Description

La présente invention concerne des éléments de couverture synthétiques et leur procédé de réalisation.The present invention relates to synthetic roofing elements and their production method.

On sait que pour suppléer certains éléments de couverture classiques, tels que tuiles, ardoises, etc..., on a déjà pensé à fabriquer de tels éléments, à partir d'autres matériaux que les matières naturelles dans lesquelles ils ont toujours été réalisés. Ainsi, on obtient des éléments de construction moins chers qui abaissent d'autant les coûts de la construction dans laquelle ils rentrent. Toutefois, on s'est aperçu à l'usage, d'une part que ces éléments nouveaux n'offraient pas une grande résistance à l'érosion des intempéries, d'autre part que leur aspect esthétique n'était pas satisfaisant.We know that to supplement certain conventional roofing elements, such as tiles, slates, etc., we have already thought of manufacturing such elements, from materials other than the natural materials in which they have always been made. Thus, we obtain cheaper construction elements which lower the costs of the construction in which they fit. However, it has become clear in use, on the one hand that these new elements do not offer great resistance to weathering, on the other hand that their aesthetic appearance was not satisfactory.

La présente invention a pour objet de remédier à ces inconvénients. Elle concerne des éléments de couverture, réalisés en une matière de synthèse, résistant parfaitement bien à l'érosion et capables, si nécessaire, de ressembler aux éléments de construction classiques utilisés couramment, au point de s'y méprendre.The object of the present invention is to remedy these drawbacks. It relates to roofing elements, made of a synthetic material, perfectly resistant to erosion and capable, if necessary, of resembling the conventional building elements commonly used, to the point of being mistaken.

A cette fin, selon l'invention, un élément de construction est remarquable en ce qu'il est réalisé en une matière synthétique telle que le polyéthylène, le polypropylène ou le chlorure de polyvinyle additionnée d'au moins une charge et de noir de carbone.To this end, according to the invention, a building element is remarkable in that it is made of a synthetic material such as polyethylene, polypropylene or polyvinyl chloride added with at least one filler and carbon black. .

On obtient ainsi un élément de couver ban marché et inaltérable, dans lequel le noir de carbone sert à la fois d'agent lui conférant une bonne résistance aux rayons ultraviolets et de colorant.One thus obtains a market-proof and unalterable cover element, in which the carbon black serves both as an agent giving it good resistance to ultraviolet rays and as a dye.

La charge peut être minérale, végétale ou organique. Toutefois il est avantageux d'utiliser une charge minérale telle que la craie, le kaolin, la dolomie, le talc ou une matière analogue. De plus, l'élément comporte au moins un agent ignifuge.The filler can be mineral, vegetable or organic. However, it is advantageous to use a mineral filler such as chalk, kaolin, dolomite, talc or the like. In addition, the element comprises at least one flame retardant.

Pour obtenir l'élément selon l'invention, on peut mélanger la matière synthétique en particules divisées aux différentes charges et adjuvants, après quoi on approvisionne une extrudeuse avec ledit mélange, ladite extrudeuse présentant une filière correspondant à la section de l'élément à obtenir.To obtain the element according to the invention, the synthetic material can be mixed into divided particles with the different fillers and additives, after which an extruder is supplied with said mixture, said extruder having a die corresponding to the section of the element to be obtained. .

L'élément selon l'invention peut être réalisé à partir d'une matière synthétique vierge. Toutefois, il est particulièrement avantageux que la matière synthétique provienne de la récupération d'objets ou de déchets.The element according to the invention can be made from a virgin synthetic material. However, it is particularly advantageous for the synthetic material to come from the recovery of objects or waste.

Le produit sortant de l'extrudeuse peut être soumis à un calandrage.The product leaving the extruder can be subjected to calendering.

  • Les figures 6 et 7 illustrent respectivement à plat et plie un ensemble d'ardoises selon l'invention, destiné à faciliter la pose de celles-ci.
The figures of the appended drawing will make it clear how the invention can be implemented.
  • Figure 1 is a perspective view of a synthetic slate according to the invention.
  • FIG. 2 illustrates part of a method for manufacturing the slate of FIG. 1.
  • Figure 3 is a section along line III-III of the figure
  • Figure 4 illustrates in side view an alternative embodiment of the slate according to the invention.
  • FIG. 5 schematically illustrates the installation of slates in accordance with FIG. 4.
  • Figures 6 and 7 respectively illustrate flat and folds a set of slates according to the invention, intended to facilitate the installation thereof.

L'élément de couverture 1 selon l'invention, montré en perspective sur la figure 1, est destiné à remplacer les ardoises naturelles, aussi bien dans leurs utilisations que dans leur aspect esthétique.The covering element 1 according to the invention, shown in perspective in FIG. 1, is intended to replace natural slates, both in their uses and in their aesthetic appearance.

Pour ce faire, cet élément 1 se présente sous la forme rectangulaire aplatie usuelle, avec des bords 2 à épaisseur décroissant par gradins.To do this, this element 1 is in the usual flattened rectangular shape, with edges 2 of decreasing thickness in steps.

Pour réaliser une telle ardoise, on peut partir de déchets de polyéthylène, de polypropylène, de chlorure de polyvinyle, de récupération. Il peut s'agir de films, par exemple d'emballage, des sacs, etc... Ces films sont alors introduits dans un densifieur (cuve pourvue d'une hélice de malaxage) et sont densifiés avec introduction d'eau, jusqu'à ce qu'on obtienne une "semoule" de polyéthylène, de polypropylène ou de chlorure de polyvinyle. Lesdits déchets peuvent également être <compacts (rebuts ou carottes de fabrication par exemplé) ; dans ce cas, ils sont simplement broyés jusqu'à l'obtention d'une poudre ou de particules.To make such a slate, it is possible to start from waste polyethylene, polypropylene, polyvinyl chloride, recovery. These may be films, for example packaging, bags, etc. These films are then introduced into a densifier (tank provided with a mixing propeller) and are densified with the introduction of water, up to to obtain a "semolina" of polyethylene, polypropylene or polyvinyl chloride. Said waste can also be <compact (scrap or production carrots for example); in this case, they are simply ground until a powder or particles are obtained.

La matière ainsi préparée est ensuite introduite dans une tour à hélice verticale mélangeuse, avec les adjuvants désirés. On remarquera qu'en fonction des qualités de souplesse ou de rigidité recherchées pour le produit final, on peut introduire dans ladite tour une matière synthétique provenant soit de déchets à basse densité, soit de déchets à haute densité, ou. encore d'un mélange des deux ou de déchets à moyenne densité.The material thus prepared is then introduced into a vertical mixing propeller tower, with the desired adjuvants. It will be noted that, depending on the qualities of flexibility or rigidity desired for the final product, it is possible to introduce into said tower a synthetic material originating either from low density waste, or from high density waste, or. still a mixture of the two or medium density waste.

Parmi les adjuvants, on choisit une charge minérale, végétale ou organique, par exemple une charge minérale telle que la craie, la dolomie, le talc, etc... Ces adjuvants peuvent comprendre également au moins un agent antifeu et au moins un agent dispersant des adjuvants dans la matière synthétique.Among the adjuvants, a mineral, vegetable or organic filler is chosen, for example a mineral filler such as chalk, dolomite, talc, etc. These adjuvants can also comprise at least one fire-retardant agent and at least one dispersing agent adjuvants in synthetic material.

Pour réaliser une ardoise synthétique du type de celle montrée par la figure, on peut utiliser la composition en poids suivante :

Figure imgb0001
On remarquera que le noir de carbone, en plus de son rôle de protection contre les rayons ultraviolets, est un.colorant , puissant. Le pouvoir colorant du noir de carbone est souvent un inconvénient sérieux à l'utilisation de celui-ci comme agen de protection,contre les rayons ultraviolets, puisque les objets qui le contiennent sont alors obligatoirement de teinte foncée. Dans le présent cas d'application, le noir de carbone permet simultanément de donner aux éléments de couverture selo l'invention une couleur pratiquement identique à celle des ardoises naturelles.To make a synthetic slate like the one shown by the figure, the following composition by weight can be used:
Figure imgb0001
 It will be noted that carbon black, in addition to its role of protection against ultraviolet rays, is a colorant, powerful. The coloring power of carbon black is often a serious drawback to the use of it as a protective agent, against ultraviolet rays, since the objects which contain it are then necessarily of dark shade. In the present application, carbon black simultaneously makes it possible to give the selo roofing elements of the invention a color practically identical to that of natural slates.

Le mélange homogène apparaissant à la sortiede la tour mélangeuse est introduit dans une boudineuse-extrudeuse, à la sorti de laquelle est prévu un dispositif de calandrage.The homogeneous mixture appearing at the outlet of the mixing tower is introduced into a extruder-extruder, at the outlet of which is provided a calendering device.

La boudineuse-extrudeuse fournit à sa sortie une bande plate sans fin 3 et dans cette bande, le dispositif de calandrage détermine une pluralité d'ardoises 1, séparées par des lignes séparation 4 formant les bords étagés 2 d'ardoises contiguës et imprime sur chaque ardoise 1 des dessins superficiels 5 imitant l'aspect de la véritable ardoise (voir figures 2 et 3). Les lignes de'séparation 4 peuvent être découpées soit au mome du calandrage, soit après celui-ci, pour obtenir des ardoises individuelles.The extruder extruder provides at its outlet an endless flat strip 3 and in this strip, the calendering device determines a plurality of slates 1, separated by separation lines 4 forming the stepped edges 2 of contiguous slates and prints on each slate 1 of the surface drawings 5 imitating the appearance of the real slate (see Figures 2 and 3). The separation lines 4 can be cut either at the time of the calendering, or after it, to obtain individual slates.

On obtient ainsi des ardoises présentant le même aspect que les ardoises véritables, légères (300 g pour des dimensions de 32 cm x 22 cm), ignifuges et totalement inaltérables.Slates are thus obtained which have the same appearance as real slates, light (300 g for dimensions of 32 cm x 22 cm), fireproof and completely unalterable.

Bien entendu, de telles ardoises pourraient également être obtenues par injection ou par moulage par compression.Of course, such slates could also be obtained by injection or by compression molding.

Sur la figure 4, on a représenté une variante de réalisation de l'élément de couverture 1 selon l'invention. Dans ce cas, les éléments comportent des ergots 6, par exemple obtenus par pressage, le long de leurs bords longitudinaux, permettant leur positionnement précis au moment de la pose, par appui desdits ergots 6 sur le bord transversal supérieur 7 des éléments sous- jacents (voir la figure 5). La pose des ardoises 1 individuelles peut être effectuée de façon connue par cloutage ou au moyen de crochets. Il est également possible d'obtenir directement, par exemple par calandrage, des panneaux imitant des rangées d'ardoises déjà posées et de réaliser un toit par pose de tels panneaux et non par pose d'ardoises synthétiques individuelles.In Figure 4, there is shown an alternative embodiment of the cover element 1 according to the invention. In this case, the elements include lugs 6, for example obtained by pressing, along their longitudinal edges, allowing their precise positioning at the time of installation, by pressing said lugs 6 on the upper transverse edge 7 of the underlying elements. (see figure 5). The installation of the individual slates 1 can be carried out in a known manner by nailing or by means of hooks. It is also possible to obtain directly, for example by calendering, panels imitating rows of slates already laid and to make a roof by laying such panels and not by laying individual synthetic slates.

Pour faciliter la pose d'ardoises synthétiques individuelles, on peut prévoir comme le montrent les figures 6 et 7, des ensembles 8 d'ardoises 1 reliées le long d'au moins une partie de leurs bords latéraux par des lignes d'articulation 9 de moindre épaisseur. Ainsi, ces ensembles 8 peuvent être repliés en zigzag (figure 7) pour former des ensembles compacts faciles à stocker et à transporter. Au moment de la pose, les ensembles 8 sont dépliés, et mis à plat pour permettre la mise en place simultanée des ardoises d'un ensemble. De préférence, à des fins esthétiques, les lignes d'articulation 9 ne s'étendent que sur une longueur 1 égale ou inférieure à la longueur L de recouvrement de deux rangées d'ardoises successives, de façon à être cachées par les ardoises de la rangée supérieure. Sur le reste de la longueur des ardoises, deux ardoises consécutives 1 d'un ensemble 8 sont séparées par une fente 10, correspondant à un écartement normal de pose.To facilitate the installation of individual synthetic slates, it can be provided, as shown in FIGS. 6 and 7, of sets 8 of slates 1 connected along at least part of their lateral edges by articulation lines 9 of less thickness. Thus, these sets 8 can be folded in a zigzag (Figure 7) to form compact sets easy to store and transport. At the time of installation, the sets 8 are unfolded, and laid flat to allow the simultaneous establishment of slates of a set. Preferably, for aesthetic purposes, the articulation lines 9 extend only over a length 1 equal to or less than the length L of covering two rows of successive slates, so as to be hidden by the slates of the top row. Over the rest of the length of the slates, two consecutive slates 1 of a set 8 are separated by a slot 10, corresponding to a normal installation spacing.
