Abstract

The invention relates to a ribbed precast element made of reinforced, possibly prestressed, concrete involved in the construction of slabs, in particular of floors and of roof decking. It is characterised in that, independently of any possible intermediate rib 3, each beam 1, 1' comprises at least two lateral ribs, the layout and cross-section of which are such that their external lateral face 15, 16 is located in the plane of juxtaposition of the beams which, thus, bear against each other or against a wall over the whole external surface of their ribs. Application to the building industry.

Description

L'invention se rapporte à un élément préfabriqué nervuré en béton armé éventuellement précontraint, entrant dans la réalisation de dalles, notamment de planchers et de sous-toitures. The invention relates to a prefabricated ribbed element in possibly prestressed reinforced concrete, used in the production of slabs, in particular floors and under-roofs.

Elle se rapporte également aux dalles obtenues avec de tels éléments ainsi que leur procédé de fabrication et aux moyens en vue de la mise en oeuvre de ce procédé. It also relates to the slabs obtained with such elements as well as their manufacturing process and to the means for the implementation of this process.

Parmi les éléments préfabriqués nervurés entrant dans la réalisation de dalles, au lieu de plaques de dimensions transversales et longitudinales qui ne représenteflt chacune qu'une fraction des dimensions correspondantes de la dalle à réaliser et nécessitent donc d'entre portées par des appuis intermédiaires tels des longerons ou des murs, l'invention se rapporte exclusivement aux éléments autoportants en forme de poutrelles nervurées longitudinalement comprenant une table dont la longueur correspond h l'une des dimensions longitudinale et transversale de la dalle b réaliser et dont de ce fait seule la largeur ne correspond qu'b une fraction de autre dimension de la dalle. Among the prefabricated ribbed elements used in the production of slabs, instead of plates of transverse and longitudinal dimensions which each represent only a fraction of the corresponding dimensions of the slab to be produced and therefore require between them carried by intermediate supports such as stringers or walls, the invention relates exclusively to self-supporting elements in the form of longitudinally ribbed beams comprising a table whose length corresponds to one of the longitudinal and transverse dimensions of the slab to be produced and of which therefore only the width does not corresponds to a fraction of another dimension of the slab.

Sur le chantier, pour constituer la dalle, ces éléments sont évidemment directement juxtaposées, en appuyant leurs extrémités sur les murs porteurs d'une construction. On the construction site, to form the slab, these elements are obviously directly juxtaposed, by pressing their ends on the load-bearing walls of a construction.

Puis, entre chaque paire de poutrelles juxtaposées, est réalisé un joint
A ce jour, on connait déjh de telles poutrelles (FR-A-2.488.303). Elles sont généralement réalisées selon un procédé dit d'extrusion ou par coulée dans un moule perdu en matériau isolant. Dans tous les cas, abstraction faite de 1 'éventuel isolant, la situation de leur nervurage longitudinal par rapport aux champs de leur table leur confère, en section, la forme d'un Té unique ou plus généralement au moins double, ceci bien entendu pour obtenir une poutrelle plus stable et plus large, afin de limiter le nombre de joints à réaliser.Then, between each pair of juxtaposed beams, a joint is made
To date, we already know such beams (FR-A-2,488,303). They are generally produced according to a so-called extrusion process or by casting in a lost mold made of insulating material. In all cases, apart from any insulation, the situation of their longitudinal ribbing relative to the fields of their table gives them, in section, the shape of a single tee or more generally at least double, this of course for obtain a more stable and wider beam, in order to limit the number of joints to be made.

Du fait de cette section, ces poutrelles ne s'appuient l'une contre l'autre que par les champs de leur table. Because of this section, these beams only lean against each other by the fields of their table.

Aussi, pour loger les joints, ce n'est que dens l'épaisseur de leur table et même dans seulement une partie de cette épaisseur, que ces poutrelles présentent deux rainures débouchant à la fois sur leur face supérieure et chacune sur l'un des champs de sa table de manière qu'après la juxtaposition des- poutrelles, les rainures des champs forment ensemble des gorges symétriques ne débouchant que sur la face supérieure de la dalle. Also, to accommodate the joints, it is only in the thickness of their table and even in only part of this thickness, that these beams have two grooves opening both on their upper face and each on one of the fields of its table so that after the juxtaposition of the beams, the grooves of the fields together form symmetrical grooves opening out only on the upper face of the slab.

Pour retenir le matériau constituant le joint, lequel matériau, après durcissement, assurera alors en outre un relatif clavetage des poutrelles entre elles, ces gorges ont une section en queue d'aronde et pour y parvenir les rainures des poutrelles ont donc une section en forme de trapèze rectangle. To retain the material constituting the joint, which material, after hardening, will then also ensure relative keying of the beams between them, these grooves have a dovetail section and to achieve this the grooves of the beams therefore have a shaped section of trapezoid rectangle.

Du fait de sa section en simple queue d'aronde, le clavetage ne résiste à l'extraction que par sa base. De plus, ne disposant pour ce clavetage que d'une partie de l'épaisseur de la table, sa section est évidemment très limitée comme l'est donc l'effort qu'il peut supporter. Due to its simple dovetail section, the keying only resists extraction by its base. In addition, having for this keying only a part of the thickness of the table, its section is obviously very limited as is the effort it can withstand.

Outre, ces problèmes de jonction des poutrelles entre elles, leur section en simple ou multiple Té fait aussi que d'une part les première et dernière poutrelles ne jouxtent les murs correspondants de la construction que par le champs de leur table et que d'autre part, à leurs extrémités, elles n'appuient sur les murs que par au moins une nervure qui est perpendiculaire aux murs porteurs ce qui, dans les deux cas, rend difficile sinon impossible une liaison mécanique entre mur et poutrelle, par exemple par des boulons traversant des perçages de la poutrelle ou dont la tête du corps est retenue dans des gorges présentées è cet effet par les bords de ladite poutrelle. In addition, these problems of joining the beams together, their section in single or multiple T also means that on the one hand the first and last beams adjoin the corresponding walls of the construction only by the field of their table and that other hand, at their ends, they only support the walls by at least one rib which is perpendicular to the load-bearing walls which, in both cases, makes difficult if not impossible a mechanical connection between wall and beam, for example by bolts passing through the holes of the beam or the head of the body of which is retained in grooves presented for this purpose by the edges of said beam.

Un résultat que l'invention vise è obtenir est une poutrelle autoportante nervurée avec laquelle est aisée une liaison mécanique entre mur et poutrelle. One result which the invention aims to obtain is a ribbed self-supporting beam with which a mechanical connection between wall and beam is easy.

Est également un résultat de l'invention, de telles poutrelles permettant entre elles la pose d'un joint bien ancré, de section importante et donc résistant à des sollicitations importantes. Is also a result of the invention, such beams allowing between them the installation of a well anchored joint, of large section and therefore resistant to significant stresses.

A cet effet, elle a pour objet un élément du type précité notamment caractérisé en ce que, indépendamment de toute éventuelle nervure intermédiaire (3) , chaque -poutrelle (13 1') comprend au moins deux nervures latérales dont la disposition et la section sont telles que leur face latérale externe (vis, 16) est située dans le plan de juxtaposition des poutrelles qui, ainsi prennent appui l'une contre l'autre ou contre un mur par toute la surface externe de leurs nervures. To this end, it relates to an element of the aforementioned type, in particular characterized in that, independently of any possible intermediate rib (3), each -beam (13 1 ') comprises at least two lateral ribs whose arrangement and section are such that their external lateral face (screws, 16) is situated in the plane of juxtaposition of the beams which thus bear against one another or against a wall by the entire external surface of their ribs.

Elle a également pour objet les dalles réalisées avec ces poutrelles ainsi que leur procédé de fabrication et les moyens en vue de la mise en oeuvre de ce procédé. It also relates to the slabs made with these beams and their manufacturing process and the means for the implementation of this process.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annee qui représente, schématiquement
Figure 1, vus en perspective, les moyens en vue de la mise en oeuvre du procédé. The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the drawing below which schematically represents

En se reportant aux figures 5 à 7, on voit que l'élément préfabriqué (1) est une poutrelle-, qui, raidie par au moins deux nervures longitudinales (2, 3, 4) comprend une table (5) réalisant une fraction de dalle qui, longitudinalement à une dimension L qui correspond à l'une -des dimensions transversale et longitudinale de la dalle et qui transversalement à une dimension T correspondant à une fraction de l'autre dimension de ladite dalle. Referring to FIGS. 5 to 7, it can be seen that the prefabricated element (1) is a beam, which, stiffened by at least two longitudinal ribs (2, 3, 4) comprises a table (5) carrying out a fraction of slab which, longitudinally to a dimension L which corresponds to one of the transverse and longitudinal dimensions of the slab and which transversely to a dimension T corresponding to a fraction of the other dimension of said slab.

Latéralement, ces poutrelles présentent des rainures (6, 7) qui après juxtaposition des poutrelles (1, 1') réalisent ensemble entre ces poutrelles une gorge (8) dans laquelle est réalisé un joint (9). Laterally, these beams have grooves (6, 7) which after juxtaposition of the beams (1, 1 ') together produce between these beams a groove (8) in which is made a joint (9).

La gorge (8) a une forme apte à retenir ce joint qui après durcissement du matériau qui le constitue réalise un relatif clavetage des poutrelles (1, 1') entre elles.-
Le dessous de cette poutrelle peut évidemment être garni de matériau isolant (10).The groove (8) has a shape capable of retaining this seal which after hardening of the material which constitutes it makes a relative keying of the beams (1, 1 ') between them.
The underside of this beam can obviously be lined with insulating material (10).

De même, dans le bord inférieur (11) d'au moins certaines des nervures longitudinales (2, 3, 4) peut être prévu au moins un tasseau (12) en vue de la fixation du plafond ou de ses supports.  Similarly, in the lower edge (11) of at least some of the longitudinal ribs (2, 3, 4) may be provided at least one cleat (12) for the purpose of fixing the ceiling or its supports.

Ev idemment, dans leur table (5) et dans leurs nervures (2, 3, 4), ces poutrelles comportent des armatures (13, 14) appropriées. Obviously, in their table (5) and in their ribs (2, 3, 4), these beams have appropriate frames (13, 14).

Selon une caractéristique essentielle de l'invention, indépendamment de toute éventuelle nervure intermédiaire (3), chaque poutrelle (1, 1') comprend au moins deux nervures latérales dont la disposition et la section sont telles que leur face latérale externe (15, 16) est située dans le plan de juxtaposition des poutrelles qui, ainsi prennent appui l'une sur l'autre ou contre un mur par toute la surface externe de leurs nervures. According to an essential characteristic of the invention, independently of any possible intermediate rib (3), each beam (1, 1 ') comprises at least two lateral ribs whose arrangement and section are such that their external lateral face (15, 16 ) is located in the juxtaposition plane of the beams which, thus bear one on the other or against a wall by the entire outer surface of their ribs.

Cette situation des nervures latérales (2, 4) par rapport aux bords de la table (5) confère aux poutrelles une section non plus en Té mais en U inversé; éventuellement entrecoupé de- nervures intermédiaires (3). This situation of the lateral ribs (2, 4) relative to the edges of the table (5) gives the beams a section no longer in Tee but in inverted U; possibly interspersed with intermediate ribs (3).

Selon une autre caractéristique de l'invention, les nervures longitudinales (2, 3, 4) sont reliées entre elles par des nervures transversales (17, 18, 19). According to another characteristic of the invention, the longitudinal ribs (2, 3, 4) are interconnected by transverse ribs (17, 18, 19).

Elles comprennent au moins deux nervures transversales (17, 19) disposées chacune à l'une des extrémités de ces poutrelles pour leur offrir un large appui sur ou contre les murs porteurs (non représentés). They comprise at least two transverse ribs (17, 19) each arranged at one of the ends of these beams to offer them a large support on or against the load-bearing walls (not shown).

Dans le cas où le dessous des poutrelles est garni de matériau isolant (10), les nervures tranversales externes (17, 19) auront une hauteur suffisante pour que leur champs inférieur reste apparent. In the case where the underside of the beams is lined with insulating material (10), the external transverse ribs (17, 19) will have a sufficient height so that their lower field remains visible.

Grâce è ces nervures latérales (2, 4) et extrêmes (17, 19), les poutrelles peuvent alors aisément etre reliées mécaniquement aux murs ou poutrelles qu'elles jouxtent, par exemple par boulonnage ou des rails du genre de ceux connus sous la marque "Halfen". A cet effet, et/ou pour des passages de cables ou tuyaux, les nervures peuvent présenter des perçages (non représentés). Thanks to these lateral (2, 4) and extreme (17, 19) ribs, the beams can then easily be mechanically connected to the walls or beams which they adjoin, for example by bolting or rails of the kind of those known under the brand. "Halfen". To this end, and / or for cable or pipe passages, the ribs may have holes (not shown).

Selon une caractéristique de l'invention, les rainures (6, 7) réalisent les gorges (8) du clavetage (9) s'étendent non seulement sur toute l'épaisseur de la table (5) de la poutrelle mais encore sur une partie de la hauteur des nervures latérales. Du fait de sa hauteur, le clavetage d'une part, acquiert une section plus importante donc plus résistante et d'autre part, peut présenter, non seulement à sa base, mais aussi à au moins un niveau supérieur, des renflements (20, 21, 22, 23) répartissant en hauteur les zones de résistance à l'arrachement. According to a characteristic of the invention, the grooves (6, 7) provide the grooves (8) of the keying (9) extend not only over the entire thickness of the table (5) of the beam but also over a part the height of the side ribs. Because of its height, the keying on the one hand, acquires a larger section therefore more resistant and on the other hand, can present, not only at its base, but also at at least a higher level, bulges (20, 21, 22, 23) distributing the tear resistance zones in height.

En vue de la fabrication de ces poutrelles, on réalise un moufle, ce pourquoi, tout d'abord, à la périphérie d'un fond (24) présentant des saillies (25, 26, 27, 28) réservant les creux délimités par les nervures (2, 3, 4), on dispose quatre parois latérales dont deux longitudinales (29, 30) et deux transversales (31, 32) en situant leurs faces internes dans les plans des faces externes des nervures latérales (2, 4) et extrêmes (17, 19) puis, à une hauteur convenable, on fixe sur chacune des parois longitudinales (29, 30), on fixe un négatif (33, 34) des rainures (6, 7) à réaliser dans les faces latérales de la poutrelle, tandis que par dessus et entre les saillies (25 à 28) du fond, on place les armatures nécessaires (13, 14) que l'on positionne par rapport aux parois latérales et enfin, on coule et on laisse prendre le béton qui constitue la poutrelle (1, 1') avant de la démouler. For the production of these beams, a muffle is produced, which is why, first of all, at the periphery of a bottom (24) having projections (25, 26, 27, 28) reserving the hollows delimited by the ribs (2, 3, 4), there are four lateral walls, two longitudinal (29, 30) and two transverse (31, 32) by locating their internal faces in the planes of the external faces of the lateral ribs (2, 4) and extremes (17, 19) then, at a suitable height, one fixes on each of the longitudinal walls (29, 30), one fixes a negative (33, 34) of the grooves (6, 7) to be produced in the lateral faces of the beam, while above and between the projections (25 to 28) at the bottom, the necessary reinforcements (13, 14) are placed which are positioned in relation to the side walls and finally, they are poured and the concrete which sets constitutes the beam (1, 1 ') before removing it from the mold.

Les éléments de ce moule (35) constituent les moyens en vue de la mise en oeuvre du procédé de fabrication, objet de l'invention. The elements of this mold (35) constitute the means for the implementation of the manufacturing process, object of the invention.

Les saillies (25 à 28) peuvent être solidaires du fond ou être amovibles. Lorsqu'elles sont amovibles, le fond peut être réalisé par n importe quel fond plan (36) tel celui de l'aire de préfabrication
Les saillies, voire même le fond, sont en matériau de coffrage, soit réutilisable tel de la tole ou du bois, soit perdu, tel de l'isolant thermique (10) comme par exemple polystyrène expansé.The projections (25 to 28) may be integral with the bottom or be removable. When they are removable, the bottom can be made by any flat bottom (36) such as that of the prefabrication area
The projections, or even the bottom, are made of formwork material, either reusable such as sheet metal or wood, or lost, such as thermal insulation (10) such as for example expanded polystyrene.

Les parois latérales (29 à 32) sont en toute hypothèse en matériau de coffrage réutilisable tel le bois ou la tole. Elles comprennent avantageusement des moyens (37, 38, 39) de positionnement des armatures (13, 14) tels par exemple, des fentes.  The side walls (29 to 32) are in any case made of reusable formwork material such as wood or sheet metal. They advantageously include means (37, 38, 39) for positioning the frames (13, 14) such as, for example, slots.
