Title
(EN) STEEL PLATE BEAM AND MANUFACTURING METHOD OF SUCH
(FR) POUTRE EN TÔLE D'ACIER ET PROCÉDÉ DE FABRICATION DE CELLE-CI
Abstract
(EN)
The invention relates to a steel plate beam (1 ), which comprises an upper flange (2) having a smaller upper width (W2) and a lower flange (3) having a larger lower width (W3), and two webs (4a, 4b) at a variable or constant width distance (W) from each other, which both are formed of the same web plate (14). The upper flange has a lower surface (5a) facing the lower flange, and the lower flange has an upper surface (6y) facing the upper flange, and said web plate is fastened with upper welds (7) to said lower surface of the upper flange and with first lower welds (8a) to said upper surface of the lower flange.
(FR)
L'invention concerne une poutre en tôle d'acier (1), qui comporte une semelle supérieure (2) ayant une largeur supérieure inférieure (W2) et une semelle inférieure (3) ayant une largeur inférieure supérieure (W3), et deux âmes (4a, 4b) à une distance de largeur variable ou constante (W) l'une par rapport à l'autre, qui sont toutes les deux formées de la même âme pleine (14). La semelle supérieure a une surface inférieure (5a) faisant face à la semelle inférieure, et la semelle inférieure a une surface supérieure (6y) faisant face à la semelle supérieure, et ladite âme pleine est attachée par des soudures supérieures (7) à ladite surface inférieure de la semelle supérieure et par des premières soudures inférieures (8a) à ladite surface supérieure de la semelle inférieure.
