Description

La présente invention concerne un abri technique mobile destiné à contenir du matériel et/ou du personnel, notamment militaire, de forme parallélépipédique et de dimensions telles qu'il puisse être transporté sur des véhicules terrestres, maritimes ou aériens.The present invention relates to a mobile technical shelter intended to contain equipment and / or personnel, in particular military, of rectangular shape and of dimensions such that it can be transported on land, sea or air vehicles.

De tels abris sont communément appelés "shelters" ou ATM.Such shelters are commonly called "shelters" or ATM.

L'invention vise également le procédé de fabrication de certains éléments des abris techniques précités.The invention also relates to the method of manufacturing certain elements of the aforementioned technical shelters.

Ces abris présentent une hauteur suffisante pour permettre la station debout du personnel, en leur intérieur. Leur longueur varie entre trois et six mètres environ.These shelters have a sufficient height to allow the standing station of the personnel, inside them. Their length varies between three and six meters approximately.

Ces abris doivent être le plus léger possible pour qu'ils puissent, lorsqu'ils sont munis de leur chargement interne, être soulevés facilement avec les moyens de levage couramment utilisés dans l'armée.These shelters must be as light as possible so that they can, when provided with their internal load, be easily lifted with the lifting means commonly used in the army.

Parmi les sollicitations auxquelles ces abris peuvent être soumis, il faut citer celles inhérentes à l'explosion d'une charge nucléaire dont les effets sont principalement l'émission d'impulsions électromagnétiques et un souffle de 30KPa.Among the stresses to which these shelters may be subjected, we must cite those inherent in the explosion of a nuclear charge, the effects of which are mainly the emission of electromagnetic pulses and a blast of 30KPa.

Les abris de ce type sont actuellement constitués par un cadre ou ossature métallique, comprenant des profilés assemblés entre eux, sur lequel sont fixés des panneaux à peaux métalliques et âme thermiquement isolante.Shelters of this type are currently constituted by a metal frame or framework, comprising profiles assembled together, on which are fixed panels with metal skins and thermally insulating core.

Le cadre ou ossature métallique ci-dessus assure une bonne rigidité à l'ensemble. Toutefois, ce cadre alourdit considérablement l'abri, complique l'assemblage de ce dernier et rend celui-ci relativement coûteux à fabriquer et à transporter.The above frame or metal frame ensures good rigidity to the whole. However, this frame considerably increases the shelter, complicates the assembly of the latter and makes it relatively expensive to manufacture and transport.

Le but de la présente invention est de remédier aux inconvénients ci-dessus, en créant un abri qui soit à la fois plus léger, plus rigide, plus facile à assembler et plus performant que les abris connus.The object of the present invention is to remedy the above drawbacks, by creating a shelter which is both lighter, more rigid, easier to assemble and more efficient than known shelters.

Suivant l'invention, l'abri technique mobile destiné à contenir du matériel et/ou du personnel, notamment militaire, de forme parallélépipédique et de dimensions telles qu'il puisse être transporté sur des véhicules terrestres, maritime ou aérien, est caractérisé en ce qu'il est constitué par des panneaux assemblés les uns aux autres par des éléments de section transversale arquée formant les arêtes du parallélépipède, lesdits panneaux et lesdits éléments étant constitués chacun par deux tôles métalliques séparées par une mousse en matière plastique collée à ces deux tôles, l'assemblage par soudage des tôles de ces panneaux et de ces éléments assurant directement la rigidité de l'abri, sans cadre ou structure de renforcement.According to the invention, the mobile technical shelter intended to contain equipment and / or personnel, in particular military, of rectangular shape and of dimensions such that it can be transported on land, sea or air vehicles, is characterized in that that it consists of panels assembled to each other by elements of arcuate cross section forming the edges of the parallelepiped, said panels and said elements each being constituted by two metal sheets separated by a plastic foam bonded to these two sheets , the assembly by welding of the sheets of these panels and of these elements directly ensuring the rigidity of the shelter, without frame or reinforcing structure.

Ainsi, l'abri technique selon l'invention est dépourvu de cadre métallique, ce qui le rend facile et peu coûteux à assembler.Thus, the technical shelter according to the invention does not have a metal frame, which makes it easy and inexpensive to assemble.

Par ailleurs, en l'absence de montants et de poutres, l'abri selon l'invention est léger donc facile à transporter, car il est exclusivement réalisé à partir de minces tôles métalliques et d'une mousse en matière plastique.Furthermore, in the absence of uprights and beams, the shelter according to the invention is light and therefore easy to transport, since it is exclusively made from thin metal sheets and a plastic foam.

Toutefois, l'abri conforme à l'invention présente grâce à sa structure, une certaine souplesse qui lui permet de résister notamment à des souffles engendrant sur sa surface extérieure des pressions dépassant 30 KPa.However, the shelter according to the invention has, thanks to its structure, a certain flexibility which enables it to withstand in particular breaths generating on its outer surface pressures exceeding 30 KPa.

Selon une version avantageuse de l'invention, les tôles des panneaux et éléments sont en aluminium d'épaisseur comprise entre 1 et 2 mm environ.According to an advantageous version of the invention, the sheets of the panels and elements are made of aluminum with a thickness of between 1 and 2 mm approximately.

De telles tôles en aluminium permettent de réaliser une structure légère et sont facilement pliables pour réaliser les éléments d'angle de section arquée.Such aluminum sheets make it possible to produce a light structure and are easily foldable to produce the corner elements of arcuate section.

Selon une version préférée de l'invention, la mousse de matière plastique est une mousse de PVC (polychlorure de vinyle).According to a preferred version of the invention, the plastic foam is PVC (polyvinyl chloride) foam.

Cette mousse est facilement thermoformable et collable, absorbe les pressions dues au souffle d'une explosion atomique et procure une excellente isolation thermique, sans aucun pont thermique puisqu'elle s'étend sans discontinuité entre les tôles formant les faces extérieure et intérieure de l'abri.This foam is easily thermoformable and stickable, absorbs the pressures due to the breath of an atomic explosion and provides excellent thermal insulation, without any thermal bridge since it extends without discontinuity between the sheets forming the outer and inner faces of the shelter.

Selon un autre aspect de l'invention, le procédé de fabrication des éléments de section arquée de l'abri technique conforme à l'invention, est caractérisé en ce qu'il comprend les étapes suivantes :

  • a) on chauffe une plaque de mousse à une température suffisante pour la rendre apte au thermoformage,
  • b) on place la plaque de mousse dans un moule de thermoformage,
  • c) on incurve la plaque de mousse suivant le profil du moule sous l'action d'une pression exercée sur la face supérieure de la plaque et d'une dépression réalisée sous la face inférieure de cette plaque,
  • d) on place la plaque de mousse thermoformée entre deux tôles dont les faces adjacentes à la mousse sont enduites d'une couche de colle,
  • e) on place l'ensemble ci-dessus sur une forme et on presse l'ensemble sur cette forme.
According to another aspect of the invention, the method of manufacturing the arcuate section elements of the technical shelter according to the invention, is characterized in that it comprises the following steps:
  • a) a foam plate is heated to a temperature sufficient to make it suitable for thermoforming,
  • b) the foam plate is placed in a thermoforming mold,
  • c) the foam plate is curved according to the profile of the mold under the action of a pressure exerted on the upper face of the plate and of a depression produced under the lower face of this plate,
  • d) the thermoformed foam plate is placed between two sheets, the faces adjacent to the foam are coated with a layer of adhesive,
  • e) the above assembly is placed on a form and the assembly is pressed on this form.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

Dans les réalisations des figures 1A, 1B, 2, 3, 4A, 4B, l'abri technique mobile, destiné à contenir du matériel par exemple électronique ou médical et/ou du personnel, notamment militaire, présente une forme parallélépipédique.In the embodiments of FIGS. 1A, 1B, 2, 3, 4A, 4B, the mobile technical shelter, intended to contain equipment, for example electronic or medical, and / or personnel, in particular military personnel, has a parallelepiped shape.

Sa longueur est par exemple comprise entre trois et six mètres, et sa hauteur et largeur de l'ordre de 2 à 2,50 mètres.Its length is for example between three and six meters, and its height and width of the order of 2 to 2.50 meters.

Il présente ainsi les dimensions habituelles des conteneurs qui peuvent être chargés et transportés sur des camions, des navires ou dans des avions, civils ou militaires.It thus presents the usual dimensions of containers which can be loaded and transported on trucks, ships or in planes, civil or military.

L'abri représenté sur les figures 1A, 1B, 2, 3, 4A, 48 est constitué par des panneaux 1, 2, 3, 4 assemblés les uns aux autres suivant les arêtes du volume parallélépipédique.The shelter shown in Figures 1A, 1B, 2, 3, 4A, 48 is constituted by panels 1, 2, 3, 4 assembled to each other along the edges of the parallelepiped volume.

Le panneau 1 constitue le plancher, le panneau 2 constitue l'une des deux parois latérales s'étendant suivant la longueur de l'abri, le panneau 3 constitue l'une des deux parois latérales s'étendant suivant la largeur de l'abri et qui comprend la porte 5, et le panneau 4 constitue le plafond.The panel 1 constitutes the floor, the panel 2 constitutes one of the two side walls extending along the length of the shelter, the panel 3 constitutes one of the two side walls extending along the width of the shelter and which includes the door 5, and the panel 4 constitutes the ceiling.

Conformément à l'invention, aucun cadre métallique, c'est-à-dire aucun montant ni aucune poutre, ne sont prévus pour assurer la rigidité de l'abri, celle-ci étant déterminée uniquement par les panneaux 1, 2, 3, 4 eux-mêmes et leurs moyens d'assemblage suivant les arêtes du parallélépipède.In accordance with the invention, no metal frame, that is to say no upright or any beam, are not provided to ensure the rigidity of the shelter, the latter being determined only by the panels 1, 2, 3, 4 themselves and their means of assembly along the edges of the parallelepiped.

Conformément à une caractéristique essentielle de l'invention, les panneaux 2, 3, 4 sont assemblés les uns aux autres par des éléments tels que 6, 7, 8 de section transversale arquée formant les arêtes du parallélépipède.In accordance with an essential characteristic of the invention, the panels 2, 3, 4 are assembled to each other by elements such as 6, 7, 8 of arcuate cross section forming the edges of the parallelepiped.

Les panneaux 2 et 3 ainsi que les deux autres panneaux latéraux (non représentés sur les figures 1 à 4) sont assemblés au plancher 1 par des moyens différents des éléments de section arquée, qui seront décrits plus loin.The panels 2 and 3 as well as the other two side panels (not shown in Figures 1 to 4) are assembled to the floor 1 by means different from the elements of arcuate section, which will be described later.

Les figures 1A, 1B, 2, 3, 4A, 4B illustrent plusieurs variantes de montage de l'abri à partir de panneaux individuels. Toutefois, la structure finale de ces différents abris est identique.Figures 1A, 1B, 2, 3, 4A, 4B illustrate several variants of mounting the shelter from individual panels. However, the final structure of these various shelters is identical.

La figure 1 montre que l'élément arqué 7 est solidaire du panneau 4 jouant le rôle de plafond, que l'élément arqué 6 est solidaire du panneau 2, tandis que l'élément arqué 8 est solidaire du panneau 3. La figure 1B illustre une variante selon laquelle le panneau 3 est plan, l'élément arqué 8 étant solidaire du panneau 2 et les éléments arqués 6 et 7 du panneau de toit 4. Dans la variante selon la figure 2, les éléments arqués 7 et 8 sont solidaires du panneau 3, le panneau 4 étant alors parfaitement plan. Selon la figure 3, le panneau 5 est plan ; le panneau 2 comporte les éléments arqués 6 et 8, le panneau de l'élément arqué 7, tandis que le panneau 3 est parfaitement plan. Dans le mode de réalisation suivant la figure 4A, tous les panneaux sont plans, les éléments arqués 6, 7 et 8 étant réalisés individuellement. La figure 4B montre une variante de réalisation de l'abri selon l'invention, dans laquelle les éléments arqués 7 et 8 sont supprimés, les panneaux 2 et 3 d'une part et 3 et 4 d'autre part étant directement liés entre eux. L'élément arqué est alors solidaire du panneau de toit 4 et assure la jonction avec les panneaux 2 et 3. Cet élément présente une partie plane 45 prolongée par deux parties courbes 46 et 47 visibles sur la figure 5B. On voit donc que la forme des éléments arqués est quelconque pourvu qu'ils assurent la jonction entre deux panneaux adjacents.Figure 1 shows that the arched element 7 is secured to the panel 4 playing the role of ceiling, that the arched element 6 is secured to the panel 2, while the arched element 8 is secured to the panel 3. Figure 1B illustrates a variant according to which the panel 3 is planar, the arched element 8 being integral with the panel 2 and the arched elements 6 and 7 of the roof panel 4. In the variant according to FIG. 2, the arched elements 7 and 8 are integral with the panel 3, the panel 4 then being perfectly flat. According to Figure 3, the panel 5 is planar; the panel 2 comprises the arcuate elements 6 and 8, the panel of the arcuate element 7, while the panel 3 is perfectly flat. In the embodiment according to FIG. 4A, all the panels are planar, the arcuate elements 6, 7 and 8 being produced individually. FIG. 4B shows an alternative embodiment of the shelter according to the invention, in which the arched elements 7 and 8 are removed, the panels 2 and 3 on the one hand and 3 and 4 on the other hand being directly linked together. The arched element is then secured to the roof panel 4 and provides the junction with the panels 2 and 3. This element has a flat part 45 extended by two curved parts 46 and 47 visible in FIG. 5B. It can therefore be seen that the shape of the arcuate elements is arbitrary provided that they provide the junction between two adjacent panels.

On voit sur les figures 5, 6 et 7 que les panneaux 1, 4 et 9 formant respectivement le plancher, le plafond et l'une des quatre parois latérales, sont constitués chacun par deux tôles métalliques 10, 11 séparées par une mousse de matière plastique 12 dont les deux faces sont collées aux deux tôles 10, 11.We see in Figures 5, 6 and 7 that the panels 1, 4 and 9 respectively forming the floor, the ceiling and one of the four side walls, each consist of two metal sheets 10, 11 separated by a foam material plastic 12, the two faces of which are glued to the two sheets 10, 11.

De même, les éléments de section arquée tels que 7, 7a qui relient respectivement le panneau latéral 9 au plafond 4 et le panneau 3 de la porte 5 au plafond 4 sont constitués chacun par deux tôles métalliques 13, 14 séparées par une mousse de matière plastique 12 collée à ces deux tôles.Similarly, the elements of arcuate section such as 7, 7a which respectively connect the side panel 9 to the ceiling 4 and the panel 3 of the door 5 to the ceiling 4 are each constituted by two metal sheets 13, 14 separated by a foam of material plastic 12 bonded to these two sheets.

La tôle extérieure 10 des panneaux tels que 9 et 4 est relié par des soudures continues qui seront détaillées plus loin à la tôle extérieure 13 des éléments de section arquée 7, 7a.The outer sheet 10 of the panels such as 9 and 4 is connected by continuous welds which will be detailed later on the outer sheet 13 of the arcuate section elements 7, 7a.

D'autres moyens d'assemblage qui sont détaillés plus loin sont prévus pour relier les tôles intérieures des panneaux et les éléments de section arquée.Other assembly means which are detailed below are provided for connecting the internal sheets of the panels and the elements of arcuate section.

Les tôles des panneaux et éléments sont de préférence en aluminium d'épaisseur comprise entre 1 et 2 mm environ.The sheets of the panels and elements are preferably made of aluminum with a thickness of between 1 and 2 mm approximately.

La mousse de matière plastique 12 est de préférence une mousse de PVC (polychlorure de vinyle), l'épaisseur de cette mousse étant préférablement comprise entre 50 et 60 mm environ.The plastic foam 12 is preferably a PVC foam (polyvinyl chloride), the thickness of this foam preferably being between 50 and 60 mm approximately.

De préférence également, la mousse 12 comprise entre les tôles 10, 11 d'un panneau tel que 4 ou 9 est collée à ses extrémités à la mousse 12 des éléments arqués adjacents tels que 7, 7a. On obtient ainsi une parfaite continuité de la mousse entre les différents panneaux.Also preferably, the foam 12 between the sheets 10, 11 of a panel such as 4 or 9 is glued at its ends to the foam 12 of the adjacent arcuate elements such as 7, 7a. This gives perfect continuity of the foam between the different panels.

On voit notamment sur la figure 8 que la tôle 13 située à l'extérieur d'un élément de section arquée tel que 7a s'étend au-delà des extrémités opposées 12a, 12b de la mousse 12 et recouvre sur une certaine distance, les panneaux adjacents 4, 9.It can be seen in particular in FIG. 8 that the sheet 13 located outside of an element of arcuate section such as 7a extends beyond the opposite ends 12a, 12b of the foam 12 and covers over a certain distance, the adjacent panels 4, 9.

Les soudures continues 15, 15a qui relient les tôles extérieures 10 des panneaux et la tôle extérieure 13 de l'élément de section arquée 7a sont de ce fait situées au droit de la mousse 12 des panneaux.The continuous welds 15, 15a which connect the outer sheets 10 of the panels and the outer sheet 13 of the arcuate section element 7a are therefore located in line with the foam 12 of the panels.

On voit également, notamment sur la figure 8, que l'élément de section arquée est courbé suivant un arc de cercle de 90° dont le rayon extérieur est de l'ordre de 100 à 150 mm. Par ailleurs, les faces d'extrémité 12a, 12b de la mousse sont perpendiculaires entre elles de sorte qu'elles s'ajustent parfaitement contre les faces d'extrémités de la mousse des panneaux 4, 9.It can also be seen, in particular in FIG. 8, that the arcuate section element is curved according to an arc of a circle of 90 ° whose outside radius is of the order of 100 to 150 mm. Furthermore, the end faces 12a, 12b of the foam are perpendicular to each other so that they fit perfectly against the end faces of the foam of the panels 4, 9.

Par ailleurs, dans l'exemple représenté sur la figure 8, la mousse 12 des éléments de section arquée tels que 7a est en PVC linéaire de densité égale à environ 90 kg/m³ et la mousse des panneaux tels que 4, 9 est en PVC réticulé de densité égale à environ 55 kg/m³. Cette particularité résulte du procédé de formage qui sera décrit plus loin.Furthermore, in the example shown in FIG. 8, the foam 12 of the elements of arcuate section such as 7a is made of linear PVC of density equal to approximately 90 kg / m³ and the foam of the panels such as 4, 9 is made of PVC crosslinked with a density of approximately 55 kg / m³. This feature results from the forming process which will be described later.

Par ailleurs, dans les panneaux 4, 9, la mousse 12c située à la périphérie est en PVC linéaire, de sorte qu'elle est en contact avec une mousse de même qualité des éléments arqués tels que 7a, ce qui facilite le collage des extrémités adjacentes de la mousse.Furthermore, in the panels 4, 9, the foam 12c situated at the periphery is made of linear PVC, so that it is in contact with a foam of the same quality of the arcuate elements such as 7a, which facilitates the bonding of the ends. adjacent to the foam.

D'autre part, dans l'exemple représenté à la figure 8, chaque élément de section arquée tel que 7a comprend entre la tôle extérieure 13 et la mousse 12 une couche de bois 16 par exemple en contreplaqué d'épaisseur égale à 3 mm.On the other hand, in the example represented in FIG. 8, each element of arcuate section such as 7a comprises between the external sheet 13 and the foam 12 a layer of wood 16 for example of plywood of thickness equal to 3 mm.

De plus, une couche de bois 16a est également prévue à la périphérie des panneaux 4, 9, de telle sorte que cette couche de bois 16a soit située sous la soudure 15, 15a réalisée entre les tôles extérieures 13, 10 des éléments arrondis et des panneaux.In addition, a layer of wood 16a is also provided at the periphery of the panels 4, 9, so that this layer of wood 16a is located under the weld 15, 15a produced between the outer sheets 13, 10 of the rounded elements and panels.

Ces couches de bois 16, 16a permettent de protéger la mousse lors du soudage des tôles et de répartir les efforts.These layers of wood 16, 16a make it possible to protect the foam when welding the sheets and to distribute the forces.

Comme indiqué notamment sur la figure 6, les panneaux latéraux tels que 9 sont assemblés à angle droit avec le plancher 1 de l'abri au moyen de profilés extérieur 17 et intérieur 18 en aluminium, sensiblement en forme d'équerre.As indicated in particular in FIG. 6, the side panels such as 9 are assembled at right angles to the floor 1 of the shelter by means of external 17 and internal 18 aluminum profiles, substantially in the form of a square.

Les ailes 17a, 17b du profilé extérieur 17 sont soudées respectivement à la tôle extérieure 10 du panneau latéral 9 et celle du plancher 1.The wings 17a, 17b of the external profile 17 are welded respectively to the external sheet 10 of the side panel 9 and that of the floor 1.

De plus, ce profilé extérieur 17 comprend une partie tubulaire 17c de laquelle font saillie les ailes 17a, 17b du profilé. Cette partie tubulaire 17c comporte deux méplats 17d, 17e perpendiculaires formant butées respectivement pour l'extrémité inférieure du panneau latéral 9 et l'extrémité du plancher 1.In addition, this external profile 17 comprises a tubular part 17c from which the wings 17a, 17b of the profile project. This tubular part 17c has two perpendicular flats 17d, 17e forming stops respectively for the lower end of the side panel 9 and the end of the floor 1.

L'équerre intérieure 18 est fixée au moyen de vis (non représentées) aux tôles intérieures 11 du panneau 9 et du plancher 1.The internal bracket 18 is fixed by means of screws (not shown) to the internal sheets 11 of the panel 9 and of the floor 1.

Par ailleurs, les tôles intérieures 11 des panneaux 9 et 4 sont reliées à la tôle intérieure 14 de l'élément de section arquée 7a au moyen d'éléments de fixation 19, 20 fixés aux tôles par des rivets.Furthermore, the internal sheets 11 of the panels 9 and 4 are connected to the internal sheet 14 of the arcuate section element 7a by means of fastening elements 19, 20 fixed to the sheets by rivets.

Dans la réalisation représentée aux figures 5 et 7, l'abri comprend une cloison 21 qui est également constituée par deux tôles d'aluminium 22, 23 entre lesquelles est disposée une mousse 24 en PVC.In the embodiment shown in Figures 5 and 7, the shelter comprises a partition 21 which is also constituted by two aluminum sheets 22, 23 between which is disposed a PVC foam 24.

Cette cloison 21 est fixée au plafond 4 et au plancher 1 par des éléments de fixation en forme d'équerre 25, 26, 27, 28.This partition 21 is fixed to the ceiling 4 and to the floor 1 by shaped fixing elements. square 25, 26, 27, 28.

On va maintenant décrire en référence aux figures 9 à 16, le procédé de fabrication des éléments de section arquée tels que 7, 7a de l'abri technique conforme à l'invention.We will now describe, with reference to FIGS. 9 to 16, the method of manufacturing elements of arcuate section such as 7, 7a of the technical shelter according to the invention.

Ce procédé comprend les étapes suivantes :This process includes the following steps:

Dans une première étape, on chauffe une plaque de mousse rectangulaire 30 à une température suffisante pour la rendre apte au thermoformage. Cette température est de l'ordre de 115°C dans le cas d'une mousse en PVC.In a first step, a rectangular foam plate 30 is heated to a temperature sufficient to make it suitable for thermoforming. This temperature is around 115 ° C in the case of PVC foam.

Immédiatement après ce chauffage, on place la plaque de mousse 30 sur un moule de thermoformage 31 présentant (voir figure 9) une cavité 32 dont la forme intérieure correspond à la courbure finale que l'on veut obtenir.Immediately after this heating, the foam plate 30 is placed on a thermoforming mold 31 having (see FIG. 9) a cavity 32 whose internal shape corresponds to the final curvature which it is desired to obtain.

On incurve la plaque de mousse 30 suivant le profil de la cavité 32 du moule sous l'action d'une pression exercée sur la face supérieure de la plaque 30 et d'une dépression réalisée sous la face inférieure de cette plaque.The foam plate 30 is curved along the profile of the cavity 32 of the mold under the action of a pressure exerted on the upper face of the plate 30 and of a depression produced under the lower face of this plate.

La pression est exercée sur la face supérieure de la mousse au moyen d'un dispositif de formage 33 articulé en 37 sur l'un des côtés du moule 31. Ce dispositif 33 comprend un bloc central 34 et deux blocs latéraux 35, 36 destinés à venir en appui sur la mousse (voir figures 10, 11, 12). Le bloc 36 qui s'appuie sur la mousse 30 en premier, bloque celle-ci près du côté adjacent à l'articulation 37.The pressure is exerted on the upper face of the foam by means of a forming device 33 articulated at 37 on one of the sides of the mold 31. This device 33 comprises a central block 34 and two lateral blocks 35, 36 intended for come to rest on the foam (see figures 10, 11, 12). The block 36 which rests on the foam 30 first, blocks it near the side adjacent to the joint 37.

Le bloc central 34 qui s'appuie au milieu de la mousse incurve celle-ci vers le fond de la cavité 32.The central block 34 which rests in the middle of the foam curves it towards the bottom of the cavity 32.

L'autre bloc latéral 35 s'appuie sur le côté de la mousse opposé à l'articulation 37.The other lateral block 35 rests on the side of the foam opposite the articulation 37.

La dépression réalisée au fond de la cavité 32 par un canal d'aspiration 38 permet de parfaire la courbure de la mousse.The depression produced at the bottom of the cavity 32 by a suction channel 38 makes it possible to perfect the curvature of the foam.

En fin d'opération, on découpe les extrémités de la mousse suivant les lignes pointillées 39, 40 représentées à la figure 13.At the end of the operation, cut the ends foam along the dotted lines 39, 40 shown in FIG. 13.

Compte tenu de l'épaisseur désirée de la mousse, il peut être nécessaire de disposer dans les éléments de section arquée 7, 7a ainsi que dans les panneaux, deux couches de mousse, collées entre elles.Given the desired thickness of the foam, it may be necessary to have in the elements of arcuate section 7, 7a and in the panels, two layers of foam, bonded together.

Ainsi, pour chaque élément 7, 7a, il sera nécessaire de thermoformer deux plaques de mousse.Thus, for each element 7, 7a, it will be necessary to thermoform two foam plates.

Dans une étape ultérieure montrée à la figure 14, on place les deux plaques de mousse 30 et 30a thermoformées entre deux tôles 41, 41a, la première recouvrant une plaque de contreplaqué 42, dont les faces adjacentes à la mousse, sont enduites d'une couche de colle, telle qu'une colle époxy.In a subsequent step shown in FIG. 14, the two thermoformed foam plates 30 and 30a are placed between two sheets 41, 41a, the first covering a plywood plate 42, the faces of which are adjacent to the foam, are coated with a layer of glue, such as epoxy glue.

On place ensuite l'ensemble ci-dessus sur une forme 43 (voir figure 15) et on presse l'ensemble sur cette forme en appliquant sur la tôle extérieure 41 une pression uniformément répartie.The above assembly is then placed on a form 43 (see FIG. 15) and the assembly is pressed on this form by applying to the outer sheet 41 a uniformly distributed pressure.

Pour limiter l'écrasement de l'ensemble, des butées 44, solidaires de la forme 43, sont prévues de part et d'autre des deux couches de mousse 30, 30a.To limit the crushing of the assembly, stops 44, integral with the form 43, are provided on either side of the two layers of foam 30, 30a.

La figure 16 montre le résultat final obtenuFigure 16 shows the final result

Les principaux avantages de l'abri technique mobile selon l'invention sont les suivants.The main advantages of the mobile technical shelter according to the invention are as follows.

Le poids de cet abri est nettement plus faible que celui des réalisations connues grâce :

  • à l'absence de cadre rigide, et
  • à l'utilisation exclusive de tôles minces en aluminium et de mousse de matière plastique.
The weight of this shelter is significantly lower than that of the known constructions thanks to:
  • the absence of a rigid frame, and
  • for the exclusive use of thin aluminum sheets and plastic foam.

Cet abri résiste néanmoins aux pressions engendrées par le souffle d'une explosion atomique. Cette résistance est due notamment aux raccordements entre les panneaux par des éléments de section arquée et à la résistance mécanique du panneau composite dont l'âme est de la mousse de PVC.This shelter nevertheless resists the pressures generated by the breath of an atomic explosion. This resistance is due in particular to the connections between the panels by elements of arcuate section and to the mechanical resistance of the composite panel whose core is PVC foam.

L'abri est totalement imperméable à l'égard des rayonnements, des gaz et agents biologiques, grâce aux soudures continues utilisées pour assembler les tôles extérieures des divers éléments de l'abri. Cette imperméabilité est complétée par les couches de colle qui relient les tôles et la mousse.The shelter is completely impermeable to radiation, gases and biological agents, thanks to the continuous welds used to assemble the external sheets of the various elements of the shelter. This impermeability is supplemented by the layers of glue which connect the sheets and the foam.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation que l'on vient de décrire et on peut apporter à ceux-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and many modifications can be made to them without departing from the scope of the invention.
