Tensioning tool for prestressed steel pull rod of building daylighting roof
The invention relates to the technical field of tensioning tools, and provides a tensioning tool for a prestressed steel pull rod of a building daylighting roof.The tensioning tool comprises a fixing base, hydraulic cylinders, clamping plates, an inner circular plate, an outer circular ring and wedge-shaped blocks, the telescopic ends of the two hydraulic cylinders are both connected with tensioning blocks, and guide limiting grooves are formed in the surfaces of the tensioning blocks; the two-way threaded shaft is rotationally connected with the two ends of the guide limiting groove, and the two-way threaded shaft is used for linearly driving the clamping plates; the inner circular plate is coaxially and fixedly connected with one end of the two-way threaded shaft, the outer circular ring is located on the outer side of the inner circular plate, a plurality of grooves are formed in the outer side face of the inner circular plate, a plurality of clamping grooves are formed in the inner side face of the outer circular ring, every two adjacent clamping grooves are tightly connected, one end of each wedge-shaped block is connected with the corresponding groove in a sliding fit mode, and the other end of each wedge-shaped block is inserted into the corresponding clamping groove. And the wedge-shaped block is connected with the bottom surface of the groove through a compression spring. By means of the steel pull rod clamping device, a worker can clearly know whether the steel pull rod is completely clamped or not, and standardization of clamping work is easy to achieve.
本发明涉及张拉工具技术领域，提供了一种建筑采光顶的预应力钢拉杆用张拉工装，包括固定座、液压缸、夹板、内圆板、外圆环和楔形块，两个液压缸的伸缩端上均连接有张拉块，张拉块的表面设置有导向限位槽，双向螺纹轴与导向限位槽的两端转动连接，所述双向螺纹轴用于对夹板进行直线驱动；所述内圆板与双向螺纹轴的一端同轴固定连接，外圆环位于内圆板的外侧，内圆板的外侧面设置有若干个凹槽，外圆环的内侧面设置有若干个卡槽，相邻两个卡槽紧密相连，楔形块的一端与凹槽滑动配合连接，楔形块的另一端插入卡槽中，所述楔形块与凹槽的底面通过压缩弹簧相连接。使用本发明，工作人员能够清楚的知道是否将钢拉杆完全夹紧，夹紧工作易实现标准化。
