Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne le domaine des éléments de construction préfabriqués, notamment pour la réalisation d'ouvrages tels que des piscines ou des éléments de piscine.The present invention relates to the field of prefabricated construction elements, in particular for the production of works such as swimming pools or swimming pool elements.

Plus particulièrement, l'invention concerne un bloc modulaire à bancher et trouve notamment son application dans la réalisation de marches d'escalier d'angle de piscines.More particularly, the invention relates to a modular block for shuttering and finds its application in particular in the production of corner steps for swimming pools.

ARRIERE PLAN TECHNOLOGIQUE DE L'INVENTIONTECHNOLOGICAL BACKGROUND OF THE INVENTION

De manière habituelle, de tels escaliers consistent soit en une construction monobloc rapportée et fixée à une paroi ou dans l'angle que forment deux murs du bassin, soit en une structure maçonnée, réalisée comme la construction d'un mur, par empilement de briques, ou par coulage de béton dans un coffrage.Usually, such stairs consist either of a single-piece construction attached and fixed to a wall or in the angle formed by two walls of the basin, or of a masonry structure, produced like the construction of a wall, by stacking bricks. , or by pouring concrete into a formwork.

Les escaliers monoblocs sont très coûteux, car ils nécessitent des moules de grandes dimensions, ils sont également très encombrants aussi bien en ce qui concerne leur stockage que leur transport. De plus le nombre de modèles proposés est limité, en sorte qu'ils ne permettent pas des réalisations originales.One-piece stairs are very expensive, because they require large molds, they are also very bulky both as regards their storage and their transport. In addition, the number of models offered is limited, so that they do not allow original designs.

Les escaliers maçonnés permettent plus d'originalités, dans les limites toutefois des structures utilisées et des capacités de l'installateur. Ils présentent également des inconvénients, notamment d'une mise en œuvre longue, plus particulièrement lorsqu'ils sont faits en béton coulé, notamment pour mettre en place le coffrage. Les moyens de coffrage classique en bois doivent être retirés après construction.Masonry staircases allow for more originalities, however within the limits of the structures used and the capabilities of the installer. They also have drawbacks, in particular of a long implementation, more particularly when they are made of poured concrete, in particular for placing the formwork. Classic wooden formwork means must be removed after construction.

Une autre technique de coffrage également classiquement utilisée dans le domaine de la construction des piscines, et notamment la construction d'escalier de piscines, consiste à utiliser des blocs de banchage qui demeurent dans la construction après que le béton a été coulé à l'intérieur de ceux-ci et s'y est solidifié. Les blocs de banchage actuellement utilisés sont de forme rectangulaire ou cubique et nécessitent des travaux de découpe et d'ajustement dans le cas particulier d'escalier d'angle. Ces travaux de découpe et d'ajustement peuvent être difficiles, longs et donc couteux. Par ailleurs, les dimensions exactes d'un escalier d'angle peuvent varier selon les ajustements réalisés pour compenser l'imprécision des découpes. Il est donc nécessaire d'adapter également les dimensions exactes de l'enveloppe souple d'étanchéité (« liner ») à chaque construction, ce qui est également couteux et génère des délais de livraison plus longs. De plus, l'imprécision des découpes et/ou des prises de mesure peut être à l'origine de défauts lors de l'installation du « liner », pouvant notamment générer des problèmes d'étanchéité au moment de la mise en fonctionnement de la piscine.Another formwork technique also conventionally used in the field of swimming pool construction, and in particular the construction of swimming pool stairs, consists in using benches which remain in the construction after the concrete has been poured inside. of these and solidified in them. The benches currently used are rectangular or cubic in shape and require cutting and adjustment work in the particular case of corner stairs. These cutting and adjustment jobs can be difficult, long and therefore expensive. In addition, the exact dimensions of a corner staircase may vary depending on the adjustments made to compensate for the imprecision of the cutouts. It is therefore necessary to also adapt the exact dimensions of the flexible sealing envelope (“liner”) to each construction, which is also expensive and generates longer delivery times. In addition, the imprecision of the cutouts and / or of the measurements can be the source of faults during the installation of the "liner", which can in particular generate sealing problems when the unit is put into operation. swimming pool.

On connaît aussi, dans le domaine général de la construction, les structures à bancher décrites dans les documents FR 2747140 A1 , US5247773 et US4550543 .Also known, in the general field of construction, the structures to be shuttered described in the documents FR 2747 140 A1 , US5247773 and US4550543 .

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Selon des caractéristiques avantageuses de l'invention, prises seules ou en combinaison :

  • le logement traversant est défini par au moins trois parois formant les faces latérales rectangulaires du prisme droit, deux de ces parois présentant les mêmes dimensions ;
  • le logement traversant comporte une pluralité de nervures délimitant au moins un compartiment traversant ;

Ces caractéristiques avantageuses permettent d'une part d'assurer une bonne rigidité et améliorent la tenue mécanique du bloc modulaire lors du remplissage par la matière de banchage.

  • les deux parois présentant les mêmes dimensions sont orthogonales ;
These advantageous characteristics make it possible, on the one hand, to ensure good rigidity and improve the mechanical strength of the modular block during filling with the benching material.
  • the two walls having the same dimensions are orthogonal;

Ainsi, le bloc modulaire est particulièrement adapté à la construction d'escaliers d'angle droit, qui sont les plus courants, l'angle droit au niveau du sommet des bases triangulaires du prisme droit permettant d'optimiser le nombre de blocs modulaires à assembler pour constituer les futures marches de l'escalier.Thus, the modular block is particularly suitable for the construction of right angle stairs, which are the most common, the right angle at the level of the top of the triangular bases of the right prism making it possible to optimize the number of modular blocks to be assembled. to constitute the future steps of the staircase.

Selon d'autres caractéristiques avantageuses de l'invention, prises seules ou en combinaison :

  • les moyens d'assemblage sont formés sur chacune des 2 parois latérales de même dimension ;
  • la rainure comporte une butée en son extrémité la plus étroite apte à bloquer un tenon d'un autre bloc dans une position définie d'assemblage ;
  • le tenon comporte une encoche en son extrémité la plus étroite apte à coopérer avec la butée de la rainure d'un autre bloc, pour bloquer le tenon dans une position définie d'assemblage ;
According to other advantageous characteristics of the invention, taken alone or in combination:
  • the assembly means are formed on each of the 2 side walls of the same size;

Selon d'autres caractéristiques avantageuses de l'invention :

  • les parois, les nervures et les moyens d'assemblage sont constitués de matière plastique ;
  • les moyens d'assemblage sont intégrés aux parois latérales de même dimension ;

L'invention concerne également un assemblage constitué d'une pluralité de blocs modulaires à bancher, les blocs modulaires étant juxtaposés en rangées.The invention also relates to an assembly made up of a plurality of modular blocks to be shuttered, the modular blocks being juxtaposed in rows.

Cet assemblage pourra comprendre en outre, une pluralité de rangées de blocs modulaires superposées les unes sur les autres.This assembly may further comprise a plurality of rows of modular blocks superimposed on one another.

Selon une caractéristique avantageuse, l'assemblage comportant une pluralité de blocs modulaires à bancher superposés pourra également comporter un rail glissé dans une ouverture formée par l'alignement des compartiments traversants des blocs modulaires.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Les figures 1 à 3 représentent un bloc modulaire à bancher 1 conforme à l'invention et formant un élément de coffrage perdu pour la construction d'ouvrage tel que des piscines et des escaliers, notamment des escaliers d'angle de piscine.The figures 1 to 3 represent a modular shuttering block 1 in accordance with the invention and forming a permanent shuttering element for the construction of structures such as swimming pools and stairs, in particular swimming pool corner stairs.

Par «bloc modulaire», on comprend un élément apte à être assemblé avec d'autres éléments identiques, à l'aide de moyens d'assemblage décrits plus en détail par la suite.The term “modular block” is understood to mean an element capable of being assembled with other identical elements, using assembly means described in more detail below.

Le bloc modulaire à bancher 1 se présente sous la forme d'un prisme droit dont les faces A, B en forment les bases triangulaires isocèles.The modular shuttering block 1 is in the form of a right prism, the faces A, B of which form the isosceles triangular bases.

Le bloc modulaire 1 comporte un logement traversant, avantageusement défini par au moins trois parois 3, 4, 5 formant les faces latérales rectangulaires (C, D, E) du prisme droit, qui relie la première face A et la deuxième face B et sert à la réception d'un matériau de remplissage, en particulier, du béton à couler. Le logement traversant n'a donc pas de paroi fermée au niveau des faces A, B ce qui rend possible l'écoulement du matériau de remplissage à travers le bloc modulaire.The modular block 1 comprises a through housing, advantageously defined by at least three walls 3, 4, 5 forming the rectangular side faces (C, D, E) of the right prism, which connects the first face A and the second face B and serves to receive a filling material, in particular, concrete to be poured. The through housing therefore does not have a closed wall at the level of the faces A, B, which makes it possible for the filling material to flow through the modular block.

Préférentiellement, le logement traversant comporte une pluralité de nervures 6 délimitant des compartiments de taille suffisante pour permettre un écoulement efficace du matériau de remplissage dans la structure. Par nervure, on entend une paroi interne au logement traversant dont au moins une extrémité peut prendre appui sur une des trois parois 3, 4, 5 du logement traversant.Preferably, the through housing comprises a plurality of ribs 6 delimiting compartments of sufficient size to allow efficient flow of the filling material in the structure. By rib is meant an internal wall of the through housing, at least one end of which can bear on one of the three walls 3, 4, 5 of the through housing.

Comme illustré sur les figures 1 et 2, mais à titre d'exemple seulement, les nervures 6 délimitent 9 compartiments de tailles différentes à l'intérieur du logement traversant.As shown on figures 1 and 2 , but by way of example only, the ribs 6 define 9 compartments of different sizes inside the through housing.

Ces nervures 6 et les parois 3, 4, 5 permettent de rigidifier la structure du bloc modulaire 1 et renforcent sa tenue mécanique aux pressions internes exercées par le matériau de remplissage.These ribs 6 and the walls 3, 4, 5 make it possible to stiffen the structure of the modular block 1 and reinforce its mechanical strength to the internal pressures exerted by the filling material.

Selon une variante non représentée, une partie de l'une ou des deux faces A, B pourra être fermée par une paroi, obturant ainsi une partie des compartiments du logement traversant : cette variante permet de limiter le nombre de compartiments traversants et donc la quantité de matériau de remplissage introduite dans le bloc pour le coffrage.According to a variant not shown, part of one or both sides A, B may be closed by a wall, thus closing off part of the compartments of the through housing: this variant makes it possible to limit the number of through compartments and therefore the quantity of filling material introduced into the block for the shuttering.

La hauteur h du bloc modulaire 1 constitue une dimension de la paroi latérale 5.The height h of the modular block 1 constitutes a dimension of the side wall 5.

Les bases triangulaires du prisme étant isocèles, les deux parois latérales 3, 4, appelées parois latérales principales, sont de dimensions identiques. Les deux parois latérales principales sont agencées pour former entre elle un angle déterminé. Cet angle peut être choisi pour correspondre à (ou être un diviseur d') un angle d'un bassin de piscine dans lequel un escalier doit être formé. Avantageusement, et comme cela est représenté sur les figures, les deux parois latérales principales 3,4 forment entre elles un angle de 90 degrés, ce qui permet de limiter le nombre de blocs modulaires à assembler pour constituer les marches d'un escalier d'angle droit, qui est l'escalier d'angle le plus courant.The triangular bases of the prism being isosceles, the two side walls 3, 4, called main side walls, are of identical dimensions. The two main side walls are arranged to form between them a determined angle. This angle can be chosen to match (or be a divider of) an angle of a swimming pool basin in which a staircase is to be formed. Advantageously, and as shown in the figures, the two main side walls 3, 4 form an angle of 90 degrees between them, which makes it possible to limit the number of modular blocks to be assembled to constitute the steps of a staircase. right angle, which is the most common corner staircase.

Les deux parois latérales principales 3, 4 comportent des moyens d'assemblage 2 pour solidariser plusieurs blocs modulaires à bancher entre eux. Ces moyens comprennent des organes de type mâle 7 et des organes de type femelle 8 permettant d'établir un assemblage par glissement entre deux blocs modulaires. Ainsi que représenté sur les figures, les organes de type mâle 7 peuvent être formés de tenons et les organes de type femelle 8 de rainures dont les formes complémentaires coopèrent pour permettre un assemblage de type queue d'aronde.The two main side walls 3, 4 comprise assembly means 2 for securing several modular blocks to be shuttered together. These means comprise male type members 7 and female type members 8 making it possible to establish a sliding connection between two modular blocks. As shown in the figures, the male-type members 7 may be formed of tenons and the female-type members 8 of grooves, the complementary shapes of which cooperate to allow an assembly of the dovetail type.

Selon l'invention et représenté en particulier sur la figure 3, le tenon présente des largeurs l, l' différentes au niveau de la première face A et de la deuxième face B du bloc modulaire. De la même manière, la rainure présente des largeurs différentes au niveau de la première et de la deuxième face A, B du bloc modulaire. Cette configuration particulière permet de bloquer le glissement d'un tenon d'un premier bloc modulaire dans une rainure de forme complémentaire d'un deuxième bloc modulaire lors de l'assemblage de deux blocs modulaires.According to the invention and shown in particular on figure 3 , the tenon has different widths l, l 'at the level of the first face A and the second face B of the modular block. Likewise, the groove has different widths at the first and second faces A, B of the modular block. This particular configuration makes it possible to block the sliding of a tenon of a first modular block in a groove of complementary shape of a second modular block during the assembly of two modular blocks.

L'assemblage de deux blocs modulaires se fait par leurs faces latérales C, D respectives; les blocs étant tête-bêche, l'un ayant sa face A orientée vers le bas et l'autre ayant sa face A orientée vers le haut, la face latérale D du premier bloc est assemblée avec la face C du second bloc, par glissement des tenons dans les rainures prévues à cet effet.The assembly of two modular blocks is done by their respective side faces C, D; the blocks being head to tail, one having its face A oriented downwards and the other having its face A oriented upwards, the lateral face D of the first block is assembled with the face C of the second block, by sliding the tenons in the grooves provided for this purpose.

De manière avantageuse, et comme illustré sur les figures 1 à 3, chaque paroi latérale principale 3, 4 présente une forme définissant une pluralité de tenons et de rainures, en particulier 2 tenons et 2 rainures, s'étendant tout le long de ces parois. En d'autres termes, les moyens d'assemblage sont intégrés aux parois latérales principales 3, 4. Cette caractéristique préférentielle simplifie la fabrication des moyens d'assemblage et favorise la cohésion des blocs modulaires assemblés.Advantageously, and as illustrated in the figures 1 to 3 , each main side wall 3, 4 has a shape defining a plurality of tenons and grooves, in particular two tenons and two grooves, extending all along these walls. In other words, the assembly means are integrated into the main side walls 3, 4. This preferred characteristic simplifies the manufacture of the assembly means and promotes the cohesion of the assembled modular blocks.

En outre, une butée 9 peut être présente à l'extrémité la plus étroite d'une rainure au moins, pour bloquer le tenon d'un autre bloc dans une position définie d'assemblage. De manière avantageuse, chaque rainure comporte à l'extrémité la plus étroite une butée permettant d'ajuster la position et de bloquer l'emboitement des tenons d'un autre bloc dans leur position finale d'assemblage.In addition, a stopper 9 may be present at the narrower end of at least one groove, to lock the tenon of another block in a defined assembly position. Advantageously, each groove comprises at the narrowest end a stopper making it possible to adjust the position and to block the interlocking of the tenons of another block in their final assembly position.

Préférentiellement, chaque tenon comporte une encoche 10 en son extrémité la plus étroite apte à coopérer avec la butée 9 de la rainure d'un autre bloc, pour le bloquer dans une position définie d'assemblage. Ainsi chaque rainure étant munie d'une butée et chaque tenon étant muni d'une encoche, l'emboitement d'un premier bloc modulaire sur un deuxième bloc modulaire sera aisément ajusté et bloqué dans sa position finale d'assemblage.Preferably, each tenon comprises a notch 10 at its narrowest end capable of cooperating with the stop 9 of the groove of another block, to block it in a defined assembly position. Thus, each groove being provided with a stop and each tenon being provided with a notch, the interlocking of a first modular block on a second modular block will be easily adjusted and locked in its final assembly position.

La figure 4 présente un assemblage formé d'une première rangée de blocs modulaires à bancher. On remarque sur cette vue l'alternance des faces exposées A, B entre des blocs modulaires adjacents, induite par le mode d'assemblage décrit plus haut.The figure 4 presents an assembly formed of a first row of modular blocks to be shuttered. Note in this view the alternation of the exposed faces A, B between adjacent modular blocks, induced by the assembly method described above.

L'empilement d'une pluralité de rangées ou de blocs modulaires à bancher peut être réalisé avec un bon alignement, par positionnement des rangées ou blocs les uns sur les autres et emmanchage d'un rail dans l'ouverture formé par l'alignement d'un compartiment traversant de chaque bloc. La dimension du rail est ajustée à la dimension du compartiment de chaque bloc, de sorte que le rail permette d'assurer l'alignement vertical de blocs modulaires empilés.Stacking of a plurality of rows or modular shuttering blocks can be achieved with good alignment, by positioning the rows or blocks on top of each other and fitting a rail into the opening formed by the alignment of 'a crossing compartment of each block. The rail size is adjusted to the compartment size of each block, so that the rail provides vertical alignment of stacked modular blocks.

L'assemblage d'une pluralité de blocs modulaires à bancher, juxtaposés en rangées, puis empilés permet la construction de différents éléments de maçonnerie.The assembly of a plurality of modular blocks for shuttering, juxtaposed in rows, then stacked, allows the construction of different masonry elements.

Selon un exemple avantageux de mise en œuvre, un tel assemblage de blocs modulaires à bancher peut être utilisé pour la fabrication d'un escalier d'angle de piscine, comme illustré sur la figure 5.According to an advantageous example of implementation, such an assembly of modular blocks for shuttering can be used for the manufacture of a swimming pool corner staircase, as illustrated in FIG. figure 5 .

La fabrication d'une piscine nécessite de couler une structure en béton, notamment pour la construction du radier et des parois de celle-ci. La mise en œuvre selon l'invention permet de réaliser le coulage du béton en une fois, pour le radier, les parois et les escaliers de piscine.The manufacture of a swimming pool requires pouring a concrete structure, in particular for the construction of the raft and the walls thereof. The implementation according to the invention allows the concrete to be poured all at once, for the raft, the walls and the stairs of the swimming pool.

L'assemblage des blocs modulaires en rangées s'effectue par emboitement des blocs les uns dans les autres par l'intermédiaire des moyens d'assemblage, tel que décrit précédemment, et sans découpe.The assembly of the modular blocks in rows is carried out by fitting the blocks into one another by means of the assembly means, as described above, and without cutting.

Chaque rangée peut venir prendre appui, en ses extrémités, sur les parois perpendiculaires du bassin de piscine. De façon facultative, des rails de support 12 peuvent être fixés sur les parois du bassin ou sur le sol pour supporter les premières rangées ; ces premières rangées pourront également être supportées par au moins un rail de support central et/ou au moins un plot fixé sur le sol. Ces rails et/ou plots sont positionnés pour affleurer le niveau du fond définitif de la piscine et permettent de régler le niveau de l'escalier, avant l'écoulement du béton.Each row can come to rest, at its ends, on the perpendicular walls of the swimming pool basin. Optionally, support rails 12 can be fixed to the walls of the basin or to the floor to support the first rows; these first rows may also be supported by at least one central support rail and / or the minus one stud fixed on the ground. These rails and / or studs are positioned to be flush with the level of the final bottom of the swimming pool and make it possible to adjust the level of the stairs, before the concrete flows.

La paroi latérale 5 des blocs modulaires constituera la face exposée de la contre marche. Et la hauteur h du bloc modulaire constituera la hauteur de marche. A titre d'exemple, cette hauteur pourra être comprise entre 5cm et 50cm, de préférence sa dimension sera de 30cm. Avantageusement, lorsque les deux parois latérales principales sont orthogonales, la profondeur de marche est définie par la demi-largeur de la paroi latérale 5 des blocs modulaires. A titre d'exemple, elle pourra être comprise entre 15 et 40cm, de préférence sa dimension sera de 30cm.The side wall 5 of the modular blocks will constitute the exposed face of the counter step. And the height h of the modular block will constitute the step height. By way of example, this height could be between 5cm and 50cm, preferably its dimension will be 30cm. Advantageously, when the two main side walls are orthogonal, the step depth is defined by the half-width of the side wall 5 of the modular blocks. By way of example, it could be between 15 and 40cm, preferably its dimension will be 30cm.

La première rangée à positionner pour l'élaboration de l'escalier est la rangée R1 de la marche M3 que l'on peut voir sur la figure 6 représentant la vue en coupe de l'escalier d'angle droit de la figure 5 selon un plan bissecteur. Celle-ci est calée contre les parois de la piscine 14 et facultativement sur les rails (12) ou plots de support. La rangée R2 de la marche M3, puis la rangée R3 de cette même marche sont ensuite empilées sur la rangée R1 pour former cette marche. Pour assurer l'alignement de cet empilement, un rail 11 est introduit verticalement dans une ouverture formée par l'alignement des compartiments traversants des blocs modulaires. A titre d'exemple et comme représenté sur la figure 2b, le rail 11 est introduit dans le compartiment 13. La largeur du rail est ajustée à la dimension des compartiments, de sorte que le rail permette d'assurer l'alignement vertical de blocs modulaires empilés et plus particulièrement de rangées de blocs modulaires empilées. La longueur du rail 11 est ajustée au nombre de rangées empilées : il doit être suffisamment long pour traverser l'empilement de blocs modulaires, assurant ainsi sa fonction d'alignement des rangées superposées.The first row to position for the development of the staircase is row R1 of the M3 step that can be seen on the figure 6 showing the sectional view of the right corner staircase of the figure 5 according to a bisector plane. This is wedged against the walls of the swimming pool 14 and optionally on the rails (12) or support studs. Row R2 of step M3, then row R3 of this same step are then stacked on row R1 to form this step. To ensure the alignment of this stack, a rail 11 is introduced vertically into an opening formed by the alignment of the through compartments of the modular blocks. By way of example and as shown in the figure 2b , the rail 11 is introduced into the compartment 13. The width of the rail is adjusted to the size of the compartments, so that the rail makes it possible to ensure the vertical alignment of stacked modular blocks and more particularly of rows of stacked modular blocks. The length of the rail 11 is adjusted to the number of stacked rows: it must be long enough to cross the stack of modular blocks, thus ensuring its function of aligning the superimposed rows.

Après assemblage de la marche M3, c'est-à-dire la superposition des trois rangées R1, R2, R3 et le positionnement du rail d'alignement, l'ensemble peut être maintenu en position par des éléments de fixations, tels que des vis, contre les parois de la piscine.After assembly of the M3 step, that is to say the superposition of the three rows R1, R2, R3 and the positioning of the alignment rail, the assembly can be held in position by fixing elements, such as screws, against the pool walls.

L'assemblage des marches M2 et M1 est ensuite réalisé de manière similaire à ce qui vient d'être décrit pour la marche M3.The assembly of the steps M2 and M1 is then carried out in a manner similar to what has just been described for the step M3.

L'assemblage de blocs modulaires tel que décrit cidessus et illustré sur la figure 5 est prêt pour l'opération subséquente de banchage. Le matériau de remplissage, comme du béton, est coulé pour réaliser le radier de la piscine et amener le sol définitif à fleur de la marche M1. Le matériau peut être coulé au niveau de l'assemblage de blocs modulaires ; il s'écoule à travers les compartiments traversants jusqu'au sol, et jusqu'au remplissage et à l'affleurement au niveau des marches M1, M2, M3.The assembly of modular blocks as described above and illustrated on the figure 5 is ready for the subsequent banking operation. The filling material, such as concrete, is poured to make the base of the swimming pool and bring the final floor flush with the step M1. The material can be poured at the assembly of modular blocks; it flows through the through compartments to the ground, and to the filling and outcropping at the level of the steps M1, M2, M3.

Après séchage, on obtient un escalier d'angle de piscine, ne nécessitant pas de découpe, coulé simultanément avec le radier et les parois de la piscine, formant donc une structure monobloc avec l'ensemble du bassin. Ses dimensions sont précises et reproductibles. De plus, le caractère monobloc confère une grande solidité à la structure.After drying, a swimming pool corner staircase is obtained, not requiring cutting, cast simultaneously with the raft and the walls of the swimming pool, thus forming a one-piece structure with the entire basin. Its dimensions are precise and reproducible. In addition, the one-piece character gives the structure great strength.

Dans l'exemple selon la figure 5, l'escalier d'angle comporte 3 marches dont les dimensions sont définies par la taille des blocs modulaires.In the example according to figure 5 , the corner staircase has 3 steps whose dimensions are defined by the size of the modular blocks.

La standardisation des dimensions d'un escalier d'angle permet avantageusement la standardisation d'enveloppes souples d'étanchéité (« liner »), conduisant à des coûts plus faibles et des délais de livraison plus courts.The standardization of the dimensions of a corner staircase advantageously allows the standardization of flexible sealing envelopes (“liner”), leading to lower costs and shorter delivery times.

Le bloc modulaire et l'assemblage par juxtaposition et/ou empilement selon l'invention ne sont pas réduits à cette seule utilisation. Ils pourront par exemple être également utilisés pour la construction d'escalier droit ou encore de parois à bancher. A cet effet, on pourra prévoir une seconde catégorie de blocs modulaires de forme différente et complémentaire à celle exposée, de manière a pouvoir définir des coffrages perdus de forme et de dimension quelconque sans nécessité ou en limitant la découpe de bloc modulaire à bancher.The modular block and the assembly by juxtaposition and / or stacking according to the invention are not reduced to this sole use. They could, for example, also be used for the construction of straight stairs or even walls to be shuttered. For this purpose, we can provide a second category of modular blocks of different shape and complementary to that exposed, so as to be able to define lost formwork of any shape and size without necessity or by limiting the cutting of modular block to shutter.
