    (54) A beam for floor structures


    (57) A floor beam structure comprises a steel beam for a concrete floor which is cast completely or partially on site, and includes a bearing flange and parts which project outwardly therefrom. The invention is characterized in that the steel beam includes the bearing flange (1) and a web-flange (2) which extends perpendicular to the bearing flange. The web-flange is provided, either in or adjacent to its upper edge, with recesses (4) and/or penetrating holes (12) which are intended to cooperate with elongated structural members (3), preferably steel rods or bars, which extend perpendicularly to the web-flange (2) and which are intended to coact with the surrounding concrete (5).
