Abstract: This invention relates to a device for joining two building units one of which is load-bearing and the other load-imposing. A conventional solution for joining e.g. a column and a beam is to form a sideward projection in the column for supporting the beam. This kind of projection complicates considerably the casting of the column and remarkable shearing forces are formed therein. In the invention these drawbacks are eliminated by fastening to the building units anchoring means which do not project from the column, at least not from the side surfaces thereof, and by positioning them in the building units in such a way that points at which the anchoring means extending from one building unit to the other are fastened to the building units are positioned in a completed joint at a distance from each other in the vertical direction.
