Abstract
The utility model relates to a durable cable body structure, which mainly aims to be applied in a cable stayed bridge, an arch bridge and other large span structures. The model comprises a galvanized steel wire cable body (1), a polyester fiber layer belt (3) winded on the galvanized steel wire cable body and a high density polyethylene sheath (4) wrapped on the polyester fiber layer belt. It is characterized in that the galvanized steel wire cable body (1) and the high density polyethylene sheath (4) is winded by a polyvinyl fluoride film adhesive tape layer (2). The utility model can protect the galvanized steel wire cable body form being invaded by harmful elements like water or gases in case the HDPE sheath of the cable is damaged by accident.
Description
Technical field:
The utility model relates to a kind of novel durable inclined guy cable body structure, is mainly used in cable stayed bridge, arch bridge and other and strides gauge structure greatly and make drag-line.Belong to bridge construction part technical field.
Background technology:
The dragline structure that uses in bridge types such as cable stayed bridge, arch bridge at present, it is at the external high-strength polyester fiber band of one deck, a hdpe layer (HDPE) sheath that is covered the polyester fiber band outside again of twining earlier of galvanized steel rope.This cable body structure, when the unexpected breakage of its outer field HDPE sheath, hazardous substancess such as water, gas can be invaded galvanized steel rope body.The steel wire corrosion that this will cause drag-line causes drag-line to lose efficacy.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can guarantee that hazardous substancess such as water, gas can not be invaded the novel durable dragline structure of galvanized steel rope body when the unexpected breakage of the HDPE of drag-line sheath.
The purpose of this utility model is achieved in that a kind of novel durable dragline structure, comprise galvanized steel rope body, be wrapped in the external polyester fiber belt of galvanized steel rope and be coated on the outer high density polyethylene (HDPE) sheath of polyester fiber belt, it is characterized in that: the external or high density polyethylene (HDPE) sheath of described galvanized steel rope twines one deck polyvinyl fluoride thin film adhesive tape layer outward again.
Polyvinyl fluoride thin film adhesive tape (hereinafter to be referred as PVF) by du pont company in utility model in 1940.This product is the film by the polyvinyl fluoride extrusion molding, and thickness is generally 12.5～50 μ m.The fluorinated film of this 100%PVF content has been avoided defectives such as surface pinholes, crackle fully, and the special performance of PVF film comprises outstanding weatherability, splendid mechanical performance, ductility, and the corrosion of anti-numerous chemicals, solvent and colorant.It directly is wound in the galvanized steel rope body external enwergy, and directly protection is when the HDPE of drag-line sheath accident is damaged, and hazardous substancess such as water, gas can not be invaded galvanized steel rope body, thereby guarantee that steel wire is not by corrosion; Directly protect the high density polyethylene (HDPE) sheath not to be etched and it is wound in high density polyethylene (HDPE) sheath external enwergy, thereby hazardous substancess such as indirect protection water, gas are invaded galvanized steel rope body, thereby guarantee that steel wire is not by corrosion.
Description of drawings:
Fig. 1 is embodiment 1 structural representation of the utility model novel durable dragline structure.
The specific embodiment:
Embodiment 1: referring to Fig. 1, the present embodiment novel durable dragline structure, it is to twine one deck polyvinyl fluoride adhesive tape layer (PVF film) 2 outside galvanized steel rope body 1 earlier, twine the high-strength polyester fiber band 3 of one deck again, outside polyester fiber band 3, twine a hdpe layer (HDPE) sheath 4 again.
Embodiment 2: the difference of present embodiment and embodiment 1 is: polyvinyl fluoride adhesive tape layer (PVF film) 2 directly is wound in outside high density polyethylene (HDPE) (HDPE) sheath 4.All the other are all with embodiment 1.
Claims (1)
1, a kind of novel durable dragline structure, comprise galvanized steel rope body (1), be wrapped in the external polyester fiber belt (3) of galvanized steel rope and be coated on the outer high density polyethylene (HDPE) sheath (4) of polyester fiber belt, it is characterized in that: twine one deck polyvinyl fluoride thin film adhesive tape layer (2) outside described galvanized steel rope body (1) or outside the high density polyethylene (HDPE) sheath (4) again.
