Description

L'invention concerne un plancher comprenant des poutrelles en béton et des entrevous coffrants interposés entre ces poutrelles en ayant leurs bords en appui sur ces poutrelles, et une dalle de compression coulée sans couture sur les poutrelles et les entrevous, chaque entrevous comportant deux portions coffrantes définissant avec chaque poutrelle des cavités s'étendant le long de ces poutrelles, le béton contenu dans chaque cavité formant un clavetage de la dalle solidarisant cette dalle à la poutrelle, chaque portion coffrante ayant en section transversale une forme d'arc de concavité tournée vers le haut délimitant toute la face inférieure du clavetage, chaque poutrelle comprenant une face supérieure ainsi que deux flancs au moins partiellement enrobés par les clavetages de la dalle de compression.The invention relates to a floor comprising concrete beams and formwork interjoists interposed between these beams having their edges resting on these beams, and a seamless casting compression slab on the beams and interjoists, each interjoists comprising two formwork portions defining with each beam cavities extending along these beams, the concrete contained in each cavity forming a keyway of the slab solidarisant this slab to the beam, each formwork portion having in cross section a bow shape of concavity turned towards the top delimiting the entire lower face of the keying, each beam comprising an upper face and two flanks at least partially embedded by the keyings of the compression slab.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Lors de la fabrication d'un tel plancher, on installe les poutrelles, puis des entrevous entre chaque paire de poutrelles adjacentes, avant de couler du béton sur l'ensemble pour constituer la dalle de compression.During the manufacture of such a floor, the beams are installed, then interjoists between each pair of adjacent beams, before pouring concrete on the assembly to form the compression slab.

La rigidité en flexion d'un tel plancher est conditionnée par la qualité de la cohésion entre les poutres et la dalle qu'elles supportent. Cette cohésion est considérée comme satisfaisante lorsque la résistance au cisaillement de la liaison entre la poutrelle et la dalle, parallèlement à la poutrelle, est supérieure à une valeur de seuil définie réglementairement en fonction de la configuration du plancher.The flexural rigidity of such a floor is conditioned by the quality of the cohesion between the beams and the slab they support. This cohesion is considered satisfactory when the shear strength of the connection between the beam and the slab, parallel to the beam, is greater than a threshold value defined by regulation according to the configuration of the floor.

Cette résistance peut être évaluée en exerçant sur la poutrelle un effort longitudinal de poussée tendant à l'extraire de la dalle, jusqu'à la valeur d'effort provoquant la décohésion de la poutrelle et de la dalle. La résistance au cisaillement est alors déduite de cette valeur et des paramètres géométriques de la poutre.This resistance can be evaluated by exerting on the beam a longitudinal thrust force tending to extract it from the slab, up to the value of effort causing the decohesion of the beam and the slab. The shear strength is then deduced from this value and the geometric parameters of the beam.

Lorsque la résistance est suffisante, l'ensemble formé par la poutrelle et la portion de dalle qu'elle porte constitue un tout rigidement solidaire. Le moment d'inertie de cet ensemble est alors élevé car il correspond au moment d'inertie de la section que définissent conjointement la poutrelle et la portion de dalle, ce qui confère au plancher une rigidité en flexion importante.When the resistance is sufficient, the whole formed by the beam and the slab portion it carries is a rigidly secured whole. The moment of inertia of this set is then high because it corresponds to the moment of inertia of the section that define together the beam and the slab portion, which gives the floor a high flexural rigidity.

Si la résistance est trop faible, la poutrelle se désolidarise de la dalle de sorte que le moment d'inertie de cet ensemble correspond alors seulement à la somme du moment d'inertie de la section de la poutrelle et de celui de la section de la portion de dalle.If the resistance is too low, the beam dissociates from the slab so that the moment of inertia of this set then corresponds only to the sum of the moment of inertia of the section of the beam and that of the section of the slab portion.

Comme le moment d'inertie d'un élément dépend de sa hauteur élevée au cube, la somme des moments d'inertie de la poutrelle et de la portion de dalle est très inférieure au moment d'inertie de la poutrelle et la dalle considérées comme un tout.Since the moment of inertia of an element depends on its high cubic height, the sum of the moments of inertia of the beam and the portion of slab is much lower than the moment of inertia of the beam and the slab considered as a whole.

Cette résistance au cisaillement peut être assurée par des coutures, c'est à dire en prévoyant des fers dépassant des faces supérieures de chaque poutrelle, et qui sont enrobés dans la dalle de compression.This shear strength can be provided by seams, that is to say by providing irons protruding from the upper faces of each beam, and which are embedded in the compression slab.

Mais lorsque le plancher est coulé sans couture, la résistance au cisaillement est obtenue en prévoyant des clavetages situés au niveau de la face inférieure de la dalle, qui viennent enserrer les flancs de la poutrelle pour augmenter la résistance au cisaillement de la jonction de la poutrelle avec la dalle.But when the floor is poured seamlessly, the shear resistance is obtained by providing keyings located at the lower face of the slab, which encircle the flanks of the beam to increase the shear strength of the junction of the beam with the slab.

Dans le cadre réglementaire français, il est d'usage de mettre en oeuvre un clavetage représenté partiellement en figure 1, selon un plan de coupe transversal par rapport à la direction de ses poutrelles.In the French regulatory framework, it is customary to use a keyway represented partially in figure 1 , according to a sectional plane transverse to the direction of its beams.

Il comprend une poutrelle 1 présentant une section symétrique par rapport à un plan de symétrie médian PM vertical, et ayant la forme de la lettre T renversée. Elle comprend une semelle 2 à section rectangulaire et une âme 3 présentant une section en forme de queue d'aronde qui dépasse d'une face supérieure de cette semelle 2.It comprises a beam 1 having a symmetrical section with respect to a vertical median plane of symmetry PM, and having the shape of the inverted letter T. It comprises a sole 2 of rectangular section and a core 3 having a dovetail-shaped section which protrudes from an upper face of this sole 2.

L'âme est délimitée par une face supérieure 4 plane, prolongée par deux flancs 6 et 7 plans joignant cette face supérieure 4 à la semelle 2. Chaque flanc est incliné par rapport au plan médian PM, d'un angle repéré par 5 pour former un débord repéré par 8.The soul is delimited by a flat upper surface 4, extended by two sides 6 and 7 planes joining this upper face 4 to the sole 2. Each side is inclined relative to the median plane PM, an angle marked by 5 to form an edge marked by 8.

Ce plancher comporte également un entrevous partiellement représenté en figure 1 en y étant repéré par 9. Il comporte un bord inférieur 10, en appui sur une face supérieure latérale de la semelle 2 et qui longe la face latérale 7 de l'âme 3, ainsi qu'une portion voûtée centrale 11 reliée à ce bord inférieur par une paroi intermédiaire 12 de forme creuse.This floor also includes a interjoists partially represented in figure 1 it is marked by 9. It has a lower edge 10, bearing on a lateral upper face of the sole 2 and which runs along the lateral face 7 of the core 3, and a central arched portion 11 connected to this edge lower by an intermediate wall 12 of hollow form.

Les orientations des courbures de la portion centrale 11 et de la paroi intermédiaire sont opposées : lorsque l'entrevous est en place, comme dans la figure 1, sa portion voûtée 11 a sa concavité tournée vers le bas, alors que la concavité de la paroi intermédiaire 12 est tournée vers le haut.The orientations of the curvatures of the central portion 11 and the intermediate wall are opposite: when the interjoists are in place, as in the figure 1 its arched portion 11 has its concavity turned downwards, while the concavity of the intermediate wall 12 is turned upwards.

Chaque clavetage longe une partie supérieure de l'âme 4 en venant en appui sur un flanc de celle-ci. La forme de la section transversale d'un clavetage dépend de la paroi intermédiaire creuse 12 de l'entrevous coffrant qui délimite sa face inférieure.Each keyway runs along an upper portion of the core 4 while bearing on a side thereof. The shape of the cross section of a keyway depends on the hollow intermediate wall 12 of the interlock form that delimits its underside.

Dans les solutions connues, la cohésion entre la poutrelle 1 et la dalle de compression est considérée comme satisfaisante lorsque la section transversale de la poutrelle et du clavetage répondent aux critères ci-après.In known solutions, the cohesion between the beam 1 and the compression slab is considered satisfactory when the cross section of the beam and the keyway meet the criteria below.

L'âme à section en queue d'aronde doit présenter des flancs 6 et 7 inclinés d'un angle 5 devant valoir au moins six pourcent, et cette âme doit avoir une hauteur telle que chaque flanc 6, 7 forme un débord 8 d'au moins quatre millimètres, compte tenu de l'inclinaison à six pourcent.The dovetail-section web must have sidewalls 6 and 7 inclined by an angle of at least six percent, and this web must have a height such that each sidewall 6, 7 forms an overhang 8 of at least four millimeters, considering the inclination to six percent.

En ce qui concerne la section du clavetage, elle doit avoir des dimensions suffisantes pour englober une section de référence minimale à contour trapézoïdal repérée par 13.With respect to the keying section, it must be of sufficient size to enclose a minimum reference section with trapezoidal contour marked with 13.

Ce contour comprend une base longue 14 de cent millimètres prolongeant la face supérieure 4, une base courte 16 de trente millimètres, et un côté 17 de quarante millimètres joignant ces bases et longeant le flanc 7.This outline comprises a long base 14 of one hundred millimeters extending the upper face 4, a short base 16 of thirty millimeters, and a side 17 of forty millimeters joining these bases and skirting the flank 7.

Avec cet agencement, la poutrelle est pincée par les clavetages sur une hauteur relativement importante pour améliorer la résistance au cisaillement longitudinal de la jonction.With this arrangement, the beam is pinched by the keyways over a relatively large height to improve the longitudinal shear strength of the junction.

D'autre part, comme cette poutrelle est en béton sa surface présente des aspérités, de sorte qu'il existe à l'interface de la poutrelle et de la dalle des efforts d'accrochage qui améliorent la résistance au cisaillement de l'ensemble.On the other hand, as this beam is concrete its surface has asperities, so that there is at the interface of the beam and the slab of the attachment forces that improve the shear strength of the assembly.

Plus particulièrement, le flanc 24 comprend une face principale 27 plane et parallèle au plan PM, et une nervure 28 encore appelée clé s'étendant parallèlement à la direction générale de la poutrelle, et dépassant latéralement de la face principale 27 en étant située dans la zone de la face principale 27 qui est la plus proche de la face supérieure 23.More particularly, the flank 24 comprises a main face 27 plane and parallel to the plane PM, and a rib 28 also called key extending parallel to the general direction of the beam, and protruding laterally from the main face 27 being located in the area of the main face 27 which is closest to the upper face 23.

Cette nervure est délimitée par la face supérieure 23 en partie supérieure, ainsi que par une face latérale 29, et par une face oblique 31 joignant cette face latérale 29 à la face principale 27.This rib is delimited by the upper face 23 in the upper part, as well as by a lateral face 29, and by an oblique face 31 joining this lateral face 29 to the main face 27.

La face latérale 29 s'étend perpendiculairement à la face supérieure 23, c'est à dire parallèlement au plan PM, alors que la face oblique est inclinée par rapport à ce plan PM. La jonction entre la face supérieure 23 et la face latérale 29 correspond à une arête supérieure de la poutrelle, repérée par 32.The side face 29 extends perpendicular to the upper face 23, that is to say parallel to the plane PM, while the oblique face is inclined relative to this plane PM. The junction between the upper face 23 and the lateral face 29 corresponds to an upper edge of the beam, indicated by 32.

L'épaisseur de la nervure, notée 33 et correspondant à la distance séparant la face latérale 29 de la face principale 27 selon une direction normale au plan PM, vaut entre quatre et six millimètres.The thickness of the rib, denoted 33 and corresponding to the distance separating the lateral face 29 from the main face 27 in a direction normal to the plane PM, is between four and six millimeters.

La section de la poutrelle étant symétrique par rapport au plan PM, l'autre flanc, à savoir le flanc 26 comporte lui aussi une face principale repérée par 36, ainsi qu'une nervure ou clé 37 dépassant de cette face principale.The section of the beam being symmetrical with respect to the plane PM, the other sidewall, namely the sidewall 26 also has a main face marked by 36, and a rib or key 37 protruding from this main face.

Cette autre nervure 37 est elle aussi délimitée en partie supérieure par la face supérieure 23, latéralement par une face latérale 38 parallèle au plan PM, et en partie inférieure par une face oblique 39.This other rib 37 is also delimited in the upper part by the upper face 23, laterally by a lateral face 38 parallel to the plane PM, and in the lower part by an oblique face 39.

La jonction de la face supérieure 23 avec la face latérale 38 correspond à une arête supérieure de la poutrelle repérée par 41. Cette nervure 37 a la même forme et les mêmes dimensions que la nervure 28.The junction of the upper face 23 with the lateral face 38 corresponds to an upper edge of the beam marked by 41. This rib 37 has the same shape and the same dimensions as the rib 28.

L'entrevous coffrant qui est partiellement représenté en figure 2 en y étant repéré par 42 comprend un bord inférieur 43 en appui sur une face supérieure latérale de la semelle 21, et longeant la face principale 36 du flanc 26.The shuttering interlocking which is partially represented in figure 2 being identified by 42 comprises a lower edge 43 resting on a lateral upper face of the sole 21, and along the main face 36 of the sidewall 26.

Ce bord inférieur 43 est relié à une portion voûtée centrale de l'entrevous, repérée par 44, par une paroi intermédiaire creuse 46, la portion centrale 44 et la paroi intermédiaire ayant des courbures opposées. Ainsi, lorsque l'entrevous est en place comme dans la figure 2, sa portion centrale voûtée 44 a sa face creuse orientée vers le bas alors que la paroi intermédiaire 46 a sa face creuse orientée vers le haut.This lower edge 43 is connected to a central vaulted portion of the interjoists, marked 44, by a hollow intermediate wall 46, the central portion 44 and the intermediate wall having opposite curvatures. So when the interjoists are in place as in the figure 2 its arched central portion 44 has its hollow face facing downwards while the intermediate wall 46 has its hollow face facing upwards.

L'ensemble formé par les entrevous et les poutrelles délimite une surface inférieure sur laquelle est coulée sans couture la dalle de compression non représentée. La paroi intermédiaire 46 constitue une portion creuse coffrante de l'entrevous dont la face supérieure creuse délimite une face inférieure d'un clavetage de cette dalle de compression.The assembly formed by interjoists and beams delimits a lower surface on which is cast seamlessly compression slab not shown. The intermediate wall 46 constitutes a formwork hollow portion of the interjoists whose hollow upper surface delimits a lower face of a keyway of this compression slab.

Ce clavetage s'étend jusque sous la clé 37, de sorte que les trois faces externes de la clé sont enrobées par le clavetage et la dalle de compression.This keying extends to the key 37, so that the three outer faces of the key are coated by the keyway and the compression slab.

Le bord inférieur 43 de l'entrevous longe la face principale 36 du flanc 26, de manière à ne pas laisser passer de béton entre ce bord et le flanc de poutrelle.The lower edge 43 of the interjoists along the main face 36 of the sidewall 26, so as not to allow concrete to pass between this edge and the sidewall.

Le clavetage est donc délimité du côté de la poutrelle par une portion de la face principale 36 et de la nervure 37. La face inférieure de ce clavetage est quant à elle délimitée par la paroi intermédiaire creuse ou bombée 46.The keying is therefore delimited on the side of the beam by a portion of the main face 36 and the rib 37. The lower face of this keying is itself delimited by the hollow or curved intermediate wall 46.

Cette paroi intermédiaire bombée 46 présente une section en forme d'un arc d'ellipse repéré par 47, correspondant au quart inférieur droit d'une ellipse de base centrée sur l'arête en un point repéré par 40.This curved intermediate wall 46 has a section in the form of an elliptical arc indicated by 47, corresponding to the lower right quarter of a base ellipse centered on the edge at a point marked by 40.

Ce point 40 est situé sur la face latérale 38 de la nervure 37, en étant espacé du bord inférieur de cette face latérale d'une distance repérée par 34, et qui vaut entre cinq et vingt-cinq millimètres, préférentiellement dix millimètres.This point 40 is located on the lateral face 38 of the rib 37, being spaced from the lower edge of this lateral face by a distance marked by 34, and which is between five and twenty-five millimeters, preferably ten millimeters.

Le demi-grand axe de cette ellipse est orienté horizontalement et mesure soixante millimètres, et son demi-petit axe, qui est orienté verticalement, mesure quarante millimètres.The semi-major axis of this ellipse is oriented horizontally and measures sixty millimeters, and its half-small axis, which is oriented vertically, measures forty millimeters.

Le clavetage a donc un contour, repéré par 48 dans la figure 2, comprenant un côté 49 formé de trois segments consécutifs, un côté supérieur rectiligne 51 s'étendant parallèlement à la face supérieure 23, et un bord inférieur 47 en forme d'arc d'ellipse.The keying therefore has an outline, marked by 48 in the figure 2 , comprising a side 49 formed of three consecutive segments, a rectilinear upper side 51 extending parallel to the upper face 23, and a lower edge 47 in the shape of an elliptical arc.

Il est à noter que le bord supérieur 51 n'est pas matérialisé physiquement, puisqu'il correspond à la jonction du corps de dalle avec le clavetage, l'ensemble étant coulé en une seule opération.It should be noted that the upper edge 51 is not physically embodied, since it corresponds to the junction of the slab body with the keying, the assembly being cast in a single operation.

Le clavetage a ainsi une forme générale rectiligne à section transversale délimitée par le contour 48, cette forme étant donnée par l'entrevous et par le flanc de poutrelle.The keying thus has a generally rectilinear shape with a cross section delimited by the contour 48, this form being given by the interjoists and the flank of girder.

La poutrelle en béton a sa surface externe avantageusement pourvue d'aspérités ou de reliefs, ce qui augmente encore la résistance au cisaillement longitudinal de la jonction.The concrete beam has its outer surface advantageously provided with asperities or reliefs, which further increases the longitudinal shear strength of the junction.

Avantageusement, l'entrevous est prévu pour compléter cette forme de base, par exemple tous les cent cinquante millimètres le long de la poutrelle, par un renfort transversal, ayant une section transversale significativement supérieure à la section définie par le contour 48.Advantageously, the interjoists are provided to complete this basic form, for example every one hundred and fifty millimeters along the beam, by a transverse reinforcement, having a cross section significantly greater than the section defined by the contour 48.

Dans ce cadre, l'entrevous est avantageusement fabriqué en matière plastique moulée pour former dans celui-ci des rigoles régulièrement espacées et s'étendant perpendiculairement à la direction de la poutrelle, pour mouler et délimiter ces renforts.In this context, the interjoists is advantageously made of molded plastic to form in it regularly spaced channels and extending perpendicular to the direction of the beam, to mold and delimit these reinforcements.

Une telle rigole située en arrière du plan de coupe de la figure 2 est représentée dans celle-ci par le trait 52 correspondant à la face inférieure de cette rigole.Such a channel located behind the cutting plane of the figure 2 is represented in it by the line 52 corresponding to the underside of this channel.

Dans l'exemple des figures, la poutrelle présente une partie supérieure qui s'étend jusque dans la dalle de compression, c'est à dire au delà de la face inférieure de cette dalle de compression.In the example of the figures, the beam has an upper portion that extends into the compression slab, that is to say beyond the lower face of the compression slab.

L'invention n'est pas limitée à cette structure de plancher, et elle s'applique aussi bien à une structure dans laquelle la face supérieure de la poutrelle est à un niveau qui coïncide avec le niveau de la face inférieure de la dalle de compression.The invention is not limited to this floor structure, and it applies equally well to a structure in which the upper face of the beam is at a level which coincides with the level of the lower face of the compression slab .
