Problems solved by technology

The existing protection system mainly protects the anchor head to a certain extent, and the cable body is exposed to the outside, mainly relying on its own HPDE (high-density polyethylene) for corrosion protection, but in fact HPDE is easy to age and its durability is limited, so usually Rust on the anchor head and steel wire corrosion caused by HDPE cracking will easily affect the service life of the cable

Embodiment 1

[0025] Such as figure 1 , figure 2 As shown, the present invention includes a cable body 1 and a cable anchor head 2, the end of the cable body 1 passes through a building structure 3 and is fixedly connected with the cable anchor head 2, and the cable anchor head 2 The part protruding from the building structure 3 is covered with a protective cover 21, the protective cover 21 is fixedly connected with the building structure 3 and covers the cable anchor head 2 inside, the protective cover 21 and the building structure 3 are fixedly connected by screws 4, and of course can also be sealed and fixed by welding. The protective cover 21 is filled with anti-corrosion grease 22, and the cable body 1 and the anchor head 2 of the cable are connected to the The voids between the building structures 3 are filled with a foaming agent 23, the top of the foaming agent 23 is filled with a cement mortar layer 24, the upper part of the cement mortar layer 24 is provided with a steel cover p...

Embodiment 2

[0029] Such as figure 1 , image 3As shown, the difference between the present embodiment and the first embodiment lies in the additional protective layer. The additional protective layer of the present embodiment includes a steel sleeve 12 sleeved on the periphery of the cable body 1, poured into the The mortar layer 14 between the steel casing 12 and the outer surface of the cable body 1, and the fireproof coating 13 coated on the outer surface of the steel casing 12, the pouring mortar layer 14 is applied to the cable body 1 The protection can obtain the expected protective effect and achieve the purpose of protection. Therefore, the thickness of the fireproof coating 13 provided on the outer surface of the steel sleeve 12 can be appropriately reduced compared with Embodiment 1, so as to reduce the overall cost of the cable.

[0030] The remaining features of this embodiment are the same as those of Embodiment 1.

Abstract

The invention discloses a long-acting building guy cable with good protection effect and long service life, comprising a guy cable body (1) and a guy cable anchor head (2). The guy cable body (1) passes through a building structure body (3) and is fixedly connected with the anchor head (2); a protective cover (21) fixedly connected with the building structure body (3) is coated outside the anchor head (2); anti-corrosive grease (22) is filled in the protective cover (21); foaming agent (23) is filled among the guy cable body (1), the anchor head (2) and the building structure body (3); the top of the foaming agent (23) is injected with a cement plaster layer (24); the upper part of the cement mortar layer (24) is provided with a steel cover plate (25) which is closely combined with the building structure (3); an additional protective layer is arranged outside the guy cable body (1), and comprises a flameproof textile (11) wrapped outside the guy cable body (1), a steel sleeve (12) and a flameproof coating (13) or comprises the steel sleeve (12) sleeved outside the guy cable body (1), a mortar layer (14) injected between the outside surfaces of the steel sleeve (12) and the mortar layer (14), and the flameproof coating (13) coated outside the steel sleeve (12).

Description

technical field [0001] The invention relates to a long-term construction cable. Background technique [0002] The cable structure has become an important form of building structure, and its application in the field of construction is becoming more and more extensive. From individual structural components to the entire structural system, from outdoor hanging to the interior of the structure (indoor), the cable structure is often used. And the cable structure plays an important role in the application of the building. The importance of the cable continues to increase. It is closely related to the structure, use, decoration and cost of the building. The cable has gradually become an irreplaceable important component in the building. Due to The importance and irreplaceability of the cables requires that their service life must be the same as that of the building structure (not less than 50 years), so the protection requirements for the cables are getting higher and higher, and t...
