Способ армирования предварительно напряженных конструкций пролетных строений путем расположения рабочей напрягаемой арматуры полигонально в узлах перегиба или криволинейных каналах в бетоне, отличающийся тем, что рабочую напрягаемую арматуру располагают полигонально по всей длине неразрезной многопролетной балки, параллельно оси конструкции, при этом каналы для арматуры закладывают по всей длине балок монтируемой конструкции и на стыках составных элементов балок осуществляют соединение каналов, причем соотношение длин соединяемых элементов балок, образующих неразрезную балку, составляет 1 : 0,2 - 0,5 и соотношение высоты балки к длине ее пролета составляет 1 : 25 - 32 соответственно.The method of reinforcing prestressed structures of superstructures by locating the working tensile reinforcement polygonally in the inflection nodes or curved channels in concrete, characterized in that the working tensile reinforcement is placed polygonally along the entire length of the continuous multi-span beam, parallel to the axis of the structure, while the channels for reinforcement are laid along the entire the length of the beams of the mounted structure and at the joints of the constituent elements of the beams carry out the connection of the channels, and the ratio of lengths is connected x components of beams forming the continuous beam is 1: 0.2 - 0.5 and the ratio of the height to the length of its beam span is 1: 25 - 32, respectively.
