Definitions

  • the present invention relates to a mobile technical shelter intended to contain equipment and / or personnel, in particular military, of rectangular shape and dimensions such that it can be transported on land, sea or air vehicles.
  • Such shelters are commonly called “shelters” or ATM.
  • the invention also relates to the method of manufacturing certain elements of the aforementioned technical shelters.
  • 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.
  • 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.
  • the object of the present invention is to design a shelter which is at the same time lighter, more rigid, easier to assemble and more efficient than known shelters.
  • the invention provides a mobile 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, this shelter being consisting of a floor panel, side panels and a ceiling panel, at least two opposite side panels and the ceiling panel being assembled by elements of arcuate cross section forming edges of the parallelepiped, said side and ceiling panels and said elements arched, each consisting of two rigid external and internal walls separated by a layer of plastic foam glued to the two walls, characterized in that the mobile shelter is a technical shelter and in that the walls of each panel and of each element arched consist of metal sheets, in that at least the external walls of the pannels lateral waters and ceiling and the external walls of the adjacent arched elements are welded together along their adjacent edges, and in that the arched elements comprise a layer of wood between their external wall and their layer of foam to obtain a better distribution of the forces after assembly, the assembly by welding of the sheets of these panels and of these elements directly ensuring the rigidity of the shelter,
  • the external wall of the arcuate elements extends beyond the opposite ends of the layer of foam and covers over a certain length the adjacent side or ceiling panels.
  • each side and ceiling panel comprises, at its periphery, a layer of wood between its outer wall and its layer of foam, so that this layer of wood is located under the welds made between the side and ceiling panels and the adjacent arched elements.
  • the technical shelter according to the invention is devoid of a metal frame, which makes it easy and inexpensive to assemble.
  • 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.
  • 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.
  • the sheets of the panels and elements are made of aluminum with a thickness of between 1 and 2 mm approximately.
  • Such aluminum sheets make it possible to produce a light structure and are easily foldable to produce the corner elements of arcuate section.
  • the plastic foam is PVC foam (polyvinyl chloride).
  • 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.
  • the mobile technical shelter intended to contain equipment, for example electronic or medical and / or personnel, in particular military personnel, has a parallelepiped shape.
  • Its length is for example between three and six meters, and its height and width of the order of 2 to 2.50 meters.
  • the shelter shown in FIGS. 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.
  • 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
  • the panel 4 constitutes the ceiling.
  • 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.
  • 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.
  • the panels 2 and 3 as well as the two other side panels are assembled to the floor 1 by means different from the elements of arcuate section, which will be described later.
  • FIGS 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.
  • FIG. 1A shows that the arched element 7 is integral with the panel 4 playing the role of a ceiling, that the arched element 6 is integral with the panel 2, while the arched element 8 is integral with the panel 3.
  • FIG. 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.
  • the arched elements 7 and 8 are integral with the panel 3, the panel 4 then being perfectly flat.
  • the panel 5 is planar; the panel 2 comprises the arched elements 6 and 8, the roof panel 4 comprises the arched element 7, while the panel 3 is perfectly flat.
  • 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 arched elements is arbitrary provided that they provide the junction between two adjacent panels.
  • 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 bonded to the two sheets 10, 11.
  • 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.
  • the outer sheet 10 of the panels such as 9 and 4 is connected by continuous welds which will be detailed below to the outer sheet 13 of the arcuate section elements 7, 7a.
  • the sheets of the panels and elements are preferably made of aluminum with a thickness of between 1 and 2 mm approximately.
  • the plastic foam 12 is preferably a PVC foam (polyvinyl chloride), the thickness of this foam preferably being between 50 and 60 mm approximately.
  • 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.
  • the continuous welds 15 which connect the outer sheets 10 of the panels and the outer sheet 13 of the arcuate section member 7a are therefore located in line with the foam 12 of the panels.
  • the arcuate section element is curved in an arc of a 90 ° circle whose outside radius is of the order of 100 to 150 mm.
  • 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.
  • 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 12 of the panels such as 4, 9 is in Crosslinked PVC with a density of approximately 55 kg / m3. This feature results from the forming process which will be described later.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

  • This partition 21 is fixed to the ceiling 4 and to the floor 1 by shaped fixing elements. square 25, 26, 27, 28.
  • This process includes the following steps:
  • 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.
  • 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.
  • 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.
  • 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.
  • the central block 34 which rests in the middle of the foam curves it towards the bottom of the cavity 32.
