Abstract

According to the device of the invention, in order to counter the consecutive disturbances in the disaggregation of the concrete due to Poisson's ratio, the compressed bars are banded by a continuous piece of steel wound into coils (3) that are connected via straight segments (2). The ladders (1), which constitute the basic three-dimensional structural elements, have simple triangular, rectangular, or polygonal cross-sections. Said basic units can be assembled either by bars or, in order to increase the ultimate strength, by ladders (5) having axes that intersect the mid-plane.

Description

CAGE d'ARMATURES TISSEES POUR OUVRAGES EN BETON  CAGE OF WELDED FRAME FOR CONCRETE WORKS
Et PROCEDES DE FABRICATION  AND METHODS OF MANUFACTURE
Le procédé décrit s'applique à la réalisation du renforcement d'ouvrages en béton que ceux-ci soient préfabriqués, ou plus généralement remplis sur site de construction. The method described applies to the realization of reinforcement of concrete structures that they are prefabricated, or more generally filled on construction site.
Le béton est un excellent matériau qui accepte des contraintes de compression élevées. Par contre le béton se caractérise par des contraintes admissibles de traction très faibles (10% des contraintes admissibles en compression). C'est la raison pour laquelle un ouvrage en béton est toujours armé au moins en zone tendue afin de pallier les reprises des contraintes de traction du béton de faible valeur. Il est cependant difficile, dans des ouvrages verticaux particulièrement, de déterminer où se situera la zone tendue. Celle-ci dépend de la position des charges par rapport à la fibre neutre appliquées dans un cadre statique mais aussi dynamique (en cas de charges accidentelles, séisme par exemple). Ainsi, dans la majorité des cas et particulièrement pour les bâtiments réalisés en zone sismique, les ouvrages sont prévus avec un ferraillage extérieur et intérieur. Concrete is an excellent material that accepts high compressive stresses. On the other hand, concrete is characterized by very low allowable tensile stresses (10% of the allowable compressive stresses). This is the reason why a concrete structure is always reinforced at least in tensioned zone in order to compensate for the recovery of tensile stresses of low value concrete. However, it is difficult in particular vertical structures to determine where the tense area will be located. This depends on the position of the charges relative to the neutral fiber applied in a static frame but also dynamic (in case of accidental loads, earthquake for example). Thus, in the majority of cases and particularly for buildings built in seismic zones, the structures are provided with external and internal reinforcement.
Dans le cas des poteaux ou des poutres particulièrement, lorsque l'ouvrage est soumis à une compression importante, par application du coefficient de POISSON, le béton se ruine sous l'effet de dépassement de la contrainte transversale. Pour pallier ce phénomène on dispose des cadres qui ceinturent les armatures principales et évitent la poussée au vide des aciers principaux. Ces dispositifs (cadres) frettent la structure d'aciers principaux et confinent le béton situé à l'intérieur de ces « cadres frettes ». Dans le cas de réalisation de voiles ou d'ouvrages de grande dimension par rapport à l'épaisseur, traditionnellement les armatures du béton sont sous forme de cage constituée par deux treillis soudés maintenus à distance par des écarteurs. Ces derniers sont soit de section triangulaire soit à profil ondulé. Les treillis sont rapportés sur les écarteurs et fixés à ces derniers par ligatures ou soudage. Dans ces conditions on comprend aisément que les contraintes transversales admissibles de l'ouvrage sont proportionnelles à la section et à la nature des liaisons treillis avec les écarteurs. Or, les dites liaisons (soudées par points ou ligaturées) sont de faibles valeurs (1 à 2mm2) et ne permettent pas de reprendre les contraintes transversales en cas de charges importantes. C'est pourquoi, traditionnellement l'homme de l'art ajoute, en complément, des épingles dont le profil est généralement perpendiculaire aux plans des treillis, et qui relient les treillis intrados et extrados. Cette disposition est longue, consomme de l'acier afin d'assurer l'accrochage des épingles sans glissement dans le béton (en général 25 à 50 fois le diamètre des épingles), et par voies de conséquences est onéreux et non économe pour les ressources de la planète. In the case of columns or beams especially, when the structure is subjected to a large compression, by application of the coefficient of FISH, the concrete is ruined under the effect of exceeding the transverse stress. To overcome this phenomenon we have frames that surround the main frames and avoid the vacuum thrust of the main steels. These devices (frames) frite the main steel structure and contain the concrete located inside these "frets". In the case of making veils or large structures in relation to the thickness, traditionally the reinforcement of the concrete is in the form of a cage consisting of two welded mesh held at a distance by spacers. These The last ones are either triangular or corrugated. The lattices are reported on the spacers and fixed to the latter by ligatures or welding. In these conditions it is easily understood that the allowable transverse stresses of the structure are proportional to the section and the nature of the lattice connections with the spacers. However, the said bonds (spot welded or ligated) are low values (1 to 2mm 2 ) and do not allow to take the transverse stresses in case of significant loads. This is why, traditionally, those skilled in the art add, in addition, pins whose profile is generally perpendicular to the planes of the lattices, and which connect the intrados and extrados lattices. This arrangement is long, consumes steel to ensure the attachment of pins without slip in the concrete (usually 25 to 50 times the diameter of the pins), and by way of consequences is expensive and not economical for resources of the planet.
Le procédé ci-dessous revendiqué permet de pallier ces inconvénients. Un mode de mise en œuvre du procédé selon l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels : The process below claimed makes it possible to overcome these disadvantages. One embodiment of the method according to the invention will be described below, by way of nonlimiting example, with reference to the accompanying drawings in which:

Ces filants sont disposés aux sommets d'un triangle isocèle. La hauteur du dit triangle est fonction de l'épaisseur des enrobages réglementaires appliqués à l'ouvrage en béton à réaliser. Autour de ces filants est enroulé un ressort, dénommé frette 3, suivant un pas généralement constant déterminé (par exemple 20 cm). Cette frette 3 continue peut être, de pas à droite comme représentée sur la figure la, à gauche (non représenté), ou les deux (cad croisée), comme représentée sur la figure lb. Comme représenté sur le détail le de la Planche 1, afin d'optimiser la contrainte de traction dans le matériau constituant la frette 3, dans la présente invention cette dernière est constituée par des spires 3a, 3b, 3c au droit de chaque filant Haute adhérence (HA) 2a, 2b, 2c lesquelles spires sont reliées par des droites 3d, 3e, 3f. Figure 1 represents an elementary example of scale subassembly {1}. This subset {1} is composed of high adherence steels 2a, 2b, 2c. These threads are arranged at the vertices of an isosceles triangle. The height of said triangle is a function of the thickness of the regulatory coatings applied to the concrete structure to achieve. Around these threads is wound a spring, called fret 3, in a generally constant determined pitch (for example 20 cm). This hoop 3 may continue, step right as shown in Figure la, left (not shown), or both (ie cross), as shown in Figure lb. As shown in the detail of Plate 1, in order to optimize the tensile stress in the material constituting the hoop 3, in the present invention the latter is formed by turns 3a, 3b, 3c to the right of each High adherence (HA) thread 2a, 2b, 2c which turns are connected by lines 3d, 3e, 3f.
Cette disposition présente 2 avantages principaux : This provision has 2 main advantages:
• Elle ne nécessite qu'un ancrage aux extrémités et non à chaque cadre. • It only requires anchoring at the ends and not at each frame.
Ce qui optimise la quantité d'acier ;  Which optimizes the quantity of steel;
• Inclinée dans son profil droit, elle couture bien mieux la fissuration potentielle du béton aux états ultimes ;  • Inclined in its straight profile, it sews better the potential cracking of the concrete to the ultimate states;
• Lassée la frette 3, reprend les contraintes transversales sur la section totale de l'acier qui la constitue.  • Lassée the fret 3, takes the transversal stresses on the total section of the steel which constitutes it.
· Le profil de la frette 3 relie les barres longitudinales suivant des droites · The profile of the hoop 3 connects the longitudinal bars along lines
3d, 3e & 3f. Cette disposition implique un travail de l'acier en traction pure et ne provoque pas de contraintes parasites dans le béton qui seraient induites par une déformation vers un profil géodésique de la frette 3. Dans l'exemple sur les figures 2a & 2b, est représentée une cage d'armatures selon le procédé. La dite cage est constituée par une juxtaposition d'échelles {1} en disposition alternée. Les dites échelles {1} sont reliées en partie interne de la cage, c'est-à-dire à l'intérieur du triangle dont les sommets sont définis par les filants 2a, 2b et 2c des échelles {1}, par des aciers généralement en haute adhérence (HA) 4 sensiblement orthogonaux aux HA 2a, 2b & 2c des échelles. Préférentiellement, ces HA 4 sont disposés dans les boucles des frettes 3. De façon à maintenir leur position avant mise en œuvre du remplissage généralement en béton, les HA 4 sont fixés sur les échelles principales par ligatures, soudage par points ou autre dispositif (par exemple collage) qui assure une fixation suffisante pour un transport, une mise en œuvre et un remplissage sans déformation hors tolérances. Sur les figures 2a en perspective et 2b en coupe, ces échelles {1} sont disposées alternativement de façon à présenter sensiblement la même répartition d'acier en parties extérieure et intérieure. 3d, 3e & 3f. This provision involves a steel work in pure tension and does not cause stresses in the concrete that would be induced by a deformation to a geodesic profile of the hoop 3. In the example in Figures 2a & 2b, is shown a reinforcement cage according to the method. The said cage is constituted by a juxtaposition of scales {1} in alternating arrangement. Said scales {1} are connected to the inner part of the cage, that is to say within the triangle whose vertices are defined by the strands 2a, 2b and 2c of the scales {1}, by steels generally in high adhesion (HA) 4 substantially orthogonal to HA 2a, 2b & 2c scales. Preferably, these HA 4 are arranged in the loops of the hoop 3. In order to maintain their position before implementation of the generally concrete filling, the HA 4 are fixed on the main scales by ligatures, spot welding or other device (for example example gluing) which provides sufficient fixation for transport, implementation and filling without deformation out of tolerances. In Figures 2a in perspective and 2b in section, these scales {1} are arranged alternately so as to have substantially the same steel distribution in outer and inner portions.
Sur les figures 2c en perspective êt 2d en coupe les échelles {1} sont disposées dans le même sens, c'est-à-dire que la base des triangles est dans un même plan et plus généralement dans le cas d'ouvrages courbes ou à double courbure du même côté de la surface intérieure ou extérieure pour augmenter le taux d'acier du côté de la surface devant présenter la résistance à la traction ou flexion composée la plus élevée. Dans l'exemple en figure 3 on représente une disposition pertinente pour une réalisation de cage tridimensionnelle dans deux directions sensiblement orthogonales. Comme décrit précédemment les échelles principales {1} peuvent avoir leurs bases du même côté ou inversées. Les dites échelles principales sont traversées par des échelles secondaires {5} dont la hauteur est moindre que celle des échelles principales {1}. De façon à maintenir leur position avant mise en oeuvre du remplissage généralement en béton, les échelles secondaires {5} sont fixées sur les échelles principales {1} par ligatures, soudage par points ou autre dispositif qui assure une fixation suffisante pour un transport, une mise en œuvre et un remplissage sans déformation hors tolérances. Dans l'exemple représenté sur les figures 4 (vue 4a en perspective et 4d en coupe), une application particulière de cette technologie est dessinée. Dans cette application la rigidité élevée de la disposition décrite sur la figure 3 permet d'augmenter considérablement l'espacement entre les échelles principales {1} ainsi que celui entre les échelles secondaires {5}. Cet espacement peut être porté par exemple à 60cm avec des aciers HA 2a, 2b, 2c convenablement dimensionnés (HA12 pour la zone tendue par exemple). Avantageusement pour limiter la quantité de béton en zone tendue, les échelles principales {1} & secondaires {5} seront disposées bases en partie supérieure. Les aciers HA 2a des sommets inférieurs seront dimensionnés de façon à reprendre les contraintes de traction de l'ouvrage à réaliser. In Figures 2c in perspective and 2d in section the scales {1} are arranged in the same direction, that is to say that the base of the triangles is in the same plane and more generally in the case of curved structures or double curvature on the same side of the inner or outer surface to increase the surface side steel ratio to have the highest tensile strength or composite flexure. In the example in Figure 3 there is shown a relevant provision for a three-dimensional cage realization in two substantially orthogonal directions. As previously described, the main scales {1} can have their bases on the same side or inverted. The so-called main scales are traversed by secondary scales {5} whose height is less than that of the main scales {1}. In order to maintain their position before implementation of the generally concrete filling, the secondary ladders {5} are fixed on the main scales {1} by ligatures, spot welding or other device which ensures a sufficient fixation for a transport, a implementation and filling without deformation out of tolerances. In the example shown in FIGS. 4 (view 4a in perspective and 4d in section), a particular application of this technology is drawn. In this application, the high rigidity of the arrangement described in FIG. 3 makes it possible to considerably increase the spacing between the main scales {1} as well as that between the secondary scales {5}. This spacing may be brought for example to 60 cm with suitably dimensioned HA 2a, 2b, 2c steels (HA12 for the tensioned zone for example). Advantageously, to limit the amount of concrete in an extended zone, the main {1} & secondary {5} scales will be arranged in part. higher. The HA 2a steels of the lower vertices will be dimensioned so as to take up the tensile stresses of the work to be done.
Dans le cas d'un plancher, le vide parallélépipédique entre les échelles principales et secondaires peut être coffré par exemple par des hourdis 6 préférentiellement en composite mais également en toute autre matière. Avantageusement, la forme supérieure 7 des dits hourdis sera en forme de voûte afin de maintenir le béton 8 de la dalle de compression totalement comprimé. Par cette disposition avantageuse, on réduit au minimum l'utilisation du béton en zone tendue. In the case of a floor, the parallelepipedal space between the main and secondary ladders can be encased for example by slabs 6 preferably in composite but also in any other material. Advantageously, the upper form 7 of said slabs will be arched in order to maintain the concrete 8 of the compression slab completely compressed. By this advantageous arrangement, the use of concrete in a tight zone is minimized.
Dans le cas d'une toiture, ce vide peut également être occulté par des panneaux de grandes dimensions comme des panneaux photovoltaïques ou des panneaux solaires. In the case of a roof, this void can also be obscured by large panels such as photovoltaic panels or solar panels.
Dans tous les cas, l'économie réalisée en matière (béton) sur un plancher est importante (40 % par exemple). Elle se traduit par une économie financière en matière mais également de mise en œuvre. S'il s'agit d'un immeuble, cette économie qui est reproduite sur tous les étages de l'ouvrage, engendre une économie de poids propre. Cette dernière conduit à une économie substantielle au niveau des fondations. In any case, the savings in material (concrete) on a floor is important (40% for example). It translates into a financial saving in terms but also of implementation. If it is a building, this economy is reproduced on all floors of the book, generates a saving of own weight. The latter leads to substantial savings at the foundation level.
En planche 5, différentes sections sont schématisées. Une section plane en figure 5a, une section triangulaire en figure 5b, une section rectangulaire en figure 5c, une section polygonale en figure 5d. Sur ces représentations schématiques les filants 2(i) placés aux sommets de la section ont des diamètres égaux ou différents selon les contraintes auxquelles ils seront soumis. Dans les figures 5a à 5d un cercle circonscrit est défini. Ce cercle tangent par l'extérieur aux diamètres des filants a un centre qui va constituer l'axe de rotation utilisé pour la réalisation des échelles et décrit ci après et schématisé en planche 6. En planche 6, le cahier des charges pour la fabrication des échelles est illustré. Ces prescriptions permettent de réaliser les échelles {1} décrites ci-dessus par une machine qui respecte les dispositions suivantes : Les filants généralement en acier HA (2a, 2b & 2c, ou 2i) peuvent être disposés de différentes façons. Suivant une section plane comme représentée sur la figure 5a ou triangulaire comme par simplification généralement décrite et dessinée dans la présente demande et représentée en figure 5b, mais aussi suivant une section rectangulaire comme représentée sur la figure 5c ou une section octogonale comme représentée sur la figure 5d. Ces différentes sections sont simultanément mises : In plate 5, different sections are schematized. A flat section in Figure 5a, a triangular section in Figure 5b, a rectangular section in Figure 5c, a polygonal section in Figure 5d. On these schematic representations the filaments 2 (i) placed at the vertices of the section have diameters equal or different depending on the constraints to which they will be subjected. In Figures 5a to 5d a circumscribed circle is defined. This circle is tangential to the diameters of the strands at a center which will constitute the axis of rotation used for the realization of the scales and described below and shown schematically in plate 6. In plate 6, the specifications for the manufacture of scales is illustrated. These requirements make it possible to carry out the {1} scales described above by a machine which complies with the following provisions: The wire generally HA steel (2a, 2b & 2c, or 2i) can be arranged in different ways. According to a flat section as shown in FIG. 5a or triangular as a simplification generally described and drawn in the present application and shown in FIG. 5b, but also in a rectangular section as shown in FIG. 5c or an octagonal section as shown in FIG. 5d. These different sections are simultaneously put:
• en rotation suivant un axe coïncident avec le centre du cercle circonscrit tangent aux faces cylindriques externes des dits filants 2(i), • in rotation along an axis coincident with the center of the circumscribed circle tangential to the external cylindrical faces of the so-called ropes 2 (i),
• en translation suivant une direction sensiblement orthogonale à la section. La translation et la rotation sont liées de telle façon qu'à une rotation de 360° corresponde un pas de la frette 3 désirée.  • in translation in a direction substantially orthogonal to the section. The translation and the rotation are linked in such a way that at a rotation of 360 ° corresponds to a pitch of the desired hoop 3.
Un fil continu 3 est disposé sur le bâti de la machine avec les contraintes suivantes : A continuous wire 3 is disposed on the frame of the machine with the following constraints:
• L'axe de ce fil 3 est confondu sensiblement avec la tangente au cercle circonscrit de l'échelle {1} à réaliser, The axis of this wire 3 is substantially confused with the tangent to the circumscribed circle of the scale {1} to be produced,
· Le fil 3 est maintenu en traction afin de réaliser une contrainte destinée à redresser le dit fil 3. Comme il sera décrit sur la figure 6a, cette disposition est assurée par un redresseur à galet 9f. La force de serrage de ce redresseur 9f sera ajustée de façon à juste réaliser cette condition,  · The wire 3 is maintained in tension in order to achieve a stress for straightening said wire 3. As will be described in Figure 6a, this arrangement is provided by a roller rectifier 9f. The clamping force of this rectifier 9f will be adjusted to just achieve this condition,
• Le fil 3 est fixé généralement à chaque croisement avec les filants. Cette fixation peut être réalisée par soudure ou par ligature ou toute autre méthode et au moins plus d'une fois par pas.  • The wire 3 is fixed generally at each crossing with the threads. This fixation can be performed by welding or ligation or any other method and at least more than once per step.
Les figures 6a, 6b, 6c sont des vues en perspectives et la figure 6d est une vue de détail. Ces vues schématisent un exemple de machine automatique permettant de réaliser les sous-ensembles échelles {1} & {5} selon le cahier des charges ci-dessus. Sur les figures 6a, 6b & 6c on distingue en perspectives, successivement aérienne, de côté amont et côté aval, l'ensemble de la machine destinée à la fabrication des « C.A.T » qui, pour la bonne compréhension, est décrit pour exemple ci-après. Figures 6a, 6b, 6c are perspective views and Figure 6d is a detail view. These views schematize an example of an automatic machine to realize the subsets scales {1} & {5} according to the specifications above. Figures 6a, 6b and 6c are distinguished in perspective, successively aerial, upstream side and downstream side, the entire machine for the manufacture of "CAT" which, for the sake of understanding, is described for example hereinafter after.
L'ensemble châssis {9}, fixé au sol, est composé successivement des pièces suivantes : des joues 9a et 9b dont les faces principales sont verticales et maintenues parallèlement à distance par des entretoises 9c & 9'c dont le contreventement n'est pas représenté. La distance entre les faces des joues 9a & 9b sera déterminée afin de permettre la réalisation de la plus longue des échelles (par exemple 8m). The chassis assembly {9}, fixed to the ground, is successively composed of the following parts: cheeks 9a and 9b whose main faces are vertical and kept parallel at a distance by spacers 9c & 9'c whose bracing is not represent. The distance between the faces of the cheeks 9a & 9b will be determined in order to allow the realization of the longest of the scales (for example 8m).
Sur les entretoises 9c & 9'c, sont fixés par tous moyens des pièces supports 9d & 9'd. Le moyen de fixation choisi autorisera un blocage des pièces 9d après réglage horizontal de la cote « Ll » qui définit la longueur de l'échelle {1} à fabriquer. Dans les alésages des pièces supports 9d, sont positionnées des tiges crémaillères 9e. Les dites crémaillères 9 sont sensiblement orthogonales à l'axe principal du châssis {9}. Afin que l'axe amont de la frette 3 soit sensiblement coïncident avec la tangente de la spline, l'angle formé par le plan des axes des crémaillères 9e avec la face des joues des châssis 9a ou 9b est réglable. Sur la pièce support supérieure 9'd, est positionné un frein redresseur de fil 9f. Le dit redresseur 9f est muni d'un dispositif qui autorise aisément un réglage en hauteur (par exemple pignons liés en rotation et agissant sur les crémaillères 9e). On comprend aisément que, pour réaliser un enroulement croisé, des dispositifs 9'd, 9' e & 9'f sont disposés symétriquement par rapport à l'axe principal de la machine. Pour des raisons d'allégement et de bonne compréhension, ces éléments symétriques n'ont pas été représentés sur les dessins des planches 6. On the spacers 9c & 9'c, are fixed by any means support parts 9d & 9'd. The chosen fastening means will allow a blocking of parts 9d after horizontal adjustment of the dimension "L1" which defines the length of the scale {1} to manufacture. In the bores of the support parts 9d, 9e rack stems are positioned. The said racks 9 are substantially orthogonal to the main axis of the chassis {9}. So that the upstream axis of the hoop 3 is substantially coincident with the tangent of the spline, the angle formed by the plane of the axes of the racks 9e with the face of the cheeks of the chassis 9a or 9b is adjustable. On the upper support part 9'd, is positioned a thread straightening brake 9f. The said rectifier 9f is provided with a device that easily allows a height adjustment (for example pinions linked in rotation and acting on the racks 9e). It is easily understood that in order to produce a cross winding, devices 9'd, 9'e and 9'f are arranged symmetrically with respect to the main axis of the machine. For reasons of relief and good comprehension, these symmetrical elements have not been represented on the drawings of the boards 6.
Les joues 9a & 9b du châssis sont munies de paliers 10 dont les axes, sont situés préférentiellement sur un même cercle et équidistants (par exemple 60° comme représenté sur la figure 5b). Dans ces axes 10 sont disposés, préférentiellement alternativement, une vis mère 11 et un axe d'entraînement en rotation 12. Les dites pièces 11 & 12 étant en nombre au moins égal à trois chacune. Les vis mères 11 ont un pas fixe (par exemple 5mm). Chaque vis mère 11 est munie d'un écrou 18 mobile en translation. Le dit écrou 18, préférentiellement à billes, est solidaire d'un disque 22 dont la translation est assurée par la liaison vis mère 11 avec le dit écrou à billes 18. Chaque axe de rotation 12 entraîne en rotation un pignon fixe 13 et un pignon mobile 14. Le pignon fixe 13 entraîne en rotation une couronne 16 dans un plan fixe par rapport au bâti {9}. Le pignon mobile 14, de même module et nombre de dents que le pignon 13, est solidaire en translation du disque de translation 22. Le dit pignon mobile 14 entraîne en rotation une couronne mobile 19. Les rotations des pièces 11 sont identiques et confirmées par tous moyens non représentés (courroies crantées par exemple). Il en est de même pour les axes de rotations 12. Les rotations des pièces 11 & 12 sont différentes et réglables par un réducteur situé entre le moteur 15 et les pignons d'entraînement des vis mères 11 et axes de rotations 12. Comme décrit précédemment et représenté sur la figure 6c, complété par le détail 6d, les pignons fixes 13 entraînent en rotation un disque amont 16 situé dans un plan parallèle à la joue 9b et à distance fixe. Sur le dit disque 16 est fixé, en rotation et à distance réglable avec ce dernier, un guide 17 coaxial avec le disque 16. Le disque amont 16 est muni de passages pour les aciers amont {20}. Avantageusement le disque 16 sera muni des trous permettant la réalisation de toute une gamme d'échelles ou poutres selon le procédé. Préférentiellement, ces passages seront réalisés sur un disque secondaire 16' (non représenté par clarté) qui est centré et rapporté sur le disque 16. The cheeks 9a and 9b of the chassis are provided with bearings 10 whose axes are preferably located on the same circle and equidistant (for example 60 ° as shown in Figure 5b). In these axes 10 are arranged, preferably alternately, a mother screw 11 and a rotational drive shaft 12. The said parts 11 & 12 being in number at least equal to three each. The mother screws 11 have a fixed pitch (for example 5 mm). Each mother screw 11 is provided with a nut 18 movable in translation. Said nut 18, preferably ball, is integral with a disk 22 whose translation is provided by the mother screw connection 11 with the said ball nut 18. Each axis of rotation 12 drives in rotation a fixed pinion 13 and a pinion 14. The fixed gear 13 rotates a ring 16 in a fixed plane relative to the frame {9}. The movable pinion 14, with the same module and number of teeth as the pinion 13, is integral in translation with the translation disc 22. The said movable pinion 14 rotates a movable ring 19. The rotations of the pieces 11 are identical and confirmed by all means not shown (toothed belts for example). It is the same for the rotational axes 12. The rotations of the parts 11 & 12 are different and adjustable by a gear located between the motor 15 and the drive gears of the lead screws 11 and rotational axes 12. As previously described and shown in FIG. 6c, completed by the detail 6d, the fixed gears 13 drive in rotation an upstream disk 16 situated in a plane parallel to the cheek 9b and at a fixed distance. On said disk 16 is fixed, in rotation and remotely adjustable with the latter, a guide 17 coaxial with the disk 16. The upstream disk 16 is provided with passages for the upstream steel {20}. Advantageously, the disk 16 will be provided with holes allowing the realization of a whole range of ladders or beams according to the method. Preferably, these passages will be made on a secondary disk 16 '(not shown by clarity) which is centered and attached to the disk 16.
En partie aval un disque de translation 22 sur lequel sont fixés des écrous 18 (non représentés) préférentiellement à billes. Les dits écrous 18 sont coaxiaux avec les vis mères 11. Le disque 22 entraîne en déplacement horizontal les pignons mobiles 14 situés sur les axes 12. Coaxial avec le disque de déplacement 22 et la couronne amont 16, un disque d'entraînement en rotation 19 est disposé. Le dit disque 19 est libre en rotation par rapport au disque de translation 22 mais fixé en translation par rapport à celui-ci. In part downstream a translation disk 22 on which are fixed nuts 18 (not shown) preferentially ball. Said nuts 18 are coaxial with the mother screws 11. The disk 22 drives in horizontal displacement the movable pinions 14 located on the axes 12. Coaxial with the displacement disk 22 and the upstream ring 16, a rotating drive disc 19 is disposed. Said disc 19 is free to rotate relative to the translation disc 22 but fixed in translation relative thereto.
La couronne de rotation 19 est munie des mêmes passages de barres que ceux du disque amont 16. Lors du montage, les passages dans les disques 16 et 19 seront coaxiaux. Cette propriété sera vérifiée par exemple grâce à l'alignement de deux repères situés sur les dits disques 16 et 19. Les disques 16 & 19 sont crantés et entraînés dans la même rotation par respectivement les pignons fixes 13 & mobiles 14. Le disque 19 est par ailleurs muni de pièces de blocage (non représentées) qui assurent le blocage des aciers {20} dans leur logement. Ces pièces de blocage seront par exemple des pinces américaines à ressort. The rotating ring 19 is provided with the same bar passages as those of the upstream disk 16. During assembly, the passages in the disks 16 and 19 will be coaxial. This property will be verified for example by the alignment of two marks located on said disks 16 and 19. The disks 16 & 19 are notched and driven in the same rotation by respectively the fixed pinions 13 & mobiles 14. The disk 19 is also provided with locking pieces (not shown) which ensure the blocking of steels {20} in their housing. These locking pieces will be for example spring clips US.
Sur les planches 6 suite 2 & suite 3, le fonctionnement de la machine « CAT » peut être schématisé comme représenté dans les figures 6 e à 6h et décrit dans le principe ci-dessous : Phase 0 (début de phase) - voir figure 6 e : On the boards 6 continued 2 & 3, the operation of the machine "CAT" can be schematized as shown in Figures 6 e to 6h and described in the principle below: Phase 0 (beginning of phase) - see Figure 6 e:
Le disque mobile en translation 22 est à proximité (par exemple 50 mm) du guide avalThe moving mobile disc 22 is in the vicinity (for example 50 mm) of the downstream guide
17. Les pièces d'accrochage des barres HA sont ouvertes dans un premier temps puis refermées dans un second temps. Ce phasage permet de solidariser les barres amont {20}, qui constitueront les filants 2a, 2b & 2c de l'échelle, avec la couronne de rotation mobile 19 elle-même solidaire en translation du disque 22. Par cette disposition, à chaque tour de l'échelle le frein redresseur 9f enroule le fil frette 3 suivant la spline définie précédemment. 17. The hooking parts of the bars HA are opened at first and then closed again in a second time. This phasing makes it possible to secure the upstream bars {20}, which will constitute the ropes 2a, 2b and 2c of the scale, with the mobile rotation ring 19 itself integral in translation of the disk 22. By this arrangement, at each turn 9f of the scale winds the strand wire 3 following the spline defined above.
Phase 1 (fin de phase) & Phase 2 (découpe de l'échelle 1)- voir figures 6f & 6g : Phase 1 (end of phase) & Phase 2 (cutting of scale 1) - see figures 6f & 6g:
Le disque mobile en translation 22 touche la butée réglable 21 située sur la joue aval du châssis. Ce contact a pour effets chronologiquement de : The movable disc in translation 22 touches the adjustable stop 21 located on the downstream flange of the frame. This contact has the effects chronologically of:
1. Stopper le moteur et donc tous mouvements des pièces, 2. Libérer les fixations des filants sur le disque de rotation mobile 18 par action sur les attaches 1. Stop the engine and therefore any movements of the parts, 2. Release the fasteners of the threads on the rotating disc 18 by action on the fasteners
3. Mettre en route le dispositif de coupe situé dans le plan 21 disposé à proximité ou dans le guide 17. Phase 3 (fin de cycle) -figure 5 h : Après découpe de l'échelle {1} dans sa partie aval, les organes de serrage situés sur le disque de rotation mobile 18 étant libérés, il est possible d'évacuer l'échelle réalisée.  3. Start the cutting device located in the plane 21 disposed near or in the guide 17. Phase 3 (end of cycle) -figure 5 h: After cutting the scale {1} in its downstream part, the clamping members located on the movable rotating disc 18 being released, it is possible to evacuate the scale made.
Après cette évacuation, l'opérateur met la commande du moteur en position inverse de manière à ramener l'ensemble des disques mobiles 19 & 22 en position de la phase 0 décrite plus haut. Il est à noter que la position est préférentiellement indexée par une butée. After this evacuation, the operator puts the motor control in the opposite position so as to bring all the movable discs 19 & 22 to the position of phase 0 described above. It should be noted that the position is preferably indexed by a stop.
Les planches 7 schématisent sur différentes vues un exemple de banc de fabrication qui permet de réaliser les cages d'armatures tissées. Le dit banc pouvant être manuel ou automatisé. La figure 7a montre en perspective un banc d'assemblage nu. Dans cette figure le banc total se compose de 3 sous-ensembles : The boards 7 schematize on different views an example of a manufacturing bench that allows the realization of woven reinforcement cages. The said bench can be manual or automated. Figure 7a shows in perspective a bare assembly bench. In this figure the total bench consists of 3 subsets:

Sur ce plan 24 sont fixés en sous face et à chaque extrémité : • Pierced lights 25 whose axes are parallel to the direction of work coincides with the height of the panels to achieve. In this plane 24 are fixed under the face and at each end:
1. Des paliers 26 & 26' (non vus) coaxiaux respectivement avec un arbre 27 et 27'(non vus). Les axes des paliers 26 &26' sont parallèles entre eux et orthogonaux à la direction de travail des panneaux à réaliser. 1. Bearings 26 & 26 '(not seen) coaxial respectively with a shaft 27 and 27' (not seen). The axes of the bearings 26 & 26 'are parallel to each other and orthogonal to the direction of work of the panels to be produced.
Sur ces arbres 27 & 27' sont fixées des paliers coaxiaux avec des roues crantées 28 & 28' dont les plans médians sont :  On these shafts 27 & 27 'are fixed coaxial bearings with notched wheels 28 & 28' whose median planes are:
• Distants d'une valeur sensiblement égale à celle séparant deux axes consécutifs des lumières 25 (soit par exemple 400 mm),  • Distances of a value substantially equal to that separating two consecutive axes of the lights 25 (ie for example 400 mm),
• Sensiblement confondus avec l'axe des rainures 25.  • Noticeably mistaken for groove axis 25.
2. Entre chaque roue 28 et 28' est tendue une courroie crantée 29. Ladite courroie 29 est munie d'ergots équidistants d'une valeur égale au pas séparant deux échelles {1} (par exemple 400 mm).  2. Between each wheel 28 and 28 'is tensioned a toothed belt 29. Said belt 29 is provided with equidistant pins of a value equal to the pitch separating two scales {1} (for example 400 mm).
3. Une rampe de soudage 38 dans laquelle sont positionnées les électrodes 30 & 30' qui assureront la fixation des échelles {1} principales (de grande longueur, par exemple 6 m) sur les échelles { } secondaires (de petite longueur par exemple 3 m)  3.

B- D'une table amont {37} dont le plan médian est approximativement parallèle à celui de la table 21. Les dispositifs 24a à 29a sont préférentiellement identiques à ceux décrits dans la table 21 sans qu'il soit nécessaire de les décrire à nouveau. Cependant, signalons que les axes des rainures 25a peuvent être espacés d'une valeur différente à celle des axes des rainures 25. La table amont est en outre équipée d'un dispositif électronique ou d'une butée 34 (non représentée) qui stoppe le dispositif d'entraînement 29' lorsque l'échelle secondaire { } vient en contact avec la dite butée 34.  B- an upstream table {37} whose median plane is approximately parallel to that of the table 21. The devices 24a to 29a are preferably identical to those described in the table 21 without it being necessary to describe them again . However, it should be noted that the axes of the grooves 25a may be spaced apart from the axes of the grooves 25. The upstream table is furthermore equipped with an electronic device or a stop 34 (not shown) which stops the drive device 29 'when the secondary ladder {} comes into contact with said stop 34.
C- D'un système d'introduction {23} des échelles principales {1}.  C- An introduction system {23} of the main scales {1}.
Ce dispositif {23} relie les ensembles tables {21} & {22} à une distance qui permet le stockage d'échelles {1} jointives en quantité suffisante, fonction du pas et de la hauteur du plus grand panneau à réaliser. Le dit dispositif doit réduire au maximum les forces de frottement et est par exemple constitué, comme représenté sur la figure 7a, par des rouleaux sur paliers 39. This device {23} links the {21} & {22} table sets at a distance that allows the storage of {1} contiguous scales in sufficient quantity, depending on the not and the height of the largest panel to achieve. Said device must minimize the friction forces and is constituted for example as shown in FIG. 7a by bearing rollers 39.
Le dit dispositif est complété par le prolongement de la butée 30 non représenté et dont la face servira de butée. The said device is completed by the extension of the stop 30 not shown and whose face will serve as a stop.
Sur les figures suivantes (7b à 7g) les différentes phases de réalisation sont schématisées. In the following figures (7b to 7g) the various phases of realization are schematized.
La figure 7b représente la phase 1 qui correspond à l'introduction des échelles principales {1} dans la zone de stockage 23.  Figure 7b shows phase 1 which corresponds to the introduction of the main scales {1} in the storage zone 23.
Pendant cette phase les échelles secondaires (les plus courtes) {1'}, sont disposées sur les courroies 29a soit manuellement soit automatiquement à partir d'un magasin vertical qui distribue les échelles { } une par une à chaque avancée des courroies 29a. Ces dispositifs étant connus des hommes de l'art, il n'est pas utile de les rappeler ici. Les échelles { } sont amenées en position finale lorsque la première échelle { } atteint la butée de fin de course 34. Il est à noter que, comme schématisé sur la figure 7c et détail, les dites échelles { } ont été préalablement équipées de centreurs 33 rapportés ou réalisés par cintrage des HA filants 2a,2b & 2c de façon à former une pyramide.  During this phase, the secondary (shortest) scales {1 '} are arranged on the belts 29a either manually or automatically from a vertical magazine which distributes the ladders {} one by one each time the belts 29a advance. These devices being known to those skilled in the art, it is not useful to recall them here. The scales {} are brought to the final position when the first scale {} reaches the limit stop 34. It should be noted that, as shown schematically in FIG. 7c and detail, the said scales {} have previously been equipped with centering devices 33 reported or made by bending the HA hairs 2a, 2b & 2c so as to form a pyramid.
La figure 7c schématise la phase 2 qui correspond à l'introduction des échelles { } dans les échelles principales {1}. L'introduction des dites échelles {1'} dans les espaces des échelles principales {1} peut être par exemple exécutée par avance soit manuelle soit automatique du poussoir 35. Le réglage des butées 34 & 31 se fera de façon à ce que l'axe médian des échelles secondaires {1'} soit sensiblement coïncident avec le sommet de la frette 3 de l'échelle principale {1} (cf détail 7c). Figure 7c schematizes phase 2 which corresponds to the introduction of scales {} in the main scales {1}. The introduction of said scales {1 '} in the spaces of the main scales {1} can be for example performed in advance either manually or automatically from the pusher 35. The adjustment of the stops 34 & 31 will be done in such a way that the median axis of the secondary scales {1 '} is substantially coincident with the top of the fret 3 of the main scale {1} (cf detail 7c).
la figure 7d schématise la phase 3 qui correspond à la fixation des barres 2a & 2b des échelles principales {1} avec les barres 2a' & 2b' des échelles secondaires {1'}. Comme représentée sur la figure 7d, cette fixation peut être par soudure par points, ligature, collage ou de tout autre nature. FIG. 7d schematizes phase 3 which corresponds to the fixing of the bars 2a & 2b of the main scales {1} with the bars 2a '&2b' of the scales secondary {1 '}. As shown in FIG. 7d, this attachment can be by spot welding, ligation, gluing or of any other nature.
La figure 7 e représente la phase 3 qui correspond à la phase indicative de début de soudage des échelles secondaires { }. Dans cette phase, comme représenté sur le détail, les électrodes 30 & 30' sont en positions relevées. La figure 7f représente la phase 4 qui correspond à la phase indicative de fixation. Dans cette représentation comme dessinée sur le détail, les électrodes 30 & 30' sont en position travail. La manœuvre des dites électrodes peut être classiquement par vérins, mécanique (excentriques équipés d'un système élastique), ou par tout autre dispositif qui permette de maintenir sous pression les parties à fixer 2a & 2b avec 2'a & 2'b et dans le cas de fixation par soudure de commander le circuit électrique. Figure 7 e represents phase 3 which corresponds to the indicative phase of welding start of secondary scales {}. In this phase, as shown in detail, the electrodes 30 & 30 'are in raised positions. Figure 7f shows phase 4 which corresponds to the indicative fixation phase. In this representation as drawn on the detail, the electrodes 30 & 30 'are in working position. Maneuvering said electrodes can be classically by cylinders, mechanical (eccentric equipped with an elastic system), or by any other device that allows to maintain under pressure the parts to fix 2a & 2b with 2'a & 2'b and in the case of welding fixing to control the electric circuit.
La figure 7g schématise la phase 5 de fin de cycle. Dans l'intervalle de temps qui sépare les figures 7f et 7d, les courroies 29 avancent pas à pas en entraînant l'échelle principale suivant immédiatement celle qui vient d'être fixée. Les phases 7 d à 7 f se réalisent jusqu'à ce que le produit final atteigne la butée réglable 36 non représentée de fin de produit. La dite butée pouvant être soit magnétique, mécanique ou tout autre dispositif connu.  Figure 7g shows the end-of-cycle phase. In the time interval between Figures 7f and 7d, the belts 29 advance step by step leading the main scale next immediately that which has just been fixed. The phases 7 d to 7 f are realized until the final product reaches the adjustable stop 36 not shown end of product. The abutment can be either magnetic, mechanical or any other known device.
