7' sleeper is a rectangular wooden frame, which rests on the roof frame by its lower transverse side 7' (. Figure 1 ). A wooden opening 8, carrying a glazing, is hinged in the frame 7-7'.

[0037] The seal between the dog-seat 46 and the roof covering elements 44 (tiles, slates, or similar elements) is obtained by means of a gutter 9 arranged at the periphery of the dog-seat 46. The gutter 9 serves to collect rainwater around the dog-seat and to evacuate it towards the bottom of the roof. The gutter 9 comprises a pair of longitudinal plates 10, along the cheeks 2 and 3 ( Figure 3 ), and a pair of transverse plates 26 and 40 ( Figure 2). The longitudinal plates 10 are placed on the purlin slats 52, along the cheeks 2 and 3 of the dog-seat 46 and they are partially covered by roof covering elements. They comprise a vertical longitudinal lip 36 which is engaged in a groove 55 between the panel 48 and the cladding 50, to achieve the sealing of the assembly. Similarly, the upper transverse plate 40 of the gutter 9 is placed on the purlin slats, under the roof covering elements. It has a lip 42 ( Figure 2 ), which is engaged behind a corresponding lip 41 of the rear transverse end of the dog-seat. The lower transverse plate 26 of the gutter 9 is placed on the purlin slats and comprises a lip (not visible in the figures) which is engaged behind a corresponding lip (not visible in the figures) on the lower side 7' of the frame. Its lower end 34 overlaps a row of roof covering elements.

[0038] The longitudinal plates 10 are substantially flat and carry three longitudinal ribs 11, 12 and 13.

[0039] The plates 10 are advantageously obtained by molding or extrusion of a synthetic polymer. It is preferred that the plates 10 are made of flexible or semi-rigid synthetic polymer.

[0040] The ribs 11, 12 and 13 are attached to the plates 10, as will be explained later. They are obtained by molding or extruding a flexible or semi-rigid synthetic polymer. The function of the ribs 11, 12, 13 will be explained later.

[0041] There Figure 4shows, on a larger scale, a particular embodiment of the longitudinal plates 10 of the gutter. These plates 10 comprise, on their upper face 37, a succession of grooves 32 and, on their lower face 38, a succession of grooves 33 (the expressions upper face and lower face being defined when the plate 10 is positioned on the roof slope). The grooves 32 and 33 extend over the entire length of the plate (the length being defined in the direction of the slope of the roof). The grooves 32 of the upper face of the plate 10 alternate with the grooves 33 of the lower face. This alternating arrangement of the grooves 32 and 33 makes it possible to reduce the thickness of the plate 10. The presence of the grooves 32 and 33 gives the plate 10 great flexibility, allowing it to be bent without difficulty, to form the vertical lip 36 defined above, with reference to the Figure 3 .

[0042] The grooves 32 and 33 are dovetailed. The plate 10 is held on the purlin slats 52 by means of tenons 43, inserted into the grooves 33 and fixed to the purlin slats 52 by screws 54.

[0043] The grooves 32 are used for the insertion of the ribs 11, 12 and 13 defined above with reference to the Figure 3 . To the Figure 4, only the rib 12 is shown. This is fitted into the groove 32 by its foot, profiled in a complementary dovetail. It comprises, along its height, four incisions 28, 29, 30 and 31. These incisions constitute breaking zones which allow it to be shortened to give it a predetermined height, in relation to a predefined type of roof covering element. The incision 31 is located at the intersection of the rib 12 with the plate 10. This incision 31 makes it possible to completely level the rib 12 and fill the groove 32. The ribs 11 and 13 may also comprise incisions similar to the incisions 28, 29, 30 and 31.

[0044] There Figure 5 shows a particular method of fixing a plate 10 to a purlin batten 52. In this particular method of fixing, a hook 58 is held in a notch of the plate 10 and fixed at its end to the tile batten 52 by means of a screw or a nail 59.

[0045] There Figure 6 shows an alternative embodiment of rib 12 of the Figure 4 . In this embodiment variant, the rib 11 comprises an alternation of hollow hexagonal chambers 60 and plates 62. The hollow hexagonal chambers 60 of the rib give it axial elasticity, which allows it to be shortened by compression. Notches 63, in the edge of the plates 62, are rupture zones similar to the incisions 28, 29, 30 of the Figure 4 , to shorten rib 12, if necessary.

[0046] There Figure 7 shows the sitting dog of the Figure 3 associated with a tile 15 of the Roman type. In this application of the gutter according to the invention, the ribs 12 and 13 of the longitudinal plates 10 have been shortened so as to fit under the tile 15, the latter bearing against the rib 11.

[0047] There figure 8 shows the sitting dog of the Figure 3associated with a flat interlocking tile 16. The tile 16 comprises, in a conventional manner, a flat part 17, one end of which has a bead 18 and the opposite end of which has a projecting edge 19. To adapt the dog-sitting to this type of tile, the rib 13 of the plates 10 has been completely leveled and the rib 12 has been shortened, so that the bead 18 of the tile 16 overlaps it exactly.

[0048] To the figure 9 , the sitting dog of the Figure 3 is associated with a corrugated tile 20 of the “Brabant truss” type. In this application, the three ribs 11, 12 and 13 have been shortened so that the tile rests exactly on the three ribs.

[0049] To the Figure 10 , the sitting dog of the Figure 3is associated with a covering element formed from a rigid flat plate 21, for example a natural or synthetic slate. In this application, the three ribs 11, 12 and 13 have been greatly shortened, so as to retain only a height of a few mm above the plate 10. They are covered with the slate 21. The small gap under the slates ensures good ventilation and the flow of rainwater.

[0050] In the embodiment of the Figure 11, the roof covering elements comprise large flexible sheets 23. These may for example comprise bitumen sheets (known under the trade term "roofing" and sold in the form of rolls), zinc sheets or sheets of flexible synthetic polymer (for example sheets of polyvinyl chloride or EPDM elastomer). The plates 10 do not have a rib. They are curved to form the vertical lip 36 which is slid between the panel 48 and the cladding 50 of the sitting dog. The flexible sheet 23 is placed on the plate 10 and rises along its lip 36. A tab 53 embedded in a groove 32 of the lip 36 holds the sheet 23 against it.

[0051] In the case where the dog-seat requires large gutters, it may be necessary to make the longitudinal plates and / or the transverse plates in several juxtaposed sections. This arrangement may be justified to avoid deformation of these plates by expansion, under the effect of strong summer heat. Figure 12 shows a junction element, specially designed to create a junction which is both watertight and capable of compensating for expansion of two successive sections of plates.

[0052] there Figure 12 , the plate 12 is designed to be attached to a similar plate. For this purpose, the end of the longitudinal plate 10 and that of its vertical lip 36 are leveled over a fraction 70 (71) of their length and half of their thickness. The second plate (not shown) which is attached to it has leveled areas complementary to the areas 70 and 71.

[0053] There Figure 13shows an angular piece, used to connect the lower transverse plate 26 or upper 40 of the gutter to a longitudinal plate 10 of the figure

[0054] 11. This angular part comprises two elements 64 and 65 connected at right angles. The element 64 comprises a longitudinal part 66 and a vertical part 67, perpendicular to the part 66. The parts 66 and 67 are arranged respectively in the extension of the longitudinal plate (10) and its vertical lip 36 ( Figure 11 ). Similarly, the element 65 comprises a transverse part 68 and a vertical part 69, perpendicular to the part 68. The parts 68 and 69 are arranged in the extension of the lower transverse plate 26 or upper 40. The ends 70 and 71 of the elements 65 and 66 are leveled, as explained above, with reference to the Figure 12 .
