Outer wrapping type fireproof structure of stay cable
The invention relates to the field of bridge parts, and discloses a stay cable wrapping type fireproof structure. Comprising an embedded cable guide pipe, a stainless steel fireproof pipe, a middle connection cover pipe, a first fireproof sleeve and a second fireproof sleeve, wherein the stainless steel fireproof pipe and the embedded cable guide pipe are coaxially arranged; the middle connection cover pipe is connected between the embedded cable guide pipe and the stainless steel fireproof pipe; the HDPE protective sleeve is arranged in the second fireproof sleeve; the vibration reduction type exhaust mechanism is connected between the embedded cable guide pipe and the first fireproof sleeve; vibration generated by the inhaul cable in daily use drives the corresponding vibration reduction type exhaust mechanism to exhaust air between the inhaul cable and the external hard protection outer layer, so that a state close to vacuum is formed between the inhaul cable and the external hard protection layer, heat conduction of a heat source can be effectively blocked, air is exhausted, and the service life of the inhaul cable is prolonged. Contact between water and the inhaul cable can be effectively reduced, so that the use loss rate of the inhaul cable is reduced, and the service life and stability of the inhaul cable are improved.
本发明涉及桥梁零件领域,公开了一种斜拉索外包式防火结构,包括预埋索导管、与预埋索导管同轴设置的不锈钢防火管、连接在预埋索导管和不锈钢防火管之间的中联罩管、设于预埋索导管内部的第一防火套、设于不锈钢防火管内部的第二防火套、设于第二防火套内部的HDPE护套管以及连接在预埋索导管与第一防火套之间的减振式排气机构;本发明通过拉索在日常使用时产生的振动来驱使相应的减振式排气机构将拉索与外部硬质保护外层之间的空气排出,从而实现拉索与外部硬质保护层之间形成接近真空的状态,可有效的阻隔热源的热传导,并且将空气排出,可以有效的减少水分与拉索接触,从而减少拉索的使用损耗速率,提高拉索的寿命和稳定性。
