Background technology
Steel strand wires are widely used in bridge cable, prestressed concrete member, rock as a kind of high-strength prestress material It is critical primary structure member in the engineering structures such as native anchor cable.Steel strand wires are easily affected by the ambient, occur corrosion life Rust, produces loss of prestress, or even is broken, and will jeopardize engineering structure safety when serious, so the stress to steel strand wires makes Long-term monitoring in real time is carried out with state, whether the stress that can grasp steel strand wires by Monitoring Data is safe, plays advance police It is shown as using, it is ensured that using for engineering structure is safe.
Authorization Notice No. is the B of CN 101210983, entitled " optical fiber grating intelligent steel strand and preparation method thereof " invention Patent, the central hair of its steel strand wires, which is used in fiber reinforcement optical fiber composite reinforcing, the fiber reinforcement optical fiber composite reinforcing, is provided with optical fiber Transmission Fibers in grating sensor, composite reinforcing can be drawn from steel strand wires end, then demodulate back wave long letter with optical instrument Number, the purpose of detection steel strand wires stress can be reached.The technology has the following disadvantages:1)Constitute the outer layer of intelligent steel strand Steel wire and central hair(Fiber reinforcement optical fiber composite reinforcing)Between disperse independent, be not bonded to together, when the stretching of steel strand wires stress When, there is Relative sliding between central hair and cover wire, or even central hair running phenomenon occurs; 2)It is relative due to existing Sliding deformation, after tensioning off-load repeatedly, measurement data can not reset, i.e., it is used as a kind of sensor technology, it is impossible to had Criterion is determined, and limits its application in engineering in practice;3)Steel strand wires do not have corrosion-inhibiting coating, still can not effectively solve steel strand wires The problem of rust corrosion, the durability of influence steel strand wires application has been not suitable with the development trend of current engineering structure durability.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of filling for above-mentioned prior art to bond anti-corrosion type intelligence Steel strand wires, make effectively bond between central hair and cover wire, central hair is really realized that harmony stress becomes with cover wire Shape, is not in stripped thread or running phenomenon, it is ensured that monitoring accuracy, and with overcoat, to solve prior art presence Above mentioned problem.
The present invention the used technical scheme that solves the above problems is:
One kind filling bonds anti-corrosion type intelligent steel strand, and the steel strand wires include central hair and the outer layer wound around central hair It is filled with steel wire, the gap between central hair and cover wire on binding material, the periphery of the cover wire and is provided with painting Coating;The central hair is the strip wire rod for including optical fiber and fiber-optic grating sensor.
Filling of the invention a kind of bonds anti-corrosion type intelligent steel strand, along the length direction of strip wire rod be provided with optical fiber and Fiber-optic grating sensor.
A kind of filling of the invention bonds anti-corrosion type intelligent steel strand, and the surface of the central hair is machined with along its length Groove, optical fiber and fiber-optic grating sensor are embedded in groove, and encapsulation sizing material is filled in groove.
A kind of filling of the invention bonds anti-corrosion type intelligent steel strand, and the central hair is hollow tubular structures, optical fiber and light Fiber grating sensor is located in the tube chamber of the hollow tubular structures.
Filling of the invention a kind of bond optical fiber in anti-corrosion type intelligent steel strand, the optical fiber and fiber-optic grating sensor from Draw the end of steel strand wires.
A kind of filling of the invention is bonded fills out in anti-corrosion type intelligent steel strand, the gap between the central hair and cover wire It is that the coat set on binding resin material, the periphery of the cover wire is resin coating layer filled with binding material.
A kind of filling of the invention bonds the material of anti-corrosion type intelligent steel strand, the binding resin material and resin coating layer For metal or epoxy resin or high-density polyethylene resin or polyureas macromolecule.
A kind of filling of the invention bonds anti-corrosion type intelligent steel strand, and the material of the central hair is glass fibre or carbon fiber Strengthen composite reinforcing.
Due to using such scheme, the present invention compared with prior art, the advantage of the invention is that:
(1)Central hair and cover wire are bonded together by the binding resin material of filling, make central hair real with cover wire Harmony stress deformation is realized, is not in stripped thread or running phenomenon;
(2)Due to eliminating Relative sliding deformation, after tensioning off-load repeatedly, measurement data can be with elastic reset, it is possible to achieve Effectively demarcation, solves its application problem in engineering in practice;
(3)Protection is provided because steel strand wires periphery is coated with resin material, the service life of steel strand wires is improved, ensures engineering knot The durability of structure.
