Ceramic fiber-coated suspension bridge main cable
The invention provides a ceramic fiber-coated suspension bridge main cable, which can effectively improve the temperature field distribution condition of the suspension bridge main cable and reduce the main cable damage 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 thescheme, the ceramic fiber-coated suspension bridge main cable comprises a cable strand sheath, cable strands, the ceramic fibers and a ceramic fiber maintenance sleeve. The cable strand sheath wraps the outer layer of the cable strand, the ceramic fiber wraps the cable strand sheath, and the ceramic fiber maintenance sleeve wraps the outer layer of the ceramic fiber. The cable is characterized inthat the main cable sheath is used for fixing and protecting the plurality of cable strands, and the aluminum layer wraps the sheath. The ceramic fibers have excellent heat insulation performance, andthe cable strand sheath is wrapped by the ceramic fibers, so that the influence of external factors such as illumination on the temperature of the cable strand in the main cable can be effectively isolated. Therefore, the temperature difference between the internal cable strands is reduced.
本发明提供一种外包陶瓷纤维式悬索桥主缆，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：一种外包陶瓷纤维式悬索桥主缆，包括：索股护套、索股、陶瓷纤维、陶瓷纤维护套；所述索股护套包裹于所述索股外层，所述陶瓷纤维包裹于所述索股护套外，所述陶瓷纤维护套包裹于所述陶瓷纤维外层。其特征在于：其主缆护套固定并保护若干索股，铝层包裹于护套之外。陶瓷纤维具有优异的隔热性能，在索股护套外包裹陶瓷纤维，能有效隔绝光照等外部因素对主缆内部索股温度的影响。从而使其内部索股之间的温差减小。
