Description

La présente invention se rapporte au domaine des constructions et éléments de construction aux propriétés isolantes et plus particulièrement au domaine des éléments structurels aux propriétés isolantes.The present invention relates to the field of constructions and construction elements with insulating properties and more particularly to the field of structural elements with insulating properties.

Dans le cadre d'une optimisation de l'isolation thermique voire acoustique des constructions, il est courant de procéder à la pose de « murs manteaux » ou « Isolations Thermiques Extérieures » qui réalisent des couvertures additionnelles aux propriétés isolantes apposées contre la surface extérieure de certaines des parois des constructions. Cependant, l'installation de ces éléments de couvertures sur des parois de construction impose aux intervenants des opérations supplémentaires sur le chantier et donc des manipulations et du temps de travail pour mettre en place ces éléments sur les structures en construction de bâtiments.In the context of optimizing the thermal or even acoustic insulation of buildings, it is common to proceed with the installation of "mantle walls" or "External Thermal Insulation" which create additional covers with insulating properties affixed against the exterior surface of the building. some of the building walls. However, the installation of these roofing elements on construction walls imposes additional operations on the site and therefore manipulations and working time to set up these elements on the structures under construction of buildings.

Pour limiter cette problématique, des panneaux préfabriqués ont été développés qui présentent la forme d'un châssis et intègrent dans leurs épaisseurs différents matériaux aux propriétés isolantes. Toutefois, ces panneaux présentent une structure essentiellement formée de matériaux isolants à la rigidité limitée. Aussi, de tels panneaux n'autorisent pas leur utilisation comme structures porteuses mais essentiellement, sinon uniquement, sous la forme de bardages isolants préfabriqués et appliqués contre des parois de constructions.To limit this problem, prefabricated panels have been developed which have the shape of a frame and integrate in their thickness different materials with insulating properties. However, these panels have a structure essentially formed of insulating materials with limited rigidity. Also, such panels do not allow their use as load-bearing structures but essentially, if not solely, in the form of prefabricated insulating cladding applied against building walls.

La présente invention a pour but de pallier cet inconvénient en proposant une solution de construction qui permette de profiter des avantages apportés par les propriétés isolantes de matériaux en les intégrant aux structures porteuses des constructions de bâtiments en dépit des limites de rigidité de ces matériaux isolants.The present invention aims to overcome this drawback by proposing a construction solution which makes it possible to take advantage of the advantages provided by the insulating properties of materials by integrating them into the load-bearing structures of building constructions despite the rigidity limits of these insulating materials.

L'invention a ainsi pour objet un prémur comprenant au moins deux panneaux disposés dans des plans respectifs et sensiblement parallèles entre eux, les panneaux étant maintenus écartés par au moins une armature de jonction qui coopère avec au moins une face de chacun des panneaux pour réaliser un volume intérieur du prémur apte et destiné à une opération de coffrage, caractérisé en ce que au moins un des panneaux comprend au moins une plaque formée par association de matériaux répartis sur au moins deux couches superposées réalisées par, d'une part, des éléments structurels et, d'autre part, de matériaux aux propriétés isolantes acoustiquement et/ou thermiquement intégrant une inertie thermique ou une résistance au feu.The invention thus relates to a double wall comprising at least two panels arranged in respective planes and substantially parallel to each other, the panels being held apart by at least one junction reinforcement which cooperates with at least one face of each of the panels to produce an interior volume of the double wall suitable and intended for a formwork operation, characterized in that at least one of the panels comprises at least one plate formed by association of materials distributed over at least two superposed layers produced by, on the one hand, structural elements and, on the other hand, materials with acoustically and/or thermally insulating properties integrating thermal inertia or fire resistance.

L'invention a également pour objet une construction comprenant au moins un prémur selon l'invention.The invention also relates to a construction comprising at least one double wall according to the invention.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • [Fig. 1] est une représentation schématique d'un prémur et des différents éléments ou parties qui composent ce prémur,
  • [Fig. 2] est une représentation schématique d'un premier exemple d'arrangement d'un panneau dans un prémur selon l'invention,
  • [Fig. 3] est une représentation schématique d'un second exemple d'arrangement d'un panneau dans un prémur selon l'invention.
The invention will be better understood, thanks to the description below, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which:
  • [ Fig. 1 ] is a schematic representation of a double wall and the different elements or parts that make up this double wall,
  • [ Fig. 2 ] is a schematic representation of a first example of arrangement of a panel in a double wall according to the invention,
  • [ Fig. 3 ] is a schematic representation of a second example of arrangement of a panel in a double wall according to the invention.

Dans le présent document, il convient de comprendre le terme panneau comme se rapportant à tout élément de construction sensiblement plan et intégrant une ou plusieurs parois. A titre d'exemple, un panneau est ainsi susceptible de se rapporter à toute structure sensiblement plane par exemple en bois, en béton ou en matériau composite ou à toute structure assimilable à un tel arrangement plan.In this document, the term panel should be understood as referring to any substantially planar construction element integrating one or more walls. By way of example, a panel is thus likely to relate to any substantially flat structure, for example made of wood, concrete or composite material, or to any structure comparable to such a flat arrangement.

L'invention concerne à un prémur comprenant au moins deux panneaux 1, 2 disposés dans des plans respectifs et sensiblement parallèles entre eux, les panneaux 1, 2 étant maintenus écartés par au moins une armature de jonction 3 qui coopère avec au moins une face de chacun des panneaux 1, 2 pour réaliser un volume intérieur 4 du prémur apte et destiné à une opération de coffrage, caractérisé en ce que au moins un des panneaux 1, 2 comprend au moins une plaque formée par association de matériaux répartis sur au moins deux couches superposées réalisées par, d'une part, des éléments structurels 5 et, d'autre part, de matériaux 6 aux propriétés isolantes acoustiquement et/ou thermiquement intégrant une inertie thermique ou une résistance au feu. Selon un exemple de réalisation préféré, les éléments structurels 5 de la plaque intégrant des matériaux isolants 6 sont réalisés en bois, en métal, en acier ou en matériau composite apte à apporter une rigidité structurelle à la plaque et au panneau 1, 2 qui l'intègre. Les matériaux isolants 6 susceptibles d'être utilisés sont notamment la laine de bois, la laine de roche, la laine de verre, la laine de chanvre, le polystyrène et/ou leurs équivalents, ainsi qu'un mélange de ces matériaux.The invention relates to a double wall comprising at least two panels 1, 2 arranged in respective planes and substantially parallel to each other, the panels 1, 2 being held apart by at least one junction reinforcement 3 which cooperates with at least one face of each of the panels 1, 2 to produce an interior volume 4 of the double wall suitable and intended for a formwork operation, characterized in that at least one of the panels 1, 2 comprises at least one plate formed by combining materials distributed over at least two superposed layers produced by, on the one hand, structural elements 5 and, on the other hand, materials 6 with acoustically and/or thermally insulating properties incorporating thermal inertia or fire resistance. According to a preferred embodiment, the structural elements 5 of the plate integrating materials insulators 6 are made of wood, metal, steel or a composite material capable of providing structural rigidity to the plate and to the panel 1, 2 which incorporates it. The insulating materials 6 that can be used are in particular wood wool, rock wool, glass wool, hemp wool, polystyrene and/or their equivalents, as well as a mixture of these materials.

La réalisation d'un tel prémur selon l'invention permet de proposer un élément de construction intégrant des matériaux isolants 6 et dont la rigidité est suffisante pour assurer des opérations de coulage et coffrage d'un matériau hydraulique de type béton ou équivalent coulé dans le volume intérieur 4 entre les deux panneaux 1, 2 du prémur. Le prémur de l'invention forme ainsi un élément de construction comprenant des matériaux isolants 6 dans lequel un ou plusieurs matériaux destinés à réaliser la structure porteuse du bâtiment en construction est en mesure d'être intégré. Les matériaux isolants 6, après coffrage, se trouve intimement associés aux matériaux porteurs du bâtiment.The realization of such a double wall according to the invention makes it possible to propose a construction element integrating insulating materials 6 and whose rigidity is sufficient to ensure operations of pouring and formwork of a hydraulic material of concrete type or equivalent poured in the interior volume 4 between the two panels 1, 2 of the double wall. The double wall of the invention thus forms a construction element comprising insulating materials 6 in which one or more materials intended to produce the load-bearing structure of the building under construction can be integrated. The insulating materials 6, after formwork, are intimately associated with the supporting materials of the building.

Selon un exemple de réalisation préférée, les surfaces coffrantes de chacun des panneaux 1, 2 du prémur sont réalisés par des matériaux structurellement rigides de façon à assurer une résistance à la déformation sous l'effet de la pression exercée par les matériaux hydrauliques coulés dans le volume intérieur 4 du prémur lors de l'opération de coffrage.According to a preferred embodiment, the formwork surfaces of each of the panels 1, 2 of the double wall are made of structurally rigid materials so as to ensure resistance to deformation under the effect of the pressure exerted by the hydraulic materials cast in the interior volume 4 of the double wall during the formwork operation.

Selon un exemple particulier de réalisation du prémur selon l'invention, dans la plaque du panneau 1, 2, les couches superposées d'éléments structurels 5 et de matériaux isolants 6 sont disposées de façon alternée. Cet arrangement permet de réaliser une optimisation de la répartition des matériaux au travers de l'épaisseur de la plaque concernée, en fonction de leurs rigidités respectives, de façon à obtenir une plaque dont la superposition en alternance de couches de matériaux structurels 5 et isolants 6 conduise à une rigidité homogénéisée dans son épaisseur. Selon un exemple particulier, les éléments structurels 5 sont réalisés en bois afin d'optimiser les qualités bas-carbone de la plaque. L'arrangement alterné d'éléments structurels en bois 5 et de matériaux isolants 6 thermiquement permet de profiter des avantages propres au bois tout en optimisant la résistance au feu de la plaque en dépit de l'intégration d'un matériau bois, grâce aux propriétés ignifuges propres aux matériaux isolants 6 intercalés dans l'épaisseur de la plaque du panneau 1, 2.According to a particular embodiment of the double wall according to the invention, in the plate of the panel 1, 2, the superposed layers of structural elements 5 and of insulating materials 6 are arranged alternately. This arrangement makes it possible to achieve an optimization of the distribution of the materials through the thickness of the plate concerned, according to their respective rigidities, so as to obtain a plate whose alternating superposition of layers of structural materials 5 and insulating materials 6 leads to a homogenized rigidity in its thickness. According to a particular example, the structural elements 5 are made of wood in order to optimize the low-carbon qualities of the plate. The alternating arrangement of wooden structural elements 5 and thermally insulating materials 6 makes it possible to take advantage of the advantages specific to wood while optimizing the fire resistance of the plate despite the integration of a wood material, thanks to the properties flame retardants specific to insulating materials 6 interposed in the thickness of the plate of the panel 1, 2.

Selon un autre exemple particulier de réalisation du prémur susceptible d'être combiné avec l'exemple précédemment détaillé, les éléments structurels 5 de la plaque sont réalisés sous la forme de lames 51, les axes respectifs de lames 51 disposées dans une même couche de la plaque étant orientés d'une façon sensiblement parallèle entre eux. Cet arrangement particulier des lames 51 des éléments structurels 5 permet, d'une part, d'alléger le poids de la plaque en positionnant des espacements entre deux lames 51 consécutives et, d'autre part, de permettre l'insertion de matériaux isolants 6 dans l'espace existant entre des lames 51 consécutives. Selon un exemple de mise en œuvre, les lames 51 sont montées sur un cadre 52 dont les dimensions correspondent sensiblement aux dimensions de la plaque et/ou du panneau 1, 2 du prémur de l'invention.According to another particular embodiment of the double wall capable of being combined with the previously detailed example, the structural elements 5 of the plate are made in the form of strips 51, the respective axes of strips 51 arranged in the same layer of the plate being oriented substantially parallel to each other. This particular arrangement of the blades 51 of the structural elements 5 makes it possible, on the one hand, to lighten the weight of the plate by positioning spaces between two consecutive blades 51 and, on the other hand, to allow the insertion of insulating materials 6 in the space between consecutive blades 51. According to an example of implementation, the blades 51 are mounted on a frame 52 whose dimensions correspond substantially to the dimensions of the plate and/or of the panel 1, 2 of the double wall of the invention.

Selon un autre exemple qui réalise une variante spécifique de cet exemple particulier, les lames 51 des éléments structurels 5 de la plaque disposées dans des couches différentes de la plaque d'un panneau 1, 2 comprennent des axes respectifs orientés d'une façon non-parallèle entre eux. En cas de forces supportées par la plaque selon un axe sensiblement perpendiculaire au plan du panneau 1, 2, par exemple sous l'effet du poids du matériau hydraulique coulé lors de l'opération de coffrage, les forces en tension supportées au niveau de la plaque se trouvent réparties le long des axes des différentes lames 51 qui composent chacune des couches de la plaque. Aussi, selon cet arrangement, lorsque les axes des lames 51 positionnées dans des couches différentes sont orientés de façon non-parallèles, voire notamment de façon perpendiculaire, les forces de tension dans l'épaisseur de la plaque sont orientés selon des directions différentes d'une couche à l'autre, les forces de tensions supportées dans l'épaisseur de la plaque se trouve ainsi réparties selon différentes direction du plan de la plaque, de sorte que la résistance de la plaque se trouve optimisée et le risque de déformation de la plaque réduite.According to another example which realizes a specific variant of this particular example, the blades 51 of the structural elements 5 of the plate arranged in different layers of the plate of a panel 1, 2 comprise respective axes oriented in a non- parallel between them. In the event of forces supported by the plate along an axis substantially perpendicular to the plane of the panel 1, 2, for example under the effect of the weight of the hydraulic material poured during the formwork operation, the tensile forces supported at the level of the plate are distributed along the axes of the different blades 51 which make up each of the layers of the plate. Also, according to this arrangement, when the axes of the blades 51 positioned in different layers are oriented in a non-parallel way, or even in particular in a perpendicular way, the tension forces in the thickness of the plate are oriented in different directions from one layer to another, the tensile forces supported in the thickness of the plate are thus distributed according to different directions of the plane of the plate, so that the resistance of the plate is optimized and the risk of deformation of the reduced plaque.

Selon un autre exemple particulier de réalisation du prémur susceptible d'être combiné avec les différents exemples précédemment détaillés, le panneau 1, 2 comprend également au moins une couche d'un parement 7 recouvrant au moins partiellement la plaque formée par superposition d'éléments structurels 5 et de matériaux isolants 6. Cette couche de parement 7 réalise la surface extérieure du panneau 1, 2 et est positionné sur la face opposée du panneau 1, 2 par rapport au volume intérieur 4 du prémur destiné à permettre un coffrage de matériaux hydrauliques. Selon un exemple de réalisation, cette couche de parement 7 est réalisée par une paroi sensiblement rigide montée sur une plaque d'éléments structurels 5 et isolants 6 superposés. Selon un exemple de réalisation alternatif ou complémentaire, cette couche de parement 7 est réalisée par au moins un enduit déposé directement sur une plaque d'éléments structurels 5 et isolants 6 superposés, ou indirectement sur une paroi support réalisée par la surface d'une plaque intermédiaire positionnée entre la couche d'enduit et la plaque assemblant des éléments structurels 5 et isolants 6 superposés.According to another particular embodiment of the double wall capable of being combined with the various previously detailed examples, the panel 1, 2 also comprises at least one layer of a facing 7 covering at least partially the plate formed by superposition of structural elements. 5 and insulating materials 6. This facing layer 7 forms the outer surface of the panel 1, 2 and is positioned on the opposite face of the panel 1, 2 with respect to the interior volume 4 of the double wall intended to allow formwork of hydraulic materials. According to an exemplary embodiment, this facing layer 7 is produced by a substantially rigid wall mounted on a plate of structural elements 5 and insulating elements 6 superimposed. According to an alternative or complementary embodiment, this facing layer 7 is produced by at least one coating deposited directly on a plate of structural elements 5 and insulating elements 6 superimposed, or indirectly on a support wall produced by the surface of a plate intermediate positioned between the coating layer and the plate assembling structural elements 5 and insulating 6 superimposed.

Selon un autre exemple qui réalise une variante spécifique de cet exemple particulier, le panneau 1, 2 comprend également au moins une couche d'un matériau aux propriétés isolantes intercalée entre la couche de parement 7 et la plaque formée par superposition d'éléments structurels 5 et de matériaux isolants 6. Cette couche supplémentaire aux propriétés isolantes permet ainsi d'accentuer l'optimisation des propriétés du prémur en matière d'isolation au regard des éventuelles agressions et intempéries extérieures susceptibles d'être supportées au niveau de la couche de parement. Par ailleurs, en étant positionné au niveau d'une face non-coffrante du panneau 1, 2, les matériaux aux propriétés isolantes de la couche supplémentaire ne sont pas en mesure d'altérer la résistance du panneau 1, 2 à la pression exercée par le matériau hydraulique coulé dans le volume intérieur 4 du prémur et donc de dégrader la qualité du coffrage par le prémur de l'invention.According to another example which realizes a specific variant of this particular example, the panel 1, 2 also comprises at least one layer of a material with insulating properties interposed between the facing layer 7 and the plate formed by superposition of structural elements 5 and insulating materials 6. This additional layer with insulating properties thus makes it possible to accentuate the optimization of the properties of the double wall in terms of insulation with regard to possible attacks and external bad weather likely to be supported at the level of the facing layer. Furthermore, by being positioned at the level of a non-forming face of the panel 1, 2, the materials with insulating properties of the additional layer are not able to alter the resistance of the panel 1, 2 to the pressure exerted by the hydraulic material poured into the interior volume 4 of the double wall and therefore to degrade the quality of the formwork by the double wall of the invention.

Cet arrangement permet de proposer un prémur aux propriétés d'isolation optimisées au niveau de chacune de ses faces tout en assurant une résistance mécanique structurelle par le matériau hydraulique de type béton ou équivalent coulé et coffré dans le volume intérieur 4 réalisé entre les deux panneaux 1, 2 du prémur.According to another particular embodiment of the double wall capable of being combined with the various previously detailed examples, the double wall is produced by two panels 1, 2 respectively formed from at least one plate formed by combining materials distributed over at least two superposed layers produced by, on the one hand, structural elements 5 and, on the other hand, materials 6 with acoustically and/or thermally insulating properties incorporating thermal inertia or fire resistance. This arrangement makes it possible to propose a double wall with optimized insulation properties at the level of each of its faces while ensuring structural mechanical resistance by the hydraulic material of the concrete type or equivalent poured and cased in the interior volume 4 produced between the two panels 1 , 2 of the forewall.

Selon un autre exemple particulier de réalisation du prémur susceptible d'être combiné avec certains des différents exemples précédemment détaillés, le prémur est réalisé par deux panneaux 1, 2 et dont le second des panneaux est réalisé à partir d'au moins un matériau de type béton.

According to this arrangement, the panel of the double wall which incorporates a material of the concrete type, on the one hand, participates in the quality of the formwork in particular by resisting the risk of deformation of the panel under the effect of the pressure exerted by the hydraulic materials cast in the interior volume 4 of the double wall, on the other hand, completes the structural mechanical strength provided by the hydraulic material of the concrete or equivalent type cast and cased in the interior volume 4 of the double wall.

Selon un exemple de réalisation préférée susceptible d'être combiné avec les différents exemples précédemment détaillés, les différents éléments que comporte le panneau sont assemblés entre eux par des moyens d'assemblage choisis parmi la liste comprenant une colle, des boulons, des agrafes, des vis, des pointes, ou tout moyen équivalent.According to an example of a preferred embodiment capable of being combined with the various examples detailed above, the various elements that comprise the panel are assembled together by assembly means chosen from the list comprising glue, bolts, staples, screws, nails, or any equivalent means.

Selon cette variante de construction, le prémur de l'invention est intégré à la construction de sorte que la résistance aux variations de température ou d'incendie mais également aux agressions sonores extérieures soit optimisée.According to a particular embodiment of the construction, a double wall is arranged in the construction so that a panel 1, 2 of the double wall comprising at least one plate formed by combining materials distributed over at least two superimposed layers produced by, on the one hand, structural elements 5 and, on the other hand, materials with acoustically and/or thermally insulating properties 6 integrating thermal inertia or fire resistance is positioned on the side facing the exterior of the construction.

Selon cette variante de construction, le prémur de l'invention est intégré à la construction de sorte que la résistance aux variations de température ou d'incendie mais également aux agressions sonores intérieures soit optimale, notamment lorsque le prémur de l'invention est positionné entre deux volumes intérieurs d'une construction et dont l'un de ces volumes est, par exemple, destiné à une application sonore et/ou thermique particulière.According to another particular embodiment of the construction capable of being combined with the previously detailed example, the double wall is arranged in the construction so that a panel 1, 2 of the double wall comprising at least one plate formed by combining materials distributed over at least two superposed layers produced by, on the one hand, structural elements 5 and, on the other hand, of materials with acoustically and/or thermally insulating properties 6 incorporating thermal inertia or fire resistance is positioned on the side facing the interior of the construction.
