Carbon fiber bar anchorage device pre-tightening and tensioning integrated system and pre-tightening and tensioning method
The invention discloses a carbon fiber bar anchorage device pre-tensioning and tensioning integrated system, and belongs to the technical field of pre-stress carbon fiber bars. The system comprises two bases which are parallel to each other; the pre-stressed anchor is arranged between the two mutually parallel bases and is used for connecting the plurality of CFRP ribs in parallel; a first steel block; the two screw rods are parallel to each other; the jack is arranged between the pre-stressed anchor and the first steel block; the second steel block is inserted between the two parallel screw rods and is provided with a first position and a second position; when the second steel block is located at the first position, the jack applies pre-tightening force to the CFRP rib through the second steel block; and when the second steel block is located at the second position, the jack sequentially passes through the first steel block and the screw rod to apply tensioning force to the CFRP rib. The CFRP rib pre-tightening and tensioning device can realize simultaneous pre-tightening and tensioning of a plurality of CFRP ribs, increase the tensioning tonnage and improve the construction efficiency.
本发明公开了一种碳纤维筋锚具预紧张拉一体系统，属于预应力碳纤维筋技术领域。所述系统包括两个相互平行的基座；一预应力锚，设于两个相互平行的基座之间，将多根CFRP筋并联在一起；第一钢块；两个相互平行的螺杆；千斤顶，设于所述预应力锚与所述第一钢块之间；以及第二钢块，插设于两个相互平行的螺杆之间，并具有第一位置和第二位置；当所述第二钢块位于第一位置时，所述千斤顶通过所述第二钢块对所述CFRP筋施加预紧力；当所述第二钢块位于第二位置时，所述千斤顶依次通过所述第一钢块、所述螺杆向所述CFRP筋施加张拉力。本发明可实现多根CFRP筋同时预紧和张拉，增大张拉吨位，提高施工效率。
