Способ изготовления предварительно напряженной железобетонной балки, содержащий при бетонировании балки участки арматурных стержней, которые следует подвергнуть предварительному растяжению или сжатию, оставляются обнаженными и после набора бетоном достаточной прочности с помощью навинченных на арматурные стержни муфт осуществляется предварительное сжатие арматуры на сжимаемых от внешней нагрузки участках арматуры и предварительное растяжение - на растянутых, при этом в зоне действия предварительного сжимающего напряжения в арматуре, имеющей сцепление с бетоном, последний не подвергается предварительному растяжению, отличающийся тем, что ток для снижения преднапряжений в арматуре пропускается на ее отдельных участках.A method for manufacturing a prestressed reinforced concrete beam, containing, during concreting of a beam, sections of reinforcing bars that should be subjected to preliminary tension or compression, are left exposed and after concrete has gained sufficient strength with the help of couplings screwed onto reinforcing bars, the reinforcement is precompressed on the reinforcement sections that are compressed from an external load and preliminary tension - on stretched, while in the zone of action of preliminary compressive stress in the reinforcement, which has adhesion to concrete, the latter is not subjected to preliminary tension, characterized in that the current to reduce the prestress in the reinforcement is passed through its individual sections.
