Abstract
The utility model discloses the enhanced composite winding band of the polyester fiber for bridge cable, it includes substrate layer and top layer, the substrate layer of the enhanced composite winding band of polyester fiber includes laminated polyester film, polyester fiber line is enclosed with laminated polyester film, the substrate layer is bonded by adhesive layer and top layer, and top layer is laminated polyester film or polyester fiber non-woven fabric layer.The utility model improves tensile strength by adding polyester fiber line in substrate layer, together with substrate layer is combined to top layer by adhesive layer again, due to being strengthened using polyester fiber line, therefore its tensile strength under the conditions of condition of equivalent thickness is much higher compared with current commercial band, that is on the premise of use demand is met, it can be made thinner than commercially available band, so as to ensure that band has preferable flexibility, and then ensure that band can tightly touch cable surface in winding process, the problem of winding is not tight is overcome, has favorably ensured the corrosion resistance of cable.
Description
Technical field
Character of Cable Force of Cable stayed Bridge protection technology field is the utility model is related to, more particularly to a kind of polyester for bridge cable is fine
Tie up enhanced composite winding band.
Background technology
Outside the cable of cable-stayed bridge is chronically exposed to, easily because corrosion causes pontic unstable, to improve the service life of cable,
Band would generally be wound outside it with fixed cable and anticorrosion, then outer crowded pe sheath further functions as etch-proof
Effect.
Winding band cable protection system has following features：Also be not in COLOR FASTNESS PROBLEM without application colored paint；By taking
Connect mode and spiral winding, winding system smooth surface are carried out to cable-stayed bridge main push-towing rope；To the band that winds by way of heating
Make overlapping part bonding into a closed entirety.Be wrapped in the band outside cable need to have higher tensile strength and
Preferable low temperature flexibility, when otherwise cable produces elastic telescopic because stress changes, band is easily cracked, particularly low
Under the conditions of temperature, it is easier to the situation of Tensile fracture occur, current commercial band is improved using increase band thickness mostly
Its tensile strength, however thickness increase not only can cost increase, and can cause band flexibility be deteriorated, stiffness enhancing, hold
Easily occur winding the problems such as not tight.
Utility model content
The utility model aims to provide the polyester for bridge cable that a kind of tensile strength is high, flexibility is good, winding is tight
Fiber reinforcement type composite winding band.
In order to solve the above-mentioned technical problem, using following technical scheme：
The enhanced composite winding band of polyester fiber for bridge cable, including substrate layer and top layer, the polyester are fine
Tieing up the substrate layer of enhanced composite winding band includes laminated polyester film, and polyester fiber line is enclosed with laminated polyester film, described
Substrate layer is combined with each other by adhesive layer and top layer, and top layer is laminated polyester film or polyester fiber non-woven fabric layer.
The gross thickness of the enhanced composite winding band of polyester fiber is 0.18mm-0.27mm.
The thickness on the top layer is 0.03-0.12mm.
The top layer is polyester fiber non-woven fabric layer, and the polyester fiber non-woven fabric layer is that terylene short fiber passes through with viscose fibre
Mixing shredding, combing networking, hot-roll forming obtain.
The adhesive layer is polyurethane glue-line.
The utility model uses three-decker, and tensile strength is improved by adding polyester fiber line in substrate layer, then will
Together with substrate layer is combined to top layer by adhesive layer, due to being strengthened using polyester fiber line, therefore it is under the conditions of condition of equivalent thickness
Tensile strength it is much higher compared with current commercial band, that is to say, that on the premise of use demand is met, the utility model
It can be made thinner than commercially available band, so as to ensure that band has preferable flexibility, and then ensure the band energy in winding process
It is enough tightly to touch cable surface, the problem of winding is not tight is overcome, has favorably ensured the corrosion resistance of cable.
