The invention relates to a prefabricated, concrete flooring slab (1) provided with reinforcement steel (10), and after erection intended to be provided with a screed (4) or like concrete pouring. So that the finished structure shall function as a unit, from the loading aspect, shear forces from the poured concrete (4) must be effectively taken up by the slab (1). For this reason, the slab is provided with recesses (2) at opposing end portions on its upper side, such that when the slab is loaded they can take up shear forces coming from the poured concrete, these recesses being provided with arched reinforcing bars (5, 6) forming lifting eyes and extending up from the bottom of the recesses (2) to a height such that the intended poured concrete (4) will cover the lifting eyes. |
