Abstract
L'INVENTION CONCERNE UNE PIECE D'ASSEMBLAGE EN ACIER MOULE POUR LA FORMATION DE NOEUDS DE CONSTRUCTIONS EN CHARPENTE. DANS LA PIECE D'ASSEMBLAGE SUIVANT L'INVENTION, LES EXTREMITES DES POUTRES EN CAISSON SONT ASSEMBLEES L'UNE A L'AUTRE DE MANIERE RIGIDE A LA FLEXION SOUS DIFFERENTS ANGLES, CETTE PIECE COMPORTANT DES CLOISONS S'ETENDANT TRANSVERSALEMENT PAR RAPPORT AU PLAN PRINCIPAL DE LA CHARPENTE POUR ASSURER LE RAIDISSEMENT. LES CLOISONS 14, 15, 16, 17 ONT UNE EPAISSEUR ALLANT EN DIMINUANT EN DIRECTION DU PLAN PRINCIPAL DE LA CHARPENTE. LA PIECE D'ASSEMBLAGE DE L'INVENTION EST UTILISEE POUR REALISER DES CONSTRUCTIONS DE NOEUDS AYANT DE TRES GRANDES DIMENSIONS, PAR EXEMPLE DANS LES CONSTRUCTIONS DE PONTS DE PLATES-FORMES DE FORAGE EN MER.THE INVENTION CONCERNS A MOLDED STEEL ASSEMBLY PART FOR THE FORMING OF KNOTS OF FRAMING CONSTRUCTION. IN THE ASSEMBLY PART FOLLOWING THE INVENTION, THE ENDS OF THE CASING BEAMS ARE ASSEMBLED TO ONE ANOTHER IN A RIGID MANNER BY BENDING UNDER DIFFERENT ANGLES, THIS PART INCLUDING BULKHEADS EXTENDING TRANSVERSALLY WITH RESPECT TO THE MAIN PLANE OF THE FRAMEWORK TO ENSURE THE STRAIGHTENING. THE WALLS 14, 15, 16, 17 HAVE A THICKNESS THAT IS DECREASING TOWARDS THE MAIN PLAN OF THE FRAMEWORK. THE ASSEMBLY PART OF THE INVENTION IS USED TO MAKE CONSTRUCTIONS OF KNOTS HAVING VERY LARGE DIMENSIONS, FOR EXAMPLE IN CONSTRUCTIONS OF BRIDGES OF OFFSHORE DRILLING PLATFORMS.

Toutefois, les principes de construction des deux exemples précités ne suffisent pas pour la réalisation des pièces d'assemblage dans des charpentes comportant de grandes poutres en caisson soudées, car la sollicitation transversale provenant des poutres en caisson exerce une plus forte influence que dans les exemples précités, de sorte que, pour absorber les forces transversales à l'intérieur des noeuds, However, the principles of construction of the two examples mentioned above are not sufficient for the realization of assembly parts in frameworks with large box girders welded, because the transverse stress from the box girders exerts a stronger influence than in the examples mentioned above, so that to absorb the transverse forces inside the knots,
