Device and method for vertically tensioning prestressed carbon fiber plate
The invention discloses a device and method for vertically tensioning a prestressed carbon fiber plate, and belongs to the technical field of bridge reinforcement. The device comprises a carbon fiber plate; a fixed end base connected to one end of the carbon fiber plate; a tensioning end base which is connected to the other end of the carbon fiber plate and comprises a tensioning assembly used for tensioning the carbon fiber plate; and a power end base which is close to one side of the tensioning end base and is used for providing tension required for tensioning the carbon fiber plate for the tensioning assembly; wherein the central axis of the carbon fiber plate, the central axis of the tensioning assembly and the tension output axis of the power end base are located on the same horizontal plane. According to the device, a tensioning screw mainly bears axial tension in the tensioning process of the carbon fiber plate, bending deformation is small, the tension applied by the jack can be completely transmitted to the carbon fiber plate, and the design value is achieved.
本发明公开了一种竖向张拉预应力碳纤维板的装置及方法，属于桥梁加固技术领域。它包括碳纤维板；连接于碳纤维板其中一端的固定端基座；连接于碳纤维板另外一端的张拉端基座，所述张拉端基座包括用于对碳纤维板进行张拉的张拉组件；靠近张拉端基座的一侧的动力端基座，所述动力端基座用于向张拉组件提供碳纤维板张拉所需的拉力；所述碳纤维板的中心轴线、所述张拉组件的中心轴线、以及动力端基座的拉力输出轴线在同一水平面上。本发明使得碳纤维板张拉过程中张拉螺杆主要承受轴向拉力，弯曲变形较小，千斤顶施加拉力可完整传递至碳纤维板上，达到设计值。
