A wooden beam (1) has several sections which are subjected to a transversal tension and which affect in particular the areas in which there are recesses or openings (3). Rod-shaped elements are provided in the form of screws (4) which are introduced in such a way that they extend crosswise to the longitudinal direction of the beam (1) in order to absorb this transversal tension. These screws are screwed in from the top side (5) or the underside (6) of the beam (1) and each extend over part of the height (H) of the beam (1) only and are therefore directly associated with the area (2) that is subjected to transversal tension.
