Buckle clamping type bridge cable fireproof sleeve and protection system thereof
The invention discloses a buckle clamping type bridge cable fireproof sleeve and a protection system thereof. The buckle clamping type bridge cable fireproof sleeve comprises a first supporting barrel and a hard fireproof barrel. A first butt joint seam is formed in the first supporting cylinder in the axial direction, one edge of the first butt joint seam is bent towards the inner side, and a butt joint part extends in the circumferential direction. A clamping part is formed between the butt joint part and the inner side wall of the first supporting cylinder, and the first butt joint seam is closed after the clamping part is clamped; a first clamping cylinder and a second clamping cylinder axially extend from the two ends of the first supporting cylinder respectively, a bent section is formed between the first clamping cylinder and the first supporting cylinder, the outer diameter of the first clamping cylinder is equal to the inner diameter of the first supporting cylinder, and the inner diameter of the first clamping cylinder is equal to the inner diameter of the first fireproof layer. The inner diameter and the outer diameter of the second clamping cylinder are equal to those of the first supporting cylinder; a second butt joint seam is formed in the hard fireproof cylinder, the hard fireproof cylinder is fixed to the outer side wall of the first supporting cylinder in a bonded mode, and the second butt joint seam and the first butt joint seam are arranged in a staggered mode.
本发明公开了一种卡扣卡接式桥梁缆索防火套及其防护体系，包括第一支撑筒体和硬性防火筒体；第一支撑筒体沿轴向方向形成有第一对接缝，第一对接缝的一条边沿向内侧弯折，并周向延伸有对接部；对接部与第一支撑筒体的内侧壁之间形成有卡接部，卡接部卡接后使得第一对接缝闭合；第一支撑筒体两端分别轴向延伸有第一卡接筒和第二卡接筒，第一卡接筒与第一支撑筒体之间形成弯折段，且第一卡接筒的外径与第一支撑筒体的内径相等，第一卡接筒的内径与第一防火层的内径相等，第二卡接筒的内、外径与第一支撑筒体的内、外径均相等；硬性防火筒体形成有第二对接缝，硬性防火筒体粘合固定在第一支撑筒体的外侧壁上，且第二对接缝与第一对接缝错缝布置。
