Description

La présente invention concerne le domaine technique de l'incorporation au sein d'une dalle béton, de canalisations faisant partie d'une installation de circulation d'un fluide telle qu'une installation de plomberie, de climatisation, de chauffage ou de gaz.The present invention relates to the technical field of the incorporation within a concrete slab, of pipes forming part of a circulation installation of a fluid such as a plumbing, air conditioning, heating or gas installation.

Dans le domaine ci-dessus, il est connu de faire passer des canalisations ou tubes pour la circulation d'un fluide à l'intérieur de gaines ou de fourreaux de protection qui sont disposés dans le coffrage d'une dalle avant le coulage du béton. Classiquement, ces fourreaux doivent après séchage du béton, être accessibles à partir de la face supérieure de la dalle afin de permettre leur reprise pour y introduire des tubes de circulation d'un fluide.In the above field, it is known to pass pipes or tubes for the circulation of a fluid inside sheaths or protective sheaths which are arranged in the formwork of a slab before pouring concrete . Conventionally, these sleeves must after drying concrete, be accessible from the upper face of the slab to allow their recovery to introduce fluid circulation tubes.

Pour permettre la reprise de ces fourreaux, il est connu de positionner sur le coffrage de la dalle, les fourreaux dont les extrémités sont insérées par exemple dans un bloc de polystyrène ou comme décrit par le brevet FR 2 789 711 dans une boîte de réservation. Après le coulage et le séchage du béton, le bloc de polystyrène est détruit ou le couvercle de la boîte de réservation est retiré permettant ainsi de libérer l'extrémité des fourreaux. Il est ainsi possible de préserver la liberté des extrémités d'un fourreau incorporé dans une dalle de béton et d'assurer l'accessibilité de ces extrémités à partir de la face supérieure de la dalle. Après le passage des tubes dans les fourreaux de la dalle, du béton est coulé à l'intérieur des boîtes ou de l'espace laissé libre par le bloc de polystyrène.To allow the recovery of these sleeves, it is known to position on the formwork of the slab, the sleeves whose ends are inserted for example into a block of polystyrene or as described by the patent FR 2 789 711 in a booking box. After casting and drying the concrete, the block of polystyrene is destroyed or the cover of the reservation box is removed thus releasing the end of the sleeves. It is thus possible to preserve the freedom of the ends of a sleeve embedded in a concrete slab and to ensure the accessibility of these ends from the upper face of the slab. After the passage of the tubes in the slabs of the slab, concrete is poured inside the boxes or the space left free by the polystyrene block.

Une telle technique donne satisfaction en pratique. Toutefois, il doit être considéré que de telles boîtes généralement réalisées en matière plastique restent à demeure intégrées dans la dalle de béton. Or, le recyclage d'une telle dalle s'avère délicate à mener à bien dans la mesure où cette dalle présente du béton dans lequel de la matière plastique est incluse. Par ailleurs, l'incorporation d'une telle boîte dans la dalle pose quelquefois un problème de finition au niveau de la surface supérieure de la dalle. En effet, la présence de cette boîte empêche d'obtenir une surface lisse entre la partie du béton venant combler l'intérieur de la boîte et la surface supérieure de la dalle.Such a technique is satisfactory in practice. However, it should be considered that such boxes generally made of plastic remain permanently embedded in the concrete slab. However, the recycling of such a slab proves tricky to carry out to the extent that this slab has concrete in which plastic is included. Moreover, the incorporation of such a box in the slab sometimes poses a problem of finishing at the upper surface of the slab. Indeed, the presence of this box prevents a smooth surface between the concrete part to fill the inside of the box and the upper surface of the slab.

La demande de brevet FR 2 722 818 décrit un dispositif de réservation de gaines comportant un récipient ou une boîte réutilisable. Cette boîte est munie de moyens d'ancrage dans une dalle de construction. Ces moyens d'ancrage sont constitués par des pieds vissés dans le fond du récipient et munis de fers à béton.The patent application FR 2,722,818 discloses a duct reservation device comprising a reusable container or box. This box is provided with anchoring means in a building slab. These anchoring means are constituted by feet screwed into the bottom of the container and provided with reinforcing bars.

Le retrait d'une telle boîte après le coulage du béton s'avère délicate à mener à bien en raison de la mise en oeuvre d'un système vis-écrou et du possible blocage qui en découle. Par ailleurs, une telle boîte s'avère difficile en pratique, à fixer aux armatures positionnées dans la dalle de construction.The removal of such a box after pouring the concrete is difficult to carry out because of the implementation of a screw-nut system and possible blockage resulting therefrom. Moreover, such a box proves difficult in practice, to fix the frames positioned in the building slab.

La présente invention vise à remédier aux inconvénients ci-dessus en proposant une solution pour permettre l'incorporation simple et rapide dans une dalle béton de canalisations, tout en facilitant les opérations ultérieures de finition et de recyclage d'une dalle béton réalisée avec une telle boîte de réservation.The present invention aims to overcome the above drawbacks by proposing a solution to allow easy and quick incorporation into a concrete slab pipe, while facilitating subsequent operations of finishing and recycling of a concrete slab made with such booking box.

La présente invention vise à proposer une boîte de réservation conçue pour être positionnée correctement et facilement tout en étant extraite facilement après le coulage et le séchage du béton.The present invention aims to provide a reservation box designed to be positioned correctly and easily while being extracted easily after pouring and drying the concrete.

Comme cela apparaît plus précisément aux Fig. 1 à 3 , l'objet de l'invention concerne une boîte de réservation 1 se présentant sous la forme d'un corps creux 2 comportant un fond 3 pourvu extérieurement d'au moins trois et de préférence cinq pieds 4 d'appui sur un coffrage C tel que cela sera illustré dans la suite de la description. Dans l'exemple illustré, le fond 3 possède une forme de quadrilatère. Les pieds d'appui 4 sont situés à chaque coin du fond 3 et au centre de ce dernier.As it appears more specifically to Fig. 1 to 3 The object of the invention relates to a reservation one box in the form of a hollow body 2 having a bottom 3 provided externally with at least three and preferably five feet 4 for resting on a casing C as that will be illustrated in the following description. In the example illustrated, the background 3 has a quadrilateral shape. The support feet 4 are located at each corner of the bottom 3 and in the center of the latter.

Le corps creux 2 comporte également une paroi latérale 6 s'élevant à partir du fond 3 délimitant à l'opposé du fond 3, une ouverture 8 destinée à être obturée par un couvercle 9. Le couvercle 9 est réalisé pour venir s'emboîter sur le bord supérieur de la paroi latérale 6. Le couvercle 9 est pourvu de picots 91 délimitant entre eux une gorge de passage et de maintien de liens de fixation de la boîte. Le corps creux 2 peut présenter tout autre forme extérieure appropriée à sa fonction et présente dans l'exemple préféré illustré, une forme sensiblement hexaédrique de sorte que la paroi latérale 6 comporte quatre faces 61 à 64. Selon une variante préférée de réalisation, la paroi latérale 6 présente une forme en dépouille convergente vers le fond 3. Ainsi, le corps 2 présente une forme tronc pyramidale convergent vers le fond 3. The hollow body 2 also comprises a side wall 6 rising from the bottom 3 delimiting opposite the bottom 3, an opening 8 to be closed by a cover 9. The cover 9 is made to fit on the upper edge of the side wall 6. The cover 9 is provided with pins 9 1 delimiting between them a groove for passage and maintenance of fastening links of the box. The hollow body 2 may have any other external shape appropriate to its function and present in the preferred example shown, a substantially hexahedral shape so that the side wall 6 has four faces 6 1 to 6 4 . According to a preferred embodiment, the side wall 6 has a flush shape converging toward the bottom 3. Thus, the body 2 has a truncated pyramidal shape converging towards the bottom 3.

De manière classique, la paroi latérale 6 est pourvue de moyens 11 de passage pour au moins un fourreau 12 de protection d'une canalisation (Fig. 5 et 6 ). Avantageusement, une seule face par exemple 61 de la paroi latérale présente des moyens 11 pour le passage de plusieurs fourreaux de protection par exemple au nombre de cinq dans l'exemple illustré (Fig. 2). Bien entendu, cette face 6 1 peut présenter des moyens de passage 11 pour un nombre supérieur ou inférieur de canalisations. De même, chacune des faces 6 1 à 6 4 de la paroi latérale 6 peut présenter des moyens de passage 11 pour un ou plusieurs fourreaux de protection de canalisations.In a conventional manner, the side wall 6 is provided with means 11 for passing at least one sleeve 12 for protecting a pipe ( Fig. 5 and 6 ). Advantageously, a single face for example 6 1 of the wall side has means 11 for the passage of several protective sleeves, for example five in number in the illustrated example ( Fig. 2 ). Of course, this face 6 1 may have passage means 11 for a greater or smaller number of pipes. Similarly, each of the faces 6 1 to 6 4 of the side wall 6 may have passage means 11 for one or more duct protection sleeves.

Les moyens de passage 11 sont par exemple constitués pour chaque fourreau, par une région découpée, prédécoupée ou perforable aménagée dans la paroi latérale 6 pour présenter une moindre résistance à la rupture que le reste de la paroi latérale. De manière préférée mais non exclusive, cette région perforable possède une forme annulaire d'un diamètre inférieur ou égal au diamètre nominal du fourreau à incorporer de façon à permettre, après ouverture, un blocage relatif du fourreau par coincement. De même, cette région perforable peut prédéfinir plusieurs diamètres de passage pour autoriser l'usage de fourreaux de divers diamètres. Les moyens de passage 11 pourrait être réalisés de toute manière appropriée telle que par exemple par un perçage directement exécuté dans la paroi latérale 6 et obturé au moyen d'un bouchon amovible réalisé par exemple dans un matériau élastiquement déformable.The passage means 11 are for example constituted for each sheath, by a cut, pre-cut or perforable region arranged in the side wall 6 to have a lower breaking strength than the rest of the side wall. Preferably, but not exclusively, this pierceable region has an annular shape with a diameter less than or equal to the nominal diameter of the sheath to be incorporated so as to allow, after opening, a relative locking of the sheath by wedging. Similarly, this perforable region can predefine several diameters of passage to allow the use of sleeves of various diameters. The passage means 11 could be made in any appropriate manner such as for example by a bore directly executed in the side wall 6 and closed by means of a removable plug made for example of an elastically deformable material.

Le corps creux 2 comporte également un dispositif 13 d'accrochage de la boîte 1 à une structure de maintien 14 permettant de maintenir en position la boîte lors en particulier du coulage du béton. Dans l'exemple illustré, la structure de maintien 14 comporte des armatures destinées à être incorporées dans la dalle de béton à réaliser. Le dispositif d'accrochage 13 comporte des liens ou des attaches 15 assurant une liaison entre d'une part les armatures 14, et d'autre part le fond 3 et/ou la paroi latérale 6.The hollow body 2 also comprises a device 13 for hooking the box 1 to a holding structure 14 for holding the box in position in particular pouring the concrete. In the illustrated example, the holding structure 14 comprises reinforcements intended to be incorporated in the concrete slab to be produced. The attachment device 13 comprises links or fasteners 15 providing a connection between, on the one hand, the reinforcements 14, and on the other hand the bottom 3 and / or the lateral wall 6.

Dans l'exemple illustré, le système d'accrochage 13 comporte également au moins un crochet, un anneau ou un pontet 16 aménagé pour s'étendre à distance du fond 3 de la boîte et permettant d'assurer le passage d'un lien d'accrochage 15. Chaque anneau 16 comporte ainsi dans l'exemple illustré une forme générale en « U » s'étendant à distance du fond de la boîte 1. Chaque anneau comporte ainsi une âme 161 pourvue à chaque extrémité, d'une branche de liaison 162 au fond 3. Dans l'exemple, le fond 3 est pourvu de quatre anneaux d'accrochage 16 aménagés en relation de chacune des faces 61 à 64. Bien entendu, il est à noter que les anneaux 16 pourraient être aménagés sur la paroi latérale 6. In the example shown, the attachment system 13 also comprises at least one hook, a ring or a bridge 16 arranged to extend away from the bottom 3 of the box and to ensure the passage of a link d 15. Each ring 16 thus comprises in the example shown a general shape in "U" extending away from the bottom of the box 1. Each ring thus comprises a core 16 1 provided with each end, a connecting leg 16 2 bottom 3. In the example, the bottom 3 is provided with four hooking rings 16 arranged in relation to each of the faces 6 1 to 6 4 . Of course, it should be noted that the rings 16 could be arranged on the side wall 6.

De même, chaque anneau 16 peut être réalisé de manière différente. Ainsi, chaque anneau 16 peut être ouvert et non fermé comme illustré sur les dessins. Dans le même sens, chaque anneau 16 peut être réalisé directement entre deux lumières aménagées de manière voisine dans le fond 3 ou la paroi latérale 6. Similarly, each ring 16 can be made differently. Thus, each ring 16 can be open and not closed as illustrated in the drawings. In the same direction, each ring 16 can be made directly between two lights arranged in a similar way in the bottom 3 or the side wall 6.

Conformément à l'invention, la boîte de réservation 1 comporte un système 17 pour extraire la boîte incorporée dans le béton. Le système d'extraction 17 comporte :

  • pour chaque pied 4, un système 18 de désolidarisation de la boîte 1 par rapport au pied 4,
  • et un système 19 pour supprimer l'accrochage de la boîte 1 par rapport à la structure de maintien 14.
According to the invention, the reservation box 1 comprises a system 17 for extracting the box incorporated in the concrete. The extraction system 17 comprises:
  • for each foot 4, a system 18 for separating the box 1 from the foot 4,
  • and a system 19 for eliminating the attachment of the box 1 with respect to the holding structure 14.

Le système d'extraction 17 permet ainsi après coulage et solidification du béton d'extraire la boîte 1 du béton en considérant que les pieds 4 restent incorporés dans la dalle de béton.The extraction system 17 thus allows after pouring and solidification of the concrete to extract the box 1 of the concrete considering that the feet 4 remain embedded in the concrete slab.

Tel que cela ressort plus précisément des Fig. 2 et 3 , le système de désolidarisation 18 comporte pour chaque pied 4, un téton 21 s'étendant extérieurement à partir du fond 3 de la boîte dans lequel est destiné à être engagé un pied 4. Chaque pied 4 se présente sous la forme d'un fût tubulaire fermé à une extrémité libre 41 destiné à venir en appui sur le coffrage C, et ouvert à l'extrémité opposée 42 pour être engagée sur le téton 21 et venir en butée contre le fond 3 de la boîte 1. Il doit être considéré que l'engagement de chaque pied 4 sur un téton 21 est réalisé de manière que le téton 21 ne se trouve pas en contact avec le béton. A cet effet, chaque pied 4 recouvre complètement le téton 21 en venant en appui sur le fond 3 de la boîte. Il est à noter que l'engagement entre le téton 21 et le pied 4 peut être légèrement serré pour assurer un maintien relatif entre les pieds 4 et la boîte 1. Toutefois, l'assemblage entre chaque téton 21 et le pied 4 est tel qu'un effort de traction exercé sur la boîte alors que les pieds 4 sont maintenus fixes permet une séparation entre la boîte 1 et les pieds 4. Dans l'exemple illustré, chaque téton 21 possède une section circulaire apte à coopérer avec l'alésage délimité à l'intérieur du fût tubulaire du pied, à partir de l'extrémité ouverte 42 .As more specifically Fig. 2 and 3 , the uncoupling system 18 comprises for each foot 4, a pin 21 extending externally from the bottom 3 of the box in which is intended to be engaged a foot 4. Each foot 4 is in the form of a barrel tubular closed at one free end 4 1 intended to come to bear on the casing C, and open at the opposite end 4 2 to be engaged on the pin 21 and abut against the bottom 3 of the box 1. It should be considered that the engagement of each foot 4 on a pin 21 is made so that the pin 21 is not in contact with the concrete. For this purpose, each foot 4 completely covers the stud 21 while bearing on the bottom 3 of the box. It should be noted that the engagement between the pin 21 and the foot 4 can be slightly tightened to ensure relative retention between the feet 4 and the box 1. However, the assembly between each pin 21 and the foot 4 is such that a tensile force exerted on the box while the feet 4 are held fixed allows a separation between the box 1 and the feet 4. In the illustrated example, each pin 21 has a circular section adapted to cooperate with the bore defined inside the tubular shaft of the foot, from the open end 4 2.

Selon une variante préférée de réalisation, chaque pied 4 est pourvu à partir de son extrémité ouverte 42 , d'un épaulement, d'une collerette ou d'une bague 24 s'étendant en saillie par rapport au pied pour venir en appui sur le fond 3 de la boîte. La collerette d'appui 24 permet d'assurer une reprise des efforts susceptibles d'intervenir sur la boîte 1 tout en constituant une barrière d'étanchéité pour le béton par rapport aux tétons 21.According to a preferred embodiment, each foot 4 is provided from its open end 4 2 , a shoulder, a flange or a ring 24 projecting from the foot to bear on the bottom 3 of the box. The support flange 24 makes it possible to take up the forces likely to operate on the box 1 while constituting a sealing barrier for the concrete with respect to the pins 21.

Selon une caractéristique avantageuse de réalisation, le système de suppression 19 de l'accrochage de la boîte 1 à la structure de maintien 14 est accessible par l'intérieur de la boîte 1. Le système de suppression 19 comporte au moins une fenêtre d'accès 28 aménagée dans la paroi latérale 6 ou comme dans l'exemple illustré, dans le fond 3 de la boîte permettant d'accéder aux liens d'accrochage 15 qui assurent la liaison entre la boîte 1 et la structure de maintien 14. Tel que cela apparaît plus précisément sur les Fig. 1 et 2, une fenêtre d'accès 28 est aménagée pour s'étendre au moins en vis-à-vis de chaque anneau d'accrochage 16. Par exemple, chaque fenêtre 28 est aménagée entre les branches 162 de l'anneau pour déboucher en regard de l'âme 161 de l'anneau.According to an advantageous characteristic of realization, the system of suppression 19 of the attachment of the box 1 to the structure of maintenance 14 is accessible by the interior of the box 1. The system of suppression 19 comprises at least an access window 28 arranged in the side wall 6 or as in the example shown, in the bottom 3 of the box to access the attachment links 15 which provide the connection between the box 1 and the holding structure 14. As this appears more precisely on the Fig. 1 and 2 , an access window 28 is arranged to extend at least vis-à-vis each attachment ring 16. For example, each window 28 is arranged between the branches 16 2 of the ring to open against of the soul 16 1 of the ring.

La boîte 1 ainsi constituée est mise en oeuvre conformément à l'invention selon un procédé illustré plus précisément en relation des Fig. 4 à 6 en vue de l'incorporation de canalisations diverses dans une dalle de béton armé.The box 1 thus constituted is used according to the invention according to a method illustrated more precisely in relation to the Fig. 4 to 6 for the incorporation of various pipes in a slab of reinforced concrete.

Avant coulage du béton et après mise en place du coffrage C et de la structure de maintien 14 telle que des armatures métalliques, la boîte 1 est disposée à l'intérieur du coffrage C de manière à placer les pieds 4 en appui sur le fond du coffrage C. La boîte 1 est immobilisée au moyen de liens d'accrochage 15 passés dans les anneaux d'accrochage 16 et autour des armatures 14. Il est à noter que dans cette position, comme cela apparaît plus précisément à la Fig. 5 , les liens d'accrochage 15 sont visibles ou accessibles à partir de l'intérieur de la boîte 1. Il est à noter que la boîte 1 peut être fixée à une structure de maintien 14 différente des armatures telles qu'illustrées sur les dessins. Ainsi, la structure de maintien 14 peut être une partie du coffrage C. Before pouring the concrete and after placing the formwork C and the holding structure 14 such as metal frames, the box 1 is disposed inside the formwork C so as to place the feet 4 resting on the bottom of the C. The box 1 is immobilized by means of fastening links 15 passed in the fastening rings 16 and around the frames 14. It should be noted that in this position, as appears specifically to the Fig. 5 , the attachment links 15 are visible or accessible from the inside of the box 1. It should be noted that the box 1 can be attached to a holding structure 14 different from the frames as illustrated in the drawings. Thus, the holding structure 14 may be a part of the formwork C.

Le procédé selon l'invention fait également intervenir une étape de passage d'au moins un fourreau de protection 12 d'une canalisation à l'intérieur de la boîte par les moyens de passage 11 aménagés dans la paroi latérale 6 de cette dernière. Après mise en place du ou des fourreaux 12, le couvercle 9 est mis en place pour assurer l'obturation de l'ouverture 8 de la boîte 1. The method according to the invention also involves a step of passage of at least one protective sleeve 12 of a pipe inside the box by the passage means 11 arranged in the side wall 6 of the latter. After placing the sleeve (s) 12, the lid 9 is put in place to seal the opening 8 of the box 1.

Le béton destiné à former la dalle 31 est alors coulé de manière que la boîte 1 se trouve entièrement noyée dans la dalle 31. Après séchage du béton, le couvercle 9 est enlevé ainsi qu'éventuellement la couche de béton superficielle recouvrant le couvercle 9. Le procédé selon l'invention consiste alors à extraire la boîte 1 incorporée dans la dalle 31 ( Fig. 6 ). Selon une variante préférée de réalisation, le système 19 de suppression de l'accrochage de la boîte 1 par rapport aux armatures 14 est réalisé en coupant les liens 15 accessibles chacun par la fenêtre d'accès 28 aménagée dans le fond 3 de la boîte. Chaque lien 15 est coupé par exemple par l'intermédiaire d'un outil de coupe permettant de libérer la boîte 1 par rapport aux armatures 14. Il est à noter qu'il pourrait être envisagé également de réaliser les anneaux 16 d'accrochage avec une faible résistance afin d'assurer leur rupture lors de l'application de l'effort de traction. Dans le même sens, il peut être prévu d'utiliser des liens 15 avec une faible résistance pour se casser lors de l'extraction de la boîte.The concrete intended to form the slab 31 is then poured so that the box 1 is entirely embedded in the slab 31. After drying of the concrete, the cover 9 is removed as well as possibly the surface concrete layer covering the cover 9. The method according to the invention then consists in extracting the box 1 incorporated in the slab 31 ( Fig. 6 ). According to a preferred embodiment, the system 19 for removing the attachment of the box 1 relative to the frames 14 is made by cutting the links 15 each accessible by the access window 28 arranged in the bottom 3 of the box. Each link 15 is cut for example by means of a cutting tool for releasing the box 1 relative to the reinforcements 14. It should be noted that it could be envisaged also to make the rings 16 with a snap low resistance to ensure their breakage when applying the tensile force. In the same direction, it may be planned to use links 15 with a low resistance to break during the extraction of the box.

L'extraction de la boîte 1 consiste à exercer un effort de traction sur la boîte 1. L'application de cet effort conduit à la séparation ou à la désolidarisation de la boîte par rapport aux pieds 4 qui restent ancrés dans la dalle 31. L'effort de traction peut être effectué par tout outil adapté pour permettre d'assurer cet effort conduisant à l'extraction de la boîte par rapport à la dalle de béton 31. The extraction of the box 1 is to exert a tensile force on the box 1. The application of this effort leads to the separation or the separation of the box relative to the feet 4 which remain anchored in the slab 31. L Traction effort can be performed by any suitable tool to ensure that this effort leading to the extraction of the box relative to the concrete slab 31.

La Fig. 7 illustre un système d'assemblage 35 permettant de solidariser entre elles, deux boîtes 1 montées côte à côte. Le système d'assemblage 35 comporte une barre de liaison 36 entre les deux pieds 4 appartenant à deux boîtes différentes. La barre de liaison 36 est équipée à chaque extrémité, d'une douille 37 de réception de l'extrémité libre 41 d'un pied 4. Chaque douille de réception 37 possède une forme complémentaire de celle de l'extrémité du pied 4. De préférence, la barre de liaison 36 est pourvue d'un trou 39 permettant le passage d'un organe de fixation dans le coffrage C de la dalle.The Fig. 7 illustrates an assembly system 35 for securing together, two boxes 1 mounted side by side. The assembly system 35 comprises a connecting bar 36 between the two legs 4 belonging to two different boxes. The connecting bar 36 is fitted at each end with a socket 37 for receiving the free end 4 1 of a foot 4. Each receiving socket 37 has a complementary shape to the foot end 4. Preferably, the connecting bar 36 is provided with a hole 39 allowing the passage of a fastener in the formwork C of the slab.
