Description
L'invention a pour objet un dispositif d'abri. The invention relates to a shelter device.
Elle vise, notamment, un tel dispositif pouvant être obtenu par assemblage de modules et, plus particulièrement, un tel dispositif pouvant être réalisé par assemblage mécanique de modules identiques suivant une structure juxtaposable à d'autres structures identiques. It relates, in particular, to such a device which can be obtained by assembling modules and, more particularly, such a device which can be produced by mechanical assembly of identical modules according to a structure which can be juxtaposed with other identical structures.
C'est, d'une façon générale, un but de l'invention de fournir un tel dispositif qui ne nécessite pas de main d'oeuvre spécialisée pour sa construction ni, non plus, de moyens complexes de levage ou de portage comme cela est fréquemment requis pour des abris préfabriqués, de sorte qu'il peut être érigé sans difficulté pratiquement en tout lieu. It is, in general, an object of the invention to provide such a device which does not require specialized manpower for its construction nor, either, complex means of lifting or carrying as is frequently required for prefabricated shelters, so that it can be erected without difficulty in practically any place.
C'est, aussi, un but de l'invention de fournir un tel dispositif présentant de bonnes qualités d'habitabilité, notamment en ce qui concerne l'isolation thermique. It is also an object of the invention to provide such a device having good qualities of habitability, in particular with regard to thermal insulation.
Un dispositif d'abri propre à être construit par assemblage d'une pluralité d'éléments modulaires est caractérisé, selon l'invention, en ce que chacun des éléments est une coque conformée quelque peu suivant une partie de voûte ogivale et, en ce que ledit élément est en mousse de matière plastique expansée enfermée entre des peaux de surface en résine de polyester armée de fibres de verre. A shelter device suitable for being constructed by assembling a plurality of modular elements is characterized, according to the invention, in that each of the elements is a shell shaped somewhat along a part of the ogival arch and, in that said element is made of expanded plastic foam enclosed between surface skins of polyester resin reinforced with glass fibers.
Dans une forme de réalisation avantageuse, le dispositif d'abri selon l'invention est réalisé-par assemblage à l'aide de boulons ou analogues de quatre modules identiques accolés les uns aux autres suivant les arêtes de clef de voûte. In an advantageous embodiment, the shelter device according to the invention is produced by assembly, using bolts or the like, of four identical modules joined to one another along the keystone edges.
Dans une forme de réalisation préférée, l'abri peut être muni de panneaux sandwich auxiliaires destinés à former des cloisons extérieures ou de partition munies ou non de chambranles de portes, d'embrasures de fenêtres, etc, et qui sont en le même matériau que celui constitutif des éléments modulaires, c'est-à-dire en mousse de matière plastique expansée enfermée dans des peaux ou couches de surface externes en résine de polyester, avantageusement armée de fibres de verre. In a preferred embodiment, the shelter can be provided with auxiliary sandwich panels intended to form external partitions or partitions provided or not with door jambs, window frames, etc., and which are made of the same material as that constituting the modular elements, that is to say in expanded plastic foam enclosed in skins or outer surface layers of polyester resin, advantageously reinforced with glass fibers.
La mousse de matière plastique expansée est, dans une réalisation, une mousse de PVC expansé ou de polyuréthane expansée. The foam of expanded plastic is, in one embodiment, a foam of expanded PVC or expanded polyurethane.
Pour la fixation au sol du dispositif d'abri selon l'invention, on prévoit de poser les modules sur des dés en béton ou analogue dont font saillie des tiges filetées et de solidariser lesdites tiges aux modules à l'aide de boulons. For fixing to the ground the shelter device according to the invention, provision is made to place the modules on concrete dice or the like from which project threaded rods and to secure said rods to the modules using bolts.
Dans une forme de réalisation ayant donné de bons résultats en ce qui concerne l'isolation thermique les éléments modulaires ont une épaisseur de l'ordre de 45 mm, avec une âme en mousse de matière plastique expansée du type de celle vendue par la Demanderesse sous le nom commercial de
KLEGECELL (mousse de PVC expansé) d'une épaisseur de l'ordre de 40 mm et des peaux externes en résine polyester armée de fibre de verre.In one embodiment which has given good results with regard to thermal insulation, the modular elements have a thickness of the order of 45 mm, with a foam core of expanded plastic material of the type sold by the Applicant under the trade name of
KLEGECELL (expanded PVC foam) with a thickness of about 40 mm and external skins in polyester resin reinforced with fiberglass.
Ces dernières ont de préférence une structure à feuilles superposées comportant au moins deux, et avantageusement trois, mats de fibres et une couche de gel coat externe. The latter preferably have a structure with superimposed sheets comprising at least two, and advantageously three, fiber mats and an outer gel coat layer.
L'invention sera mieux comprise par la description qui suit, faite à titre d'exemple et en référence au dessin annexé dans lequel
- la figure 1 est une vue de face d'un élément constitutif d'un dispositif d'abri selon l'invention ;
- la figure 2 est une vue en perspective axonométrique d'un dispositif d'abri selon l'invention ;
- la figure 3 est une vue de dessus d'un tel dispositif d'abri
- la figure 4 en est une vue par l'avant;
- la figure 5 est une vue de détail, en coupe selon la ligne 5-5 de la figure 1 et à plus grande échelle, d'une partie d'élément modulaire.The invention will be better understood from the description which follows, given by way of example and with reference to the appended drawing in which
- Figure 1 is a front view of a component of a shelter device according to the invention;
- Figure 2 is an axonometric perspective view of a shelter device according to the invention;
- Figure 3 is a top view of such a shelter device
- Figure 4 is a front view;
- Figure 5 is a detail view, in section along line 5-5 of Figure 1 and on a larger scale, of a modular element part.
Un dispositif d'abri selon l'invention, figure 2, est propre à être construit par assemblage d'une pluralité d'éléments modulaires dont chacun est constitué en tant qu'une coque 10, quelque peu en forme de partie de voûte ogivale et dont la projection en plan est très sensiblement de forme carrée, comme montré en trait plein sur la figure 3. A shelter device according to the invention, FIG. 2, is suitable for being constructed by assembling a plurality of modular elements, each of which is constituted as a shell 10, somewhat in the form of part of an ogival arch and the projection of which in plan is very substantially square in shape, as shown in solid lines in FIG. 3.
De façon plus précise, un élément modulaire 10 d'un dispositif d'abri selon l'invention est sous forme d'une coque en matériau mousse de matière plastique expansée, par exemple de PVC ou de polyuréthane expansé, enfermé entre deux peaux de surface en un complexe de résine polyester armée de fibres de verre. More specifically, a modular element 10 of a shelter device according to the invention is in the form of a shell made of foam material of expanded plastic material, for example PVC or expanded polyurethane, enclosed between two surface skins in a polyester resin complex reinforced with glass fibers.
Comme bien visible sur les figures 1, 2 et 5, l'élément modulaire comprend un pied droit 11 dont la section, au voisinage de son extrémité de sol, est quelque peu en forme d'équerre, figure 5, avec, sur le dessin, une face frontale antérieure 12 et une face latérale 13 reliées l'une à l'autre par des faces 14 et 15 parallèles, respectivement, aux faces 13 et 12. Dans le plan de la face frontale antérieure le pied droit se poursuit, en direction de la clef de voûte 16, par un arc circulaire 17 centré en un point A dont la hauteur a par rapport au sol détermine la naissance de la voûte et qui est à l'aplomb de-la clef de voûte 16 dans le plan de la face 12. As clearly visible in Figures 1, 2 and 5, the modular element comprises a right foot 11 whose section, near its end of the ground, is somewhat square, Figure 5, with, in the drawing , an anterior frontal face 12 and a lateral face 13 connected to each other by faces 14 and 15 parallel, respectively, to faces 13 and 12. In the plane of the anterior frontal face the right foot continues, in direction of the keystone 16, by a circular arc 17 centered at a point A whose height a relative to the ground determines the birth of the vault and which is directly above the keystone 16 in the plane of face 12.
Il en est de même en ce qui concerne la face latérale 13 de l'élément modulaire, c'est-à-dire que, sur cette face latérale, l'élément est conformé à partir du pied 11 suivant un arc de cercle de même rayon que celui de l'arc 17, centré en un point situé dans le plan de ladite face, à l'aplomb de la clef de voûte et à une hauteur a du sol. It is the same with regard to the lateral face 13 of the modular element, that is to say that, on this lateral face, the element is shaped from the foot 11 in an arc of the same circle. radius as that of arc 17, centered at a point located in the plane of said face, directly above the keystone and at a height a from the ground.
L'intersection des parties de voûtes de la face frontale antérieure et de la face latérale, dont les extrados sont montrés en 21 et 22, se fait suivant une arête d'ogive 23. The intersection of the parts of the vaults of the anterior front face and of the lateral face, the upper surfaces of which are shown at 21 and 22, takes place along a ribbed edge 23.
L'invention prévoit d'assembler entre eux des modules tels que définis ci-dessus, accolés par leurs tranches de clef de voûte 24 et 25, figures 3 et 4, à l'aide de moyens mécaniques comme des boulons, non représentés. The invention provides for assembling together modules as defined above, joined by their keystone sections 24 and 25, Figures 3 and 4, using mechanical means such as bolts, not shown.
On obtient alors une structure à plan carré, de surface au sol quatre fois celle du plan d'un élément modulaire seul, comme montré sur la figure 3 où les éléments assemblés sont référencés 10a, 10b, 10c et 10d. This gives a structure with a square plane, with a surface area four times that of the plane of a single modular element, as shown in FIG. 3 where the assembled elements are referenced 10a, 10b, 10c and 10d.
Des trous montrés schématiquement en 30 sur la lèvre périphérique frontale ou latérale d'un élément, figure 2, permettent la liaison à l'aide de boulons de dispositifs d'abri adjacents suivant un dessin à maille carrée. Holes shown diagrammatically at 30 on the front or lateral peripheral lip of an element, FIG. 2, allow the connection by means of bolts of adjacent shelter devices in a square mesh design.
Pour ériger un dispositif d'abri selon l'invention on dispose au sol des dés en béton ou analogue dont font saillie des tiges filetées, l'on rapporte ensuite un à un les éléments modulaires 10 que l'on fixe par leur pied droit sur lesdites tiges, puis l'on rend solidaires entre eux les éléments modulaires adjacents 1osa, 1Ob, îOc et îOd. Le poids relativement faible des éléments modulaires permet leur transport sans engin de levage tandis que l'assemblage particulièrement simple, à l'aide de boulons, ne nécessite aucune main d'oeuvre spécialisée. To erect a shelter device according to the invention, concrete dice or the like are provided on the ground, from which threaded rods protrude, then one by one the modular elements 10 which are fixed by their right foot on said rods, then the adjacent modular elements 1osa, 1Ob, îOc and îOd are made integral with each other. The relatively low weight of the modular elements allows them to be transported without lifting gear, while the particularly simple assembly, using bolts, does not require any specialized labor.
Pour complèter le dispositif d'abri, l'invention prévoit, le cas échéant, des panneaux, cloisons ou parois de même constitution que celle de la coque de l'élément modulaire, c'est-à-dire des panneaux sandwich en mousse de matière plastique comme du polyuréthane ou duPVC expansé et à peaux de surface en complexe de résine polyester armée de fibres de verre, lesdits panneaux, parois ou cloisons comportant, pour certains d'entre eux, les éléments nécessaires à la formation de portes, fenêtres, supports d'appareils de climatisation, ou analogues. To complete the shelter device, the invention provides, where appropriate, panels, partitions or walls of the same constitution as that of the shell of the modular element, that is to say sandwich panels of foam plastic material such as polyurethane or expanded PVC and with surface skins in polyester resin complex reinforced with glass fibers, said panels, walls or partitions comprising, for some of them, the elements necessary for the formation of doors, windows, supports for air conditioning apparatus, or the like.
Dans une forme de réalisation ayant donné de bons résultats, et sans que ces indications aient quelque caractère limitatif que ce soit, l'élément modulaire avait un poids d'environ 60 kg et une surface au sol d'environ 4 m2. In an embodiment which has given good results, and without these indications having any limiting nature whatsoever, the modular element had a weight of approximately 60 kg and a floor area of approximately 4 m2.
Il était constitué par une âme en mousse de PVC expansé, du type vendu par la Demanderesse sous la dénomination "KLEGECELL Q 40", c'est-à-dire d'une densité de 40 kg/m3, d'une épaisseur de 40 mm recouvert sur l'intrados et l'extrados par une peau ayant une épaisseur de 2,5 mm et formée, chacune, de deux mats en résine polyester classée M1, armée de fibres de verre, d'un poids de 450 g/m2 et d'un mat en le même matériau mais d'un poids de 300 g/m2, un gel coat assurant la finition de l'ensemble.It consisted of a core of expanded PVC foam, of the type sold by the Applicant under the name "KLEGECELL Q 40", that is to say with a density of 40 kg / m3, with a thickness of 40 mm covered on the lower and upper surfaces by a skin having a thickness of 2.5 mm and each formed from two mats of polyester resin classified M1, reinforced with glass fibers, weighing 450 g / m2 and a mat of the same material but weighing 300 g / m2, a gel coat ensuring the finish of the whole.
Le rayon des arcs comme 17 était de 210 cm environ, la hauteur du module au droit de la clef de voûte de 350 cm environ, la hauteur a de la naissance de 40 cm environ, tandis que les faces comme 14 et 15 de l'équerre des pieds droits avaient une longueur d'environ 10 cm. The radius of the arches like 17 was about 210 cm, the height of the module at the right of the keystone of about 350 cm, the height at birth about 40 cm, while the faces like 14 and 15 of the right feet square had a length of about 10 cm.
Avec un tel élément, l'isolation thermique est excellente (coefficient = 0,026 W/m K), ce qui est d'importance pour des pays à climat tropical, ou désertique, dans lesquels le dispositif selon l'invention peut trouver une application particulièrement satisfaisante. With such an element, the thermal insulation is excellent (coefficient = 0.026 W / m K), which is of importance for countries with tropical or desert climate, in which the device according to the invention can find a particularly application. satisfactory.
En outre, l'utilisation d'une résine du type de celle mentionnée ci-dessus permet de satisfaire aux normes de sécurité en ce qui concerne la résistance au feu. In addition, the use of a resin of the type mentioned above makes it possible to meet safety standards with regard to fire resistance.
La simplicité d'assemblage du dispositif selon l'invention permet, par l'assemblage entre eux de quatre modules tels que décrits ci-dessus, de couvrir en moins d'une heure une surface au sol de l'ordre de 16 m2 par un abri ayant sensiblement 4 m de côté et 3,5 m de hauteur. The simplicity of assembly of the device according to the invention allows, by assembling together four modules as described above, to cover in less than an hour a floor area of the order of 16 m2 by a shelter having substantially 4 m side and 3.5 m height.
Le dispositif d'abri selon l'invention peut aisément s'intégrer à l'environnement en donnant aux couches de gel coat externes la ou les teintes souhaitées. The shelter device according to the invention can easily be integrated into the environment by giving the external gel coat layers the desired shade (s).
