High-strength steel strand inhaul cable for photovoltaic flexible prestressed support and tensioning method of high-strength steel strand inhaul cable
The invention discloses a high-strength steel strand inhaul cable for a photovoltaic flexible prestress support and a tensioning method of the high-strength steel strand inhaul cable, and relates to the technical field of prestress tensioning tools. The high-strength steel strand inhaul cable comprises a cable body, the fixed end of the cable body is provided with a fixed end extrusion anchor, and the fixed end extrusion anchor is installed in a fixed end protection cover filled with anti-corrosion grease; the open end of the fixed end protection cover is connected with a fixed end steel base plate; the tensioning end is provided with a tensioning end extrusion anchor, the tensioning end extrusion anchor is arranged in a sealing cylinder filled with anti-corrosion grease, a supporting cylinder and an anti-loosening anchorage device are sequentially arranged in the sealing cylinder from the tensioning end extrusion anchor, the steel strand penetrates through holes in the supporting cylinder and the anti-loosening anchorage device, and a working clamping piece wrapping the steel strand in the anti-loosening anchorage device is of a three-piece type. The outer side of the sealing cylinder is connected with a tensioning end steel base plate; an anti-corrosion grease layer is arranged on the surface of the steel strand; compared with the prior art, the anti-corrosion effect of the whole inhaul cable is improved, the prestress loss of an anchorage device can be better reduced, and the low-stress anchoring performance of the inhaul cable under the complex geographical condition is effectively improved.
本发明公开了一种光伏柔性预应力支架用高强度钢绞线拉索及其张拉方法，涉及预应力张拉工具技术领域，包括索体，该索体的固定端有固定端挤压锚，固定端挤压锚装在灌装有防腐油脂的固定端保护罩内，该固定端保护罩开口端连接有固定端钢垫板；张拉端有张拉端挤压锚，该张拉端挤压锚装在灌装有防腐油脂的密封筒内，在该密封筒内由张拉端挤压锚起依次设有支撑筒和防松锚具，钢绞线从支撑筒和防松锚具中孔洞内穿过，防松锚具内包裹钢绞线的工作夹片为三片式，密封筒外侧连接有张拉端钢垫板；钢绞线表面设有防腐油脂层；与现有技术相比，本申请提高整个拉索的防腐效果且能更好地降低锚具预应力损失，有效提升了复杂的地理条件下拉索的低应力锚固性能。
