Description

Le domaine de la présente invention est celui des blocs de coffrage isolants, utilisés pour l'élaboration de paroi par coulée de matière telle que du béton. Elle a pour objet un tel bloc de coffrage.The field of the present invention is that of insulating shuttering blocks used for the production of walls by casting material such as concrete. It relates to such a formwork block.

Un bloc de coffrage est classiquement constitué par deux éléments isolants distants l'un de l'autre, reliés par une structure préférentiellement métallique. Pour des raisons thermiques et phoniques, il est avantageux d'utiliser de la mousse de polystyrène. Ce matériaux est retenu dans la suite de la description, mais uniquement à but illustratif.A formwork block is conventionally constituted by two insulating elements distant from each other, connected by a preferentially metallic structure. For thermal and acoustic reasons, it is advantageous to use polystyrene foam. This material is retained in the following description, but only for illustrative purposes.

On connaît par FR-A-2 132 597 , un procédé de fabrication d'un mur par coffrage, en utilisant un coffrage perdu sous la forme de blocs de construction creux assemblés, et dans lesquels du béton est coulé. Néanmoins, un tel coffrage nécessite encore la réalisation d'une isolation externe.We know by FR-A-2,132,597 , a method of manufacturing a wall by shuttering, using a lost formwork in the form of assembled hollow building blocks, and in which concrete is poured. Nevertheless, such a formwork still requires the realization of an external insulation.

Par ailleurs, FR-A-2 556 387 décrit un élément de construction destiné à former un coffrage isolant pour réaliser un mur en y coulant du béton. Ce bloc présente un ensemble d'orifices régulièrement espacés pour le passage de tiges de positionnement des blocs les uns par rapport aux autres. Les chants verticaux présentent, en outre, un moyen d'assemblage avec un autre bloc adjacent.Otherwise, FR-A-2,556,387 discloses a structural member for forming an insulating form for making a wall by pouring concrete therein. This block has a set of orifices regularly spaced for the passage of positioning rods of the blocks relative to each other. The vertical edges have, in addition, an assembly means with another adjacent block.

Enfin, FR-A-2 531 988 divulgue un coffrage isolant, avec différents modules constitutifs, à savoir un module de taille normale, un demi-module pour tenir compte de la quinconce entre deux rangées, un module d'extrémité, et un demi-module d'extrémité.Finally, FR-A-2,531,988 discloses an insulating formwork, with different constituent modules, namely a normal size module, a half-module to take into account the stagger between two rows, an end module, and a half-end module.

Toutefois, un des problèmes posés par les blocs de coffrage est que les deux éléments qui composent un bloc de coffrage doivent avoir une tenue mécanique suffisante pour résister à la charge et la pression créées par la matière coulée. Cela se caractérise donc par l'utilisation d'une matière isolante particulièrement chère. En outre, afin d'augmenter encore l'isolation pour une construction dans laquelle un tel bloc est utilisé, il est souhaitable d'augmenter l'épaisseur de l'élément qui se trouve du côté extérieur. Cela se traduit donc par une forte élévation du coût matière, puisque l'élément extérieur est réalisé d'un seul tenant, donc dans une seule et même matière. Un autre problème causé par l'augmentation de matière dissymétrique est l'apparition de déformations thermiques résiduelles. Le temps de refroidissement est, lui aussi, largement augmenté.However, one of the problems posed by the formwork blocks is that the two elements that make up a formwork block must have sufficient mechanical strength to withstand the load and the pressure created by the cast material. This is therefore characterized by the use of a particularly expensive insulating material. In addition, in order to further increase the insulation for a construction in which such a block is used, it is desirable to increase the thickness of the element which is on the outside. This therefore results in a high increase in material cost, since the outer element is made in one piece, so in one and the same material. Another problem caused by the increase of material asymmetrical is the appearance of residual thermal deformations. The cooling time is also greatly increased.

Dans le but d'obtenir une construction résistante à l'humidité, US-A-1 441 362 décrit un bloc de construction creux, constitué de deux pièces assemblées l'une à l'autre, de formes telles qu'en les assemblant, elles définissent à la fois un conduit horizontal et un conduit vertical pour un passage d'air. Cette divulgation n'est cependant pas adaptée aux coffrages isolants, qui doivent garantir l'écoulement et le remplissage correct du béton, ainsi que résister à la pression créée par la masse de matière coulée.In order to obtain a moisture resistant construction, US-A-1,441,362 discloses a hollow building block, consisting of two parts assembled to one another, shapes such as assembling them, they define both a horizontal duct and a vertical duct for an air passage. This disclosure, however, is not suitable for insulating forms, which must ensure the flow and correct filling of the concrete, as well as resist the pressure created by the mass of cast material.

On connaît aussi du document DE 200 03 380 un bloc de construction creux contre lequel un élément isolant peut être glissé.Document is also known DE 200 03 380 a hollow building block against which an insulating element can be slid.

Ce document divulgue toutes les caractéristiques du préambule de la revendication 1.This document discloses all the features of the preamble of claim 1.

La présente invention a pour but de pallier ces inconvénients en proposant un bloc de coffrage ayant des capacités isolantes accrues, un coût de fabrication faible, et une résistance mécanique suffisante pour supporter la matière coulée.The present invention aims to overcome these disadvantages by providing a formwork block having increased insulating capacity, a low manufacturing cost, and sufficient strength to support the cast material.

A cet effet, l'invention a pour objet un bloc de coffrage isolant, comprenant les caractéristiques du préambule de la revendication 1.For this purpose, the subject of the invention is an insulating shuttering block comprising the features of the preamble of claim 1.

Ce bloc de coffrage est caractérisé par la partie caractérisante de la revendication 1.This formwork block is characterized by the characterizing part of claim 1.

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 :

  • la figure 1 est une vue frontale d'un bloc de coffrage selon l'invention, sans le coulisseau ;
  • la figure 2 est une vue de côté correspondant à la figure 1 ;
  • la figure 3 est une vue frontale de la face supérieure du coulisseau ;
  • la figure 4 est la vue opposée à la vue de la figure 3, et représente l'autre face frontale du coulisseau ;
  • la figure 5 est une vue de côté du coulisseau ;
  • la figure 6 est une vue frontale du bloc de coffrage selon l'invention, et la figure 7 est une vue de côté correspondant à la figure 6.
The invention will be better understood, thanks to the following description, which refers to a preferred embodiment, given by way of non-limiting example, and explained with reference to the attached schematic drawings, in which:
  • the figure 1 is a front view of a formwork block according to the invention, without the slide;
  • the figure 2 is a side view corresponding to the figure 1 ;
  • the figure 3 is a front view of the upper face of the slider;
  • the figure 4 is the opposite view to the view of the figure 3 and represents the other end face of the slider;
  • the figure 5 is a side view of the slider;
  • the figure 6 is a front view of the formwork block according to the invention, and the figure 7 is a side view corresponding to the figure 6 .

L'invention a pour objet un bloc de coffrage isolant 1, comprenant une paroi intérieure 2 ainsi qu'une paroi extérieure 20, reliée à la paroi intérieure 2 par des moyens de liaison et/ou de renfort 17, ladite paroi extérieure 20 étant plus épaisse que la paroi intérieure 2. Selon l'invention, la paroi extérieure 20 se compose d'un premier élément 3, fixé à la paroi intérieure 2, et d'un deuxième élément 7 en matière isolante, rapporté sur le premier élément 3.The invention relates to an insulating shuttering block 1, comprising an inner wall 2 and an outer wall 20, connected to the inner wall 2 by connecting and / or reinforcing means 17, said outer wall 20 being more 2. In accordance with the invention, the outer wall 20 is composed of a first element 3 fixed to the inner wall 2 and a second element 7 of insulating material attached to the first element 3.

De préférence, le deuxième élément 7 en matière isolante est constitué en une mousse. Le premier élément 3 présente une face supérieure 4, une face inférieure 5, et une face extérieure 6, ledit premier élément 3, le deuxième élément 7, ainsi que la paroi intérieure 2 étant réalisés avec de la matière spécialement isolante au moins thermiquement et acoustiquement, préférentiellement de la mousse telle que du polystyrène expansé.Preferably, the second element 7 of insulating material is made of a foam. The first element 3 has an upper face 4, a lower face 5, and an outer face 6, said first element 3, the second element 7, and the inner wall 2 being made of at least thermally and acoustically insulating material. , preferably foam such as expanded polystyrene.

Afin de permettre le coffrage, le premier élément 3 est relié à la paroi intérieure 2 par des moyens de liaison et/ou de renfort 17. Un espace 21 est donc créé, entre le premier élément 3 et la paroi intérieure 2, dans lequel le béton, ou une autre matière de construction, peut être coulé. Les moyens de liaison et/ou de renfort 17 maintiennent le premier élément 3 et la paroi intérieure 2 l'un à l'autre, ce qui permet de stabiliser l'ensemble, entre autres lors de la coulée du béton. Le premier élément 3 est réalisé en matière isolante, mais néanmoins suffisamment dense pour supporter le poids et la pression de la matière coulée. Il peut s'agir, dans un mode de réalisation préféré, de polystyrène ayant une densité de 30 kg/m3. Dans le mode de réalisation illustré, l'épaisseur du premier élément 3 est plus importante que celle de la paroi intérieure 2, pour garantir une bonne qualité d'isolation.In order to allow the formwork, the first element 3 is connected to the inner wall 2 by connecting and / or reinforcing means 17. A space 21 is thus created between the first element 3 and the inner wall 2, in which the concrete, or other construction material, can be cast. The connecting means and / or reinforcement 17 maintain the first element 3 and the inner wall 2 to each other, which stabilizes the assembly, among others during the casting of concrete. The first element 3 is made of insulating material, but nevertheless dense enough to support the weight and pressure of the cast material. It may be, in a preferred embodiment, polystyrene having a density of 30 kg / m 3 . In the illustrated embodiment, the thickness of the first element 3 is greater than that of the inner wall 2, to ensure a good quality of insulation.

Le deuxième élément prend la forme d'un coulisseau 7 rapporté sur le premier élément 3 au moyen d'une glissière et ayant une forme en L, le premier élément 3 présentant une forme complémentaire à ce L, de sorte que ledit coulisseau 7 peut glisser contre le premier élément 3 par une première branche verticale 8 du L jusqu'à être bloqué par une deuxième branche horizontale 9 du L. La première branche verticale 8 du L par laquelle le coulisseau 7 glisse le long du premier élément 3, lors de son montage sur ce dernier, correspond donc approximativement à la glissière. La deuxième branche 9 forme une butée d'appui sous le premier élément 3.The second element takes the form of a slider 7 attached to the first element 3 by means of a slideway and having an L shape, the first element 3 having a shape complementary to this L, so that said slider 7 can slide against the first element 3 by a first vertical leg 8 of the L to be blocked by a second horizontal leg 9 of L. The first vertical leg 8 of the L by which the slider 7 slides along the first element 3, during its mounting on the latter, therefore corresponds approximately to the slide. The second branch 9 forms a bearing abutment under the first element 3.

Dans le mode de réalisation décrit, la glissière est linéaire et parallèle à la façade formée par l'empilement de blocs de coffrage isolants 1. Cette glissière est réalisée par coopération de forme entre le premier élément 3 et le coulisseau 7.In the embodiment described, the slideway is linear and parallel to the facade formed by the stack of insulating shuttering blocks 1. This slideway is formed by shape cooperation between the first element 3 and the slide 7.

Le coulisseau 7 est préférentiellement réalisé en mousse de polystyrène, et, comme la tenue mécanique est apportée par le premier élément 3, la densité de la matière constitutive du coulisseau 7 peut être plus faible, réduisant ainsi le coût du bloc de coffrage isolant 1. Ce coulisseau 7 est donc avantageusement réalisé dans une matière différente, préférentiellement dans une matière moins résistante mécaniquement que la matière utilisée pour le premier élément 3. Le coulisseau 7 est monté sur le premier élément 3 par un mouvement de translation, guidé par la glissière. Cette glissière est préférentiellement verticale dans la position d'utilisation du bloc de coffrage 1. Le coulissement se fait le long de la face extérieure 4 du premier élément 3, et le coulisseau 7, ainsi que le bloc 4 présentent donc chacun des formes aptes à coopérer à la manière d'une glissière. Dans une variante de réalisation de l'invention non représentée aux dessins annexés, la glissière est horizontale, une fois les blocs de coffrage isolants 1 installés.The slider 7 is preferably made of polystyrene foam, and, as the mechanical strength is provided by the first element 3, the density of the constituent material of the slider 7 can be lower, thus reducing the cost of the insulating shuttering block 1. This slider 7 is therefore advantageously made of a different material, preferably in a less mechanically resistant material than the material used for the first element 3. The slider 7 is mounted on the first element 3 by a translational movement, guided by the slide. This slide is preferably vertical in the use position of the shuttering block 1. The sliding is along the outer face 4 of the first element 3, and the slider 7, and the block 4 each have shapes suitable for cooperate in the manner of a slide. In an alternative embodiment of the invention not shown in the accompanying drawings, the slide is horizontal, once the insulating shuttering blocks 1 installed.

La glissière permet le mouvement dans un plan parallèle à la face extérieure 4 du premier élément 3, ce qui correspond au plan de la façade construite par l'empilement de blocs de coffrage isolants 1. En outre, la glissière permet aussi de retenir le coulisseau 7 perpendiculairement au plan, dans lequel elle permet le mouvement. Le coulisseau 7 est donc monté contre le premier élément 3 dans un mouvement de translation linéaire parallèle à la paroi créée.The slide allows movement in a plane parallel to the outer face 4 of the first element 3, which corresponds to the plane of the facade constructed by the stack of insulating shuttering blocks 1. In addition, the slide also allows to retain the slide 7 perpendicular to the plane, in which it allows movement. The slider 7 is thus mounted against the first element 3 in a linear translational movement parallel to the wall created.

Selon une caractéristique avantageuse, le coulisseau 7 en forme de L est délimité, à la partie supérieure de la branche verticale du L par une face supérieure 10 et à la partie inférieure de cette branche, correspondant à la branche horizontale du L, par une face inférieure 11, ces deux faces étant reliées par une face extérieure verticale 12, la face inférieure 11 du coulisseau 7 présentant une longueur supérieure à celle de la face supérieure 10 dudit coulisseau 7, la face intérieure 14 de ladite aile verticale du L, perpendiculaire à la face supérieure 10 du coulisseau 7 et parallèle à la face extérieure 12 s'étendant jusqu'à une paroi horizontale 11' parallèle à la face inférieure 11 de la branche horizontale du L et déterminant l'épaisseur de cette dernière.According to an advantageous characteristic, the slider 7 in the shape of an L is delimited, at the upper part of the vertical branch of the L, by an upper face 10 and at the lower part of this branch, corresponding to the horizontal branch of the L, by a face lower 11, these two faces being connected by a vertical outer face 12, the lower face 11 of the slider 7 having a length greater than that of the upper face 10 of said slider 7, the inner face 14 of said vertical flange of the L, perpendicular to the upper face 10 of the slider 7 and parallel to the outer face 12 extending to a horizontal wall 11 'parallel to the lower face 11 of the horizontal arm of the L and determining the thickness of the latter.

Il en résulte que le contact entre le coulisseau 7 et le premier élément 3 se fait par une mise en contact de la face extérieure 6 du premier élément 3 avec la face intérieure 14 de l'aile verticale du L formant le coulisseau 7. La glissière est donc aménagée, d'une part, au niveau de la face intérieure 14 du coulisseau 7 et, d'autre part, sur la face extérieure 6 du premier élément 3. L'aile horizontale du coulisseau 7 en forme de L s'étend dans un renfoncement 18 du premier élément 3, qui a une forme complémentaire correspondante. Le premier élément 3 peut donc accueillir la partie correspondante de l'aile horizontale du coulisseau 7, c'est-à-dire la partie 19 de ce dernier.As a result, the contact between the slider 7 and the first element 3 is made by contacting the outer face 6 of the first element 3 with the inner face 14 of the vertical wing of the L forming the slider 7. The slider is therefore arranged, on the one hand, at the inner face 14 of the slider 7 and, on the other hand, on the outer face 6 of the first element 3. The horizontal flange of the L-shaped slider 7 extends in a recess 18 of the first element 3, which has a corresponding complementary shape. The first element 3 can therefore accommodate the corresponding portion of the horizontal wing of the slider 7, that is to say the part 19 of the latter.

Ainsi, après installation de blocs de coffrage isolants 1 les uns sur les autres, un coulisseau 7 en forme de L peut être en contact, au moins par une partie de sa face inférieure 11, avec la face supérieure 4 d'un autre premier élément 3 situé au-delà de la face inférieure 11 du coulisseau 7. En effet, d'une part, la face inférieure 5 du premier élément 3 et la face inférieure 11 du coulisseau 7 mises côté à côte, et, d'autre part, la face supérieure 4 du premier élément 3 et la face supérieure 10 du coulisseau 7 mises côte à côte, représentent la même surface. La face supérieure 4 du premier élément 3 est plus grande que sa face inférieure 5, ce qui permet à la face supérieure 4 du premier élément 3 et la face inférieure 11 du coulisseau 7 d'être en contact par chevauchement.Thus, after installation of insulating shuttering blocks 1 on each other, an L-shaped slider 7 may be in contact, at least by a part of its lower face 11, with the upper face 4 of another first element. 3 located beyond the lower face 11 of the slide 7. In fact, on the one hand, the lower face 5 of the first element 3 and the lower face 11 of the slide 7 placed side by side, and, on the other hand, the upper face 4 of the first element 3 and the upper face 10 of the slide 7 placed side by side, represent the same surface. The upper face 4 of the first element 3 is larger than its lower face 5, which allows the upper face 4 of the first element 3 and the lower face 11 of the slider 7 to be in overlapping contact.

Dans une construction où les blocs de coffrage isolants 1 sont empilés les uns sur les autres, il n'est donc jamais nécessaire de prévoir un support pour retenir le coulisseau 7 de la rangée la plus basse.In a construction where the insulating shuttering blocks 1 are stacked on each other, it is therefore never necessary to provide a support to retain the slider 7 of the lowest row.

Avantageusement, la glissière se présente sous la forme d'une liaison en queue d'aronde 13 entre une face intérieure 14 du coulisseau 7 et la face extérieure 6 du premier élément 3, dans le plan de laquelle ou desquelles la queue d'aronde 13 permet un mouvement de translation. Ainsi, la glissière permet, entre autres, à la fois de guider le coulisseau 7 lors de son montage sur le premier élément 3 et d'empêcher l'arrachage du coulisseau perpendiculairement à sa face intérieure. Il est donc possible de découper le bloc de coffrage isolant 1, et, plus particulièrement, le premier élément 3, sans pour autant que le coulisseau 7 ne se sépare du premier élément 3.Advantageously, the slide is in the form of a dovetail connection 13 between an inner face 14 of the slider 7 and the outer face 6 of the first element 3, in the plane of which or the dovetail 13 allows a translation movement. Thus, the slide allows, among other things, both to guide the slide 7 during its mounting on the first element 3 and to prevent tearing of the slide perpendicularly to its inner face. It is therefore possible to cut the insulating shuttering block 1, and more particularly the first element 3, without the slider 7 being separated from the first element 3.

Selon une autre caractéristique de l'invention, la hauteur totale du premier élément 3, c'est-à-dire la distance séparant la face inférieure 5 et la face supérieure 4 du premier élément 3, est égale à la hauteur du coulisseau 7, et correspondant donc à la longueur de la branche verticale du L, c'est-à-dire à la distance séparant la face inférieure 11 et la face supérieure 10 du coulisseau 7. Ainsi, lorsque des blocs de coffrage isolants 1 sont empilés les uns sur les autres, la face supérieure 10 du coulisseau 7 et la face supérieure 4 du premier élément 3 sont dans le même plan, formant ainsi un seul plan d'appui pour un autre premier élément 3 ou un autre bloc de coffrage isolant 1.According to another characteristic of the invention, the total height of the first element 3, that is to say the distance separating the lower face 5 and the upper face 4 of the first element 3, is equal to the height of the 7, and thus corresponding to the length of the vertical leg of the L, that is to say, the distance between the lower face 11 and the upper face of the slider 7. Thus, when insulating formwork blocks 1 are stacked on top of each other, the upper face 10 of the slider 7 and the upper face 4 of the first element 3 are in the same plane, thus forming a single support plane for another first element 3 or another insulating shuttering block 1.

Enfin, selon une caractéristique particulièrement avantageuse de l'invention, la face supérieure 10 du coulisseau 7 et la face supérieure 4 du premier élément 3 présentent un premier motif géométrique 15, apte à coopérer avec un deuxième motif géométrique 16, aménagé sur la face inférieure 11 du coulisseau 7 et la face inférieure 5 du premier élément 3. Dans le mode de réalisation, ce premier motif géométrique 15 est un ensemble de bourrelets sous la forme de couronnes, régulièrement espacés, le deuxième motif géométrique 16 étant sous la forme d'un ensemble correspondant de creux. Ainsi, un bloc de coffrage isolant 1 peut être correctement positionné par rapport à un bloc de coffrage isolant 1 analogue, avec qui il est en contact.Finally, according to a particularly advantageous characteristic of the invention, the upper face 10 of the slider 7 and the upper face 4 of the first element 3 have a first geometric pattern 15, able to cooperate with a second geometric pattern 16, arranged on the lower face. 11 of the slider 7 and the lower face 5 of the first element 3. In the embodiment, this first geometric pattern 15 is a set of beads in the form of rings, regularly spaced, the second geometric pattern 16 being in the form of a corresponding set of troughs. Thus, an insulating shuttering block 1 can be correctly positioned relative to an insulating shuttering block 1 analog, with which it is in contact.

Dans le mode de réalisation illustré, le premier motif géométrique 15 et le deuxième motif géométrique 16 sont disposés sous la forme de rangées parallèles. La face supérieure 4 du premier élément 3 a une largeur correspondante à deux rangées, ainsi que la face inférieure 11 du coulisseau 7. La face inférieure 5 du premier élément a une largeur correspondant à une rangée, ainsi que la face supérieure 10 du coulisseau 7.In the illustrated embodiment, the first geometric pattern 15 and the second geometric pattern 16 are arranged in parallel rows. The upper face 4 of the first element 3 has a width corresponding to two rows, and the lower face 11 of the slider 7. The lower face 5 of the first element has a width corresponding to one row, as well as the upper face 10 of the slider 7 .

La glissière est telle que, quand le coulisseau 7 arrive en butée avec cette glissière, la face inférieure 11 du coulisseau 7 et la face inférieure 5 du premier élément 3 sont situées dans un même plan. Ainsi, une fois le coulisseau 7 glissé contre un premier élément 3 et arrivé en butée, et dans une situation où les blocs de coffrage isolants 1 sont empilés, le coulisseau peut être entièrement bloqué dans le mouvement permis par la glissière dans un sens, par la partie 19 formant la butée de la glissière lorsqu'elle se trouve dans le renfoncement 18, et, dans l'autre sens, par la face supérieure 4 d'un autre premier élément 3 et/ou la face supérieure 10 d'un autre coulisseau 7.The slide is such that when the slider 7 comes into abutment with this slide, the lower face 11 of the slider 7 and the lower face 5 of the first element 3 are located in the same plane. Thus, once the slider 7 has slid against a first element 3 and come to a stop, and in a situation where the insulating shuttering blocks 1 are stacked, the slider can be completely locked in the movement allowed by the slider in one direction, for example. the portion 19 forming the abutment of the slide when it is in the recess 18, and in the other direction, by the upper face 4 of another first element 3 and / or the upper face 10 of another slide 7.

Grâce à l'invention, il est donc possible, dans la construction d'un coffrage pour une paroi verticale, de faire reposer un bloc de coffrage isolant 1 sur un simple premier élément 3, et ce sans utiliser de réglette support pour la surépaisseur que forme le coulisseau 7, mais aussi de faire reposer des blocs de coffrage isolants 1 l'un sur l'autre, sans prévoir de support spécifique pour le coulisseau 7, puisque celui-ci est calé entre le premier élément 3 du bloc de coffrage isolant 1, dont il fait partie, et un autre bloc de coffrage isolant 1. En outre, lorsque le bloc de coffrage isolant 1 est posé sur une surface plane, le coulisseau 7 et le premier élément 3, forment à leur tour une surface d'appui plane pour accueillir de façon stable et plane un autre bloc de coffrage isolant 1.Thanks to the invention, it is therefore possible, in the construction of a formwork for a vertical wall, to rest a formwork block insulation 1 on a simple first element 3, and without using a support strip for the extra thickness that forms the slider 7, but also to make insulating form blocks 1 on top of each other, without providing specific support for the slider 7, since it is wedged between the first element 3 of the insulating shuttering block 1, of which it forms part, and another insulating shuttering block 1. In addition, when the insulating shuttering block 1 is placed on a planar surface, the slider 7 and the first element 3, in turn form a flat bearing surface for stably and flatly receiving another insulating shuttering block 1.

Ainsi, après mise en place, d'une part, la face inférieure 11 du coulisseau 7 se trouve au niveau de la face inférieure 5 du premier élément 3, et, d'autre part, la face supérieure 10 du coulisseau 7 se trouve au niveau de la face supérieure du premier élément 3. Toutefois, la face supérieure 4 du premier élément 3 peut être au-dessus ou au-dessous de sa face inférieure 5. Dans le premier cas, l'installation du coulisseau 7 sur le premier élément 3 correspond à un mouvement réalisé de bas en haut. Dans le deuxième cas, il correspond à un mouvement réalisé de haut en bas.Thus, after placement, on the one hand, the lower face 11 of the slider 7 is at the lower face 5 of the first element 3, and, on the other hand, the upper face 10 of the slider 7 is at the level of the upper face of the first element 3. However, the upper face 4 of the first element 3 may be above or below its lower face 5. In the first case, the installation of the slider 7 on the first element 3 corresponds to a movement made from the bottom up. In the second case, it corresponds to a movement made from top to bottom.
