Description

The manufacturing approach that contains the fiber prestress rope of high-toughness wear-resistant sleeve
Technical field
The present invention relates to a kind of building structure and use field of compound material, relate in particular to a kind of manufacturing approach that contains the fiber prestress rope of high-toughness wear-resistant sleeve.
Background technology
Prestressing technique is occupied leading position in concrete-bridge and other concrete construction.Common prestressing force drawing process all is to adopt steel strand wires or reinforcing bar as the stretch-draw parts.
Because iron and steel resource is limited, and since the steam engine invention large scale mining about 300 years.Continuing to bring out and, projected life, quality and other performance of building all being had higher requirement along with the progress of the exhaustion of iron and steel resource, science and technology, novel building composite to the improving constantly of environmental requirement.
The traditional construction material that uses has at present satisfied not the demand of modern architecture thing: the expansion needs of newly-built city, road, bridge have increased new soil and infrastructure investment; Certainly will cause traditional construction material to roll up, and traditional construction material is restricted in many-sides such as the energy, mineral products, environmental protection, fund, geographical position, planning.Traditional construction material resource is also exhausting that constantly the new resources of building trade have become the modern architecture problem demanding prompt solution.
In addition, nonmetallic materials have advantages such as not corrosion, good endurance as the concrete parts of putting more energy into.Present concrete simply supported beam, continuous beam, continuous rigid frame, oblique leg rigid-frame structure, V-type supporting construction etc. based on reinforcing bar and steel strand wires, projected life is often about 40 years; And the use nonmetallic materials can meet or exceed 100 years its projected life; This sees that 2.5 times benefit is arranged in economy, resource on using.
Yet further analysis can be found out, sees from point of view of environment protection, strengthens durability and also has huge benefits: average newly-built or rebuild 2.5 times in 100 years for the building in 40 years life-spans, all to impact environment at every turn.And in rebuild 1.5 times, demolish old building, handle the explosion discarded object of old building, be a big threat to Amenities.Along with the quickening of modernization, the cost of handling discarded expense of building and place is increasingly high.
Therefore, the composite based on carbon fiber, high-performance glass fiber, basalt fibre has the trend that replaces steel in the armored concrete.Extensive use at present fibre-reinforced high molecular material (FRP, fiberreinforced polymer) is arranged as the presstressed reinforcing steel of beams of concrete, main muscle, stirrup and near the tie hoop ground tackle and the stress anchorage head etc. in advance.
Through retrieval, do not find a kind of report that contains the fiber prestress rope of high-toughness wear-resistant sleeve as yet.
201010145839.6) and utility model " a kind of distributed intelligent rope " (application number: 201020156231.9) all do not relate to the high-ductility abrasion-proof overcoat invention " distributed intelligent rope and manufacturing approach thereof " that the applicant declared on April 7th, 2010 (application number:.
Summary of the invention
The object of the invention just is to fill up the blank of prior art, and a kind of manufacturing approach that contains the prestress rope of high-ductility abrasion-proof fiber sleeve is provided.
The objective of the invention is to realize like this:
By the muscle material that the macromolecular material cured fiber forms, its mechanical property is influenced by macromolecular material, shows very high creep, slackness.The present invention proposes to adopt prestress rope as the stretch-draw member, after stretch-draw finishes, pours into the macromolecule sizing material with the mode of mud jacking again, solidifies after it is fully soaked into.Characteristics of the present invention are: under operating temperature, glass fibre or basalt fibre do not have creep and relaxation effect, and substantial effect occurs in more than 500 degrees centigrade.Not have parallel glass fiber or basalt fibre that moment of torsion do not have the twist as the prestressed stretch-draw member, there is not the creep effect of macromolecular material in the stretching process, there is not relaxation effect subsequently yet, can guarantee superior long-term mechanical property.Stretch-draw is being cured later, can bring into play the advantage of fiber, can obtain the steadiness that macromolecular material solidifies again.The carbon fiber microstructure belongs to crystal structure, has certain lax and creep properties, but its intensity is high, elastic modelling quantity is big; Mix use with glass or basalt fibre; Not only improve whole modulus, and have the elasticity of the fiber of low modulus concurrently, have stronger shock resistance.Therefore, doing the stretch-draw member with the muscle material after rope rather than the curing, is one of essential characteristic of this invention.
In the stretching process of prestress rope; The surface of prestress rope and bellows contact position have very big extruding force, are 10 with the tension force of restricting, and 000KN calculates; Laterally extruding force is 2000 to 5000KN; And the contact point displacement of rope and bellows is very big, and often 1 to 15cm, force of sliding friction is also very big.In this case, the parallel fibers of non-packed rope tends to continue fracture of wire, reduces its overall intensity.Therefore, the braiding jacket layer of rope becomes the key of using the present invention, and this invention further with wear-resisting high-tenacity fiber overcoat technology, is improved this technology on the prestress rope technical foundation.Adopting high-ductility abrasion-proof fiber overcoat, is another essential characteristic of this invention.

2. in high-ductility abrasion-proof fiber sleeve surface-coated layer of protecting coating;
3. through cutting, batch and packing and cost prestress rope.
The present invention has advantage and good effect:
1, this prestress rope employing high-performance carbon fibre and basalt fibre are compound; Produce the core body of prestress rope; High-ductility abrasion-proof fiber sleeve in appearance braiding one deck softness of core body, wear-resisting wiping, anti-extruding; And on sleeve pipe, apply a kind of protective finish, make it have prestress rope good with the resin affinity, that bonding is strong;
2, this prestress rope from heavy and light, be convenient to transportation, use and easy for installation, corrosion resistance and good endurance;
3, this prestress rope tensile strength is high, and anti-extrusion performance is strong, is the high-strength stressed material of carrying;
4, this prestress rope has economy, efficient, the characteristic that is suitable for, efficiently solves the bottleneck problem in the current building trade;
5, this prestress rope is compared with other prestressed material, and its price has the remarkable economy advantage under the equal strength condition, and cost will hang down about 20%;
6, this prestress rope has than high-bearing capacity and reliable tension performance it owing to introduced high-toughness wear-resistant fibrous material sheath, combines easily with the sensor fibre technology, makes it to have the dual-use function of primary structure member and sensor.
7, this prestress rope has overcome the anti-environmental corrosion of traditional material and shortcoming such as creep-resistant property is relatively poor, durability is obviously bad, and stable more, reliable in stretching process.
In a word, this prestress rope is the stressed material of a kind of high-strength carrying, is applicable to the prestressed stretch-draw of prestressed concrete beam, truss, oblique-pulling truss structure, the main rope and the hoist cable of suspension bridge, the oblique rope of large span stayed-cable bridge.
