Description

L'invention a trait à un procédé de fabrication d'une tôle à nervures ouvertes destinée à servir de coffrage et à former une armature pour un plancher collaborant.The invention relates to a method of manufacturing an open-ribbed sheet to serve as formwork and to form a frame for a collaborating floor.

Un plancher collaborant est un plancher qui combine deux matériaux, à savoir du béton et de l'acier. Dans un tel plancher, le béton assure une résistance à la pression tandis que l'acier permet une résistance à la traction.A collaborative floor is a floor that combines two materials, namely concrete and steel. In such a floor, concrete provides resistance to pressure while steel allows tensile strength.

De plus, l'absence de coffrage autre que la tôle à nervures ouvertes, permet une mise en oeuvre plus rapide en utilisant moins de béton que pour une dalle pleine en béton.In addition, the absence of formwork other than the open-ribbed sheet, allows a faster implementation using less concrete than for a solid concrete slab.

L'acier utilisé dans un plancher collaborant se présente généralement sous forme de tôle à nervures ouvertes, empilables pour faciliter leur transport. La couverture de la surface à recouvrir est assurée avec un chevauchement partiel des tôles. Ces tôles en chevauchement définissent une armature pour le plancher collaborant.The steel used in a collaborative floor is generally in the form of sheet with open ribs, stackable for easy transport. The coverage of the surface to be covered is ensured with a partial overlap of the sheets. These overlapping sheets define a reinforcement for the collaborating floor.

La liaison entre le béton et l'acier est assurée par les nervures des tôles. Il s'agit d'une liaison par frottement.The connection between concrete and steel is provided by the ribs of the sheets. This is a friction bond.

Des reliefs ménagés sur les flancs des nervures évitent un glissement du béton sur la tôle selon une direction parallèle à un axe longitudinal des nervures.Reliefs formed on the flanks of the ribs prevent slippage of the concrete on the sheet in a direction parallel to a longitudinal axis of the ribs.

GB-A-2 306 526 , sur lequel est basé le préambule de la revendication 1 annexée, décrit une tôle pour plancher collaborant comprenant des nervures trapézoïdales dont les sommets et les bases sont pourvus de reliefs parallèles à un axe longitudinal de la nervure. Dans un mode de réalisation, les flancs des nervures sont pourvus de reliefs de forme complexe. GB-A-2,306,526 , on which the preamble of appended claim 1 is based, describes a collaborating floor plate comprising trapezoidal ribs whose vertices and bases are provided with reliefs parallel to a longitudinal axis of the rib. In one embodiment, the flanks of the ribs are provided with reliefs of complex shape.

Si elles optimisent la liaison entre le béton et l'acier, de telles tôles équipées de reliefs sur les flancs des nervures présentent comme inconvénient, lors de leur mise en place, de ne pas se recouvrir parfaitement au niveau de la zone de chevauchement. La présence des reliefs dans la zone de recouvrement induit un espace dans lequel du laitier peut passer lors du coulage du béton sur les tôles.If they optimize the connection between the concrete and the steel, such plates equipped with reliefs on the flanks of the ribs have the disadvantage, when they are put in place, of not overlapping perfectly at the level of the overlap zone. The presence of reliefs in the overlap zone induces a space in which slag can pass during the pouring of concrete on the sheets.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant de fabriquer une tôle à nervures ouvertes pour plancher collaborant, présentant un recouvrement optimal, tout en garantissant la liaison entre le béton et l'acier.It is these drawbacks that the invention intends to remedy more particularly by proposing to manufacture a sheet with open ribs for collaborating flooring, presenting an optimal covering, while guaranteeing the connection between the concrete and the steel.

A cet effet, l'invention a pour objet un procédé de fabrication d'une tôle à nervures ouvertes, tel que défini à la revendication 1.For this purpose, the subject of the invention is a method of manufacturing an open-ribbed sheet, as defined in claim 1.

En réalisant des zones de recouvrement où les reliefs sont, au moins partiellement, absents, on minimise le jour entre les deux tôles lorsqu'elles se recouvrent et donc on limite les risques de coulure du laitier entre ces dernières, cela tout en préservant une liaison optimale, d'une part, entre les tôles et, d'autre part, entre la tôle et le béton.By producing overlapping areas where the reliefs are at least partially absent, the day between the two sheets is minimized when they overlap and therefore the risks of slag flow between them are limited, while preserving an optimal connection, on the one hand, between the sheets and, on the other hand, between the sheet and the concrete.

Des aspects avantageux mais non obligatoires de l'invention sont spécifiés aux revendications dépendantes.Advantageous but non-mandatory aspects of the invention are specified in the dependent claims.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés dans lesquels :

  • la figure 1 est une vue de côté d'un plancher collaborant fini réalisé avec une tôle fabriquée conformément à l'invention,
  • la figure 2 est une vue générale en perspective, à la même échelle que la figure 1, de la tôle de la figure 1, représentée seule,
  • la figure 3 est une vue générale, à plus petite échelle et sous un autre angle, de deux tôles similaires à celle illustrée aux figures 1 et 2, en configuration de pré-montage,
  • la figure 4 est une vue, à plus grande échelle, du détail IV à la figure 3,
  • la figure 5 est une vue de côté selon la flèche V et à la même échelle que la figure 3,
  • la figure 6 est une vue analogue à la figure 3, à la même échelle que celle ci, les tôles étant représentées en position montée, c'est-à-dire se recouvrant partiellement et
  • la figure 7 est une vue à plus grande échelle du détail \/II à la figure 6.
The invention will be better understood and other advantages thereof will appear more clearly on reading the description which follows, given solely by way of example and with reference to the appended drawings in which:
  • the figure 1 is a side view of a finished collaborating floor made with a sheet made according to the invention,
  • the figure 2 is a general perspective view, on the same scale as the figure 1 , sheet metal figure 1 , represented alone,
  • the figure 3 is a general view, on a smaller scale and from another angle, of two sheets similar to the one illustrated in Figures 1 and 2 , in pre-assembly configuration,
  • the figure 4 is a view, on a larger scale, from detail IV to figure 3 ,
  • the figure 5 is a side view along arrow V and at the same scale as the figure 3 ,
  • the figure 6 is a view similar to the figure 3 , on the same scale as this one, the sheets being represented in mounted position, that is to say partially overlapping and
  • the figure 7 is a larger-scale view of detail \ / II to the figure 6 .

Le plancher collaborant 1 représenté à la figure 1 comprend une tôle à nervures ouvertes 2 formant une armature propre à recevoir du béton 3.The collaborating floor 1 represented in the figure 1 comprises a sheet with open ribs 2 forming a frame suitable for receiving concrete 3.

Dans le béton 3, on insère à une distance donnée au dessus de la tôle 2, en regardant la figure 1, des fers à béton 4. Ces fers à béton 4, avantageusement disposés en treillis, améliorent la résistance du plancher 1. Le béton 3 est coulé sur la tôle 2 de sorte qu'il recouvre celle-ci et entoure les fers à béton 4 sur une épaisseur minimale d'un cm autour des fers à béton.In the concrete 3, insert at a given distance above the sheet 2, looking at the figure 1 4. These concrete bars 4, advantageously arranged in lattice, improve the strength of the floor 1. The concrete 3 is cast on the sheet 2 so that it covers the latter and surrounds the reinforcing bars 4 on a minimum thickness of one cm around the reinforcing bars.

En regardant la figure 1, la tôle 2 forme la face inférieure 100 du plancher 1. La face libre supérieure 101 de celui-ci est formée par le béton 3, une fois ce dernier sec et lissé.Looking at the figure 1 , the sheet 2 forms the lower face 100 of the floor 1. The upper free face 101 thereof is formed by the concrete 3, once the latter dry and smoothed.

La tôle 2 comprend plusieurs nervures ouvertes 5. Ces nervures 5 sont régulièrement disposées parallèlement à la plus petite dimension ℓ de la tôle 2. En variante, elles peuvent être disposées parallèlement à la plus grande dimension L de la tôle 2.The sheet 2 comprises several open ribs 5. These ribs 5 are regularly arranged parallel to the smallest dimension ℓ of the sheet 2. In a variant, they may be arranged parallel to the largest dimension L of the sheet 2.

Il est à noter que, généralement, les tôles sont rectangulaires. Dans un mode de réalisation non illustré, elles sont carrées.It should be noted that, generally, the sheets are rectangular. In a non-illustrated embodiment, they are square.

Comme cela est plus particulièrement visible à la figure 1, chaque nervure 5 a, en section transversale, une forme trapézoïdale. La base 6 de chaque nervure 5 est ouverte et comprend une partie sans matière, définie par un plan géométrique repéré par une ligne C en pointillés aux figures 2 et 3. Les bases 6 de toutes les nervures 5 d'une même tôle 2 sont orientées vers le bas, en regardant la figure 1. En d'autres termes, les bases 6 des nervures 5 participent, une fois le plancher réalisé, à définir la face inférieure 100 de celui-ci, à savoir la face métallique du plancher 1.As this is particularly visible in the figure 1 each rib 5 has, in cross section, a trapezoidal shape. The base 6 of each rib 5 is open and comprises a part without material, defined by a geometric plane marked by a dotted line C figures 2 and 3 . The bases 6 of all the ribs 5 of the same sheet 2 are oriented downwards, looking at the figure 1 . In other words, the bases 6 of the ribs 5 participate, once the floor is made, to define the lower face 100 thereof, namely the metal face of the floor 1.

La face supérieure 7 de chaque nervure 5, à savoir le sommet du trapèze de chaque nervure 5, est pourvue d'au moins une rainure longitudinale 8. La partie 9 plane de la tôle 2 située entre deux nervures 5 et reliant les bases 6 de ces deux nervures 5 voisines, est également équipée d'au moins une rainure longitudinale 10. Les rainures 8 et 10 sont disposées parallèlement. Elles sont orientées selon une direction parallèle à un axe longitudinal A de chaque nervure 5. En d'autres termes, les rainures 8 et 10 sont également orientées parallèlement à la petite dimension ℓ de la tôle 2.The upper face 7 of each rib 5, namely the vertex of the trapezium of each rib 5, is provided with at least one longitudinal groove 8. The flat portion 9 of the sheet 2 located between two ribs 5 and connecting the bases 6 of these two adjacent ribs 5 is also equipped with at least one longitudinal groove 10. The grooves 8 and 10 are arranged in parallel. They are oriented in a direction parallel to a longitudinal axis A of each rib 5. In other words, the grooves 8 and 10 are also oriented parallel to the small dimension ℓ of the sheet 2.

Ces rainures 8, 10 sont ménagées sur, respectivement, toutes les nervures 5 et toutes les parties planes 9 de la tôle 2. En variante, elles n'équipent que certaines des nervures 5 et/ou certaines des parties planes 9. Dans un mode de réalisation non illustré, la face 7 et les parties 9 de chaque nervure 5 sont dépourvues de rainures.These grooves 8, 10 are formed on, respectively, all the ribs 5 and all the plane portions 9 of the sheet 2. In a variant, they equip only some of the ribs 5 and / or some of the plane portions 9. embodiment not shown, the face 7 and the parts 9 of each rib 5 are devoid of grooves.

Les largeurs des rainures 8 et 10 sont différentes. En variante elles peuvent être identiques.The widths of the grooves 8 and 10 are different. Alternatively they may be identical.

Les rainures 8 et 10 forment des guides et des logements de réception pour des éléments de fixation des tôles 2. La fixation des tôles 2 l'une sur l'autre est réalisée par des organes connus en soi, par exemple des vis, des rivets ou des boulons.The grooves 8 and 10 form guides and receiving housings for fastening elements of the plates 2. The fastening of the sheets 2 to one another is carried out by members known per se, for example screws, rivets or bolts.

Les flancs 11 et 12 de chaque nervure 5, c'est-à-dire les parois reliant sa base 6 à son sommet 7, sont dans l'exemple légèrement inclinées par rapport à un axe vertical B. Cet axe B est perpendiculaire à un plan principal P de la tôle 2 dans lequel se situent les parties planes 9. L'angle d'inclinaison a entre, d'une part, un flanc 11 ou 12 et, d'autre part, l'axe B peut être compris entre 10° et 170°.The flanks 11 and 12 of each rib 5, that is to say the walls connecting its base 6 to its top 7, are in the example slightly inclined relative to a vertical axis B. This axis B is perpendicular to a main plane P of the sheet 2 in which the planar portions are situated 9. The inclination angle α between, on the one hand, a sidewall 11 or 12 and, on the other hand, the axis B can be between 10 ° and 170 °.

Les flancs 11, 12 de chaque nervure 5 sont pourvus de reliefs 13. En l'espèce, ces reliefs sont en forme de parallélogramme rectangle. En variante non illustrée, ils peuvent avoir d'autres formes, par exemple trapézoïdale, carrée ou circulaire. Ils sont régulièrement espacés et de dimensions telles qu'ils occupent la majeure partie de la largeur L11-L12 des flancs 11 et 12. Dans un mode de réalisation non illustré, la répartition des reliefs 13 est différente. Avantageusement, la répartition des reliefs 13 sur les flancs 11 et 12 est identique sur toutes les nervures 5. En variante non illustrée, elle est différente d'une nervure à l'autre.The flanks 11, 12 of each rib 5 are provided with reliefs 13. In this case, these reliefs are in the form of a rectangular parallelogram. In variant not illustrated, they may have other shapes, for example trapezoidal, square or circular. They are regularly spaced and of such dimensions that they occupy most of the width L11-L12 of the flanks 11 and 12. In a non-illustrated embodiment, the distribution of the reliefs 13 is different. Advantageously, the distribution of the reliefs 13 on the sides 11 and 12 is identical on all the ribs 5. As a variant not shown, it is different from one rib to another.

Ces reliefs 13 s'étendent vers l'extérieur, à partir du flanc 11 ou 12 d'une nervure 5 sur lequel ils sont ménagés, en direction du flanc 12 ou 11 d'une nervure 5 voisine. Les reliefs 13 sont répartis, en l'espèce de manière régulière, sur toute la longueur de chaque nervure 5, c'est-à-dire sur toute la petite dimension ℓ de la tôle 2.These reliefs 13 extend outwardly from the sidewall 11 or 12 of a rib 5 on which they are formed, towards the sidewall 12 or 11 of a neighboring rib 5. The reliefs 13 are distributed, in this case regularly, over the entire length of each rib 5, that is to say over the entire small dimension ℓ of the sheet 2.

Comme illustré aux figures 2 et 3, certains reliefs 13 sont situés dans une zone Z destinée au recouvrement entre deux tôles 2 lorsque ces dernières sont en position pour former un plancher collaborant. Ici, le terme recouvrement désigne le recouvrement, sur au moins une partie, d'au moins une nervure 5 d'une tôle 2 par une nervure 5 d'une autre tôle 2 et non pas le seul recouvrement des parties planes 9 de deux tôles 2. Cette zone Z est d'une largeur comprise entre 5 et 50 mm et avantageusement voisine de 25 mm. Elle s'étend sur toute la grande dimension L des tôles 2, au voisinage des bords des tôles 2 se chevauchant. Dans cette zone Z, les reliefs 13 de la tôle recouverte présentent une partie orientée vers la tôle recouvrante dépourvue de reliefs, en l'espèce une partie aplanie 14, 15 ou 16.As illustrated in figures 2 and 3 some reliefs 13 are located in a zone Z for overlapping between two sheets 2 when the latter are in position to form a collaborating floor. Here, the term "covering" designates the covering, on at least one part, of at least one rib 5 of a sheet 2 by a rib 5 of another sheet 2 and not the only covering of the flat portions 9 of two sheets 2. This Z zone has a width of between 5 and 50 mm and advantageously close to 25 mm. It extends over the entire large dimension L of the sheets 2, in the vicinity of the overlapping edges of the sheets 2. In this zone Z, the reliefs 13 of the covered sheet have a portion oriented towards the covering sheet devoid of reliefs, in this case a flattened portion 14, 15 or 16.

Comme illustré à la figure 2, les dimensions de la partie aplanie 14, 15 ou 16 de chaque relief 13 dans la zone Z varient selon les dimensions de la portion des reliefs 13 qui empiète sur la zone Z. A titre d'exemple, la figure 2 illustre une tôle où seulement trois reliefs 13, visibles sur les faces 11 des nervures 5 de la tôle 2, empiètent sur la zone Z. Les parties aplanies 14, 15, 16 de ces reliefs sont de plus en plus importantes, de la partie 14 à la partie 16, par rapport à une dimension principale de chaque relief 13.As illustrated in figure 2 , the dimensions of the flattened portion 14, 15 or 16 of each relief 13 in the zone Z vary according to the dimensions of the portion of the reliefs 13 which encroaches on the zone Z. For example, the figure 2 illustrates a sheet where only three reliefs 13, visible on the faces 11 of the ribs 5 of the sheet 2, encroach on the zone Z. The flattened portions 14, 15, 16 of these reliefs are increasingly important, the part 14 in part 16, with respect to a principal dimension of each relief 13.

Le flanc 12 de chaque nervure 5, visible aux figures 3 à 5, comprend également des reliefs présentant des parties aplanies dans la zone Z. Comme cela est plus particulièrement visible aux figures 6 et 7, lorsque l'on positionne deux tôles 2 pour qu'elles se recouvrent partiellement sur une distance correspondant à la largeur prédéterminée de la zone Z, selon une direction parallèle à leur petite dimension ℓ, le bord libre 200 de la tôle 2 supérieure repose sur un bord libre 201 de la tôle 2 inférieure, cela avec un jeu J minimal entre les deux tôles 2 puisque la partie aplanie des reliefs 13 ne gêne pas cette liaison. En d'autres termes, au niveau de la zone de recouvrement Z, il n'y a pas de partie en saillie d'un relief 13 susceptible de maintenir un jeu J important les deux tôles 2 se chevauchant, ce qui risquerait, outre le fait de créer une liaison affaiblie entre les tôles 2, de faciliter le passage du laitier entre les tôles 2.The flank 12 of each rib 5, visible at Figures 3 to 5 , also includes reliefs having flattened portions in zone Z. As is more particularly visible at figures 6 and 7 when positioning two sheets 2 so that they partially overlap for a distance corresponding to the predetermined width of the zone Z, in a direction parallel to their small dimension ℓ, the free edge 200 of the upper sheet 2 rests on a free edge 201 of the lower plate 2, this with a minimum clearance J between the two plates 2 since the flattened portion of the reliefs 13 does not interfere with this connection. In other words, at the level of the overlap area Z, there is no projecting portion of a relief 13 capable of maintaining a clearance J important the two overlapping sheets 2, which could, in addition to the to create a weakened connection between the sheets 2, to facilitate the passage of the slag between the sheets 2.

Une telle liaison entre les tôles 2, à jeu J minimal, à savoir voisin de 1 mm, permet également lors des opérations de fixation mutuelle des tôles 2 entre elles, couramment dénommées « couturage », d'insérer de manière efficace des organes de fixation, tels que des vis, des pointes, des boulons ou des rivets dans les rainures 8 et/ou 10. En variante, la fixation mutuelle des tôles 2 est réalisée par d'autres techniques connues en soi, par exemple par soudage ou collage.Such a connection between the plates 2, with minimal clearance J, ie close to 1 mm, also makes it possible in the operations of mutual attachment of the sheets 2 between them, commonly called "seaming", to effectively insert fasteners , such as screws, points, bolts or rivets in the grooves 8 and / or 10. Alternatively, the mutual attachment of the sheets 2 is achieved by other techniques known per se, for example by welding or gluing.

Le nombre de reliefs 13 susceptibles d'empiéter, au moins partiellement, dans la zone Z varie d'une tôle 2 à l'autre compte tenu du procédé de fabrication de ces dernières. Ce procédé est maintenant décrit. Dans un mode de réalisation non représenté, les parties planes 9 et/ou les sommets 7 des nervures 5 sont également pourvus de relief 13.The number of reliefs 13 likely to encroach, at least partially, in the zone Z varies from one sheet 2 to the other, given the manufacturing process of the latter. This process is now described. In an embodiment not shown, the planar portions 9 and / or the vertices 7 of the ribs 5 are also provided with relief 13.

On réalise les tôles 2 à nervures ouvertes destinées à former une armature pour un plancher collaborant à partir de bandes métalliques enroulées pour former des bobines, non illustrées et connues en soi.Plates 2 with open ribs are made to form a reinforcement for a collaborating floor from wound metal strips to form coils, not illustrated and known per se.

La première opération consiste à former par emboutissage, à l'aide d'un outil de type poinçon et connu en soi, des reliefs 13 dans la bande lorsque celle-ci est déroulée. Cette première étape permet également, par la présence des reliefs 13, de définir la position des nervures 5 et des rainures 8, 10 sur la bande, pour une réalisation dans une étape ultérieure. En d'autres termes, les reliefs 13, alignés sur la bande forment des lignes discontinues de guidage.The first operation is to form by stamping, using a punch-type tool and known per se, reliefs 13 in the strip when it is unwound. This first step also allows, by the presence of the reliefs 13, to define the position of the ribs 5 and grooves 8, 10 on the strip, for an embodiment in a subsequent step. In other words, the reliefs 13, aligned on the strip form discontinuous guide lines.

Dans deux étapes suivantes, par profilage ou, éventuellement, par emboutissage et à l'aide d'un outil de forme adaptée et différente de la forme de celui utilisé lors de la première étape, on réalise d'abord les rainures 8, 10 et ensuite les nervures 5.In two following steps, by profiling or, optionally, by stamping and with the aid of a tool of suitable shape and different from the shape of the one used in the first step, the grooves 8, 10 and then the ribs 5.

Le profilage des rainures 8, 10 et des nervures 5 est réalisé avantageusement en plusieurs passes successives jusqu'à obtenir les dimensions voulues des rainures 8, 10 et des nervures 5. Dans un mode de réalisation non représenté, la réalisation des rainures 8, 10 et des nervures 5 est obtenue en une seule passe à l'aide d'un outil de forme complexe.The profiling of the grooves 8, 10 and ribs 5 is advantageously made in several successive passes until the desired dimensions of the grooves 8, 10 and ribs 5 are obtained. In one embodiment, not shown, the grooves 8, 10 are formed. and ribs 5 is obtained in a single pass using a tool of complex shape.

Lorsque la bande est profilée et/ou emboutie et présente l'ensemble des nervures 5, des rainures 8, 10 et des reliefs 13 que l'on retrouve sur une tôle 2 finie, on coupe régulièrement cette bande afin d'individualiser chaque tôle 2.When the strip is profiled and / or stamped and has all the ribs 5, grooves 8, 10 and reliefs 13 found on a finished sheet 2, this strip is regularly cut to individualize each sheet 2 .

La coupure de la bande s'effectue de manière à ce qu'elle définisse, ici, la petite dimension ℓ de la tôle 2. En variante non illustrée, la coupure est réalisée de manière à définir la plus grande dimension de la tôle finie 2. On utilise pour couper cette bande métallique un outil connu en soi de type cisaille, non illustré, comprenant au moins une mâchoire d'appui et une mâchoire mobile.The cutting of the strip is carried out so that it defines, here, the small dimension ℓ of the sheet 2. As a variant not shown, the cut is made so as to define the largest dimension of the finished sheet 2 We use to cut this band metallic tool known per se shear type, not shown, comprising at least one support jaw and a movable jaw.

Lors de la coupe de chaque tôle 2 dans la bande, on dispose, au niveau de la mâchoire mobile de la cisaille, un contre-outil dont les dimensions correspondent à celles de la zone Z. Avantageusement, il s'agit d'un poinçon à face plane, connu en soi. La face plane du poinçon a une largeur correspondant à celle de la zone Z. Ainsi, lors de la séparation d'une tôle de la bande, on écrase ou « aplanit » simultanément tous les reliefs 13 situés à proximité de la ligne de coupe et s'étendant dans une région dont la largeur correspond à la longueur de la zone Z. L'aplanissement des reliefs 13 par cet outil est effectué sur le bord libre de la bande destinée à former un bord 200 ou 201 d'une autre tôle 2. Ainsi, on réalise l'aplanissement des reliefs 13 avant la séparation de la tôle 2 de la bande. En variante, l'aplanissement des reliefs 13 est effectué après la séparation, étant entendu que cela nécessite une reprise des tôles 2 individualisées.When cutting each sheet 2 in the strip, there is, at the mobile jaw of the shears, a counter-tool whose dimensions correspond to those of the zone Z. Advantageously, it is a punch flat-faced, known in itself. The flat face of the punch has a width corresponding to that of the zone Z. Thus, during the separation of a sheet of the strip, all the reliefs 13 located near the cutting line are simultaneously crushed or "flattened". extending in a region whose width corresponds to the length of the zone Z. The flattening of the reliefs 13 by this tool is performed on the free edge of the strip intended to form an edge 200 or 201 of another sheet 2 Thus, the planarization of the reliefs 13 is carried out before the separation of the sheet 2 of the strip. As a variant, the planarization of the reliefs 13 is carried out after the separation, it being understood that this requires a recovery of the individualized sheets 2.

Un tel procédé est simple à mettre en oeuvre et ne nécessite qu'un contre-outil, pour l'aplanissement des reliefs 13, fixé sur l'outil de coupe de la bande. En d'autres termes, il est aisé de fabriquer de telles tôles 2 en utilisant des installations connues de fabrication de tôles 2, après adaptation de celles-ci pour incorporer un poinçon à face plane ou un organe d'aplanissement équivalent.Such a method is simple to implement and requires only a counter-tool for flattening the reliefs 13, fixed on the cutting tool of the strip. In other words, it is easy to manufacture such sheets 2 using known sheet metal manufacturing facilities 2, after adaptation thereof to incorporate a flat-faced punch or equivalent planarizing member.

Un tel procédé permet de réaliser, sur chaque tôle, un détrompeur indiquant que chaque tôle 2 a un côté destiné à recouvrir une tôle 2 et un autre côté pouvant être recouvert pour une tôle 2.Such a method makes it possible to produce, on each sheet, a polarizer indicating that each sheet 2 has a side intended to cover a sheet 2 and another side that can be covered for a sheet 2.

En fonction de la zone que l'on veut recouvrir, on modifie le contre-outil pour un outil plus ou moins large, afin d'écraser les reliefs 13 sur une position plus ou moins importante.Depending on the area to be covered, it modifies the counter-tool for a tool more or less wide, to crush the reliefs 13 to a more or less important position.

Claims (12)

  1. Process for the production of a metal sheet (2) with open ribs intended to be used for shuttering and to form a reinforcement for a floor with cast-in-place topping (1), comprising successive steps consisting of:

    c) cutting the band in order to customise the metal sheet (2),
    characterised in that the process comprises at least one step of:
    d) for the or each raised area (13) that is at least partially located in a zone (Z) of the metal sheet (2) intended to be covered by another metal sheet to form a floor with cast-in-place topping (1), smoothing off the raised area over a distance corresponding to the part (14; 15; 16) of the raised area located in said zone of the metal sheet.
  2. Process according to claim 1, characterised in that step d) is performed during step c) after the metal sheet (2) is separated from the band.
  3. Process according to claim 1, characterised in that step d) is performed during step c) before the metal sheet (2) is separated from the band.
  4. Process according to claim 3, characterised in that the or each raised area (13) that is smoothed off during step d) is located close to a cutting line of the metal sheet (2) formed in step c).
  5. Process according to claim 4, characterised in that to smooth off the or each raised area (13) during step d), a die is used that is fixed to a tool for cutting the band used to conduct step c).
  6. Process according to claim 5, characterised in that the die is a punching die with a plane face, the width of which corresponds to that of said zone (Z) of the metal sheet (2).
  7. Process according to any one of claims 1 to 3, characterised in that the or each raised area (13) that is smoothed off during step d) is located on a free edge of the band.
  8. Process according to any one of the preceding claims, characterised in that during step a) a sufficient number of raised areas (13) are formed to be distributed, in step b), over the entire length of the two opposing flanks (11, 12) of one, or even each of the ribs (5).
  9. Process according to one of the preceding claims, characterised in that the raised areas (13) formed in step a) are parallelepipedal in form.
  10. Process according to any one of the preceding claims, characterised in that said zone (Z) of the metal sheet (2) has a width ranging between 5 and 50 mm.
  11. Process according to claim 10, characterised in that said zone (Z) of the metal sheet (2) has a width close to 25 mm.
