Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne un escalier de type balancé préfabriqué en béton. Il est constitué par l'assemblage de différents éléments préfabriqués, et en l'espèce les marches et les éléments d'un fût central, assemblés sur site.The present invention relates to a prefabricated balanced type staircase made of concrete. It is constituted by the assembly of different prefabricated elements, and in this case the steps and the elements of a central shaft, assembled on site.

Un escalier de type balancé préfabriqué en béton est connu du CH 674539 .A prefabricated balanced concrete staircase is known from CH 674539 .

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE TECHNIQUE

Les escaliers préfabriqués sont aujourd'hui d'un usage largement répandu, dans la mesure où ils permettent tout d'abord de réaliser un gain substantiel de temps, notamment lors de la pause de l'escalier sur le chantier, et d'autre part un gain en termes de prix de revient.Prefabricated staircases are nowadays widely used, insofar as they allow first of all to realize a substantial gain of time, in particular during the pause of the staircase on the building site, and on the other hand a gain in terms of cost price.

Parmi les différents types d'escalier, on connaît les escaliers monoblocs balancé à mur porteur, dont les marches rayonnent autour dudit mur. Le poids conséquent de ce type d'escalier, typiquement 2.500 à 3.500 kg nécessite pour leur mise en place des moyens de levage adaptés très difficile à rencontrer, notamment sur les chantiers de maisons individuelles.Among the various types of staircase, there are known one-piece staircases balanced with load-bearing wall, whose steps radiate around said wall. The heavy weight of this type of staircase, typically 2,500 to 3,500 kg requires for their implementation adapted lifting means very difficult to meet, especially on individual housing projects.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'objet de l'invention est de simplifier la mise en place de ce type d'escalier outre sa réalisation.The object of the invention is to simplify the implementation of this type of staircase in addition to its implementation.

A cet effet, il propose un escalier préfabriqué en béton de type balancé, constitué par l'assemblage de marches préfabriquées convergentes au niveau d'un mur porteur central.For this purpose, it proposes a prefabricated staircase of balanced type of concrete, constituted by the assembly of prefabricated steps converging at a central bearing wall.

Selon l'invention :

  • chaque marche est pourvue au niveau de sa zone de convergence en direction du mur porteur central d'une saillie supérieure prolongeant le plateau de marche et une partie de la contremarche ;
  • le mur central est pourvu d'une encoche ménagée au sein de la paroi latérale le définissant, au niveau de laquelle vient prendre appui la saillie émanant de ladite marche correspondante, ladite encoche étant décalée d'un élément unitaire à l'élément unitaire supérieur.
According to the invention:
  • each step is provided at its convergence zone towards the central bearing wall with an upper projection extending the step plate and a portion of the riser;
  • the central wall is provided with a notch formed in the defining side wall, at which the protrusion emanating from said corresponding step is supported, said notch being offset from a unitary element to the upper unitary element.

En d'autres termes, préalablement à la réalisation de l'escalier proprement dit, les éléments unitaires du mur central ne sont pas solidarisés aux marches et peuvent donc être montés simultanément avec les marches au fur et à mesure de la réalisation de l'escalier, étant souligné que l'on procède a un coulage du béton dans le mur central lorsqu'un nombre de marches déterminé a été posé.In other words, prior to the completion of the staircase itself, the unitary elements of the central wall are not secured to the steps and can therefore be mounted simultaneously with the steps as and when the staircase , being stressed that concrete is poured into the central wall when a certain number of steps has been laid.

Selon l'invention, chacune des marches est avantageusement munie d'un ferraillage pour permettre son clavetage au niveau du mur central, préalablement, bien évidemment, au coulage du béton au sein de celui-ci.According to the invention, each of the steps is advantageously provided with a reinforcement to enable it to be keyed at the level of the central wall, beforehand, obviously, to the pouring of concrete within it.

En outre, chaque marche présente au niveau du plateau de marche, un évidement ménagé du côté opposé à sa zone de convergence en direction du mur central porteur, et d'une saillie ou butée s'étendant au niveau de la contremarche dont elle est munie, ledit évidement d'une marche étant destiné à coopérer avec le prolongement ou saillie de la marche supérieure. Les marches travaillent ainsi en console, avec comme point d'ancrage le mur central. Selon l'invention, on rend solidaire chacune des marches avec le mur central porteur par le coulage du béton afin de reprendre en flexion les efforts de celles-ci.In addition, each step has at the level of the walking plate, a recess formed on the opposite side to its convergence zone towards the central carrier wall, and a protrusion or abutment extending at the riser with which it is equipped. said recess of a step being adapted to cooperate with the extension or projection of the upper step. The steps work as a console, with the central wall as an anchor. According to the invention, each of the steps is made integral with the central wall carrier by pouring concrete to resume flexion efforts of these.

Selon une autre caractéristique de l'invention, le mur porteur reçoit au moins deux niveaux d'armature porteuse, destinées à être solidarisées l'une à l'autre par le coulage du béton.According to another characteristic of the invention, the load-bearing wall receives at least two levels of carrying reinforcement, intended to be secured to one another by the pouring of the concrete.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On a donc représenté en relation avec la figure 1 l'escalier balancé conforme à l'invention.So we have shown in relation to the figure 1 the balanced staircase according to the invention.

Celui-ci est constitué d'un fût ou mur central 1 de section transversale, non pas circulaire, mais allongée, constitué de la superposition d'éléments unitaires 2, ayant tous la même forme, à l'exception d'une encoche davantage décrite en relation avec la figure 2.It consists of a shaft or central wall 1 of cross section, not circular, but elongated, consisting of the superposition of unit elements 2 , all having the same shape, except for a notch more described in relation to the figure 2 .

Il comporte également une succession de marches 3 convergeant toutes au niveau du mur central 1 et venant prendre appui au niveau de celui-ci.It also comprises a succession of steps 3 converging all at the central wall 1 and coming to bear on the level thereof.

Comme on peut le voir sur la figure 2, chaque élément unitaire 2 est creux, et est défini par une paroi latérale 4 s'étendant sur toute sa hauteur. Il convient à cet égard de préciser que la hauteur de chacun des éléments unitaires 2 correspond à la hauteur au sens normalisé du terme de la marche correspondante 3.As can be seen on the figure 2 each unit element 2 is hollow, and is defined by a side wall 4 extending over its entire height. It should be noted in this regard that the height of each of the unit elements 2 corresponds to the height in the standardized sense of the term of the corresponding step 3 .

Ladite paroi latérale 4 définissant les éléments unitaires 2 est pourvue d'une encoche 5, décalée d'un élément unitaire 2 par rapport à l'élément unitaire adjacent et en l'espèce supérieur.Said lateral wall 4 defining the unitary elements 2 is provided with a notch 5 , shifted by a unit element 2 with respect to the adjacent unitary element and in the upper case.

Cette encoche 5 est destinée à coopérer avec une saillie ou prolongement supérieur 6 émanant de la marche 3 avec laquelle il est destiné à coopérer, ladite saillie prolongeant exactement le plateau de la marche 3 ainsi qu'on peut bien l'observer sur la figure 2, outre une partie de la contremarche.This notch 5 is intended to cooperate with a protrusion or upper extension 6 emanating from the step 3 with which it is intended to cooperate, said projection extending exactly the tray of the step 3 as can be observed on the figure 2 , besides a part of the riser.

En d'autres termes, la marche 3 vient prendre appui au niveau de cette encoche par le biais de ce prolongement 6, ladite encoche présentant une découpe correspondant à la forme de la saillie 6.In other words, the step 3 comes to bear at this notch via this extension 6 , said notch having a cut corresponding to the shape of the projection 6 .

En outre, du côté opposé a cette saillie 6, la marche présente d'une part un évidement 7, au niveau de la partie supérieure de la marche proprement dite et, destinée à faire fonction de butée de calage. Ladite marche présente également, au niveau de sa contremarche une saillie 8, à l'exception de la première marche, c'est-à-dire celle destinée à venir être positionnée sur la dalle recevant l'escalier. Cette saillie 8 est destinée à venir coopérer avec la butée de calage 7 de la marche inférieure, et ce dans un souci de favoriser la stabilité de l'ensemble. Elle est en outre de forme complémentaire à l'évidement 7 pour optimiser cette fonction de stabilité et pour reprendre en flexion les efforts de celle-ci.In addition, on the opposite side to this projection 6 , the step has on the one hand a recess 7, at the upper part of the step itself and intended to act as a stop abutment. Said step also has, at its riser projection 8 , with the exception of the first step, that is to say that intended to be positioned on the slab receiving the staircase. This projection 8 is intended to cooperate with the abutment stop 7 of the lower step, and this in order to promote the stability of the assembly. It is also of complementary shape to the recess 7 to optimize this stability function and to bend the efforts of the latter.

De plus, chacune des marches présente un ferraillage 9, émanant de son plan supérieur ou plateau de marche, destiné à venir être ligaturé ou claveté au niveau d'un treillis métallique ou de barres ou tiges métalliques 10, positionné(es) au niveau de la zone creuse du fût central. Cette ligature est réalisée préalablement au coulage du béton au sein dudit creux et ce, afin d'assurer la stabilité de la structure.In addition, each of the steps has a reinforcement 9 , emanating from its upper plane or walking plate, intended to be ligated or keyed at a wire mesh or metal bars or rods 10 , positioned at the level of the hollow area of the central shaft. This ligation is performed prior to casting the concrete within said hollow and to ensure the stability of the structure.

On a représenté en relation avec la figure 4 le principe de l'assemblage de l'escalier conforme à l'invention.We have shown in relation to the figure 4 the principle of assembling the staircase according to the invention.

Ainsi en figure 4A, une dalle plane 11 en béton est préparée, au sein de laquelle sont réalisé un certain nombre de réservations pratiquées par perçage 12 aux fins de permettre le scellement des barres ou tiges métallique 10 constitutives d'une demi cage inférieure d'armature porteuse du mur 1.So in Figure 4A a concrete flat slab 11 is prepared, within which are made a number of reservations made by drilling 12 for the purpose of allowing the sealing of bars or metal rods 10 constituting a half-cage lower frame carrying the wall 1 .

En figure 4B est d'ailleurs représentée la mise en place de ladite demi-cage inférieure d'armature 10 avec son scellement sur la dalle 11.In Figure 4B is also shown the establishment of said half frame lower cage 10 with its seal on the slab 11 .

On procède alors (figure 4C) au positionnement d'un premier élément 2 constitutif du mur par enfilage le long de ladite demi cage inférieure 10. Sa solidarisation à la dalle est réalisée par exemple au moyen d'un lit de mortier, préalablement déposé sur ladite dalle.We proceed then ( figure 4C ) the positioning of a first element 2 constituting the wall by threading along said lower half-cage 10 . Its fastening to the slab is carried out for example by means of a bed of mortar, previously deposited on said slab.

Puis, lors de l'étape suivante, illustrée au sein de la figure 4D, on procède à la mise en place de la première marche 3. La saillie 6 de celle-ci vient se positionner au niveau de l'encoche 5 dont est pourvu le premier élément du mur. On assure le calage temporaire de ladite marche au moyen de cales positionnées au niveau de sa zone postérieure qu'on peut bien l'observer.Then, in the next step, illustrated in the figure 4D , we proceed to the implementation of the first step 3 . The projection 6 thereof is positioned at the notch 5 which is provided with the first wall element. Temporary wedging of said step is ensured by means of wedges positioned at its posterior zone which can be observed.

Par ailleurs, on procède à la ligature ou au clavetage du ferraillage 9 de ladite marche au niveau des barres ou tiges métalliques 10.In addition, the reinforcement 9 of said step is lashed or keyed at the level of the metal bars or rods 10 .

On procède alors au positionnement d'un joint sur la partie supérieure de la paroi latérale 4 de l'élément unitaire du fût mis en place lors de l'étape de la figure 4C, mais également au niveau du fond de plateau de marche pour permettre d'accueillir (figure 4E) l'élément unitaire immédiatement supérieur de mur, toujours introduit par coulissement le long des demi barres métalliques constituant la cage.We then proceed to the positioning of a seal on the upper part of the side wall 4 of the unitary element of the drum set up during the step of the figure 4C , but also at the bottom of the walking board to accommodate ( figure 4E ) the next unit wall element, always introduced by sliding along the half metal bars constituting the cage.

Ce joint aide à la tenue des éléments entre eux et contribue à créer le monolithisme nécessaire pour la tenue structurelle de ces éléments.This joint helps to hold the elements together and helps to create the monolithism necessary for the structural holding of these elements.

Puis, (figure 4F), on procède à la mise en place de la marche supérieure correspondante. Celle-ci vient prendre appui par sa saillie 6 au niveau de l'encoche 5 dont est pourvu le second élément unitaire de fût, ladite encoche étant décalée par rapport à celle du premier élément unitaire de fût. Cette marche est également calée de manière temporaire par une cale de hauteur appropriée, venant se positionner sous le plateau de marche.Then, ( figure 4F ), the corresponding upper step is set up. It comes to bear by its projection 6 at the notch 5 which is provided with the second unit drum member, said notch being offset from that of the first unit drum member. This step is also wedged temporarily by a wedge of appropriate height, being positioned under the walking tray.

On a représenté en relation avec les figures 4G et 4H, la mise en place du troisième élément de fût et de la troisième marche, de manière tout à fait analogue aux marches inférieures.We have shown in relation with the Figures 4G and 4H , the establishment of the third barrel element and the third step, in a manner quite similar to the lower steps.

On procède ainsi au montage des différentes marches constitutives de l'escalier jusqu'à la terminaison de celui-ci de manière identique, les encoches des éléments de fût successifs étant décalées l'une part rapport à l'autre au fur et à mesure de la progression de l'escalier.The steps constituting the stairway are thus assembled to the end of the staircase in identical manner, the notches of the successive casing elements being offset relative to one another as and when the the progression of the stairs.

Lorsqu'environ un nombre déterminé de marches a été posé, par exemple sept, on procède au coulage du béton à l'intérieur du mur alors constitué, puis après séchage, on poursuit la progression de l'escalier.When about a certain number of steps has been set, for example seven, the concrete is poured inside the wall then formed, then after drying, the progression of the staircase is continued.

Lorsque le béton a séché, on enlève les cales assurant le positionnement des marches successives.When the concrete has dried, remove the wedges ensuring the positioning of the successive steps.

On conçoit de fait l'extrême simplicité de réalisation de l'escalier conforme à l'invention puisqu'en premier lieu, on utilise des éléments unitaires, qu'il s'agisse des éléments du fût ou de marches, préfabriqués et manuportables, s'affranchissant donc de tout outil de levage.It is conceived in fact the extreme simplicity of realization of the staircase according to the invention since in the first place, it uses unitary elements, whether the elements of the drum or steps, prefabricated and manuportable, s thus freeing from any lifting tool.

En outre, en raison des encoches ménagées au niveau des éléments unitaires du fût outre des butées de calage des marches, le positionnement des marches respectivement les unes par rapport aux autres s'en trouve grandement facilité.In addition, because of the notches provided at the level of the unitary elements of the barrel in addition to the step stops of the steps, the positioning of the steps respectively relative to each other is greatly facilitated.

L'adaptation de cet escalier aux dimensions du chantier peut également être facilement réalisée par simple modification des moules constitutifs des éléments unitaires de fût d'une part et des marches d'autre part.The adaptation of this staircase to the dimensions of the site can also be easily achieved by simply changing the molds constituting the unitary elements of the barrel on the one hand and steps on the other.
