Vertical prestressed steel bar tensioning auxiliary fastening device and using method thereof
The invention discloses a vertical prestressed steel bar tensioning auxiliary fastening device and a using method thereof, and relates to the technical field of prestressed steel bar tensioning. A vertical prestressed steel bar tensioning auxiliary fastening device comprises a fixing base, a driving chain wheel arranged on the fixing base and rotating around the axis of the driving chain wheel, and a driving structure driving the driving chain wheel to rotate. A driven chain wheel is arranged on one side of the driving chain wheel, the driving chain wheel and the driven chain wheel are sleeved with a chain, a sleeve is coaxially and fixedly arranged in an inner hole of the driven chain wheel, and at least one end of an inner cavity of the sleeve is provided with a fastening section with a regular polygon-shaped cross section. By arranging the chain transmission structure composed of the driving chain wheel, the driven chain wheel and the chain, the driving structure can drive the sleeve to rotate through the chain transmission structure so as to fasten the nut to the prestressed steel bar, and the working position of the driving structure can be transferred to the outer portion of the tensioning support so as to fasten the nut to the prestressed steel bar. The operation space of the driving structure is prevented from being limited by the tensioning support, and the nut fastening efficiency is improved.
本申请公开了一种竖向预应力钢棒张拉辅助紧固装置及其使用方法，涉及预应力钢棒张拉技术领域。竖向预应力钢棒张拉辅助紧固装置，包括固定座，设置在固定座上并绕自身轴线转动的主动链轮，驱动主动链轮转动的驱动结构；主动链轮的一侧设置有从动链轮，主动链轮与从动链轮上套设有链条，从动链轮的内孔中同轴固设有套筒，套筒内腔的至少一端具有横截面为正多边形的紧固段。本申请通过设置由主动链轮、从动链轮和链条构成的链传动结构，不仅可使驱动结构通过该链传动结构带动套筒转动，以将螺母紧固在预应力钢棒上，而且可将驱动结构的工作位置转移至张拉支架的外部，防止驱动结构的操作空间受到张拉支架的限制，提高了螺母的紧固效率。
