Description

Brique de construction garnie d'une matière poreuse silico-calcaire  Building brick with porous silico-limestone material
La présente invention a pour objet un élément de construction de forme générale parallélépipédique comprenant une matière poreuse silico-calcaire et pouvant être utilisée dans la construction d'un mur. The present invention relates to a construction element of parallelepipedal general shape comprising a porous silico-limestone material and can be used in the construction of a wall.
Les briques en terre cuite, dites « monomur », ou en ciment, dites « parpaing », à structure alvéolaire, sont largement utilisées pour la construction de murs, de sols, de cloisons ou autres éléments de bâtiments.  Terracotta bricks, called "monomur", or cement, called "cinderblock", honeycomb structure, are widely used for the construction of walls, floors, partitions or other elements of buildings.
Ces briques sont habituellement composées d'alvéoles vides (non remplies) plus ou moins grandes, de forme plus ou moins différentes, destinées à augmenter l'isolation thermique. Ces structures sont composées d'alvéoles de taille réduite pour limiter la convection thermique et présentent de faibles épaisseurs de parois pour limiter l'effet de conduction.  These bricks are usually composed of empty cells (not filled) more or less large, more or less different shape, to increase the thermal insulation. These structures are composed of cells of reduced size to limit thermal convection and have low wall thicknesses to limit the conduction effect.
L'espace intérieur des alvéoles de ces briques de construction est généralement vide. Lorsqu'il existe un gradient de température au sein d'une alvéole, l'air contenu dans cette alvéole se déplace par convection. La conséquence directe est une diminution de la résistance thermique du système. Une des solutions mises en œuvre pour minimiser les effets convectifs consiste à augmenter le nombre d'alvéoles, mais cette solution est limitée par (i) une mise en œuvre technique des briques de plus en plus complexe, (ii) des quantités de matière plus importantes, (iii) l'apparition de phénomènes de conduction plus important.  The interior space of the cells of these building bricks is usually empty. When a temperature gradient exists within a cell, the air contained in this cell moves by convection. The direct consequence is a decrease in the thermal resistance of the system. One of the solutions implemented to minimize the convective effects is to increase the number of cells, but this solution is limited by (i) a technical implementation of bricks more and more complex, (ii) quantities of material more (iii) the appearance of more important conduction phenomena.
Pour limiter ce phénomène, il est possible de remplir ces alvéoles avec un matériau inorganique de faible conductivité thermique et ainsi empêcher ces mouvements convectifs. Le rôle de ce matériau inorganique est du fait de sa microstructure de donner une « tenue mécanique à l'air ou au vide », à savoir emprisonner l'air (ou le vide) de manière à minimiser les effets de convection.  To limit this phenomenon, it is possible to fill these cells with an inorganic material of low thermal conductivity and thus prevent these convective movements. The role of this inorganic material is due to its microstructure to give a "mechanical strength to air or vacuum", namely to trap air (or vacuum) so as to minimize the effects of convection.
A titre d'exemple, le document FR 2521 197 Al, fait mention de briques en terre cuite avec des alvéoles remplies « d'un matériaux cellulaire à haut pouvoir d'isolation thermique ». Les matériaux proposés pour le remplissage des alvéoles sont : « une mousse de polyuréthane, une mousse de polystyrène, ou tout autre matériaux fibreux (laine de verre ou de roche) ou divisé (agglomérat de liège) ». L'inconvénient de cette solution est l'utilisation de matériaux organiques et/ou inorganiques qui soient (i) peuvent mal se comporter face au risque d'incendie : tenue au feu, résistance au feu, émission(s) de gaz toxique(s) et de débris enflammés (ii) soit sont potentiellement dangereux car classifïables à termes dans la catégorie des FCR (Fibres Céramiques Réfractaires) nécessitant des conditions spécifiques de pose puis de gestion des déchets, (iii) soit perdre des propriétés d'isolation au cours du temps (tassement du garnissage, dégradation chimique des matériaux, ...), (iv) ne présentent pas ou peu de tenue mécanique (< 5 kg/cm2), (v) ne sont pas recyclables dans les filières traditionnelles, (vi) soit un mélange de points (i) à (vi). On peut également noter que dans certains cas le garnissage se fait sur place pendant le chantier, cela est une contrainte et nécessite de la main d'œuvre supplémentaire. By way of example, document FR 2521 197 A1 mentions terracotta bricks with cavities filled with "cellular materials with high thermal insulation". The materials proposed for the filling of the cells are: "a polyurethane foam, a polystyrene foam, or any other fibrous material (glass wool or rock) or divided (cork agglomerate)". The disadvantage of this solution is the use of organic and / or inorganic materials which are (i) may behave badly in the face of the risk of fire: fire resistance, fire resistance, emission (s) of toxic gas (s) ) and flaming debris (ii) are potentially dangerous because they are classifiable in terms of the RCF (Refractory Ceramics Fibers) category requiring specific conditions for the laying and subsequent management of waste, or (iii) to lose insulation properties during time (packing compaction, chemical degradation of materials, ...), (iv) have little or no mechanical strength (<5 kg / cm 2 ), (v) are not recyclable in traditional channels, ( vi) a mixture of points (i) to (vi). It can also be noted that in some cases the lining is done on site during the construction, this is a constraint and requires additional labor.
Le document FR 2 876 400 décrit quant à lui l'utilisation de briques creuses remplie « avec un matériau isolant à base de produit(s) poreux en vrac ». La matière dite naturelle pour le garnissage est à base de perlite expansée ou de la vermiculite expansée dans laquelle on utilise l'amidon comme épaississant. Ce document fait également mention de l'utilisation d'autres composants comme de la silice colloïdale, des agents hydrophobes, ou du plastique dispersé.  The document FR 2 876 400 describes the use of hollow bricks filled "with an insulating material based on porous product (s) in bulk". The so-called natural material for filling is based on expanded perlite or expanded vermiculite in which starch is used as a thickener. This document also mentions the use of other components such as colloidal silica, hydrophobic agents, or dispersed plastic.
L'inconvénient de cette solution est la faible tenue mécanique des agglomérats, cela entraînant un risque de détérioration de ces masses de garnissage pendant le transport et le montage de ces éléments. Il est à noter le faible pouvoir cohésif de cette structure induisant notamment des risques de perte de matière lors de perçage, de découpe, ... des murs par exemple. Il est à noter également le tassement des grains plusieurs années après la pose des éléments de construction, ce qui entraîne à terme la diminution du pouvoir isolant. Egalement l'emploi de liants organiques ou d'agent hydrophobe diminue sensiblement la résistance thermique de ces matériaux et accroît le risque de tenue au feu.  The disadvantage of this solution is the low mechanical strength of the agglomerates, which entails a risk of deterioration of these packing masses during transport and assembly of these elements. It should be noted the low cohesive power of this structure inducing particular risks of loss of material during drilling, cutting, ... walls for example. It is also worth noting the settlement of the grains several years after the laying of the building elements, which ultimately leads to the reduction of the insulating power. Also the use of organic binders or hydrophobic agent substantially reduces the thermal resistance of these materials and increases the risk of fire resistance.
Sur le même principe, on peut citer le document FR2 927 623 Al qui divulgue des éléments de construction de type brique en terre cuite, garnie d'une mousse de chaux. Cette matière poreuse est constituée d'un mélange chaux-ciment 65 à 90% de la matière sèche, de fibres, de charges minérales, d'un durcisseur et d'un agent moussant. Le principe est de faire prendre de la chaux avec un agent moussant pour créer des bulles d'air, de les emprisonner lors de la réaction et avoir ainsi une structure poreuse.  On the same principle, one can quote the document FR2 927 623 A1 which discloses elements of brick-type construction in terracotta, lime-filled with foam. This porous material consists of a mixture lime-cement 65 to 90% of the dry matter, fibers, mineral fillers, a hardener and a foaming agent. The principle is to get lime with a foaming agent to create air bubbles, to trap them during the reaction and thus have a porous structure.
Une telle structure présente le désavantage d'avoir une tenue mécanique faible, ce qui limite la réduction du nombre de parois de la brique de terre cuite et entraîne des risques de dégradation de la matière poreuse pendant la pose des éléments de construction. Autrement dit, l'inconvénient de toutes les solutions présentées ci-dessus est la faible résistance mécanique à la compression du matériau isolant. Ceci implique la nécessité d'assurer la tenue mécanique d'une brique de construction uniquement par les tessons et ne permet pas d'en réduire la quantité ou la section en deçà d'une certaine limite. Such a structure has the disadvantage of having a low mechanical strength, which limits the reduction of the number of walls of the clay brick and entails risks of degradation of the porous material during the laying of the building elements. In other words, the disadvantage of all the solutions presented above is the low compressive strength of the insulating material. This implies the need to ensure the mechanical strength of a building brick only by the shards and does not reduce the amount or section within a certain limit.
Partant de là, un problème qui se pose est de fournir une brique de construction comprenant un matériau isolant ayant une résistance mécanique suffisante pour participer à la résistance à la compression de la brique.  From there, a problem arises to provide a building block comprising an insulating material having sufficient strength to participate in the compressive strength of the brick.
Une solution de la présente invention est un élément de construction de forme générale parallélépipédique comprenant au moins deux alvéoles délimitées par des tessons intérieurs et des tessons périphériques, débouchant sur une première face et une deuxième face opposées du parallélépipède et comprenant une matière poreuse silico-calcaire, la première et la deuxième face du parallélépipède étant chacune caractérisée par :  A solution of the present invention is a construction element of generally parallelepipedal shape comprising at least two cells delimited by internal sherds and peripheral shards, opening on a first opposite face and second face of the parallelepiped and comprising a porous silico-limestone material. the first and second faces of the parallelepiped being each characterized by:
deux arêtes orientées dans une première direction 1 et deux arêtes orientées dans une deuxième direction 2 ;  two edges oriented in a first direction 1 and two edges oriented in a second direction 2;
- un rapport entre la surface des tessons présents sur ladite face du parallélépipède et la surface totale de cette même face du parallélépipède, compris entre 35 et 45%, et  a ratio between the surface of the sherds present on said face of the parallelepiped and the total surface of this same face of the parallelepiped, between 35 and 45%, and
- un rapport entre la longueur des tessons intérieurs orientés dans la première direction 1 et la longueur totale des tessons intérieurs de cette même face du parallélépipède, inférieur à 25%, préférentiellement moins de 10%.  - A ratio between the length of the internal sherds oriented in the first direction 1 and the total length of the internal sherds of the same face of the parallelepiped, less than 25%, preferably less than 10%.
La matière poreuse silico-calcaire présente une résistance mécanique suffisante pour participer à la résistance à la compression de l'élément de construction. Aussi, cette résistance à la compression permet de réduire la quantité de tessons et/ou leurs sections, et donc de réduire les effets de conduction thermique.  The porous silico-limestone material has sufficient mechanical strength to participate in the compressive strength of the construction element. Also, this compressive strength makes it possible to reduce the quantity of sherds and / or their sections, and thus to reduce the effects of thermal conduction.
D'autre part, cette matière poreuse silico-calcaire permet du fait de sa microstructure de donner une tenue mécanique à l'air ou au vide, à savoir emprisonner l'air (ou le vide) de manière à minimiser les effets de convection.  On the other hand, this porous silico-limestone material makes it possible, because of its microstructure, to give a mechanical strength to air or vacuum, namely to trap the air (or the vacuum) so as to minimize the effects of convection.

La matière poreuse utilisée dans l'invention est totalement inorganique ce qui lui confère d'excellentes propriétés en terme de résistance au feu (maintien des propriétés mécaniques à haute température), de réduction des émissions de produits toxiques en cas d'incendie, de réduction des émissions de poussières ou de fibres,... The porous material used in the invention is totally inorganic, which gives it excellent properties in terms of fire resistance (maintenance of properties high temperature mechanical), reduction of toxic emissions in case of fire, reduction of dust or fiber emissions, etc.
La matière poreuse remplit de préférence la totalité des espaces de la brique car cette dernière sert de moule lors de la mise en forme de l'isolant. Cela facilite le remplissage et permet d'éviter tout espace entre la brique et la matière poreuse, espace dans lequel l'air pourrait circuler par convection. Ceci pourrait entraîner une perte de performance d'isolation.  The porous material preferably fills all the spaces of the brick because the latter serves as a mold during the shaping of the insulation. This facilitates the filling and avoids any space between the brick and the porous material, space in which the air could circulate by convection. This could result in loss of insulation performance.
La pose de ces éléments de construction est facilitée par rapport aux isolants traditionnels car il fait partie intégrante de la brique. La pose est donc identique à celle d ' une brique non garnie .  The installation of these building elements is facilitated compared to traditional insulators because it is an integral part of the brick. The pose is therefore identical to that of an unpacked brick.
La matière poreuse utilisée permet également de réduire la transmission des ondes sonores à travers l'élément de construction. La transmission sonore est en générale réduite lors du passage entre deux matériaux de densité différente.  The porous material used also reduces the transmission of sound waves through the building element. The sound transmission is generally reduced when passing between two materials of different density.
Enfin, l'ensemble des matériaux utilisés dans l'élaboration de l'élément de construction selon l'invention sont naturelles et recyclables.  Finally, all the materials used in the construction of the building element according to the invention are natural and recyclable.
Les éléments de construction sont réalisés à partir d'argile extrudé pour lui donner la forme souhaitée. L'argile est un matériau constitué de feuillets qui s'orientent dans la direction de l'extrusion. La conductivité thermique des tessons d'argile est différente suivant la direction considérée : 0.54 W/m dans la direction 1 et 0.37 W/m dans la direction 2 (cf figures 1 et 2).  The building elements are made from extruded clay to give it the desired shape. Clay is a material consisting of leaflets that orient in the direction of extrusion. The thermal conductivity of the sherds of clay is different in the direction considered: 0.54 W / m in the direction 1 and 0.37 W / m in the direction 2 (see Figures 1 and 2).
Le transfert de la chaleur à travers la brique se fait majoritairement dans la direction 1, entre l'extérieur du bâtiment et l'intérieur. Deux modes de transferts sont prépondérants, la conduction à travers le matériau de la brique et la convection de l'air emprisonné dans les ouvertures de la brique.  The transfer of heat through the brick is mainly in the direction 1, between the outside of the building and the interior. Two modes of transfer are predominant, the conduction through the material of the brick and the convection of the air trapped in the openings of the brick.
Les briques présentées sur les deux exemples suivants se composent de terre cuite et sont garnies de matière poreuse inorganique. La terre cuite compose le corps de la brique et la matière poreuse inorganique remplie les alvéoles. Les dimensions des briques selon la direction 1 varient de 300 à 490 mm. Les surfaces de ces deux exemples sont aux environs de 43000 mm2, la modification porte sur l'architecture de la brique et par conséquent sur la répartition terre cuite (tessons)/matière poreuse. Le premier exemple (figure 1) montre une brique constituée de 7 rangés de 2 alvéoles 2a et 2b, séparées par des tessons parallèles 3 et 5, d'une épaisseur maximale de 15 mm pour une brique en terre cuite non poreuse et de 20 mm pour une brique en terre cuite poreuse. Les parois 4a et 6a n'excèdent également pas les valeurs précédemment citées. Le deuxième exemple (figure 2) montre une brique avec une architecture constituée de 8 rangés de 3 alvéoles 2a, 2b et 2c remplies de matière poreuse. Les alvéoles 2d ne contiennent pas de masse poreuse, elles sont présentent pour alléger la structure en terre cuite mais elles sont de trop faible dimension pour être remplies. Les tessons 3, 5, 4a, 4b, 6a, 6b, 7 et 8 ne doivent pas excéder 20 mm dans le cas de brique en terre cuite poreuse et 15 mm dans le cas de terre cuite non poreuse. Les tessons 6a et 6b entre alvéoles sont inclinés afin d'augmenter le parcours du flux thermique et ainsi de réduire la conductivité thermique dans la direction 1. The bricks presented in the following two examples are terracotta and are lined with porous inorganic material. Terracotta makes up the body of the brick and the porous inorganic material fills the cells. The dimensions of the bricks in direction 1 vary from 300 to 490 mm. The surfaces of these two examples are around 43000 mm 2 , the modification relates to the architecture of the brick and therefore the distribution terracotta (sherds) / porous material. The first example (Figure 1) shows a brick consisting of 7 rows of 2 cells 2a and 2b, separated by parallel shards 3 and 5, with a maximum thickness of 15 mm for a non-porous terracotta brick and 20 mm for a porous terracotta brick. The walls 4a and 6a also do not exceed the previously mentioned values. The second example (Figure 2) shows a brick with an architecture consisting of 8 rows of 3 cells 2a, 2b and 2c filled with porous material. The cells 2d do not contain a porous mass, they are present to lighten the terracotta structure but they are too small to be filled. Shards 3, 5, 4a, 4b, 6a, 6b, 7 and 8 must not exceed 20 mm in the case of porous clay brick and 15 mm in the case of non-porous terra cotta. The shards 6a and 6b between cells are inclined to increase the path of the heat flow and thus reduce the thermal conductivity in the direction 1.
Enfin la présente invention a également pour objet un mur comprenant un ou plusieurs éléments de construction selon l'invention, dans lequel la première direction 1 est orientée dans le sens de l'épaisseur du mur  Finally, the present invention also relates to a wall comprising one or more building elements according to the invention, wherein the first direction 1 is oriented in the direction of the thickness of the wall.
