Definitions

  • the invention relates to the roofs of buildings.
  • 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.
  • roof structures include skylights and dormer windows.
  • a rectangular frame is inserted into the roof slope and contains a tilting opening, incorporating glazing.
  • 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.
  • 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.
  • 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.
  • the invention is specifically aimed at providing a gutter which is universal, in the sense that it can be adapted easily to the majority of roof covering elements.
  • the invention also relates to a newly designed sloping roof incorporating a roof window, dormer window, dormer or similar structure.
  • 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;
  • 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.
  • the invention applies to roofs which comprise a sloping slope and which incorporate a roof structure into said sloping slope.
  • roof structure generally designates any type of roof window, skylight, fanlight, dormer window, dormer window or any other construction element which it It is common to incorporate into a sloping roof slope, for example, a chimney, a turret or a dovecote (list is exemplary, not exhaustive).
  • the connection of the roof structure with the roof slope can have 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.
  • 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.
  • it comprises a pair of longitudinal plates, an upper transverse plate and a lower transverse plate.
  • longitudinal means the direction of the slope of the sloping roof face and "transverse” means a direction transverse to said longitudinal direction.
  • 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.
  • 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.
  • 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).
  • 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
  • a flexible waterproof sheet e.g. a synthetic polymer sheet, a bitumen sheet or a flexible metal sheet
  • 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.
  • 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.
  • 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 (list exemplary, non-limiting).
  • 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 reinforcing material for the elastomer, especially fibrous fillers (for example glass fibers and rock wool, mineral aggregates and metal wires and powders.
  • 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.
  • 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.
  • 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.
  • the ribs are preferably removable.
  • the ribs normally extend along 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 under the roof. They can be made of the same material as the longitudinal plates or of a different material. They are preferably rigid, semi-rigid or flexible.
  • rib height depends on the roof covering elements, so that they fit under them.
  • the ideal ribs are those whose height is approximately equal to the amplitude of these corrugated roofing elements.
  • 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).
  • 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.
  • breaking zones can, for example, comprise longitudinal incisions, made in the ribs, allowing them to be broken precisely, by example by folding.
  • the ribs are flexible slats whose height can be adapted by compression under the weight of the roof covering elements.
  • the longitudinal plates of the gutter comprise a succession of grooves on each of their two faces.
  • 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.
  • 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 row cross-section of roof covering elements.
  • 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 (The new Petit Robert, Edition Dictionnaires Le Robert - Paris, June 2000, page 1469 ).
  • dormer window refers indifferently to 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).
  • 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.
  • the wall and its cladding may be the cheeks of the dormer window.
  • the invention also relates to a roof comprising an inclined section, into which a structure is inserted. roof, the waterproofing of the roof at the periphery of said roof structure being achieved by means of a gutter according to the invention.
  • FIG. 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.
  • 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 frame rectangular wooden beam, 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'.
  • the seal between the dog-seat 46 and the roof covering elements 44 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.
  • 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.
