Aluminum-coated suspension bridge main cable
The invention provides an aluminum-coated suspension bridge main cable, which can effectively improve the temperature field distribution condition of the suspension bridge main cable and reduce the damage of the main cable caused by unbalanced stress distribution between cable strands in the main cable, thereby prolonging the service life of the main cable and the suspension bridge. According to the scheme, the aluminum-coated suspension bridge main cable comprises a sheath, cable strands and an aluminum metal heat conduction layer, wherein the sheath wraps the outer layer of the cable strands, and the aluminum metal heat conduction layer wraps the sheath. The cable is characterized in that the main cable sheath fixes and protects the plurality of cable strands, and the aluminum metal heatconduction layer wraps the sheath. The aluminum metal heat conduction layer is wrapped around the main cable sheath, and the temperature is rapidly conducted away in the aluminum metal heat conduction layer by utilizing the strong heat conduction performance of the metal aluminum, so that the temperature field distribution condition of the main cable of the suspension bridge is effectively improved.
本发明提供一种外包铝式悬索桥主缆，本发明能有效地改善悬索桥主缆温度场分布情况，减少由于主缆内部索股间应力分布失衡而导致的主缆损害，从而延长主缆以及悬索桥的使用年限。方案是：一种外包铝式悬索桥主缆，包括：护套、索股、铝金属导热层；所述护套包裹于所述索股外层，所述铝金属导热层包裹于所述护套外。其特征在于：主缆护套固定并保护若干索股，铝金属导热层包裹于护套之外。在主缆护套外包铝金属导热层，利用金属铝较强的导热性能，使温度在铝金属导热层迅速地传导开，有效地改善悬索桥主缆温度场分布情况。
