一种新型的预应力筋连接器——可张拉可浮动连接器在多跨预应力混凝土结构施工中，为了减小张拉时的摩擦应力损失，往往要把一些统长的预应力筋先分割成若干段短筋，再逐段张拉逐段连接，最后形成一根连续的预应力筋。这种分段张拉和连接的工艺过程，通常用交叉连接法来实... A new type of prestressed tendon connector—a tensionable and floatable connector. In the construction of multi-span prestressed concrete structures, in order to reduce the frictional stress loss during tensioning, it is often necessary to put some prestressed tendon reinforcements first. Divided into several sections of short ribs, and then connected section by paragraph by paragraph, and finally formed a continuous prestressed tendons. This kind of segmented tensioning and joining process is usually realized by cross-connection method...
