Description

La présente invention concerne une construction réalisée à partir d'éléments préfabriqués empilés à sec en rangées superposées et comportant chacun deux faces d'extrémité pourvues d'un renfoncement, une face supérieure, une face inférieure, deux faces longitudinales, des cavités ayant un côté adjacent à l'une des faces longitudinales, et des alvéoles ayant un côté adjacent à l'autre face longitudinale, les alvéoles débouchant sur les faces supérieure et inférieure.The present invention relates to a construction made from prefabricated elements stacked dry in superimposed rows and each comprising two end faces provided with a recess, an upper face, a lower face, two longitudinal faces, cavities having one side. adjacent to one of the longitudinal faces, and cells having a side adjacent to the other longitudinal face, the cells opening onto the upper and lower faces.

Les éléments préfabriqués de ce type sont en général utilisés pour réaliser des murs dans lesquels leurs alvéoles sont tournées vers l'extérieur et ménagent des espaces creux renfermant de l'air servant d'agent d'isolation.Prefabricated elements of this type are generally used to make walls in which their cells face outwards and provide hollow spaces containing air serving as an insulating agent.

Comme ces éléments sont empilés à sec, il est nécessaire de crépir leur face longitudinale externe afin d'éviter des infiltrations d'eau de pluie ou une propagation de courants d'air au niveau de leurs surfaces de contact, et plus particulièrement au niveau de leurs faces d'extrémité.As these elements are stacked dry, it is necessary to plaster their external longitudinal face in order to avoid infiltration of rain water or the propagation of air currents at their contact surfaces, and more particularly at their end faces.

L'application d'un enduit extérieur a toutefois l'inconvénient d'augmenter de façon importante le prix de revient de la construction.The application of an exterior coating, however, has the disadvantage of significantly increasing the cost of construction.

La présente invention se propose de remédier aux inconvénients indiqués ci-dessus et, pour ce faire, elle a pour objet une construction réalisée à partir d'éléments préfabriqués du type précité, cette construction étant caractérisée en ce que les alvéoles comportent chacune un tronçon transversal s'étendant entre deux cavités adjacentes, les tronçons transversaux débouchant sur les faces supérieure et inférieure et ayant une section approximativement égale à celle d'un conduit délimité par les renfoncements de deux éléments adjacents d'une même rangée, en ce que les conduits délimités par les renfoncements de deux éléments successifs d'une même rangée sont situés chacun dans le prolongement de l'un des tronçons transversaux des alvéoles d'un élément de la rangée adjacente, et en ce qu'un liant coulé dans les conduits et les alvéoles relie entre eux les éléments empilés.The present invention proposes to overcome the drawbacks indicated above and, to do this, it relates to a construction made from prefabricated elements of the aforementioned type, this construction being characterized in that the cells each comprise a transverse section. extending between two adjacent cavities, the transverse sections opening onto the upper and lower faces and having a section approximately equal to that of a duct delimited by the recesses of two adjacent elements of the same row, in that the delimited ducts by the recesses of two successive elements of the same row are each located in the extension of one of the transverse sections of the cells of an element of the adjacent row, and in that a binder poured into the conduits and the cells connects the stacked elements together.

Grâce à la localisation particulière du liant, la construction conforme à l'invention est parfaitement étanche vis-à-vis de l'eau de pluie, de l'air ainsi que du bruit et du feu, même si elle n'est pas protégée par un enduit. Son prix de revient s'en trouve par conséquent réduit dans d'importantes proportions.Thanks to the specific location of the binder, the construction according to the invention is perfectly sealed against rainwater, air as well as noise and fire, even if it is not protected with a coating. Its cost price is therefore reduced significantly.

On précisera ici que le liant remplissant les tronçons transversaux des alvéoles assure la solidité de la construction alors que le liant remplissant les tronçons longitudinaux desdites alvéoles assure l'étanchéité recherchée.It will be specified here that the binder filling the transverse sections of the cells ensures the solidity of the construction while the binder filling the longitudinal sections of said cells provides the desired seal.

Lorsque l'on ne souhaite pas enduire les éléments préfabriqués pour abaisser le prix de revient de la construction, il convient d'utiliser des éléments préfabriqués ayant une finition particulièrement soignée pour conférer une bonne esthétique à la construction.When it is not desired to coat the prefabricated elements in order to lower the cost price of the construction, it is advisable to use prefabricated elements having a particularly careful finish to impart good aesthetics to the construction.

De préférence, les éléments préfabriqués comportent deux alvéoles dont les tronçons transversaux sont équidistants des faces d'extrémité desdits éléments et trois cavités situées l'une entre les tronçons transversaux et les deux autres entre un tronçon transversal et la face d'extrémité adjacente à ce tronçon.Preferably, the prefabricated elements comprise two cells whose transverse sections are equidistant from the end faces of said elements and three cavities located one between the transverse sections and the other two between a transverse section and the end face adjacent to this. section.

Selon un mode de réalisation particulier de l'invention, les éléments préfabriqués comportent une paroi intermédiaire divisant chacun des tronçons transversaux de leurs alvéoles en deux parties et s'étendant entre leurs faces supérieure et inférieure, ainsi qu'une protubérance d'extrémité faisant saillie sur le fond de chacun de leurs renfoncements, parallèlement à leurs faces longitudinales, ces protubérances étant dans le prolongement les unes des autres et ayant une hauteur égale à la profondeur des renfoncements correspondants.According to a particular embodiment of the invention, the prefabricated elements comprise an intermediate wall each dividing the transverse sections of their cells in two parts and extending between their upper and lower faces, as well as a protruding end protruding on the bottom of each of their recesses, parallel to their longitudinal faces, these protrusions being in the extension of each other and having a height equal to the depth of the corresponding recesses.

Les parois intermédiaires et les protubérances d'extrémité permettent la formation, à l'intérieur de la construction, de conduits verticaux situés du côté opposé aux tronçons longitudinaux des alvéoles.The intermediate walls and the end protrusions allow the formation, inside the construction, of vertical conduits situated on the side opposite to the longitudinal sections of the cells.

Or, grâce à ces conduits, la construction présente deux avantages particuliers.However, thanks to these conduits, the construction has two particular advantages.

Tout d'abord, lorsque les faces longitudinales des éléments préfabriqués qui sont opposées aux tronçons longitudinaux des alvéoles constituent la face extérieure de la construction et ne sont pas enduites, l'eau de pluie qui parviendrait par capillarité jusqu'aux conduits verticaux précités serait évacuée par ces derniers à la partie inférieure de la construction. Ces conduits verticaux, en s'ajoutant aux conduits verticaux ménagés par les cavités, exceptionnellement dépourvus de fond, des éléments préfabriqués contribuent donc à mieux protéger la construction contre une propagation de l'eau de pluie à l'intérieur de cette dernière.First of all, when the longitudinal faces of the prefabricated elements which are opposite to the longitudinal sections of the cells constitute the external face of the construction and are not coated, the rain water which would arrive by capillarity to the aforementioned vertical conduits would be evacuated by these at the bottom of the construction. These vertical conduits, in addition to the vertical conduits formed by the cavities, exceptionally devoid of bottom, prefabricated elements therefore contribute to better protect the construction against the propagation of rainwater inside the latter.

Par ailleurs, la présence des conduits verticaux formés par les parois intermédiaires et les protubérances d'extrémité permettent de réduire la quantité de liant nécessaire à la solidarisation des éléments préfabriqués, et par conséquent d'abaisser de façon non négligeable le prix de revient de la construction.Furthermore, the presence of the vertical conduits formed by the intermediate walls and the end protrusions make it possible to reduce the quantity of binder necessary for the joining of the prefabricated elements, and consequently to significantly reduce the cost price of the construction.

De préférence, les parois intermédiaires situées dans les tronçons transversaux des alvéoles sont dans le prolongement des protubérances d'extrémité situées dans les renfoncements.Preferably, the intermediate walls located in the transverse sections of the cells are in the extension of the end protrusions located in the recesses.

La présente invention concerne également les éléments préfabriqués entrant dans la constitution de la construction précitée.The present invention also relates to the prefabricated elements forming part of the construction of the aforementioned construction.

Deux modes d'exécution de la présente invention seront décrits ci-après à titre d'exemples nullement limitatifs en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de dessus d'un élément préfabriqué conforme à l'invention ;
  • la figure 2 est une vue de face partiellement en coupe de l'élément préfabriqué, la coupe étant effectuée selon la ligne II-II de la figure 1 ;
  • la figure 3 est une vue en coupe selon la ligne III-III de la figure 1 ;
  • la figure 4 est une vue partielle en perspective d'une construction réalisée à partir d'éléments préfabriqués ayant la structure de celui représenté sur les figures 1 à 3 ;
  • la figure 5 est une vue de dessus d'un élément préfabriqué selon une variante de réalisation ; et
  • la figure 6 est une vue partielle en perspective d'une construction réalisée à partir d'éléments préfabriqués identiques à celui représenté sur la figure 5.
Two embodiments of the present invention will be described below by way of non-limiting examples with reference to the accompanying drawings in which:
  • Figure 1 is a top view of a prefabricated element according to the invention;
  • Figure 2 is a front view partially in section of the prefabricated element, the section being taken along line II-II of Figure 1;
  • Figure 3 is a sectional view along line III-III of Figure 1;
  • Figure 4 is a partial perspective view of a construction made from prefabricated elements having the structure of that shown in Figures 1 to 3;
  • Figure 5 is a top view of a prefabricated element according to an alternative embodiment; and
  • FIG. 6 is a partial perspective view of a construction produced from prefabricated elements identical to that shown in FIG. 5.

L'élément préfabriqué A que l'on peut voir sur les figures 1 à 3 a une forme générale parallélépipédique et comprend deux faces d'extrémité 1 pourvues chacune d'un renfoncement 2, une face supérieure 3, une face inférieure 4, deux faces longitudinales 5,6, trois cavités 7 ayant chacune un côté adjacent à la face longitudinale 5 et deux alvéoles 8 ayant chacune un tronçon longitudinal adjacent à la face longitudinale 6.The prefabricated element A which can be seen in FIGS. 1 to 3 has a generally parallelepiped shape and comprises two end faces 1 each provided with a recess 2, an upper face 3, a lower face 4, two faces longitudinal 5,6, three cavities 7 each having a side adjacent to the longitudinal face 5 and two cells 8 each having a longitudinal section adjacent to the longitudinal face 6.

Conformément à l'invention, les alvéoles 8 comportent également un tronçon transversal 8a communiquant avec leur tronçon longitudinal et s'étendant entre deux cavités adjacentes 7. Les tronçons transversaux 8a des alvéoles débouchent sur les faces supérieure 3 et inférieure 4 de l'élément A et ont une section approximativement égale à celle d'un conduit 9 qui est représenté sur la figure 4, chaque conduit 9 étant délimité entre deux éléments A disposés bout à bout, par les renfoncements 2 des faces d'extrémité en contact de ces éléments.According to the invention, the cells 8 also comprise a transverse section 8a communicating with their longitudinal section and extending between two adjacent cavities 7. The transverse sections 8a of the cells open onto the upper 3 and lower 4 faces of the element A and have a section approximately equal to that of a duct 9 which is shown in FIG. 4, each duct 9 being delimited between two elements A arranged end to end, by the recesses 2 in the end faces in contact with these elements.

Dans l'exemple de réalisation représenté, les cavités 7 ont une section carrée et ont un fond dont la face inférieure est dans le plan de la face inférieure 4 de l'élément A. Il va de soi cependant qu'elles pourraient avoir une section de forme différente et être dépourvue de fond, c'est-à-dire déboucher aussi bien sur la face supérieure 3 que sur la face inférieure 4.In the embodiment shown, the cavities 7 have a square section and have a bottom, the underside of which is in the plane of the underside 4 of the element A. It goes without saying, however, that they could have a section of different shape and be devoid of bottom, that is to say lead to both the upper face 3 and the lower face 4.

On notera par ailleurs que les alvéoles 8 ont une section en forme de T dont la barre transversale est plus longue d'un côté que de l'autre, ce qui n'est toutefois pas obligatoire, et que les différentes parois de l'élément A peuvent avoir des épaisseurs identiques ou différentes.Note also that the cells 8 have a T-shaped section whose crossbar is longer on one side than the other, which is not however mandatory, and that the different walls of the element A can have identical or different thicknesses.

En se référant maintenant à la figure 4, on peut voir une partie d'un mur constitué d'éléments préfabriqués A empilés à sec en rangées superposées horizontales.Referring now to Figure 4, we can see part of a wall made of prefabricated elements A dry stacked in horizontal overlapping rows.

Les éléments A de deux rangées successives sont décalés les uns par rapport aux autres de telle sorte que les conduits 9 ménagés entre deux éléments A successifs d'une même rangée soient situés chacun dans le prolongement de l'un des tronçons transversaux 8a des alvéoles 8 d'un élément A de la rangée immédiatement adjacente.The elements A of two successive rows are offset with respect to each other so that the conduits 9 formed between two successive elements A of the same row are each located in the extension of one of the transverse sections 8a of the cells 8 of an element A of the immediately adjacent row.

Les éléments constituant le mur sont solidarisés par un liant tel que du mortier ou tout autre matériau équivalent remplissant les conduits 9 et les tronçons longitudinaux et transversaux des alvéoles 8.The elements constituting the wall are secured by a binder such as mortar or any other equivalent material filling the conduits 9 and the longitudinal and transverse sections of the cells 8.

En fait, les conduits 9 et les tronçons transversaux 8a qui se prolongent mutuellement forment des canaux verticaux s'étendant depuis la rangée la plus basse à la rangée la plus haute et sont remplis de liant.In fact, the conduits 9 and the transverse sections 8a which extend mutually form vertical channels extending from the lowest row to the highest row and are filled with binder.

On notera ici que le liant remplissant les conduits 9 et les tronçons transversaux 8a des alvéoles assure la rigidité du mur alors que le liant remplissant le tronçon longitudinal des alvéoles rend le mur étanche vis-à-vis de l'eau de pluie, des courants d'air, du bruit et du feu, ce qui rend inutile l'application d'un enduit extérieur sur le mur et permet par conséquent une réduction notable du prix de revient de ce dernier.It will be noted here that the binder filling the conduits 9 and the transverse sections 8a of the cells ensures the rigidity of the wall while the binder filling the longitudinal section of the cells makes the wall watertight with respect to rainwater, currents air, noise and fire, which makes it unnecessary to apply an exterior coating to the wall and therefore allows a significant reduction in the cost price of the latter.

La réalisation d'un mur tel que celui représenté partiellement sur la figure 4 est particulièrement facile.The realization of a wall such as that shown partially in Figure 4 is particularly easy.

Il suffit en effet d'empiler à sec les éléments A de façon à former un certain nombre de rangées superposées, en veillant toutefois à ce que les conduits 9 ménagés entre les éléments A d'une même rangée soient chacun dans le prolongement de l'un des tronçons transversaux 8a des alvéoles de la rangée inférieure, de couler du mortier ou tout autre liant équivalent dans les canaux verticaux formés par les conduits 9 et les tronçons transversaux 8a qui se font suite, et de recommencer les deux opérations ci-dessus autant de fois que cela est nécessaire pour donner au mur la hauteur désirée.It suffices in fact to stack the elements A dry so as to form a certain number of superimposed rows, taking care however that the conduits 9 formed between the elements A of the same row are each in the extension of the one of the transverse sections 8a of the cells of the lower row, to pour mortar or any other equivalent binder in the vertical channels formed by the conduits 9 and the transverse sections 8a which follow one another, and to repeat the two above operations as much as often as necessary to give the wall the desired height.

Si on le souhaitait, on pourrait bien entendu ne couler le mortier qu'après avoir empilé la totalité des éléments A nécessaires à la réalisation du mur.If desired, one could of course only pour the mortar after having stacked all the elements A necessary for the realization of the wall.

L'élément préfabriqué B que l'on peut voir sur la figure 5 présente de grandes similitudes avec l'élément préfabriqué A représenté sur la figure 1. Il s'en distingue toutefois en ce qu'il comporte une paroi intermédiaire 11 dans chacun des tronçons verticaux 8a des alvéoles 8 et une protubérance d'extrémité 12 faisant saillie sur le fond de chacun de ses renfoncements 2.The prefabricated element B which can be seen in FIG. 5 has great similarities with the prefabricated element A represented in FIG. 1. It is distinguished from it, however, in that it comprises an intermediate wall 11 in each of the vertical sections 8a of the cells 8 and an end protrusion 12 projecting from the bottom of each of its recesses 2.

Les parois intermédiaires 11 s'étendent entre les faces supérieure 3 et inférieure 4 de l'élément préfabriqué B, parallèlement aux faces longitudinales 5 et 6 de ce dernier. Elles sont dans le prolongement l'une de l'autre et divisent chacun des tronçons transversaux 8a des alvéoles 8 en deux conduits 13 et 14, les conduits 13 étant adjacents à la face longitudinale 5.The intermediate walls 11 extend between the upper 3 and lower 4 faces of the prefabricated element B, parallel to the longitudinal faces 5 and 6 of the latter. They are in line with one another and each divide the transverse sections 8a of the cells 8 into two conduits 13 and 14, the conduits 13 being adjacent to the longitudinal face 5.

Les protubérances 12 sont également parallèles aux faces longitudinales 5 et 6 de l'élément préfabriqué B. Elles ont une hauteur égale à la profondeur du renfoncement 2 dans lequel elles sont situées et s'étendent dans le prolongement des parois intermédiaires 11.The protrusions 12 are also parallel to the longitudinal faces 5 and 6 of the prefabricated element B. They have a height equal to the depth of the recess 2 in which they are located and extend in the extension of the intermediate walls 11.

Les figure 6 représente une partie d'un mur réalisé à partir d'éléments préfabriqués B empilés à sec de la même manière que les éléments A de la figure 4.FIG. 6 represents a part of a wall produced from prefabricated elements B dry stacked in the same manner as elements A of FIG. 4.

Dans ce mur, les protubérances d'extrémité 12 des éléments préfabriqués se faisant suite dans une même rangée sont en contact et divisent les conduits 9 délimités par deux renfoncements adjacents 2 en deux conduits verticaux 15 et 16.In this wall, the end protrusions 12 of the prefabricated elements which follow in the same row are in contact and divide the conduits 9 delimited by two adjacent recesses 2 into two vertical conduits 15 and 16.

Les conduits 15, qui sont situés du côté des faces longitudinales 5 des éléments préfabriqués, ont la même section que celle des conduits 13 formés par les parois intermédiaires 11 et forment avec certains de ces conduits 13 une série de canaux verticaux s'étendant sur toute la hauteur du mur.The conduits 15, which are located on the side of the longitudinal faces 5 of the prefabricated elements, have the same section as that of the conduits 13 formed by the intermediate walls 11 and form with some of these conduits 13 a series of vertical channels extending over all the height of the wall.

Quant aux conduits 16, qui sont situés du côté des faces longitudinales 6 des éléments préfabriqués, ils ont la même section que celle des conduits 14 (qui communiquent avec les tronçons longitudinaux des alvéoles 8) et forment avec certain de ces conduits, une autre série de canaux verticaux s'étendant sur toute la hauteur du mur.As for the conduits 16, which are located on the side of the longitudinal faces 6 of the prefabricated elements, they have the same section as that of the conduits 14 (which communicate with the longitudinal sections of the cells 8) and form, with certain of these conduits, another series. vertical channels extending over the entire height of the wall.

Le liant utilisé pour solidariser entre eux les éléments préfabriqués B a été coulé dans les conduits 14 et 16 ainsi que dans les tronçons longitudinaux des alvéoles 8. En revanche, il ne l'a pas été dans les conduits 13 et 15, ni dans les cavités 7, ce qui permet de l'utiliser en une quantité inférieure à celle du liant solidarisant les éléments préfabriqués A et d'abaisser ainsi le prix de revient du mur.The binder used to secure the prefabricated elements B to each other was poured into the conduits 14 and 16 as well as into the longitudinal sections of the cells 8. On the other hand, it was not poured into the conduits 13 and 15, nor in the cavities 7, which makes it possible to use it in a quantity less than that of the binder fastening the prefabricated elements A and thus to lower the cost price of the wall.

On notera par ailleurs que lorsque les faces longitudinales 5 des éléments B constituent la face extérieure du mur et ne sont pas enduites, les conduits 13 et 15 permettent avec les cavités 7 (dont le fond a été supprimé) d'évacuer vers le bas du mur, l'eau de pluie qui se propagerait jusqu'à eux et protègent donc mieux l'intérieur de la construction contre l'humidité.It will also be noted that when the longitudinal faces 5 of the elements B constitute the external face of the wall and are not coated, the conduits 13 and 15 allow, with the cavities 7 (the bottom of which has been removed) to evacuate downwards from the wall, rainwater that would spread to them and therefore better protect the interior of the building against moisture.

L'extrémité inférieure des canaux formés par les conduits 13 et 15, ainsi que par les cavités 7, doit communiquer avec l'extérieur pour évacuer l'eau recueillie. La réalisation de cette communication constitue une opération classique pour un maçon et l'on s'abstiendra donc de la décrire ici.The lower end of the channels formed by the conduits 13 and 15, as well as by the cavities 7, must communicate with the outside to evacuate the water collected. The realization of this communication constitutes an operation classic for a mason and we will therefore refrain from describing it here.

Pour être complet, on précisera que les éléments préfabriqués B sont pourvus dans leur face supérieure 3 d'un renfoncement 17 entre les tronçons longitudinaux des alvéoles 8 et d'un renfoncement 18 entre chacun desdits tronçons longitudinaux et le renfoncement 2 adjacent.To be complete, it will be specified that the prefabricated elements B are provided in their upper face 3 with a recess 17 between the longitudinal sections of the cells 8 and with a recess 18 between each of said longitudinal sections and the adjacent recess 2.

Grâce à ces renfoncements 17 et 18, la répartition du liant entre les différents conduits destinés à le recevoir peut être assurée plus facilement, ce qui garantit une parfaite étanchéité entre les rangées horizontales superposées d'éléments préfabriqués.Thanks to these recesses 17 and 18, the distribution of the binder between the various conduits intended to receive it can be ensured more easily, which guarantees a perfect seal between the horizontal rows superimposed of prefabricated elements.
