Description

La présente invention a pour objet un caisson pour la mise en attente d'armatures de liaison entre deux parties d'ouvrage en béton.The subject of the present invention is a box for placing connection reinforcements between two concrete structure parts on standby.

La figure 1 montre un caisson de ce type connu par le DE-A-32 22375 au nom de Dôllen. Ce caisson connu est formé par un profilé 2 en forme de tube de section trapézoïdale et muni d'une ouverture longitudinale 3 sur sa face 4 destinée à être placée du côté de la première partie d'ouvrage (non représentée sur le dessin). Ce profilé présente, en outre, sur cette même face 4, des échancrures 5 aptes à recevoir les armatures. Ces échancrures 5 s'étendent sensiblement transversalement à la direction longitudinale du caisson à partir de son ouverture 3.Figure 1 shows a box of this type known by DE-A-32 22375 in the name of Dôllen. This known box is formed by a profile 2 in the form of a trapezoidal section tube and provided with a longitudinal opening 3 on its face 4 intended to be placed on the side of the first part of the structure (not shown in the drawing). This profile also has, on this same face 4, notches 5 suitable for receiving the frames. These notches 5 extend substantially transversely to the longitudinal direction of the box from its opening 3.

Les bords 3a,3b de l'ouverture ont des profils complémentaires en forme de nervure 3a et rainure 3b, de façon à assurer la fermeture du caisson une fois celui-ci mis en place. La section trapézoïdale du profilé est, en outre, prévue de façon que la petite base du trapèze soit constituée par la face 4 du profilé qui est destinée à être placée du côté de la première partie d'ouvrage, c'est-à-dire la face du profilé qui présente les échancrures 5.The edges 3a, 3b of the opening have complementary profiles in the form of rib 3a and groove 3b, so as to ensure the closure of the box once it has been put in place. The trapezoidal section of the profile is also provided so that the small base of the trapezoid is formed by the face 4 of the profile which is intended to be placed on the side of the first part of the work, that is to say the face of the profile which has the notches 5.

Malgré cette section trapézoïdale destinée à en faciliter l'extraction, ce caisson connu ne peut cependant pas être retiré facilement une fois le béton durci et un outil spécial doit être prévu à cet effet.Despite this trapezoidal section intended to facilitate extraction, this known box cannot however be easily removed once the concrete has hardened and a special tool must be provided for this purpose.

En outre, ce caisson doit présenter une épaisseur de paroi assez importante, afin de présenter une rigidité suffisante et est donc coûteux à réaliser du point de vue quantité de matériau.In addition, this box must have a fairly large wall thickness, in order to have sufficient rigidity and is therefore expensive to produce from the point of view of the quantity of material.

Enfin, avec ce type de caisson, la mise en attente d'armatures dites bouclées, c'est-à-dire avec deux brins repliés, nécessite deux caissons, ce qui n'est évidemment pas très commode.Finally, with this type of box, placing so-called looped frames, that is to say with two folded strands, requires two boxes, which is obviously not very convenient.

Le but de la présente invention est de remédier à ces inconvénients et notamment de prévoir un caisson pour la mise en attente d'armatures de liaison du type précité, qui présente en cours d'utilisation une bonne rigidité tout en étant d'une faible épaisseur, qui puisse être extrait facilement et qui permette la mise en attente d'armatures bouclées.The object of the present invention is to remedy these drawbacks, and in particular to provide a box for placing connection reinforcements of the aforementioned type on standby, which has good rigidity while being thin while being in use. , which can be easily extracted and which allows the placing of looped reinforcements.

Ce caisson doit également permettre d'obtenir une meilleure liaison entre les parties d'ouvrage à relier.This box must also make it possible to obtain a better connection between the parts of the structure to be connected.

Ce but est atteint dans le caisson selon l'invention, qui est du type précité, c'est-à-dire du type constitué par un profilé en forme de tube de section polygonale muni d'une ouverture longitudinale sur sa face destinée à être placée du côté de la première partie d'ouvrage et comportant, sur cette même face, des échancrures aptes à recevoir les armatures et s'étendant sensiblement transversalement à la direction longitudinale du caisson, à partir de l'ouverture de celui-ci, en ce que les bords de l'ouverture longitudinale ont en section transversale des profils complémentaires ayant sensiblement la forme de S.This object is achieved in the box according to the invention, which is of the aforementioned type, that is to say of the type constituted by a profile in the form of a tube of polygonal section provided with a longitudinal opening on its face. intended to be placed on the side of the first part of the work and comprising, on this same face, notches capable of receiving the reinforcements and extending substantially transversely to the longitudinal direction of the box, from the opening of the box ci, in that the edges of the longitudinal opening have in cross section complementary profiles having substantially the shape of S.

Ce mode de liaison assure la fermeture du caisson tout en permettant une ouverture plus facile de celui-ci par rapport au caisson connu jusqu'à présent, du fait de la forme des profils complémentaires.This connection mode ensures the closure of the box while allowing easier opening thereof compared to the box known up to now, due to the shape of the complementary profiles.

Avantageusement, le profilé a une section transversale sensiblement trapézoïdale dont la plus grande base est formée par la face du profilé destinée à être placée du côté de la première partie d'ouvrage.Advantageously, the profile has a substantially trapezoidal cross section, the largest base of which is formed by the face of the profile intended to be placed on the side of the first part of the structure.

Cette disposition permet d'avoir entre les deux parties d'ouvrage une zone de liaison en forme de queue d'aronde assurant une meilleure liaison entre ces deux parties d'ouvrage. En outre, le retrait du caisson est toujours possible par simple traction sur le bord de celui-ci, cette traction provoquant tout d'abord la déformation du caisson, et, de ce fait, l'ouverture de celui-ci.This arrangement makes it possible to have a connecting zone in the form of a dovetail between the two parts of the structure ensuring a better connection between these two parts of the structure. In addition, the withdrawal of the box is always possible by simple traction on the edge thereof, this traction first of all causing the deformation of the box, and, therefore, the opening thereof.

Avantageusement aussi, des moyens de retenue et de maintien des armatures sont prévus à l'intérieur du caisson. Ces moyens de maintien permettent non seulement de maintenir les armatures en position à l'intérieur du caisson mais permettent aussi aux armatures de participer à la rigidité de l'ensemble armatures plus caisson, et, par conséquent, de diminuer l'épaisseur de paroi du caisson.Advantageously also, means for retaining and holding the reinforcements are provided inside the box. These holding means not only make it possible to keep the reinforcements in position inside the box but also allow the reinforcements to participate in the rigidity of the set of reinforcements plus box, and, consequently, to reduce the wall thickness of the box.

Ces moyens de maintien peuvent être formés par des languettes élastiques dressées sensiblement verticalement, des saillies, etc.... Ils peuvent également être formés par des languettes s'étendant horizontalement et aptes à séparer deux couches superposées d'armatures.These holding means can be formed by elastic tongues raised substantially vertically, protrusions, etc. They can also be formed by tongues extending horizontally and capable of separating two superposed layers of reinforcements.

Cette forme de réalisation est particulièrement intéressante puisqu'elle permet de mettre en attente dans un même caisson deux couches d'armatures avec un encombrement minimum, ce qui est le cas dans une zone voisine d'une des extrémités du caisson, puisque les brins d'armature de cette zone ne peuvent pas être repliés dans le même sens que les autres, mais nécessairement en sens inverse et doivent donc se superposer aux brins des autres armatures.This embodiment is particularly advantageous since it makes it possible to put two layers of reinforcements in the same box with a minimum space requirement, which is the case in a zone close to one of the ends of the box, since the strands d he reinforcement of this zone cannot be folded in the same direction as the others, but necessarily in opposite direction and must therefore be superimposed on the strands of the other reinforcements.

De toute façon, l'invention sera bien comprise et d'autres caractéristiques seront mises en évidence à l'aide de la description qui suit en référence au dessin schématique annexé représentant à titre d'exemples non limitatifs plusieurs formes de réalisation de ce caisson :

  • Figure 2 est une vue en coupe transversale du caisson selon une première forme de réalisation ;
  • Figures 3 à 5 sont des vues similaires à figure 2 d'autres exemples de réalisation du caisson.
In any case, the invention will be well understood and other characteristics will be highlighted with the aid of the description which follows in reference to the appended schematic drawing showing by way of nonlimiting examples several embodiments of this box:
  • Figure 2 is a cross-sectional view of the box according to a first embodiment;
  • Figures 3 to 5 are views similar to Figure 2 of other embodiments of the box.

Ainsi que le montre notamment la figure 1, le caisson selon l'invention est formé par un profilé 10 ayant sensiblement la forme d'un tube de section trapézoïdale et comportant deux faces 11,12 parallèles et deux faces latérales 13.As shown in particular in FIG. 1, the box according to the invention is formed by a profile 10 having substantially the shape of a tube of trapezoidal section and comprising two parallel faces 11,12 and two lateral faces 13.

Le profilé 10 est ouvert sur toute sa longueur en 8 au niveau de la jonction de sa face 11 avec ses faces latérales 13 et sa face 11 constitue un double volet de fermeture de ces ouvertures 8 en forme de fentes longitudinales du profilé 10, qui est articulé en son milieu sur une paroi de séparation 14 du profilé.The profile 10 is open over its entire length in 8 at the junction of its face 11 with its lateral faces 13 and its face 11 constitutes a double closing flap of these openings 8 in the form of longitudinal slots of the profile 10, which is articulated in its middle on a partition wall 14 of the profile.

Cette face 11 est destinée à être appliquée contre le coffrage de la première partie d'ouvrage 17 et a une dimension transversale supérieure à celle de la face 12 et qui correspond donc à la grande base du trapèze constituant la section transversale du profilé 10.This face 11 is intended to be applied against the formwork of the first part of the work 17 and has a transverse dimension greater than that of the face 12 and which therefore corresponds to the large base of the trapezoid constituting the cross section of the profile 10.

Des échancrures 15, s'étendant transversalement à la direction longitudinale du caisson 10, sont ménagées sur la face 11 du caisson, à partir des bords libres lla de celle-ci, afin de recevoir les armatures 6 devant être mises en attente. Ces échancrures 15 ont la même forme que les échancrures 5 du caisson connu ou ont une forme sensiblement rectangulaire et leurs dimensions correspondent sensiblement au diamètre des armatures devant être mises en attente.Notches 15, extending transversely to the longitudinal direction of the box 10, are provided on the face 11 of the box, from the free edges 11a thereof, in order to receive the frames 6 which have to be put on hold. These notches 15 have the same shape as the notches 5 of the known box or have a substantially rectangular shape and their dimensions correspond substantially to the diameter of the reinforcements to be placed on hold.

On conçoit que ce caisson qui présente deux ouvertures 8 et deux séries d'échancrures 15 permette de mettre en attente deux séries de brins d'armatures 6. Il pourrait bien évidemment ne présenter qu'une seule ouverture et série d'échancrures pour la mise en attente d'une seule série d'armatures à un brin.It is understood that this box which has two openings 8 and two series of notches 15 allows to put on hold two series of strands of frames 6. It could obviously have only one opening and series of notches for setting waiting for a single set of one-strand reinforcement.

Ce caisson 10 comporte également des moyens de retenue et de maintien des armatures 6 dans chaque moitié du caisson.This box 10 also includes means for retaining and holding the frames 6 in each half of the box.

Ces moyens permettent, en outre, d'améliorer, pour une même épaisseur de paroi, la rigidité du caisson, du fait qu'ils permettent aux armatures de participer à la rigidité de l'ensemble armatures plus caisson. Ils sont formés, d'une part, par des saillies 18 formées sur la paroi de séparation médiane 14 du caisson, sur chaque côte de celle-ci, et d'autre part, par des languettes élastiques 16 formées sur la paroi de fond 12 du profilé.These means also make it possible to improve, for the same wall thickness, the rigidity of the box, because they allow the frames to participate in the rigidity of the set of frames plus box. They are formed, on the one hand, by projections 18 formed on the wall of median separation 14 of the box, on each side thereof, and on the other hand, by elastic tabs 16 formed on the bottom wall 12 of the profile.

Les languettes élastiques 16 sont formées à proximité de chaque paroi latérale 13 et sont inclinées en direction de la paroi de séparation 14. Chaque languette 16 présente, en outre, à son extrémité libre une partie saillante 16a inclinée en direction du fond 12.The elastic tongues 16 are formed near each side wall 13 and are inclined in the direction of the partition wall 14. Each tongue 16 has, at its free end, a projecting part 16a inclined in the direction of the bottom 12.

Les saillies 18 et les languettes 16 permettent de maintenir parfaitement en place les armatures 6 dans le caisson 10, quel que soit leur diamètre. En effet, les languettes '16 sont disposées de façon à exercer une pression dirigée à peu près radialement sur la partie repliée 6b de chaque armature. Si l'armature 6 a un diamètre plus grand, comme représenté dans la partie droite de la figure 2, la languette 16 associée s'écartera du fait de son élasticité tout en exerçant une pression sur l'armature tendant à la plaquer contre le fond 12 du caisson 10.The protrusions 18 and the tongues 16 make it possible to keep the reinforcements 6 perfectly in place in the box 10, whatever their diameter. Indeed, the tongues '16 are arranged so as to exert a pressure directed approximately radially on the folded part 6b of each frame. If the frame 6 has a larger diameter, as shown in the right part of FIG. 2, the associated tongue 16 will move away due to its elasticity while exerting pressure on the frame tending to press it against the bottom. 12 of housing 10.

De même, les saillies 18, par leur orientation, visent à empêcher un déplacement des armatures 6 vers le haut.Likewise, the projections 18, by their orientation, aim at preventing an upward movement of the frames 6.

Les bords libres 13a des faces latérales 13 et ceux Il a du volet de fermeture 11 ont des profils complémentaires ayant sensiblement la forme de S. Cette disposition permet d'obtenir une fermeture des ouvertures 18 du caisson 10 par liaison de forme entre les bords de ses faces latérales 13 et de son volet de fermeture 11.The free edges 13a of the lateral faces 13 and those 11a of the closing flap 11 have complementary profiles having substantially the shape of S. This arrangement makes it possible to close the openings 18 of the box 10 by form connection between the edges of its side faces 13 and its closing flap 11.

Chaque armature 6 est mise en place dans le caisson par passage dans son ouverture 8, après élargissement de celle-ci, et introduction de sa partie 6a dans une échancrure 15 associée.Each frame 6 is placed in the box by passing through its opening 8, after widening thereof, and introduction of its part 6a in an associated notch 15.

Le profilé 10 est en un matériau métallique ou plastique, par exemple en chlorure de polyvinyle (PVC) extrudé, présentant une certains élasticité afin de permettre l'élargissement de son ouverture 8 par légère déformation de ses faces latérales 13 et de sa face avant 11.The profile 10 is made of a metallic or plastic material, for example extruded polyvinyl chloride (PVC), having a certain elasticity in order to allow the widening of its opening 8 by slight deformation of its lateral faces 13 and of its front face 11 .

Une fois les armatures 6 mises en place dans le caisson 10 et ses échancrures 15, celui-ci est refermé, afin d'éviter que de la laitance ne s'écoule à l'intérieur lors du coulage du béton par la liaison de forme précitée entre ses bords lla et 13a, cette liaison étant autorisée par l'élasticité du matériau utilisé pour la réalisation du caisson 10.Once the reinforcements 6 have been placed in the box 10 and its notches 15, the latter is closed, in order to prevent laitance from flowing inside during the pouring of the concrete by the aforementioned form of connection. between its edges 11a and 13a, this connection being authorized by the elasticity of the material used for the production of the box 10.

Une fois que la première partie d'ouvrage 17 est coulée et décoffrée, le retrait du caisson 10 s'effectue très facilement, malgré sa forme trapézoïdale particulière, en exerçant une traction dans le sens de la flèche 19 sur sa face inférieure 12. Lors de cette traction, les bords de fermeture 11a,13a se trouvent un premier temps bloqués par la forme en queue d'aronde de l'évidement délimité par le caisson dans la première partie d'ouvrage 17, ce qui provoque une déformation du caisson 10 (non représentée sur le dessin), laquelle déformation donne lieu à une séparation des deux bords de fermeture 11a,13a et donc à l'ouverture du caisson 10.Once the first part of the work 17 is cast and removed, the withdrawal of the casing 10 is very easy, despite its particular trapezoidal shape, by exerting traction in the direction of the arrow 19 on its underside 12. During this pulling, the closing edges 11a, 13a are initially blocked by the dovetail shape of the recess delimited by the box in the first part of the work 17 , which causes a deformation of the box 10 (not shown in the drawing), which deformation gives rise to a separation of the two closing edges 11a, 13a and therefore to the opening of the box 10.

Ce caisson est ensuite retiré complètement en poursuivant l'effort de traction sur sa face 12.This box is then completely removed while continuing the tensile force on its face 12.

On voit donc que la section trapézoïdale (qui est en sens inverse par rapport à celle des caissons connus jusqu'à présent) ne gêne pas le retrait du caisson 10. En outre, elle permet d'avoir entre les deux parties d'ouvrage devant être reliées, une zone de liaison en forme de queue d'aronde, ce qui permet d'assurer une meilleure liaison entre celles-ci.It can therefore be seen that the trapezoidal section (which is in the opposite direction to that of the boxes known up to now) does not hinder the withdrawal of the box 10. In addition, it makes it possible to have between the two parts of the work in front be connected, a connecting area in the form of a dovetail, which ensures a better connection between them.

Bien entendu, la liaison de forme entre les bords libres lla,13a pourrait être réalisée d'une toute autre façon.Of course, the shape connection between the free edges 11a, 13a could be achieved in a completely different way.

Le caisson 20 montré à la figure 3 est destiné plus particulièrement à recevoir des armatures 6 à deux brins ou armatures bouclées.The box 20 shown in FIG. 3 is intended more particularly to receive frames 6 with two strands or looped frames.

Ce caisson 20 a sensiblement la même forme que le caisson 10 et comporte de même que celui-ci deux faces parallèles 21,22 dont l'une 21 constitue un double volet de fermeture, articulé sur une paroi de séparation 24 et muni d'échancrures 25, et deux faces latérales 23. La seule différence entre ce caisson 20 et le caisson 10 réside dans le fait que ses dimensions transversales sont plus importantes du fait que les armatures 6 ne sont pas côte à côte, comme c'est le cas lorsque deux séries d'armatures sont disposées comme montré à la figure 2, mais sont, au contraire, séparées par une certaine distance.This box 20 has substantially the same shape as the box 10 and includes, like the latter, two parallel faces 21, 22, one of which 21 constitutes a double closing flap, articulated on a partition wall 24 and provided with notches. 25, and two side faces 23. The only difference between this box 20 and the box 10 lies in the fact that its transverse dimensions are greater because the frames 6 are not side by side, as is the case when two sets of reinforcements are arranged as shown in Figure 2, but are, on the contrary, separated by a certain distance.

Dans ce cas, deux languettes 26 similaires aux languettes 16 sont prévues dans chaque partie du double caisson 20 pour maintenir chaque partie d'armature 6b, les deux languettes 26 situées d'un même côté de la paroi de séparation 34 étant disposées en antagonisme l'une par rapport à l'autre.In this case, two tongues 26 similar to the tongues 16 are provided in each part of the double box 20 to hold each frame part 6b, the two tongues 26 located on the same side of the partition wall 34 being arranged in antagonism l 'one over the other.

Le caisson 30 montré à la figure 5 est de même que le caisson 20 montré à la figure 3 destiné plus particulièrement à recevoir des armatures à deux brins.The box 30 shown in FIG. 5 is the same as the box 20 shown in FIG. 3 intended more particularly to receive reinforcements with two strands.

Ce caisson 30 a sensiblement la même forme que les caissons 10 et 20 et présente de même que ceux-ci deux faces parallèles 31,32, dont l'une 31 constitue un double volet de fermeture, articulé sur une paroi de séparation 34 et muni d'échancrures 35, et deux faces latérales 33.This box 30 has substantially the same shape as the boxes 10 and 20 and has, like these, two parallel faces 31, 32, one of which 31 constitutes a double closing flap, articulated on a wall of partition 34 and provided with notches 35, and two lateral faces 33.

Dans ce type de caisson, la liaison de forme entre les bords libres 31a et 33a de l'ouverture 8 est réalisée de façon légèrement différente par rapport aux caissons décrits ci-avant.In this type of box, the form connection between the free edges 31a and 33a of the opening 8 is produced in a slightly different manner compared to the boxes described above.

En effet, si, dans ce cas, le bord libre 33a des parois latérales a effectivement un profil en forme de S ; par contre, les bords libres 31a du double volet de fermeture 31 ont la forme d'un L dont la petite branche s'engage dans une des boucles du S formé par le bord libre associé 33a. Bien évidemment, la fermeture et l'ouverture de ce caisson 30 s'effectuent de la même façon que décrite précédemment.Indeed, if, in this case, the free edge 33a of the side walls actually has an S-shaped profile; on the other hand, the free edges 31a of the double closing flap 31 have the shape of an L, the small branch of which engages in one of the loops of the S formed by the associated free edge 33a. Obviously, the closing and opening of this box 30 takes place in the same way as described above.

Dans ce cas également, les parois latérales 33 n'ont pas une forme droite comme dans les exemples précédemment décrits mais présentent extérieurement une certaine concavité 37.In this case also, the side walls 33 do not have a straight shape as in the examples previously described but have a certain concavity 37 on the outside.

Cette concavité permet de faciliter, en l'amorçant, la déformation du caisson lorsqu'une traction est exercée sur son fond 32, afin de le retirer. Elle permet, en outre, de former sur la face interne des parois latérales une (ou plusieurs) saillie 38 similaire aux saillies 18 et coopérant avec une languette 36 similaire aux languettes 16,26 pour assurer le maintien des armatures à l'intérieur du caisson 30.This concavity makes it easier, by priming it, to deform the box when traction is exerted on its bottom 32, in order to remove it. It also makes it possible to form one (or more) protrusion 38 similar to the protrusions 18 and cooperating with a tongue 36 similar to the tongues 16, 26 on the internal face of the side walls to maintain the reinforcements inside the box. 30.

On notera, en outre, que des évidements 31b longitudinaux sont ménagés le long de la paroi 31 formant volet de fermeture, de chaque côté de la paroi de séparation 34 de façon à former des voiles de matière facilitant la double "articulation" de ce volet de fermeture 31 sur cette paroi 34.It will be noted, moreover, that longitudinal recesses 31b are formed along the wall 31 forming a closing flap, on each side of the partition wall 34 so as to form webs of material facilitating the double "articulation" of this flap closure 31 on this wall 34.

Enfin, dans cet exemple de réalisation, des stries longitudinales 39 sont formées sur la face externe du volet de fermeture 31, afin d'éviter une prise du béton de la première partie d'ouvrage sur la face externe de ce volet et donc afin de faciliter l'extraction de ce caisson 30.Finally, in this exemplary embodiment, longitudinal ridges 39 are formed on the external face of the closing flap 31, in order to prevent the concrete of the first part of the work from setting on the external face of this flap and therefore in order to facilitate the extraction of this box 30.

Le caisson 40 montré à la figure 4 est destiné plus particulièrement à recevoir des armatures 6 à un brin, disposées en deux couches.The box 40 shown in Figure 4 is intended more particularly to receive reinforcements 6 to one strand, arranged in two layers.

Ce caisson 40 présente, de même que les caissons précédemment décrits. deux faces parallèles 41,42 et deux faces latérales 43,44. Cependant. dans ce cas, la face 41 constitue un seul volet de fermeture articulé, également au moyen d'un voile de matière 41b sur l'une 44 des faces latérales, les bords libres respectivement 41a, 43a de la face 41 et de l'autre face latérale 41 délimitant l'ouverture d'introduction 8 des armatures 6.This box 40 has, like the boxes described above. two parallel faces 41,42 and two lateral faces 43,44. However. in this case, the face 41 constitutes a single articulated closing flap, also by means of a veil of material 41b on one 44 of the lateral faces, the free edges 41a, 43a respectively of the face 41 and the other lateral face 41 delimiting the insertion opening 8 of the frames 6.

De même que dans l'exemple de la figure 5, les bords libres 41a.43a de l'ouverture ont des profils complémentaires respectivement en forme de S et en forme de L.As in the example of FIG. 5, the free edges 41a.43a of the opening have complementary profiles respectively in the form of S and in the form of L.

Dans ce cas également, la paroi 43 a sensiblement la même forme concave 47 que les parois 33 du profilé 30, la paroi 44 est par contre sensiblement plane ce qui confère au caisson 40 une section sensiblement rectangulaire.In this case also, the wall 43 has substantially the same concave shape 47 as the walls 33 of the profile 30, the wall 44 is on the other hand substantially planar, which gives the box 40 a substantially rectangular section.

La paroi 41 et la paroi 44 présentent en outre également des stries longitudinales 49 destinées à faciliter l'extraction du caisson.The wall 41 and the wall 44 also further have longitudinal ridges 49 intended to facilitate the extraction of the box.

Enfin, dans le cas de ce caisson 40, les moyens de maintien des armatures sont formés par une languette sensiblement horizontale 46 s'étendant à partir de la paroi 44 sur à peu près la moitié de la section transversale du caisson, à mi-hauteur de celui-ci.Finally, in the case of this box 40, the means for holding the frames are formed by a substantially horizontal tongue 46 extending from the wall 44 over approximately half of the cross section of the box, at mid-height. of it.

Cette languette 46 qui s'étend sur toute la longueur du caisson est à l'état libre (comme montré en traits mixtes sur la figure 4) sensiblement parallèle à la paroi de fond 42 du caisson mais est cependant légèrement inclinée vers le bas, de façon à être repoussée vers le haut par l'introduction d'une armature 6 et à exercer sur celle-ci un effort de maintien suffisant.This tongue 46 which extends over the entire length of the box is in the free state (as shown in phantom in Figure 4) substantially parallel to the bottom wall 42 of the box but is however slightly inclined downwards, so as to be pushed up by the introduction of a frame 6 and to exert on it a sufficient holding force.

Comme le montre la figure, ce caisson permet avec un encombrement minimal la mise en attente de deux couches d'armatures superposées 6,7 séparées l'une de l'autre par la languette 46 et est donc particulièrement avantageux.As shown in the figure, this box allows with minimal space the standby of two layers of superimposed frames 6,7 separated from each other by the tongue 46 and is therefore particularly advantageous.

Comme il va de soi, la présente invention ne se limite pas aux seules formes de réalisation montrées ci-avant à titres d'exemples non limitatifs ; elle en embrasse, au contraire, toutes les variantes d'exécution mettant en oeuvre des moyens similaires ou équivalents.It goes without saying that the present invention is not limited to the sole embodiments shown above by way of nonlimiting examples; on the contrary, it embraces all the variant embodiments using similar or equivalent means.
