Bridge cable of expansion type sealing fireproof composite structure
The invention discloses a bridge cable of an expansion type sealing fireproof composite structure, and belongs to the technical field of fireproof protection of bridge cables, a flexible refractory material and an expansion flame-retardant sealing tape are used as main fireproof layers, and the surface of a cable steel wire bundle sequentially comprises a wire wrapping layer, an anti-corrosion layer, a fireproof layer and a surface protection layer from inside to outside; a synergistic fire-resistant structure is formed by the expansion flame-retardant sealing tape which is formed by superposing the high-strength fire-resistant flexible fiber material, the expansion flame-retardant sealant and the fire-resistant fiber cloth, so that reliable fire prevention of the cable is ensured; pre-dispersion and closed protection treatment are carried out on fireproof, charring, expansion and other components, the expansion flame-retardant sealant is prepared by optimizing the components and utilizing the prior art, the overall thickness of the sealing fireproof composite structure is greatly reduced while the fireproof performance of the bridge cable is guaranteed, construction is convenient, and the service life of the bridge cable is prolonged. And the quality of the cable expansion type sealing fireproof composite structure is obviously improved, and the cable expansion type sealing fireproof composite structure is high in applicability, outstanding in advantages and wider in market prospect.
本发明公开了一种膨胀型密封防火复合结构的桥梁缆索，属于桥梁缆索的防火防护技术领域，本发明以柔性耐火材料和膨胀阻燃密封带作为主要防火层，从缆索钢丝束表面由内到外依次包括缠丝层、防腐层、防火层和表面防护层，采用高强耐火的柔性纤维材料与膨胀阻燃密封胶和耐火纤维布叠加制成的膨胀阻燃密封带形成协同抗火结构，保证缆索可靠防火；本发明对防火、成炭及膨胀等组份采用预分散及封闭保护处理，通过组份优化，利用现有技术制备了膨胀阻燃密封胶，在保证桥梁缆索防火得同时，大幅降低密封防火复合结构的整体厚度，不仅施工便捷，而且缆索膨胀型密封防火复合结构的质量也得到明显提升，本发明适用性强，优势突出，市场前景更加广阔。
