Date Jan. 12, 1995A joist for building constructions includes an oblong body with threaded holes for receiving cylindrical, threaded space and level adjusters that are screwed into the holes to protrude from the joist body and thereby form an air gap with respect to the supporting surface and to adjust the level of the joist body. The threads of the holes are formed directly in the joist body and the space and level adjusters, threaded from end to end, have a length such that a rear portion situated inside the joist body and a front portion have part-lengths that enable a secure thread connection. The space and level adjusters are arranged in the central plane and/or in two rows on each side of the central plane.
