Carving the edges of the trapezoid and flat insertions is done at an angle of (55±3)°. Break-ups during welding branches of longitudinal edges to the floor plate are done with length not less than 200 mm. High strength bolts are tightened by a force which is 60-70% of the designed force. Flat insertions with carved edges are put relative the butt-end walls of the trapezoid longitudinal stringers with a gap not less than 10 mm.EFFECT: simplification of coupling edges when they are misaligned.9 cl, 4 dwg
