Description

La présente invention concerne un dispositif destiné à assurer l'assemblage et la fixation d'une panne en béton sur une poutre porteuse lors de l'édification d'un bâtiment. AI'heure actuelle, la fixation d'une panne sur sa poutre porteuse s'effectue à l'aide de béton qui est coulé sur le chantier de manière à réaliser un assemblage par clavetage entre ces deux éléments du bâtiment en cours d'édification. Il en résulte que cet assemblage est naturellement définitif et que la désolidarisation d'une panne en béton de sa poutre ne peut être obtenue que par destruction des deux éléments.The present invention relates to a device intended to ensure the assembly and fixing of a concrete purlin on a support beam during the construction of a building. At present, the fixing of a purlin on its support beam is carried out using concrete which is poured on the site so as to carry out an assembly by keying between these two elements of the building being built. It follows that this assembly is naturally final and that the separation of a concrete breakdown from its beam can only be obtained by destruction of the two elements.

La présente invention se propose d'apporter un dispositif d'assemblage mécanique permettant de réaliser des fixations démontables des pannes sur leur poutre porteuse correspondante.The present invention proposes to provide a mechanical assembly device for making removable fastenings of the purlins on their corresponding support beam.

En conséquence, l'invention a pour objet un dispositif conçu de manière à assurer l'assemblage et la fixation réglable d'une panne en béton sur la poutre porteuse caractérisé en ce qu'il comporte une pièce métallique, noyée partiellement dans la panne en béton et faisant saillie à son extrémité extérieure de façon à assurer la fixation par boulonnage de cette partie en saillie sur la poutre porteuse et en ce qu'on prévoit des moyens de liaison de ladite pièce métallique sur la panne correspondante, à l'appui béton de la panne et des moyens pour la reprise des efforts de traction et des efforts tranchants entre ladite pièce métallique et la panne.Consequently, the subject of the invention is a device designed so as to ensure the assembly and the adjustable fixing of a concrete purlin on the support beam, characterized in that it comprises a metal part, partially embedded in the purlin concrete and protruding at its outer end so as to ensure the fixing by bolting of this protruding part on the support beam and in that provision is made for means for connecting said metal part to the corresponding purlin, to the concrete support of the breakdown and of the means for the recovery of the traction forces and of the cutting forces between the said metal part and the breakdown.

Selon une caractéristique de la présente invention, les efforts tranchants sont repris à l'aide d'une épingle traversant un perçage prévu dans ladite pièce métallique, dans son extrémité noyée dans ladite panne et la reprise des efforts de traction est obtenue à l'aide d'une barre d'ancrage noyée dans la panne et en prise dans ledit perçage.According to a characteristic of the present invention, the shearing forces are taken up using a pin passing through a hole provided in said metal part, in its end embedded in said purlin and the resumption of the tensile forces is obtained using an anchor bar embedded in the purlin and engaged in said bore.

Selon la présente invention, les moyens de liaison de ladite pièce métallique à l'appui béton de la panne sont réalisés sous la forme de cadres noyés dans ladite panne et dont une extrémité est soudée sur ladite pièce métallique.According to the present invention, the means for connecting said metal part to the concrete support of the purlin are produced in the form of frames embedded in said purlin and one end of which is welded to said metallic part.

Selon un mode de réalisation préféré de l'invention, ladite pièce métallique est munie, à son extrémité extérieure en saillie, d'une surface supérieure qui est crantée et qui est percée, selon son axe longitudinal par une mortaise permettant un déplacement du boulon de fixation solidaire de la poutre porteuse, pour couvrir les tolérances de pose et de fabrication.According to a preferred embodiment of the invention, said metal part is provided, at its projecting outer end, with an upper surface which is notched and which is pierced, along its longitudinal axis by a mortise allowing movement of the bolt integral fixing of the supporting beam, to cover the installation and manufacturing tolerances.

Selon l'invention, ladite pièce métallique solidaire de la panne est montée par boulonnage sur la poutre porteuse à l'aide d'une contre-plaque métallique crantée venant s'encastrer dans les crans prévus dans ladite pièce métallique, l'ensemble étant bloqué à l'aide d'un écrou indéserrable.According to the invention, said metal part integral with the purlin is mounted by bolting on the support beam using a notched metal counter plate which is embedded in the notches provided in said metal part, the assembly being blocked. using an undesirable nut.

D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence au dessin annexé qui en illustre un exemple de réalisation dépourvu de tout caractère limitatif. Sur le dessin :

  • - la figure est une vue en perspective représentant l'assemblage, selon l'invention d'une panne sur sa poutre porteuse et ;
  • - la figure 2 est une coupe verticale représentant en détail le dispositif d'assemblage objet de la présente invention.
Other characteristics and advantages of the present invention will emerge from the description given below with reference to the appended drawing which illustrates an embodiment thereof devoid of any limiting character. On the drawing :
  • - The figure is a perspective view showing the assembly, according to the invention of a fault on its support beam and;
  • - Figure 2 is a vertical section showing in detail the assembly device object of the present invention.

En se référant au dessin, on voit que le dispositif selon l'invention destiné à assurer un assemblage mécanique réglable et démontable entre une panne en béton 10 et sa poutre porteuse 12 comprend essentiellement une plaque métallique 14, de préférence en acier galvanisé, dont une extrémité 14' est noyée dans la panne en béton 10 et dont l'autre extrémité fait saillie vers la poutre porteuse 12 de manière à assurer l'assemblage de la poutre et de la panne par boulonnage.Referring to the drawing, it can be seen that the device according to the invention intended to ensure an adjustable and removable mechanical assembly between a concrete purlin 10 and its supporting beam 12 essentially comprises a metal plate 14, preferably made of galvanized steel, one of which end 14 'is embedded in the concrete purlin 10 and the other end of which protrudes towards the support beam 12 so as to assemble the beam and the purlin by bolting.

Cette pièce métallique 14 comporte dans son extrémité 14' qui est noyée dans la panne 10, un perçage 16 au travers duquel passe un moyen assurant la reprise des efforts tranchants, ce moyen étant réalisé ici sous la forme d'une épingle 18, et des moyens assurant la reprise des efforts de traction, ces moyens étant réalisés ici sous la forme d'une barre d'ancrage de traction 20.This metal part 14 has at its end 14 'which is embedded in the purlin 10, a bore 16 through which passes a means ensuring the resumption of cutting forces, this means being produced here in the form of a pin 18, and means ensuring the recovery of the traction forces, these means being produced here in the form of a traction anchor bar 20.

Sur la surface supérieure de la pièce métallique 14 au contact de la panne 10, on soude des cadres supérieurs tels que 22 destinés à assurer la liaison de la pièce métallique 14 à l'appui béton de la panne 10.On the upper surface of the metallic part 14 in contact with the purlin 10, upper frames such as 22 are welded intended to ensure the connection of the metallic part 14 to the concrete support of the purlin 10.

Ainsi qu'on le voit sur le dessin, dans ce mode de réalisation préféré de l'invention, la surface supérieure de l'extrémité en saillie de la pièce métallique 14 est crantée et cette pièce métallique 14 est percée selon une mortaise 24 suivant son axe longitudinal. Cette mortaise 24 permet d'assurer un déplacement du boulon de fixation 26 solidaire de la poutre porteuse 12 afin de couvrir les tolérances de pose et de fabrication.As can be seen in the drawing, in this preferred embodiment of the invention, the upper surface of the projecting end of the metal part 14 is notched and this metal part 14 is pierced according to a mortise 24 according to its longitudinal axis. This mortise 24 ensures movement of the fixing bolt 26 secured to the support beam 12 in order to cover the installation and manufacturing tolerances.

La pièce métallique crantée 14 est rendue solidaire de la poutre porteuse 12 à l'aide du boulon 26 par l'intermédiaire d'une contre-plaque métallique 28 de préférence en acier galvanisé, dont la surface, en regard de la surface supérieure crantée de la plaque 14 est pourvue d'un crantage correspondant de manière que cette contre-plaque puisse venir s'encaster sur la surface crantée de la pièce 14, l'ensemble étant ensuite bloqué par un écrou indéserrable 30.The notched metal part 14 is made integral with the support beam 12 by means of the bolt 26 by means of a metal counter plate 28 preferably made of galvanized steel, the surface of which, facing the notched upper surface of the plate 14 is provided with a corresponding notch so that this counter-plate can be fitted onto the notched surface of the part 14, the assembly then being blocked by an undesirable nut 30.
