FIELD: construction.
SUBSTANCE: in a pre-stressed continuous steel reinforced concrete bridge span, comprising a reinforced concrete board combined with a steel beam with the help of high-strength bolts welded to a steel sheet fixed on the steel beam belt via holes arranged in it, and stops built into the board body, the board comprises three separate units with concreted gaps between them and arranged on the steel sheet separated into three separate parts. There are anchor devices in its extreme parts for tension reinforcement, arranged in the form of a bundle of high-strength elements from coal plastic. The method is proposed to implement the device, as well as versions for device implementation.
EFFECT: higher efficiency of concrete operation for tension in a reinforced concrete board above supports, lower metal intensity of a structure, higher strength and reliability of a reinforced concrete board and higher durability of a span as a whole.
