Problems solved by technology

This structure not only has higher requirements on the spraying process, but also is easy to fall off, resulting in poor fireproof effect and high manufacturing cost
[0005] The Chinese patent with the publication number CN202347440U discloses a steel wire cable for large-span buildings. The scheme adopts a plastic sheath on the steel wire bundle, and a zinc layer is set between the surface of the steel wire bundle and the plastic sheath, and the zinc layer is coated with an anti-corrosion coating. layer, the zinc layer painting process of this scheme is more complicated and the material cost is higher
[0006] At present, the common disadvantage of the above-mentioned prior art is that the cable fire prevention manufacturing process is relatively complicated and the cost is high

Abstract

A fireproof inhaul cable comprises an inhaul cable body (1), an inner lining pipe (2), a fireproof layer (3) and an outer lining pipe (4). The fireproof inhaul cable is characterized in that the innerlining pipe (2) is nested outside the inhaul cable body (1), the outer lining pipe (4) is nested outside the inner lining pipe (2), and the fireproof layer (3) is arranged between the inner lining pipe (2) and the outer lining pipe (4). The fireproof layer (3) is made of one of a filled-type fireproof material (3a), a bond fireproof filler (3b) or fireproof coating (3c). The invention further provides a manufacturing method of the fireproof inhaul cable. According to the fireproof inhaul cable, a fireproof structure is additionally arranged and the fireproof function is added on the basis that the original functions of the inhaul cable are not changed, the fireproof inhaul cable is independent of an original inhaul cable structure, the lining pipes are easy to replace, the fireproof structure and the fireproof function are safe and reliable, a multi-layer protective structure is formed, the strict requirement for the fireproof safety aspect is met, and the manufacturing technologicalmethod is simple, convenient and practical.

Description

technical field [0001] The invention relates to a cable suitable for structures such as bridge engineering and construction engineering, in particular to a fireproof cable. Background technique [0002] With the progress and changes of social development, bridges, buildings and other fields gradually put forward the demand for fire protection function of cables, and the requirements for fire protection function are getting higher and higher. Cables such as steel wire cables, steel strand cables, etc. are generally extruded with high-density polyethylene, and the PE sheath plays a role in anti-corrosion. However, the PE used on the cables currently does not have fire protection. The application in public facilities such as stadiums, theaters, and exhibition halls requires that the cable itself has a fireproof function. [0003] The Chinese patent whose publication number is CN2644470Y discloses a kind of fireproof cable, and this cable is directly provided with fireproof coa...
