Bridge prestressed steel beam connecting structure and construction method
The invention discloses a bridge prestressed steel beam connecting structure and a construction method. The bridge prestressed steel beam connecting structure comprises an anchor plate for connecting a front-section prestressed steel beam and a rear-section prestressed steel beam, and further comprises a connector protection cover for shaping the rear-section prestressed steel beam; the device further comprises an adjusting plate located between the anchor plate and the connector protection cover, the adjusting plate can be movably arranged on the rear-section prestressed steel beam in a limited mode, a plurality of adjusting holes arranged at intervals are formed in the adjusting plate, and the number of the adjusting holes in the adjusting plate is not smaller than that of steel strands in the rear-section prestressed steel beam. Each steel strand in the rear-section prestressed steel beam is arranged in a corresponding adjusting hole in the adjusting plate in a penetrating manner; the multiple adjusting plates are arranged at intervals in the extension direction of the rear-section prestressed steel beam, and the multiple adjusting plates are used for specifying the shape of the rear-section prestressed steel beam; the angle of the prestressed steel beam with large angle change can be adjusted and regulated, the angle-adjustable connecting effect is achieved, stress concentration at the joint of the two sections of steel beams is reduced, and the connecting reliability of the two sections of steel beams is improved.
本发明公开了一种桥梁预应力钢束连接构造及施工方法，包括将前段预应力钢束和后段预应力钢束连接的锚板，还包括将后段预应力钢束整形的连接器保护罩；还包括位于锚板和连接器保护罩之间的调节板，所述调节板可被限位的活动设置在后段预应力钢束上，所述调节板上具有若干个间隔布置的调节孔，所述调节板上的调节孔数量不低于后段预应力钢束中钢绞线的根数，后段预应力钢束中的每根钢绞线穿设于调节板上对应的一个调节孔；所述调节板为沿后段预应力钢束延伸方向间隔布置的若干个，若干个所述调节板用于规定后段预应力钢束的形状；能够对于角度变化较大的预应力钢束，调整并规定角度，起到角度可调的连接作用，降低两段钢束连接处的应力集中，提高两段钢束的连接可靠性。
