Claims (6)

1. Предварительно напряженная железобетонная балка с регулируемой силой натяжения для регулирования силы сопротивления нагрузке, состоящая из верхнего фланца, поддерживающего верхний настил моста или здания, смонтированный на нем, корпусной части и нижнего фланца, отличающаяся тем, что указанная предварительно напряженная железобетонная балка содержит натянутые стальные тросы, предусмотренные в продольном направлении указанной балки и натягиваемые для компенсации силы сопротивления нагрузке и, по меньшей мере один или более не натянутых стальных тросов, предусмотренных в продольном направлении указанной балки, так что сила сопротивления нагрузке указанного моста или здания может быть увеличена посредством натяжения указанных не натянутых стальных тросов.1. Pre-stressed reinforced concrete beam with adjustable tension force to regulate the load resistance force, consisting of an upper flange supporting the upper deck of a bridge or building mounted on it, a hull and a lower flange, characterized in that said prestressed concrete beam contains tensioned steel the cables provided in the longitudinal direction of the specified beam and stretched to compensate for the resistance force to the load and at least one or more without tension utyh steel cables provided in a longitudinal direction of said girder, so that the force load resistance of said bridge or building can be increased by tensioning said non-tensioned steel cables. 2. Балка по п.1, отличающаяся тем, что дополнительно содержит открытую вырезанную часть в заданной части в продольном направлении указанной балки и соединительный элемент, установленный в указанной открытой вырезанной части для закрепления одних концов указанных стальных тросов, другие концы которых закреплены в концевой части указанной балки.2. The beam according to claim 1, characterized in that it further comprises an open cut part in a predetermined part in the longitudinal direction of the specified beam and a connecting element mounted in the specified open cut part for securing one ends of these steel cables, the other ends of which are fixed in the end part specified beam. 3. Балка по п.1, отличающаяся тем, что указанный соединительный элемент содержит опорный элемент, имеющий отверстия, образованные в нем, через которые проходят одни концы указанных стальных тросов, другие концы которых закреплены в концевой части указанной балки, и клинья, вставленные между указанным стальным тросом и указанным опорным элементом.3. The beam according to claim 1, characterized in that said connecting element comprises a support element having openings formed therein through which one ends of said steel cables pass, the other ends of which are fixed at the end of said beam, and wedges inserted between the specified steel cable and the specified supporting element. 4. Балка по п.1, отличающаяся тем, что один конец указанного не натянутого стального троса выходит наружу в одной из концевых частей указанной балки для приложения силы натяжения.4. The beam according to claim 1, characterized in that one end of the specified unstretched steel cable comes out in one of the end parts of the specified beam for applying a tensile force. 5. Балка по п.1, отличающаяся тем, что сила сопротивления нагрузке указанного моста или здания может быть увеличена посредством натяжения указанных на натянутых стальных тросов во время сооружения указанной балки и/или после ее сооружения.5. The beam according to claim 1, characterized in that the load resistance force of the specified bridge or building can be increased by tensioning said tensioned steel cables during the construction of the specified beam and / or after its construction. 6. Балка по п.5, отличающаяся тем, что во время сооружения регулируется сила натяжения указанных не натянутых стальных тросов во время или после отливки плиты, и после сооружения сила натяжения указанных не натянутых стальных тросов регулируется во время эксплуатации указанных моста или здания.6. The beam according to claim 5, characterized in that during the construction, the tension force of said unstretched steel cables is regulated during or after casting the plate, and after construction, the tension force of said unstretched steel cables is regulated during operation of said bridge or building.
