Description

Title of the invention: Transportable prefabricated housing module Technical field

[0001] The present invention relates generally to transportable prefabricated housing modules, intended to respond to emergency situations or temporary needs.

[0002] It relates in particular to such a housing module capable of being stored and transported with an optimized footprint and then mounted at the location where it is to be used. Prior art

[0003] In emergency situations requiring the temporary reception of a large number of refugees who are victims of armed conflicts or natural disasters (floods, earthquakes, fires, etc.) as well as to respond to health crises requiring the creation of priority containment zones and / or field hospitals, so-called "military" tents are traditionally used for rapid deployment, which can be erected and installed in large numbers.

[0004] Whether they have a frame structure, stretched canvas, inflatable or raised, these military tents do not, however, provide an acceptable level of comfort to the populations they accommodate over the long term, particularly when the external climatic conditions are difficult (insufficient insulation from heat and cold, high sensitivity to wind and dust, water infiltration, etc.).

[0005] In order to improve comfort, it is known to install prefabricated rigid modules of the type marketed for example by the company Algeco®

[0006] Equipped with a metal structure and presenting a parallelepiped shape suitable for their transport by truck or rail wagon, these modules also have the advantage of being able to be easily coupled to each other in a modular manner.

[0007] Unfortunately, the transport costs of these prefabricated rigid modules are particularly high, which does not allow their deployment over long distances, whether by sea, land or air. In addition, the storage costs of these modules when not in use are particularly expensive due to the volume they occupy.

[0008] Also known, in particular from international patent application WO 1991 / 002869 A1, is a prefabricated rigid housing module comprising a floor panel, a roof panel, and two longitudinal side panels each consisting of two rigid lower and upper half-panels pivotally articulated by two of their longitudinal edges, the second longitudinal edge of each said lower half-panel, respectively upper, being pivotally articulated on a corresponding longitudinal side of the floor panel, respectively roof panel.

[0009] The longitudinal side panels are thus able to move, when said roof panel is raised, from a horizontally retracted position in which their half-panels are folded inwards onto each other to a raised position in which the latter extend vertically in line with each other between said floor and roof panels.

[0010] The housing module also comprises two rigid transverse end side panels each pivotally hinged by their lower edge on a corresponding end edge of the floor panel, so as to be able to be pivoted between a horizontally retracted position and a raised position in which they extend vertically between said floor and roof panels.

[0011] Such a housing module can thus adopt a compact transport configuration in which the longitudinal and transverse end side panels are folded horizontally on top of each other between the floor and roof panels.

[0012] In such a compact configuration, the module has a parallelepiped volume barely greater than the sum of the volumes of the rigid panels which constitute it, which makes it possible to considerably reduce storage and transport costs.

[0013] A large number of such modules can thus be housed in containers and transported by sea, land and / or air over very long distances.

[0014] However, once deployed on site, these modules have a limited habitable surface area (around 13 to 14 m2) due to their small width imposed by the internal dimensions of the containers or transport platforms.

[0015] Furthermore, unlike Algeco® type modules, these foldable modules do not offer the same modularity possibilities for increasing the habitable floor space. For structural reasons, they can only be juxtaposed by their ends, which is of little interest from a habitability point of view (corridor effect). Statement of the invention

[0016] The present invention therefore aims to improve the situation.

[0017] For this purpose, it offers a transportable prefabricated housing module comprising: - a rectangular floor panel intended to extend horizontally on a level floor or on supporting means, - a rectangular roof panel designed to extend horizontally to the above and the gap of said floor panel, - two longitudinal side panels of rectangular shape intended to extend vertically between and along the corresponding longitudinal edges of said floor and roof panels, and - two transverse side panels of rectangular shape, intended to extend vertically between and along the corresponding transverse edges of said floor and roof panels; characterized in that said floor panel and said roof panel are each made up of two rigid rectangular half-panels of the same dimensions pivotally hinged by two of their longitudinal edges, so as to be foldable in two lengthwise, and in that said module is capable of occupying a transport configuration in which said floor and roof panels are folded by being placed face to face with each other and with said side panels so as to be all contained in a compact parallelepiped volume.

[0018] The provision of floor and roof panels that can be folded in two lengthwise makes it possible to maximize the habitable surface area of ​​the prefabricated housing module in its assembled configuration while limiting its size in the transport configuration, so as to enable a large number of them to be transported by sea, land or air in standardized containers.

[0019] According to preferred characteristics of said transportable prefabricated housing module according to the invention: - said side panels are hinged two by two with pivoting via two of their vertical edges so as to form two hinged sub-assemblies of side panels each consisting of a longitudinal side panel and a transverse side panel; - sealing joints are provided at at least some of the interface edges of said half-panels and / or panels between them; - said side panels each comprise a frame covered respectively on its internal and external faces by an internal skin and by a waterproof external skin; - the frame of each side panel comprises a peripheral rectangular frame and several removable uprights extending transversely at regular intervals between the two longitudinal edges of the frame; - each side panel comprises at least one insulating plate extending between the inner and outer skins in the empty space(s) located in the thickness of its frame; - the width of the floor and roof half-panels is approximately equal to the height of the side panels; - the width of the floor and roof half-panels, as well as the height of the side panels is between 2.20 and 2.30 meters; - the length of the floor and roof half-panels, as well as that of the longitudinal side panels, is between 5.90 and 6 meters; - said module comprises several transverse stiffening rods designed to be inserted by threading into and along two half-floor panels so as to ensure rigid support of the floor panel in its horizontal unfolded position; - said module includes screw-on fastening means capable of ensuring the side panels are fixed to the floor panel; - said screw fastening means comprise fixing screws capable of passing through orifices provided at the lower end of the longitudinal side panels and of being screwed into the ends of the transverse stiffening rods; - said screw fastening means comprise fixing screws capable of passing through holes provided at the lower end of the transverse side panels and of being screwed into the floor half-panels; - said module comprises several transverse support beams designed to extend transversely between the interior peaks of the longitudinal side panels so as to ensure rigid support of said roof panel in its horizontal unfolded position; - each support beam has at its ends double-walled fixing brackets intended to be fixed each by screwing onto a corresponding longitudinal side panel and onto the roof panel; - said module comprises four triple-walled corner brackets intended to be positioned at the four upper interior corners of the module, each being fixed by screwing onto a corresponding pair of adjacent side panels, but also onto the roof panel; - said module comprises double-walled brackets designed to be fixed each by screwing onto a corresponding transverse side panel and onto the roof panel; - said module comprises a floor bar designed to be arranged at the level of the longitudinal interior junction zone between the two half-floor panels; and / or - said module includes a ridge designed to be placed at the level of the longitudinal external junction zone between the two half-roof panels.

[0020] The invention also relates, in a second aspect, to an assembly comprising several said housing modules assembled to each other in a modular manner by two of their longitudinal or transverse side panels. Brief description of the drawings

[0031] In the figures, we define an orthogonal reference frame XYZ comprising three axes perpendicular two by two, namely: - an X axis, defining a longitudinal direction, - a Y axis, defining a transverse, horizontal direction, which with the X axis defines a horizontal XY plane, and - a Z axis, defining a vertical direction, perpendicular to the horizontal XY plane.

[0032] [Fig.l] represents a transportable prefabricated housing module according to the invention 1 in its assembled service configuration in which it has a parallelepiped shape.

[0033] In the description which follows and by convention, when reference is made to qualifiers of orientation (such as the terms “vertical”, “transverse” or “horizontal”) or position (such as the terms “upper” or “lower”), the latter will be defined in relation to this assembled service configuration of the prefabricated housing module 1.

[0034] With reference to the exploded view of [Fig.2], this prefabricated housing module 1 includes: - a rectangular floor panel 100 which can be folded in two lengthwise and is designed to extend horizontally on a flat floor or on support members not shown, - a rectangular roof panel 200 also foldable in two lengthwise and designed to extend horizontally above and away from the floor panel 100, - two rectangular longitudinal side panels 300, 400, provided to extend vertically between and along the corresponding longitudinal edges of the floor 100 and roof 200 panels, and - two rectangular transverse side panels 500, 600, intended to extend vertically between and along the corresponding transverse edges of the floor 100 and roof 200 panels.

[0035] The floor panel 100 consists of two rigid rectangular half-panels of the same dimensions 110, 120 pivotally articulated by two of their longitudinal edges, and by means of several hinges 130 spaced longitudinally along these edges (one of them being visible in [Fig.6]).

[0036] As illustrated by [Fig. 3], the half-panels 110, 120 each comprise a metal frame 111, 121 covered on its upper face by an interior floor covering 112, 122.

[0037] The framework 111, 121 of each half-panel 110, 120 comprises a peripheral rectangular frame 111A, 121A, several tubular crosspieces 111B, 121B extending transversely at regular intervals between the two longitudinal edges of the frame 111A, 121A, as well as reinforcing bars 111C, 121C extending obliquely between the two longitudinal edges of the peripheral frame 111A, 121A and between two adjacent transverse elements of this framework (these reinforcing bars being arranged two by two in a V).

[0038] The roof panel 200 is also made up of two rigid rectangular half-panels of the same dimensions 210, 220 pivotally articulated by two of their longitudinal edges, and by means of several hinges 230 spaced longitudinally along these edges (one of them being visible in [Fig.6]).

[0039] As illustrated by [Fig.4], the half-panels 210, 220 each comprise a metal frame 211, 221 covered respectively on its lower and upper faces by an inner skin 212, 222 and by a sealed outer skin 213, 223.

[0040] The frame 211, 221 of each half-panel 210, 220 comprises a peripheral rectangular frame 211A, 221A and several crosspieces 221B extending transversely at regular intervals between the two longitudinal edges of the frame 211A, 221A.

[0041] In order to improve the thermal and acoustic insulation of the roof panel 220, each half-panel 210, 220 also advantageously comprises insulating plates 214, 224 extending between the inner 212, 222 and outer 213, 223 skins in the various empty spaces located in the thickness of the frame 211, 221.

[0042] The two longitudinal side panels 300, 400 and the two transverse side panels 500, 600 have a slightly different conformation from that of the roof half-panels 210, 220.

[0043] As illustrated by [Fig.5] with reference to the transverse side panel 500, each of these side panels 300, 400, 500, 600 comprises a metal frame 510 covered respectively on its internal and external faces by an internal skin 520 and by a waterproof external skin 530.

[0044] The frame 510 of each side panel 300, 400, 500, 600 comprises a peripheral rectangular frame 511 and several uprights 512 extending transversely at regular intervals between the two longitudinal edges of the frame 511.

[0045] For reasons which will be explained below and as is clearly visible in this [Fig. 5], the uprights 512 are advantageously removable and mountable on the frame 511.

[0046] In order to improve the thermal and acoustic insulation, these side panels 300, 400, 500, 600 also advantageously comprise at least one insulating plate 540 extending between the inner 520 and outer 530 skins in the empty space(s) located in the thickness of the frame 510.

[0047] As can be seen in Figures 1, 2 and 5, the housing module advantageously comprises at least one door 550 provided in one of the side panels 300, 400, 500, 600, as well as at least one window 560, 610 provided in one of these side panels.

[0048] These door(s) and window(s) are advantageously arranged in the transverse side panels 500 and 600 in order to allow several modules 1 to be joined together by two of their longitudinal side panels.

[0049] As can be seen in Figures 6 and 8, the upper edge of each side panel 300, 400, 500, 600 has a stepped profile defining on its inner half-portion a respective tenon 370, 470, 570, 670 projecting above the rest of this panel and designed to cooperate by vertical interlocking, during assembly of the module 1, with a groove of complementary shape 230 formed on the inner peripheral periphery of the roof panel 200.

[0050] With reference to figures 2 and 8, the peripheral edge of the floor panel 100 has a stepped profile defining on its lower half-portion a tenon 140 projecting below the rest of this panel and designed to cooperate by lateral interlocking, during assembly of the module 1, with a recess of common shape additional 580 provided on the lower edge of each side panel 300, 400, 500, 600

[0051] In the search for an optimum compromise between rigidity, mass and cost price, the different frames of the half-panels 110, 120, 210, 220 and the side panels 300, 400, 500, 600 are advantageously made of aluminum or an aluminum alloy.

[0052] With a view to achieving an optimum compromise between the quality of thermal and sound insulation, mass and cost price, the various insulating plates 214, 224, 540 of the panels 200, 300, 400, 500 and 600 are advantageously made from a material chosen from mineral wools, polyester wadding, polyurethane foams, extruded polystyrene.

[0053] In order to guarantee excellent resistance to impacts and abrasion, the floor coverings 112, 122 of the floor half-panels 110, 120 as well as the skins 212, 213, 222, 223 of the roof half-panels 210, 220 and those 520, 530 of the side panels 300, 400, 500, 600 are advantageously made of polycarbonate.

[0054] The housing module 1 is also capable of occupying a transport configuration illustrated by [Fig.6] and in which the floor 100 and roof 200 panels are folded vertically while being placed face to face with each other and with the side panels 300, 400, 500, 600, so as to all be contained in a compact parallelepiped volume.

[0055] In order to optimize the habitable surface area of ​​the housing module 1 in its assembled configuration for a given parallelepiped volume in the transport configuration, the width of the floor half-panels 110, 120 and the roof half-panels 210, 220 will advantageously be chosen to be substantially equal to the height of the side panels 300, 400, 500, 600. By “substantially equal” we mean here that the difference between the width of these half-panels 110, 120, 210, 220 and the height of the side panels 300, 400, 500, 600 will be less than or equal to 10%.

[0056] In such a case and as can be seen in this [Fig.6], the parallelepiped volume occupied by this housing module 1 is then barely greater than the sum of the volumes of these half-panels 110, 120, 210, 220 and panels 300, 400, 500, 600 which constitute it, which makes it possible to considerably reduce storage and transport costs.

[0057] Furthermore, and in order to allow the transport of these housing modules 1 inside standardized maritime containers whose internal height dimensions generally vary between 2.35 and 2.40 meters, the width of the floor half-panels 110, 120 and roof half-panels 210, 220 as well as the height of the side panels 300, 400, 500, 600 will advantageously be between 2.20 and 2.30 meters.

[0058] Furthermore, the length of the floor half-panels 110, 120 and roof half-panels 210, 220, as well as that of the longitudinal side panels 300, 400 will advantageously be between 5.90 and 6 meters, so as to allow their transport in 20-foot maritime containers (two rows of these modules 1 can thus be arranged in a row in double 40-foot maritime containers).

[0059] The choice of these dimensions makes it possible to obtain a habitable surface area of ​​the housing module 1 in the assembled service configuration of between 25 and 28 square meters, i.e. approximately double that of current transportable housing modules.

[0060] Such dimensions also make it possible to obtain a length / width ratio whose value between 1.3 and 1.4 is also particularly advantageous in terms of habitability in comparison with that which is much higher than 2 of current transportable housing modules.

[0061] In order to maximize the number of housing modules 1 that can be arranged side by side in the transport configuration across the width of such maritime containers, the thickness of the floor half-panels 110, 120 as well as that of the side panels 300, 400, 500, 600 will advantageously be less than or equal to 55 millimeters. With such a panel thickness, the module 1 has a width of less than 440 millimeters in the transport configuration, which makes it possible to arrange five of them side by side across the width of a maritime container (ten modules 1 can thus be transported in a single 40-foot double container).

[0062] In order to facilitate the assembly operations of the housing module 1, the longitudinal side panels 300, 400 and the transverse side panels 500, 600 are preferably hinged two by two with pivoting via two of their vertical edges and by means of several hinges 430 spaced vertically along these edges (one of them being visible in [Fig.7]).

[0063] In such a case, we thus end up with two articulated sub-assemblies of side panels, namely: - a first subassembly consisting of the longitudinal side panel 300 and the transverse side panel 500; and - a second subassembly consisting of the longitudinal side panel 400 and the transverse side panel 600.

[0064] The prefabricated housing module 1 also includes mounting accessories for ensuring the fixing of the different panels to each other while providing excellent support for the module in its assembled service configuration.

[0065] These mounting accessories comprise several transverse stiffening rods 700, shown in Figures 2 and 3, of length equal to the width of the floor panel 100, and designed to be inserted in a row into and along the crosspieces. tubular 11 IB, 121B of the frame 111, 121 of the half-panels 110, 120 so as to ensure rigid support of this floor panel 100 in its horizontal unfolded position.

[0066] As can be seen in [Fig. 2] and in order to allow the rods 700 to access the crosspieces 11 IB, 121B, orifices 140 are provided in the external longitudinal edges of the peripheral frames 111A, 121A of the frameworks 111, 121 of the half-panels 110, 120 opposite the external ends of these crosspieces 11 IB, 121B.

[0067] Locking means 702 are further advantageously provided to prevent any transverse movement of these rods 700 after their installation. These may for example consist of magnetic pins 702 (one of them being visible in [Fig. 2]) each successively passing through the interior floor covering 112, 122, the top of a crosspiece 111B, 121B, a rod 700 and the bottom of this same crosspiece.

[0068] The mounting accessories also comprise several transverse support beams 710 designed to extend transversely, at regular intervals along the length of the module 1, between the interior peaks of the longitudinal side panels 300, 400, so as to ensure rigid support of the roof panel 200 in its horizontal unfolded position.

[0069] As can be seen in Figures 2 and 7, these beams 710 have at their ends double-walled fixing brackets 711 intended to be fixed each by screwing onto a corresponding longitudinal side panel 300, 400 but also onto the roof panel 200 in order to secure the latter to these longitudinal side panels.

[0070] Other double-walled fixing brackets 720 also visible in FIGS. 2 and 7 are also provided to be each fixed by screwing onto a corresponding transverse side panel 500, 600 but also onto the roof panel 200 in order to secure the latter to these transverse side panels.

[0071] In order to ensure that the longitudinal side panels 300, 400 are held at right angles to the transverse side panels 500, 600 and with reference to FIGS. 2, 7 and 8, the mounting accessories also comprise four triple-walled corner brackets 730 intended to be positioned at the four upper interior corners of the module 1, each being fixed by screwing onto a corresponding pair of adjacent side panels (respectively 300, 500; 400, 500; 400, 600 and 300, 600) but also onto the roof panel 200 in order to increase the number of fixing points of the latter to these longitudinal and transverse side panels.

[0072] The fixing of the transverse side panels 500, 600 to the floor panel 100 is ensured using fixing screws 740 passing through orifices 590 provided in the lower end of these panels and screwed into the peripheral frames 111A, 121A of the frames 111, 121 of the half-panels 110, 120.

[0073] The fixing of the longitudinal side panels 300, 400 to the floor panel 100 is ensured using fixing screws 750 passing through orifices provided at the lower end of these panels and screwing into the ends of the transverse stiffening rods 700.

[0074] In order to guarantee the sealing of the housing module 1 in its assembled configuration, sealing joints are advantageously provided at at least some of the interface edges of the half-panels and / or panels between them.

[0075] Waterproof adhesive strips may also be affixed after assembly along the interface edges of the half-panels and / or panels in order to further improve the level of waterproofing of the housing module 1.

[0076] Advantageously, such interface joints will be provided at the internal longitudinal interface edges of the roof half-panels 210, 220, the vertical interface edges of the transverse side panels 500, 600 with the longitudinal side panels 300, 400, the upper interface edges of the side panels 300, 400, 500, 600 with the roof panel 200, as well as the lower interface edges of these side panels 300, 400, 500, 600 with the floor panel 100.

[0077] As illustrated by figures 2 and 3, the prefabricated housing module 1 may advantageously comprise a floor bar 800 intended to be arranged during assembly (for example using double-sided adhesive) at the level of the longitudinal interior junction zone between the two half-floor panels 110, 120.

[0078] Finally, and with reference to figures 1, 2 and 4, the prefabricated housing module 1 may also include a ridge 900 intended to be arranged during assembly (for example using double-sided adhesive) at the level of the longitudinal external junction zone between the two half-roof panels 210, 220.

[0079] We will now briefly describe the assembly operations of such a prefabricated housing module 1.

[0080] Firstly, the operators in charge of this assembly must horizontally unfold the floor panel 100 so as to rest it, either directly on a flat floor, or in the case of uneven flooring on height-adjustable support stands pre-positioned so as to ensure a perfectly flat reception.

[0081] The stiffening rods 700 must then each be inserted through an orifice 150 and then threaded into and along two aligned tubular crosspieces 111B, 121B, so as to ensure rigid maintenance of this floor panel 100 in its horizontal unfolded position. The locking pins 702 can then be put in place so as to lock these stiffening rods 700 in their position.

[0082] The floor panel 100 can then optionally be lifted by a lifting arm to be positioned on dedicated support means.

[0083] Once the positioning of the floor panel 100 is complete, the first subassembly of side panels 300, 500 is deployed at 90°, then a first triple-walled corner bracket 730 is fixed by screwing onto the two panels forming this subassembly so as to lock it in this deployed position at 90°.

[0084] This first sub-assembly of side panels 300, 500 is then positioned by lateral interlocking on the peripheral edge of the floor panel 100 and fixed by screwing to the latter.

[0085] It is then the turn of the second sub-assembly of side panels 400, 600 to be deployed at 90° before a second triple-walled corner bracket 730 is fixed by screwing onto the two panels forming this sub-assembly so as to lock it in this deployed position at 90°.

[0086] This second sub-assembly of side panels 400, 600 is then positioned by lateral interlocking on the peripheral edge of the floor panel 100 and fixed by screwing to the latter.

[0087] The third and fourth triple-walled corner brackets 730 must then be fixed by screwing, respectively on the side panels 400, 500 and on the side panels 300, 600, so as to rigidly secure the two sub-assemblies of panels 300, 500 and 400, 600.

[0088] Once the positioning of the side panels 300, 400, 500, 600 is complete, the transverse support beams 710 must then be fixed between the inner tops of the longitudinal side panels 300, 400.

[0089] A lifting arm then lifts the roof panel 200 so as to position it vertically resting on these support beams 710. This roof panel 200 can then be deployed horizontally by sliding on these beams 710 and fitted at the level of its peripheral groove 230 on the upper edges of the side panels 300, 400, 500, 600.

[0090] The brackets 71 of the support beams 710 as well as the corner brackets 730 must then be fixed to this roof panel 200.

[0091] The assembly is completed by fixing the double-wall brackets 720 on the transverse side panels 500, 600 and on the roof panel 200, then by the possible installation of the ground bar 800 and the ridge 900.

[0092] These operations of assembling the housing module 1 according to the invention require approximately one hour for a team made up of four operators and having a motorized lifting arm.

[0093] As illustrated by [Fig.9] and in order to enlarge the living area, several living modules 1 can be assembled together in a modular manner by two of their longitudinal or transverse side panels (assembly by the longitudinal panels is however preferred so as to avoid the corridor effect).

[0094] To do this and in order to completely free up their internal space, the side panels to be joined must first be freed from their inner 520 and outer 530 skins, their insulating plates 540 and their uprights 512.

[0095] The peripheral rectangular frames 51 Ides of these two side panels can then be assembled to each other by screwing using several screws 760 passing through their respective uprights as well as several attachment plates 770 which are fixed to their respective lower side members.

[0096] When such a modular configuration is planned from the outset, it is also possible to propose bare side panels consisting solely of the peripheral rectangular frame 511.

[0097] According to embodiment variants not shown, certain elements of the prefabricated housing module according to the invention can be shaped differently. The floor, roof and side panels can thus be made of other materials and have a different structure. This can also be the case for the mounting accessories used.

[0098] Generally speaking, it will be recalled that the present invention is not limited to the embodiments described and shown, but also encompasses all variant embodiments within the reach of those skilled in the art.
