Abstract

The telescopic chassis for mobile homes in flood zones combines several functions to ensure the mobility and safety of housing modules during land submersion. The design of the chassis, the structure of which constitutes the main framework of the module, allows its transport, rapid assembly, elevation during submersion or emergency movement. It is composed of a towable support, equipped with vertical guides for stationing, a central core nested with the support on which the module frame is deployed. During flooding, the module rises vertically around its guides thanks to the inflatable floats located under the floor around the support. Figure to be published for the abstract: [Fig.1]

Description

PITERAC telescopic chassis for mobile homes in flood zones.

• Construction traditionnelle fixe au-dessus de l’eau
• Construction traditionnelle flottante dans une double coque
• Construction légère flottante avec fondations
• Construction légère flottante sans fondations

This innovation applies to certain homes located in flood zones. There are 4 types of construction to deal with flooding:

• Traditional fixed construction above water
• Traditional floating construction in a double hull
• Floating lightweight construction with foundations
• Lightweight floating construction without foundations

In France, the Climate and Resilience Act prohibits fixed constructions in areas exposed to flooding, but mobile homes are accepted. This limits the scope of dwellings authorized in flood zones according to the list above to only light constructions without foundations.

• Assurer la mobilité du lieu de résidence
• Sécuriser l’habitat en zone inondable

We will therefore limit our research to what current technology offers to satisfy the 2 criteria below:

• Ensure mobility of the place of residence
• Securing housing in flood zones

Environmental, societal and regulatory context: Global warming is causing a global rise in sea levels. Intensive urbanization, a source of soil waterproofing, amplifies these effects with the sudden rise in watercourses during rainy episodes. As a result, many homes are located in areas that are submersible or condemned to be in the coming years. The European countries concerned are tightening their legislation to protect property and people, particularly France, where it is forbidden to build or develop new residential areas on land classified as flood-prone. Owners whose land is threatened must move or undertake work to secure existing sites, which only postpones the deadline because the water level is inexorable! Mobile homes are, however, accepted as temporary housing thanks to their mobility, which allows for rapid movement. In the rest of the world, this situation is leading to the displacement of people whose traditional habitat is threatened, which is restricting settlement areas and increasing climate immigration of populations.

• La publication US2023001842 « MOBIL HOME CHASSIS WITH REMOVABLE AXLE AND HITCH ASSEMBLY » : Il s’agit d’un châssis de maison mobile avec essieux et attelage. Le procédé indique la conception d’un cadre rectangulaire amovible équipé d’essieux et d’un attelage en V à fixer sous la structure des mobil home, ceci pour les déplacer et pouvoir être retiré lorsque ceux-ci sont en station. Ce procédé limite donc son champ d’application à rendre escamotable le dispositif de mobilité, afin de mutualiser cet équipement pour plusieurs résidences de même type, avec comme finalité des économies financières. C’est exactement l’inverse de ce qu’il faut faire car de ce fait, le mobil home n’est plus mobile en cas de déplacement d’urgence, car rappelons que la législation exige que celui-ci conserve sa mobilité. Que se passerait-il en cas d’inondation avec plusieurs résidences à déplacer dans un délai court. De plus, les conditions de montage ou démontage en sous-œuvre des essieux et de l’attelage sous le mobile home en station sur ses cales ne sont pas ou mal mentionnées. Quoi qu’il en soit, avec ou sans procédé US2023001842, les mobil home, ne sont pas préservés des inondations, car ils ne pourront pas être déplacés dans un délai court justifié par l’imminence d’un risque de submersion.
• La publication CN214784787 « CAMPING HOUSE ELEVATING SEAT » : Il s’agit d’une plateforme élévatrice pour des maisons de campings. Ce procédé propose un siège à disposer sous l’habitation pour l’élever grâce un dispositif de type compas. Sa fonction principale semble être de pouvoir surélever la maison du sol pour la déplacer ou pour lui éviter de devoir reposer directement sur le sol, ceci dans un but de gain de temps de mise en place lors du montage-démontage et dans un but financier en économisant les fondations pour des constructions temporaires. Pourrait ainsi en découler la fonction de s’élever en cas d’inondation. Cependant, on ne sait pas si ce procédé peut s’adapter à toutes les résidences d’un camping de la caravane au mobil home en passant par le lodge. On ne connait pas non plus les performances du procédé telles que le poids et la hauteur utile à lever, ni si la disposition des poutres rainurées permettant l’élévation est compatible avec la structure des habitations qu’il entend élever. Le procédé CN 214784787, ne semble pas suffisamment mobile pour le remorquage sur route au sens de la réglementation européenne et la fonction élévation lors d’une inondation reste à démontrer. Ce procédé créé pour servir de support à une habitation temporaire ne répond pas au critère de sécurité en cas d’inondation.
• La publication CN216269806 « WATER VILLA FLOATING BODY STRUCTURE » : Il s’agit d’une structure de corps flottants pour une villa aquatique. Ce procédé consiste à disposer dans un cadre, des blocs rigides flottants sous une plaque en acier sur laquelle est édifiée l’habitation. Ce procédé s’adapte à des constructions légères flottantes mais n’offre aucune mobilité car l’habitation posée dessus n’est déplaçable par camion que par grutage en 1 seul bloc ou après démontage des éléments. De plus la présence des seuls corps flottants rigides génère un volume important supérieur en mètre cube à la tonne transportée. Si le procédé CN216269806 répond au critère de sécurité, il ne permet pas la mobilité imposée pour les installations en zones inondables.
• La publication CN112302183A « FOLDING HOUSE SUITABLE FOR RAPID BUILDING IN WATER AREA » : Il s’agit d’une maison pliante préfabriquée adaptée à une construction rapide dans une zone d'eau. Le procédé décrit un corps sous-marin en forme de parapluie flottant grâce à des vessies gonflables supportant une habitation. Cependant le procédé ne décrit pas ou pas clairement les étapes de montage, de mise en station et d’immersion de la maison, ce qui fait que l’on ne voit que l’aspect théorique du procédé mais pas sa fonctionnalité. Le procédé CN112302183A ne semble pas mobile par lui-même et rien n’est dit sur ces performances, ni sur les conditions de transport, de montage ou démontage. Ce procédé ne répond pas au critère de mobilité et celui de la sécurité reste à démontrer.
• La publication WO2022265517 « FLOATING STRUCTURE FOR INSTALLATION IN WATER, A CLOSED RINGSTRUCTURE AND A TUBULAR ELEMENT FOR BUILDING A FLOATING, STRUCTURE, AND A METHOD FOR BUILDING A VERTICAL STRUCTURE » : Il s’agit d’une structure tubulaire superposée destinée à être installée dans l’eau pour accueillir une construction flottante. La fonctionnalité de ce procédé ne semble pas bien définie en l’absence de croquis explicatifs, sauf celui figurant avec l’abrégé. On ne sait pas si la structure est immergée dans l’eau, telle une cage à poisson flottante, ou si elle sert de support immergé dont les parois sont remplies de béton pour fonder une construction située au-dessus. Le procédé WO2022265517 présente donc trop d’incertitude pour en tirer parti ; la mobilité n'étant pas assurée et la sécurité non démontrée.

• La publication CN115158147 « FOLDING PLATE TYPE EXTENSION METHOD FOR MOTOR HOM » : Il s’agit d’une caravane munie de 2 parties extensibles qui se déploie latéralement sur le lieu de stationnement. Le procédé semble bien documenté sur le pliage des plaques lors du montage. S’agissant d’une caravane pouvant être tractée la mobilité semble assurée. Cependant, le procédé CN115158147 est vulnérable à la submersion, comme la plupart des résidences mobiles actuelles, lorsque intervient dans un camping une inondation soudaine comme cela devient plus souvent le cas avec le réchauffement climatique. En conséquence, le procédé CN115158147 ne répond au critère de sécurité.
• La publication n° WO2018178897 « PLATEFORME INSUBMERSIBLE POUR TERRES EXPOSEES AUX ALEAS CLIMATIQUES » Il s’agit d’une habitation flottante ancrée dans un massif béton qui s’élève sur des tubes fixés dans la fondation grâce à un dispositif à crémaillère ou des bouées gonflables lorsque l’eau monte. Cette construction ancrée au sol n’a aucune mobilité et ne sera pas autorisée en zone inondable.

Prior arts: Here are 7 processes representative of the current state of the art:

• Publication US2023001842 "MOBILE HOME CHASSIS WITH REMOVABLE AXLE AND HITCH ASSEMBLY": This is a mobile home chassis with axles and hitch. The method indicates the design of a removable rectangular frame equipped with axles and a V-hitch to be fixed under the structure of the mobile homes, in order to move them and be able to be removed when they are stationed. This method therefore limits its scope of application to making the mobility device retractable, in order to share this equipment for several residences of the same type, with the aim of saving money. This is exactly the opposite of what should be done because as a result, the mobile home is no longer mobile in the event of an emergency move, because remember that the legislation requires that it retain its mobility. What would happen in the event of a flood with several residences to be moved within a short time frame. In addition, the conditions for assembly or disassembly of the axles and the hitch under the mobile home in the station on its chocks are not mentioned or are poorly mentioned. In any case, with or without the US2023001842 process, the mobile homes are not protected from flooding, because they cannot be moved within a short period of time justified by the imminent risk of submersion.
• Publication CN214784787 "CAMPING HOUSE ELEVATING SEAT": This is a lifting platform for camping houses. This process proposes a seat to be placed under the dwelling to raise it using a compass-type device. Its main function seems to be to be able to raise the house off the ground to move it or to avoid it having to rest directly on the ground, this in order to save time during assembly and disassembly and for financial reasons by saving foundations for temporary constructions. This could thus result in the function of raising in the event of flooding. However, it is not known whether this process can be adapted to all residences on a campsite, from caravans to mobile homes and lodges. The performance of the process, such as the weight and useful height to be lifted, is also not known, nor is it possible to determine whether the arrangement of the grooved beams used for lifting is compatible with the structure of the dwellings it is intended to raise. The CN 214784787 process does not appear to be sufficiently mobile for towing on the road in accordance with European regulations and the lifting function during a flood remains to be demonstrated. This process, created to support a temporary dwelling, does not meet the safety criterion in the event of a flood.
• Publication CN216269806 "WATER VILLA FLOATING BODY STRUCTURE": This is a floating body structure for a water villa. This process consists of arranging rigid floating blocks in a frame under a steel plate on which the dwelling is built. This process is suitable for lightweight floating constructions but does not offer any mobility because the dwelling placed on it can only be moved by truck by crane in a single block or after dismantling the elements. In addition, the presence of only rigid floating bodies generates a significant volume greater in cubic meters than the ton transported. If the CN216269806 process meets the safety criterion, it does not allow the mobility required for installations in flood zones.
• Publication CN112302183A "FOLDING HOUSE SUITABLE FOR RAPID BUILDING IN WATER AREA": This is a prefabricated folding house suitable for rapid construction in a water area. The method describes an umbrella-shaped underwater body floating thanks to inflatable bladders supporting a dwelling. However, the method does not describe or does not clearly describe the steps of assembly, setting up and immersion of the house, which means that we only see the theoretical aspect of the method but not its functionality. The CN112302183A method does not seem mobile by itself and nothing is said about its performance, nor about the conditions of transport, assembly or disassembly. This method does not meet the mobility criterion and that of safety remains to be demonstrated.
• Publication WO2022265517 "FLOATING STRUCTURE FOR INSTALLATION IN WATER, A CLOSED RINGSTRUCTURE AND A TUBULAR ELEMENT FOR BUILDING A FLOATING, STRUCTURE, AND A METHOD FOR BUILDING A VERTICAL STRUCTURE": This is a superimposed tubular structure intended to be installed in water to accommodate a floating construction. The functionality of this method does not seem well defined in the absence of explanatory sketches, except for the one appearing with the abstract. It is not known whether the structure is submerged in water, like a floating fish cage, or whether it serves as a submerged support whose walls are filled with concrete to found a construction located above. The method WO2022265517 therefore presents too much uncertainty to take advantage of it; mobility is not ensured and safety has not been demonstrated.

• Publication CN115158147 "FOLDING PLATE TYPE EXTENSION METHOD FOR MOTOR HOM": This is a caravan with 2 extendable parts that unfold laterally on the parking site. The method seems to be well documented on the folding of the plates during assembly. Since it is a caravan that can be towed, mobility seems assured. However, the CN115158147 method is vulnerable to submersion, like most current mobile homes, when a sudden flood occurs in a campsite, as is becoming more common with global warming. Consequently, the CN115158147 method does not meet the safety criterion.
• Publication No. WO2018178897 "UNSINKABLE PLATFORM FOR LANDS EXPOSED TO CLIMATIC HAZARDS" This is a floating dwelling anchored in a concrete block that rises on tubes fixed in the foundation using a rack and pinion device or inflatable buoys when the water rises. This construction anchored to the ground has no mobility and will not be authorized in flood zones.

We can also cite 6 other older publications relating to floating constructions such as:

• “Floating construction” No. WO2007030013 – 2007.03.15
• “The landlocked floating house” no. WO9513212 – 1995.05.18
• “The arrangement of a mobile construction between 2 positions, one resting on the ground and the other floating” no. WO03031732 – 2003.04.17
• “Timber construction in flood zones with flood protection system” No. CZ2012330 – 2012.05.20
• “Survival device in the context of natural disasters consisting of a housing module and its accessories” No. WO2007110489 – 2006.03.03
• "Floating house on land" No. WO9513212 - 1995.05.18

However, all these publications refer to floating constructions that cannot be erected in flood zones because they are not mobile. It can therefore be seen that current techniques, although interesting in certain aspects, do not allow us to satisfy both the mobility and safety criteria. This is why we are presenting the PITERAC telescopic chassis intended for mobile homes located in flood zones.

History of the invention

The “PITERAC telescopic chassis for mobile homes in flood zones” proposed here is an evolution of the “Unsinkable platform for land exposed to climatic risks and hazards” project which was the subject of a patent application No. WO2018178897. This patent application concerned a floating lightweight dwelling fixed on a foundation anchored in the ground, while the current application only concerns the telescopic chassis which ensures the transport, mobility, assembly and buoyancy of the module.

• Le module PITERAC qui désigne la partie habitable de la résidence
• Le châssis PITERAC qui désigne le support et le corps central du module
• PITERAC est le nom générique du concept qui associe le châssis et le module

The PITERAC telescopic chassis is composed of different superimposed parts that constitute the main structure of a housing module intended to be erected in a flood zone. Its design allows the towing and compact packaging of the elements for transport, the positioning of the chassis on its support, the rapid deployment of the module frame on its central core, the elevation by floating of the module by sliding on the chassis guides during a flood. For a good understanding, a glossary is available at the end of the description, but we can distinguish

• The PITERAC module which designates the habitable part of the residence
• The PITERAC chassis which designates the support and the central body of the module
• PITERAC is the generic name of the concept that combines the chassis and the module

• Structure habitable à montage rapide en 1 jour
• Résidence mobile remorquable repliée ou dépliée
• Module muni d’un dispositif d’élévation sans fondations

The invention, the subject of this patent application, relates to the new aspects of the PITERAC chassis, which allows the combination of 3 main functions which did not appear in patent application No. WO2018178897:

• Habitable structure with quick assembly in 1 day
• Towable mobile home folded or unfolded
• Module equipped with a lifting device without foundations

Detailed description of the invention

For referencing and identification of module part numbers in the description, claims or drawings, refer to [Table 1]. The geometric plan of the frame is preferably identical to that of the module of which it serves as a base. It varies in a polygonal base, from a triangle to a dodecagon, up to a circular base. In a preferred embodiment, the frame and its module are characterized by a hexagonal-shaped geometry as shown in all figures from 1 to 10. The hexagonal shape makes it possible to assemble by juxtaposition several modules connected together in a honeycomb.

In this same example of embodiment, the hexagonal geometry shown in all figures from 1 to 10, although not limiting, is the one which seems the most relevant to satisfy both the static and dynamic constraints of structure, as well as the geometric requirements induced by the concept of transport, rapid assembly and elevation of the module.

• Le support du châssis (1) en métal : c’est la partie inférieure du châssis qui comprend l’ensemble roulant (1a) et la base élévatrice (1b). Il a 2 fonctions :
  • (1a) permet le remorquage du châssis, et assure sa mobilité
  • (1b) sert d’interface entre l’ensemble roulant (1a) qui reste au sol et le corps du châssis (2) qui s’élève lors d’une inondation.

• Le corps du châssis (2) en alliage léger : c’est la partie supérieure du châssis située au-dessus du socle (11). Il est composé d’un noyau central, c’est une structure monobloc constituée des pièces (21,22), sur laquelle vient se connecter les fermes triangulées (25,26,27,28,29) supportant l’ossature du plancher (31,32) du module. Le noyau central (21,22) a 3 fonctions :
  • Sert de râtelier de stockage des composants du module (3,4,5) lors du transport
  • Permet le déploiement rapide du module grâce aux éléments d’ossature (25,26,27,28,29,31,32) qui s’articulent autour de lui
  • Autorise l’élévation du module par flottaison lors d’une inondation grâce aux tubes (22) coulissants autour des tubes guides (12)

The PITERAC telescopic chassis is composed of 3 main superimposed parts (1a, 1b, 2) and combined with each other according to :

• The metal chassis support (1): this is the lower part of the chassis that includes the rolling assembly (1a) and the lifting base (1b). It has 2 functions:
  • (1a) allows the chassis to be towed and ensures its mobility
  • (1b) serves as an interface between the rolling assembly (1a) which remains on the ground and the chassis body (2) which rises during a flood.

• The chassis body (2) in light alloy: this is the upper part of the chassis located above the base (11). It is composed of a central core, it is a single-block structure made up of parts (21,22), on which the triangular trusses (25,26,27,28,29) supporting the floor frame (31,32) of the module are connected. The central core (21,22) has 3 functions:
  • Serves as a storage rack for module components (3,4,5) during transport
  • Allows rapid deployment of the module thanks to the framework elements (25,26,27,28,29,31,32) which are articulated around it
  • Allows the module to be raised by flotation during a flood thanks to the tubes (22) sliding around the guide tubes (12)

• L’ensemble roulant (1a), représenté en , , , , est l’assemblage d’un cadre (14), représenté dans une forme préférentielle triangulaire, supporté par un double essieu (17a) muni de roues (17b) et prolongé par un timon télescopique (15a). L’ensemble roulant (1a) assure le remorquage du module replié ou déplié ; il peut être dissocié de la base élévatrice (1b) en actionnant les poignées de (dé)verrouillage (16a) selon la lors d’un transport par container ou par camion, mais aussi lors d’une mise à l’eau du module. Les poignées de (dé)verrouillage (16) sont représentées , dans une forme simplifiée pour leur fonctionnalité. Dans une autre configuration, le cadre (14) sur lequel est fixé l’ensemble roulant (1a) peut avoir une forme polygonale qui épouse la forme du socle (11). L’ensemble roulant (1a) permet ainsi le roulage par remorquage du châssis selon .
• La base élévatrice (1b), représenté en , , , , est un ensemble monobloc composé d’un socle polygonal (11) surmonté par des tubes guides verticaux (12). En partie basse, les tubes (12) sont prolongés par des béquilles télescopiques réglables (13a,13b) pour le calage du châssis lors de la mise en station du module. La forme préférentielle triangulaire du cadre (14) permet de recevoir le socle polygonal (11), de fixer celui-ci sur les montants du cadre (14) grâce aux poignées de verrouillage (16a) tout en permettant l’abaissement des béquilles de calage (13a) situées à chaque angle du socle polygonal (11). Si la forme du cadre (14) épouse celle du support (11), le traitement des angles du cadre (14) devra permettre l’abaissement des béquilles de calage (13a) : voir . Dans une autre configuration plus évoluée, il est possible de remplacer l’ensemble béquille, manchon vissé et broche situé à chaque angle du socle (11) par des vérins hydrauliques ou pneumatiques fixés sous le socle polygonal (11) dans le prolongement du tube (12) et actionnés électriquement depuis le module. En partie haute, les tubes (12) servent de guide pour l’élévation du module. La base élévatrice (1b) permet la mise en station selon la et l’élévation du module selon .
• Le corps du châssis (2), représenté en , , , constitue la structure principale du châssis avec :
  • Le noyau central, représenté en [Fig.6], est composé d’une embase polygonale inférieure (21a) et d’une embase polygonale supérieure (21b) reliées par des tubes creux verticaux (22) coulissants dans les guides (12) fixés sur le socle (11). Les tubes (22), d’une hauteur d’étage, de nombre identique et d’un diamètre légèrement supérieur aux guides (12) solidaires du socle (11), autorisent la libre élévation du module lors d’une inondation et sa redescente lors de la décrue selon la [Fig.7]. Afin de permettre le montage ou le démontage rapide du module, le noyau central (21a,22,21b) est pourvu selon la [Fig.6] de points d’attache des éléments d’ossature du module qui s’articuleront autour de lui.
  • Les fermes triangulées (26,27,28,29), représentées partiellement en [Fig.6], sont assemblées autour du mât (25) fixé au centre de l’embase polygonale supérieure (21b), ceci à partir de la plateforme constituée par les pièces (23,24). Les pièces (26,27,29) renforcées par la pièce (28) constituent ainsi à chaque angle du socle (21b) un triangle inversé permettant de suspendre les façades (4) et le plancher (3) du module. Pour favoriser le montage, l’entrait (29) articulé en tête du tube (22) peut être rabattu verticalement le long du tube (22) lors du transport et déployé horizontalement lors du montage sur l’extrémité de l’arbalétrier (27). De la même façon, la poutre principale du plancher (32) articulée en pied au bas du tube (22) peut être rabattue verticalement le long du tube (22) lors du transport et déployée horizontalement lors du montage en pied du poteau (31). Pour respecter les gabarits du colis transporté ces 2 pièces pourront s’emboiter verticalement dans l’ordre suivant comme indiqué en [Fig.6], l’entrait (29) à l’extérieur, la poutre (32) contre le tube (22).
  • Le corps de châssis (2) est interconnecté à l’ossature du module selon la [Fig.10]

In the proposed embodiment, the polygonal shape chosen is hexagonal according to the , we can distinguish:

• The rolling assembly (1a), shown in , , , , is the assembly of a frame (14), represented in a preferred triangular shape, supported by a double axle (17a) provided with wheels (17b) and extended by a telescopic drawbar (15a). The rolling assembly (1a) ensures the towing of the folded or unfolded module; it can be dissociated from the lifting base (1b) by actuating the (un)locking handles (16a) according to the during transport by container or truck, but also when launching the module into the water. The (un)locking handles (16) are shown , in a simplified form for their functionality. In another configuration, the frame (14) on which the rolling assembly (1a) is fixed may have a polygonal shape which matches the shape of the base (11). The rolling assembly (1a) thus allows the chassis to be rolled by towing according to .
• The lifting base (1b), shown in , , , , is a single-piece assembly composed of a polygonal base (11) surmounted by vertical guide tubes (12). In the lower part, the tubes (12) are extended by adjustable telescopic crutches (13a, 13b) for wedging the chassis when the module is stationed. The preferred triangular shape of the frame (14) makes it possible to receive the polygonal base (11), to fix it on the uprights of the frame (14) using the locking handles (16a) while allowing the lowering of the wedging crutches (13a) located at each corner of the polygonal base (11). If the shape of the frame (14) matches that of the support (11), the treatment of the corners of the frame (14) must allow the lowering of the wedging crutches (13a): see . In another more advanced configuration, it is possible to replace the crutch assembly, screwed sleeve and pin located at each corner of the base (11) by hydraulic or pneumatic cylinders fixed under the polygonal base (11) in the extension of the tube (12) and electrically actuated from the module. In the upper part, the tubes (12) serve as a guide for raising the module. The lifting base (1b) allows the stationing according to the and the elevation of the module according to .
• The body of the chassis (2), shown in , , , constitutes the main structure of the chassis with:
  • The central core, shown in [Fig. 6], is composed of a lower polygonal base (21a) and an upper polygonal base (21b) connected by vertical hollow tubes (22) sliding in the guides (12) fixed to the base (11). The tubes (22), of a floor height, identical in number and with a diameter slightly greater than the guides (12) secured to the base (11), allow the module to be raised freely during a flood and lowered when the water recedes according to [Fig. 7]. In order to allow the module to be quickly assembled or disassembled, the central core (21a, 22, 21b) is provided according to [Fig. 6] with attachment points for the module frame elements which will be articulated around it.
  • The triangular trusses (26,27,28,29), partially shown in [Fig.6], are assembled around the mast (25) fixed to the center of the upper polygonal base (21b), this from the platform constituted by the parts (23,24). The parts (26,27,29) reinforced by the part (28) thus constitute at each corner of the base (21b) an inverted triangle allowing the facades (4) and the floor (3) of the module to be suspended. To facilitate assembly, the tie beam (29) articulated at the head of the tube (22) can be folded vertically along the tube (22) during transport and deployed horizontally during assembly on the end of the rafter (27). In the same way, the main beam of the floor (32) articulated at the foot at the bottom of the tube (22) can be folded vertically along the tube (22) during transport and deployed horizontally during assembly at the foot of the post (31). To respect the dimensions of the package transported, these 2 parts can be fitted vertically in the following order as indicated in [Fig.6], the tie beam (29) on the outside, the beam (32) against the tube (22).
  • The frame body (2) is interconnected to the module frame according to [Fig.10]

Different functions of the PITERAC chassis

1. Le transport : Le module replié dans le châssis peut être tracté ou manutentionné sous forme d’un colis compact selon les , . L’ensemble roulant (1a) selon les , , est composé d’un cadre triangulaire (14) sur lequel sont assemblés 2 essieux (17a) munis de roues (17b) pour équilibrer la charge ainsi qu’un timon rétractable (15a) pour être remorqué. Le socle (11), muni des guides (12), est solidaire du cadre (14) grâce aux poignées de verrouillage (16a) représentées en . Le socle (11) sert d’interface au noyau (21,22), composant la partie centrale du corps du châssis (2), qui constitue le râtelier de stockage des composants du module. Une barre télescopique réglable (18a), fixée par collier (18b) en tête du tube (22) au-dessus du timon (15a) et par une attache (15b) permet de stabiliser la charge lors du roulage. La barre (18a) ne sert que pour les opérations de remorquage du module, qu’il soit replié ou déplié, elle est donc déposée dans les autres cas. On peut distinguer les applications suivantes :
   1. Le transport par remorque selon les [Fig.2], [Fig.3] : en mode remorquage, le châssis repose sur son support (1) surmonté du noyau central (21,22) qui constitue un râtelier de stockage à l’intérieur duquel sont rangés les autres éléments de structure et d’enveloppe du module (3,4,5). Le volume du colis est approximativement de 20m3 pour un poids de 2tonnes environ. L’ensemble, de largeur inférieure à 2.55m, peut être donc tracté sur route par un véhicule léger conduit avec un permis B pour un PTRA (Poids Total Roulant Autorisé) de 3.5tonnes maximum.
   2. Le transport en container selon les [Fig.3], [Fig.4], [Fig.9] : l’ensemble roulant (1a) qui permet le remorquage du châssis peut être séparé facilement du socle (11) pour permettre le transport du module dans un container de 40 pieds « Hight Cube » autorisant un passage de 2.28*2.56mht au droit des portes : il suffit pour cela de déverrouiller les poignées d’assemblage (16a) fixées au socle (11) selon la [Fig.9], ce qui autorise ainsi un colis de dimensions adaptées, formé par le socle et ses guides (11,12) emboités dans le noyau central (21,22), qui contient l’ensemble des pièces d’ossature et d’enveloppe (3,4,5) du module.
   3. La manutention du châssis selon les [Fig.3], [Fig.4], [Fig.9] : l’embase supérieure (21b) du noyau est munie d’oreilles de préhension (19) à chaque angle. Pour les opérations de grutage, il est possible d’élinguer les oreilles (19) pour lever le colis, avec ou sans l’ensemble roulant (1a), ceci en actionnant ou pas les poignées d’assemblage(16b) fixées au socle (11) selon la [Fig.9] qui solidarise l’embase inférieure (21a) avec le socle du châssis (11).

1. Les opérations de montage ou démontage selon les , et s’opèrent en 3 étapes :
   1. La stabilisation du châssis selon la [Fig.5] : le lieu d’installation du module devra comporter une aire relativement plane et un sol ferme. Une fois sur site, le calage du châssis s’effectue par l’abaissement des béquilles télescopiques (13a) situées en bas des tubes (12) à chaque angle du socle (11). Chacune est munie de patin de répartition, percé d’un trou afin de pouvoir être traversé par des piquets (13c) enfichés dans le sol. Dans le prolongement du tube (12), un réglage par manchon à vis et broche (13b) traversant chaque béquille (13a) sert à la mise à niveau du support de châssis (1). Dans une configuration plus évoluée, le calage du châssis peut être facilité en remplaçant l’ensemble (13) avec béquilles, manchons vissés et broches par des vérins hydrauliques ou pneumatiques munis de plaques de répartition en pied. Une fois le support calé, la barre de déplacement (18a) utilisée pour le remorquage peut être déposée. L’ensemble roulant (1a) et l’attache déportée (18b) restent en place, mais il est nécessaire de translater le timon (15a) lors d’un déplacement d’urgence selon 4. Pour des emplacements récurrents dans des terrains de campings par exemple, l’utilisation d’un dallage en béton limité à l’empattement du châssis et muni d’inserts de fixation prépositionnés au droit des béquilles est une bonne solution.
   2. Le châssis est en station, le montage de l’ossature principale peut s’effectuer dans l’ordre suivant selon la [Fig.6] :
      1. Le montage des fermes du toit supportant le plancher représenté à gauche de la [Fig.6] selon le repère B1 :
         1. L’accès et la sécurisation de la plateforme sur l’embase supérieure (21b) qui dispose entre les entretoises d’un platelage caillebotis (23) se fait par des potelets garde-corps enfichables (24a) dans les réservations prévues en partie supérieure des tubes (22) et par 2 chaînettes (24b) en périphérie. L’accès depuis le sol s’effectue par une échelle (24c) crochetée à l’embase supérieure (21b). Les éléments (23,24a-b) sont partiellement représentés en [Fig.6] mais se retrouvent à chaque angle de l’embase (21b).
         2. Depuis la plateforme sécurisée, on peut effectuer la pose du mât (25a) enfiché dans un fourreau au centre de l’embase supérieure (21b) et la mise en place des bracons (26) fixés en pied sur les oreilles de préhension (19) à chaque angle de l’embase jusqu’en haut du mât, par un collier de fixation (25a). Les éléments (19,26) sont partiellement représentés en [Fig.6] mais se retrouvent à chaque angle de l’embase (21b).
         3. Depuis la plateforme sécurisée, on peut effectuer la pose des fermes triangulées à chaque angle de l’embase (21b) avec pour chacune d’elles dans cet ordre précis : le positionnement et l’attache de l’arbalétrier (27) sur le collier de fixation en tête du mât (25b), l’arbalétrier (27) étant soutenu à mi portée par la contrefiche (28) fixée en pied sur l’oreille de grutage (19). Le déploiement horizontal de l’entrait (29) peut ensuite s’effectuer depuis le sol, celui-ci étant replié verticalement pour le transport à l’intérieur de la poutre (32), le long du tube (22). L’entrait (29) vient se connecter à l’extrémité de l’arbalétrier (27), l’ensemble formant ainsi un triangle inversé ayant pour base l’arbalétrier (27) et 2 côtés constitués par le bracon (26) et l’entrait (29). Pour solidariser les fermes entre elles, la pose des sablières de rive (42) fixées en extrémité des entraits (29) s’effectue depuis le sol. Les éléments (19,27,28,29) sont partiellement représentés en [Fig.6] mais se retrouvent à chaque angle de l’embase (21b).
      2. Le montage de la structure principale du plancher représenté à la droite de la [Fig.6] selon le repère B2 :
         1. Le pré-positionnement au sol du ou des flotteurs gonflables (38) en position repliés au pourtour du châssis. Ceux-ci seront fixés sous les poutres (32) et raccordés au dispositif de gonflage (69) avant la pose des panneaux (36) : voir montage de l’enveloppe selon 2.2.3.
         2. La pose de la structure du plancher depuis le sol s’effectue par la fixation à chaque extrémité des arbalétriers (27) d’un poteau suspente (31), sur lequel viendra se connecter la poutre (32) rabattue horizontalement ; celle-ci étant repliée verticalement pour le transport le long du tube (22). Ensuite la pose des profils de rive (33) fixés en extrémité des poutres (32) permet de solidariser les poutres (32) entre elles.
         3. A noter la particularité de mise en place de la poutre (32) située au droit du timon (15a) : en effet, il est nécessaire de faire coulisser le timon au maximum à l’extérieur de telle sorte que celui-ci puisse dépasser suffisamment l’extrémité de la poutre (32) pour pouvoir être attelé lors d’un déplacement d’urgence. Le point de fixation (15b) de la barre de déplacement situé à l’extrémité du timon (15a) coulisse avec lui afin que les oreilles (15b) fixées sur le timon soient accessibles par une trappe ou un insert au travers du plancher depuis l’intérieur du module déplié comme représenté sur la coupe Z.Z en [Fig.8].
         4. La structure du plancher est suspendue à la structure du toit formant ainsi un ensemble contreventé et indéformable aux contraintes extérieures. Le ou les flotteurs seront fixés en anneau lors de l’étape suivante 2) c) sous les poutres (32) du plancher avant la fermeture de celui-ci par la pose des panneaux (36).
   3. Après le déploiement du châssis, le montage de l’enveloppe du module peut d’effectuer selon la [Fig.10] dans l’ordre suivant :
      1. La pose du plancher comprenant les poutres secondaires (34,35) puis les panneaux (36). La fixation du ou des flotteurs (38) sous les poutres (32) et leur raccordement au dispositif de gonflage (69) intervient avant la pose des panneaux (36) selon les [Fig.7], [Fig.8].
      2. Le montage de façades comprenant les poteaux intermédiaires (41), les panneaux (43), les portes (44) et fenêtres (45).
      3. La pose du toit comprenant les poutres secondaires (53,54) supportant la bâche (55).
      4. Le montage de l’enveloppe ne s’inscrit pas directement dans le déploiement du châssis et des éléments qui le composent. Il est mentionné ici pour la compréhension du montage du module. Celui-ci pourra s’effectuer dans cet ordre, de façon manuelle et sécurisée.
      5. Le démontage s’effectue dans un ordre inverse à celui du montage.
2. Le dispositif d’élévation selon la :

For referencing and identification of module part numbers in the description, claims or drawings, refer to [Table 1]. The "PITERAC telescopic chassis for mobile homes in flood zones" provides 5 functions: 1 transportation, 2 assembly-disassembly, 3 elevation, 4 emergency movement, 5 launching:

1. Transport: The module folded into the chassis can be towed or handled in the form of a compact package depending on the , . The rolling assembly (1a) according to the , , is composed of a triangular frame (14) on which are assembled 2 axles (17a) equipped with wheels (17b) to balance the load as well as a retractable drawbar (15a) to be towed. The base (11), equipped with the guides (12), is secured to the frame (14) by means of the locking handles (16a) shown in . The base (11) serves as an interface to the core (21,22), making up the central part of the body of the chassis (2), which constitutes the storage rack for the components of the module. An adjustable telescopic bar (18a), fixed by a collar (18b) at the head of the tube (22) above the drawbar (15a) and by a fastener (15b) makes it possible to stabilize the load when rolling. The bar (18a) is only used for towing operations of the module, whether it is folded or unfolded, it is therefore removed in other cases. The following applications can be distinguished:
   1. Transport by trailer according to [Fig.2], [Fig.3]: in towing mode, the chassis rests on its support (1) surmounted by the central core (21,22) which constitutes a storage rack inside which the other structural and envelope elements of the module are stored (3,4,5). The volume of the package is approximately 20m3 for a weight of approximately 2 tonnes. The assembly, less than 2.55m wide, can therefore be towed on the road by a light vehicle driven with a B license for a GVWR (Authorized Total Rolling Weight) of 3.5 tonnes maximum.
   2. Container transport according to [Fig.3], [Fig.4], [Fig.9]: the rolling assembly (1a) which allows the chassis to be towed can be easily separated from the base (11) to allow the module to be transported in a 40-foot “High Cube” container allowing a passage of 2.28*2.56mht at the doors: all you have to do is unlock the assembly handles (16a) fixed to the base (11) according to [Fig.9], which thus allows a package of suitable dimensions, formed by the base and its guides (11,12) fitted into the central core (21,22), which contains all the frame and casing parts (3,4,5) of the module.
   3. Handling of the chassis according to [Fig.3], [Fig.4], [Fig.9]: the upper base (21b) of the core is equipped with gripping lugs (19) at each corner. For crane operations, it is possible to sling the lugs (19) to lift the package, with or without the rolling assembly (1a), this by actuating or not the assembly handles (16b) fixed to the base (11) according to [Fig.9] which secures the lower base (21a) with the base of the chassis (11).

1. The assembly or disassembly operations according to the , And are carried out in 3 stages:
   1. Stabilization of the chassis according to [Fig.5]: the installation site of the module must have a relatively flat area and firm ground. Once on site, the chassis is stabilized by lowering the telescopic supports (13a) located at the bottom of the tubes (12) at each corner of the base (11). Each is equipped with a distribution pad, pierced with a hole so that it can be crossed by stakes (13c) inserted into the ground. In the extension of the tube (12), an adjustment by screw sleeve and pin (13b) passing through each support (13a) is used to level the chassis support (1). In a more advanced configuration, the chassis can be stabilized by replacing the assembly (13) with supports, screw sleeves and pins by hydraulic or pneumatic cylinders equipped with distribution plates at the foot. Once the support is wedged, the displacement bar (18a) used for towing can be removed. The rolling assembly (1a) and the offset attachment (18b) remain in place, but it is necessary to translate the drawbar (15a) during an emergency move according to 4. For recurring locations in campsites for example, the use of a concrete slab limited to the wheelbase of the chassis and equipped with fixing inserts pre-positioned at the level of the stands is a good solution.
   2. The chassis is in station, the assembly of the main frame can be carried out in the following order according to [Fig.6]:
      1. The assembly of the roof trusses supporting the floor shown on the left of [Fig.6] according to reference B1:
         1. Access and securing of the platform on the upper base (21b) which has a grating deck (23) between the spacers is done by plug-in guardrail posts (24a) in the reservations provided in the upper part of the tubes (22) and by 2 chains (24b) on the periphery. Access from the ground is done by a ladder (24c) hooked to the upper base (21b). The elements (23,24a-b) are partially represented in [Fig.6] but are found at each corner of the base (21b).
         2. From the secure platform, the mast (25a) can be installed, inserted into a sheath in the center of the upper base (21b), and the braces (26) fixed at the foot to the gripping ears (19) at each corner of the base up to the top of the mast, by a fixing collar (25a). The elements (19,26) are partially shown in [Fig.6] but are found at each corner of the base (21b).
         3. From the secure platform, the triangular trusses can be installed at each corner of the base (21b), each of which is carried out in this precise order: positioning and attaching the rafter (27) to the fixing collar at the top of the mast (25b), the rafter (27) being supported at mid-span by the brace (28) fixed at the foot to the crane lug (19). The horizontal deployment of the tie beam (29) can then be carried out from the ground, the latter being folded vertically for transport inside the beam (32), along the tube (22). The tie beam (29) connects to the end of the rafter (27), the assembly thus forming an inverted triangle with the rafter (27) as its base and 2 sides formed by the brace (26) and the tie beam (29). To secure the trusses together, the installation of the edge plates (42) fixed at the end of the tie beams (29) is carried out from the ground. The elements (19,27,28,29) are partially shown in [Fig.6] but are found at each corner of the base (21b).
      2. The assembly of the main structure of the floor shown on the right of [Fig.6] according to reference B2:
         1. Pre-positioning on the ground of the inflatable float(s) (38) in the folded position around the frame. These will be fixed under the beams (32) and connected to the inflation device (69) before installing the panels (36): see assembly of the envelope according to 2.2.3.
         2. The floor structure is laid from the ground by fixing a suspension post (31) to each end of the rafters (27), to which the horizontally folded beam (32) will be connected; the latter being folded vertically for transport along the tube (22). Then the installation of the edge profiles (33) fixed to the end of the beams (32) makes it possible to secure the beams (32) together.
         3. Note the particularity of the installation of the beam (32) located at the right of the drawbar (15a): in fact, it is necessary to slide the drawbar as far as possible outwards so that it can extend far enough beyond the end of the beam (32) to be able to be hitched during an emergency move. The fixing point (15b) of the travel bar located at the end of the drawbar (15a) slides with it so that the ears (15b) fixed on the drawbar are accessible via a hatch or an insert through the floor from the inside of the unfolded module as shown in section ZZ in [Fig.8].
         4. The floor structure is suspended from the roof structure, thus forming a braced assembly that is undeformable under external constraints. The float(s) will be fixed in a ring during the following step 2) c) under the beams (32) of the floor before closing it by installing the panels (36).
   3. After the chassis has been deployed, the module casing can be mounted according to [Fig.10] in the following order:
      1. The installation of the floor comprising the secondary beams (34,35) then the panels (36). The fixing of the float(s) (38) under the beams (32) and their connection to the inflation device (69) takes place before the installation of the panels (36) according to [Fig.7], [Fig.8].
      2. The assembly of facades including intermediate posts (41), panels (43), doors (44) and windows (45).
      3. Installation of the roof including the secondary beams (53,54) supporting the tarpaulin (55).
      4. The assembly of the envelope is not directly part of the deployment of the chassis and its components. It is mentioned here for the understanding of the assembly of the module. This can be done in this order, manually and securely.
      5. Disassembly is carried out in the reverse order to assembly.
2. The lifting device according to the :

1. Le déplacement d’urgence selon la :

At this stage, the module is fully assembled. It rests on its chassis (1,2) in a stationary position, wedged on its supports (13a) and fixed to the ground by stakes (13c). It is necessary to check at this stage that the lifting base which may have been secured to the base (11) during transport is properly unlocked. To do this, simply fold the assembly handle (16b) into the open position (O=open) according to the , to release the telescoping of the tubes (22) around the guides (12). The lifting device, located under the floor around the base (11), is provided by one or more inflatable floats (38), arranged in an open ring on the drawbar (15a). Of circular or elliptical section, the volume of the float(s) must allow the lifting of the loaded module with a safety margin thanks to Archimedes' thrust. Its annular positioning at the median center of the floor allows the correct balance of the loads relative to the center of gravity of the loaded module. During flooding, an automatic triggering device (69b), connected to a pressurized gas cartridge (69a) inflates the float(s) (38). The lifting part of the module structured around the central core (21,22) slides vertically thanks to the tubes (22) around the guides (12) fixed on the base (11) resting on the ground. According to the , when the water level (HW min) is reached, the float inflates and the module rises following the rise of the water up to the level (HW top) which marks the end of the guides (12). Beyond the level (HW top), of the order of a floor height, the module leaves the guides (12) and floats freely like a boat that has been preventively attached by a cable (39) to the base (11) to limit its wandering. An electrically triggered compressed air device can in the same way replace the gas device (69a). In both cases, in the event of a breakdown of the gas device or a power failure, a manual air inflation device (69c) can be operated from inside the module by the occupants. The inflatable float(s) (38) are made of reinforced fabric coated with PVC and polyurethane resin or rubber, a light, flexible and resistant material, which makes it possible to absorb any shocks from objects carried by the water while ensuring good sliding of the water around the float even when loaded with mud or debris. In another configuration not shown in the figures, it is possible to have, instead of the inflatable floats, rigid floats, empty or foamed, of parallelepiped shape, inscribed in the median circle around the chassis. This option has the disadvantage, for equal useful performance, of worsening the weight of the module and the volume of the package transported, as well as increasing the carbon footprint of the assembly.

1. Emergency travel according to the :

1. La mise à l’hivernage ou la relocalisation du module pour la saison touristique estivale.
2. La mise en sécurité préventive du module dans une zone protégée lors d’épisodes climatiques exceptionnels sortant du cadre de la simple inondation par montée des eaux : avis de tsunamis, cyclones, tempêtes dépassant les critères établis au cahier des charges.
3. La mise à l’eau intentionnelle du module décrite en 5.
4. La mise à l’eau du module selon les , , :

At this stage, the module is fully assembled. It rests on its chassis (1,2) in a stationary position wedged on its supports (13a) and fixed to the ground by anchors (13c). It is possible to move the module quickly without having to fold it. During assembly, the drawbar (15a) was telescoped so that the towing hook protrudes sufficiently from the floor to be able to be towed according to mark B2 . The preliminary installation inside the module of the displacement bar (18a), extendable and adjustable, inclined at approximately 45° is necessary to ensure the balance of the loads. The bar (18a) located above the drawbar (15a) is fixed at the foot on the attachment point (15b) integrated into the floor and at the head on the tube (22) by the fixing lug (18b). The loading of the drawbar stand (15c) makes it possible to shift the chassis stabilizing stands (13a) located under the guides (12) of the base (11). To do this, it is necessary to engage under the floor to deactivate the anchors (13c) and telescope the stands (13a) into the high position, this by adjusting for each stand the sleeve assembly screwed onto its pin (13b), according to the . In a more advanced configuration, it is possible to directly operate the hydraulic or pneumatic jacks from inside the module, as indicated in step 2) a) The unfolded module can then be moved, but because of its width, which is greater than that of a road convoy, this is only possible over a short distance and on private land, in particular, for example, in the following situations:

1. Winterizing or relocating the module for the summer tourist season.
2. Preventive securing of the module in a protected area during exceptional climatic episodes beyond the scope of simple flooding by rising water levels: tsunami warnings, cyclones, storms exceeding the criteria established in the specifications.
3. The intentional launching of the module described in 5.
4. Launching the module according to the , , :

It is possible to launch the module if it is used as a temporary floating residence on a body of water: a lake, a pond or a harbor for example. To do this, it is necessary to assemble it as close as possible to the immersion site as indicated in step 2. Once assembled, the module can be moved a short distance as indicated in 4. Once it is at its launch site with a slope of less than 15%, whether it is a boat ramp or a low tide launching site, it is necessary to couple the base (11) to the lower base (21a), then arm the inflatable float (38). The base (11) is locked by folding the assembly handles (16b) into position (L=lock) on the lower base (21a) according to the . To arm the float, simply activate the inflation as indicated in 4. Then, as soon as the lifting part of the module (2,3,4,5) secured to the base (11) floats, the movement bar (18a) can be removed if necessary, the rolling assembly (1a) remains suspended from the module during flotation, which will facilitate its removal from the water. The module thus becomes a floating residence without anchoring. For a prolonged stay in the water or in aggressive water (sea water), it is recommended to remove the rolling assembly before launching because it increases the weight of the module. To do this, simply unlock the assembly handles (16a) in position (O = open) holding the rolling assembly (1a) to the base (11) before activating the floats (38). Thus, when the module floats, it will be freed from its road unit (1a) and thus becomes a floating residence without anchoring, deprived of its rolling device. This will remain at the quay but can be reattached to the base (11) by the reverse maneuver, when leaving the water.
