Abstract
Structure gonflable à double pression membranaire 100 permettant de couvrir et de découvrir facilement tout type d’espace dédié. La spécificité du système réside dans la combinaison de la mise en œuvre de deux volumes (110) d’une part et de l’espace intermembranaire (101, 102) d’autre part. Chaque volume est caractérisé par sa pression propre. Le volume le plus pressurisé est inclus dans le volume secondaire moins pressurisé. Un procédé de liaison mécanique (112) de ces deux volumes à pression indépendante permet de solidariser l’ensemble et d’augmenter à la fois la résistance mécanique et thermique de la couverture (100). La mise en pression indépendante de chaque volume structurel, est assurée séparément par un ventilateur (160, 170) sécurisé, doté de régulation. Ce type de procédé réduit considérablement l’impact carbone de la couverture. La figure du dessin à publier avec l’abrégé est la [Fig 1]. Inflatable structure with double pressure membrane 100 allowing to easily cover and uncover any type of dedicated space. The specificity of the system lies in the combination of the implementation of two volumes (110) on the one hand and the intermembrane space (101, 102) on the other hand. Each volume is characterized by its own pressure. The most pressurized volume is included in the less pressurized secondary volume. A mechanical connection process (112) of these two volumes with independent pressure makes it possible to join the whole together and to increase both the mechanical and thermal resistance of the cover (100). The independent pressurization of each structural volume is ensured separately by a secure fan (160, 170), equipped with regulation. This type of process considerably reduces the carbon impact of the roofing. The figure of the drawing to be published with the abstract is [Fig 1].
Description
La présente invention concerne le procédé de structure gonflable à double pression membranaire permettant de couvrir un espace dédié. La spécificité du système réside dans la combinaison de la mise en œuvre de deux volumes, sous des pressions indépendantes. L’association et la liaison de ces deux volumes, en les intégrant l’un dans l’autre, constitue le principe constructif structurel de l'édifice. Le volume a haute pression est inclus et baigne dans le volume à base pression. L’effet thermodynamique associé à la double pression amplifie la résistance mécanique inter-ossature primaire par rapport à des solutions « simple membrane ».The present invention relates to the method of inflatable structure with double membrane pressure making it possible to cover a dedicated space. The specificity of the system lies in the combination of the implementation of two volumes, under independent pressures. The association and connection of these two volumes, by integrating them into each other, constitutes the structural constructive principle of the building. The high pressure volume is included and bathed in the low pressure volume. The thermodynamic effect associated with double pressure amplifies the primary inter-frame mechanical resistance compared to “single membrane” solutions.
Cette technologie apporte de multiples avantages dans le domaine de la construction qui fait face à de nombreux défis pour limiter son impact carbone lors de l’aménagement de nouveaux espaces clos et couvert. Cette nouvelle technologie y répond par :
- Sa légèreté de conception à réduire considérablement le ratio poids sur surface couverte.
- Sa facilité de mise en œuvre.
- Son isolation thermique.
- Its lightness of design considerably reduces the weight to covered surface ratio.
- Its ease of implementation.
- Its thermal insulation.
Le principe du système réside dans la réalisation d’un premier circuit de pression constitué de boudins, reliés les uns aux autres et servant d’ossature structurelle primaire de l'édifice. La pression à l’intérieur de ces boudins est élevée. Un second circuit de pression est réalisé dans une enveloppe englobant l'ensemble de cette ossature primaire. Cette enveloppe secondaire est réalisée à l’aide d’une membrane dite extérieure et d’une membrane dite intérieure qui sont reliées à l'ossature primaire par un dispositif constructif adéquat. La pression de l'enveloppe secondaire est plus faible. Le procédé se caractérise par la liaison mécanique de ces deux circuits de pression permettant d’augmenter la résistance mécanique et thermique de l’ensemble. L’élément de liaison est du type fermeture à glissière, pour permettre à la fois la perméabilité à l’air et la facilité de mise en œuvre.The principle of the system lies in the creation of a first pressure circuit made up of tubes, connected to each other and serving as the primary structural framework of the building. The pressure inside these tubes is high. A second pressure circuit is produced in an envelope encompassing the entire primary framework. This secondary envelope is made using a so-called exterior membrane and a so-called interior membrane which are connected to the primary framework by an appropriate constructive device. The pressure of the secondary envelope is lower. The process is characterized by the mechanical connection of these two pressure circuits making it possible to increase the mechanical and thermal resistance of the assembly. The connecting element is of the zipper type, to allow both air permeability and ease of implementation.
Un système d'attache spécifique sert d'interface pour ancrer la structure. Cette pièce en matériau souple permet de faire la liaison à la fois entre la zone d’ancrage avec la structure primaire et la structure secondaire. Ce dispositif permet d’homogénéiser la répartition des efforts. Le procédé se caractérise par la mise en œuvre d’un double système d’attache à la zone d’ancrage, en y associant, via une interface, la structure primaire et la structure secondaire. Ce système permet de conserver le caractère indépendant de la structure primaire vis-à-vis de la structure secondaire.A specific fastening system serves as an interface to anchor the structure. This piece of flexible material makes it possible to make the connection between the anchoring zone with the primary structure and the secondary structure. This device makes it possible to homogenize the distribution of efforts. The process is characterized by the implementation of a double system of attachment to the anchoring zone, by associating, via an interface, the primary structure and the secondary structure. This system makes it possible to maintain the independent character of the primary structure with respect to the secondary structure.
Le premier circuit de pression est alimenté par un ventilateur muni d’une régulation lui permettant de compenser la fuite d’air de façon intermittente. L’étanchéité renforcée, conférée à cette ossature primaire, permet de réduire à des fréquences très faibles le taux d'injection d’air comprimé, de maintien en pression. La dépense énergétique est donc très faible.The first pressure circuit is powered by a fan equipped with a regulation allowing it to compensate for the air leak intermittently. The reinforced sealing, given to this primary framework, makes it possible to reduce the rate of compressed air injection and pressure maintenance at very low frequencies. Energy expenditure is therefore very low.
Un second ventilateur basse consommation maintien en pression permanente l'espace entre les 2 membranes dans lequel baignent la structure primaire.A second low-consumption fan maintains permanent pressure in the space between the 2 membranes in which the primary structure is bathed.
La régulation de la pression dans les 2 circuits est automatisée en fonction des conditions climatiques. La pression de l’ossature primaire peut être sécurisée en associant un troisième ventilateur intermittent venant remplacer une défaillance technique du premier. Le procédé se caractérise par la mise en œuvre d’un double système de ventilation indépendant et dédié à chaque volume structurel. Chaque ventilateur est doté de régulation et de système de sécurité. Il est possible de piloter et configurer, en fonction des besoins, les résistances thermiques et mécaniques de la couverture.Pressure regulation in the 2 circuits is automated depending on climatic conditions. The pressure of the primary framework can be secured by combining a third intermittent fan to replace a technical failure of the first. The process is characterized by the implementation of a double independent ventilation system dedicated to each structural volume. Each fan is equipped with regulation and safety system. It is possible to control and configure, according to needs, the thermal and mechanical resistance of the cover.
Le tissu employé pour ce procédé de couverture peut notamment être celui couramment employé pour la réalisation d'architecture textile à savoir un tissu PVC enduit. Le choix de la nature physique du tissu n'est pas limitatif puisqu’il est conditionné à une exigence élevée d'étanchéité à l’air tout en proposant des résistances mécaniques acceptables et un bilan carbone responsable.The fabric used for this covering process can in particular be that commonly used for the production of textile architecture, namely a coated PVC fabric. The choice of the physical nature of the fabric is not restrictive since it is subject to a high requirement for airtightness while offering acceptable mechanical resistance and a responsible carbon footprint.

L’espace intermembranaire entre 101 et 102 peut être ajusté en volume au besoin de la résistance mécanique mais aussi thermique du procédé de couverture. La section des éléments constitutifs de 110 est également variable en fonction de la résistance mécanique et thermique recherchée. Le jeu de réglage des pressions P1 et P2 contribue également à atteindre les valeurs de résistance mécanique et thermique désirées. Un choix judicieux des paramètres est nécessaire.The intermembrane space between 101 and 102 can be adjusted in volume as needed for the mechanical but also thermal resistance of the covering process. The section of the constituent elements of 110 is also variable depending on the mechanical and thermal resistance sought. The pressure adjustment set P1 and P2 also contributes to achieving the desired mechanical and thermal resistance values. A judicious choice of parameters is necessary.
