Description

一种环氧树脂复合钢绞线 Epoxy resin composite steel strand 技术领域Technical field
本发明涉及一种预应力钢绞线，特别是指一种环氧树脂复合钢绞线。  The invention relates to a prestressed steel strand, in particular to an epoxy composite steel strand.
背景技术Background technique
目前，预应力钢绞线的基本结构是由一根芯线和数根边线绞制而成，其通常不具有防腐蚀性能，当使用在桥梁或其它特殊场合时，作为大跨度建筑基体以外的受力材料需完全裸露在大气当中，因此极易被腐蚀生锈，影响使用性能。为了解决前述问题，本案申请人曾设计出一种具有防腐蚀功能的环氧树脂涂层钢绞线，参考中国发明申请号03140214.3'环氧树脂涂层钢绞线及其制造方法'一案，其是在现有钢绞线的外周涂覆一层具有耐腐蚀功能的环氧树脂涂层，这种结构可有效提供钢绞线以耐腐蚀性能，提升使用效果。At present, the basic structure of prestressed steel strands is made of a single core wire and several edge strands. It usually does not have anti-corrosion properties. When used in bridges or other special occasions, it is used as a base of large-span buildings. The material to be stressed needs to be completely exposed to the atmosphere, so it is easily corroded and rusted, which affects the performance. In order to solve the above problems, the applicant of the present application has designed an epoxy resin coated steel strand with anti-corrosion function, referring to the Chinese invention application number 03140214.3 'epoxy coated steel strand and its manufacturing method', It is coated with a layer of epoxy resin coating with corrosion resistance on the outer circumference of the existing steel strand. This structure can effectively provide the steel strand with corrosion resistance and improve the use effect.
然而，由于建筑阶段性受力的不均衡性，钢构或绳索经常处于微量的收缩或拉长状态，久而久之这些材料表面就会不同程度地产生裂纹，由于环氧树脂涂层仅附着在钢绞线的表面，因此产生裂纹的位置很容易被腐蚀氧化，缩短使用寿命，给此类建筑的设计、施工和使用都带来不小的麻烦；另外，在运输过程中，如果产品的表面受到刮擦，也会将表面的环氧树脂涂层刮掉，露出里面的钢绞线，从而容易腐蚀生锈，影响使用效果，因此对运输过程要求较高，运输成本高。However, due to the uneven distribution of the staged forces, the steel structure or rope is often in a slight shrinkage or elongation state. Over time, the surface of these materials will crack to varying degrees, since the epoxy coating is only attached to the steel strand. The surface of the wire, so the location of the crack is easily corroded and oxidized, shortening the service life, which brings great trouble to the design, construction and use of such buildings; in addition, if the surface of the product is scraped during transportation Rubbing will also scrape off the epoxy coating on the surface to expose the steel strand inside, which will easily corrode and rust and affect the use effect. Therefore, the transportation process is required to be high and the transportation cost is high.
鉴于前述分析，本设计人针对现有的钢绞线结构进行研究改进，本案由此产生。In view of the foregoing analysis, the present inventors made research and improvement on the existing steel strand structure, and the present case was produced.

一种环氧树脂复合钢绞线，在线束的外周涂覆环氧树脂涂层，所述带有环氧树脂涂层的线束外部还套设有一弹性套管，且该弹性套管的内径大于涂覆有环氧树脂涂层的线束的外径。An epoxy resin composite steel strand coated with an epoxy resin coating on the outer circumference of the wire bundle, the outer portion of the epoxy resin coated wire bundle is further sleeved with an elastic sleeve, and the inner diameter of the elastic sleeve is larger than The outer diameter of the epoxy coated epoxy wire bundle.
上述弹性套管是使用橡胶成型技术制成。The above elastic sleeve is made using a rubber molding technique.
采用上述方案后，本发明通过在具有环氧树脂涂层的线束外部再套设一套管，具有以下优点：After adopting the above scheme, the present invention has the following advantages by further arranging a sleeve outside the wire bundle coated with epoxy resin:
（1）套管的内径大于线束的外径，可为线束提供伸缩空间，且套管由弹性材质制成，利用其弹性作用具有预应力、后张力设计，即使线束处于收缩或拉长状态，也不会造成套管的破裂，延长使用寿命；(1) The inner diameter of the sleeve is larger than the outer diameter of the wire harness, which can provide a telescopic space for the wire harness, and the sleeve is made of an elastic material, and has a prestressing and post tension design by utilizing its elastic action, even if the wire harness is in a contracted or elongated state, It will not cause the casing to rupture and prolong the service life;
（2）套管在外部起到保护的作用，防止运输过程中对环氧树脂涂层造成划伤，从而可降低运输成本。(2) The casing acts as a protection on the outside to prevent scratching of the epoxy resin coating during transportation, thereby reducing transportation costs.
