STRUCTURE SANDWICH ISOLANTE DESTINEE A LA CONSTRUCTION DE BATIMENTS SANDWICH INSULATING STRUCTURE FOR THE CONSTRUCTION OF BUILDINGS
L'invention se rattache au secteur technique de l'isolation thermique dans la conception de constructions de bâtiments ou parties de bâtiments, et aussi en situation de rénovation de bâtiments ou parties de bâtiments. The invention relates to the technical sector of thermal insulation in the design of building constructions or parts of buildings, and also in the situation of renovation of buildings or parts of buildings.
Par le terme général bâtiment , on sous-entend tous types de constructions aux usages les plus divers exigeant une isolation par l'intérieur ou par l'extérieur. By the general term building, one implies all types of constructions with the most diverse uses requiring an insulation by the interior or the outside.
La conception et la réalisation de matériaux isolants dans la fonction thermique est déjà très ancienne, et on connaît par exemple les laines minérales, les polystyrènes qui sont particulièrement utilisés pour leurs propriétés limitant la conductivité thermique. Par ailleurs, les normes en vigueur en France et en Europe à la connaissance du Demandeur mesurent essentiellement, voire exclusivement, la déperdition de chaleur. Les structures isolantes ainsi réalisées peuvent se présenter sous différentes formes à partir de panneaux, de structures sandwich, la matière isolante étant intégrée entre des plaques extérieures et intérieures de protection et de maintien. The design and production of insulating materials in the thermal function is already very old, and we know, for example, mineral wools, polystyrenes which are particularly used for their properties limiting the thermal conductivity. Furthermore, the standards in force in France and in Europe to the knowledge of the Applicant measure essentially, if not exclusively, the heat loss. The insulating structures thus produced can be in different forms from panels, sandwich structures, the insulating material being integrated between outer and inner plates of protection and maintenance.
Si l'on considère exclusivement la question de la seule conductivité thermique, alors les produits actuellement sur le marché répondent aux exigences des normes actuelles. If we consider exclusively the issue of thermal conductivity alone, then the products currently on the market meet the requirements of current standards.
Or, le problème réside dans le fait que d'autres types de déperdition ne sont pas pris en compte par les matériaux isolants ou les structures isolantes actuellement sur le marché. Il s'agit plus particulièrement de déperdition par rayonnement et par convection. However, the problem lies in the fact that other types of loss are not taken into account by the insulating materials or insulating structures currently on the market. It is more particularly radiation and convection loss.
La Directive Européenne liée aux accords de KYOTO pour combattre le réchauffement climatique vient de mettre l'accent sur le contrôle de la consommation énergétique des bâtiments et autres constructions similaires. The European Directive related to the KYOTO agreements to combat global warming has just emphasized the control of the energy consumption of buildings and other similar constructions.
La démarche de Demandeur a donc été d'intégrer les paramètres de déperdition de chaleur à partir d'origines différentes, thermique, et aussi par rayonnement et par conduction pour lesquelles à la connaissance du Demandeur les produits isolants actuellement sur le marché ne sont pas conçus. Applicant's approach was therefore to integrate the parameters of heat loss from different origins, thermal, and also radiation and conduction for which to the knowledge of the Applicant insulating products currently on the market are not designed .
Cette démarche du Demandeur l'a conduit à des recherches nouvelles pour tenter de combiner ces paramètres en vue de la réalisation d'une nouvelle structure d'isolation avec des contraintes très diverses et apparemment incompatibles. This request from the Applicant has led to new research to try to combine these parameters for the realization of a new isolation structure with very diverse and apparently incompatible constraints.
Les produits d'isolation sur le marché et connus sur le marché ont individuellement des capacités isolantes différentes qui influent soit sur la conduction thermique, soit sur la convection thermique, soit sur la convection par rayonnement. Aucun ne répond à ces trois exigences combinées. Insulation products on the market and known on the market individually have different insulating capacities that affect either thermal conduction, thermal convection or radiation convection. None meets all three requirements combined.
Par suite de ses recherches, le Demandeur a ainsi réalisé une structure isolante qui répond à ces trois critères et qui par expérimentation est de nature à répondre au problème posé à l'origine. As a result of his research, the Applicant has achieved an insulating structure that meets these three criteria and that by experimentation is likely to meet the problem originally posed.
La structure isolante selon l'invention permet un contrôle des flux thermiques par conduction, par convection et par rayonnement, par un agencement très particulier des composants et des matériaux constitutifs de ces composants. The insulating structure according to the invention allows a control of the thermal flows by conduction, by convection and by radiation, by a very particular arrangement of components and constituent materials of these components.
Selon une première caractéristique de l'invention, la structure isolante du type sandwich est remarquable en ce qu'elle comprend deux parois apparentes extérieures constituant pour l'une la face extérieure de la structure, et pour l'autre la face intérieure, ces deux parois définissent entre elles par un écartement approprié le volume de la structure, et en ce que entre les deux parois, est intégrée une sous-structure sandwich composée de deux feuilles en matériau aluminium entre lesquelles est disposé un composant intercalaire, et en ce que ladite sous-structure est maintenue en position écartée par rapport aux parois par des ensembles décalés disposés dans la longueur de la structure isolante, en étant parallèles les uns aux autres et espacés, et en ce que à l'intérieur de cette structure sont définies des lames d'air parallèles, et en ce que les lames d'air sont ventilées et se trouvent entre la paroi extérieure de la structure et les feuilles en regard de la sous-structure, et en ce que les lames d'air ne sont pas ventilées et se trouvent définies entre la paroi intérieure et la feuille de la sous-structure. According to a first characteristic of the invention, the insulating structure of the sandwich type is remarkable in that it comprises two outer visible walls constituting for one the outer face of the structure, and for the other the inner face, these two walls define between them by a suitable spacing the volume of the structure, and in that between the two walls, is integrated a sandwich substructure composed of two sheets of aluminum material between which is disposed an intermediate component, and in that said substructure is held in spaced-apart relation to the walls by offset assemblies arranged in the length of the insulating structure, being parallel to each other and spaced apart, and in that inside said structure are defined of air parallel, and in that the air knives are ventilated and are between the outer wall of the structure and the sheets facing the substructure, and in that the air knives are not ventilated and are defined between the inner wall and the sheet of the substructure.
Pour fixer l'objet de l'invention illustrée d'une manière non limitative aux figures des dessins où : - la figure 1 est une vue éclatée avant montage de la structure isolante 25 selon l'invention. - la figure 2 est une vue à caractère schématique selon la figure 1 après montage de la structure isolante selon l'invention en vue perspective partielle pour identifier les composants et leur position respective. - la figure 3 est une vue à caractère schématique d'un ensemble de modules en structure sandwich selon l'invention par une isolation par l'extérieur. For fixing the object of the invention illustrated in a non-limiting manner to the figures of the drawings in which: - Figure 1 is an exploded view before mounting of the insulating structure 25 according to the invention. - Figure 2 is a schematic view according to Figure 1 after mounting the insulating structure according to the invention in partial perspective view to identify the components and their respective position. - Figure 3 is a schematic view of a set of sandwich structure modules according to the invention by an insulation from the outside.
Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins. In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.
La structure isolante est définie dans son ensemble avec différents composants et agencements par (S). Cette structure isolante inclut deux parois apparentes extérieures (1-2) constituant pour l'une la face extérieure (1) de la structure, et pour l'autre la face intérieure (2). Ces deux parois définissent entre elles par un écartement approprié le volume de la structure. Elles sont réalisées avantageusement en polystyrène ou matériau similaire. De par leur faible conductivité, le transfert de chaleur est très limité. The insulating structure is defined as a whole with different components and arrangements by (S). This insulating structure includes two outer walls (1-2) constituting for one the outer face (1) of the structure, and the other the inner face (2). These two walls define between them by a suitable spacing the volume of the structure. They are advantageously made of polystyrene or similar material. Due to their low conductivity, the heat transfer is very limited.
Dans l'espace prévu entre ces deux parois (1-2), est intégrée une sous-structure (Si) sandwich composée de deux feuilles (3-4) en matériau aluminium entre lesquelles est disposé un composant (5) intercalaire. Ce dernier peut être un film à bulles à base de polyéthylène ou une plaque en polystyrène ou matériau similaire. In the space provided between these two walls (1-2) is integrated a substructure (Si) sandwich composed of two sheets (3-4) of aluminum material between which is disposed a component (5) spacer. The latter may be a polyethylene bubble film or a polystyrene plate or similar material.
Cette sous-structure (Si) est maintenue en position écartée par rapport aux parois (1-2) par des ensembles décalés (6-7-8) disposés dans la longueur de la structure isolante, en étant parallèles les uns aux autres et espacés. A l'intérieur de cette structure ainsi définie, on définit des lames d'air parallèles (L1-L2-L3-L4) pour favoriser les mouvements de convection. Les lames d'air (L 1-L2) sont ventilées et se trouvent entre la paroi extérieure (1) de la structure et les feuilles (4) en regard de la sous-structure. Les lames d'air (L3- L4) ne sont pas ventilées et se trouvent définies entre la paroi intérieure (2) et la feuille (3) de la sous-structure (Si). This substructure (Si) is held spaced apart from the walls (1-2) by offset assemblies (6-7-8) arranged in the length of the insulating structure, parallel to one another and spaced apart. . Within this structure thus defined, parallel air blades (L1-L2-L3-L4) are defined to promote convection movements. The air knives (L 1 -L 2) are ventilated and are located between the outer wall (1) of the structure and the sheets (4) facing the substructure. The air knives (L3-L4) are not ventilated and are defined between the inner wall (2) and the sheet (3) of the substructure (Si).
Selon une disposition de l'invention, la sous-structure (Si) avec les ensembles décalés (6-7-8) est décalée par rapport aux panneaux (1-2) en débordement extérieur d'un côté latéral, en rentrant intérieur de l'autre côté latéral de la structure, et ceci pour permettre un emboîtement des modules de structure isolante (6), évitant ainsi les ponts thermiques. According to an arrangement of the invention, the substructure (Si) with the shifted sets (6-7-8) is shifted with respect to the panels (1-2) outwardly overflowing on a lateral side, the other lateral side of the structure, and this to allow interlocking insulating structure modules (6), thus avoiding thermal bridges.
La liaison des différents composants s'effectue par collage ou autrement. The connection of the different components is done by gluing or otherwise.
La structure isolante selon l'invention prévoit ainsi deux séries de lames d'air (L1-L2) ventilées, côté face extérieure afin d'évacuer la chaleur d'été, l'autre sera de lame d'air (L3-L4) non ventilée, côté face intérieure pour préserver la chaleur en hiver ou la fraîcheur en été à l'intérieur du bâtiment ou de la construction ainsi équipée. The insulating structure according to the invention thus provides two sets of ventilated air knives (L1-L2), on the outer side to evacuate the summer heat, the other will be air (L3-L4) unventilated, interior side to preserve heat in winter or cool in summer inside the building or construction thus equipped.
En terme de fonctionnement selon les périodes été / hiver, les résultats sont les suivants : In terms of operation according to the summer / winter periods, the results are as follows:
- A partir de la face externe du panneau (1) de la structure isolante (S) : la face extérieure du panneau (1) absorbe la chaleur sans la transférer ou de manière très limitée. Le rayonnement solaire par infrarouge traverse le panneau (1) mais va buter contre la feuille (1) en aluminium de la sous-structure (S 1). L'aluminium étant réflecteur, il va renvoyer ce rayonnement à travers le panneau (1). Les lames d'air (L1-L2) entre les panneaux (1) et la feuille (3) en aluminium seront ventilées lors de la mise en place et permettront d'évacuer la chaleur renvoyée par la feuille (3) en aluminium et faciliter les mouvements de convection. Les cales d'appui (6-7-8) réalisées en matériau polystyrène ne transmettront que très faiblement la chaleur. Ainsi, c'est la feuille (3) qui permettra la conduction et l'évacuation de cette chaleur pour la ventilation. - From the outer face of the panel (1) of the insulating structure (S): the outer face of the panel (1) absorbs heat without transferring it or in a very limited manner. Infrared solar radiation passes through the panel (1) but will abut against the aluminum sheet (1) of the substructure (S 1). Aluminum being reflective, it will send back this radiation through the panel (1). The air gaps (L1-L2) between the panels (1) and the sheet (3) made of aluminum will be ventilated during the installation and will evacuate the heat returned by the sheet (3) aluminum and facilitate convection movements. Support shims (6-7-8) made of polystyrene material will transmit heat only very slightly. Thus, it is the sheet (3) that will allow the conduction and evacuation of this heat for ventilation.
A partir de la face interne des panneaux (2), celle-ci absorbe la chaleur ou fraîcheur que très faiblement, n'étant pas conducteur. Le rayonnement par infrarouge traversera le panneau (2) pour venir en butée contre la feuille (4) en regard en aluminium. La feuille aluminium ayant des propriétés de réflexion, va renvoyer le rayonnement émis à travers le panneau (2). Les lames d'air (L3-L4) entre le panneau (2) et la feuille (4) seront non ventilées lors de la mise en place et permettront de maintenir la chaleur et /ou fraîcheur selon la situation. From the inner face of the panels (2), it absorbs heat or coolness very weakly, not being conductive. The infrared radiation will pass through the panel (2) to abut against the sheet (4) facing aluminum. The aluminum sheet having reflective properties, will return the radiation emitted through the panel (2). The air gaps (L3-L4) between the panel (2) and the sheet (4) will be unventilated during installation and will maintain heat and / or freshness depending on the situation.
La structure isolante selon l'invention répond parfaitement par la combinaison et l'agencement de ses composants et matériaux constitutifs au problème posé à l'origine en contrôlant les différentes déperditions thermiques par convection, par rayonnement et par déperdition. Cette structure isolante est apte pour l'isolation par l'extérieur des bâtiments, l'isolation des caves ou vides sanitaires, et aussi pour l'isolation par l'intérieur. The insulating structure according to the invention responds perfectly by the combination and arrangement of its constitutive components and materials to the original problem by controlling the various heat losses by convection, radiation and loss. This insulating structure is suitable for insulation from the outside of buildings, the insulation of cellars or crawl spaces, and also for insulation from the inside.
25 On a représenté à titre d'exemple illustratif la mise en oeuvre de l'invention en situation d'isolation par l'extérieur.20 La façade à recouvrir inclut une fenêtre (10) avec une pluralité de modules de structure isolante (S) imbriqués latéralement et en appui étagé. Pour assurer une continuité des flux, il faut bien sûr que les différentes lames d'air (L1-L2-L3-L4) soient en alignement, et on a représenté par (F1) les flux d'air. L'empilement décalé des panneaux assure une continuité de flux des différentes lames d'air (L1-L2-L3-L4). Des grilles de ventilation (11) sont disposées sur les modules. Une liaison (12) par tuyau perforé est établie entre les grilles selon les besoins. As an illustrative example, the use of the invention in an external isolation situation is represented. The facade to be covered includes a window (10) with a plurality of insulating structure modules (S). nested laterally and in stepped support. To ensure flow continuity, it is of course necessary that the different air gaps (L1-L2-L3-L4) are in alignment, and is represented by (F1) the air flows. The offset stacking of the panels ensures continuity of flow of the different air gaps (L1-L2-L3-L4). Ventilation grilles (11) are arranged on the modules. A perforated pipe connection (12) is established between the grids as required.
Les caractéristiques dimensionnelles des modules et des composants des structures isolantes sont définies selon les besoins. The dimensional characteristics of the modules and components of the insulating structures are defined as required.
