(54) Method of joining beam and a beam joint


(57) The invention relates to a method of forming a beam joint and to a beam joint. In the joint, the flanges (2a, 2b) of the beams (1) are connected with a connecting piece (6). Protrusions (4) are formed in the flanges (2a, 2b) of the beams (1) to be joined. The connecting piece (6) connecting the flanges (2a, 2b) comprises recesses at the points corresponding to the protrusions (4) of the flange. Thus, owing to the effect of the protrusions (4) of the flange and the recesses of the connecting piece (6), the beam joint becomes torsion rigid.
