Description
Le procédé décrit s'applique à la réalisation d'isolation par l'extérieur des ouvrages destinés généralement à l'habitation, aux bureaux & bâtiments industriels qui doivent être maintenus à une température approximativement constante. Dans le contexte environnemental des Nouvelles Réglementations Thermiques 2020 qui imposent la réalisation de bâtiments « passifs », et le coût de l'énergie dans le futur, il est fondamental que les bâtiments qui sont exploités avec la contrainte d'une température pratiquement constante soient d'une part parfaitement isolés et d'autre part bénéficient d'une inertie thermique élevée.The method described applies to the realization of insulation from the outside of works generally for housing, offices & industrial buildings that must be maintained at an approximately constant temperature. In the environmental context of the New Thermal Regulations 2020 which impose the construction of "passive" buildings, and the cost of energy in the future, it is essential that buildings that are operated with the constraint of a practically constant temperature are d on the one hand perfectly isolated and on the other hand enjoy a high thermal inertia.
Pour réaliser une isolation de forte résistance thermique sous une épaisseur minimum, il n'existe pas d'autre solution que de rapporter sur la structure un isolant dont l'épaisseur sera fonction du λ (conductivité thermique en W/m.°C) de l'isolant choisi et de la résistance thermique visée pour l'ouvrage. L'isolation peut être disposée soit à l'intérieur du logement soit à l'extérieur et parfois sur les 2 faces (intérieure & extérieure). A contrario de la solution de l'isolation extérieure, l'isolation posée à l'intérieur prive le bâtiment de son inertie thermique, présente des difficultés pour annihiler les effets néfastes des ponts thermiques au niveau des jonctions planchers & refends avec les murs extérieurs, et conduit à une emprise importante sur le volume habitable. Concernant ce dernier inconvénient, il est important de remarquer économiquement que :
- le prix de la construction est sensiblement proportionnel à la surface projetée sur un plan horizontal du bâtiment à construire (SHON).
- Le prix de vente est proportionnel à la surface habitable (ou surface balayable).
- La marge se caractérise par la différence entre ces 2 prix.
- the price of construction is substantially proportional to the projected area on a horizontal plane of the building to be constructed (SHON).
- The selling price is proportional to the living area (or sweeping area).
- The margin is characterized by the difference between these two prices.
Dans le cas d'une isolation rapportée à l'intérieur des logements la surface balayable est égale à la SHON déduction faite du périmètre que multiplie l'épaisseur des parois structurelles extérieures à laquelle il convient de rajouter l'épaisseur de l'isolant.In the case of an insulation reported inside the housing the sweeping surface is equal to the SHON deduction made of the perimeter that multiplies the thickness of the external structural walls to which it is necessary to add the thickness of the insulation.
L'homme de l'art comprend ainsi aisément qu'à épaisseur d'isolant égale, la solution de l'isolation posée à l'extérieur conduit soit à une augmentation de la marge, soit à marge égale à une réduction du prix.The person skilled in the art thus easily understands that with an equal thickness of insulation, the solution of the insulation placed on the outside leads either to an increase in the margin or to a margin equal to a reduction in the price.
Pour réaliser une isolation thermique extérieure qui satisfasse aux NRT 2020, il est nécessaire de procéder à la pose sur la structure d'une isolation thermique de 20 à 30 cm au minimum. Ce complexe isolant doit être généralement recouvert par un parement de finition (enduit d'épaisseur variable, pierre ou bois). Le poids de ce parement (entre 75 et 125 kg/m2) doit être transmis à la structure porteuse. On comprend très facilement que plus l'épaisseur de l'isolant est importante, plus le moment est élevé, et donc plus cette liaison est difficile à réaliser. Pour des isolations inférieures à 10cm il est traditionnellement possible de fixer directement l'isolant sur la structure au moyen de clous chevillés qui possèdent un dispositif de rupture de ponts. Par contre pour des isolations supérieures à cette valeur de 10 cm, la valeur du moment, et donc des forces à reprendre, est élevée ce qui conduit à des mises en oeuvre onéreuses et peu durable en raison des risques accrus de fluage des fixations sous forces élevées.To achieve an external thermal insulation that meets the NRT 2020, it is necessary to install on the structure a thermal insulation of 20 to 30 cm minimum. This insulating complex must generally be covered by a finishing layer (varnish thickness, stone or wood). The weight of this facing (between 75 and 125 kg / m 2 ) must be transmitted to the supporting structure. It is very easily understood that the greater the thickness of the insulation, the higher the moment, and therefore this connection is difficult to achieve. For insulations smaller than 10 cm it is traditionally possible to directly fix the insulation on the structure by means of pegged nails which have a bridge breaking device. On the other hand, for insulations greater than this value of 10 cm, the value of the moment, and therefore of the forces to be resumed, is high, which leads to expensive and unsustainable implementations because of the increased risks of creep of the fastenings under forces. high.
Traditionnellement, pour répondre à ces impératifs, les entreprises exécutent cette fonction après la construction des voiles extérieurs. Suivant ce procédé, les ouvriers procèdent sur le chantier à la pose d'équerres (5/m2) chevillées (4 chevilles/équerre) sur les voiles extérieurs. La dimension des ailes de ces pièces de fixation est largement supérieure à l'épaisseur de l'isolant. Les dites équerres perforent l'isolant qui est lui-même verrouillé par un dispositif, en bois ou métallique, lui-même fixé sur les équerres. Le parement (bardage, enduit ou pierre) est ensuite rapporté sur ces verrous.Traditionally, to meet these requirements, companies perform this function after the construction of the outer sails. Following this procedure, the workers proceed on site to the laying of brackets (5 / m 2 ) pegged (4 pegs / square) on the outer sails. The dimension of the wings of these fasteners is much greater than the thickness of the insulation. The said brackets perforate the insulation which is itself locked by a device, wood or metal, itself fixed on the brackets. The siding (cladding, plaster or stone) is then attached to these locks.
Ces technologies traditionnelles réalisées en hauteur sur chantiers sont longues & onéreuses. Par ailleurs, les fixations rapportées ne sont pas durables car soumises au phénomène de fluage qui conduit dans le temps à des désordres dus au décrochage des parements. Des dispositifs traditionnels destinés à former un volume isolant sont connus de
Enfin, il faut signaler un autre inconvénient lié à la durée de vie (30 ans en moyenne) des isolants traditionnellement utilisés. Qu'ils soient posés en extérieur, et à fortiori en intérieur, leur remplacement conduit à des travaux affectant non seulement l'isolation mais également le parement décoratif. Ces travaux représentent un coût important et une gêne pour les occupants.Finally, there is another drawback related to the lifetime (30 years on average) of insulation traditionally used. Whether installed outdoors, and especially indoors, their replacement leads to work affecting not only the insulation but also the decorative siding. These works represent a significant cost and inconvenience for the occupants.
Le dispositif ci-dessous revendiqué permet de pallier particulièrement les inconvénients suivants :
- Pas de mise en oeuvre sur le chantier grâce à un système de préfabrication dont le transport est assuré replié afin de limiter au maximum le volume des vides transportés,
- Inertie thermique interne à l'enveloppe habitable,
- Assurer la possibilité de remplacement des isolants sans destruction des parements.
- No implementation on site thanks to a prefabrication system whose transport is ensured folded in order to limit as much as possible the volume of the transported voids,
- Thermal inertia internal to the habitable envelope,
- Ensure the possibility of replacement of insulation without destruction of siding.

Afin de permettre le repliement de l'ensemble, un certain nombre de relations sont impératives :
- les distances entre les axes 2a-2b des pièces 2 & les axes 4a- 4b des pièces 4 sont identiques ;
- Cette distance est par ailleurs égale à la moitié de la distance entre les axes 3a-3b;
- La distance entre les axes 5a-5b est au moins inférieure à la somme des distances des axes 3a-3b augmentée de la longueur « L1 » (
distance de 3a à 4a) de la pièce {1} ; - Préférentiellement, afin que l'effet tridimensionnel soit optimum, les suspentes 2, 4 & 3 dépliées présenteront un angle aussi proche que possible de 45° avec le plan horizontal. Cette condition complémentaire souhaitable fixe la distance optimale des axes 5a-5b.
- the distances between the
axes 2a-2b of theparts 2 & theaxes 4a-4b of theparts 4 are identical; - This distance is also equal to half the distance between the
axes 3a-3b; - The distance between the
axes 5a-5b is at least less than the sum of the distances of theaxes 3a-3b increased by the length "L1" (distance 3a to 4a) of the workpiece {1}; - Preferably, so that the three-dimensional effect is optimum, the
2, 4 & 3 unfolded will have an angle as close as possible to 45 ° with the horizontal plane. This desirable additional condition sets the optimum distance from thelines axes 5a-5b.
Cette disposition repliable présente 2 avantages principaux :
- Bien que pouvant dégager un volume de grande épaisseur destiné à recevoir un isolant non lié voire pulvérulent, le volume stocké et transporté est minimum ;
- En position dépliée, la structure constituée par les suspentes {3} & {4} d'une part et {2} d'autre part, situé dans des plans sécants et préférentiellement inclinés approximativement à 45° par rapport à l'horizontal, réalise une structure tridimensionnelle.
- Although able to release a large volume intended to receive an unbound insulation or powder, the volume stored and transported is minimum;
- In unfolded position, the structure constituted by the lines {3} & {4} on the one hand and {2} on the other hand, located in secant planes and preferably inclined approximately at 45 ° with respect to the horizontal, realizes a three-dimensional structure.

Le bloc de serrage extérieur 8a comprend un pied préférentiellement cylindrique sur lequel est disposé un trou d'axe 8g disposé parallèlement aux axes la &1b. le dit bloc de serrage extérieur 8a comporte également un logement 8f destiné à recevoir un joint d'étanchéité 8h. Afin de répondre aux règlements incendie, le bloc de serrage extérieur 8a est préférentiellement armé par un crochet de sécurité 8c en matière résistant au feu (par exemple acier) ;
- ∘ Une entretoise
lame d'air 8b coaxiale avec l'axe principal du bloc de serrage extérieur 8a.Cette pièce 8b est préférentiellement en matière qui présente une résistance thermique élevée (PVC ou autre par exemple). Enfin sur la face d'appui extérieure la pièce 8b comporte des rainures destinées à renforcer l'étanchéité au niveau de l'appui sur lefilm d'étanchéité 10. La hauteur de l'entretoise 8b sera choisie de façon à maintenir une distance entre le film d'étanchéité de l'isolant 19 et le film d'étanchéité 10 extérieur de valeur au moins égale à l'épaisseur de la lame d'air réglementaire 14 (engénéral 2 cm) ; - ∘ Un crochet de sécurité 8c incorporé à la fabrication, en général injecté.
Le dit crochet 8c entoure les axes des alésages la & 1b. Cette disposition permet d'assurer une fixation de sécurité du parement extérieur en cas de destruction des parties sensibles au feu par exemple de la pièce {8} et sécurise l'intervention du personnel d'incendie ; - ∘ Bien que facultatif mais préférable, un
joint d'étanchéité 8d extérieur à la lame d'air. Ce joint est serré entre la pièce {8} et lefilm d'étanchéité extérieur 10. Le rôle du dit joint 8d est d'éviter toute pénétration d'eau à l'intérieur de la lame d'air ; - ∘ Un organe de serrage 8e. La fonction de serrage de cet organe 8e peut par exemple être réalisée comme représenté par un excentrique dont l'axe de rotation est coïncident avec l'axe 8g. Cet axe d'excentrique sera en matière qui présente une résistance au feu élevée. Ainsi, en cas d'incendie, le parement sera relié à la structure par des éléments présentant une résistance au feu qui laissera aux services de sécurité le temps d'intervention sans risque de chute du parement ;
- ∘ Une paroi coffrante d'isolant 9. La dite paroi 9 est destinée à confiner l'isolant à l'intérieur du
volume isolant 16. La paroi 9 est filtrante et autorise sans dégradation le passage des condensats duvolume isolant 16 dans lalame d'air 14. - ∘ Un
film extérieur d'étanchéité 10. Les rôles du dit film sont :- ▪ d'interdire, ou pour le moins de limiter la pénétration des eaux de ruissellement sur le parement extérieur
- ▪ Servir de support de projection en cas de parement extérieur projeté.
∘ Une grille 11 qui constituera une armature (en acier galvanisé ou composite) pour les parements extérieurs projetés.
- La
figure 3b représente un exemple de réalisation de l'excentrique 8e. Le dit excentrique a son axe de rotation coïncident avec l'alésage 8g de la pièce de serrage 8a - Sur la
figure 3c est schématisé un sous-ensemble {2} qui constitue la suspente à rupture de joint. Le dit sous-ensemble se compose de :∘ Une pièce 2c suspente de rupture thermique. La dite pièce 2c en matière (composite) présente une résistance thermique élevée. Sa section sera suffisante afin de supporter les contraintes de traction engendrées par le poids du parement extérieur (par exemple 150kg/m2).La pièce 2c comporte deux alésages dont les axes 2a & 2b sont parallèles.L'alésage d'axe 2b est destiné à recevoir un verrou intérieur 7 lié au mur (neuf ou ancien) 6 à isoler.L'alésage d'axe 2a est destiné à recevoir une bague 13, décrite ci après. Avantageusement, la pièce {2} possède un clips 2d qui confirme le verrouillage des pièces {4} & {2} lorsque leurs axes principaux sont confondus (c'est-à-dire en position totalement ouverte)- ∘ Une bague à
rupture 13 en matériau élastique (caoutchouc par exemple). La dite bague 13 est préférentiellement cylindrique et de diamètre sensiblement égal à celui de l'alésage d'axe 2a de la pièce 2c. Elle est munie d'untrou 13acoaxial avec l'axe 2a.Ce trou 13a est destiné à recevoir la forme droite 4c de la suspente tridimensionnelle articulée {4}.Une fente 13b qui relie le trou intérieur au cylindre extérieur, permet le passage de la tige droite 4c de la suspente articulée {4}.Ce dispositif 13 constitue un amortisseur qui découple les masses du parement extérieur et la Masse de la structure. Cette technologie particulière qui respecte la loi « masse-ressort-MASSE » répond aux conditions d'affaiblissement acoustique.
- Sur la
figure 3d est schématisée la suspente articulée 4. La dite pièce est constituée par un fil dont le profil a une forme en Vé et une section préférentiellement circulaire. Les parties droites 4c & 4c' ont des axes 4a & 4b sensiblement parallèles. Les parties droites 4c & 4c' sont situées dans un même plan mais leurs médiatrices ne sont pas coïncidentes. Par ailleurs la distance normale entre les axes 4c-4c' est sensiblement égale à celle entre les axes 2a-2b de la pièce {2} - La
figure 3e est une vue de détail qui représente le profil de la pièce 4 dont le pas est identique à celui de la pièce 3 mais de hauteur différente - Sur la
figure 3f est schématisée la suspente tridimensionnelle decompression 3. La dite suspente a un profil et une section de même nature que ceux décrits pour la suspente articulée 4. Toutefois, pour des raisons de résistance mécanique, les dimensions de la section peuvent être différentes. De même, pour respecter le principe dont il est fait mention dans la description attachée à lafigure 1 , la distance entre les axes 3a-3b est double de celle entre les axes 4a-4b - La
figure 3g est l'assemblage schématique des pièces {2}, {3} & {4}. Le dit assemblage réalise le principe décrit en planche du dispositif articulé revendiqué.
- On the
figure 3a the outer block subset {1} is schematized. The said subset consists of:- ∘ An
outer clamping block 8a of insulating material (for example polyurethane) provided with two parallel axis bores la 1b which are respectively coincident with theaxes 3a & 4a. Theouter clamping block 8a comprises a preferably cylindrical foot on which is disposed a hole ofaxis 8g disposed parallel to theaxes 1a and 1b. saidouter clamping block 8a also has ahousing 8f for receiving a seal 8h. In order to meet the fire regulations, theouter clamping block 8a is preferably reinforced by asafety hook 8c of fire-resistant material (for example steel); - ∘ An
air knife spacer 8b coaxial with the main axis of theouter clamping block 8a. Thispart 8b is preferably made of a material that has a high thermal resistance (PVC or other example). Finally, on the outer support face, thepart 8b has grooves intended to reinforce the seal at the level of the support on the sealingfilm 10. The height of thespacer 8b will be chosen so as to maintain a distance between the sealing film of the insulator 19 and the outer sealing film of value at least equal to the thickness of the regulatory air gap 14 (generally 2 cm); - ∘ A
safety hook 8c incorporated in the manufacture, usually injected. Saidhook 8c surrounds the axes of the bores la 1b. This provision makes it possible to ensure a security fastening of the outer facing in the event of destruction of the parts sensitive to fire by example of part {8} and secures the intervention of the fire personnel; - ∘ Although optional but preferable, a
gasket 8d outside the air gap. This seal is clamped between the part {8} and theouter sealing film 10. The role of saidseal 8d is to prevent any water penetration inside the air gap; - ∘ A clamping
member 8e. The clamping function of thismember 8e can for example be carried out as represented by an eccentric whose axis of rotation is coincident with theaxis 8g. This eccentric axis will be made of a material that has a high fire resistance. Thus, in case of fire, the facing will be connected to the structure by elements with a fire resistance that will leave the security services the intervention time without risk of falling of the facing; - ∘ A shuttering wall of insulation 9. The said wall 9 is intended to confine the insulation inside the insulating
volume 16. The wall 9 is filtering and allows without degradation the passage of the condensates of the insulatingvolume 16 in the blade.air 14. - ∘ An
outer sealing film 10. The roles of the said film are:- ▪ to prohibit, or at least limit, the penetration of runoff water on the exterior facing
- ▪ Serve as a projection support for projected exterior siding.
- ∘ A
grid 11 which will constitute a reinforcement (made of galvanized steel or composite) for projected exterior siding.
- ∘ An
- The
figure 3b represents an exemplary embodiment of the eccentric 8e. The said eccentric has its axis of rotation coincide with thebore 8g of theclamping piece 8a - On the
figure 3c is schematized a subset {2} which constitutes the line with joint failure. The said subset consists of:- ∘ A 2c piece with thermal break. The said
piece 2c of (composite) material has a high thermal resistance. Its section will be sufficient to withstand the tensile stresses caused by the weight of the outer facing (for example 150kg / m 2 ). Thepart 2c has two bores whoseaxes 2a & 2b are parallel. Theaxis bore 2b is intended to receive aninner lock 7 connected to the wall (new or old) 6 to isolate. Theaxis bore 2a is intended to receive aring 13, described below. Advantageously, the part {2} has aclip 2d which confirms the locking of the pieces {4} & {2} when their main axes are merged (that is to say in the fully open position) - ∘ A
rupture ring 13 made of elastic material (rubber for example). Saidring 13 is preferably cylindrical and of diameter substantially equal to that of the axis bore 2a of thepart 2c. It is provided with ahole 13a coaxial with theaxis 2a. Thishole 13a is intended to receive thestraight form 4c of the articulated three-dimensional suspension {4}. Aslot 13b which connects the inner hole to the outer cylinder, allows the passage of theright rod 4c of the articulated hanger {4}. Thisdevice 13 constitutes a damper which decouples the masses of the outer face and the mass of the structure. This particular technology which respects the law "mass-spring-MASS" answers the conditions of weakening sound.
- ∘ A 2c piece with thermal break. The said
- On the
figure 3d is schematically articulatedhanger 4. The said piece is constituted by a wire whose profile has a shape Vee and a preferably circular section. Thestraight portions 4c & 4c 'haveaxes 4a & 4b substantially parallel. Thestraight parts 4c & 4c 'are located in the same plane but their mediators are not coincident. Moreover, the normal distance between theaxes 4c-4c 'is substantially equal to that between theaxes 2a-2b of the part {2} - The
figure 3e is a detail view that represents the profile of thepiece 4 whose pitch is identical to that of thepiece 3 but of different height - On the
figure 3f is schematized the three-dimensional compression line 3. The said hanger has a profile and a section of the same nature as those described for the articulatedhanger 4. However, for reasons of mechanical strength, the dimensions of the section may be different. In the same way, to respect the principle mentioned in the description attached to thefigure 1 , the distance between theaxes 3a-3b is twice that between theaxes 4a-4b - The
figure 3g is the schematic assembly of parts {2}, {3} & {4}. Said assembly realizes the principle described in the plate of the articulated device claimed.
