Description

一种便于耐久性病害检测的透明拉索
技术领域
本实用新型涉及土木工程及桥梁领域,具体涉及一种便于耐久性病害检测的透明拉索。
背景技术
拉索作为大跨度桥梁(斜拉桥、吊杆拱桥等)的主要的承重构件,在长达几十年使用期内,环境侵蚀、材料老化和荷载的长期效应、疲劳效应与突变效应等灾害因素的耦合作用下,将不可避免地导致结构和***的损伤累积和抗力衰减,从而抵抗自然灾害、甚至正常荷载作用的能力下降,极端情况下引发灾难性的突发事故。拉索钢丝束耐久性病害状况对大跨度桥梁的使用寿命、稳定性和安全性评估具有重要参考意义,为此,我们实用新型了一种便于耐久性病害检测的透明拉索。透明拉索分为全透明拉索和部分透明拉索两类,采用固化高分子层在拉索全长范围内或者部分区域钢丝束表面形成透明拉索护套,不仅隔绝了护套内钢丝束与外界大气流动,而且满足拉索护套力学性能和耐久性要求,与钢丝束之间能够滑移。透明拉索护套既隔绝了空气流动,使透明护套内钢丝束不易锈蚀,又可以通过透明护套观察和评估拉索钢丝束的锈蚀、断丝等耐久性病害情况,解决了拉索的耐久性病害检测问题。
实用新型内容
本实用新型的目的在于提供一种便于耐久性病害检测的透明拉索,能够直观检测拉索耐久性病害的情况。
本实用新型所采用的技术如下:一种便于耐久性病害检测的透明拉索,包括拉索,其特点是,所述的拉索的全长范围内或者部分区域内的钢丝束外层覆有一定厚度的透明高分子材料涂层,从而形成全透明和部分区域透明的拉索护套,该拉索护套能够满足拉索护套力学性能和耐久性,拉索护套能够隔绝外界空气,拉索护套与钢丝束间能够滑移。
本实用新型的透明拉索材料成本低,制备过程较为简单,易于批量生产,并具有直接观察到钢丝束锈蚀情况的优点。过透明固化涂层能直观地观察拉索全长范围内或部分区域内钢丝束腐蚀、断裂等耐久性病害情况。
附图说明
使透明护套内钢丝束不易锈蚀,拉索护套在拉索全长范围或部分区域透明,通过透明固化涂层能直观地观察拉索全长范围内或部分区域内钢丝束腐蚀、断裂等耐久性病害情况。
附图说明
图1为部分区域透明的拉索护套结构示意图;
图2为全透明的拉索护套结构示意图。
具体实施方式
下面根据说明书附图举例对本实用新型做进一步说明:
实施例1
一种便于耐久性病害检测的透明拉索,包括拉索1,其特点是,在所述的拉索的全长范围内或者部分区域内的钢丝束外层覆有一定厚度的透明高分子材料涂层,从而形成全透明和部分区域透明的拉索护套2,该拉索护套2能够满足拉索护套力学性能和耐久性,拉索护套2能够隔绝外界空气,拉索护套2与钢丝束间能够滑移。所述的高分子材料为二甲基硅氧烷高分子。
实施例2
一种便于耐久性病害检测的透明拉索制作方法,如下:
步骤一:将二甲基硅氧烷高分子材料和固化剂以质量比10∶1混合,使用磁力搅拌机在一定转速下均匀搅拌;将得到后的液体放入真空干燥箱中,循环抽真空及放气,除去液体中的气泡;
步骤二:将上述得到的二甲基硅氧烷高分子材料溶液注入全部钢丝束或部分区域钢丝束表面,其中部分透明拉索要求透明区域的高分子材料溶液与非透明区域的聚乙烯护套同时浇筑,然后将其放入烘箱中固化,最后得到的二甲基硅氧烷高分子材料涂覆的透明拉索。
经固化形成满足拉索护套力学性能和耐久性的透明二甲基硅氧烷高分子材料涂层,不但能够隔绝钢丝束与外界空气的接触,而且形成的透明拉索护套可以直接观察到钢丝束的耐久性病害情况。
