Description

Domaine technique:Technical area:

La présente invention concerne un moule pour la fabrication d'éléments profilés pourvus d'armatures dépassantes, notamment de poutrelles dites à couture.The present invention relates to a mold for the manufacture of profiled elements provided with protruding reinforcements, in particular so-called sewing beams.

Technique antérieure :Prior art:

Dans le domaine du bâtiment, il est connu de fabriquer en usine ce type d'éléments profilés, tels que des poutres ou des poutrelles, munis sur toute ou une partie de leur longueur d'armatures dépassantes permettant d'assurer leur liaison mécanique avec le matériau coulé sur chantier tel que le béton, notamment pour répondre aux réglementations sismiques en vigueur. Ces éléments profilés sont des produits moulés à base de béton notamment et peuvent être précontraints ou non. Ils comportent des armatures dépassantes formées de tiges ou de fils d'acier dits de couture en forme de U ou de sinusoïde, la boucle du U ou les boucles d'un même côté de la sinusoïde dépassant du sommet des éléments profilés.In the field of building, it is known to manufacture in the factory this type of profiled elements, such as beams or beams, provided over all or part of their length of protruding reinforcements to ensure their mechanical connection with the material poured on site such as concrete, in particular to meet seismic regulations in force. These profiled elements are molded products based on concrete in particular and can be prestressed or not. They comprise protruding reinforcements formed of U-shaped or sinusoidal stems or steel wires, the loop of the U or the loops on the same side of the sinusoid protruding from the top of the profiled elements.

Ces éléments profilés sont traditionnellement fabriqués dans des moules dont le fond est constitué d'une pièce en caoutchouc, pourvue d'une fente filante dans laquelle est introduite l'armature dépassante, comme dans les publications FR-A-2.375.016 et FR-A-2.228.145 . Cette technique présente plusieurs inconvénients et la qualité des éléments profilés est très aléatoire. En effet, la profondeur du moule est variable au fur et à mesure des cycles de moulage due aux résidus de béton qui y restent collés. La hauteur des éléments profilés n'est donc pas garantie. Par conséquent, ces fonds de moule doivent être périodiquement retirés pour être nettoyés, ce qui représente une opération très contraignante et coûteuse. De plus, ces fonds de moule doivent être remplacés régulièrement en raison de leur vieillissement prématuré du aux huiles de coffrage et aux cycles de chauffe, ce qui représente également une opération fastidieuse et très coûteuse compte tenu du coût d'investissement de ces pièces.These profiled elements are traditionally manufactured in molds whose bottom consists of a rubber part, provided with a slot in which is introduced the projecting frame, as in the publications FR-A-2375016 and FR-A-2228145 . This technique has several disadvantages and the quality of the profiled elements is very random. Indeed, the depth of the mold is variable as molding cycles due to the remaining concrete residues. The height of the profiled elements is not guaranteed. Therefore, these mold bottoms must be periodically removed for cleaning, which is a very burdensome and expensive operation. In addition, these mold bottoms must be replaced regularly due to premature aging of the formwork oils and heating cycles, which is also a tedious and very expensive operation considering the investment cost of these parts.

Les publications EP-A-0.260.189 et FR-A-2.200.777 proposent de réaliser ces éléments profilés dans un moule ouvrant dont les parois latérales comportent un joint d'étanchéité de fermeture apte à s'écraser lorsque ces parois sont rapprochées l'une de l'autre pour fermer le fond du moule de manière étanche autour de l'armature dépassante. Cette technique nécessite, par conséquent, des mécanismes d'actionnement des parois latérales mobiles complexes, encombrants et très coûteux, sachant que la longueur des moules peut atteindre 80 à 100 m. De plus, les joints d'étanchéité de fermeture s'usent rapidement sous l'effet des huiles de coffrage et des cycles de chauffage. L'étanchéité n'est donc pas garantie et nécessite un remplacement périodique de ces joints, d'où une opération longue et coûteuse.The publications EP-A-0260189 and FR-A-2200777 propose to produce these profiled elements in an opening mold whose side walls comprise a sealing seal capable of crashing when these walls are close to one another to close the bottom of the mold in a sealed manner around the protruding frame. This technique therefore requires mechanisms for actuating the complex, bulky and very expensive mobile side walls, knowing that the length of the molds can reach 80 to 100 m. In addition, the closing seals wear out quickly due to formwork oils and heating cycles. The seal is not guaranteed and requires periodic replacement of these joints, resulting in a long and expensive operation.

Exposé de l'invention :Presentation of the invention

La présente invention vise à pallier ces inconvénients en proposant un moule de conception simple, peu encombrant et facile d'entretien, permettant la fabrication d'éléments profilés calibrés de qualité, la reproductibilité de cette qualité, ainsi que le positionnement précis des armatures de couture. Le but de l'invention est également d'atteindre des prix de revient économiquement rentables, de faibles coûts de maintenance et de réduire les consommables. Un autre but de l'invention est que l'opération de moulage soit mécanisable, voire automatisable pour s'insérer dans un procédé industriel.The present invention aims to overcome these disadvantages by providing a mold of simple design, compact and easy to maintain, allowing the manufacture of quality calibrated profile elements, the reproducibility of this quality, as well as the precise positioning of the sewing frames. . The object of the invention is also to achieve cost-effective manufacturing costs, low maintenance costs and reduce consumables. Another object of the invention is that the molding operation is mechanizable, or even automated to fit into an industrial process.

Dans ce but, l'invention concerne un moule du genre indiqué en préambule, caractérisé en ce qu'il comporte au moins un coffrage de section complémentaire et inverse à celle de l'élément profilé à fabriquer, ce coffrage comportant deux parois latérales fixes et un fond pourvu d'au moins une ouverture s'étendant sur au moins une partie dudit coffrage et destinée à recevoir au moins une partie de l'armature dépassante et en ce qu'il comporte des moyens d'obturation de ladite ouverture disposés à l'extérieur dudit coffrage et agencés pour obturer les espaces résiduels entre les parois de l'ouverture et les parois de l'armature dépassante.For this purpose, the invention relates to a mold of the type indicated in the preamble, characterized in that it comprises at least one formwork of complementary section and inverse to that of the profiled element to be manufactured, this formwork comprising two side walls. fixed and a bottom provided with at least one opening extending over at least a portion of said formwork and intended to receive at least a portion of the projecting frame and in that it comprises means for closing said opening arranged outside said formwork and arranged to close the residual spaces between the walls of the opening and the walls of the projecting frame.

Ainsi, le moule selon l'invention étant à parois fixes supprime tout mécanisme complexe nécessaire dans les moules ouvrants. Son fond étant rigide évite les inconvénients du fond en élastomère. Les moyens d'obturation de l'ouverture étant disposés à l'extérieur du coffrage évite tout contact direct avec le béton et les huiles de coffrage.Thus, the mold according to the invention being fixed-walled eliminates any complex mechanism required in the opening molds. Its bottom being rigid avoids the disadvantages of the elastomer bottom. The shutter means of the opening being disposed outside the formwork avoids any direct contact with the concrete and the formwork oils.

L'ouverture peut être une fente filante s'étendant sensiblement sur toute la longueur du coffrage ou plusieurs fentes successives réparties sensiblement sur toute la longueur du coffrage.The opening may be a slotted slot extending substantially the entire length of the formwork or several successive slots distributed substantially over the entire length of the formwork.

Dans une première forme de réalisation, les moyens d'obturation comportent au moins un organe d'étanchéité disposé d'un côté de l'ouverture et au moins un contre-appui disposé de l'autre côté de cette ouverture.In a first embodiment, the closure means comprise at least one sealing member disposed on one side of the opening and at least one counter-support disposed on the other side of this opening.

Ces moyens d'obturation peuvent être mobiles et couplés à des moyens d'actionnement entre une position ouverte dans laquelle ils libèrent l'ouverture et une position fermée dans laquelle ils obturent cette ouverture emprisonnant l'armature dépassante, ces moyens d'actionnement comportant au moins un bras mobile couplé d'une part à l'organe d'étanchéité et d'autre part à un actionneur.These closure means may be movable and coupled to actuating means between an open position in which they release the opening and a closed position in which they seal this opening enclosing the projecting armature, these actuating means comprising at least one movable arm coupled on the one hand to the sealing member and on the other hand to an actuator.

Ces moyens d'obturation peuvent être fixes et l'organe d'étanchéité peut comporter une multitude d'éléments souples s'étendant sensiblement perpendiculairement à l'axe de l'ouverture, cet organe d'étanchéité pouvant être choisi parmi les brosses ou les lamelles.These sealing means may be fixed and the sealing member may comprise a multitude of flexible elements extending substantially perpendicular to the axis of the opening, this sealing member may be selected from brushes or lamellae.

Le contre-appui peut être formé d'au moins une paroi longitudinale s'étendant d'un bord de l'ouverture à l'extérieur du coffrage dans une direction sensiblement perpendiculaire au fond. De préférence, il comporte une butée basse sur laquelle repose l'armature dépassante lorsqu'elle est introduite dans l'ouverture.The abutment may be formed of at least one longitudinal wall extending from an edge of the opening to the outside of the formwork in a direction substantially perpendicular to the bottom. Preferably, it comprises a low abutment on which the protruding armature rests when it is introduced into the opening.

Dans une autre forme de réalisation, les moyens d'obturation comportent au moins deux organes d'étanchéité disposés en regard dans les bords opposés de l'ouverture.In another embodiment, the closure means comprise at least two sealing members disposed opposite in the opposite edges of the opening.

Dans les deux cas, l'organe d'étanchéité peut être formé d'un profilé longitudinal, d'un boudin ou d'une lèvre, en matériau élastique à base d'élastomère ou de caoutchouc. Il peut aussi être formé d'un profilé longitudinal gonflable par un produit gazeux ou liquide. Il peut encore être formé d'une tôle découpée en fonction du profil de l'armature dépassante.In both cases, the sealing member may be formed of a longitudinal section, a flange or a lip, of elastic material based on elastomer or rubber. It may also be formed of an inflatable longitudinal profile with a gaseous or liquid product. It can also be formed of a sheet cut according to the profile of the protruding frame.

De manière préférentielle, l'organe d'étanchéité est démontable pour être interchangeable.Preferably, the sealing member is removable to be interchangeable.

Le moule selon l'invention peut comporter plusieurs coffrages, disposés symétriquement deux à deux. Dans ce cas, l'actionneur peut être commun à chaque paire de coffrages.The mold according to the invention may comprise several forms, arranged symmetrically in pairs. In this case, the actuator may be common to each pair of forms.

Le moule peut également comporter au moins une butée basse au droit de chaque ouverture des coffrages sur laquelle repose l'armature dépassante lorsqu'elle est introduite dans cette ouverture.The mold may also include at least one bottom stop to the right of each opening of the formwork on which the protruding frame when it is introduced into this opening.

Ce moule est avantageusement destiné à être monté sur un banc de moulage fixe ou sur une table mobile entrant dans une unité de production du type carrousel.This mold is advantageously intended to be mounted on a fixed molding bench or on a mobile table entering a production unit of the carousel type.

En référence aux figures, le moule de fabrication 10, 20 selon l'invention est destiné au moulage en usine d'éléments profilés l, à base de béton notamment, précontraint ou non, armé ou non, tels que des poutres ou des poutrelles dites à couture, dont un exemple est représenté à la figure 1. Cet élément profilé 1 a une forme en T inversé définissant une âme verticale 2 et deux ailes latérales 3. Il comporte une armature dépassante 5 dite de couture dont la fonction est d'offrir un meilleur accrochage au béton du plancher coulé sur chantier conformément aux normes antisismiques. Cette armature dépassante 5 peut être formée de tiges d'acier verticales droites, à crochet ou selon toute autre forme. Elle peut aussi être formée de fils d'acier en forme de U ou en forme de sinusoïde comme illustré aux figures 2A à 2C. La figure 2A illustre une armature 5a sinusoïdale simple, la figure 2B illustre une armature 5b sinusoïdale simple additionnée d'une armature centrale filante 6 et la figure 2C illustre une armature 5c sinusoïdale simple dont les boucles inférieures 7 sont déviées de part et d'autre du plan de symétrie P. Dans le cas de la fabrication d'éléments profilés 1 précontraints ou armés, c'est-à-dire comportant dans leur partie médiane des câbles de précontraintes ou des armatures principales 8 (voir fig. 5), les armatures dépassantes 5a, 5b des figures 2A et 2B sont décalées par rapport au plan de symétrie P de l'élément profilé 1 pour ne pas interférer avec ces câbles de précontrainte ou armatures principales 8. L'armature dépassante 5c de la figure 2C est conçue pour pouvoir être disposée dans le plan de symétrie P de l'élément profilé 1 grâce à ses boucles inférieures 7 qui sont déviées et se positionnent de part et d'autre des câbles de précontrainte ou des armatures principales 8 sans interférence.With reference to the figures, the production mold 10, 20 according to the invention is intended for the factory molding of profiled elements 1, based on concrete in particular, prestressed or not, reinforced or not, such as beams or beams called with seam, an example of which is shown in FIG. 1. This profiled element 1 has an inverted T-shape defining a vertical core 2 and two lateral wings 3. It comprises a surpassing armature 5 called seam whose function is to provide better attachment to the concrete floor cast on site in accordance with seismic standards. This protruding frame 5 may be formed of straight vertical steel rods, hook or in any other form. It may also be formed of U-shaped or sinusoidal steel wires as illustrated in FIGS. 2A to 2C. FIG. 2A illustrates a simple sinusoidal armature 5a, FIG. 2B illustrates a simple sinusoidal 5b armature supplemented with a central jackframe 6 and FIG. 2C illustrates a simple sinusoidal armature 5c whose lower loops 7 are deflected on both sides. of the plane of symmetry P. In the case of the manufacture of prestressed or reinforced profiled elements 1, that is to say having in their middle part prestressing tendons or main reinforcement 8 (see FIG. protruding frames 5a, 5b of FIGS. 2A and 2B are offset with respect to the plane of symmetry P of the profiled element 1 so as not to interfere with these prestressing or main reinforcement cables 8. The protruding frame 5c of FIG. 2C is designed to be arranged in the plane of symmetry P of the profiled element 1 by virtue of its lower loops 7 which are deflected and positioned on either side of the precontrol cables nte or main frames 8 without interference.

Plusieurs manières de réaliser l'invention :Several ways to realize the invention:

Le moule de fabrication 10 illustré partiellement aux figures 3A et 3B comporte un coffrage 11, de préférence métallique, ouvert en partie supérieure, en forme de T, dont la section est complémentaire et inversée à celle de l'élément profilé 1 à fabriquer. Les parois latérales 11a, 11b du coffrage 11 sont fixes et légèrement inclinées en V pour faciliter le démoulage de l'élément profilé 1. Le fond 12 du coffrage 11 est fixe et peut être lisse ou crénelé pour former par exemple des crans 4 au sommet de l'élément profilé 1 améliorant l'accrochage du béton coulé sur chantier. Le fond 12 du coffrage 11 comporte une ouverture 13, longitudinale, centrée ou décalée par rapport au plan de symétrie P, s'étendant sur au moins une partie du coffrage 11 et destinée à recevoir une armature dépassante 5 introduite sur une partie de sa hauteur. Dans cet exemple, l'armature dépassante 5 qui est représentée correspond à l'armature 5a sinusoïdale simple de la figure 2A. L'ouverture 13 forme une fente filante s'étendant sur pratiquement toute la longueur du coffrage 11, d'une largeur au moins égale au diamètre du fil d'acier formant l'armature dépassante 5. Cette largeur peut être comprise par exemple entre 5 et 10 mm, ces dimensions n'étant pas limitatives. Cette fente filante peut également être remplacée par une série de plusieurs fentes successives réparties sur toute la longueur du coffrage 11 séparées d'un pas correspondant à la période de la sinusoïde de l'armature dépassante 5.The manufacturing mold 10 partially illustrated in Figures 3A and 3B comprises a formwork 11, preferably metal, open at the top, T-shaped, whose section is complementary and inverted to that of the profiled element 1 to be manufactured. The side walls 11a, 11b of the formwork 11 are fixed and slightly inclined V to facilitate the demolding of the profiled element 1. The bottom 12 of the formwork 11 is fixed and can be smooth or crenellated to form for example notches 4 at the top the profiled element 1 improving the attachment of the concrete poured on site. The bottom 12 of the formwork 11 has an opening 13, longitudinal, centered or offset from the plane of symmetry P, extending over at least a portion of the formwork 11 and intended to receive a projecting armature 5 introduced over part of its height. In this example, the protruding armature 5 that is shown corresponds to the simple sinusoidal armature 5a of FIG. 2A. The opening 13 forms a shooting slot extending over substantially the entire length of the formwork 11, a width at least equal to the diameter of the steel wire forming the projecting frame 5. This width can be for example between 5 and 10 mm, these dimensions not being limiting. This shooting slot can also be replaced by a series of several successive slots distributed over the entire length of the formwork 11 separated by a pitch corresponding to the period of the sinusoid of the projecting frame 5.

Le moule 10 comporte des moyens d'obturation 30 disposés à l'extérieur du coffrage 11 et commandés pour être mobiles entre au moins une position ouverte dans laquelle ils libèrent l'ouverture 13 permettant la mise en place de l'armature dépassante 5 avant moulage et son retrait après moulage et une position fermée dans laquelle ils ferment de manière plus ou moins étanche l'ouverture 13 en obturant les espaces résiduels entre les parois de l'ouverture 13 et l'armature dépassante 5.The mold 10 comprises closure means 30 disposed outside the formwork 11 and controlled to be movable between at least one open position in which they release the opening 13 allowing the establishment of the projecting frame 5 before molding and its removal after molding and a closed position in which they close more or less tightly the opening 13 by closing the residual spaces between the walls of the opening 13 and the projecting armature 5.

Dans la réalisation illustrée par les figures 3A et 3B, les moyens d'obturation 30 comportent un organe d'étanchéité 31 longitudinal, disposé à l'extérieur et sous le coffrage 11, d'un côté de l'ouverture 13, et un contre-appui 32 disposé de l'autre côté de cette ouverture 13. Le contre-appui 32 est formé d'une paroi longitudinale s'étendant d'un bord de l'ouverture 13 à l'extérieur du coffrage 11 dans une direction sensiblement perpendiculaire au fond 12. Ce contre-appui 32 comporte dans sa partie inférieure un retour formant une butée basse 33 sur laquelle repose l'armature dépassante 5 lorsqu'elle est introduite dans l'ouverture 13 de manière à maîtriser sa position en hauteur par rapport au coffrage 11 et donc par rapport à l'élément profilé 1 fabriqué.In the embodiment illustrated in FIGS. 3A and 3B, the closure means 30 comprise a longitudinal sealing member 31 disposed outside and under the formwork 11, on one side of the opening 13, and one against -support 32 disposed on the other side of this opening 13. The counter-support 32 is formed of a longitudinal wall extending from one edge of the opening 13 to the outside of the formwork 11 in a substantially perpendicular direction at the bottom 12. This counter-support 32 comprises in its lower part a return forming a bottom stop 33 on which rests the protruding frame 5 when it is introduced into the opening 13 so as to control its position in height relative to the formwork 11 and thus with respect to the profiled element 1 manufactured.

L'organe d'étanchéité 31 est formé d'un boudin ou d'un profilé, totalement ou partiellement plein, réalisé dans un matériau élastique, tel qu'un élastomère, un caoutchouc ou similaire. Il peut être aussi formé d'une lèvre souple droite ou découpée ou d'une tôle 31' métallique découpée pour épouser le profil de l'armature dépassante 5. Il peut encore être formé d'un profilé longitudinal gonflable (non représenté) par un produit gazeux ou liquide tel que de l'air, de l'eau ou similaire.The sealing member 31 is formed of a flange or a section, totally or partially solid, made of an elastic material, such as an elastomer, a rubber or the like. It may also be formed of a straight or cut flexible lip or a cut metal metal plate 31 'to fit the profile of the projecting armature 5. It may also be formed of an inflatable longitudinal section (not shown) by a gaseous or liquid product such as air, water or the like.

Cet organe d'étanchéité 31 est couplé à un support 34, de préférence par un assemblage démontable pour être interchangeable. Cet assemblage peut être un assemblage par emboîtement ou coulissement dans un rail 35, un assemblage par vissage 36 ou similaire. Il peut être aussi assemblé de manière définitive par collage par exemple. Cet organe d'étanchéité 31 est associé à des moyens d'actionnement 50 comportant un bras mobile 51 couplé d'une part au support 34 de l'organe d'étanchéité 31 et d'autre part à un actionneur (non représenté). Ce bras mobile 51 est monté pivotant autour d'un axe fixe 52 pour être déplacé par l'actionneur entre une position ouverte dans laquelle l'organe d'étanchéité 31 est éloigné du contre-appui 32 (voir figure 3A) et une position fermée dans laquelle il est écrasé contre lui (voir figure 3B). L'actionneur est réversible et peut être un vérin, un moteur avec une transmission à crémaillère, un électroaimant ou similaire.This sealing member 31 is coupled to a support 34, preferably by a removable assembly to be interchangeable. This assembly can be an assembly by interlocking or sliding in a rail 35, a screw connection 36 or the like. It can also be assembled permanently by gluing, for example. This sealing member 31 is associated with actuating means 50 comprising a movable arm 51 coupled on the one hand to the support 34 of the sealing member 31 and on the other hand to an actuator (not shown). This movable arm 51 is pivotally mounted about a fixed axis 52 to be displaced by the actuator between an open position in which the sealing member 31 is moved away from the abutment 32 (see FIG. 3A) and a closed position in which he is crushed against him (see Figure 3B). The actuator is reversible and may be a cylinder, a motor with a rack-and-pinion transmission, an electromagnet or the like.

La figure 4 illustre un moule de fabrication 10, en coupe transversale, comportant deux coffrages 11 tels que décrits en référence aux figures 3A et 3B. Ces deux coffrages 11 sont disposés parallèlement et symétriquement sur un châssis 61. Les contre-appuis 32 sont disposés dos à dos. Dans cette configuration, un seul actionneur (non représenté) à deux sorties est suffisant pour commander simultanément les deux bras mobiles 51 des moyens d'actionnement 50. Ces bras mobiles 51 sont couplés au châssis 61 par un axe fixe 52 à l'extrémité d'une potence 62. Dans cette figure, deux organes d'étanchéité 31, 31' différents sont représentés : celui de gauche correspondant au profilé 31 en élastomère des figures 3A et 3B, celui de droite représentant une lèvre ou une tôle 31' métallique découpée en fonction du profil de la sinusoïde de l'armature dépassante 5.Figure 4 illustrates a manufacturing mold 10, in cross section, having two formwork 11 as described with reference to Figures 3A and 3B. These two forms 11 are arranged parallel and symmetrically on a frame 61. The counter-supports 32 are arranged back to back. In this configuration, a single actuator (not shown) with two outputs is sufficient to simultaneously control the two movable arms 51 of the actuating means 50. These movable arms 51 are coupled to the frame 61 by a fixed axis 52 at the end of A bracket 62. In this figure, two different sealing members 31, 31 'are shown: the one on the left corresponding to the elastomer profile 31 of FIGS. 3A and 3B, that on the right representing a lip or metal plate 31 'cut according to the sinusoid profile of the protruding armature 5.

La figure 5 est une vue similaire à celle de la figure 4 et représente un moule de fabrication 70 selon un autre mode de réalisation de l'invention, comportant deux coffrages 21 pourvus chacun de deux parois latérales 21a, 21 b fixes et d'un fond 22 dans lequel est ménagée une ouverture 23. Dans cet exemple, les moyens d'obturation 40 sont fixes, disposés à l'extérieur du coffrage 21 et logés dans l'épaisseur du fond 22. De ce fait, ils ne nécessitent pas d'actionneur mécanique et sont isolés des huiles de coffrage et du béton. Ces moyens d'obturation 40 comportent deux organes d'étanchéité 41 disposés en regard dans les bords opposés de l'ouverture 23. Ces bords comportent chacun un logement 42 en forme de C, dont les ouvertures se font face, apte à recevoir un des organes d'étanchéité 41, monté de manière interchangeable ou définitive. Cet organe d'étanchéité 41 est formé d'un profilé longitudinal gonflable par un produit gazeux ou liquide. Une alimentation (non représentée) commandée en produit gazeux ou liquide est prévue et reliée aux organes d'étanchéité 41. Le châssis 71 du moule 70 comporte une butée basse 72 disposée au droit de chaque ouverture 23 pour maîtriser le positionnement en hauteur des armatures dépassantes 5. Les armatures dépassantes 5 illustrées dans cet exemple correspondent à l'armature 5c de la figure 2C.FIG. 5 is a view similar to that of FIG. 4 and shows a manufacturing mold 70 according to another embodiment of the invention, comprising two formings 21 provided each with two fixed lateral walls 21a, 21b and one bottom 22 in which is formed an opening 23. In this example, the sealing means 40 are fixed, arranged outside the formwork 21 and housed in the thickness of the bottom 22. As a result, they do not require mechanical actuator and are isolated formwork oils and concrete. These closure means 40 comprise two sealing members 41 arranged opposite each other in the opposite edges of the opening 23. These edges each comprise a C-shaped housing 42, the openings of which face each other, capable of receiving one of the sealing members 41, mounted interchangeably or permanently. This sealing member 41 is formed of a longitudinal profile inflatable with a gaseous or liquid product. A feed (not shown) controlled in gaseous or liquid product is provided and connected to the sealing members 41. The frame 71 of the mold 70 comprises a lower stop 72 disposed at the right of each opening 23 to control the positioning in height of the protruding reinforcements 5. The protruding reinforcements 5 illustrated in this example correspond to the frame 5c of FIG. 2C.

La figure 6 est une vue similaire à celle de la figure 4 et représente un moule de fabrication 80, selon encore une autre variante de réalisation, comportant deux coffrages 11 pouvant être similaires à celui des figures 3 et 4. Dans cet exemple, les moyens d'obturation 90 sont fixes et disposés à l'extérieur du coffrage 11, sous l'ouverture 13. De ce fait, ils ne nécessitent aucun actionneur mécanique. Ils comportent un organe d'étanchéité 91 formé d'une multitude d'éléments plus ou moins souples, s'étendant perpendiculairement à l'axe de l'ouverture 13 pour venir en contact sur le contre-appui 32. Cet organe d'étanchéité 91 est conçu de sorte que certains de ses éléments souples se déforment au passage de l'armature dépassante 5 tandis que les autres éléments souples obturent les espaces résiduels entre les parois de l'ouverture 13 et les parois de l'armature dépassante 5. Cet organe d'étanchéité 91 peut être constitué d'une brosse, de lamelles ou de tout autre organe similaire, réalisé dans des matériaux résistant de préférence aux huiles de décoffrage et au béton et disponibles dans le commerce. De préférence, cet organe d'étanchéité 91 est démontable pour être interchangeable et monté dans un support 92 formé de deux parties assemblées par une vis 93. Cet organe d'étanchéité 91 peut être aussi monté dans un support par emboîtement, coulissement ou similaire. Il peut être aussi assemblé de manière définitive par collage ou rivetage. Ce mode de réalisation est le plus simple à réaliser et est particulièrement adapté au moulage de profilés en béton dit auto-plaçant.FIG. 6 is a view similar to that of FIG. 4 and shows a manufacturing mold 80, according to yet another variant embodiment, comprising two forms 11 that can be similar to that of FIGS. 3 and 4. In this example, the means shutter 90 are fixed and disposed outside the formwork 11, under the opening 13. Therefore, they do not require any mechanical actuator. They comprise a sealing member 91 formed of a multitude of more or less flexible elements extending perpendicularly to the axis of the opening 13 to come into contact with the abutment 32. This sealing member 91 is designed so that some of its flexible elements deform at the passage of the projecting frame 5 while the other flexible elements close the residual spaces between the walls of the opening 13 and the walls of the projecting frame 5. This sealing member 91 can consist of a brush, slats or any other similar member, made of materials resistant preferably to formwork oils and concrete and commercially available. Preferably, this sealing member 91 is removable to be interchangeable and mounted in a support 92 formed of two parts assembled by a screw 93. This sealing member 91 can also be mounted in a support by interlocking, sliding or the like. It can also be assembled permanently by gluing or riveting. This embodiment is the simplest to achieve and is particularly suitable for molding concrete sections said self-placing.

Dans le cas de l'armature dépassante 5b illustrée par la figure 2b, l'armature centrale filante 6 peut être positionnée directement sur l'ouverture 13, 23 et contribuer à son obturation et à son étanchéité pour toutes les variantes de moule décrites..In the case of the protruding armature 5b illustrated in FIG. 2b, the central wire frame 6 can be positioned directly on the opening 13, 23 and contribute to its sealing and sealing for all the mold variants described.
