Definitions

  • the invention relates to a base for supporting a roof opening structure, in particular a base for a smoke outlet.
  • the invention will be more particularly described as regards a base for a smoke outlet without however being limited thereto.
  • the base can be used for skylights for example.
  • the base is intended to surround any roof opening and serve as a support in various uses for a structure closing off the roof opening, the structure being openable depending on the uses.
  • the term "roof opening” means a roof opening which is closed off by an attached structure, the structure being able to be closed in a fixed or openable manner.
  • the arrangement of a smoke outlet on the roof of a building consists in making an opening in the roof covering, placing a base therein which forms a frame delimiting the perimeter of the roof opening, and fixing on the base the frame or frame of the outlet.
  • the base makes it possible to adapt to the type of roof covering, the covering being able in particular to be flat or to be profiled, for example of the corrugated type (for corrugated sheet or fiber cement roofing) or of the trapezoidal profile type (for steel deck covers).
  • the base thus comprises an application surface intended to be in a horizontal plane and having a surface whose profile is adapted to that of the covering of the roof, and an inner peripheral wall which delimits the smoke exhaust opening for the outlet.
  • the peripheral wall rises in a plane perpendicular with respect to the applied surface to support the frame of the outlet.
  • the bases are commonly made from a plastic material, such as polyester reinforced with fiberglass. Manufacturing by plastic molding makes it easy to offer different seating surface profiles. However, the outlets have different dimensions which are related to their smoke extraction capacity depending in particular on the volume of the building, the type of building, and the activity for which the building is used. Manufacturers usually offer at least five models of standard sizes. It is therefore necessary to provide one mold per type of roof and per outlet dimensions, which is ultimately relatively expensive.
  • the manufacturing process requires, after molding, the addition of fiberglass cloth on the molded polyester part. However, this stage of the process is still carried out in an artisanal manner. The layers of fiberglass fabric are deposited and glued manually, requiring installation and drying times which do not contribute to a reduction in manufacturing costs, nor to an increase in the production yield of the bases.
  • the object of the invention is therefore to obviate the aforementioned drawbacks, by proposing a roof opening structure support base, in particular a smoke outlet base, which takes up little space before installation and can be easily handled, while meeting the various dimensional requirements of the market, and being simplified and less expensive to manufacture.
  • the support base for a roof opening structure in particular a support base for a smoke outlet or a support base for a roof opening frame, is in accordance with claim 1.
  • the base comprises an overlay surface and a peripheral wall (on the edge of the overlay surface) which delimits an opening (corresponding substantially to the roof opening) and forms a frame, the peripheral wall extending in a plane substantially perpendicular to the applied surface, the base being in several parts.
  • the base is not one-piece. In several pieces (or parts), it can be stored by reducing the storage surface; in particular, the volume required for transport is reduced by ten. In Furthermore, the base is less bulky and less heavy, and can be handled easily and by a single person who will handle each part independently. Installation on a roof is also simplified due to the reduced size of the parts to be handled. The stacking of parts is also facilitated.
  • the multi-part design provides parts with dimensions that are much smaller than those of a one-piece base, which allows parts to be manufactured in plastics material according to a manufacturing process by thermoforming, making the manufacturing process totally industrial.
  • the molds for thermoforming also have a lifespan of several thousand parts, compared to a hundred for the molds of one-piece bases in fiber-reinforced polyester. This makes it possible to significantly reduce manufacturing costs and increase production yield.
  • the base is modular, in particular the base is modular according to its largest dimension (according to its length). Indeed, by being in several parts, it is possible to adapt to all dimensions of the base, either via parts whose length can vary which generates a variation at least in the length of the base, or via parts the appropriate arrangement of which with respect to the other parts of the base makes it possible to vary the dimensions of the base.
  • the base comprises end pieces corresponding to the ends of the base and connecting pieces having the function of connecting the end pieces and the extension function. Consequently, it is no longer necessary to manufacture a base by type of dimensions, but to manufacture a series of so-called end pieces which correspond to the geometry of the ends of the base and to the desired dimensions (in particular as regards the width of the base), and so-called connecting parts which constitute extensions for adapting (in particular increasing) the dimension of the base in one direction (in particular its length).
  • the invention makes it possible to obtain several base lengths.
  • the base of the invention makes it possible to adapt to roof openings which are not necessarily standard, in particular in the renovation, the extensions will be made to the desired dimensions.
  • the two end pieces are identical.
  • the two end pieces each have a generally U-shaped view from above.
  • the two connecting pieces are identical.
  • each of the connecting pieces has a linear shape in top view.
  • the base comprises two end pieces of the same shape and the same dimensions, and two identical connecting pieces which are assembled to the two end pieces and connect the two end pieces, in particular the two end pieces have a generally U-shaped top view while the connecting pieces have a linear shape and each connect the two flanges of the respective U's of the end pieces.
  • the opening of the base has a general square or rectangle shape, each of the end pieces having a general U shape forming two opposite sides and part of the two other opposite sides, while each of the connecting pieces connecting the two end pieces form the remaining part of said two other opposite sides.
  • each part comprises a bearing surface and a peripheral wall, which provide, by assembling the parts, respectively the entire bearing surface of the base and the entirety of its peripheral wall.
  • each part comprises an application surface which has a profile adapted to match the profile of a roof covering for which the base is intended.
  • the end pieces between them (when there are no connecting pieces) or the connecting pieces assembled to the end pieces are assembled by overlapping and in particular by mutual cooperation.
  • the end pieces or the connecting pieces are assembled by overlapping adjacent pieces, in particular each of the end and connecting pieces has, in particular at their surface of application, male shapes on one side and shapes negative female shapes on the opposite face, said female shapes of the part overlapping the adjacent parts being able to match the male shapes of the adjacent parts.
  • each end and connecting piece comprises a peripheral wall which has on one side male shapes and female shapes with their negative on the opposite side, the male and female shapes of a piece cooperating by mutual engagement with respectively the female and male forms of an adjacent part in the areas of overlap of a part on the adjacent part.
  • the male and female shapes and their cooperation for the application of an end piece on another end piece, or a connecting piece on two opposite end pieces, provides an intimate mechanical assembly without the need to bring back mechanical fixing means.
  • the male and female shapes are preferably in an alternating pattern and arranged at least on the upper part of the peripheral wall of the end and connecting parts, which increases the rigidity of the parts.
  • At least one part in particular at least the one intended to be upstream of the slope of a cover for which the base is intended, comprises a peripheral wall which has a slope inclined in the direction of the associated application surface.
  • each of the parts of the base is manufactured by thermoforming.
  • each of the parts is made of plastic material, optionally of composite plastic material.
  • each of the parts is based on ultraviolet-resistant plastic material, in particular is made of ABS-PMMA (acrylonitrile butadiene styrene-polymethyl methacrylate).
  • each of the connecting pieces comes from a manufacture according to a single dimension which corresponds to an extension for a so-called largest dimension base model, said connecting piece being intended to be if necessary cut (particularly on site) to form a shorter length extension associated with a shorter base model.
  • a single connecting piece makes it possible, by cutting it to the desired length, to adapt to the desired length of the base, and therefore makes it possible to adapt to several models of base. The manufacturing process is further simplified.
  • the invention also relates to a base of the invention which is used in particular to fix a smoke outlet or a skylight to a roof opening.
  • the term “external” is understood to qualify a surface which is facing the external environment, and on the contrary the term “internal” qualifies a surface intended to be facing the roof covering. or directly in contact with another surface.
  • the term “interior” relating to a base element means facing the base opening, while “exterior” means facing in a direction opposite to the base opening. .

  • the end pieces 4A and 4B and the connecting pieces 5 when the latter are present are designed to form the base 1 and the closed perimeter of the opening 10 of the base.
  • the number of parts depends on the geometry to be given to the base.
  • the base 1 usually has a square shape ( figure 4 ) or a rectangular shape ( figure 3 , 5 and 6 ).
  • the base of the invention designed in multiple pieces could apply to other geometries such as other polygonal shapes (triangular or otherwise), or circular shapes.
  • the design of the base in a plurality of parts gives it a modular function as to the dimension of its perimeter. This design also makes it possible to save space when not using the base, and to handle the base more easily before its installation.
