Device for bidirectional tensioning connection of midspan prestressed steel beams of prestressed box girder
The invention provides a prestressed box girder midspan prestressed steel beam two-way tensioning connection device which comprises two opposite prestressed steel beams and further comprises a support arranged above the prestressed steel beams. The connecting assembly comprises two fixed shaft sleeves which are oppositely arranged on the support, the fixed shaft sleeves are in sliding connection with the support, the bottom ends of the fixed shaft sleeves are rotationally connected with rotating pull rods, opening and closing pieces are arranged at the bottom ends of the rotating pull rods, and each opening and closing piece is provided with a clamping end and a clamping end; the connecting anchorage device is arranged at the end of the prestressed steel beam, and the connecting anchorage device is detachably connected with the rotating pull rod through cooperation of the clamping end and the clamping end; and the tensioning piece is arranged between the two rotating pull rods, and the two rotating pull rods oppositely rotate along the coaxial line through the tensioning piece. The prestressed steel beam tensioning device can achieve tensioning of the prestressed steel beam at the midspan position in the prestressed box girder and can play a role when no tensioning space exists at the girder end, the tensioning condition is limited and the construction period is short.
本发明提供一种预应力箱梁跨中预应力钢束双向张拉连接的装置，包括两相对设置的预应力钢束，还包括，支架，设置在预应力钢束上方；连接组件，连接组件包括两相对设置在支架上的固定轴套，固定轴套与支架滑动连接，固定轴套底端转接有转动拉杆，转动拉杆底端设置有开合件，开合件具有一夹持端和一卡接端；连接锚具，设置在预应力钢束端部，连接锚具通过夹持端和卡接端配合与转动拉杆可拆卸连接；张拉件，张拉件设置在两转动拉杆之间，两转动拉杆通过张拉件沿同轴线相向转动。本发明能够实现在预应力箱梁内部跨中位置实现预应力钢束的张拉，能够在梁端没有张拉空间、张拉条件受限、工期紧张时发挥作用。
