Abstract
The utility model is a kind of prestressing tendon for building, including plastic sheath, center is equipped with center steel strand wires in plastic sheath, the outer surface of center steel strand wires is equipped with copper coating, anti-corrosion oil layer is equipped between plastic sheath and copper coating, copper coating outer surface is twisted several copper stranded conductors, copper stranded conductor circumference uniform distribution is in copper coating outer surface, it is twisted on the outside of copper stranded conductor to have several steel strand wires, steel strand wires circumference uniform distribution is on the outside of copper stranded conductor, twisted on the outside of steel strand wires to have several steel-cored aluminium strands, steel-cored aluminium strand circumference uniform distribution is on the outside of steel strand wires.The utility model makes prestressing tendon have good antiseptic property by the way that anti-corrosion oil layer is arranged, service life increases, copper stranded conductor, steel strand wires and steel-cored aluminium strand use make steel wire bundle have stronger tensile strength simultaneously, copper coating is arranged in last center steel strand wires, the friction between center steel strand wires and outer layer steel wire can be reduced, steel strand wires are broken caused by avoiding because of friction.
Description
Technical field
The utility model relates to prestress wire technical field more particularly to a kind of prestressing tendons for building.
Background technique
Prestress wire is one of important materials of prestressed structure, and corrosion resistance directly affects construction quality.
" bridge is body, and line makees string " image describe prestress wire played in modern bridge and highway construction it is important
Effect.In the prior art, prestress wire be after being directly twisted by compressor wire as steel strand finished carry out using.But
It is since the prestress wire itself being directly twisted into does not have antiseptic property, which is easily corroded and rusted.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of prestressing tendon for building.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of prestressing tendon for building, including plastic sheath, center is twisted equipped with central steel in the plastic sheath
The outer surface of line, the center steel strand wires is equipped with copper coating, and anti-corrosion oil layer, institute are equipped between the plastic sheath and copper coating
Stating copper coating outer surface and being twisted has several copper stranded conductors, and the copper stranded conductor circumference uniform distribution is in outside copper coating outer surface, the copper stranded conductor
Side is twisted several steel strand wires, and the steel strand wires circumference uniform distribution is twisted on the outside of the steel strand wires to have several steel on the outside of copper stranded conductor
Core aluminum stranded wire, the steel-cored aluminium strand circumference uniform distribution is on the outside of steel strand wires.
Particularly, minimum 7 of the steel strand wires.
Particularly, the steel-cored aluminium strand quantity is 7~9.
The beneficial effects of the utility model are: the utility model makes prestressing tendon by the way that anti-corrosion oil layer is arranged
With good antiseptic property, service life increases, while copper stranded conductor, steel strand wires and steel-cored aluminium strand use so that steel strand wires
Beam has stronger tensile strength, and last center steel strand wires are arranged copper coating, can reduce center steel strand wires and outer layer steel wire
Between friction, avoid because friction caused by steel strand wires be broken.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- plastic sheath；The center 2- steel strand wires；3- copper coating；4- anti-corrosion oil layer；5- copper stranded conductor；6- steel strand wires；
7- steel-cored aluminium strand；
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, a kind of prestressing tendon for building, including plastic sheath 1, center in the plastic sheath 1
Equipped with center steel strand wires 2, the outer surface of the center steel strand wires 2 is equipped with copper coating 3, between the plastic sheath 1 and copper coating 3
Equipped with anti-corrosion oil layer 4,3 outer surface of copper coating is twisted several copper stranded conductors 5, and 5 circumference uniform distribution of copper stranded conductor is plated in copper
3 outer surface of layer, being twisted on the outside of the copper stranded conductor 5 has several steel strand wires 6,6 circumference uniform distribution of steel strand wires in 5 outside of copper stranded conductor,
Being twisted on the outside of the steel strand wires 6 has several steel-cored aluminium strands 7, and 7 circumference uniform distribution of steel-cored aluminium strand is in 6 outside of steel strand wires.
Particularly, the steel strand wires 6 minimum 7.
Particularly, 7 quantity of steel-cored aluminium strand is 7~9.
At center, copper coating 3 is arranged in 2 outer surface of steel strand wires, can reduce rubbing between center steel strand wires 2 and other twisted wires
It wipes, twisted wire is broken caused by avoiding because of friction, it is additionally provided with several steel strand wires 6, copper stranded conductor 5 and steel-cored aluminium strand 7 outside copper coating 3,
The twisted wire density of unit cross-sectional area is bigger at this time, to improve the intensity of steel wire bundle, uniformly smears in twisted wire outer surface
Anti-corrosion oil layer 4 make steel wire bundle have good antiseptic property, the setting of last plastic sheath 1 is so that prestress steel twist
Harness can be embedded in direct tensioning in component, do not have to default bellows, construct more convenient.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
