The wide use of hollow-core slabs in the construction of industrial and civil buildings is promoted by technical characteristics in the form of saving cement consumption up to 30-40 %, reducing the consumption of reinforcing steel 10 times and more, the overlap of spans up to 15-20 m. In Russia there are more than 200 plants of reinforced concrete structures producing hollow-core slabs. The technology of their production is different - from bench technology using pre-stressed forms, to the manufacture of plates on the "tracks". The main disadvantage of the use of manufactured slabs at domestic and foreign enterprises is their ability to perceive only "beam" loads. Meanwhile, giving these products the functions of operation on the console loads can significantly expand the possibility of using these effective structures. The article provides examples of amplification of hollow- core slabs operating on the console loads. Such slabs make it possible with the help of one product to create a support surface for balconies, loggias, bay windows, consoles.
