Durable composite steel strand stay cable resistant to high fatigue stress amplitude
The invention relates to a durable composite steel strand stay cable resistant to high fatigue stress amplitude, and belongs to the technical field of steel strand stay cables. The cable comprises a composite steel strand unit, and the composite steel strand unit is sequentially divided into a fixed end anchoring section, a fixed end pre-buried section, a free section, a tensioning end pre-buried section and a tensioning end anchoring section; Embedded parts are arranged on the fixed end pre-buried section and the tensioning end pre-buried section in a penetrating mode respectively, a fixed end anchoring part is arranged on the fixed end anchoring section, and a tensioning end anchoring part is arranged on the tensioning end anchoring section, so that the composite steel strand unit is anchored to the tensioning end anchoring part and the fixed end anchoring part; the free section is sleeved with a protection unit, one end of the protection unit is connected with the fixed end pre-buried section embedded part, and the other end of the protection unit is connected with the tensioning end embedded section embedded part. The composite steel strands with the carbon fiber bars are adopted, the use working condition of high fatigue stress amplitude is met, the durability of the inhaul cable is improved, and the cable is suitable for the construction operation requirements of single cable penetrating and single tensioning.
本发明涉及一种耐高疲劳应力幅的耐久型复合钢绞线斜拉索，属于钢绞线斜拉索技术领域。包括复合钢绞线单元，所述复合钢绞线单元依次分为固定端锚固段、固定端预埋段、自由段、张拉端预埋段和张拉端锚固段；所述固定端预埋段和张拉端预埋段分别穿设设置预埋件，所述固定端锚固段上设有固定端锚固件，所述张拉端锚固段上设有张拉端锚固件，使得所述复合钢绞线单元锚固于张拉端锚固件和固定端锚固件；所述自由段上套设防护单元，所述防护单元一端与固定端预埋段预埋件连接，另一端与张拉端预埋段预埋件连接。采用具有碳纤维筋棒的复合钢绞线，满足高疲劳应力幅的使用工况，提高拉索耐久性，适用于单根穿索、单根张拉的施工作业要求。
