Description
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 process for the production, on site or in the factory, of concrete stairs and also for the production of concrete tread plates, intended to be positioned on a stringer installed on a construction 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 treads resulting from this process, as well as the stairs resulting from such a process.
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.The realization of concrete stairs is widely used today. Whether it is made 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 the portions of the staircase. staircase, suitable for positioning 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.Stairs of the prefabricated type are also known, also made of concrete, made up of modular elements, capable of facilitating their movement on site and their assembly. These stairs typically comprise a stringer on which are added and fixed elements or treads, 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 stairs, it is required for a certain number of applications the presence on the tread plates of non-slip elements, in particular when the stairs are intended to be subjected to bad weather, therefore outside the buildings, in order to avoid any slipping of the borrowers of these staircases.
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 antidérapanteThese non-slip elements most often consist of linear streaks made directly on the concrete on the upper surface of the tread in question, typically using a groover. In addition to the considerable dust generated by the production of these streaks and, moreover, the lack of straightness, it is quite frequent that during the construction of the building site in question, these streaks are clogged by the dust from the site, conveyed to this level by workers and other stakeholders on said site. In doing so, once blocked, the grooves in question no longer fulfill their anti-slip function.

Le document
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.Also known is the implementation of inserts attached to the treads in question and fixed permanently to said surface. If, when the stairs provided 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 bad weather, again affecting their non-slip function.
Au demeurant, leur fixation impose une étape supplémentaire lors de la réalisation de l'escalier.Moreover, their fixing imposes an additional step during the realization of the staircase.
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, both simple to implement, particularly when carrying out construction sites.
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 making a concrete staircase whose treads are provided with non-slip means and implementing the molding of the staircase itself or the molding of the treads in an individualized manner 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 step nosing of the treads, with a PVC strip provided with longitudinal grooves, the said projecting grooves being oriented towards the inside 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 itself, or of the treads themselves, in providing the corresponding mold with a PVC strip provided with projecting streaks, intended after demolding to remain on the upper face of the treads for a period chosen by the designer, to then be retracted or removed, said PVC strip defining on said upper face of the treads, and typically in the vicinity of the nosing, longitudinal grooves or grooves capable of generating 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 ridges are oriented parallel to the main direction of the tread(s) and typically perpendicular to the main direction of the stringer or the staircase.
Typiquement ces stries sont au nombre de trois, ce nombre n'étant cependant nullement limitatif.Typically these ridges are three in number, this number however not being 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 of the anti-slip means throughout the staircase.
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, in the first place, it is inert vis-à-vis the concrete. Second, it is relatively flexible and can be produced using dies extremely inexpensively.
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 treads are mounted on the stringer, and only when the total construction site in which the staircase in question is part is finished, it is then sufficient to remove the PVC strip from each of the trays walking, said PVC strip having therefore protected throughout the duration of the construction site, the streaks resulting from the projections in relief with which said PVC strip is provided, which are therefore not obstructed by dust and other sludge or concrete laitance, etc. liable to obstruct them, and consequently to affect the non-slip properties which they are intended to ensure.
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 step trays for precast concrete stairs, provided on their upper face in the vicinity of the stair nosing with such a retractable PVC strip.

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 achieve this staircase (1), the mold in which it was made, and more precisely the bottom of the mold relating to each of the treads, has previously received said PVC strip (4), glued to the means of a double-sided adhesive against the corresponding face of the mould.
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
On a représenté plus en détail en relation avec les
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.Moreover, and as already said, the implementation of PVC is perfectly compatible with concrete since PVC is inert vis-à-vis concrete. Moreover, given the low general thickness of the PVC strip (4), the latter has a certain flexibility favoring its positioning at the bottom of the mold in which the staircase or even the treads 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
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.
- fixing and installing the lower mold in operational position;
- in 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 moulds, respectively lower and upper, concrete in particular of the self-compacting type, until all of said volume is filled;
- 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 method lies in particular in the reduction of finishing work, which is particularly time-consuming, and in the optimization of safety.
On a représenté en relation avec la
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 when 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 conceive the whole advantage of the invention insofar as, the staircase itself or the tread plates when stringers are implemented, are coated for as long as desired, in the vicinity of the stair nosing, with this PVC tape. When the site is finished and only when it is finished, we then proceed to the retraction of this PVC strip, which frees the grooves (5) with a non-slip function without the risk of seeing them obstructed by users, dust, mud etc or concrete laitance during site operations.
