Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne un procédé pour la réalisation, sur site ou en usine, d'escaliers en béton et également pour la réalisation de plateaux de marche en béton, à vocation à être positionnés sur un limon installé sur un chantier.The invention relates to a method for the production, on site or in the factory, of concrete stairs and also for the production of concrete walking platforms, intended to be positioned on a stringer installed on a site.

Elle vise également les plateaux de marche résultant de ce procédé, ainsi que les escaliers résultant d'un tel procédé.It also relates to the walking platforms resulting from this process, as well as the stairs resulting from such a process.

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE ART

La réalisation d'escalier en béton est aujourd'hui d'un usage largement répandu. Qu'il soit réalisé sur site (sur chantier) ou en usine, il passe traditionnellement par le moulage de l'intégralité de l'escalier ou de portions d'escalier, permettant d'aboutir à l'escalier proprement dit ou aux portions d'escalier, aptes à être positionnés sur site.Concrete staircase building is widely used today. Whether it is carried out on site (on site) or in the factory, it traditionally involves molding the entire staircase or portions of the staircase, leading to the staircase itself or to the portions of 'staircase, suitable for being positioned on site.

On connaît également des escaliers du type préfabriqué, également réalisés en béton, constitués d'éléments modulaires, aptes à favoriser leur déplacement sur site et leur montage. Ces escaliers comportent typiquement un limon sur lequel sont rapportés et fixés des éléments ou plateaux de marche, réalisés en béton, préalablement fabriqués par moulage.There are also known stairs of the prefabricated type, also made of concrete, consisting of modular elements, capable of promoting their movement on site and their assembly. These stairs typically include a stringer on which are attached and fixed elements or walking platforms, made of concrete, previously manufactured by molding.

Quel que soit le mode de réalisation de ces escaliers, il est requis pour un certain nombre d'applications la présence sur les plateaux de marche d'éléments antidérapants, notamment lorsque les escaliers ont vocation à être soumis aux intempéries donc à l'extérieur des bâtiments, afin d'éviter toute glissade des emprunteurs de ces escaliers.Whatever the embodiment of these staircases, it is required for a certain number of applications the presence on the walking platforms of non-slip elements, in particular when the stairs are intended to be subjected to weathering therefore outside the buildings, in order to avoid any slip by the borrowers of these stairs.

Ces éléments antidérapants sont le plus souvent constitués de stries linéaires réalisées à même le béton sur la surface supérieure du plateau de marche considéré, typiquement à l'aide d'une rainureuse. Outre la poussière importante que génère la réalisation de ces stries et, en outre, le manque de rectilinéarité, il est assez fréquent que lors de la réalisation du chantier de l'immeuble considéré, ces stries sont bouchées par les poussières du chantier, acheminées à ce niveau par les ouvriers et autres intervenants sur ledit chantier. Ce faisant, une fois bouchées, les stries en question ne remplissent plus leur fonction antidérapante.These non-slip elements are most often made up of linear ridges made directly from the concrete on the upper surface of the step plate in question, typically using a groover. Besides the significant dust generated by the realization of these streaks and, moreover, the lack of rectilinearity, it is quite common that during the completion of the construction site of the building considered, these streaks are clogged with dust from the site, transported to this level by workers and other workers on said site. In doing so, once plugged, the streaks in question no longer fulfill their non-slip function.

On connaît également la mise en œuvre d'inserts rapportés sur les plateaux de marche en question et fixés à demeure sur ladite surface. Si, lorsque les escaliers munis de tels inserts sont localisés à l'intérieur du bâtiment, on dispose d'une certaine pérennité de la fonction antidérapante ainsi générée. En revanche, ces inserts ne résistent pas très longtemps lorsqu'ils sont soumis aux intempéries extérieures, affectant là encore leur fonction antidérapante.We also know the implementation of inserts reported on the treads in question and permanently fixed to said surface. If, when the stairs fitted with such inserts are located inside the building, there is a certain durability of the non-slip function thus generated. On the other hand, these inserts do not resist very long when they are subjected to external weather conditions, again affecting their non-slip function.

Au demeurant, leur fixation impose une étape supplémentaire lors de la réalisation de l'escalier.Incidentally, fixing them requires an additional step when making the stairs.

L'objet de l'invention vise à pallier ces inconvénients et à proposer une solution alternative, à la fois simple à mettre en œuvre, tout particulièrement lors de la réalisation de chantiers.The object of the invention aims to overcome these drawbacks and to propose an alternative solution, which is both simple to implement, especially when carrying out construction sites.

EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention vise donc un procédé pour réaliser un escalier en béton dont les plateaux de marche sont munis de moyens antidérapants et mettant en œuvre le moulage de l'escalier lui-même ou le moulage des plateaux de marche de manière individualisée mis en œuvre dans lesdits escaliers.The invention therefore relates to a method for producing a concrete staircase whose walking platforms are provided with non-slip means and implementing the molding of the staircase itself or the molding of the walking platforms individually implemented in said stairs.

Selon l'invention, on munit le moule en question, au voisinage de la localisation du nez de marche des plateaux de marche, d'une bande PVC pourvue de stries longitudinales, lesdites stries en saillie étant orientées en direction de l'intérieur du moule.According to the invention, the mold in question is provided, in the vicinity of the location of the stair nosing of the walking platforms, with a PVC strip provided with longitudinal ridges, said projecting ridges being oriented towards the interior of the mold. .

En d'autres termes, l'invention consiste, préalablement au moulage de l'escalier proprement dit, ou des plateaux de marche proprement dits, à munir le moule correspondant d'une bande PVC munie de stries en saillie, destinée après démoulage à demeurer sur la face supérieure des plateaux de marche pendant une durée choisie par le concepteur, pour ensuite être escamotée ou retirée, ladite bande PVC définissant sur ladite face supérieure des plateaux de marche, et typiquement au voisinage du nez de marche, de rainures ou gorges longitudinales aptes à générer l'effet antidérapant recherché.In other words, the invention consists, prior to the molding of the staircase proper, or of the walking platforms proper, in providing the corresponding mold with a PVC strip provided with projecting ridges, intended after demolding to remain on the upper face of the walking platforms for a period chosen by the designer, to then be retracted or removed, said PVC strip defining on said upper face of the walking platforms, and typically in the vicinity of the stair nosing, of longitudinal grooves or grooves able to generate the desired non-slip effect.

Selon l'invention, ces stries sont orientées parallèlement à la direction principale du ou des plateaux de marche et typiquement perpendiculairement à la direction principale du limon ou de l'escalier.According to the invention, these streaks are oriented parallel to the main direction of the walking platform (s) and typically perpendicular to the main direction of the stringer or staircase.

Typiquement ces stries sont au nombre de trois, ce nombre n'étant cependant nullement limitatif.Typically these streaks are three in number, this number however being in no way limiting.

Selon l'invention, cette bande PVC est fixée au fond du moule au moyen d'un adhésif double face et à l'aide d'une règle gabarit, afin d'assurer un positionnement précis et reproductible desdites bandes PVC, et donc corollairement des moyens anti-dérapants tout au long de l'escalier.According to the invention, this PVC strip is fixed to the bottom of the mold by means of a double-sided adhesive and using a template rule, in order to ensure precise and reproducible positioning of said PVC strips, and therefore as a corollary non-slip means along the stairs.

Le choix du matériau PVC est avantageux dans la mesure où, en premier lieu, il est inerte vis-à-vis du béton. En second lieu, il est relativement souple et peut être produit à l'aide de filières de manière extrêmement peu onéreuse.The choice of PVC material is advantageous insofar as, first of all, it is inert with respect to concrete. Second, it is relatively flexible and can be produced using dies in an extremely inexpensive manner.

Lorsque l'escalier est installé ou lorsque les plateaux de marche individuels sont montés sur le limon, et uniquement lorsque le chantier total dans lequel s'inscrit l'escalier en question est terminé, il suffit alors de retirer la bande PVC de chacun des plateaux de marche, ladite bande PVC ayant donc protégé pendant toute la durée du chantier, les stries résultant des saillies en relief dont est munie ladite bande PVC, qui ne sont dès lors pas obstruées par les poussières et autres boues ou laitance de béton etc. susceptibles de les obstruer, et en conséquence, d'affecter les propriétés antidérapantes qu'elles sont destinées à assurer.When the staircase is installed or when the individual walking platforms are mounted on the stringer, and only when the total work site in which the staircase in question is registered is completed, it is sufficient to remove the PVC strip from each of the platforms of walking, said PVC strip having therefore protected throughout the duration of the site, the streaks resulting from the raised projections with which said PVC strip is provided, which are therefore not obstructed by dust and other sludge or concrete slurry etc. likely to obstruct them, and consequently to affect the non-slip properties that they are intended to provide.

L'invention concerne également les plateaux de marche en béton pour escaliers préfabriqués en béton, munis sur leur face supérieure au voisinage du nez de marche d'une telle bande PVC escamotable.The invention also relates to concrete walking platforms for precast concrete stairs, provided on their upper face in the vicinity of the stair nosing with such a retractable PVC strip.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On a représenté sur la figure 1 une vue schématique en perspective d'un escalier en béton de facture traditionnelle, c'est-à-dire moulé de manière monobloc. Cet escalier (1) comporte un certain nombre de marches et contremarches (2) présentant au voisinage du nez de marche (3) une bande PVC (4), s'étendant sensiblement sur toute la largeur de ladite marche (2).We have represented on the figure 1 a schematic perspective view of a traditional concrete staircase, that is to say molded in one piece. This staircase (1) comprises a certain number of steps and risers (2) having, in the vicinity of the stair nosing (3), a PVC strip (4), extending substantially over the entire width of said step (2).

On a représenté en relation avec la figure 2 une vue de détail d'une marche ou plateau de marche (2) munie de cette bande PVC (4).We have represented in relation to the figure 2 a detailed view of a step or step (2) fitted with this PVC strip (4).

On a enfin représenté en figure 3 la même vue de détail, dans laquelle la bande PVC (4) a été escamotée, laissant apparaître un certain nombre de rainures ou gorges (5), trois en l'espèce, également orientées selon la dimension principale du plateau de marche (2), c'est-à-dire correspondant à la largeur de la marche.We finally represented in figure 3 the same detail view, in which the PVC strip (4) has been retracted, revealing a certain number of grooves or grooves (5), three in this case, also oriented according to the main dimension of the step plate (2) , i.e. corresponding to the width of the step.

Dans les faits et afin d'aboutir à cet escalier (1), le moule dans lequel il a été réalisé, et plus précisément le fond de moule relatif à chacun des plateaux de marche a préalablement reçu ladite bande PVC (4), collée au moyen d'un adhésif double face contre la face correspondante du moule.In fact and in order to reach this staircase (1), the mold in which it was made, and more precisely the mold base relating to each of the walking platforms, has previously received said PVC strip (4), glued to the using double-sided adhesive against the corresponding side of the mold.

Par ailleurs, afin d'aboutir à un positionnement précis et répété de cette bande PVC (4), l'opérateur utilise une règle gabarit d'un type en soi connu, et ainsi après démoulage on obtient l'escalier représenté sur la figure 1.Furthermore, in order to achieve a precise and repeated positioning of this PVC strip (4), the operator uses a template rule of a type known per se, and thus after demolding, the staircase shown on the figure 1 .

On a représenté plus en détail en relation avec les figures 4 et 5 une bande PVC du type en question. Comme on peut l'observer, celle-ci présente trois stries en saillie (6) reliées entre elles par deux portions planes (7). Dans un exemple de réalisation, la hauteur des stries est voisine de 5 mm, l'épaisseur des portions planes (7) voisine de 0,6 mm et la largeur desdites portions planes (7) voisine de 10 mm. Une telle bande PVC est très facilement réalisable au moyen d'une filière, et ce, à des coûts de revient réduits.We have shown in more detail in relation to Figures 4 and 5 a PVC tape of the type in question. As can be observed, it has three projecting ridges (6) connected to each other by two flat portions (7). In an exemplary embodiment, the height of the ridges is close to 5 mm, the thickness of the flat portions (7) close to 0.6 mm and the width of said flat portions (7) close to 10 mm. Such a PVC strip is very easily achievable by means of a die, and this, at reduced production costs.

Qui plus est, et comme déjà dit, la mise en œuvre de PVC est parfaitement compatible avec le béton puisqu'aussi bien, le PVC est inerte vis-à-vis du béton. Au demeurant, vu la faible épaisseur générale de la bande PVC (4), celle-ci présente une certaine souplesse favorisant sa mise en place au fond du moule dans lequel doivent être moulés l'escalier voire les plateaux de marche.What is more, and as already said, the use of PVC is perfectly compatible with concrete since, as well, PVC is inert with respect to concrete. Moreover, given the general small thickness of the PVC strip (4), it has a certain flexibility favoring its positioning at the bottom of the mold in which the staircase or even the walking platforms must be molded.

La présente invention est également susceptible d'être mise en œuvre dans le cadre des procédés de réalisation d'escaliers monoblocs en béton mettant en œuvre un moule fermé, c'est-à-dire composé d'un moule inférieur et d'un moule supérieur ou capot, définissant entre eux un volume destiné à être rempli par du béton. Un tel procédé est par exemple décrit dans la demande FR 1854813 déposée par le Demandeur.The present invention is also capable of being implemented in the context of methods for producing one-piece concrete stairs using a closed mold, that is to say composed of a lower mold and a mold. upper or cover, defining between them a volume intended to be filled with concrete. Such a process is for example described in the application FR 1854813 filed by the Applicant.

Typiquement, ce procédé consiste :

  • à fixer et installer le moule inférieur en position opérationnelle ;
  • à positionner le moule supérieur ou capot en regard dudit moule inférieur et à le fixer sur ledit moule inférieur ;
  • à injecter dans le volume défini par les deux moules, respectivement inférieur et supérieur, du béton notamment de type autoplaçant, jusqu'à combler l'intégralité dudit volume ;
  • après prise en masse du béton, à ôter le moule supérieur et le moule inférieur et donc à démouler l'escalier ainsi réalisé.
Typically, this process consists of:
  • to fix and install the lower mold in operational position;
  • positioning the upper mold or cover opposite said lower mold and fixing it on said lower mold;
  • injecting into the volume defined by the two molds, respectively lower and upper, concrete in particular of the self-compacting type, until filling the entire volume;
  • after solidification of the concrete, to remove the upper mold and the lower mold and therefore to unmold the staircase thus produced.

L'avantage de ce procédé de réalisation réside notamment dans la diminution des travaux de finition tout particulièrement chronophages, et dans l'optimisation de la sécurité.The advantage of this production process lies in particular in the reduction of particularly time-consuming finishing works, and in the optimization of safety.

On a représenté en relation avec la figure 6 le capot supérieur susceptible d'être mis en œuvre dans le cadre d'un tel procédé. Et on a représenté en relation avec la figure 7 la face inférieure dudit capot supérieur, sur laquelle apparaît au voisinage de ce qui va devenir le nez de marche, la mise en place de la bande PVC conforme à l'invention.We have represented in relation to the figure 6 the upper cover capable of being implemented in the context of such a method. And we have represented in relation to the figure 7 the underside of said upper cover, on which appears in the vicinity of what will become the stair nosing, the establishment of the PVC strip according to the invention.

Ainsi donc, cette bande PVC peut être mise en œuvre dans tous les types d'escaliers en béton dès lors qu'ils sont réalisés par moulage, ce qui est traditionnellement le cas.Thus, this PVC strip can be implemented in all types of concrete stairs as soon as they are made by molding, which is traditionally the case.

On conçoit tout l'intérêt de l'invention dans la mesure où, l'escalier proprement dit ou les plateaux de marche lorsqu'on met en œuvre des limons, sont revêtus aussi longtemps que souhaité, au voisinage du nez de marche, de cette bande PVC. Lorsque le chantier est terminé et seulement lorsqu'il est terminé, on procède alors à l'escamotage de cette bande PVC, qui libère les rainures (5) à fonction antidérapante sans risque de les voir obstruées par les utilisateurs, la poussière, la boue etc. ou la laitance de béton pendant les opérations de chantier.We understand all the interest of the invention insofar as, the staircase itself or the walking platforms when using stringers, are coated as long as desired, in the vicinity of the stair nosing, this PVC tape. When the site is finished and only when it is finished, we then retract this PVC band, which releases the non-slip grooves (5) without the risk of seeing them obstructed by users, dust, mud etc. or the laitance of concrete during site operations.
