Abstract

The prefabricated concrete stairway for a building is formed from separate sections each with a tread having the side edges extended by a bonder of greater height than the tread. The bonder extends perpendicular to the tread and has a pair of openings aligned with adjacent upper and lower treads. When the tread sections are assembled, the openings form channels to receive metal reinforcing rods, after which the channels are filled with cement.

Description

<B><U>ESCALIER</U></B><U> DROIT</U> PREFABRIQUE <B><U>EN</U></B> BETON L'invention concerne un escalier droit du type préfabriqué en béton. <B> <U> STAIR </ U> </ B> <U> LAW </ U> PREFABRIC <B> <U> EN </ U> </ B> CONCRETE The invention relates to a straight staircase of the prefabricated type in concrete.

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 pose de l'escalier sur le chantier, et d'autre un gain réel en termes de 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 installation of the staircase on the building site, and other a real gain in terms of cost.

Parmi les escaliers du type préfabriqué de l'art antérieur, on peut exemple citer celui décrit le document EP-A-0 <B>126 6 8 1.</B> Among the stairs of the prefabricated type of the prior art, it is possible to cite the one described in document EP-A-0 <B> 126 6 8 1. </ B>

Celui-ci constitué d'un limon, préalablement mis en place entre deux étages ou les deux lieux<B>à</B> relier par l'escalier, ledit limon étant pourvu d'un certain nombre d'échancrures sur sa face supérieure, ménagées<B>à</B> intervalles réguliers, et destinées<B>à</B> recevoir base ou pied d'ancrage de chaque élément de marche, ledit pied d'ancrage se poursuivant verticalement afin de constituer la contremarche de la marche supérieure immédiatement adjacente. Chacun des marches comporte en outre un épaulement, destiné<B>à</B> venir se positionner contre ladite contremarche de la marche inférieure. This consisting of a silt, previously set up between two floors or the two places <B> to </ B> connect by the stairs, said silt being provided with a number of indentations on its upper face , arranged at regular intervals, and intended to receive base or anchor foot of each step element, said anchor foot continuing vertically to constitute the riser of the top step immediately adjacent. Each of the steps further comprises a shoulder, intended <B> to </ B> to be positioned against said riser of the lower step.

Bien que satisfaisant sur le plan technique, ce type d'escalier nécessite donc au préalable la mise en #uvre d'un limon, qu'il convient tout d'abord de réaliser, et ensuite mettre en place, avant de procéder effectivement<B>à</B> la pose des éléments constitutifs des marches. Although technically satisfactory, this type of staircase therefore requires the prior implementation of a silt, which must first be realized, and then put in place, before actually proceeding <B > to </ B> laying the constituent elements of the steps.

L'objet l'invention est de simplifier outre bien entendu la mise en place de ces escaliers, mais également sa réalisation, en s'affranchissant notamment de la réalisation d'une telle structure de soutien. The object of the invention is to simplify additionally of course the establishment of these stairs, but also its realization, in particular by avoiding the realization of such a support structure.

L'escalier conforme<B>à</B> l'invention est donc un escalier droit préfabriqué en béton, constitué par l'assemblage d'éléments de marche préfabriqués, et se caractérise en ce que lesdits éléments de marche sont chacun constitués d'une marche proprement dite, dont l'un des deux bords latéraux se prolonge par un parpaing ou équivalent, dont l'une des faces est située dans le plan de ladite marche, ledit parpaing s'étendant selon une direction sensiblement perpendiculaire<B>à</B> la marche et étant percé d'au moins un orifice traversant, et présentant en outre un autre orifice parallèle au premier, non traversant l'orifice traversant d'un élément de marche étant destiné<B>à</B> venir<B>à</B> l'aplomb de l'orifice non traversant de la marche inférieure, lorsque l'escalier est place, afin de constituer une cavité linéaire propre<B>à</B> recevoir un ferraillage de renfort mécanique et destinée<B>à</B> être remplie de béton, de telle sorte<B>à</B> constituer une structure de soutien assurant cohésion<B>à</B> l'escalier. The staircase according to the invention is therefore a straight prefabricated concrete staircase consisting of the assembly of prefabricated walking elements, and is characterized in that said walking elements each consist of a step proper, one of the two side edges is extended by a block or equivalent, one of whose faces is located in the plane of said step, said block extending in a substantially perpendicular direction <B> at </ B> the step and being pierced with at least one through hole, and further having another orifice parallel to the first, not through the through hole of a step member being intended <B> to </ B > come <B> to </ B> perpendicular to the non-through hole of the lower step, when the staircase is placed, in order to constitute a clean linear cavity <B> to </ B> receive a reinforcement of mechanical reinforcement and intended <B> to </ B> be filled with concrete, so <B> to </ B> build a support structure ensuring cohesion <B> to </ B> the staircase.

En d'autres termes, l'escalier conforme<B>à</B> l'invention vise<B>à</B> s'affranchir de toute structure de pose ou de soutien additionnelle, dans la mesure où parpaings constitutifs des éléments de marche viennent se poser les uns sur les autres, avec un décalage sensiblement périodique, et où la cohésion est assurée par la solidarisation des parpaings entre eux deux<B>à</B> deux par ferraillage et béton coulé. In other words, the staircase conforming to the invention aims to overcome any additional installation or support structure, inasmuch as the constituent blocks of walking elements come to rest on each other, with a substantially periodic shift, and where the cohesion is ensured by the joining of the blocks between them two <B> to </ B> two by reinforcement and poured concrete.

Dans une première forme de réalisation de l'invention, l'escalier est exempt de toute contremarche. In a first embodiment of the invention, the staircase is free of any risers.

Dans une autre forme de réalisation, l'escalier est muni de contremarche, 'étendant<B>à</B> partir du bord avant de la marche, et destinée<B>à</B> venir prendre appui sur la marche de l'élément de marche inférieur. In another embodiment, the staircase is provided with a riser, extending <B> from the front edge of the step, and intended to bear on the step of the lower step element.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux des exemples de réalisation qui suivent, donnés<B>à</B> titre indicatif et non limitatif<B>à</B> l'appui des figures annexées. The way in which the invention can be realized and the advantages which result from it will emerge better from the following exemplary embodiments, given <B> to </ B> indicative and non-limiting <B> to </ B> the support of annexed figures.

La figure<B>1</B> est une représentation schématique en perspective vue du devant de l'escalier droit préfabriqué conforme<B>à</B> une première forme de réalisation de l'invention, ne mettant pas en #uvre de contremarche. Figure <B> 1 </ B> is a schematic perspective view from the front of the straight prefabricated staircase <B> to </ B> a first embodiment of the invention, not implementing riser.

La figure 2 est une vue analogue<B>à</B> la figure<B>1,</B> mais vue de derrière. Figure 2 is a view similar to Figure 1, but seen from behind.

La figure<B>3</B> est une représentation schématique en perspective de l'un éléments de marche constitutif dudit escalier des figures<B>1</B> et 2. Figure <B> 3 </ B> is a diagrammatic representation in perspective of a constituent walking element of said staircase of Figures <B> 1 </ B> and 2.

La figure 4 est une représentation schématique en section longitudinale de l'élément de marche de la figure<B>3,</B> et la figure<B>5</B> est une représentation schématique en vue latérale dudit élément. FIG. 4 is a diagrammatic representation in longitudinal section of the step element of FIG. 3, and FIG. 5 is a diagrammatic representation in side view of said element.

Les figures<B>6 à 10</B> sont des vues analogues aux figures<B>1<I>à</I> 5</B> d'une seconde forme de réalisation de l'invention mettant en #uvre des contremarches. On a représenté au sein de la figure<B>3,</B> une vue en détail de la structure d'un élément de marche mis en #uvre dans une première forme de réalisation de l'invention. Fondamentalement, celui-ci comporte une marche proprement dite (2), plane, dont l'un des bords latéraux<B>(3)</B> se prolonge,<B>à</B> angle droit,<B>à</B> la fois en hauteur et en largeur, avec un parpaing (4). De fait, ce parpaing (4) présente hauteur bien supérieur<B>à</B> la marche (2), ainsi qu'on peut en<B>j</B>uger<B>à</B> l'analyse des figures. Figures <B> 6 to 10 </ B> are views similar to Figures <B> 1 <I> to </ I> 5 </ B> of a second embodiment of the invention implementing risers. FIG. 3 shows a detailed view of the structure of a step element used in a first embodiment of the invention. Basically, it has a step itself (2), flat, one of the side edges <B> (3) </ B> extends, <B> to </ B> right angle, <B> both in height and in width, with a block (4). In fact, this block (4) has a much higher height <B> at </ B> step (2), so we can <B> j </ B> uger <B> to </ B> l analysis of the figures.

Avantageusement, l'ensemble marche (2) + parpaing est issu de moulage et bien entendu réalisé en béton. Advantageously, the assembly walk (2) + block is derived from molding and of course made of concrete.

Comme on peut l'observer sur la figure<B>3,</B> le parpaing est percé de deux orifices<B>(5)</B> et<B>(6),</B> l'orifice<B>(6)</B> étant en outre traversant, et donc s'etendant selon toute sa hauteur. De la sorte, lorsque les éléments de marche<B>(1)</B> sont montés les sur les autres, ainsi que cela est représenté sur les figures<B>1</B> et<B>3,</B> l'orifice traversant<B>(6)</B> d'un élément de marche supérieur, est aligné avec l'orifice<B>(5)</B> de l'élément marche inférieur, de telle sorte<B>à</B> former une cavité continue. As can be seen in figure <B> 3, </ B> the breeze block is pierced with two holes <B> (5) </ B> and <B> (6), </ B> the hole <B> (6) </ B> also crossing, and thus extending to its full height. In this way, when the walking elements <B> (1) </ B> are mounted on the others, as shown in Figures <B> 1 </ B> and <B> 3, </ B> the through hole <B> (6) </ B> of an upper step element, is aligned with the <B> (5) </ B> hole of the bottom step element, so that <B> to </ B> form a continuous cavity.

Cette cavité est destinée<B>à</B> recevoir des éléments ferraillage pour assurer un renfort mécanique. Après mise en place de ces derniers coule du béton<B>à</B> l'intérieur de cette cavité jusqu'à la remplir complètement et venir araser au niveau du plan supérieur du parpaing (4) et de la marche (2). This cavity is intended to receive reinforcing elements to provide mechanical reinforcement. After installation of these flows concrete <B> to </ B> the interior of this cavity to fill completely and come to level with the upper plane of the breeze block (4) and the step (2) .

Afin de renforcer mécaniquement le porte-à-faux de la marche (2), il peut être avantageux de munir la sous-face d'un renfort<B>(7),</B> typiquement de forme arrondie, tel que représenté sur les figures 2<B>à 5.</B> Ce renfort résulte du moulage, et ne nécessite pas la mise en #uvre de structure rapportée, de sorte que la fabrication des éléments de marche demeure simplifiée. In order to mechanically strengthen the overhang of the step (2), it may be advantageous to provide the underside with a reinforcement <B> (7), typically of rounded shape, as shown in Figures 2 <B> to 5. </ B> This reinforcement results from the molding, and does not require the implementation of reported structure, so that the manufacture of the walking elements remains simplified.

Par ailleurs, si pour des raisons esthétiques une forme arrondie a été représentée pour ce renfort<B>(7)</B> sur les figures, il est bien entendu qu'il peut adopter toute autre forme, dès lors que la fonction renfort est préservée. Moreover, if for aesthetic reasons a rounded shape has been shown for this reinforcement <B> (7) </ B> in the figures, it is understood that it can adopt any other form, since the reinforcement function is preserved.

Selon une autre forme de réalisation de l'invention, les éléments de marche<B>(1)</B> comporte outre la marche (2) et le parpaing (4), également une contremarche<B>(9).</B> Avantageusement, cette contremarche est également issue de moulage. Elle étend<B>à</B> partir du bord avant<B>(8)</B> de la marche selon la même hauteur que celle du parpaing (4). Elle est destinée<B>à</B> prendre appui sur la marche l'élément de marche 'diatement inférieur. According to another embodiment of the invention, the walking elements <B> (1) </ B> comprises in addition to the step (2) and the breeze block (4), also a riser <B> (9). Advantageously, this riser is also molded. It extends <B> to </ B> from the front edge <B> (8) </ B> of the walk at the same height as the breeze block (4). It is intended to support the walking element, which is less important.

En revanche, le principe de mise en #uvre demeure identique a celui de la forme de réalisation précédente. On the other hand, the implementation principle remains identical to that of the previous embodiment.

La mise en #uvre d'une telle structure permet ainsi la réalisation d'escaliers préfabriqués en béton de manière très simple puisque ne nécessitant pas notamment la mise en place d'un limon ou crémaillère préalable. The implementation of such a structure allows the realization of prefabricated concrete stairs in a very simple way since not particularly requiring the establishment of a slime or rack prior.

On facilite en outre le transport et le stockage des éléments constitutifs d'un tel escalier.It also facilitates the transport and storage of the constituent elements of such a staircase.
