The invention relates to a prefabricated joint structure for joining an essentially wooden elongated beam (2) or similar to at least one other beam (2) over a predetermined length (A) of a relatively short joint portion (4) in the beam, the joint (1) being accomplished by means of pins, bolts or similar jointing means (5) penetrating the beam or beams. In each joint there are at least wo jointing means in a direction transverse to the main grain of the beam. The joint structure further comprises a metal nail plate (6), having a plate plane transverse to the length (T) of the jointing means and whose nails (7) protrude from the plate plane and are embedded in the beam wood. On the prefabricated joint portion (4) in each beam (2), at least one single-sided nail plate (6) has been fitted against the outer surface of the beam, the width (W1) of the plate plane of the nail plates in a direction perpendicular to the main beam grain (D) being greater than the distance (W2) between the holes (15) for the two jointing means (5) in this direction, and the nails (7) of the nail plates (6) being embedded in the wood nearly parallel to the jointing means holes. The holes (15) in the jointing means perforate the beams (2) in the area of the plate planes of the nail plates, and they have been mechanised both in the nail plate (6) and in the beam (2) after the nail plates have been fixed to the beam by pressing, in order to provide joint portions (4) retaining dimensional accuracy irrespective of external influences and apt for later assembly into joints (1).
