Prestressed carbon fiber rib tensioning system and tensioning method
The invention discloses a prestressed carbon fiber rib tensioning system and method, and belongs to the field of carbon fiber rib tensioning. The tensioning device comprises a fixed end and a tensioning end, wherein the tensioning end comprises two tensioning screws which are parallel to each other; the first steel plate is fixedly connected with the two tensioning screws; the tensioning end steel block is in sliding connection with the two tensioning screws and used for being connected with the carbon fiber rib when the carbon fiber rib is tensioned, and the tensioning end steel block is configured to at least enable the carbon fiber rib to wind around the periphery of the tensioning end steel block when the carbon fiber rib is connected; and the jack is arranged between the tensioning end steel blocks, and the jack is configured to be capable of applying acting force to the tensioning end steel blocks so that the tensioning end steel blocks can slide on the two tensioning screw rods, and tensioning of the carbon fiber rib is completed. Operation spaces do not need to be reserved at the two ends of the anchorage device, meanwhile, use of matched anchorage devices can be reduced, and slippage between the carbon fiber rib and the clamping piece and slippage between the clamping piece and the anchor cup are avoided.
本发明公开了一种预应力碳纤维筋张拉系统及张拉方法，属于碳纤维筋张拉领域。它包括固定端以及张拉端，所述张拉端包括相互平行的两张拉螺杆；第一钢板，与两张拉螺杆固定连接；张拉端钢块，与两张拉螺杆滑动连接，用于对碳纤维筋进行张拉时连接所述碳纤维筋，所述张拉端钢块被配置为连接所述碳纤维筋时至少能够使所述碳纤维筋绕过所述张拉端钢块的外周；千斤顶，设置于所述张拉端钢块与张拉端钢块之间，所述千斤顶被配置为能够向所述张拉端钢块施加作用力，以使得所述张拉端钢块在两张拉螺杆上滑行，完成对碳纤维筋的张拉。本发明无需再在锚具两端预留操作空间，同时能够减少配套锚具的使用，避免碳纤维筋与夹片、夹片与锚杯易产生滑移。
