Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne le domaine de la construction de plancher, dalle ou mur en béton et vise plus particulièrement une nouvelle structure de caisson permettant de réaliser une boîte d'attente.The invention relates to the field of concrete floor, slab or wall construction and more particularly to a new box structure for making a waiting box.

De façon connue, une boîte d'attente est un dispositif permettant de masquer temporairement des armatures de liaison entre deux parties d'un ouvrage réalisé en béton armé. Un tel dispositif permet donc de protéger les extrémités repliées des armatures lors de la coulée d'un premier ouvrage. Il permet donc de maintenir apparente une partie des armatures de liaison qui sera ensuite noyée dans le béton d'un second ouvrage en béton.In a known manner, a waiting box is a device for temporarily hiding reinforcement links between two parts of a structure made of reinforced concrete. Such a device thus makes it possible to protect the folded ends of the reinforcements during the casting of a first work. It thus makes it possible to maintain apparent part of the reinforcing links which will then be embedded in the concrete of a second concrete structure.

ART ANTERIEURPRIOR ART

De manière connue, lors de la construction d'un édifice comportant plusieurs ouvrages en béton armé, notamment murs ou dalles, on positionne sur les extrémités supérieures ou latérales de ces éléments d'ouvrage, des armatures métalliques destinées à assurer une liaison mécanique avec les éléments adjacents, et ainsi conférer une cohésion à l'ensemble.In a known manner, during the construction of a building comprising a plurality of reinforced concrete structures, in particular walls or slabs, metal reinforcements are placed on the upper or lateral ends of these structural elements to provide a mechanical connection with the structures. adjacent elements, and thus confer cohesion to the whole.

Ces armatures métalliques comportent une partie qui est noyée dans le premier élément, et une seconde partie qui sera noyée dans l'élément adjacent lors de sa réalisation, notamment lors du coulage du béton.These metal reinforcements comprise a part which is embedded in the first element, and a second part which will be embedded in the adjacent element during its realization, in particular during the pouring of the concrete.

Ces armatures doivent être maintenues en place lors du coulage du béton de réalisation du premier élément, et sont généralement partiellement contenues à l'intérieur d'un dispositif appelé boîte d'attente, constitué d'un caisson qui renferme les extrémités repliées des armatures, tout en laissant apparente la partie des armatures qui sera noyée dans le béton du premier élément.These reinforcements must be held in place during the pouring of the concrete of realization of the first element, and are generally partially contained inside a device called waiting box, constituted of a box which encloses the folded ends of the reinforcements, while leaving exposed the part of the reinforcement that will be embedded in the concrete of the first element.

Après avoir coulé le béton du premier élément, on élimine tout ou partie de la boîte d'attente pour faire apparaître les extrémités des armatures qui ont été isolées du béton, et on déplie les extrémités repliées de ces armatures, destinées à être noyées à l'intérieur de l'élément adjacent en béton.After casting the concrete of the first element, it eliminates all or part of the waiting box to reveal the ends of the reinforcements that have been isolated from the concrete, and unfolded the folded ends of these frames, intended to be embedded in the interior of the adjacent concrete element.

De telles boîtes d'attente sont aujourd'hui largement connues. Ainsi, il en existe en bois, en métal, en carton et également en matière plastique. Lorsque les boites d'attentes sont entièrement extraites du béton, on parle alors de supports et de couvercles amovibles, tels que décrits dans les documents DE 82 01469 U1 , FR 2941 983 et FR 2 712 619 .Such waiting boxes are now widely known. Thus, there are wood, metal, cardboard and also plastic. When the boxes of expectations are entirely extracted from the concrete, one speaks then of supports and removable lids, as described in the documents DE 82 01469 U1 , FR 2941 983 and FR 2,712,619 .

Cependant de telles boites d'attente entièrement amovibles nécessitent des opérations supplémentaires pour les ouvriers qui sont à la fois difficiles et longues à réaliser.However such fully removable waiting boxes require additional operations for workers who are both difficult and time consuming to achieve.

Par ailleurs, l'utilisation de caissons réalisés en acier tels que décrits notamment dans le document FR 2 927 324 se heurte à des inconvénients. En effet, le support perdu présente une masse et un encombrement importants et ne peut être réutilisé puisqu'il reste noyé dans le premier élément d'ouvrage à la jonction entre le premier et le second élément d'ouvrage. Par conséquent, ce type de caisson "consomme" une importante quantité de matière qui est perdu dans le béton et est donc très couteux en utilisation.Furthermore, the use of caissons made of steel as described in particular in the document FR 2 927 324 has disadvantages Indeed, the lost support has a mass and a large size and can not be reused since it remains embedded in the first piece of work at the junction between the first and the second workpiece. Therefore, this type of box "consumes" a large amount of material that is lost in the concrete and is therefore very expensive in use.

De plus, lorsque le matériau utilisé pour réaliser le support perdu est métallique, il se forme des traces d'oxydation visible à la jonction entre les deux éléments en béton. En effet, dans ce cas le support perdu vient affleurer la surface extérieure du premier élément d'ouvrage en béton et est donc en contact avec l'air ambiant. Une telle oxydation est à la fois dommageable sur le plan esthétique et peut se propager en profondeur, altérant ainsi les caractéristiques mécaniques du support perdu.In addition, when the material used to make the lost support is metallic, visible oxidation traces are formed at the junction between the two concrete elements. Indeed, in this case the lost support comes flush with the outer surface of the first concrete workpiece and is therefore in contact with the ambient air. Such oxidation is both aesthetically detrimental and can spread deeply, thus altering the mechanical characteristics of the lost support.

La présente invention a pour objectif de surmonter ces inconvénients.The present invention aims to overcome these disadvantages.

EXPOSE DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention vise donc un caisson de boîte d'attente destiné à permettre la mise en place d'armatures de liaison entre deux éléments d'ouvrage en béton, un tel caisson comportant un support perdu devant être incorporé dans un premier élément d'ouvrage en béton, ce support perdu coopérant avec un couvercle amovible destiné à être retiré une fois le premier élément d'ouvrage en béton réalisé.The invention therefore relates to a box of waiting box intended to allow the establishment of reinforcing links between two concrete work elements, such a box having a lost support to be incorporated in a first work item concrete, this lost support cooperating with a removable cover to be removed once the first piece of concrete made.

Selon l'invention, le caisson se caractérise en ce que :

  • le support perdu est formé une surface principale de forme plane présentant deux rainures rectilignes agencées respectivement chacune le long d'une bordure longitudinale de la surface principale, lesdites deux rainures rectilignes comportant chacune une ouverture agencée au niveau d'une première face du support perdu ;
  • le couvercle amovible comporte une section transversale en forme de U présentant deux ailes chacune comportant une lisière libre coopérant avec une rainure rectiligne du support perdu.
According to the invention, the box is characterized in that :
  • the lost support is formed a planar main surface having two rectilinear grooves each respectively arranged along a longitudinal edge of the main surface, said two rectilinear grooves each having an opening arranged at a first face of the lost support;
  • the removable cover has a U-shaped cross section having two wings each having a free edge cooperating with a rectilinear groove of the lost support.

Autrement dit, le support perdu présente une géométrie plate, dans laquelle vient se positionner la lisière libre du couvercle amovible en forme de U. Ainsi, la quantité de matière perdue dans le coffrage épouse sensiblement la forme d'une tôle plate. Les deux rainures ménagées au niveau des bordures longitudinales de la surface génèrent des excroissances dont la hauteur est comprise entre 6 et 15 millimètres par rapport au plan médian dans lequel est inscrite la surface principale du support perdu.In other words, the lost support has a flat geometry, in which is positioned the free edge of the U-shaped removable cover. Thus, the amount of material lost in the formwork substantially conforms to the shape of a flat sheet. The two grooves formed at the longitudinal edges of the surface generate protrusions whose height is between 6 and 15 millimeters relative to the median plane in which is inscribed the main surface of the lost support.

Par ailleurs, en utilisant différentes longueurs d'ailes au niveau du couvercle amovible, il est possible de réaliser plusieurs boîtes d'attente adaptées pour différentes utilisations. De cette manière, le support perdu peut être commun à une pluralité de boîtes d'attente de différentes tailles en profondeur, au moyen de couvercles amovibles qui peuvent être quant à eux réutilisés. Ceci peut notamment se révéler utile en fonction de la longueur des armatures de liaison qui sont placées à l'intérieur du caisson.Furthermore, by using different lengths of wings at the removable cover, it is possible to make several waiting boxes adapted for different uses. In this way, the lost support may be common to a plurality of different size-in-depth waiting boxes, by means of removable covers which can be reused. This may be useful in particular depending on the length of the connecting armatures which are placed inside the box.

Le matériau pour réaliser un tel caisson de boite d'attente peut avantageusement être métallique. En revanche, pour certaines applications particulières, il peut également être réalisé en tout ou partie dans un matériau polymérique.The material for making such a box of waiting box can advantageously be metallic. On the other hand, for certain particular applications, it can also be made wholly or partly in a polymeric material.

Avantageusement, le support perdu peut comporter une portion centrale agencée en contre-dépouille au niveau d'une seconde face opposée à la première face du support perdu.Advantageously, the lost support may comprise a central portion arranged undercut at a second face opposite to the first face of the lost support.

Ainsi, la portion centrale permet de réaliser un ancrage du support perdu à l'intérieur du premier élément d'ouvrage en béton. Une telle portion centrale peut notamment se présenter sous la forme d'une queue d'aronde garantissant le bon maintien en position du support perdu dans cet élément d'ouvrage en béton.Thus, the central portion makes it possible to anchor the lost support inside the first concrete structure element. Such a central portion may in particular be in the form of a dovetail ensuring the proper holding in position of the lost support in this concrete workpiece.

En pratique, les deux rainures rectilignes peuvent être agencées en contre-dépouille au niveau de ladite seconde face du support perdu.In practice, the two rectilinear grooves may be arranged undercut at the level of said second face of the lost support.

En d'autres termes, les deux rainures rectilignes participent également à l'ancrage et au maintien en position du support perdu à l'intérieur du premier élément d'ouvrage en béton. De cette manière, le support perdu est à la fois ancré au niveau de ses bordures et de sa partie centrale dans le premier élément d'ouvrage en béton.In other words, the two rectilinear grooves also participate in the anchoring and holding in position of the lost support inside the first concrete element. In this way, the lost support is anchored at the level of its borders and its central portion in the first concrete element.

Selon un mode de réalisation particulier, la surface principale du support perdu peut comporter une pluralité de déformations émergeant alternativement au niveau de la première face et de la seconde face du support perdu.According to a particular embodiment, the main surface of the lost support may comprise a plurality of deformations emerging alternately at the first face and the second face of the lost support.

De cette manière, les déformations permettent d'éliminer tout mouvement de rotation ou de translation dans le plan défini par la surface principale du support perdu. En effet, les déformations émergeant alternativement de part et d'autre de cette surface plane, cela génère une pluralité de points d'ancrage, de forme sensiblement conique et orientée dans les deux directions perpendiculaires au plan défini par la surface principale du support perdu.In this way, the deformations make it possible to eliminate any rotational or translational movement in the plane defined by the main surface of the lost support. Indeed, the deformations emerging alternately on either side of this flat surface, this generates a plurality of anchoring points, of substantially conical shape and oriented in both directions perpendicular to the plane defined by the main surface of the lost support.

De plus, les déformations peuvent être agencées symétriquement de part et d'autre de la portion centrale.In addition, the deformations can be arranged symmetrically on either side of the central portion.

Un tel agencement permet en effet de garantir un ancrage équilibré quelque soit la direction de sollicitation du support perdu par rapport à l'un ou l'autre des deux éléments d'ouvrage en béton avec lesquels il coopère.Such an arrangement makes it possible to ensure a balanced anchoring regardless of the direction of stress of the lost support relative to one or the other of the two concretework elements with which it cooperates.

Avantageusement, la surface principale du support perdu peut comporter une pluralité d'ouvertures permettant le positionnement des armatures de liaison au travers du support perdu.Advantageously, the main surface of the lost support may comprise a plurality of openings allowing the positioning of the connection armatures through the lost support.

Autrement dit, les armatures de liaison sont positionnées au travers du support perdu et s'étendent de part et d'autre dudit support. De telles ouvertures peuvent être formées par un trou circulaire ou tout autre type d'ouverture, tel que notamment des ouvertures en étoile, de façon à épouser la périphérie de l'armature de liaison une fois agencée au travers du support perdu.In other words, the connecting armatures are positioned through the lost support and extend on either side of said support. Such openings may be formed by a circular hole or any other type of opening, such as in particular star-shaped openings, so as to conform to the periphery of the connecting reinforcement once arranged through the lost support.

Un tel agencement des ouvertures permet alors de garantir une étanchéité au niveau de cette jonction et évite alors que le béton formant le premier élément d'ouvrage passe au travers de la pluralité d'ouvertures et vienne au niveau de la seconde face du support perdu.Such an arrangement of the openings then makes it possible to guarantee a seal at this junction and thus avoids that the concrete forming the first piece of work passes through the plurality of openings and comes to the level of the second face of the lost support.

En pratique, la portion centrale du support perdu peut comporter des taraudages permettant de solidariser des entretoises munies chacune d'un filetage, les entretoises étant destinées à être agencées en regard de la seconde face du support perdu et permettant de maintenir en position ledit caisson avant la réalisation du premier élément d'ouvrage en béton.In practice, the central portion of the lost support may comprise threads for securing spacers each provided with a thread, the spacers being intended to be arranged opposite the second face of the lost support and to maintain in position said box before the realization of the first concrete workpiece.

Ainsi, les entretoises de compression permettent de maintenir en position le support perdu lors de la coulée du béton formant le premier élément d'ouvrage. Ces entretoises sont alors vissées au moyen d'une portion filetée à l'intérieur des taraudages ménagés dans la portion centrale du support perdu. De tels taraudages peuvent être réalisés directement à l'intérieur de l'épaisseur de la portion centrale ou également être rapportés au moyen d'un insert.Thus, the compression spacers allow to maintain in position the lost support during the casting of the concrete forming the first workpiece. These spacers are then screwed by means of a threaded portion inside the threads formed in the central portion of the lost support. Such threads may be made directly within the thickness of the central portion or may also be reported by means of an insert.

Selon un mode de réalisation particulier, le couvercle amovible peut comporter une excroissance centrale agencée entre les deux ailes, cette excroissance centrale étant sensiblement parallèle aux deux ailes et comportant une autre lisière libre coopérant en liaison appui-plan avec le support perdu.According to a particular embodiment, the removable cover may comprise a central protrusion arranged between the two wings, this central protrusion being substantially parallel to the two wings and having another free edge cooperating in plane support connection with the lost support.

En d'autres termes, l'excroissance centrale positionnée entre les deux ailes garantit une bonne rigidité du caisson de la boîte d'attente et peut ainsi notamment permettre à un utilisateur de marcher sur le caisson sans détériorer le couvercle amovible. En effet, l'excroissance centrale permet de rigidifier la base du couvercle amovible de laquelle émergent les deux ailes sensiblement parallèles à l'excroissance centrale.In other words, the central protrusion positioned between the two wings ensures a good rigidity of the box of the waiting box and can thus in particular allow a user to walk on the box without damaging the removable cover. Indeed, the central protrusion makes it possible to stiffen the base of the removable cover from which emerge the two wings substantially parallel to the central protrusion.

Avantageusement, les deux rainures rectilignes du support perdu peuvent comporter chacune des zones de pincement localisé permettant de maintenir en position par coincement les lisières libres des deux ailes à l'intérieur des rainures rectilignes.Advantageously, the two rectilinear grooves of the lost support may each comprise localized pinching zones to maintain in position by jamming the free edges of the two wings within the rectilinear grooves.

De cette façon, les lisières libres des deux ailes sont maintenues par coincement à l'intérieur des deux rainures rectilignes. De telles zones de coincement localisées peuvent être formées par une déformation ponctuelle du matériau formant le support perdu. De telles déformations peuvent être combinées à des découpes localisées présentant alors des arrêtes vives destinées à "harponner" les lisières libres des deux ailes.In this way, the free edges of the two wings are held by wedging inside the two rectilinear grooves. Such localized wedging zones may be formed by a point deformation of the material forming the lost support. Such deformations can be combined with localized cuts then having sharp edges intended to "harpoon" the free edges of the two wings.

En pratique, la portion centrale du support perdu peut comporter d'autres zones de pincement localisé permettant de maintenir en position par coincement la lisière libre de l'excroissance centrale à l'intérieur de la portion centrale.In practice, the central portion of the lost support may include other localized pinching areas to maintain in position by wedging the free edge of the central protrusion inside the central portion.

De même, les autres zones de pincement localisées permettent d'immobiliser par coincement les lisières libres de l'excroissance centrale à l'intérieur de la portion centrale du support perdu. Ces autres zones de pincement localisées peuvent également être formées par des découpes traversantes à l'intérieur de la portion centrale.Likewise, the other localized pinching zones make it possible to immobilize by jamming the free edges of the central protrusion inside the central portion of the lost support. These other localized pinching areas may also be formed by through cuts within the central portion.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Comme déjà évoqué, l'invention concerne une boîte d'attente permettant de protéger des armatures de liaison lors de la coulée d'un premier élément d'ouvrage en béton.As already mentioned, the invention relates to a waiting box for protecting connecting armatures during the casting of a first concrete workpiece.

Tel que représenté à la figure 1, le caisson de boîte d'attente 10 est donc placé dans un premier élément d'ouvrage en béton 2 de façon à protéger les extrémités d'armatures de liaison 1 à l'intérieur de ce caisson. Une fois que le béton du premier élément d'ouvrage 2 commence à se figer, on retire alors le couvercle amovible du caisson de boîte d'attente. On déforme ensuite les armatures de liaison 1 initialement protégées, pour les placer à l'intérieur du volume dans lequel sera coulé le deuxième élément d'ouvrage en béton 3. As shown in figure 1 , the box of waiting box 10 is placed in a first piece of concrete structure 2 so as to protect the ends of binding frames 1 inside this box. Once the concrete of the first work element 2 begins to freeze, then remove the removable cover of the box box. The bonding armatures 1 initially protected are then deformed and placed inside the volume in which the second concrete element 3 will be cast .

Un tel caisson de boîte d'attente est donc composé d'un couvercle amovible 5 et d'un support perdu 4, restant en place à l'intérieur du premier élément d'ouvrage en béton 2. Such a box of waiting box is composed of a removable cover 5 and a lost support 4, remaining in place inside the first concrete structure element 2.

Tel que représenté dans la figure 2, un tel support perdu 4 présente une surface principale 15 de forme plane et de rainures rectilignes 6, 7, agencées respectivement chacune le long d'une bordure longitudinale 8,9 de la surface principale 15. As shown in the figure 2 such a lost support 4 has a main surface 15 of planar shape and rectilinear grooves 6, 7 respectively arranged along a longitudinal edge 8, 9 of the main surface 15.

Un tel support perdu 4 comporte également une portion centrale 13 et une pluralité de déformation 18, émergeant alternativement de part et d'autre de la surface principale 15 du support perdu 4. De telles déformations 18 peuvent également être agencées symétriquement par rapport à la portion centrale 13. Such a lost support 4 also comprises a central portion 13 and a plurality of deformation 18, emerging alternately on either side of the main surface 15 of the lost support 4. Such deformations 18 may also be arranged symmetrically with respect to the portion Central 13.

De plus, un tel support perdu 4 peut comporter des pluralités d'ouverture 19, permettant le passage d'armatures de liaison 1 au travers de la surface principale 15. In addition, such a lost support 4 may comprise pluralities of opening 19, allowing the passage of connecting armatures 1 through the main surface 15.

Tel que représenté dans la figure 3, le support perdu 4 comporte une première face 14 au niveau de laquelle sont agencées les ouvertures 16 et 17 des rainures rectilignes 6, 7. Par ailleurs, les bordures longitudinales 8 et 9 de la surface principale 15 sont représentées inclinées à environ 45 degrés par rapport au plan défini par la surface principale 15. Un tel agencement permet de garantir une bonne prise dans le premier élément d'ouvrage en béton 2 et garantit ainsi un ancrage du support perdu 4 dans ce premier élément d'ouvrage 2. As shown in the figure 3 , the lost support 4 comprises a first face 14 at which the openings 16 and 17 of the rectilinear grooves 6, 7 are arranged . Moreover, the longitudinal edges 8 and 9 of the main surface 15 are shown inclined at approximately 45 degrees by relative to the plane defined by the main surface 15. Such an arrangement ensures a good grip in the first concrete workpiece 2 and thus ensures anchoring of the lost support 4 in the first workpiece 2.

La seconde face 24 du support perdu 4, présente une portion centrale 13 agencée en contre-dépouille, de façon à garantir un ancrage central du support perdu 4 dans le premier élément d'ouvrage en béton 2. Par ailleurs, les déformations 18, telles qu'elles sont représentées, forment des ondulations émergeant respectivement de part et d'autre de la surface principale 15 au niveau des première et seconde faces 14, 24 du support perdu 4. The second face 24 of the lost support 4, has a central portion 13 arranged undercut, so as to ensure a central anchoring of the lost support 4 in the first piece of concrete structure 2. Moreover, the deformations 18, such they are represented, form undulations emerging respectively on either side of the main surface 15 at the first and second faces 14, 24 of the lost support 4.

Tel que représenté dans la figure 4, le boîtier amovible 5 comporte une section transversale en forme de U présentant une base de laquelle émergent deux ailes 26, 27. Les lisières libres 11, 12 de ces deux ailes 26, 27 coopèrent avec les rainures rectilignes 6, 7 du support perdu 4. As shown in the figure 4 , the removable housing 5 comprises a U-shaped cross section having a base from which two wings 26, 27 emerge. The free edges 11, 12 of these two wings 26, 27 cooperate with the straight grooves 6, 7 of the lost support 4 .

Par ailleurs, des zones de pincement localisées 29 permettent de maintenir par coincement les extrémités libres 11, 12 à l'intérieur des rainures 6, 7. De cette manière, un tel caisson de boîte d'attente est facilement transportable et constitue un ensemble monobloc jusqu'au moment où le couvercle amovible 5 doit être retiré pour permettre la déformation des armatures de liaison.Moreover, localized pinching zones 29 make it possible to maintain by wedging the free ends 11, 12 inside the grooves 6, 7. In this way, such a box of waiting box is easily transportable and constitutes a one-piece assembly until the removable cover 5 must be removed to allow the deformation of the connecting reinforcement.

Par ailleurs, un tel couvercle amovible 5 peut comporter une excroissance centrale 25. Une telle excroissance centrale 25 est alors positionnée entre les deux ailes 26, 27 du couvercle amovible 5 et émerge dans la même direction que les ailes 26, 27 par rapport à la base du U formant le couvercle amovible 5. Moreover, such a removable cover 5 may comprise a central protrusion 25. Such central protuberance 25 is then positioned between the two wings 26, 27 of the removable cover 5 and emerges in the same direction as the wings 26, 27 with respect to the base of the U forming the removable cover 5.

Une telle excroissance centrale 25 présente, quant à elle, une lisière libre 28 coopérant en liaison appui-plan avec le support perdu au niveau de la portion centrale 13. Par ailleurs, tel que précédemment, d'autres zones de pincement localisées 30 permettent de maintenir en position la lisière libre 28 à l'intérieur de la portion centrale 13 du support perdu 4. Such a central protrusion 25 has, for its part, a free edge 28 cooperating in plane-bearing connection with the support lost at the central portion 13. Moreover, as previously, other localized gripping zones 30 make it possible to maintain in position the free edge 28 inside the central portion 13 of the lost support 4.

Tel que représenté, le support perdu 4 peut également comporter des taraudages 20 agencés au niveau de la portion centrale 13 et permettant notamment la fixation d'éléments annexes, tels que des entretoises.As shown, the lost support 4 may also include threads 20 arranged at the central portion 13 and in particular for the attachment of ancillary elements, such as spacers.

Tel que représenté à la figure 5, les éléments de liaison 1 sont positionnés à l'intérieur du caisson de boîte d'attente en pénétrant au travers des ouvertures 19 ménagées dans le support perdu 4. As shown in figure 5 , the connecting elements 1 are positioned inside the box box by penetrating through the openings 19 formed in the lost support 4.

De même, tel que représenté, l'épaisseur du couvercle amovible 5 peut être réduite et, de cette manière, un revers peut être réalisé au niveau des lisières libres 11, 12 des deux ailes 26, 27 de façon à augmenter l'épaisseur du couvercle amovible 5 et garantir le coincement à l'intérieur des rainures rectilignes 6, 7 pouvant comporter des zones de pincement localisées 29. Similarly, as shown, the thickness of the removable cover 5 can be reduced and, in this way, a setback can be made at the level of the free edges 11, 12 of the two wings 26, 27 so as to increase the thickness of the removable cover 5 and guarantee the jamming inside the rectilinear grooves 6, 7 may include localized pinch areas 29.

Tel que représenté à la figure 6, le caisson de boîte d'attente peut donc être associé à des entretoises 21 présentant à une extrémité d'un filetage 20 de façon à coopérer avec les taraudages 22 ménagés dans le support perdu 4. De telles entretoises 21 sont alors agencées en regard de la seconde face 24 du support perdu 4. De telles entretoises de compression 21 permettent alors de maintenir en position et d'éviter les déformations du caisson de boîte d'attente lors de la coulée du béton du premier élément d'ouvrage. De même, des aimants 31, 32 peuvent être agencés au niveau des extrémités du caisson de boîte d'attente pour maintenir en position ledit caisson lors de la coulée du béton du premier élément d'ouvrage.As shown in figure 6 , the box of waiting box can be associated with spacers 21 having at one end of a thread 20 so as to cooperate with the threads 22 formed in the lost support 4. Such spacers 21 are then arranged next to the second face 24 of the lost support 4. Such compression struts 21 then make it possible to maintain in position and to avoid deformations of the waiting box box during the pouring of the concrete of the first workpiece. Similarly, magnets 31, 32 may be arranged at the ends of the box box to hold said box in position during the pouring of the concrete of the first piece of work.

Il ressort de ce qui précède qu'un caisson et une boite d'attente conformes à l'invention présentent de nombreux avantages, et notamment :

  • ils permettent de réaliser des boites d'attente avec un support perdu présentant une masse et un encombrement minimum, engendrant un moindre coût ;
  • ils permettent d'utiliser des couvercles amovibles de différentes hauteurs pour s'adapter à différents types de coffrage avec un unique support perdu ;
  • ils favorisent le décoffrage de cette boîte d'attente ;
  • ils permettent un transport et une manipulation aisés sur chantier, sans risque de déplacement intempestif des armatures de liaison ;
  • ils permettent de définir une zone d'enrobage dont la hauteur est déterminée par la distance séparant le support perdu et le couvercle amovible ;
  • la forme du couvercle amovible et son mode de fixation au support perdu garantissent la non présence d'une partie métallique au niveau de la zone d'enrobage et évitent ainsi la formation d'une éventuelle oxydation ou corrosion.
It follows from the above that a box and a waiting box according to the invention have many advantages, and in particular:
  • they make it possible to make waiting boxes with a lost support having a mass and a minimum size, generating a lower cost;
  • they allow the use of removable covers of different heights to adapt to different types of formwork with a single lost support;
  • they favor the dismantling of this waiting box;
  • they allow easy transport and handling on site, without the risk of inadvertent movement of the connecting reinforcement;
  • they make it possible to define a coating zone whose height is determined by the distance separating the lost support and the removable cover;
  • the shape of the removable cover and its method of attachment to the lost support guarantee the non-presence of a metal part at the coating zone and thus avoid the formation of any oxidation or corrosion.
