Abstract

The anchor rod (2) has a lateral bulge or projection (5) running along its length and constituting an anchoring element for providing anchoring in a direction perpendicular to the longitudinal direction of the rod (2). Such an anchor is applicable to lifting and handling panels, in particular panels made of reinforced concrete.

Description

La présente invention a pour objet une ancre pour matériaux durcissables et notamment pour du béton, introduite dans un moule avant coulée du matériaux, et destinée en particulier, mais non exclusivement, à la manutention de panneaux minces de béton armé, tels que ceux qui sont employés dans les constructions préfabriquées.The present invention relates to an anchor for hardenable materials and in particular for concrete, introduced into a mold before casting of the materials, and intended in particular, but not exclusively, for handling thin panels of reinforced concrete, such as those which are employed in prefabricated constructions.

De telles ancres sont bien connues, une des deux extrémités d'une tige, permettant une liaison mécanique avec le crochet d'un engin de levage alors que le reste de l'ancre désigné dans la technique par tige, pour la partie longitudinale, et pied, pour l'autre extrêmité, est intégré dans le matériau durcissable, lors de la coulée.Such anchors are well known, one of the two ends of a rod, allowing a mechanical connection with the hook of a lifting machine while the rest of the anchor designated in the technique by rod, for the longitudinal part, and foot, for the other end, is integrated in the hardenable material, during casting.

Une ancre d'un premier type connu comprend une extrémité de forme générale cylindrique, à partir de laquelle s'étend une tige également cylindrique terminée par un pied de diamètre supérieur au diamètre de la tige. Lorsque un effort de traction est exercé sur cet insert, le pied de l'ancre exerce sur le béton se trouvant au-dessus de lui un effort de compression. C'est-à-dire que l'effort de traction est reporté sur le pied, la forme du pied déterminant un cône d'arrachement ou de rupture.An anchor of a first known type comprises a generally cylindrical end, from which extends an equally cylindrical rod terminated by a foot with a diameter greater than the diameter of the rod. When a tensile force is exerted on this insert, the foot of the anchor exerts on the concrete above it a compression force. That is to say that the tensile force is transferred to the foot, the shape of the foot determining a tearing or breaking cone.

Il est également connu de prévoir au voisinage du pied, un oeil permettant le passage d'une armature ou fer de renfort à l'intérieur de l'ancre. Par cette disposition, est établie une solidarisation entre l'ancre et une armature ou fer de renfort passant à travers l'oeil du pied de l'ancre. Dans ce cas, le report de l'effort de traction sur la masse du panneau résulte en définitive de l'adhérence des armatures à l'intérieur du panneau.It is also known to provide in the vicinity of the foot, an eye allowing the passage of a reinforcement or reinforcing iron inside the anchor. By this arrangement, a connection is established between the anchor and a reinforcement or reinforcing iron passing through the eye of the foot of the anchor. In this case, the transfer of the tensile force to the mass of the panel ultimately results from the adhesion of the reinforcements inside the panel.

D'autres ancres sont égalements connues et utilisées et, en particulier, les ancres dites "à queue de carpe" dont la tige plate se termine par deux parties divergentes permettant de réaliser un scellement. La tige, en forme de plaque, est terminée à sa partie supérieure par un trou permettant l'introduction d'un crochet de levage ou encore, par une tige filetée ou un tube taraudé.Other anchors are also known and used and, in particular, the so-called "carp tail" anchors whose flat rod ends in two divergent parts making it possible to seal. The rod, in the form of a plate, is finished at its upper part by a hole allowing the introduction of a lifting hook or even by a threaded rod or a tapped tube.

Les ancrages connus permettent d'effectuer dans des conditions convenables le levage des panneaux lorsque la force de levage s'exerce dans la direction longitudinale de l'ancre. Par contre, lorsque la force appliquée sur le panneau n'est plus dans cette direction, il arrive que celle-ci fléchisse, ce qui détériore le béton, encore en partie frais, lorsque l'épaisseur du béton au-dessus de l'ancre est insuffisante. Il est donc nécessaire dans un tel cas de renforcer, d'une part la résistance à la flexion de l'ancre et, d'autre part l'élément de béton autour de l'ancre pour qu'il puisse résister à des efforts latéraux, efforts qui se produisent par exemple lorsque le panneau coulé en position horizontale doit être amené, en vue de son séchage, en position verticale.The known anchors allow the panels to be lifted under suitable conditions when the lifting force is exerted in the longitudinal direction of the anchor. On the other hand, when the force applied to the panel is no longer in this direction, it happens that it bends, which deteriorates the concrete, still partly fresh, when the thickness of the concrete above the anchor is insufficient. It is therefore necessary in such a case to strengthen, on the one hand the flexural strength of the anchor and, on the other hand the concrete element around the anchor so that it can withstand lateral forces. , forces which occur for example when the cast panel in a horizontal position must be brought, for drying, in a vertical position.

Des ancres présentant des éléments en saillie sur leur tige sont déjà connues.Anchors with elements projecting from their rod are already known.

D D - A - 96 095 se rapporte à une pièce permettant de réaliser une fixation rapide à l'intérieur d'une douille noyée dans le béton et présentant un pied et une saillie située à la moitié de la hauteur de la tige, la fixation étant réalisée en faisant tourner la pièce d'un demi tour.DD - A - 96 095 relates to a part enabling rapid fixing to be carried out inside a socket embedded in concrete and having a foot and a projection situated at half the height of the rod, the fixing being made by rotating the part half a turn.

EP - A - 0 211 256 prévoit de fixer dans une ancre plate un pied perpendiculaire à la direction de la tige.EP - A - 0 211 256 plans to fix in a flat anchor a foot perpendicular to the direction of the rod.

Ces documents ne visent qu'à améliorer la qualité de l'ancrage dans la direction de levage.These documents are only intended to improve the quality of the anchorage in the lifting direction.

AT - B - 183 553 concerne une douille, qui est rapportée sur un fer de renfort, destinée à être intégrée dans un panneau mince. Mais, la solution proposée dans ce document consiste à élargir très fortement la douille dans un plan perpendiculaire à la direction de relevage.AT - B - 183 553 relates to a socket, which is attached to a reinforcing iron, intended to be integrated into a thin panel. However, the solution proposed in this document consists in greatly expanding the bush in a plane perpendicular to the lifting direction.

Cette solution conduit à augmenter exagérément les dimensions de la pièce d'ancrage et par suite son coût. De plus, le volume du béton est réduit autour de l'ancrage.This solution leads to an excessive increase in the dimensions of the anchor piece and consequently in its cost. In addition, the volume of concrete is reduced around the anchor.

La présente invention a pour objet de proposer une ancre permettant une application d'efforts latéraux sur le panneau. La présente invention peut être appliquée à toutes les ancres de type connu, à tige cylindrique , creuse ou pleine, ou plate et à tête et pied quelconques. Elle permet, d'une manière générale, d'augmenter la résistance à la traction des ancres par une meilleure répartition des efforts dans une plus grande masse de béton, pour éliminer les surcharges locales.The object of the present invention is to provide an anchor enabling lateral forces to be applied to the panel. The present invention can be applied to all anchors of known type, with cylindrical, hollow or solid rod, or flat and with any head and foot. It allows, in general, to increase the tensile strength of anchors by a better distribution of forces in a larger mass of concrete, to eliminate local overloads.

Selon la présente invention, l'ancre de levage et de relevage, notamment panneau de béton armé, fixée à demeure dans le panneau par coulée du béton comprenant une extrémité pouvant coopérer avec un engin de levage et une tige s'étendant dans une direction longitudinale à partir de l'extrémité, jusqu'à un pied de forme quelconque, est caractérisée en ce que, au moins un élément latéral d'ancrage fait saillie au voisinage de l'extrémité à partir de la tige en définissant un cône d'arrachement (7) ayant un axe orienté en direction de la surface latérale du panneau.According to the present invention, the lifting and lifting anchor, in particular a reinforced concrete panel, fixed permanently in the panel by pouring concrete comprising an end which can cooperate with a lifting machine and a rod extending in a longitudinal direction. from the end, to a foot of any shape, is characterized in that at least one lateral anchoring element projects in the vicinity of the end from the rod, defining a taper cone (7) having an axis oriented towards the side surface of the panel.

Alors que dans les pièces d'ancrages connues l'ancre était conçue pour résister à l'application d'une force unidirectionnelle s'exercant selon la direction longitudinale de celle-ci, l'ancre selon l'invention présente une résistance accrue, dans une direction transversale, perpendiculaire à la direction longitudinale de l'ancre. Les éléments d'ancrage latéral accroissent la rigidité de la tige en direction transversale.Whereas in known anchorages, the anchor was designed to resist the application of a unidirectional force exerted in the longitudinal direction thereof, the anchor according to the invention has increased resistance, in a transverse direction, perpendicular to the longitudinal direction of the anchor. The lateral anchoring elements increase the rigidity of the rod in the transverse direction.

D'une manière générale, l'élément d'ancrage latéral constitue une protubérance sur la tige permettant éventuellement d'éloigner les points de contact des fers de renfort hors du plan médian du panneau c'est-à-dire en-dehors de la direction longitudinale de l'ancre, lorsqu'une liaison avec les fers est souhaitable.In general, the lateral anchoring element constitutes a protuberance on the rod possibly allowing the contact points of the reinforcement bars to be moved away from the median plane of the panel, that is to say outside the longitudinal direction of the anchor, when a link with the irons is desirable.

Sur la majorité des figures, les pieds de l'ancre n'ont pas été représentés puisque, comme indiqué précédemment ils peuvent être quelconques.In the majority of the figures, the feet of the anchor have not been shown since, as indicated previously, they may be any.

Comme indiqué précédemment, il existe de nombreux cas dans lesquels les ancres doivent soutenir des efforts non longitudinaux. Un premier exemple est donné sur la Figure 1 qui représente un panneau épais pour lequel l'utilisateur a interdit que des points d'ancrage soient prévus dans la face supérieure. Dans ce cas, le levage doit être effectué à partir de points d'ancrage latéraux. Les forces F1 appliquées sur les ancres sont donc perpendiculaires à la direction des ancres (non représentées). Si l'épaisseur "1" est insuffisante, les ancres peuvent se déformer et détériorer le béton. Un autre exemple d'application de l'invention est représenté sur la figure la. Il s'agit dans ce cas de relever un panneau mince, c'est à dire de le faire passer de la position horizontale représentée, à la position verticale, par pivotement de 90°, par application sur les ancres d'une force F2. A nouveau, si l'épaisseur "1" du béton au-dessus de l'ancre est insuffisante, l'ancre va se déformer et blesser le béton. Les panneaux sont également soumis à des efforts latéraux lorsque, suspendus à un engin de levage, ils subissent les effets du vent. La présente invention permet de renforcer les ancres et de transporter des panneaux, alors que l'épaisseur "1" est insuffisante avec les ancres traditionnelles. Pour celà, la résistance de chaque ancre est augmentée dans le plan "P" de la Fig.1, dans lequel sont appliquées les forces F1 et F2, quel que soit l'angle existant entre la direction longitudinale ce l'ancre et la direction de la force extérieure.As indicated previously, there are many cases in which the anchors must support non-longitudinal forces. A first example is given in Figure 1 which represents a thick panel for which the user has prohibited that anchor points are provided in the upper face. In this case, lifting must be carried out from lateral anchor points. The forces F1 applied to the anchors are therefore perpendicular to the direction of the anchors (not shown). If the thickness "1" is insufficient, the anchors can deform and deteriorate the concrete. Another example of application of the invention is shown in Figure la. In this case, it is a question of raising a thin panel, that is to say of passing it from the horizontal position shown, to the vertical position, by pivoting through 90 °, by applying to the anchors a force F2. Again, if the thickness "1" of the concrete above the anchor is insufficient, the anchor will warp and injure the concrete. The panels are also subjected to lateral forces when, suspended from a lifting device, they are affected by the wind. The present invention makes it possible to reinforce the anchors and to transport panels, when the thickness "1" is insufficient with traditional anchors. For this, the resistance of each anchor is increased in the plane "P" of Fig.1, in which the forces F1 and F2 are applied, whatever the angle between the longitudinal direction of the anchor and the direction of external force.

Un premier mode de réalisation de l'invention est représenté sur les figures 2,2a. Dans cet exemple, l'ancre est à tête 3 et à tige 2 cylindriques, le pied d'ancrage (non représenté) pouvant être quelconque. Conformément à l'invention, un pied latéral 5 est disposé parallèlement à la tige 2 de l'ancre. Le pied latéral détermine un cône d'arrachement 7 dont les limites sont tracées en pointillés. La périphérie du cône 7 apparaît plus clairement sur la Fig. 2a. Elle présente une forme circulaire. De préférence, l'insert ou pied latéral 5 est disposé le plus près possible de la tête 3.A first embodiment of the invention is shown in Figures 2.2a. In this example, the anchor has a head 3 and a cylindrical rod 2, the anchoring foot (not shown) being any. According to the invention, a lateral foot 5 is arranged parallel to the rod 2 of the anchor. The lateral foot determines a tearing cone 7 the limits of which are drawn in dotted lines. The periphery of the cone 7 appears more clearly in FIG. 2a. It has a circular shape. Preferably, the lateral insert or foot 5 is arranged as close as possible to the head 3.

Etant donné que l'insert latéral 5 est proche de la tête 3, le cône de rupture est coupé par la ligne 8 (comme représenté sur la figure 2a), constituant le bord du panneau, de sorte que la résistance du cône, de béton qui est proportionnelle au volume de celui-ci, est relativement faible. Aussi, selon une caractéristique de l'invention, l'élément d'ancrage 5 peut présenter un axe de symétrie incliné par rapport à la surface latérale du panneau. Comme cela apparaît sur la figure 3a, la périphérie du cône 7 prend une forme elliptique. Son volume est beaucoup plus important et par suite la résistance est également plus importante.Since the lateral insert 5 is close to the head 3, the rupture cone is cut by the line 8 (as shown in FIG. 2a), constituting the edge of the panel, so that the strength of the cone, of concrete which is proportional to the volume thereof, is relatively small. Also, according to a characteristic of the invention, the anchoring element 5 may have an axis of symmetry inclined relative to the lateral surface of the panel. As shown in Figure 3a, the periphery of the cone 7 takes an elliptical shape. Its volume is much greater and therefore the resistance is also greater.

Dans les exemples précédents représentés, l'élément latéral d'ancrage était constitué par une pièce cylindroconique. Il est également possible, afin d'augmenter la rigidité d'une tige cylindrique, de prévoir sur celle-ci une excroissance 5 telle que celle qui est représentée sur la figure 4 qui est une coupe verticale de l'extrêmité supérieure d'une ancre à tête 3 et tige 2, de formes générales cylindriques. Comme cela apparaît sur la figure 4a, l'épaisseur de la tige 2 est augmentée dans la direction d'application de la force latérale dans la réservation 6, mais elle reste constante dans la direction perpendiculaire. La rigidité de la tige 2, est ainsi augmentée, et il est possible de faire basculer les panneaux de la position horizontale à la position verticale dans laquelle l'ancre travaille normalement. La rigidité de la tige de l'ancre a ainsi été augmentée transversalement sans qu'il y ait une diminution notable de l'épaisseur du béton.In the previous examples shown, the lateral anchoring element was constituted by a cylindrical-conical piece. It is also possible, in order to increase the rigidity of a cylindrical rod, to provide thereon a protrusion 5 such as that which is represented in FIG. 4 which is a vertical section of the upper end of an anchor with head 3 and rod 2, of generally cylindrical shapes. As shown in Figure 4a, the thickness of the rod 2 is increased in the direction of application of the lateral force in the reservation 6, but it remains constant in the perpendicular direction. The rigidity of the rod 2 is thus increased, and it is possible to tilt the panels from the horizontal position to the vertical position in which the anchor works normally. The rigidity of the anchor rod was thus increased transversely without there being a noticeable reduction in the thickness of the concrete.

Les figures 5 et 5a représentent une ancre à tige cylindrique 2 et à tête cylindrique 3 présentant une excroissance 5a et, opposé à celle-ci par rapport à la tige, un élément d'ancrage latéral 5. Un fer de renfort 4 vient prendre appui sur l'excroissance 5a comme celà sera décrit ultérieurement et l'insert latéral 5 détermine un cône d'arrachement 7.Une ancre, telle que celle qui est représentée sur les figures 5 et 5a, peut travailler simultanément à la compression par la pièce 5 et en adhérence par le passage d'un fer 4 sur l'excroissance ou renflement 5a.Figures 5 and 5a show an anchor with a cylindrical rod 2 and a cylindrical head 3 having a protrusion 5a and, opposite the latter relative to the rod, a lateral anchoring element 5. A reinforcing iron 4 comes to bear on the protrusion 5a as will be described later and the lateral insert 5 determines a taper cone 7. An anchor, such as that which is represented in FIGS. 5 and 5a, can work simultaneously with compression by the part 5 and in adhesion by the passage of an iron 4 on the protuberance or bulge 5a.

Les figures 6, 6a, 7 et 8, représentent une autre réalisation avec une ancre à tige plate ou cylindrique 2 à tête cylindrique 3 et une protubérance longitudinale 5a. Cette protubérance peut recevoir des fers de renfort 4, soit à l'intérieur d'un ou plusieurs trous 11 prévus dans la protubérance 5a (figure 7), soit à l'intérieur des rainures 12 formées dans ladite protubérance 5a (figure 8).Figures 6, 6a, 7 and 8 show another embodiment with an anchor with a flat or cylindrical rod 2 with a cylindrical head 3 and a longitudinal protuberance 5a. This protuberance can receive reinforcing bars 4, either inside one or more holes 11 provided in the protuberance 5a (FIG. 7), or inside the grooves 12 formed in said protuberance 5a (FIG. 8).

Les figures 9 et 9a, représentent une ancre à tige plate 2 en vue de face et en vue par-dessus dont la tête 3 présente un orifice permettant de passer un anneau de levage. Latéralement à la direction longitudinale de la plaque 2 est formée ou rapportée une pièce cylindrique d'ancrage 5 en forme de disque. Comme précédemment, cette pièce travaille à la compression et l'extrémité de la tige 2 (non représentée) peut être quelconque et, par exemple, à queue de carpe.Figures 9 and 9a show an anchor with a flat rod 2 in front view and in view from above, the head 3 of which has an orifice allowing a lifting ring to pass. Lateral to the longitudinal direction of the plate 2 is formed or attached a cylindrical anchoring part 5 in the form of a disc. As before, this part works under compression and the end of the rod 2 (not shown) can be arbitrary and, for example, with a carp tail.

Les figures 10 , 10a, et 10b représentent une ancre à douille taraudée 13 à éléments d'ancrage latéraux 5. A l'intérieur de l'ancre peut venir se fixer par vissage une pièce de manutention (non représentée). Comme cela apparaît sur la figure 10a, les éléments latéraux 5 font saillie de part et d'autre de la douille 13. Ils peuvent être situés à un endroit quelconque sur la longueur de la douille.Figures 10, 10a, and 10b show an anchor with threaded sleeve 13 with lateral anchoring elements 5. Inside the anchor can be fixed by screwing a handling part (not shown). As shown in FIG. 10a, the lateral elements 5 protrude on either side of the sleeve 13. They can be located anywhere along the length of the sleeve.

Les figures 11 et 11a représentent également une ancre plate dont l'élément d'ancrage latéral 5 s'étend sur sensiblement toute la longueur de l'ancre. Et il est ainsi possible de manutentionner les panneaux, dans lesquels l'ancre est incluse, dans une direction perpendiculaire à la direction longitudinale de l'ancre.Figures 11 and 11a also show a flat anchor whose lateral anchoring element 5 extends over substantially the entire length of the anchor. And it is thus possible to handle the panels, in which the anchor is included, in a direction perpendicular to the longitudinal direction of the anchor.

Dans les exemples qui viennent d'être donnés, les éléments latéraux d'ancrage sont intégrés à l'ancre lors de la fabrication. C'est-à-dire que l'ancre est efficace dans sa direction longitudinale, comme les ancres traditionnelles, mais également dans une direction perpendiculaire à cette direction, dans le plan d'application de la force de relevage.In the examples which have just been given, the lateral anchoring elements are integrated into the anchor during manufacture. That is to say that the anchor is effective in its longitudinal direction, like traditional anchors, but also in a direction perpendicular to this direction, in the plane of application of the lifting force.

Mais, les ancres et leurs éléments d'ancrage latéral doivent impérativement être convenablement positionnées à l'intérieur du moule pour pouvoir résister aux efforts latéraux. Afin d'éviter des erreurs de montage dans le moule, il est également possible de prévoir une structure symétrique des éléments d'ancrage latéral tels que ceux qui sont représentés sur les figures 12 et 13.However, the anchors and their lateral anchoring elements must imperatively be properly positioned inside the mold in order to be able to resist lateral forces. In order to avoid assembly errors in the mold, it is also possible to provide a structure symmetrical lateral anchoring elements such as those shown in FIGS. 12 and 13.

Sur les figures 12 et 12a, la tige 2 présente également des excroissances 14 latérales sur lesquelles sont formées deux pièces 15 , la pièce 15 présentant des rainures 12 de passage des fers de renfort. Cette pièce peut être obtenue directement par forgeage. Dans l'exemple représenté, la tête 3 est cylindrique, mais elle peut être plate ou constituée par une douille filetée.In FIGS. 12 and 12a, the rod 2 also has lateral protuberances 14 on which two parts 15 are formed, the part 15 having grooves 12 for passage of the reinforcement bars. This part can be obtained directly by forging. In the example shown, the head 3 is cylindrical, but it can be flat or constituted by a threaded bush.

Une telle ancre présente l'avantage de pouvoir manutentionner des panneaux dans deux directions opposées par rapport à la direction longitudinale de l'ancre et, en particulier, permettent de retourner complètement un panneau.Such an anchor has the advantage of being able to handle panels in two opposite directions with respect to the longitudinal direction of the anchor and, in particular, allow a panel to be completely turned over.

Dans les exemples qui viennent d'être donnés, les ancres sont monobloc. Il est également possible de mettre en oeuvre l'invention à l'aide de pièces rapportées qui peuvent être solidarisées des ancres classiques par friction, soudure, brasure etc....In the examples which have just been given, the anchors are in one piece. It is also possible to implement the invention using attached parts which can be joined to the conventional anchors by friction, welding, brazing, etc.

La pièce 16 représentée sur les figures 13, 13a et 13b, est plus particulièrement conçue pour être glissée sur une ancre à douille. Elle présente un orifice central 17 se glissant sur la tige d'une ancre et des rainures 12 de maintien de fers de renfort, les pieds 5 constituent des éléments d'ancrage latéral ce qui permet d'utiliser une telle ancre en compression, c'est-à-dire sans liaison avec les armatures.The part 16 shown in FIGS. 13, 13a and 13b, is more particularly designed to be slid over a socket anchor. It has a sliding central hole 17 on the rod of an anchor and grooves 12 for holding reinforcement bars, the feet 5 constitute lateral anchoring elements which makes it possible to use such an anchor in compression, that is to say without connection with the frames.

Les Figures 14 et 14a, représentent une pièce 20 rapportable sur une ancre à tige plate de laquelle elle peut être solidarisée par tout moyen. Elle se présente sous la forme d'un "U" ou étrier dont l'ouverture interne 18 s'applique contre les côtés de la tige. Les pieds 19 de la pièce 20 sont, de préférence inclinés par rapport à l'horizontale comme dans le mode de réalisation de la Figure 3, afin d'augmenter le volume du cône de rupture. A la partie supérieure de la pièce 20 est formée une rainure 12 permettant d'assujettir un fer de renfort (non représenté).Figures 14 and 14a show a part 20 which can be attached to an anchor with a flat rod from which it can be secured by any means. It is in the form of a "U" or stirrup whose internal opening 18 is applied against the sides of the rod. The feet 19 of the part 20 are preferably inclined relative to the horizontal as in the embodiment of Figure 3, in order to increase the volume of the rupture cone. At the upper part of the part 20 is formed a groove 12 for securing a reinforcing iron (not shown).
