Stay cable fire retardant device capable of achieving bidirectional expansion when encountering heat and installation method of stay cable fire retardant device
The invention relates to a stay cable fire-retardant device capable of achieving bidirectional expansion when heated and an installation method thereof.The stay cable fire-retardant device comprises a fire-retardant ring and a positioning clamp, the fire-retardant ring is fixedly arranged on the surface of a stay cable body through the positioning clamp, the stay cable body is wrapped by the fire-retardant ring, the fire-retardant ring is heated to expand inwards to tightly hold the stay cable body, and the positioning clamp is fixed to the surface of the stay cable body. And the stay cable body expands outwards to separate the two sides of the fire-retardant ring. A weather-proof fireproof adhesive tape is wound on the stay cable body provided with the fire-retardant ring, and the fire-retardant ring is arranged on the outer side of the fireproof adhesive tape. The fire-retardant ring comprises a fire-retardant ring shell and a fire-retardant core material, and the fire-retardant core material is arranged in the fire-retardant ring shell. The bidirectional expansion type fire-retardant core material is used as a fire-retardant core part, the characteristic that the bidirectional expansion type fire-retardant core material expands when heated is utilized, the cable bodies are tightly held inwards, the cable bodies on the two sides are separated through outward expansion, and therefore fire spreading is prevented.
本发明涉及一种可实现遇热双向膨胀的斜拉索阻火装置及其安装方法，包括阻火圈和定位夹具，所述阻火圈通过所述定位夹具固定设置在斜拉索索体表面，阻火圈包裹斜拉索索体，所述阻火圈受热向内膨胀抱紧斜拉索索体，向外膨胀隔断阻火圈两侧的斜拉索索体。在设置阻火圈的斜拉索索体处缠绕耐候型防火胶带，所述阻火圈再设置在所述防火胶带外侧。阻火圈包括阻火圈外壳、阻火芯材，阻火芯材设置在阻火圈外壳内部。本申请以双向膨胀型阻火芯材作为阻火的核心部件，利用其受热膨胀的特点，向内抱紧索体，向外膨胀隔断两侧的索体，从而阻止火灾蔓延。
