Description

Domaine techniqueTechnical area

L'invention se rapporte au domaine des piscines, spas et jacuzzis. Plus particulièrement, l'invention se rapporte aux piscines, spas et jacuzzis comprenant un escalier afin de descendre dans un bassin et de sortir du bassin. Spécifiquement, l'invention se rapporte à une piscine, spa ou jacuzzi comprenant un escalier dont les marches d'escalier sont dans un bloc de matière léger.The invention relates to the field of swimming pools, spas and jacuzzis. More particularly, the invention relates to swimming pools, spas and jacuzzis comprising a staircase to go down into a pool and out of the pool. Specifically, the invention relates to a swimming pool, spa or jacuzzi including a staircase whose steps are in a block of light material.

En fonction du type de piscine, il existe différents moyens pour descendre et sortir du bassin d'une piscine. Par exemple, pour les piscines dont la structure est enterrée et réalisée en béton, il est possible d'ajouter une structure surnuméraire, par exemple en plastique, à la piscine pour avoir un escalier, comme par exemple l'escalier pour piscine décrit dans le document US5916099 . Cependant, ce type d'escalier nécessite de fabriquer un moule, entrainant un coût et rendant impossible la modularité de l'escalier pour l'adapter à différentes formes de bassins de piscines. De plus, la manutention d'un tel escalier est malaisée. Enfin, il faut des moyens de fixation particuliers pour relier l'escalier à la piscine, compliquant ainsi les étapes de pose de l'escalier.Depending on the type of swimming pool, there are different ways to get out and leave the pool of a pool. For example, for pools whose structure is buried and made of concrete, it is possible to add a supernumerary structure, for example plastic, to the pool to have a staircase, such as the pool staircase described in the document US5916099 . However, this type of staircase requires the manufacture of a mold, causing a cost and making it impossible for the modularity of the staircase to adapt it to different forms of pool pools. In addition, the handling of such a staircase is difficult. Finally, it requires special fastening means to connect the stairs to the pool, thus complicating the steps of laying the stairs.

Il est également possible d'intégrer l'escalier à la structure de la piscine. Une telle structure est par exemple décrite dans le document EP2568098 . Des blocs de polystyrène creux et ouverts sont placés de façon à former un escalier. Un béton est ensuite coulé dans les blocs afin d'obtenir une structure solide et résistante pouvant faire office d'escalier. Ce type d'escalier présente cependant un certain nombre d'inconvénients, notamment liés à la durée de construction importante de l'escalier et des difficultés techniques survenant lors de leur mise en place. Ainsi, le temps pour mettre en place ce type d'escalier est relativement long : il faut dans un premier temps poser les blocs de polystyrène, ensuite couler le béton, et attendre que le béton sèche totalement avant de passer aux étapes ultérieures de la construction de la piscine. Ceci oblige également le constructeur de la piscine à disposer d'un outillage relativement encombrant afin de préparer et couler le béton. De plus, lorsque la piscine se trouve en extérieur, il peut dans certaines conditions climatiques être impossible de procéder à la mise en place de l'escalier. Ensuite, lorsque l'escalier est endommagé ou doit être rénové, sa reconstruction peut être une opération extrêmement pénible lorsque l'escalier comprend au moins une partie en béton, demandant de détruire ces structures en béton. De plus, ce type d'escalier nécessite la formation des blocs de polystyrène à partir de moules relativement complexes et coûteux, réduisant ainsi l'intérêt pour ces blocs.It is also possible to integrate the staircase to the structure of the pool. Such a structure is for example described in the document EP2568098 . Hollow and open polystyrene blocks are placed to form a staircase. Concrete is then poured into the blocks to obtain a solid and resistant structure that can act as a staircase. This type of staircase, however, has a number of disadvantages, particularly related to the significant construction time of the staircase and technical difficulties occurring during their establishment. Thus, the time to set up this type of staircase is relatively long: it is first necessary to lay the polystyrene blocks, then pour the concrete, and wait until the concrete completely dry before moving to the next stages of construction of the swimming pool. This also requires the builder of the pool to have relatively bulky tools to prepare and pour the concrete. In addition, when the pool is outside, it can in certain climatic conditions be impossible to proceed with the installation of the stairs. Then, when the staircase is damaged or needs to be renovated, rebuilding it can be an extremely painful operation when the staircase includes at least a concrete part, asking to destroy these concrete structures. In addition, this type of stair requires the formation of polystyrene blocks from relatively complex and expensive molds, thus reducing the interest for these blocks.

Les documents FR2773188 , US2013/007956 et US5678256 portent également sur des bassins (piscine, baignoire) munis d'un escalier. Plus particulièrement le document FR2773188 décrit des escaliers pour piscine comme étant des profilés en plastique ou en métal ou comme étant des structures en béton raccordées au gros œuvre. Le document US2013/007956 décrit des escaliers formés de blocs solides et lourds tels que des blocs en béton ou en brique. Le document US5678256 décrit un escalier fabriqué à partir de structures rigides comme de l'acier, des moulages plastiques ou des structures en béton.The documents FR2773188 , US2013 / 007956 and US5678256 also cover pools (swimming pool, bathtub) equipped with a staircase. More particularly the document FR2773188 describes swimming pool stairs as plastic or metal profiles or as concrete structures connected to the shell. The document US2013 / 007956 describes stairs made of solid and heavy blocks such as concrete or brick blocks. The document US5678256 describes a staircase made from rigid structures such as steel, plastic moldings or concrete structures.

Il existe donc un besoin pour une piscine comprenant un escalier dont les éléments constituants l'escalier ou les marches de l'escalier sont faciles à fabriquer et légers, dont la mise en place est rapide, sans avoir besoin de recourir à de couteux ou complexes moyens de fixation de l'escalier à la structure de la piscine et/ou à des moyens de solidification des blocs de l'escalier, tels que par exemple un bétonnage.There is therefore a need for a swimming pool comprising a staircase whose elements constituting the staircase or steps of the staircase are easy to manufacture and lightweight, the implementation of which is fast, without the need to resort to expensive or complex means for fixing the stairway to the swimming pool structure and / or solidification means for the stair blocks, such as, for example, concreting.

Résumé de l'inventionSummary of the invention

Suivant un premier aspect, l'invention concerne une piscine selon la revendication 1 comprenant un bassin, ledit bassin présentant un fond et au moins une paroi latérale, un escalier, ledit escalier étant indépendant du bassin et comprenant au moins une surface inférieure, ladite surface inférieure reposant sur le fond de la piscine, ledit escalier étant formé d'au moins un bloc de matière, de manière en chacun des au moins un bloc est fermé et plein, et en ce qu'un revêtement imperméable recouvre imperméablement au moins l'escalier, caractérise en ce que chacun des au moins un bloc ayant une masse volumique inférieure à 500 kg/m3.According to a first aspect, the invention relates to a swimming pool according to claim 1 comprising a pool, said pool having a bottom and at least one side wall, a staircase, said staircase being independent of the pool and comprising at least one lower surface, said surface lower part resting on the bottom of the pool, said staircase being formed of at least one block of material, so that in each of the at least one block is closed and solid, and in that an impermeable covering imperviously covers at least the staircase, characterized in that each of the at least one block having a density of less than 500 kg / m3.

Avec une telle piscine, les marches de l'escalier sont constituées par des blocs de matière dont la surface supérieure est pleine. Ces blocs sont légers, permettant aisément leur manutention par une personne isolée. La construction de l'escalier est plus rapide car aucun béton ne doit être coulé pour remplir et solidifier les blocs de matière. Grâce à l'isolation de l'escalier, les blocs ne sont pas en contact avec l'eau présente dans le bassin de la piscine. De plus, du fait de la nature de ces blocs, il est extrêmement simple d'adapter les blocs à une forme particulière du bassin de la piscine, sans avoir à créer un moule particulier pour la fabrication du bloc de matière. Il en résulte une piscine avec un escalier dont la pose est grandement facilitée, et pouvant être réalisée rapidement par une personne isolée sans faire appel à des dispositifs pour préparer ou couler un béton, ou pour fixer l'escalier.With such a pool, the steps of the staircase are constituted by blocks of material whose upper surface is full. These blocks are lightweight, allowing easy handling by an individual. The construction of the staircase is faster because no concrete must be poured to fill and solidify the blocks of material. Thanks to the insulation of the stairs, the blocks are not in contact with the water present in the swimming pool. In addition, because of the nature of these blocks, it is extremely simple to adapt the blocks to a particular shape of the pool of the pool, without having to create a particular mold for the manufacture of the block of material. The result is a pool with a staircase whose installation is greatly facilitated, and can be performed quickly by an isolated person without using devices to prepare or pour a concrete, or to fix the stairs.

Selon un mode de réalisation préféré de l'invention, l'au moins un bloc de matière est un bloc plein. Ces blocs présentent une meilleure résistance aux forces de compression et sont donc encore plus adaptés pour constituer les marches d'un escalier car ils se déforment plus difficilement, et la durée de vie de l'escalier est donc améliorée. Ces blocs pleins conservent les mêmes avantages que les blocs fermés sur leur face supérieure, à savoir une légèreté suffisante pour être manipulés par une personne seule. Il en résulte un escalier toujours plus léger que les escaliers de l'art antérieur, mais qui présente des propriétés de solidité et de robustesse encore plus satisfaisantes dans le cadre d'application de l'invention.According to a preferred embodiment of the invention, the at least one block of material is a solid block. These blocks have a better resistance to compression forces and are therefore even more suitable for constituting the steps of a staircase because they deform more difficultly, and the life of the staircase is improved. These solid blocks retain the same advantages as the closed blocks on their upper face, namely a light enough to be handled by a single person. This results in a staircase always lighter than the stairs of the prior art, but which has properties of strength and robustness even more satisfactory in the context of application of the invention.

Selon une forme de réalisation particulière, le revêtement imperméable recouvrant l'escalier se prolonge en recouvrant en outre imperméablement le fond de la piscine et l'au moins une paroi latérale. Selon ce mode de réalisation particulier, l'ensemble comprenant le fond de la piscine et les parois latérales de la piscine est recouvert du même revêtement imperméable que l'escalier, permettant d'améliorer l'étanchéité générale de l'ensemble, et plus particulièrement de l'escalier.According to a particular embodiment, the impervious coating covering the staircase is extended by further covering the bottom of the pool and the at least one side wall. According to this particular embodiment, the assembly comprising the bottom of the pool and the side walls of the pool is covered with the same impermeable coating as the staircase, to improve the overall tightness of the whole, and more particularly from the stairs.

L'invention concerne également une méthode selon la revendication 9 pour construire une piscine. La méthode comprend les étapes suivantes :

  1. a) fourniture d'une piscine comprenant un bassin, ledit bassin comprenant un fond et au moins une paroi latérale et d'un escalier formé par au moins un bloc de matière, b) pose de l'escalier sur le fond de la piscine, ladite méthode étant caractérisée en ce que ladite étape de fourniture d'un escalier est une étape de fourniture d'un escalier formé par au moins un bloc de matière fermé et plein, chacun desdits au moins un bloc ayant une masse volumique inférieure à 500 kg/m3 , et en ce qu'elle comprend une étape c) de recouvrement imperméable d'au moins l'escalier par un revêtement imperméable adapté pour rendre le bassin étanche.
Un autre procédé alternatif est décrit dans une méthode selon la revendication 10.The invention also relates to a method according to claim 9 for constructing a pool. The method includes the following steps:
  1. a) providing a pool comprising a pool, said pool comprising a bottom and at least one side wall and a staircase formed by at least one block of material, b) laying a stairway on the bottom of the pool, said method being characterized in that said step of providing a stair is a step of providing a stairway formed by at least one block of closed and solid material, each of said at least one block having a density of less than 500 kg / m3, and in that it comprises a step c) waterproof covering of at least the staircase by an impervious coating adapted to make the basin watertight.
Another alternative method is described in a method according to claim 10.

Ces méthodes permettent d'ériger plus rapidement et plus simplement un escalier de piscine à partir d'éléments légers et aisément manipulables.These methods make it possible to erect a swimming pool staircase faster and more simply from light and easily handled elements.

L'invention est définie par les revendications indépendantes. Les revendications dépendantes définissent des modes de réalisation préférés de l'invention.The invention is defined by the independent claims. The dependent claims define preferred embodiments of the invention.

Ainsi, lorsque le bloc de matière est creux et ouvert, c'est la masse volumique occupée par le matériau qu'il faut prendre en compte.The present invention relates to a swimming pool (1) comprising a pool. In the context of this invention, the term swimming pool also includes spa type baths or Jacuzzi. With reference to the figure 1 the pool basin (1) has a bottom (2). This bottom (2) may for example be concrete in the case of pools (1) having a fully concrete structure. At least one side wall (3) is present. Of course, several sidewalls may be present. This side wall (3) may for example be vertical and be a stack of concrete blocks, a wooden structure wall, a steel wall, a plastic wall, or even a concrete veil. A staircase (10) formed of at least one block of material (4) is present. This staircase (10) is separated from the pool, that is to say that the pool and the staircase (10) are independent of each other when the staircase is covered by the impermeable coating. Each of the blocks of material (4) has a density of less than 1000 kg / m 3 , preferably less than 500 kg / m 3 , and even more preferably less than 250 kg / m 3 . Preferably, each of the blocks of material (4) has a density of between 15 kg / m 3 and 500 kg / m 3 , even more preferably between 20 kg / m 3 and 250 kg / m 3 , and still more preferably between 30 kg / m 3 and 60 kg / m 3 . By density, it is necessary to understand the density of the material constituting the block of material. Thus, when the block of material is hollow and open, it is the density occupied by the material that must be taken into account.

L'au moins un bloc de matière (4) est fermé sur sa face supérieure (40), c'est-à-dire qu'il ne présente aucun trou tel qu'un trou pour couler un béton. Autrement dit, les blocs de matière (4) ne sont pas des blocs à bancher bétonnés. De façon préférentielle, le bloc de matière (4) est un bloc fermé, c'est-à-dire qu'aucune des faces du bloc de matière (4) ne présente de trou. De manière toujours plus préférentielle, le bloc de matière (4) est un bloc fermé et plein. Par bloc plein, il faut comprendre que le bloc de matière (4) ne comprend pas de cavité ou de méat, notamment destinés par exemple à recevoir un matériau exogène, tel que par exemple un béton.The at least one block of material (4) is closed on its face upper (40), that is to say it has no hole such as a hole for pouring a concrete. In other words, the blocks of material (4) are not concrete blocks. Preferably, the block of material (4) is a closed block, that is to say that none of the faces of the block of material (4) has a hole. In a still more preferred manner, the block of material (4) is a closed and solid block. By solid block, it should be understood that the block of material (4) does not comprise a cavity or meatus, in particular intended for example to receive an exogenous material, such as for example a concrete.

De manière préférentielle, le bloc de matière (4) est un bloc en polystyrène, en polyuréthane, en liège, en polychlorure de vinyle (PVC) recyclé ou non, ou en bois. De manière encore plus préférentielle, les blocs de matière (4) sont en polystyrène expansé ou en polystyrène extrudé.Preferably, the block of material (4) is a block of polystyrene, polyurethane, cork, polyvinyl chloride (PVC) recycled or not, or wood. Even more preferably, the material blocks (4) are expanded polystyrene or extruded polystyrene.

De préférence, les blocs de matériau présentent une résistance à la compression supérieure à 20 kPa à des conditions d'écrasement à 10%. De façon préférentielle, les blocs de matériau présentent une résistance à la compression supérieure à 60 kPa à des conditions d'écrasement à 10%, et de façon encore plus préférentielle, les blocs de matériau présentent une résistance à la compression supérieure à 150 kPa à des conditions d'écrasement à 10%. Cette résistance peut être mesurée selon la norme EN-826.Preferably, the blocks of material have a compressive strength greater than 20 kPa at 10% crushing conditions. Preferably, the blocks of material have a compressive strength greater than 60 kPa at 10% crushing conditions, and even more preferably, the blocks of material have a compressive strength greater than 150 kPa at crush conditions to 10%. This resistance can be measured according to the EN-826 standard.

L'au moins un bloc de matière (4) forme au moins une marche (10a) de l'escalier (10). Dans le cas où l'escalier (10) comporte plusieurs marches (10a) et ne comprend qu'un bloc de matière (4), un seul bloc de matière (4) forme plusieurs marches, tel qu'illustré à la fig. 1 . Alternativement, les marches (10a) de l'escalier (10) peuvent être formées par plusieurs blocs de matière (4) : chaque marche (10a) peut être formée par un seul bloc de matière (4a, 4b, 4c, 4d, 4e, 4f), comme illustré à la fig.2 , ou plusieurs ensembles de marches peuvent être formés par des blocs de matière distincts (4). Lorsqu'une pluralité de blocs de matière (4a, 4b, 4c, 4d, 4e, 4f) est présente, les blocs (4) peuvent présenter au moins une largeur et/ou une profondeur décroissante afin de pouvoir empiler les blocs pour former une ou plusieurs marches (10a) de l'escalier (10). De façon préférentielle, tous les blocs de matière (4) ont la même hauteur. Un escalier selon l'invention pouvant revêtir différentes formes (un trapèze, un triangle, un demi-cercle ou une forme libre), il n'y a pas de limites aux dimensions et à la forme que peuvent avoir les blocs de matière (4). De façon préférentielle, les blocs de matière (4) sont des parallélépipèdes, encore plus préférentiellement des parallélépipèdes rectangles. Alternativement, lorsque l'escalier (10) est dans un angle du bassin de la piscine, chacun des blocs de matière (4) peut être une partie d'un parallélépipède rectangle sectionné selon sa hauteur. Toujours alternativement, chacun des blocs de matière (4) peut présenter au moins une surface horizontale en forme de demi-cercle, ou une surface de forme libre.The at least one block of material (4) forms at least one step (10a) of the staircase (10). In the case where the staircase (10) has several steps (10a) and comprises only a block of material (4), a single block of material (4) forms several steps, as illustrated in FIG. Fig. 1 . Alternatively, the steps (10a) of the staircase (10) can be formed by several blocks of material (4): each step (10a) can be formed by a single block of material (4a, 4b, 4c, 4d, 4e , 4f), as shown in fig.2 , or more sets of steps may be formed by separate blocks of material (4). When a plurality of material blocks (4a, 4b, 4c, 4d, 4e, 4f) is present, the blocks (4) may have at least one decreasing width and / or depth in order to be able to stack the blocks to form a or several steps (10a) of the staircase (10). Preferably, all blocks of material (4) have the same height. Since a staircase according to the invention can take different forms (a trapezium, a triangle, a semi-circle or a free form), there are no limits to the dimensions and the shape that the blocks of material can have (4 ). Preferably, the blocks of material (4) are parallelepipeds, even more preferably rectangular parallelepipeds. Alternatively, when the staircase (10) is in an angle of the pool of the pool, each of the blocks of material (4) may be part of a rectangular parallelepiped sectioned according to its height. Still alternately, each of the blocks of material (4) may have at least one horizontal surface in the form of a semicircle, or a free-form surface.

Lorsque qu'une pluralité de blocs de matière (4) forment l'escalier (10), il est préférable de solidariser les blocs de matière (4) entre eux, par exemple en collant la surface inférieure d'un premier bloc de matière avec la surface supérieure (40) d'un second bloc de matière sur lequel repose le premier bloc de matière. Alternativement, les blocs peuvent comporter des organes d'emboitement avec un bloc voisin. Les organes d'emboitement peuvent par exemple être présents sur une face supérieure (40) et/ou sur une face inférieure. Toujours à titre d'exemple, ces organes d'emboitement peuvent comporter une languette sur une surface d'un bloc et une rainure sur une surface d'un bloc. Il s'entend que ces organes sont aptes à coopérer entre eux, et que ces organes peuvent prendre différentes formes et positions sur une surface d'un bloc de matière.When a plurality of material blocks (4) form the stair (10), it is preferable to join the blocks of material (4) together, for example by gluing the lower surface of a first block of material with the upper surface (40) of a second block of material on which the first block of material rests. Alternatively, the blocks may comprise interlocking members with a neighboring block. The interlocking members may for example be present on an upper face (40) and / or on a lower face. Still as an example, these interlocking members may comprise a tongue on a surface of a block and a groove on a surface of a block. It is understood that these organs are able to cooperate with each other, and that these organs can take different forms and positions on a surface of a block of material.

L'escalier (10) comprend une surface inférieure (41). Lorsque l'escalier (10) comporte un seul bloc de matière (4), la surface inférieure (41) de l'escalier (10) correspond à la surface inférieure du bloc de matière (4). Lorsqu'une pluralité de blocs de matière (4a, 4b, 4c, 4d, 4e, 4f) est présent, la surface inférieure (41) de l'escalier (10) correspond à la surface inférieure du bloc de matière (4a) le moins élevé de l'escalier (10) et formant généralement au moins une première marche de l'escalier (10), généralement le bloc (4a) présentant une plus grande largeur et/ou une plus grande profondeur, en fonction de l'architecture de l'escalier (10).The staircase (10) comprises a lower surface (41). When the staircase (10) comprises a single block of material (4), the lower surface (41) of the staircase (10) corresponds to the lower surface of the block of material (4). When a plurality of blocks of material (4a, 4b, 4c, 4d, 4e, 4f) is present, the lower surface (41) of the staircase (10) corresponds to the lower surface of the block of material (4a) the lower of the staircase (10) and generally forming at least a first step of the staircase (10), generally the block (4a) having a greater width and / or a greater depth, depending on the architecture of the stairs (10).

La surface inférieure (41) de l'escalier (10) repose sur le fond (2) de la piscine. Par exemple, lorsque l'escalier (10) ne comporte qu'un seul bloc de matière (4), la surface inférieure du bloc de matière (4) et la surface du fond (2) sont en contact. Lorsque une pluralité de blocs de matière (4a, 4b, 4c, 4d, 4e, 4f) composent l'escalier (10), la surface inférieure du bloc de matière (4a) qui a la plus grande largeur et/ou qui a la plus grande profondeur est en contact avec le fond (2) de la piscine (1). Préférentiellement, la surface inférieure (41) de l'escalier (10) est fixée sur le fond (2), par exemple grâce à une colle de type polyuréthane. Lorsque plusieurs blocs de matière (4) sont présents, la surface inférieure du bloc le plus inférieur de l'escalier peut être collée sur le fond de la piscine, par exemple au moyen d'une colle de type polyuréthane.The lower surface (41) of the staircase (10) rests on the bottom (2) of the swimming pool. For example, when the staircase (10) has only one block of material (4), the lower surface of the block of material (4) and the bottom surface (2) are in contact. When a plurality of material blocks (4a, 4b, 4c, 4d, 4e, 4f) compose the staircase (10), the lower surface of the block of material (4a) which has the greatest width and / or which has the greater depth is in contact with the bottom (2) of the pool (1). Preferably, the lower surface (41) of the staircase (10) is fixed on the bottom (2), for example by means of a polyurethane type glue. When several blocks of material (4) are present, the lower surface of the lower block of the staircase can be glued to the bottom of the pool, for example by means of a polyurethane type glue.

Le revêtement imperméable (5) recouvre imperméablement au moins l'escalier (10), de façon à l'isoler hydriquement du milieu externe en formant une enveloppe continue et étanche. Ainsi, les blocs de matière (4) sont hors eau lorsque le bassin de la piscine (1) est rempli d'eau. Le revêtement imperméable (5) peut par exemple être une membrane étanche, communément appelée « liner », en matière plastique, par exemple une membrane en PVC. Ce liner peut être collé sur toute surface apparente de l'escalier (10). Alternativement, le revêtement imperméable (5) peut être un matériau solide carrelé, comme par exemple une céramique décorative, en terre cuite, en faïence ou en grès. Il s'entend que dans le cas d'un matériau carrelé, la jointure entre les différentes pièces est réalisée grâce à un joint étanche. De façon préférentielle, un joint d'étanchéité peut relier le revêtement imperméable (5) au fond (2) et/ou à une paroi latérale (3) du bassin de la piscine (1). Un enduit d'étanchéité peut également recouvrir intégralement le revêtement imperméable, notamment lorsque ce dernier est un matériau solide carrelé.The waterproof coating (5) impermeably covers at least the staircase (10), so as to isolate it hydraulically from the external environment forming a continuous and sealed envelope. Thus, the blocks of material (4) are out of water when the basin of the pool (1) is filled with water. The impermeable coating (5) may for example be a waterproof membrane, commonly called "liner", made of plastic, for example a PVC membrane. This liner can be glued on any apparent surface of the staircase (10). Alternatively, the impermeable coating (5) may be a solid tiled material, such as a decorative ceramic, terracotta, earthenware or sandstone. It is understood that in the case of a tiled material, the joint between the different parts is achieved through a seal. Preferably, a seal may connect the impermeable coating (5) to the bottom (2) and / or a side wall (3) of the pool (1). A sealant may also completely cover the impermeable coating, especially when the latter is a tiled solid material.

Selon un mode de réalisation préféré de l'invention, l'escalier (10) est placé contre au moins une paroi latérale (3). A cette fin, une surface latérale (42) d'au moins un bloc de matière (4) est jointive d'une surface de la paroi latérale (3) de la piscine (1). Selon un mode de réalisation préféré, la surface latérale (42) d'au moins un bloc de matière (4) est fixée à la surface de la paroi latérale (3), par exemple au moyen d'une colle, par exemple une colle de type polyuréthane. Lorsqu'une pluralité de blocs de matière (4a, 4b, 4c, 4d, 4e, 4f) est présente, une partie ou tous les blocs de matière (4a, 4b, 4c, 4d, 4e, 4f) peuvent ainsi être jointifs à la paroi latérale (3) par une de leurs surfaces latérales (42). Il est possible, afin d'améliorer l'isolation de l'escalier (10), de recouvrir imperméablement le fond (2) et l'au moins une paroi latérale (3) en prolongeant le revêtement imperméable (5) recouvrant l'escalier (10), de sorte que lorsque le bassin de la piscine (1) est rempli d'eau, cette dernière ne soit pas directement en contact avec le fond (2) de la piscine (1) et avec les parois latérales (3). Ce mode de réalisation est illustré à la fig. 3 . According to a preferred embodiment of the invention, the staircase (10) is placed against at least one side wall (3). To this end, a lateral surface (42) of at least one block of material (4) is joined to a surface of the side wall (3) of the pool (1). According to a preferred embodiment, the lateral surface (42) of at least one block of material (4) is fixed to the surface of the side wall (3), for example by means of an adhesive, for example a polyurethane type glue. When a plurality of material blocks (4a, 4b, 4c, 4d, 4e, 4f) is present, some or all of the material blocks (4a, 4b, 4c, 4d, 4e, 4f) can thus be joined to the side wall (3) by one of their lateral surfaces (42). It is possible, in order to improve the insulation of the staircase (10), to impermeably cover the bottom (2) and the at least one side wall (3) by extending the impervious covering (5) covering the staircase (10), so that when the pool basin (1) is filled with water, the latter is not directly in contact with the bottom (2) of the pool (1) and with the side walls (3) . This embodiment is illustrated in Fig. 3 .

De manière préférentielle, la surface inférieure (41) de l'escalier (10) et le fond (2) du bassin de la piscine (1) sont complémentaires afin que la surface de l'au moins une marche (10a) de l'escalier (10) soit substantiellement horizontale. A titre d'exemple, si le fond (2) du bassin de la piscine (1) est une surface plane en pente, alors la surface inférieure (41) du bloc de matière (4 ou 4a) en contact avec le fond (2) de la piscine (1) est également une surface plane en pente selon un angle similaire à l'angle de la pente du fond (2) de la piscine (1), mais la surface de la première marche (10a) est orientée de façon à ce qu'elle soit substantiellement horizontale. Autrement dit, une surface supérieure d'une première marche de l'escalier (10) et la surface inférieure (41) reposant sur le fond (2) sont agencées de manière à ce que ladite surface supérieure de la première marche soit substantiellement horizontale.Preferably, the lower surface (41) of the staircase (10) and the bottom (2) of the pool basin (1) are complementary so that the surface of the at least one step (10a) of the staircase (10) is substantially horizontal. For example, if the bottom (2) of the swimming pool (1) is a flat sloping surface, then the lower surface (41) of the block of material (4 or 4a) in contact with the bottom (2) ) of the pool (1) is also a flat surface sloping at an angle similar to the angle of the slope of the bottom (2) of the pool (1), but the surface of the first step (10a) is oriented from so that it is substantially horizontal. In other words, an upper surface of a first step of the staircase (10) and the lower surface (41) resting on the bottom (2) are arranged so that said upper surface of the first step is substantially horizontal.

Selon un mode de réalisation particulier de l'invention, le nez de chaque marche (10a) de l'escalier (10) est recouvert d'un profilé en « L ». Ce profilé peut être dans une matière solide et résistante, tel qu'une cornière métallique, par exemple en acier, ou une tôle colaminée, par exemple une fine tôle en aluminium protégée contre la corrosion et recouverte par une membrane synthétique ou un élastomère, ou une cornière plastique, par exemple en polyester. Lorsque le nez de chaque marche (10a) est recouvert d'un profilé, le revêtement imperméable (5) est situé au dessus de ce profilé. La présence de ce profilé permet d'améliorer la résistance du nez des marches, augmentant ainsi la robustesse générale de l'escalier (10).According to a particular embodiment of the invention, the nose of each step (10a) of the staircase (10) is covered with an "L" profile. This profile may be in a strong and resistant material, such as a metal angle, for example steel, or a rolled sheet, for example a thin aluminum sheet protected from corrosion and covered by a synthetic membrane or an elastomer, or a plastic angle, for example polyester. When the nose of each step (10a) is covered with a profile, the impervious coating (5) is located above this profile. The presence of this profile makes it possible to improve the resistance of the nose of the steps, thus increasing the overall robustness of the staircase (10).

  1. a) fourniture d'une piscine (1) comprenant un bassin, ledit bassin comprenant un fond (2) et au moins une paroi latérale (3), d'un escalier (10) formé par au moins un bloc de matière (4) fermé sur sa face supérieure,chacun desdits au moins un bloc (4) ayant une masse volumique inférieure à 1 000 kg/m3, et d'un revêtement imperméable (5) adapté pour rendre le bassin étanche,
  2. b) pose de l'escalier (10) sur le fond (2) de la piscine (1),

  3. c) impervious covering of the staircase (10) by the impermeable covering (5).

  • a') fourniture d'une piscine comprenant un fond (2) et au moins une paroi latérale (3), d'une pluralité de blocs de matière (4) fermés sur leur face supérieure, chacun des blocs (4) ayant une masse volumique inférieure à 1 000 kg/m3 et d'un revêtement imperméable (5) adapté pour rendre le bassin étanche,
  • b') construction d'un escalier (10) à partir de la pluralité de blocs (4) par empilement des dits blocs (4), au moins un bloc (4) étant posé sur le fond (2) de la piscine (1),
  • c') recouvrement imperméable de l'escalier (10) par le revêtement imperméable (5).
According to this method, the staircase (10) provided is already mounted. Alternatively, the method may include a step of mounting the staircase (10). For this purpose, the method comprises the steps of:
  • a ') providing a swimming pool comprising a bottom (2) and at least one side wall (3), a plurality of blocks of material (4) closed on their upper face, each of the blocks (4) having a mass volume less than 1 000 kg / m 3 and an impervious covering (5) adapted to make the basin watertight,
  • b ') constructing a staircase (10) from the plurality of blocks (4) by stacking said blocks (4), at least one block (4) being placed on the bottom (2) of the pool (1). )
  • c ') impervious covering of the staircase (10) by the waterproof coating (5).

L'au moins un bloc de matière (4) constituant l'escalier (10) ou l'au moins un bloc de matière (4) fourni pour construire un escalier (10) est un bloc de matière (4) pouvant avoir l'une quelconque des caractéristiques exposées précédemment.The at least one block of material (4) constituting the staircase (10) or the at least one block of material (4) provided for constructing a staircase (10) is a block of material (4) which may have the any of the features set forth above.

La surface inférieure (41) de l'escalier (10) peut être collée sur le fond (2) de la piscine (1), avant l'étape de recouvrement par le revêtement imperméable (5). Alternativement ou supplémentairement, une surface latérale (42) d'au moins un bloc de matière (4) peut être collée à une surface d'une paroi latérale (3) de la piscine (1), lorsque l'escalier (10) est placé ou monté contre une paroi latérale (3) de la piscine (1). De façon toujours alternative ou complémentaire, lorsqu'une pluralité de blocs de matière (4a, 4b, 4c, 4d, 4e, 4f) est montée en escalier (10), les blocs (4a, 4b, 4c, 4d, 4e, 4f) constituant l'escalier (10) peuvent être collés entre eux, ou, toujours complémentairement ou alternativement, être agencés entre eux grâce à des organes d'emboitement.The lower surface (41) of the staircase (10) can be glued to the bottom (2) of the pool (1), before the covering step by the impermeable coating (5). Alternatively or additionally, a lateral surface (42) at least one block of material (4) can be glued to a surface of a side wall (3) of the pool (1), when the stair (10) is placed or mounted against a side wall (3) the pool (1). In an always alternative or complementary manner, when a plurality of material blocks (4a, 4b, 4c, 4d, 4e, 4f) are mounted in steps (10), the blocks (4a, 4b, 4c, 4d, 4e, 4f ) constituting the staircase (10) can be glued together, or, always complementarily or alternatively, be arranged between them by means of interlocking members.

Une fois l'escalier (10) posé ou monté sur le fond (2) de la piscine (1), l'étape de recouvrement de l'escalier (10) par le revêtement imperméable (5) peut être complétée d'une étape de recouvrement imperméable du fond (2) de la piscine (1) et des parois latérales (3) de la piscine (1) par le revêtement imperméable (5) recouvrant imperméablement l'escalier.Once the staircase (10) is installed or mounted on the bottom (2) of the pool (1), the step of covering the staircase (10) with the impermeable covering (5) can be completed by a step impermeable covering of the bottom (2) of the pool (1) and the side walls (3) of the pool (1) by the impermeable coating (5) imperviously covering the staircase.

This step can take place before the step of covering the stair (10) by the impermeable coating (5).
