Embodiment 1

[0024] Such as figure 1 As shown, a new Haval-type fireproof cable includes a cable (1), an inner liner (2) and a fireproof material layer (3), and the outer layer of the cable (1) is wrapped with an inner liner (2), The inner liner (2) is detachably connected by two semicircular tubes, and the outer layer of the fireproof material layer (3) is wrapped with an outer liner (4), and the outer liner (4) is detachable by two semicircular tubes The fireproof material layer (3) is formed between the inner lining pipe (2) and the outer lining pipe (4) by pouring. The fireproof material is firmly installed and has high reliability.

[0025] Such as figure 1 As shown, the outer pipe of the inner liner (2) and the inner liner (4) are of Haval structure, with reliable installation and high connection strength.

[0026] The material of the fireproof material layer (3) is one of fireproof cotton, fireproof blanket, fireproof cloth, perlite filler or ceramic fireproof material, and the ma...

Embodiment 2

[0034] Such as image 3 As shown, the embodiment 2 of a kind of Haval type novel fireproof cable of the present invention, the difference between this embodiment and embodiment 1 is that, in this embodiment, the two semicircular pipes of the outer liner (4) adopt the method Lan (41) is connected and installed.

Embodiment 3

[0036] Such as Figure 4 As shown, the embodiment 3 of a kind of Haval type novel fireproof cable of the present invention, the difference between this embodiment and embodiment 1 is that, in this embodiment, the two semicircular pipes of the outer lining pipe (4) are made of steel Belt (42) binding connection installation.

Abstract

The invention discloses a novel Haff fireproof stay cable and manufacturing method thereof. The novel Haff fireproof cable comprises a stay cable, an inner lining pipe and a fireproof material layer, wherein the inner lining pipe adopts a Haff type structure; the inner lining pipe is coated on the stay cable; the fireproof material layer is coated on the inner lining pipe; and the inner lining pipe is formed by the detachable connection of two semicircle pipes. The novel Haff fireproof stay cable disclosed by the invention adopts the detachable fireproof structure, so that based on that the structure and the function of the stay cable are not influenced, under the working condition that the stay cable is normally used, the mounting and the exchanging of the stay cable fireproof structure can be independently performed, and the normal use of the stay cable are not influenced.

Description

technical field [0001] The invention relates to a cable suitable for structures such as bridge engineering and construction engineering, in particular to a Haval type novel fireproof cable and a manufacturing method thereof. 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. Steel wire cables are one of the key stress-bearing components of cable-stayed bridges, so The steel cables also determine the life span of the bridge. For example, Chinese patent CN2644470Y discloses a fireproof cable, which is provided with a fireproof paint layer or a fireproof wrapping tape on the outer surface of the steel cable body. The layer has reached the level of flame-retardant materials in the current relevant regulations. Compared with the conventional PE sheathed cables ...
