Description
La présente invention concerne un moule réalisé à l'aide d'au moins uneThe present invention relates to a mold produced using at least one
structure gonflable.inflatable.
Elle s'applique notamment, mais non exclusivement, au moulage d'éléments structuraux, par exemple en béton, utilisables en particulier dans le bâtiment et It applies in particular, but not exclusively, to the molding of structural elements, for example concrete, usable in particular in the building and
les travaux publics.public works.
Elle se base sur la constatation qu'il existe, à l'heure actuelle, des structures gonflables pouvant atteindre des dimensions importantes et présenter une multiplicité de formes. Ces structures dont les parois sont tendues sous l'effet It is based on the observation that, at present, inflatable structures can reach large dimensions and have a multiplicity of shapes. These structures whose walls are stretched under the effect
de la pression d'air intérieure, présentent une bonne rigidité. internal air pressure, have good rigidity.
Il est clair que l'avantage de ces structures consiste en ce qu'elles sont relativement légères et qu'à l'état dégonflé, elles peuvent être repliées de manière à n'occuper qu'un très faible volume, relativement à leur volume à l'état gonflé. Ainsi, même lorsqu'elles présentent d'importantes dimensions, It is clear that the advantage of these structures is that they are relatively light and that in the deflated state, they can be folded up so as to occupy only a very small volume, relatively to their volume at swollen state. So even when they are large,
elles sont facilement transportables, manipulables et de mise en oeuvre aisée. they are easily transportable, easy to handle and easy to use.
L'invention propose donc un moule comprenant au moins une structure gonflable à l'aide d'un gaz et/ou d'un fluide qui délimite, à l'état gonflé, un volume de moulage dans lequel la matière de moulage peut être introduite, le démoulage de l'objet s'effectuant après la prise de la matière grâce au The invention therefore provides a mold comprising at least one inflatable structure using a gas and / or a fluid which delimits, in the inflated state, a molding volume into which the molding material can be introduced. , the mold is removed from the object after the material has set, thanks to the
dégonflage de la structure.deflation of the structure.
-2- I s'avère qu'en plus des avantages attendus précédemment évoqués, cette solution permet de résoudre d'une façon extrêmement simple les problèmes de démoulage des formes "indémoulables" telles que, par exemple, les formes en contre-dépouille, les cavités ou les excroissances: A l'état dégonflé, la face de -2- It turns out that in addition to the expected advantages mentioned above, this solution makes it possible to solve in an extremely simple manner the problems of demolding of the "non-moldable" forms such as, for example, the undercut forms, cavities or growths: In the deflated state, the face of
moulage retrouve toute sa souplesse et peut donc être facilement ôtée. molding regains its flexibility and can therefore be easily removed.
Selon un mode d'exécution de l'invention, le moule comprend deux structures gonflables reliées l'une à l'autre par des moyens de liaison tels que, par According to one embodiment of the invention, the mold comprises two inflatable structures connected to each other by connecting means such that, by
exemple, des tirants.example, tie rods.
Avantageusement, le moule pourra résulter de l'assemblage de plusieurs éléments modulaires comprenant chacun deux structures de moulage présentant deux surfaces de moulage verticales, au moins en partie planes, parallèles l'une par rapport à l'autre et qui délimitent un volume de moulage sensiblement parallélépipédique. Ces deux structures de moulage peuvent être reliées entre elles soit par des tirants détachables reliant les bords latéraux de la structure, soit par des tirants perdus s'étendant entre les deux faces de moulage, ou encore par des formes convexes de la face de moulage de l'une des structures venant en contact avec la face de moulage de l'autre structure Advantageously, the mold may result from the assembly of several modular elements each comprising two molding structures having two vertical molding surfaces, at least in part plane, parallel to one another and which delimit a molding volume. substantially parallelepiped. These two molding structures can be connected together either by detachable tie rods connecting the lateral edges of the structure, or by lost tie rods extending between the two molding faces, or by convex shapes of the molding face of one of the structures coming into contact with the molding face of the other structure
pour former des ouvertures ou des échancrures dans l'objet moulé. to form openings or notches in the molded object.
Par ailleurs, les bords latéraux des faces de moulage pourront être reliés à des bords latéraux de faces de moulage de structures gonflables adjacentes, de manière à assurer à la fois une liaison mécanique déconnectable et une Furthermore, the lateral edges of the molding faces may be connected to the lateral edges of the molding faces of adjacent inflatable structures, so as to provide both a disconnectable mechanical connection and a
continuité de forme à la jonction entre les faces de moulage. continuity of shape at the junction between the molding faces.
Des modes d'exécution de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, avec référence aux dessins annexés dans lesquels: -3 - La figure 1 est une représentation schématique, en perspective, d'un moule constitué en une seule structure gonflable pour la réalisation d'objets cylindriques; La figure 2 est une vue schématique, en perspective, d'un élément modulaire utilisant deux structures gonflables; La figure 3 représente schématiquement, en perspective, un moule permettant la réalisation d'une cellule parallélépipédique pouvant par exemple consister en les murs d'une pièce d'habitation: La figure 4 est une coupe transversale schématique illustrant l'assemblage de deux structures gonflables adjacentes d'un moule; La figure 5 est une coupe transversale verticale d'un élément modulaire permettant d'obtenir une paroi munie d'un orifice tel qu'une fenêtre; La figure 6 est une coupe transversale d'un moule pour la réalisation Embodiments of the invention will be described below, by way of nonlimiting examples, with reference to the accompanying drawings in which: -3 - Figure 1 is a schematic representation, in perspective, of a mold made in a single inflatable structure for the production of cylindrical objects; Figure 2 is a schematic perspective view of a modular element using two inflatable structures; FIG. 3 schematically represents, in perspective, a mold allowing the production of a parallelepipedal cell which can for example consist of the walls of a living room: FIG. 4 is a schematic cross section illustrating the assembly of two inflatable structures adjacent to a mold; Figure 5 is a vertical cross section of a modular element for obtaining a wall provided with an orifice such as a window; Figure 6 is a cross section of a mold for the realization
d'une cheminée.a fireplace.
Tel que représenté sur la figure 1, le moule M présente, à l'état gonflé, une forme tubulaire cylindrique dont la surface cylindrique intérieure Sl constitue une surface de moulage délimitant un volume de moulage cylindrique V aux dimensions de l'objet. Le démoulage de l'objet peut s'effectuer ici par simple dégonflage de la structure: Ce dégonflage engendre un accroissement du diamètre de la face de moulage Si et un assouplissement de l'ensemble de la structure. Dans le cas o ce démoulage serait mal aisé, voire impossible, le moule pourra présenter une fente axiale longitudinale F s'étendant de la surface extérieure S2 à la surface intérieure Sl du moule M, cette fente F permettant l'ouverture du moule M sur toute sa longueur. La fermeture du moule M pourra être obtenue -4- au moyen d'une fermeture à glissière E prévue au niveau de la face de moulage Si et une fermeture à oeillets O et lacet L prévue au niveau de la face As shown in Figure 1, the mold M has, in the inflated state, a cylindrical tubular shape whose inner cylindrical surface Sl constitutes a molding surface defining a cylindrical molding volume V to the dimensions of the object. The object can be removed from the mold here by simple deflation of the structure: This deflation generates an increase in the diameter of the molding face Si and a softening of the entire structure. In the case where this demolding would be difficult or even impossible, the mold could have a longitudinal axial slot F extending from the outer surface S2 to the inner surface Sl of the mold M, this slot F allowing the opening of the mold M on its entire length. The closure of the mold M can be obtained by means of a zipper E provided at the level of the molding face Si and a closure with eyelets O and lace L provided at the level of the face

Dans l'exemple de la figure 2, l'élément modulaire de moule 1 comprend deux structures gonflables 2, 3 qui, à l'état gonflé, présentent chacune une forme parallélépipédique comportant une face de moulage plane verticale 4, 5, une face arrière 6, 7, deux faces latérales verticales 8, 9 et deux faces latérales In the example of FIG. 2, the modular mold element 1 comprises two inflatable structures 2, 3 which, in the inflated state, each have a parallelepiped shape having a vertical flat molding face 4, 5, a rear face 6, 7, two vertical side faces 8, 9 and two side faces
horizontales 10, 11.horizontal 10, 11.
Ces deux structures sont disposées côte à côte de manière à ce que les parois de moulage 4, 5 s'étendent parallèlement l'une à l'autre et délimitent entre elles These two structures are arranged side by side so that the molding walls 4, 5 extend parallel to one another and delimit between them
un volume de moulage parallélépipédique. a volume of parallelepiped molding.
Le maintien en position des deux structures 2, 3, l'une par rapport à l'autre, est assuré au moyen d'éléments de liaison tels que des tirants 12, 13 reliant entre elles les faces latérales horizontales respectivement supérieure 11, et inférieure 10. Par ailleurs, les deux structures 2, 3 comprennent une pluralité de gaines transversales G reliant la face de moulage 4, 5 à la face arrière 6, 7. Par ces gaines transversales G passent des tirants T qui traversent le volume de moulage pour assurer une liaison entre les faces arrières 6, 7 des deux The two structures 2, 3 are held in position relative to each other by means of connecting elements such as tie rods 12, 13 connecting the horizontal side faces 11, respectively 11 and the bottom 10. Furthermore, the two structures 2, 3 comprise a plurality of transverse sheaths G connecting the molding face 4, 5 to the rear face 6, 7. Through these transverse sheaths G pass tie rods T which pass through the molding volume for ensuring a connection between the rear faces 6, 7 of the two
structures 2, 3.structures 2, 3.
L'assemblage de deux éléments modulaires El, E2 s'effectue en juxtaposant les faces transversales verticales 8, 9 situées d'un même côté des deux structures de l'un des éléments El avec les faces transversales correspondantes des deux The assembly of two modular elements El, E2 is carried out by juxtaposing the vertical transverse faces 8, 9 situated on the same side of the two structures of one of the elements El with the corresponding transverse faces of the two
