ZEE BEAM AND METHOD OF ITS MANUFACTURE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; metal structures. SUBSTANCE: in rolling the beam its section is formed so that redistribution of area between wall and belts in proportion of 0.6 - 0.75 per wall and 0.4 - 0.25 per two belts is provided. Wall is connected with belts at acute angle and is tilted relative to vertical through angle θ which is determined by relationship between height, thickness and width of wall and belts. EFFECT: improved quality of zee beam. 2 cl, 2 dwg
