Description

La présente invention concerne les escaliers et plus particulièrement les escaliers droits préfabriqués.The present invention relates to staircases and more particularly to prefabricated straight staircases.

Les escaliers préfabriqués en béton permettent généralement de réaliser un gain de temps aussi bien au niveau de la fabrication qu'au niveau de la pose de l'escalier sur le chantier. Les.gains à la fabrication sont bien sûr fonction de la quantité. d'escaliers à produire, ils sont aussi fonction de la simplicité et du nombre d'éléments qui composent l'escalier.Prefabricated concrete staircases generally make it possible to save time both at the manufacturing level and at the installation of the staircase on the site. The manufacturing gains are of course a function of the quantity. stairs to produce, they are also a function of the simplicity and the number of elements that make up the staircase.

L'invention vise à réaliser un escalier adapté à la fois à une industrialisation de la fabrication et à un vaste domaine d'application en raison de sa simplicité. Ce type d'escalier, selon l'invention, convient comme escalier d'entrée d'un pavillon, escalier de cave, escalier d'intérieur de bâtiment ; il est facile à poser sans engin de manutention en raison de son poids réduit. Les éléments de marches qui le composent permettent une grande. souplesse d'utilisation allant de l'escalier abrupt à l'escalier plus allongé, chaque marche restant parfaitement horizontale quelle que soit la pente de l'escalier.The invention aims to produce a staircase adapted both to an industrialization of manufacturing and to a wide field of application because of its simplicity. This type of staircase, according to the invention, is suitable as an entrance staircase for a pavilion, cellar staircase, interior building staircase; it is easy to install without handling equipment due to its reduced weight. The elements of steps which compose it allow a great. flexibility of use going from the steep staircase to the more elongated staircase, each step remaining perfectly horizontal whatever the slope of the staircase.

L'escalier, selon l'invention, est constitué d'au moins un limon et de marches ;. le ou chaque limon comporte des échancrures transversales d'ancrage d'éléments de marches préfabriqués. L'élément préfabriqué est constitué d'une marche moulée avec une paroi perpendiculaire formant d'une part la contremarche et d'autre part un pied d'ancrage se positionnant dans l'échancrure du limon.The staircase, according to the invention, consists of at least one stringer and steps; the or each stringer has transverse notches for anchoring prefabricated step elements. The prefabricated element consists of a molded step with a perpendicular wall forming on the one hand the riser and on the other hand an anchoring foot positioned in the notch of the stringer.

Chaque échancrure du limon a une section en forme de Vé arrondi au niveau de la pointe. Cet arrondi a un rayon sensiblement égal à la moitié de l'épaisseur du pied d'ancrage de façon à correspondre à l'arrondi du dit pied d'ancrage permettant ainsi un pivotement du pied d'ancrage, et donc de l'élément de marche, dans l'échancrure correspondante.Each notch of the stringer has a V-shaped section rounded at the tip. This rounding has a radius substantially equal to half the thickness of the anchoring foot so as to correspond to the rounding of said anchoring foot thus allowing pivoting of the anchoring foot, and therefore of the element of walking, in the corresponding notch.

Selon une autre disposition de l'invention, le dessous de chaque marche comporte un talon obtenu directement du moulage de l'élément de marche ; ce talon est muni d'une face inclinée en contact avec l'arête de l'extrémité supérieure arrière de la contremarche. Le plan passant par la face inclinée est sensiblement perpendiculaire au limon dans sa position moyenne d'inclinaison.According to another arrangement of the invention, the bottom of each step has a heel obtained directly from the molding of the step element; this heel is provided with an inclined face in contact with the edge of the rear upper end of the riser. The plane passing through the inclined face is substantially perpendicular to the stringer in its average position of inclination.

Le dessin annexé illustre, à titre d'exemple, un mode de réalisation d'un escalier conforme à la présente invention.The appended drawing illustrates, by way of example, an embodiment of a staircase in accordance with the present invention.

L'escalier tel que représenté est disposé entre un niveau de sol 1 et le palier d'un niveau supérieur 2. Le ou chaque limon 3 de l'escalier est préfabriqué en béton sous forme de poutre ; il est mis en place et scellé dans des logements 4 et 5 préparés au niveau 1 et au niveau 2. Ces logements sont adaptas aux extrémités des limons, lesquelles extrémités sont soit perpendiculaires à l'axe longitudinal du limon, soit horizontales comme présentées sur la figure . Le ou chaque limon 3 est ancré à sa partie basse sur le niveau 1 et il est fixé au niveau 2 au moyen d'un dispositif d'assemblage connu sous le nom de rail HALFEN ; un rail est noyé a la partie supérieure du limon au moment du moulage et sa partie débordante en queue d'aronde, s'emboite dans une forme complémentaire 5 noyée sous le niveau 2, de sorte que le limon peut être mis en place par une ou deux personnes et son scellement est effectué à la partie basse, au niveau du logement 4, en même temps que la pose du premier élément de marche préfabriqué 6. Ce premier élément 6 sert de référence pour le bétonnage du niveau 1. La marche 7 étant encastrée dans ce bétonnage. L'élément de marche préfabriqué 6 est constitué de la marche 7 proprement dite et d'une paroi verticale 8 servant d'une part de contremarche 9 et de pied d'ancrage 10 d'autre part, lequel pied d'ancrage dépasse le dessous de la marche d'une hauteur sensiblement égale à l'épaisseur de la dite marche. La marche 7 et la paroi 8 sont monoblocs ; elles sont en béton, obtenues par moulage et armées selon le cas. Le pied d'ancrage 10 est disposé dans la première échoncrure 11 à la partie basse du limon et prend appui sur le fond horizontal de celle-ci. Les échancrures 11 sont disposées transversalement et sont espacées régulièrement sur la face supérieure du ou de chaque limon 3 ; elles sont obtenues par moulage et ont une section en Vé avec un arrondi au niveau de la pointe. Cet arrondi, qui correspond à une portion d'enveloppe de cylindre à laquelle se raccordent,les flancs du Vé formant l'échancrure 11 reçoit le pied d'ancrage 10 de l'élément de marche 6. Le rayon de l'arrondi est sansiblement égal à la moitié de l'épaisseur du pied d'ancrage 10. Le dit pied d'ancrage a son extrémité inférieure arrondie également pour épouser la forme du fond de l'échancrure 11. L'ouverture du Vé de l'échancrure correspond à l'angle formé par la paroi 8 dans ses positions extrêmes d'inclinaison.The staircase as shown is arranged between a ground level 1 and the landing of an upper level 2. The or each stringer 3 stairs are precast in concrete in the form of a beam; it is placed and sealed in housings 4 and 5 prepared at level 1 and at level 2. These housings are adapted to the ends of the stringers, which ends are either perpendicular to the longitudinal axis of the stringers, or horizontal as shown on the figure. The or each stringer 3 is anchored at its lower part on level 1 and it is fixed at level 2 by means of an assembly device known by the name of HALFEN rail; a rail is embedded in the upper part of the stringer at the time of molding and its protruding part in a dovetail, fits into a complementary shape 5 embedded under level 2, so that the stringer can be put in place by a or two people and its sealing is carried out at the bottom, at the level of the housing 4, at the same time as the installation of the first prefabricated step element 6. This first element 6 serves as a reference for the concreting of level 1. The step 7 being embedded in this concreting. The prefabricated step element 6 consists of the step 7 proper and a vertical wall 8 serving on the one hand as riser 9 and anchor foot 10 on the other hand, which anchor foot protrudes below of the step of a height substantially equal to the thickness of said step. The step 7 and the wall 8 are in one piece; they are made of concrete, obtained by molding and reinforced as appropriate. The anchoring foot 10 is disposed in the first ridge 11 at the bottom of the stringer and rests on the horizontal bottom thereof. The notches 11 are arranged transversely and are regularly spaced on the upper face of the or each stringer 3; they are obtained by molding and have a V-shaped section with a rounding at the point. This rounding, which corresponds to a portion of the cylinder casing to which the sides of the Vee forming the notch 11 are connected, receives the anchoring foot 10 of the step element 6. The radius of the rounding is obviously equal to half the thickness of the anchor foot 10. Said anchor foot has its rounded lower end also to match the shape of the bottom of the notch 11. The opening of the V of the notch corresponds to the angle formed by the wall 8 in its extreme positions of inclination.

Pour conserver une parfaite horizontalité des marches 7 selon les inclinaisons du ou de chaque limon 3, la hauteur obtenue entre les dites marches 7 peut varier tout en restant uniforms d'une marche à l'autre, au moyen d'un talon 12 disposé sous chaque marche. Ce talon 12 comporte une face inclinée 13 en contact avec l'arête supérieure arrière 14 de la contremarche 9. Le talon 12 est obtenu directement par moulage, il s'étend sur toute la partie inférieure de la marche. La face inclinée 13 du talon est sensiblement plane, et elle se situe dans un plan qui est perpendiculaire à la position moyenne du ou de chaque limon 3 c'est-à-dire entre son inclinaison maximum et son inclinaison minimum. Lorsque le limon est à son inclinaison la plus faible, la marche 7 repose sur la contremarche 9 ; l'arête 14,est en contact avec l'extrémité supérieure de la face inclinée 13 du talon 12. L'inclinaison maximale du limon est obtenue lorsque l'arête 14 est située a l'extrémité inférieure de la face inclinée 13 du talon 12. L'espace 15 entre le dessous de la marche 7 et la partie supérieure de la contremarche 9 est rempli de béton pour renforcer l'assise de la marche sur la contremarche. L'arête 14 de la contremarche 9 peut d'autre part, être légèrement arrondie pour éviter une trop grande fragilité.To maintain perfect horizontality of the steps 7 according to the inclinations of the or each stringer 3, the height obtained between said steps 7 may vary while remaining uniform from one step to another, by means of a heel 12 disposed under each step. This heel 12 has an inclined face 13 in contact with the rear upper edge 14 of the riser 9. The heel 12 is obtained directly by molding, it extends over the entire lower part of the step. The inclined face 13 of the heel is substantially planar, and it lies in a plane which is perpendicular to the average position of the or each stringer 3, that is to say between its maximum inclination and its minimum inclination. When the stringer is at its lowest inclination, the step 7 rests on the riser 9; the edge 14 is in contact with the upper end of the inclined face 13 of the heel 12. The maximum inclination of the stringer is obtained when the edge 14 is located at the lower end of the inclined face 13 of the heel 12 The space 15 between the underside of the step 7 and the upper part of the riser 9 is filled with concrete to strengthen the base of the step on the riser. The edge 14 of the riser 9 can, on the other hand, be slightly rounded to avoid excessive fragility.

La réalisation de l'escalier s'effectue par le montage successif des éléments de marche 6 en superposition, par la mise en appui des pieds d'ancrage des dits éléments dans les éehan- crures 11 régulièrement espacées sur le ou chaque limon.The staircase is produced by successively mounting the tread elements 6 in superposition, by pressing the anchoring feet of said elements in the notches 11 regularly spaced on the or each stringer.

La dernière échancrure supérieure 11 reçoit l'élément préfabriqué supérieur 6 sur la contremarche duquel viendra s'appuyer la marche palière 16 constituée d'une dalle scellée sur le palier du niveau 2 dans le prolongement de la chape 17 ; la marche palière peut également être réalisée directement, par un coffrage sur la dernière contremarche, au moment du coulage de la chape 17 du niveau 2.The last upper notch 11 receives the upper prefabricated element 6 on which the riser will come to bear the landing step 16 consisting of a slab sealed on the landing of level 2 in the extension of the yoke 17; the landing step can also be carried out directly, by a formwork on the last riser, when the screed 17 of level 2 is poured.

De la description qui précède, il ressort que l'invention permet la réalisation d'escaliers plus ou moins abrupts à l'aide des mêmes éléments de marches préfabriqués dans lesquels escaliers le nez de marche est plus ou moins prononcé. La largeur de l'élément préfabriqué est variable selon la largeur de l'escalier à réaliser et cet élément peut être supporté par un limon central large ou par plusieurs limons comportant chacun des échancrures de positionnement des pieds d'ancrage.From the above description, it appears that the invention allows more or less steep stairs to be produced using the same prefabricated step elements in which the stair nosings are more or less pronounced. The width of the prefabricated element is variable depending on the width of the staircase to be made and this element can be supported by a wide central stringer or by several strings each having indentations for positioning the anchoring feet.

L'invention ne se limite aucunement au mode de réalisation spécialement indiqué, mais elle couvre également toutes les variantes.possibles à condition que celles-ci ne soient pas en contradiction avec l'objet de chacune des revendications annexées à la présente description.The invention is in no way limited to the specially indicated embodiment, but it also covers all possible variants, provided that these are not in contradiction tion with the subject of each of the claims appended to this description.
