Description

La présente invention a pour objet un panneau de revêtement, notamment d'isolation, réalisé en un matériau rigide ou semi-rigide, comme par exemple une mousse phénolique, de polyuréthane ou de polystyrène, et destiné au revêtement de structures comportant au moins une courbure telles que tuyauteries, boîtes à vannes, à brides, etc.The subject of the present invention is a covering panel, in particular an insulation panel, made of a rigid or semi-rigid material, such as for example a phenolic, polyurethane or polystyrene foam, and intended for the coating of structures comprising at least one curvature. such as piping, valve boxes, flanges, etc.

L'isolation des tuyauteries requiert l'utilisation d'éléments de revêtement dont la surface interne présente une courbure prédéterminée, adaptée au diamètre de ces tuyauteries.The insulation of the pipes requires the use of covering elements whose internal surface has a predetermined curvature, adapted to the diameter of these pipes.

On désigne par surface interne, la surface destinée à venir au contact, ou au voisinage de la surface à recouvrir.The term internal surface designates the surface intended to come into contact with, or in the vicinity of the surface to be covered.

On connaît déjà plusieurs solutions pour l'isolation des tuyauteries de diamètre important. C'est ainsi qu'on a réalisé des éléments de revêtement spécifiques, sous forme de coquilles en une ou deux pièces obtenues par découpe d'un bloc de matériau rigide ou semi-rigide.Several solutions are already known for insulating large diameter pipes. This is how specific coating elements have been produced, in the form of shells in one or two pieces obtained by cutting a block of rigid or semi-rigid material.

Cependant, le prix de revient de ces éléments est relativement élevé, notamment en raison des pertes de matériau lors de la découpe. De plus, les dimensions de ces éléments sont limitées par l'épaisseur du matériau de départ utilisé.However, the cost price of these elements is relatively high, in particular due to the loss of material during cutting. In addition, the dimensions of these elements are limited by the thickness of the starting material used.

C'est pourquoi on s'est orienté vers des éléments de plus faibles dimensions dénommés douelles, qui sont en fait des portions de coquilles découpées en segments. Cependant, il faut généralement monter plusieurs douelles autour d'une tuyauterie, pour l'isoler complètement, ce qui entraîne un temps de pose très important.This is why we have turned to elements of smaller dimensions called staves, which are in fact portions of shells cut into segments. However, it is generally necessary to mount several staves around a pipe, to completely isolate it, which results in a very long installation time.

De plus, en raison de la multiplicité des joints, les risques de pertes thermiques sont amplifiés.In addition, due to the multiplicity of seals, the risks of heat loss are amplified.

Par ailleurs, afin d'améliorer le "rendement matière", en évitant les chutes lors de la découpe, on a proposé des éléments de revêtement sous forme de panneaux ou plaques en un matériau rigide ou semi-rigide, comportant au moins une zone déformable susceptible de prendre une courbure quelconque prédéterminée, comportant un ensemble de rainures généralement en forme de V, transversales parallèles et espacées s'étendant sur une majeure partie de l'épaisseur du panneau, depuis la surface interne de celui-ci en définissant ainsi un ensemble d'éléments à section transversale trapézoïdale, assemblables par accolement lors de la mise en oeuvre du matériau.Furthermore, in order to improve the "material yield", by avoiding falls during cutting, coating elements have been proposed in the form of panels or plates made of a rigid or semi-rigid material, comprising at least one deformable zone. likely to take any predetermined curvature, comprising a set of grooves generally in V-shape, parallel and spaced transverses extending over a major part of the thickness of the panel, from the internal surface of the latter, thus defining a set of elements with trapezoidal cross-section, which can be assembled together when joined of the material.

Cependant, les panneaux rainurés ne sont utilisables que pour les tuyauteries de très grand diamètre et souffrent de divers inconvénients. En particulier, ces panneaux sont fragiles et cassent fréquemment au niveau de la base des rainures.However, grooved panels can only be used for very large diameter pipes and suffer from various drawbacks. In particular, these panels are fragile and frequently break at the base of the grooves.

De plus, ces panneaux présentent une forme polygonale qui s'adapte mal, tant à l'intérieur qu'à l'extérieur de la tuyauterie à la forme cylindrique de celle-ci.In addition, these panels have a polygonal shape which adapts poorly, both inside and outside the piping to the cylindrical shape thereof.

Enfin, les rainures sont peu jointives et facilitent les pertes thermiques.Finally, the grooves are not very contiguous and facilitate heat loss.

Le premier but de l'invention est de résoudre le problème technique consistant en la fourniture d'un panneau de revêtement qui est adapté pour permettre la réalisation de courbures variées, dont le rayon peut être très faible, et qui ne présente aucune zone de fragilité.The first object of the invention is to solve the technical problem consisting in the provision of a covering panel which is adapted to allow the production of various curvatures, the radius of which can be very small, and which does not have any brittleness zone. .

La solution conforme à la présente invention, pour atteindre ce premier objectif consiste en un panneau de revêtement, notamment d'isolation, réalisé en un matériau rigide ou semi-rigide, comme par exemple une mousse phénolique, de polyuréthane ou de polystyrène, et destiné au revêtement de structures comportant au moins une courbure, telles que tuyauteries, boîtes à vannes, à brides, etc. du type comportant au moins une zone déformable comportant un ensemble de rainures transversales parallèles et espacées s'étendant sur une majeure partie de l'épaisseur dudit panneau, à partir de la surface interne de celui-ci, en définissant ainsi un ensemble d'éléments assemblables en position d'utilisation, caractérisé en ce que chaque rainure précitée est prolongée à sa base, de part et d'autre de son plan médian, et présente la forme générale d'un T définissant une semelle souple, dont la face externe est sensiblement plane, à laquelle lesdits éléments sont reliés par une partie formant pied, de faible largeur, définie par l'espace formé entre les parties correspondant à la barre transversale du T de deux rainures consécutives.The solution according to the present invention, to achieve this first objective consists of a covering panel, in particular of insulation, made of a rigid or semi-rigid material, such as for example a phenolic, polyurethane or polystyrene foam, and intended the coating of structures having at least one curvature, such as piping, valve boxes, flanges, etc. of the type comprising at least one deformable zone comprising a set of spaced parallel transverse grooves extending over a major part of the thickness of said panel, from the internal surface thereof, thereby defining a set of elements assembled in the position of use, characterized in that each aforementioned groove is extended at its base, on either side of its median plane, and has the general shape of a T defining a flexible sole, the external face of which is substantially planar, to which said elements are connected by a foot portion, of small width, defined by the space formed between the parts corresponding to the crossbar of the T of two consecutive grooves.

Selon une caractéristique particulière de l'invention, la surface interne des éléments précités est conformée de telle sorte que ces éléments constituent, en position d'utilisation, une surface interne sensiblement continue de courbure quelconque prédéterminée.According to a particular characteristic of the invention, the internal surface of the aforementioned elements is shaped so that these elements constitute, in the position of use, a substantially continuous internal surface of any predetermined curvature.

Ainsi, contrairement aux panneaux rainurés connus jusqu'à présent, qui présentent généralement une forme polygonale qui s'adapte mal, tant à l'intérieur qu'à l'extérieur aux surfaces courbes à recouvrir, un panneau de revêtement conforme à l'invention présente, en position d'utilisation, une courbure quelconque prédéterminée pouvant être adaptée parfaitement à une forme cylindrique par exemple.Thus, unlike the grooved panels known up to now, which generally have a polygonal shape which is ill-suited, both inside and outside to the curved surfaces to be covered, a covering panel according to the invention has, in the position of use, any predetermined curvature which can be perfectly adapted to a cylindrical shape for example.

Pour parfaire cet objectif, en particulier au niveau de la surface externe, chaque aile constituant la partie correspondant à la barre transversale du T de la fente s'étend sensiblement suivant un plan formant avec la face externe plane du panneau un angle aigu très faible. Ainsi, lors de la mise en oeuvre dudit matériau les éléments formant la partie déformable viennent s'assembler deux à deux successivement, tandis que la semelle constitue par déformation une surface externe dont la courbure est sensiblement identique à la courbure interne définie par les éléments assemblés.To perfect this objective, in particular at the level of the external surface, each wing constituting the part corresponding to the transverse bar of the T of the slot extends substantially along a plane forming with the planar external face of the panel a very small acute angle. Thus, during the implementation of said material, the elements forming the deformable part come together two by two successively, while the sole constitutes by deformation an external surface whose curvature is substantially identical to the internal curvature defined by the assembled elements. .

Selon une autre caractéristique particulièrement avantageuse de l'invention, chaque fente, dans sa partie correspondant à la barre verticale du T, est réalisée suivant un profil définissant sur chaque élément précité des moyens d'assemblage par emboîtement avec les éléments adjacents voisins.According to another particularly advantageous characteristic of the invention, each slot, in its part corresponding to the vertical bar of the T, is produced according to a profile defining on each aforementioned element assembly means by interlocking with adjacent adjacent elements.

Cette réalisation permet de limiter dans une large mesure les pertes thermiques, en réalisant des barrières anti-fuites au niveau des joints entre éléments.This embodiment makes it possible to limit thermal losses to a large extent, by creating leakage barriers at the joints between elements.

L'invention sera mieux comprise, et d'autres buts, détails et avantages de celle-ci apparaîtront plus clairement à la lecture de la description explicative qui va suivre, faite en référence aux dessins schématiques annexés, donnés uniquement à titre d'exemples non limitatifs illustrant un mode de réalisation actuellement préféré de l'invention, et dans lesquels :

The invention will be better understood, and other objects, details and advantages thereof will appear more clearly on reading of the explanatory description which will follow, made with reference to the appended schematic drawings, given only by way of nonlimiting examples illustrating a currently preferred embodiment of the invention, and in which:
  • . Figure 1 shows a partial perspective view of a covering panel according to the invention, at a deformable area, shown in the free state;

On a représenté aux figures 1 à 3 un panneau de revêtement, selon un mode de réalisation actuellement préféré de l'invention, spécifiquement destiné au revêtement d'une surface cylindrique, telle que par exemple une tuyauterie.FIGS. 1 to 3 show a covering panel, according to a currently preferred embodiment of the invention, specifically intended for covering a cylindrical surface, such as for example a pipe.

Les figures 1 et 3 représentent respectivement partiellement et dans sa totalité ce panneau dans sa conformation à plat de repos (non-utilisation), tandis que la figure 2 représente une partie de ce panneau, dans sa conformation d'utilisation.Figures 1 and 3 respectively respectively partially and in its entirety this panel in its conformation flat rest (not in use), while Figure 2 shows a part of this panel, in its conformation of use.

Comme on le voit, ce panneau comporte un ensemble de fentes sensiblement identiques, s'étendant unidirectionnellement de façon espacée, présentant une forme générale de T, dont la partie correspondant à la barre verticale du T s'étend transversalement sur une majeure partie de l'épaisseur du panneau, depuis la surface interne de celui-ci.As can be seen, this panel comprises a set of substantially identical slots, extending unidirectionally in a spaced manner, having a general shape of T, the part corresponding to the vertical bar of the T extending transversely over a major part of the 'thickness of the panel, from the internal surface thereof.

Ces fentes définissent une zone déformable constituée d'une semelle souple 1 dont la face 2 destinée à constituer la surface externe du matériau, lors de la mise en oeuvre, est sensiblement plane ; et un ensemble d'éléments 3 disposés unidirectionnellement de façon espacée sur la semelle 2, en étant reliés à celle-ci par une partie formant pied 4, de faible largeur définie par l'espace forme entre les parties correspondant à la barre transversale du T de deux rainures consécutives.These slots define a deformable zone consisting of a flexible sole 1 whose face 2 intended to constitute the external surface of the material, during processing, is substantially planar; and a set of elements 3 arranged unidirectionally in a spaced manner on the sole 2, by being connected to the latter by a part forming a foot 4, of small width defined by the space formed between the parts corresponding to the transverse bar of the T of two consecutive grooves.

Comme on le comprend, il est possible d'obtenir une grande souplesse, et donc une courbure quelconque en diminuant au maximum (compatible avec la résistance d'ensemble) cet espace et donc la largeur de la partie 4.As can be understood, it is possible to obtain great flexibility, and therefore any curvature by reducing as much as possible (compatible with the overall resistance) this space and therefore the width of the part 4.

Chaque élément 3 présente une forme généralement cylindrique à section tansversale constante dont le contour est spécifiquement conçu en fonction de la courbure que l'on souhaite donner au matériau lors de l'utilisation.Each element 3 has a generally cylindrical shape with a constant transverse section, the outline of which is specifically designed as a function of the curvature which it is desired to give to the material during use.

Dans l'exemple représenté, chaque élément 3 est pourvu de moyens d'assemblage par emboîtement avec ses deux éléments adjacents voisins. Plus précisément, chaque élément est pourvu sur un bord longitudinal d'une partie en saillie 5 et sur son bord longitudinal opposé d'une partie formant logement 6 de forme conjuguée à ladite partie en saillie 5.In the example shown, each element 3 is provided with means of assembly by interlocking with its two adjacent adjacent elements. More precisely, each element is provided on a longitudinal edge with a projecting part 5 and on its opposite longitudinal edge with a part forming a housing 6 of shape conjugate to said projecting part 5.

Ces moyens d'assemblage par emboîtement permettent d'augmenter la stabilité du panneau de revêtement, de favoriser sa mise en oeuvre par guidage et, de limiter les pertes thermiques lorsque ce panneau est utilisé comme élément d'isolation thermique.These assembly means by interlocking make it possible to increase the stability of the covering panel, to favor its implementation by guidance and, to limit the heat losses when this panel is used as a thermal insulation element.

La surface interne 7 de chaque élément est profilée de telle sorte que les éléments 3 constituent, après emboîtement, une surface interne sensiblement continue, de courbure quelconque prédéterminée. On peut ainsi revêtir des tuyauteries de diamètres quelconques, en faisant varier le nombre d'éléments 3 et la courbure spécifique de leur surface interne.The internal surface 7 of each element is profiled so that the elements 3 constitute, after fitting, a substantially continuous internal surface, of any predetermined curvature. It is thus possible to coat pipes of any diameter, by varying the number of elements 3 and the specific curvature of their internal surface.

Comme le montrent les figures 1 et 3, la partie correspondant à la barre transversale du T, de chaque fente présente la forme d'un V ouvert, c'est-à-dire que chaque aile 8, 8′, constituant cette partie s'étend sensiblement suivant un plan formant avec la surface externe plane 2 de la semelle 1 un angle aigu très faible dont la valeur sera déterminée en fonction de la courbure recherchée.As shown in FIGS. 1 and 3, the part corresponding to the crossbar of the T, of each slot has the shape of an open V, that is to say that each wing 8, 8 ′, constituting this part extends substantially along a plane forming with the flat external surface 2 of the sole 1 a very small acute angle, the value of which will be determined as a function of the desired curvature.

La semelle 1 présente, au niveau de la partie se trouvant en vis-à-vis de la base de la portion transversale de la rainure (correspondant à la barre verticale du T) une surépaisseur. Cette surépaisseur facilite la déformation de la semelle 1 lors de la mise en oeuvre du matériau, les portions des éléments 3 venant au contact de cette surépaisseur lors de la mise en oeuvre et créant une force radiale externe au niveau de cette surépaisseur.The sole 1 has, at the part located opposite the base of the transverse portion of the groove (corresponding to the vertical bar of the T) an extra thickness. This additional thickness facilitates the deformation of the sole 1 during the use of the material, the portions of the elements 3 coming into contact with this additional thickness during implementation and creating an external radial force at this additional thickness.

La largeur de la rainure au niveau de la portion correspondant à la barre verticale du T sera déterminée en fonction de la courbure à obtenir et décroît de la surface interne du panneau à sa base.The width of the groove at the portion corresponding to the vertical bar of the T will be determined according to the curvature to be obtained and decreases from the internal surface of the panel to its base.

Comme le montre la figure 3, un panneau conforme à l'invention comporte le long de ses bords habituellement longitudinaux opposés des moyens d'assemblage (rainure 9 et languette 10) destinées à coopérer par emboîtement lors de la mise en oeuvre du matériau (voir figure 2).As shown in Figure 3, a panel according to the invention comprises along its usually longitudinal edges opposite assembly means (groove 9 and tongue 10) intended to cooperate by interlocking during the implementation of the material (see figure 2).

On a représenté aux figures 4 à 7 un panneau de revêtement spécifiquement destiné au revêtement d'une boîte à vannes.FIGS. 4 to 7 show a covering panel specifically intended for covering a valve box.

Ce panneau comporte, dans sa position d'utilisation, une partie formant un demi-cylindre prolongée de chaque côté par une partie rectiligne 12, 13 ; ces parties rectilignes étant reliées à l'aide d'éléments emboîtables complémentaires représentés respectivement aux figures 6 et 7.This panel comprises, in its position of use, a part forming a half-cylinder extended on each side by a rectilinear part 12, 13; these rectilinear parts being connected by means of complementary nesting elements shown respectively in FIGS. 6 and 7.

Les différentes découpes permettant de réaliser un panneau conforme à l'invention, par exemple à partir d'un bloc de matériau rigide ou semi-rigide, peuvent être facilement réalisées au moyen d'une machine de découpe à fil utilisée habituellement pour la transformation des mousses souples.The various cuts making it possible to produce a panel in accordance with the invention, for example from a block of rigid or semi-rigid material, can be easily carried out by means of a wire cutting machine usually used for the transformation of flexible foams.
