Abstract

The staircase has a profile (6) couplable with an upper surface of a module (1) or a series of juxtaposed modules forming a step (2) of a staircase. A nosing forming part extends in an extension by aligning a lateral surface (70) forming a riser (71), of the module or the series of modules. The lateral surface forms a raised edge of the module or the series of module at a coupled state, where the edge is adapted to retain a filling material i.e. concrete, constituent of the step and situated above the upper surface of the module or the series of modules.

Description

La présente invention concerne de manière générale la réalisation d'escaliers.The present invention relates generally to the realization of stairs.

L'invention concerne plus particulièrement un escalier modulaire, de préférence pour piscine, comprenant au moins un, de préférence une pluralité de, module(s) assemblable(s) par juxtaposition et/ou superposition pour former au moins une marche, chaque module réalisé de préférence en un matériau découpable à l'aide d'une scie, affectant la forme d'un bloc parallélépipédique délimité par quatre faces latérales, une face supérieure et une face inférieure, ledit bloc étant muni d'au moins un logement traversant reliant la face supérieure et la face inférieure du module et servant à la réception d'une matière de remplissage, tel que béton, généralement par coulée.The invention more particularly relates to a modular staircase, preferably for swimming pool, comprising at least one, preferably a plurality of, module (s) assembled (s) by juxtaposition and / or superposition to form at least one step, each module realized preferably in a material cut with the aid of a saw, affecting the shape of a parallelepiped block delimited by four lateral faces, an upper face and a lower face, said block being provided with at least one through-housing connecting the upper face and the lower face of the module and for receiving a filler, such as concrete, generally by casting.

On connaît de l'état de la technique des escaliers modulaires tels que décrits ci-dessus. Dans de tels escaliers, la matière de remplissage coulée dans les modules affleure la face supérieure des modules formant marche. Il en résulte que la face supérieure de chacun desdits modules, est peu protégée vis-à-vis des sollicitations répétées qu'elle subit du fait des montées et descentes des utilisateurs. Les marches de l'escalier peuvent se dégrader alors rapidement à l'usage. Il est prévu en outre de rapporter un profilé en saillie de la contremarche. Ce profilé provoque la création de reliefs au niveau de la contremarche qui entraînent une marque visible sur le revêtement appelé "liner".Modular stairs are known from the state of the art as described above. In such stairs, the filling material poured into the modules is flush with the upper face of the step modules. As a result, the upper face of each of said modules, is little protected vis-à-vis the repeated solicitations it undergoes because of the ups and downs of users. The steps of the stairs can then degrade quickly with use. It is also expected to report a profile protruding from the riser. This profile causes the creation of reliefs at the riser which cause a visible mark on the coating called "liner".

DE1509522 décrit un escalier modulaire dans lequel la face supérieure de chaque module est protégée uniquement à l'aide d'un revêtement de protection rapporté. DE1509522 describes a modular staircase in which the upper face of each module is protected only by means of an added protective coating.

DE2921457 décrit un escalier métallique comprenant des modules creux formant marches assemblés entre eux à l'aide de cornières. EP-A-1.707.706 décrit une pièce à bancher un élément d'ouvrage, tel que des marches d'un escalier de piscine destinée à coopérer avec une pièce à bancher similaire à l'aide de premiers et deuxièmes moyens d'accrochage formant une liaison mâle-femelle de façon à former des volumes de coulée correspondant à au moins deux marches dudit escalier. DE2921457 discloses a metal staircase comprising hollow modules forming steps assembled together using angle brackets. EP-A-1707706 describes a workpiece, such as steps of a swimming pool staircase intended to cooperate with a similar bending piece, with the aid of first and second attachment means forming a male-female connection in such a way that to form casting volumes corresponding to at least two steps of said staircase.

Le but de l'invention est de proposer un escalier en particulier de piscine dont la conception permet de renforcer chaque marche vis-à-vis des sollicitations extérieures, tout en permettant une finition du revêtement appelé "liner", sur la marche, sans génération de marques ou reliefs.The object of the invention is to propose a staircase especially pool whose design can strengthen each step vis-à-vis external stresses, while allowing a finish of the coating called "liner", on the march, without generation of marks or reliefs.

Un autre but de l'invention est de permettre un assemblage stable et précis des modules entre eux, notamment des modules qui délimitent une contremarche.Another object of the invention is to allow a stable and precise assembly of the modules together, including modules that delimit a riser.

Un autre but de l'invention est de permettre la réalisation aisée de différentes formes d'escaliers, notamment des escaliers dit en angle, à partir de modules identiques. Un escalier dit en angle est un escalier dont au moins une marche présente une direction longitudinale inclinée, généralement de 45°, par rapport au plan d'une paroi contre laquelle ladite marche est en applique.Another object of the invention is to allow easy realization of different forms of stairs, including stairs said angle, from identical modules. An angled staircase is a stairway at least one step has a longitudinal inclined direction, generally 45 °, relative to the plane of a wall against which said step is applied.

A cet effet, l'invention concerne un escalier modulaire, de préférence pour piscine, comprenant au moins un, de préférence une pluralité de, module(s) assemblable(s) par juxtaposition et/ou superposition pour former au moins une marche, chaque module réalisé de préférence en un matériau découpable à l'aide d'une scie, affectant la forme d'un bloc parallélépipédique délimité par quatre faces latérales, une face supérieure et une face inférieure, ledit bloc étant muni d'au moins un logement traversant reliant la face supérieure et la face inférieure du module et servant à la réception d'une matière de remplissage, tel que béton, généralement par coulée, caractérisé en ce que ledit escalier comprend en outre au moins un profilé couplable par emboîtement avec la face supérieure du module, ou de la série de modules juxtaposés formant une marche dudit escalier, une partie du profilé formant nez de marche, cette partie formant nez de marche s'étendant, à l'état couplé audit module ou à ladite série de modules, dans le prolongement et en alignement d'une face latérale formant contremarche dudit module ou de ladite série de modules, et formant, à l'état couplé, un bord relevé dudit module ou de ladite série de modules, apte à retenir la matière de remplissage, constitutive de la marche, située au-dessus de ladite face supérieure dudit module ou de ladite série de modules.For this purpose, the invention relates to a modular staircase, preferably for swimming pool, comprising at least one, preferably a plurality of, module (s) assembled (s) by juxtaposition and / or superposition to form at least one step, each module preferably made of a material that can be cut with the aid of a saw, having the shape of a parallelepiped block delimited by four lateral faces, an upper face and a lower face, said block being provided with at least one traversing housing connecting the upper face and the lower face of the module and serving to receive a filling material, such as concrete, generally by casting, characterized in that said staircase further comprises at least one section that can be interlocked with the upper face the module, or the series of modules juxtaposed forming a step of said staircase, a portion of the step nosing profile, said step nosing portion extending, in the state coupled to said module or said series of modules, in the extension and in alignment of a face lateral riser of said module or of said series of modules, and forming, in the coupled state, a raised edge of said module or of said series of modules, adapted to retain the filling material constituting the step, located above of said upper face of said module or of said series of modules.

Le profilé de l'escalier selon l'invention permet de retenir la matière de remplissage dans le volume délimité entre ledit profilé et la contremarche formée par la marche supérieure ou par une paroi de bassin, ce qui permet de bénéficier d'une face d'usure de la marche inférieure dont l'épaisseur est importante. Autrement dit, l'utilisation d'un tel profilé permet d'augmenter l'épaisseur de matière de remplissage située au-dessus de la face supérieure de chaque module délimitant une contremarche et ainsi de renforcer la face supérieure de la marche correspondante.The profile of the staircase according to the invention makes it possible to retain the filling material in the volume delimited between said profile and the riser formed by the upper step or by a basin wall, which makes it possible to benefit from a face of wear of the lower step whose thickness is important. In other words, the use of such a profile makes it possible to increase the thickness of filling material situated above the upper face of each module defining a riser and thus to reinforce the upper face of the corresponding step.

Le profilé sert également d'élément de liaison entre les différents modules alignés et juxtaposés qui délimitent une contremarche.The profile also serves as a connecting element between the various aligned and juxtaposed modules that delimit a riser.

En outre, du fait qu'une partie du profilé s'étend dans le prolongement et en alignement d'une face latérale formant contremarche, le profilé permet d'augmenter la hauteur de marche sans créer de zones de discontinuité entre la face latérale du module et la partie du profilé formant nez de marche. Le revêtement appelé "liner", peut alors être appliqué sur la face d'usure (obtenue après coulage de la matière de remplissage) de la marche et sur la face latérale de ces modules prolongée par le profilé, sans formation de reliefs ou marques.In addition, because a portion of the profile extends in the extension and in alignment of a riser side face, the profile increases the walking height without creating discontinuity areas between the side face of the module and the part of the profile forming a stair nosing. The coating called "liner", can then be applied to the wear face (obtained after pouring the filler) of the step and the side face of these modules extended by the profile, without formation of reliefs or marks.

Selon un mode de réalisation particulier de l'escalier selon l'invention, du type formé d'une pluralité de marches obtenues par superposition et juxtaposition de modules identiques, à l'état coulé de la matière dans les modules, la marche la plus basse est de hauteur supérieure à celle des autres marches.According to a particular embodiment of the staircase according to the invention, of the type formed of a plurality of steps obtained by superposition and juxtaposition of identical modules, in the cast state of the material in the modules, the lowest step is of higher height than the other steps.

Grâce à l'utilisation d'un profilé prolongeant la face avant formant contremarche d'un module ou d'une série de modules, le volume, délimité entre ce profilé et les modules délimitant la contremarche de la marche supérieure, peut être rempli par la matière de remplissage. Les modules formant marche supérieure sont ainsi en partie masqués par le volume de matière de remplissage situé au-dessus de la face supérieure des modules formant marche inférieure. Il en résulte que la première marche est de hauteur supérieure aux autres marches.Thanks to the use of a profile extending the front face forming a riser of a module or a series of modules, the volume delimited between this section and the modules defining the riser of the top step can be filled by the filling material. The upper step modules are thus partially hidden by the volume of filler material located above the upper face of the lower step modules. As a result, the first step is higher than the other steps.

En outre, l'utilisation d'un modèle unique de module permet de simplifier la conception et de réduire le coût de l'escalier.In addition, the use of a single module model simplifies design and reduces the cost of the staircase.

Selon une autre caractéristique avantageuse de l'escalier selon l'invention, pour coupler par emboîtement la face supérieure du module, ou de la série de modules avec le profilé, la face supérieure dudit ou de chaque module comporte au moins une fente se développant sensiblement parallèlement au plan moyen d'une face latérale du module formant contremarche et s'étendant depuis une autre face latérale jusqu'à la face latérale opposée, ladite fente étant ouverte à chacune de ses extrémités et formant un logement pour la réception à emboîtement partiel du profilé.According to another advantageous characteristic of the staircase according to the invention, to couple by interlocking the upper face of the module, or the series of modules with the profile, the upper face of said or each module comprises at least one slot developing substantially parallel to the middle plane of a side face of the riser module and extending from another side face to the opposite side face, said slot being open at each of its ends and forming a housing for the partially interlocking receiving of profile.

La réalisation d'une fente est un moyen d'assemblage qui est aisé à réaliser et qui ne forme pas de saillie en face supérieure. Un tel moyen d'assemblage n'augmente donc pas l'encombrement du module.The realization of a slot is an assembly means that is easy to perform and that does not form a projection on the upper face. Such an assembly means does not increase the size of the module.

Lorsque des modules sont alignés et juxtaposés pour délimiter une contremarche, l'ouverture de chaque fente à ses extrémités permet d'engager un profilé continu dans l'alignement des fentes.When modules are aligned and juxtaposed to delimit a riser, the opening of each slot at its ends allows to engage a continuous profile in the alignment of the slots.

Selon une autre caractéristique avantageuse de l'escalier selon l'invention, la face supérieure dudit ou de chaque module comporte au moins quatre fentes se croisant à angle droit pour former un quadrilatère, au moins deux des fentes, parallèles entre elles, se développant sensiblement parallèlement au plan moyen d'une face latérale du module et s'étendant depuis une autre face latérale jusqu'à la face latérale opposée à ladite autre face, ladite fente étant ouverte à chacune de ses extrémités et formant un logement pour la réception à emboîtement partiel du profilé.According to another advantageous characteristic of the staircase according to the invention, the upper face of said or each module comprises at least four slots intersecting at right angles to form a quadrilateral, at least two of the slots, parallel to each other, developing substantially parallel to the mean plane of a lateral face of the module and extending from another lateral face to the side face opposite to said other face, said slot being open at each of its ends and forming a housing for the interlocking receiving partial profile.

La présence de fentes longeant chacune des faces latérales du module permet, quelle que soit l'orientation choisie du module, de rapporter le profilé sur la face formant contremarche. Une telle conception permet de réaliser différentes formes d'escaliers et de réduire les coûts de fabrication de tels escaliers. Dans le cas où les deux autres fentes, parallèles entre elles, ne se sont pas ouvertes à leurs extrémités, et que l'on souhaite rapporter le profilé le long d'une de ces fentes, il convient de réaliser un trait de coupe pour prolonger ladite fente de telle sorte qu'elle s'étende d'une face latérale à une autre et qu'elle soit ouvertes à ses extrémités.The presence of slots along each of the lateral faces of the module allows, whatever the chosen orientation of the module, to bring the profile on the face riser. Such a design allows for different forms of stairs and reduce the cost of manufacturing such stairs. In the case where the other two slots, parallel to each other, have not opened at their ends, and it is desired to bring the profile along one of these slots, it is necessary to make a cut line to extend said slot so that it extends from one side face to another and is open at its ends.

Selon un autre mode de réalisation particulier de l'escalier selon l'invention, du type comportant une pluralité de modules assemblés par juxtaposition et, éventuellement, par superposition pour former au moins une marche, ledit profilé est un élément continu reliant entre eux une pluralité de modules juxtaposés servant à la délimitation d'une contremarche.According to another particular embodiment of the staircase according to the invention, of the type comprising a plurality of modules assembled by juxtaposition and possibly by superposition to form at least one step, said profile is a continuous element connecting a plurality of them juxtaposed modules used to delimit a riser.

Les modules d'une rangée peuvent ainsi être précisément alignés et maintenus entre eux par le profilé continu.The modules of a row can thus be precisely aligned and held together by the continuous profile.

Selon une autre caractéristique avantageuse de l'invention, le profilé comporte un corps de base à section transversale en forme générale de L, la branche verticale dudit L étant apte à former le bord relevé de la face du module, ou de la série de modules, formant contremarche, et la branche horizontale dudit L destinée à venir en applique sur la face supérieure dudit module ou de ladite série de modules, étant munie d'une aile formant un organe mâle de raccordement à emboîtement du profilé audit module ou à ladite série de modules.According to another advantageous characteristic of the invention, the profile comprises a generally L-shaped cross-section base body, the vertical leg of said L being able to form the raised edge of the face of the module, or of the series of modules. , forming a riser, and the horizontal branch of said L intended to be applied to the upper face of said module or of said series of modules, being provided with a wing forming a male connection member with interlocking of the profile to said module or to said series of modules.

Selon une autre caractéristique avantageuse de l'invention, chaque module comporte au moins deux faces latérales opposées, dites faces d'assemblage, équipées chacune d'au moins un organe de type mâle ou femelle, lesdites faces latérales opposées étant de formes complémentaires.According to another advantageous characteristic of the invention, each module comprises at least two opposite lateral faces, called assembly faces, each equipped with at least one member of male or female type, said opposite side faces being of complementary shapes.

Selon une autre caractéristique avantageuse de l'invention, chaque face d'assemblage comporte au moins un organe mâle et un organe femelle de formes complémentaires.According to another advantageous characteristic of the invention, each assembly face comprises at least one male member and a female member of complementary shapes.

Selon une autre caractéristique avantageuse de l'invention, ledit logement traversant est divisé en quatre compartiments par deux cloisons dites verticales se croisant en formant une croix entre elles, chaque cloison passant par le plan médian vertical de chacune des faces d'une paire de faces latérales opposées.According to another advantageous characteristic of the invention, said through-housing is divided into four compartments by two so-called vertical partitions crossing one another forming a cross between them, each partition passing through the vertical median plane of each of the faces of a pair of faces. opposite sides.

Selon une autre caractéristique avantageuse de l'invention, la face supérieure dudit ou de chaque module comporte au moins un tronçon de gouttière à bords longitudinaux discontinus, s'étendant depuis une face latérale jusqu'à la face latérale opposée correspondante, et, de préférence, selon une direction parallèle au plan médian vertical des deux faces opposées.According to another advantageous characteristic of the invention, the upper face of said or each module comprises at least one gutter section with discontinuous longitudinal edges, extending from a lateral face to the corresponding opposite lateral face, and preferably , in a direction parallel to the vertical median plane of the two opposite faces.

Selon le mode de réalisation particulier de l'escalier selon l'invention, du type formé d'une pluralité de marches obtenues par superposition et juxtaposition de modules identiques, chaque module d'une marche supérieure repose sur un module d'une marche inférieure.According to the particular embodiment of the staircase according to the invention, of the type formed of a plurality of steps obtained by superposition and juxtaposition of identical modules, each module of an upper step rests on a module of a lower step.

Un tel assemblage des modules entre eux pour former plusieurs marches permet de s'exempter de pièces autres que des modules pour positionner les modules à différentes hauteurs, à l'inverse d'escalier de l'état de la technique pour lesquels les modules peuvent être montés à différentes hauteurs sur des pieux. Un tel assemblage permet en outre une économie importante en matière de remplissage.Such an assembly of modules together to form several steps allows to exempt parts other than modules to position the modules at different heights, unlike prior art stairs for which the modules can be mounted at different heights on piles. Such an assembly also allows a significant saving in filling.

De la même manière, dans le cas d'un escalier formé d'au moins une marche obtenue par juxtaposition de modules généralement identiques juxtaposés, ladite marche peut être formée d'une pluralité de rangées de modules juxtaposés pour former une marche de type plage.Similarly, in the case of a stairway formed of at least one step obtained by juxtaposition of generally identical juxtaposed modules, said step may be formed of a plurality of rows of modules juxtaposed to form a beach-type step.

En référence aux figures, l'escalier modulaire selon l'invention comprend au moins un, de préférence une pluralité de, modules 1 assemblables par juxtaposition et/ou superposition pour former au moins une marche 2.With reference to the figures, the modular staircase according to the invention comprises at least one, preferably a plurality of, modules 1 assembled by juxtaposition and / or superposition to form at least one step 2.

Dans l'exemple illustré aux figures, ledit escalier est un escalier pour piscine qui comprend une pluralité de modules 1 assemblés par juxtaposition et superposition pour former les marches 2, 21 dudit escalier. Les modules d'une marche 21 supérieure reposent sur une semelle 2' formée par des modules d'une marche 2 inférieure (voir figure 4).In the example illustrated in the figures, said staircase is a pool staircase which comprises a plurality of modules 1 assembled by juxtaposition and superposition to form the steps 2, 21 of said staircase. The modules of an upper step 21 rest on a sole 2 'formed by modules of a lower step 2 (see FIG. figure 4 ).

Chaque module 1 est réalisé de préférence en un matériau découpable à l'aide d'une scie, tel que du polystyrène. Chaque module affecte la forme d'un bloc parallélépipédique, en particulier de forme générale cubique, délimité par quatre faces latérales 7A, 7B, 7C, 7D, une face 4 supérieure et une face 5 inférieure. Les quatre faces latérales 7A, 7B, 7C, 7D sont sensiblement de mêmes dimensions. Chaque module est muni d'au moins un logement 3 traversant reliant la face 4 supérieure et la face 5 inférieure du module 1. Ledit logement 3 traversant sert à la réception d'une matière de remplissage généralement par coulée. La matière de remplissage est ici du béton.Each module 1 is preferably made of a material that can be cut with the aid of a saw, such as polystyrene. Each module has the shape of a parallelepipedal block, in particular of cubic general shape delimited by four lateral faces 7A, 7B, 7C, 7D, an upper face 4 and a lower face 5. The four lateral faces 7A, 7B, 7C, 7D are substantially of the same dimensions. Each module is provided with at least one through-hole 3 connecting the upper face 4 and the lower face of the module 1. Said through-housing 3 serves to receive a filling material generally by casting. The filling material here is concrete.

Comme illustré à la figure 4 et de manière caractéristique à l'invention, la face supérieure de chaque série de modules juxtaposés formant une marche 2, 21 dudit escalier est couplée par emboîtement avec un profilé 6 dont une partie forme nez de marche. La partie formant nez de marche dudit profilé 6 s'étend, à l'état couplé à ladite série de modules 1, dans le prolongement et en alignement de la face latérale 70 formant contremarche de ladite série de modules 1. La partie formant nez de marche dudit profilé 6 forme également, à l'état couplé, un bord relevé de ladite série de modules 1, apte à retenir la matière de remplissage (non représentée), constitutive de la marche 2, située au-dessus de la face supérieure de ladite série de modules 1.As illustrated in figure 4 and in a characteristic manner to the invention, the upper face of each series of juxtaposed modules forming a step 2, 21 of said staircase is coupled by interlocking with a profile 6, a part forming a step form. The step nose portion of said profile 6 extends, in the state coupled to said series of modules 1, in the extension and alignment of the lateral face 70 forming the riser of said series of modules 1. The nose portion of operation of said profile 6 also forms, in the coupled state, a raised edge of said series of modules 1, adapted to retain the filling material (not shown), constituting the step 2, located above the upper face of said series of modules 1.

Pour coupler par emboîtement la face supérieure de chaque série de modules délimitant une contremarche, avec le profilé 6, la face 4 supérieure de chaque module 1 comporte au moins une fente 8A se développant sensiblement parallèlement au plan moyen de la face 7A latérale du module 1 formant contremarche et s'étendant depuis la face latérale 7B jusqu'à la face latérale 7D opposée. On entend par plan moyen d'une face, le plan passant par les arêtes latérales de ladite face. Ladite fente 8A est ouverte à chacune de ses extrémités et forme un logement pour la réception à emboîtement partiel du profilé 6.To couple by interlocking the upper face of each series of modules defining a riser, with the profile 6, the upper face 4 of each module 1 comprises at least one slot 8A developing substantially parallel to the average plane of the lateral face 7A of the riser module 1 and extending from the side face 7B to the opposite side face 7D. Mean plane of a face, the plane passing through the lateral edges of said face. Said slot 8A is open at each of its ends and forms a housing for the partial fitting reception of the profile 6.

Dans l'exemple illustré aux figures et plus particulièrement à la figure 1, la face 4 supérieure de chaque module 1 comporte quatre fentes 8A, 8B, 8C, 8D se croisant à angle droit pour former un quadrilatère. Les fentes 8A et 8C, parallèles entre elles, se développent sensiblement parallèlement au plan moyen des faces 7A et 7C latérales du module 1 et s'étendent depuis une autre face latérale 7B jusqu'à la face latérale 7D opposée correspondante. Chaque fente 8A et 8C est ouverte à chacune de ses extrémités et forme un logement pour la réception à emboîtement partiel du profilé 6. La présence des fentes 8B, 8D, orthogonales aux fentes 8A, 8C, permet, comme détaillé ci-après et illustré aux figures 5a, 5b, 5c, de réaliser un escalier comportant plusieurs zones de descente et de montée. Dans l'exemple illustré à la figure 1, les extrémités de ces fentes 8B, 8D ne sont pas ouvertes sur les faces latérales 7A, 7C pour ne pas fragiliser les coins du module. Ce n'est qu'à la réalisation de l'escalier et si l'on a besoin de coupler un profilé à la fente 8B ou 8D que celle-ci est ouverte à ses extrémités par des traits de coupe. En variante, on peut prévoir que chaque fente 8A, 8B, 8C, 8D soit ouverte à chacune de ses extrémités au moment de la fabrication du module.In the example illustrated in the figures and more particularly in the figure 1 , the upper face 4 of each module 1 comprises four slots 8A, 8B, 8C, 8D intersecting at right angles to form a quadrilateral. The slots 8A and 8C, parallel to each other, develop substantially parallel to the mean plane of the side faces 7A and 7C of the module 1 and extend from another side face 7B to the corresponding opposite side face 7D. Each slot 8A and 8C is open at each of its ends and forms a housing for the partial fitting reception of the profile 6. The presence of the slots 8B, 8D, orthogonal to the slots 8A, 8C, allows, as detailed below and illustrated to the figures 5a , 5b , 5c , to make a staircase with several areas of descent and ascent. In the example shown in figure 1 , the ends of these slots 8B, 8D are not open on the side faces 7A, 7C so as not to weaken the corners of the module. It is only at the completion of the staircase and if it is necessary to couple a profile to the slot 8B or 8D that it is open at its ends by cutting lines. Alternatively, it can be provided that each slot 8A, 8B, 8C, 8D is open at each of its ends at the time of manufacture of the module.

Comme illustré plus particulièrement aux figures 2 et 3, le profilé 6 comporte un corps de base à section transversale en forme générale de L. A l'état couplé du profilé 6 à la série de modules 1, la branche verticale 15 dudit L forme un bord relevé de la face de la série de modules formant contremarche et la branche horizontale 14 dudit L vient en applique sur la face supérieure de ladite série de modules. Ladite branche horizontale 14 est munie d'une aile 13 formant un organe mâle de raccordement à emboîtement du profilé 6 à ladite série de modules. L'aile 13, qui s'étend sensiblement perpendiculairement à la branche horizontale 14, peut être obtenue par pliage à angle droit du bord longitudinal de ladite branche horizontale 14. En particulier, la branche 14 d'applique s'étend sensiblement perpendiculairement à l'aile 13 et sur une longueur correspondant à la distance entre la fente du module dans laquelle doit être insérée cette aile 13 et la face du module formant contremarche.As illustrated more particularly in Figures 2 and 3 , the profile 6 comprises a base body with a generally L-shaped cross-section. In the coupled state of the profile 6 to the series of modules 1, the vertical branch 15 of said L forms a raised edge of the face of the series of riser modules and the horizontal branch 14 of said L comes to apply on the upper face of said series of modules. Said horizontal limb 14 is provided with a flange 13 forming a male interlocking connection member of the profile 6 to said series of modules. The wing 13, which extends substantially perpendicularly to the horizontal branch 14, can be obtained by bending at right angles to the longitudinal edge of said horizontal branch 14. In particular, the branch 14 applies substantially perpendicular to the wall. wing 13 and a length corresponding to the distance between the slot of the module into which this wing 13 must be inserted and the face of the riser module.

En outre, le bord libre supérieur de la branche verticale 15 comporte un retour 16, replié vers l'aile 13 et la branche horizontale 14, c'est à dire replié vers l'intérieur du volume délimité par le profilé 6 et la contremarche 71 de la marche supérieure 21 à l'état assemblé des modules et du profilé correspondant (voir figure 4). Ce retour 16 sert de partie d'accrochage du profilé 6 dans le béton, lorsque celui-ci est coulé dans les modules et remplit l'espace délimité par le profilé et la contremarche de la marche supérieure. Comme illustré à la figure 3, l'aile 13 s'étend parallèlement à la branche verticale 15 et la partie du retour 16 qui forme le bord supérieur du profilé s'étend parallèlement à la branche horizontale 14.In addition, the upper free edge of the vertical leg 15 has a return 16, folded towards the flange 13 and the horizontal leg 14, that is to say folded towards the inside of the volume delimited by the section 6 and the riser 71 of the upper step 21 in the assembled state of the modules and the corresponding profile (see figure 4 ). This return 16 serves as attachment part of the profile 6 in the concrete, when it is poured into the modules and fills the space defined by the profile and the riser of the upper step. As illustrated in figure 3 , the wing 13 extends parallel to the vertical leg 15 and the portion of the return 16 which forms the upper edge of the profile extends parallel to the horizontal leg 14.

Dans l'exemple illustré à la figure 4, les modules sont juxtaposés et alignés pour former une rangée dite avant qui délimite une contremarche 70. D'autres rangées de modules sont accolées derrière ladite rangée avant pour former la semelle 2', ou support, sur laquelle reposent les modules de la ou des marche(s) 21 supérieure(s). Lorsque le béton est coulé dans les modules assemblés, le volume délimité entre ledit profilé 6 et la contremarche 71 de la marche supérieure 21 se remplit de béton. La marche 2 la plus basse, c'est-à-dire celle qui repose directement sur le sol et non pas sur d'autres modules, est alors de hauteur supérieure à celle des autres marches 21.In the example shown in figure 4 , the modules are juxtaposed and aligned to form a so-called front row which delimits a riser 70. Other rows of modules are contiguous behind said front row to form the sole 2 ', or support, on which the modules of the or step (s) 21 top (s). When the concrete is poured into the assembled modules, the volume delimited between said profile 6 and the riser 71 of the upper step 21 is filled with concrete. The lowest step 2, that is to say that which rests directly on the ground and not on other modules, is then higher than the other steps 21.

De préférence, comme illustré à la figure 4, le profilé 6 est un élément continu reliant entre eux une pluralité de modules 1 juxtaposés servant à la délimitation d'une contremarche 70, ledit profilé 6 étant de longueur sensiblement égale à celle de la marche 2. Le profilé 6 est inséré dans chaque fente longeant la face avant de la rangée de modules 1 délimitant la contremarche 70. Le profilé inséré dans les fentes des modules permet de maintenir alignés les modules 1 entre eux. En variante, on peut prévoir que le profilé soit formé de plusieurs tronçons assemblés en bout à bout.Preferably, as illustrated in figure 4 , the profile 6 is a continuous element interconnecting a plurality of juxtaposed modules 1 serving to delimit a riser 70, said profile 6 being of length substantially equal to that of the step 2. The profile 6 is inserted into each slot along the face before the row of modules 1 defining the riser 70. The profile inserted into the slots of the modules keeps the modules 1 aligned with each other. Alternatively, it can be provided that the profile is formed of several sections assembled end to end.

Chaque module 1 comporte au moins deux faces 7B, 7D latérales opposées, dites faces d'assemblage, équipées chacune d'au moins un organe de type mâle ou femelle, lesdites faces 7B, 7D latérales opposées étant de formes complémentaires. De préférence, comme illustré plus particulièrement à la figure 1, chaque face d'assemblage est équipée d'un organe mâle 10B, 10D, tel qu'une queue d'aronde et d'un organe femelle 9B, 9D, tel qu'une ouverture de forme complémentaire de ladite queue d'aronde, autorisant un assemblage d'une face latérale d'un module avec la face latérale opposée correspondante d'un autre module identique. Il est ainsi possible de réaliser un escalier par assemblage de modules identiques. L'organe mâle de chaque face d'assemblage est apte, après découpe, à être logé dans l'organe femelle de ladite face d'assemblage.Each module 1 comprises at least two opposite lateral faces 7B, 7D, called assembly faces, each equipped with at least one member of male or female type, said faces 7B, 7D opposite side being of complementary shapes. Preferably, as illustrated more particularly in figure 1 each connecting face is equipped with a male member 10B, 10D, such as a dovetail and a female member 9B, 9D, such as an opening of complementary shape to said dovetail, allowing assembly of a side face of a module with the corresponding opposite side face of another identical module. It is thus possible to make a staircase by assembling identical modules. The male member of each assembly face is adapted, after cutting, to be housed in the female member of said assembly face.

Les organes mâle 10B, 10D et femelle 9B, 9D des faces d'assemblage 7B, 7D sont disposés symétriquement par rapport à l'axe A1 du parallélépipède et les deux autres faces latérales 7A, 7C de chaque module 1 sont lisses de manière à pouvoir constituer une face formant contremarche. L'axe A1 est défini comme l'axe passant par le centre de la section carrée du module et qui s'étend parallèlement à l'axe du logement 3, c'est-à-dire verticalement. Ainsi, chaque module 1 peut être indifféremment tourné de 180° autour dudit axe A1 pour être assemblé à des modules identiques.The male members 10B, 10D and female 9B, 9D of the assembly faces 7B, 7D are arranged symmetrically with respect to the axis A1 of the parallelepiped and the other two lateral faces 7A, 7C of each module 1 are smooth so as to be able to constitute a riser face. The axis A1 is defined as the axis passing through the center of the square section of the module and which extends parallel to the axis of the housing 3, that is to say vertically. Thus, each module 1 can be indifferently rotated 180 ° about said axis A1 to be assembled to identical modules.

En outre, comme illustré à la figure 1, la face supérieure 4 de chaque module 1 présente des moyens d'assemblage 11 de type mâle, complémentaires de moyens d'assemblage de type femelle (non représentés) ménagés sur la face inférieure 5 de chaque module 1. Dans l'exemple illustré à la figure 1, les moyens d'assemblage de type mâle 11 sont formés par le rebord du logement 3 qui s'étend en saillie de la face supérieure 4 et par la cloison 17 (détaillée ci-après) qui s'étend également en saillie de la face supérieure 4. En variante, on peut prévoir que les faces 4 inférieure et 5 supérieure soient de même géométrie de manière à permettre un positionnement aisé et rapide des modules 1 entre eux, sans avoir à différencier la face supérieure de la face inférieure.In addition, as illustrated in figure 1 the upper face 4 of each module 1 has assembly means 11 of the male type, complementary to female type assembly means (not shown) provided on the lower face 5 of each module 1. In the example illustrated in FIG. the figure 1 , the male-type assembly means 11 are formed by the edge of the housing 3 which extends projecting from the upper face 4 and the partition 17 (detailed below) which also extends in projection from the upper face 4. As a variant, it is possible for the lower and upper faces 4 to be provided are of the same geometry so as to allow easy and fast positioning of the modules 1 between them, without having to differentiate the upper face of the lower face.

Ledit logement traversant 3 est divisé en quatre compartiments par deux cloisons 17, 18, dites verticales, perpendiculaires entre elles et se croisant à la manière d'un croisillon. Chaque cloison 17, 18 passe par le plan médian vertical de chacune des faces d'une paire de faces 7A, 7C ou 7B, 7D latérales opposées. La configuration géométrique de ces cloisons 17, 18 permet un découpage aisé du module selon une diagonale de sa section carrée. En outre, après découpe en diagonale dudit module, l'opérateur obtient deux pièces de section triangulaire et les portions de cloison restantes sur chaque pièce forment des nervures de rigidification de ladite pièce. Une telle découpe en diagonale des modules est utilisée, notamment pour la réalisation d'escalier en angle comme détaillé ci-après et illustré aux figures 4a et 4b.Said through housing 3 is divided into four compartments by two partitions 17, 18, said vertical, perpendicular to each other and intersecting in the manner of a cross. Each partition 17, 18 passes through the vertical median plane of each of the faces of a pair of opposite faces 7A, 7C or 7B, 7D. The geometric configuration of these partitions 17, 18 allows easy cutting of the module along a diagonal of its square section. In addition, after cutting diagonally of said module, the operator obtains two pieces of triangular section and the remaining partition portions on each piece form stiffening ribs of said part. Such a diagonal cut of the modules is used, in particular for the realization of angle staircase as detailed below and illustrated at Figures 4a and 4b .

De manière à faciliter la découpe du module, si nécessaire, la face 4 supérieure et, éventuellement la face inférieure, dudit module comportent des traits de coupe 19, 20 qui constituent des repères de découpe. Comme illustré à la figure 1, il est prévu des traits de coupe 20 orientés selon les diagonales de la face supérieure 4 de chaque module.In order to facilitate the cutting of the module, if necessary, the upper face 4 and possibly the lower face of said module include cutting lines 19, 20 which constitute cutting marks. As illustrated in figure 1 , there are provided cutting lines 20 oriented along the diagonals of the upper face 4 of each module.

Il est également prévu des traits de coupe 19 orientés selon un plan de coupe parallèle aux faces latérales 7B, 7D d'assemblage pour ajuster si nécessaire la longueur du module en fonction des dimensions de la piscine.Cutting lines 19 oriented along a cutting plane parallel to the lateral faces 7B, 7D of assembly are also provided to adjust the length of the module if necessary depending on the dimensions of the pool.

En outre, la face 4 supérieure de chaque module 1 comporte un tronçon de gouttière 12 à bords longitudinaux discontinus. Ce tronçon de gouttière 12 s'étend depuis la face 7B latérale jusqu'à la face 7D latérale opposée correspondante.In addition, the upper face 4 of each module 1 comprises a gutter section 12 with discontinuous longitudinal edges. This gutter section 12 extends from the lateral face 7B to the opposite lateral side face 7D corresponding.

Chaque tronçon de gouttière 12 est de préférence centré, c'est-à-dire qu'il s'étend selon une direction parallèle au plan médian vertical des deux faces 7B, 7D opposées. Ainsi, les tronçons de gouttière des modules d'une rangée parallèle à la contremarche peuvent être alignés pour former une gouttière. Lorsque le béton est coulé dans les modules, il s'écoule ainsi le long des gouttières de manière à lier lesdits modules entre eux. Grâce au profilé, le béton coulé s'étend au-dessus de la face supérieure des modules correspondants jusqu'au bord libre supérieur dudit profilé. Le béton répandu dans la gouttière forme alors, à l'état durci, une barre solidaire de la rangée de modules. Ainsi, lorsqu'il est nécessaire de modifier la structure de l'escalier, une rangée de modules peut être extraite aisément. En outre, une telle barre de béton assure la cohésion des modules d'une même rangée entre eux.Each section of gutter 12 is preferably centered, that is to say that it extends in a direction parallel to the vertical median plane of the two faces 7B, 7D opposite. Thus, the gutter sections of the modules of a row parallel to the riser can be aligned to form a gutter. When the concrete is poured into the modules, it flows along the gutters so as to bind said modules together. With the profile, the poured concrete extends above the upper face of the corresponding modules to the upper free edge of said profile. The concrete poured into the gutter then forms, in the cured state, a bar integral with the row of modules. Thus, when it is necessary to modify the structure of the staircase, a row of modules can be extracted easily. In addition, such a concrete bar ensures the cohesion of the modules of the same row between them.

Les figures 4, 4a à 4e et 5a, 5b, 5c présentent différentes formes d'escaliers réalisables à partir des modules selon l'invention.The figures 4 , 4a to 4e and 5a , 5b , 5c present different forms of stairs achievable from the modules according to the invention.

L'escalier illustré à la figure 4 est un escalier de type classique, selon lequel toutes les marches ont la même longueur et chaque marche présente une seule face formant contremarche.The staircase shown at figure 4 is a classic type of staircase, according to which all the steps have the same length and each step has a single face forming a riser.

Dans l'escalier illustré aux figures 5a, 5b, chaque marche présente deux faces 70, 70' orthogonales formant contremarche de sorte que ledit escalier comporte deux zones de descente et de montée. Chaque marche 21 supérieure à une autre marche 2 dite inférieure est disposée en retrait des modules de la marche 2 qui délimitent les deux faces 70, 70' formant contremarche. La réalisation de fentes sur la périphérie de la face supérieure de chacun des modules permet d'obtenir une face supérieure de marche 2 présentant deux longues fentes de couplage à un profilé, le long de chacune des faces 70, 70' formant contremarche, chacune desdites longues fentes de couplage étant obtenue par juxtaposition d'une fente d'un module aux fentes d'autres modules. Comme rappelé ci-dessus, si les fentes 8C ou 8D des modules délimitant la face 70 formant contremarche ne sont pas ouvertes à leurs extrémités (comme c'est le cas du module illustré à la figure 1), des traits de coupes sont réalisés par l'opérateur pour l'une des fentes 8C ou 8D afin de permettre l'insertion du profilé 6' dans ladite fente. Les deux longues fentes de couplage ainsi obtenues sur face supérieure de la marche 2 reçoivent deux profilés 6, 6' dont les extrémités d'assemblage sont à coupe d'onglet pour permettre un bon assemblage desdits profilés 6, 6' entre eux.In the staircase shown at figures 5a , 5b each step has two orthogonal faces 70, 70 'forming a riser so that said staircase has two downward and upward zones. Each step 21 greater than another step 2 said lower is arranged behind the modules of the step 2 which delimit the two faces 70, 70 'forming a riser. The production of slots on the periphery of the upper face of each of the modules makes it possible to obtain an upper running face 2 having two long profile coupling slots, along each of the riser faces 70, 70 ', each of said long coupling slots being obtained by juxtaposing a slot of a module with slots other modules. As mentioned above, if the slots 8C or 8D of the modules defining the face 70 forming a riser are not open at their ends (as is the case of the module illustrated in FIG. figure 1 ), cuts are made by the operator for one of the slots 8C or 8D to allow the insertion of the profile 6 'in said slot. The two long coupling slots thus obtained on the upper face of the step 2 receive two profiles 6, 6 'whose assembly ends are mitered to allow a good assembly of said sections 6, 6' between them.

L'escalier illustré à la figure 5c est une variante de réalisation de l'escalier illustré aux figures 5a, 5b. Selon cette variante, les modules délimitant la face 70' formant contremarche sont orientés de telle sorte que leurs tronçons de gouttières s'étendent parallèlement au profilé 6'. Ainsi, à la différence des tronçons de gouttière des modules de l'escalier selon les figures 5a et 5b, qui sont tous parallèles entre eux, les tronçons de gouttière des modules délimitant la face 70 s'étendent orthogonalement aux tronçons de gouttière des modules délimitant la face 70'.The staircase shown at figure 5c is an alternative embodiment of the staircase shown in figures 5a , 5b . According to this variant, the modules defining the face 70 'forming a riser are oriented such that their sections of gutters extend parallel to the profile 6'. Thus, unlike the gutter sections of the stair modules according to the figures 5a and 5b , Which are all parallel to each other, the gutter sections of the modules delimiting the face 70 extend orthogonally to the gutter sections of the modules delimiting the face 70 '.

Selon une variante non illustrée, on peut prévoir que chaque marche présente une gouttière continue, en forme de L, qui longe les faces 70, 70', formant contremarches, en remplaçant le module formant le coin desdites contremarches, par un assemblage de deux pièces de section triangulaire issues de la découpe de deux modules en diagonale. L'un des deux modules est coupé suivant l'une de ses diagonales et l'autre module est coupé suivant l'autre diagonale. Il suffit alors d'assembler l'une des pièces découpées d'un module avec l'une des pièces découpées de l'autre module pour reformer un module dont le tronçon de gouttière forme un L.According to a variant not illustrated, it can be provided that each step has a continuous channel, L-shaped, which runs along the faces 70, 70 'forming risers, replacing the module forming the corner of said risers, by an assembly of two parts of triangular section from the cutting of two modules diagonally. One of the two modules is cut along one of its diagonals and the other module is cut along the other diagonal. It is then sufficient to assemble one of the cut pieces of a module with one of the cut pieces of the other module to reform a module whose gutter section forms an L.

Les figures 4a, 4b illustrent différentes formes d'escalier d'angle pour piscine réalisables à partir des modules selon l'invention. Les parties d'angles de ces escaliers sont obtenues comme expliqué ci-dessus par découpage en diagonale des modules. La figure 4a présente un escalier à double zone de descente et de montée qui est disposé dans un coin tronqué d'une piscine. La figure 4b illustre un escalier à simple zone de descente et de montée qui est également disposé dans un coin tronqué d'une piscine. En particulier, chaque marche de cet escalier forme en vue de dessus un trapèze isocèle.The Figures 4a, 4b illustrate different forms of swimming pool angle stairway that can be made from the modules according to the invention. The corner portions of these stairs are obtained as explained above by diagonal cutting of the modules. The figure 4a presents a double zone staircase descent and climb that is arranged in a truncated corner of a pool. The figure 4b illustrates a simple downhill and uphill staircase that is also arranged in a truncated corner of a pool. In particular, each step of this staircase forms in plan view an isosceles trapezium.

La figure 4e est une vue d'un escalier dont chaque marche présente en vue de dessus la forme d'un quadrilatère de manière à offrir trois zones de descente et de montée dans des directions faisant un angle de 90° entre elles.The figure 4e is a view of a staircase, each step of which has a plan view of a quadrilateral so as to provide three zones of descent and rise in directions at an angle of 90 ° between them.

La figure 4d est un escalier présentant une seule zone de descente et de montée et dont une marche (la plus haute) présente une face d'usure formée par la face supérieure de deux rangées de modules tandis que la face d'usure des autres marches est formée d'une seule rangée de modules.The figure 4d is a staircase presenting a single downhill and upward zone and one of which (the highest) has a wear face formed by the upper face of two rows of modules while the wear face of the other steps is formed of 'a single row of modules.
