Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des panneaux muraux préfabriqués et plus particulièrement les dispositifs de levage permettant d'assurer les opérations de levage de tels panneaux.The present invention relates to the field of prefabricated wall panels and more particularly to lifting devices making it possible to carry out lifting operations of such panels.

Un panneau mural préfabriqué est une paroi constituée par une pluralité d'éléments de construction, de forme sensiblement parallélépipédique, assemblés entre eux en un lieu différent du lieu où la paroi est destinée à être installée définitivement. Les éléments de construction seront, dans le présent document, désignés par le terme « brique ».A prefabricated wall panel is a wall made up of a plurality of construction elements, of substantially parallelepiped shape, assembled together in a place different from the place where the wall is intended to be permanently installed. The construction elements will, in this document, be referred to as “brick”.

Après assemblage, un panneau mural préfabriqué être levé pour être chargé dans un moyen de transport qui l'achemine d'un lieu de construction vers un lieu d'installation. Enfin, le panneau mural préfabriqué est de nouveau levé puis posé sur le lieu d'installation.After assembly, a prefabricated wall panel is lifted to be loaded into a means of transport which transports it from a construction location to an installation location. Finally, the prefabricated wall panel is lifted again and placed on the installation site.

Etat de la techniqueState of the art

Afin d'assurer la manutention d'un panneau mural préfabriqué, il est connu d'équiper un tel panneau mural préfabriqué d'une pluralité de dispositifs de levage.In order to ensure the handling of a prefabricated wall panel, it is known to equip such a prefabricated wall panel with a plurality of lifting devices.

Les documents FR3066513 et FR3066484 A1 décrivent un dispositif de levage comprenant entre autres :

  • une embase configurée pour être reçue dans un aménagement défini par au moins une brique d'une rangée de briques du panneau mural préfabriqué, et pour prendre appui contre des parois internes de l'au moins une brique délimitant l'aménagement,
  • deux pattes d'insertion solidaires de l'embase et s'étendant verticalement depuis une face supérieure de l'embase, les deux pattes d'insertion étant configurées pour être engagées dans des alvéoles définies par des parois internes de l'au moins une brique délimitant l'aménagement,
  • un organe de retenue configuré pour être introduit, via un orifice d'insertion débouchant dans une face externe d'une brique, dans des alésages prévus sur les deux pattes d'insertion et dans un élément d'accrochage, tel qu'un oeillet d'accrochage, d'un élément de levage allongé, tel qu'une élingue de levage, s'étendant dans un conduit interne vertical qui est délimité par les rangées de briques formant le panneau mural préfabriqué et qui débouche dans l'aménagement.
The documents FR3066513 And FR3066484 A1 describe a lifting device comprising, among other things:
  • a base configured to be received in a layout defined by at least one brick of a row of bricks of the prefabricated wall panel, and to bear against the internal walls of the at least one brick delimiting the layout,
  • two insertion tabs secured to the base and extending vertically from an upper face of the base, the two insertion tabs being configured to be engaged in cells defined by internal walls of the at least one brick delimiting the development,
  • a retaining member configured to be introduced, via an insertion orifice opening into an external face of a brick, into bores provided on the two insertion lugs and into a hooking element, such as an eyelet hooking, an elongated lifting element, such as a lifting sling, extending in a vertical internal conduit which is delimited by the rows of bricks forming the prefabricated wall panel and which opens into the arrangement.

Un tel dispositif de levage assure un levage aisé et sécurisé d'un panneau mural préfabriqué à l'aide d'un appareil de levage approprié.Such a lifting device ensures easy and safe lifting of a prefabricated wall panel using an appropriate lifting device.

Toutefois, la configuration spécifique du dispositif de levage précité, et en particulier la présence des deux pattes d'insertion qui sont solidaires de l'embase, empêche un retrait de l'embase hors de l'aménagement respectif lorsque le panneau mural préfabriqué repose sur son lieu d'installation, et donc une éventuelle réutilisation de l'embase pour la manutention d'un autre panneau mural préfabriqué.However, the specific configuration of the aforementioned lifting device, and in particular the presence of the two insertion lugs which are integral with the base, prevents removal of the base from the respective arrangement when the prefabricated wall panel rests on its installation location, and therefore a possible reuse of the base for handling another prefabricated wall panel.

A cet effet, la présente invention concerne un dispositif de levage selon la revendication 1 destiné à être rattaché à un élément de levage sensiblement longiligne, tel qu'une élingue de levage ou une barre de levage par exemple, lors d'une opération de levage d'un panneau mural préfabriqué, le dispositif de levage comportant :

  • une pièce d'appui, telle qu'une platine d'appui, configurée pour être reçue de manière amovible dans un aménagement défini par au moins une brique d'une pluralité de rangées de briques formant le panneau mural préfabriqué, et pour prendre appui contre une partie inférieure d'au moins une brique de la pluralité de rangées de briques, la pièce d'appui comportant une ouverture de passage configurée pour être située en regard d'un conduit interne qui est défini par la pluralité de rangées de briques et qui s'étend sensiblement parallèlement à un axe d'élévation du panneau mural préfabriqué, l'ouverture de passage étant configurée pour permettre le passage d'une partie d'extrémité inférieure d'un élément de levage s'étendant dans le conduit interne, et
  • un organe de retenue configuré pour être disposé en dessous de la pièce d'appui et pour s'étendre en travers de l'ouverture de passage, l'organe de retenue étant configuré pour venir en appui contre deux surfaces de butée qui sont prévues sur la face inférieure de la pièce d'appui et qui sont situées de part et d'autre de l'ouverture de passage, l'organe de retenue étant configuré pour être inséré de manière amovible dans un élément d'accrochage, tel qu'un oeillet d'accrochage, une manille d'accrochage ou un crochet, équipant la partie d'extrémité inférieure de l'élément de levage, de telle sorte que, lorsqu'une force de traction est exercée sur l'élément de levage, l'organe de retenue vient en appui contre les deux surfaces de butée prévues sur la pièce d'appui.
For this purpose, the present invention relates to a lifting device according to claim 1 intended to be attached to a substantially elongated lifting element, such as a lifting sling or a lifting bar for example, during a lifting operation of a prefabricated wall panel, the lifting device comprising:
  • a support part, such as a support plate, configured to be removably received in a layout defined by at least one brick of a plurality of rows of bricks forming the prefabricated wall panel, and to rest against a lower part of at least one brick of the plurality of rows of bricks, the support part comprising a passage opening configured to be located opposite an internal conduit which is defined by the plurality of rows of bricks and which extends substantially parallel to an elevation axis of the prefabricated wall panel, the passage opening being configured to allow the passage of a lower end portion of a lifting element extending in the internal conduit, and

In addition, the support piece 8 and the retaining member 17 being removable, it is possible to remove them from the arrangement 7 once the installation has been carried out, in order to reuse the support piece 8 and the retaining member 17 for producing a second prefabricated wall panel for example.

Selon une variante du premier mode de réalisation de l'invention visible sur la figure 7, la pièce d'appui 8 comporte une seule ouverture de verrouillage 19 qui est configurée pour être orientée sensiblement verticalement. Dans cette variante du premier mode de réalisation, la pièce d'appui 8 peut présenter deux trous d'accrochage 16 situés de part et d'autre des première et deuxième parties de liaison 13, 14.According to a variant of the first embodiment of the invention visible on the Figure 7 , the support part 8 comprises a single locking opening 19 which is configured to be oriented substantially vertically. In this variant of the first embodiment, the support part 8 can have two hooking holes 16 located on either side of the first and second connecting parts 13, 14.

Selon une variante du premier mode de réalisation de l'invention spécifiquement représentée sur la figure 8, l'aménagement 7 est configuré pour recevoir uniquement les première et deuxième parties de liaison 13, 14. La première partie d'appui latérale 11 et la deuxième partie d'appui latérale 12 sont situées en dehors de l'aménagement 7, et plus spécifiquement sur la partie inférieure de la brique 2.According to a variant of the first embodiment of the invention specifically represented on the figure 8 , the arrangement 7 is configured to receive only the first and second connecting parts 13, 14. The first lateral support part 11 and the second lateral support part 12 are located outside the arrangement 7, and more specifically on the lower part of brick 2.

Les figures 9 à 11 représentent un dispositif de levage 3 selon un deuxième mode de réalisation de l'invention qui diffère du premier mode de réalisation essentiellement en ce que la pièce d'appui 8 est de forme globalement plane. Avantageusement, et afin de maximiser la surface de contact entre les deux surfaces de butée 18 et l'organe de retenue 17, l'organe de retenue 17 présente alors une section transversale qui est globalement rectangulaire.THE figures 9 to 11 represent a lifting device 3 according to a second embodiment of the invention which differs from the first embodiment essentially in that the support part 8 is of generally planar shape. Advantageously, and in order to maximize the contact surface between the two abutment surfaces 18 and the retaining member 17, the retaining member 17 then has a cross section which is generally rectangular.

Les figures 12 à 14 représentent un dispositif de levage 3 selon troisième mode de réalisation de l'invention qui diffère des premier et deuxième modes de réalisation essentiellement en ce que la pièce d'appui 8 présente globalement une forme de portion de cylindre. Une telle configuration de la pièce d'appui 8 permet une production et une mise en place rapide du dispositif de levage 3. En effet, l'aménagement 7 nécessaire à la mise en place de la pièce d'appui 8 dans le panneau mural préfabriqué 1 peut être réalisé par un simple carottage. Egalement, la forme particulière de la pièce d'appui 8 limite les frottements lors de la mise en place et du retrait de la pièce d'appui 8 à l'intérieur de l'aménagement 7. Par ailleurs, et afin de maximiser la surface de contact entre les deux surfaces de butée 18 et l'organe de retenue 17, l'organe de retenue 17 présente alors une section transversale qui est globalement circulaire.THE figures 12 to 14 represent a lifting device 3 according to third embodiment of the invention which differs from the first and second embodiments essentially in that the support part 8 generally has the shape of a cylinder portion. Such a configuration of the support piece 8 allows rapid production and installation of the lifting device 3. Indeed, the arrangement 7 necessary for the installation of the support piece 8 in the prefabricated wall panel 1 can be carried out by simple coring. Also, the particular shape of the support part 8 limits friction during the installation and removal of the support part 8 inside the arrangement 7. Furthermore, and in order to maximize the surface contact between the two abutment surfaces 18 and the retaining member 17, the retaining member 17 then has a cross section which is generally circular.

Selon un mode de réalisation de l'invention non représenté sur les figures, le dispositif de levage 3 peut en outre être configuré pour effectuer le levage d'un panneau mural préfabriqué 1 réalisé à partir de briques pleines. Dans ce mode de réalisation de l'invention, le conduit interne 10 peut être formé par un ou plusieurs évidements latéraux prévus sur les bords latéraux de deux briques pleines adjacentes. Le conduit interne 10 peut en outre être réalisé par un évidement central ménagé dans une partie centrale d'une brique pleine.According to an embodiment of the invention not shown in the figures, the lifting device 3 can also be configured to lift a prefabricated wall panel 1 made from solid bricks. In this embodiment of the invention, the internal conduit 10 can be formed by one or more lateral recesses provided on the side edges of two adjacent solid bricks. The internal conduit 10 can also be made by a central recess formed in a central part of a solid brick.
