A prefabricated, supporting building structure element, such as wall elements ( 11 ), floor structures ( 47 ) or the like includes a reinforced concrete slab ( 13 ) having a plurality of discrete, parallel, horizontally separated, not mutually joined, longitudinally extended stiffening plate elements ( 15 ), each having a web ( 17 ) with a first longitudinal edge portion ( 21 ) embedded in the concrete, such that a considerable portion of the web ( 17 ) protrudes freely, substantially perpendicularly from a first side defining surface of the concrete slab ( 13 ). The longitudinal edge portion ( 21 ) exhibits a substantially wave shaped corbelling from the plane of the web ( 17 ). |
