Description
Technical field
The utility model belongs to anchorage technology field, more particularly to a kind of composite anchorage of FRP presstressed reinforcing steels.
Background technology
The development of overwood engineering discipline is largely dependent upon the new diseases haveing excellent performance and development.It is such as right
In traditional reinforcing bar, the new material that a kind of intensity is high, light-weight and durability is good should be found to substitute adding for existing structure
Gu, repair and transformation, should be the excellent properties such as to significantly improve with structural bearing capacity after specific strength height, quick construction, construction
Material is replaced.Therefore, the excellent composite material of utility, which is updated traditional material, is transformed into century wood engineering neck
The great research topic of domain sustainable development.
Bond type anchorage includes resin bushing anchorage and resin-encapsulated anchorage.Sleeve anchorage be inner surface it is threaded or warp
Resin sand or cement is perfused in the metal of machining deformation or nonmetallic sleeve and is made.This kind of form anchorage is the disadvantage is that anchorage is long
Degree is big, impact resistance is poor, creep and anti humid heat endurance issues.Experimental study and finite element analysis show, anchoring resin
The rigidity of filler becomes larger from anchoring front end to rear end, can get satisfied anchoring effect.Based on this, it is rigid that Japan develops change
Resin-encapsulated anchorage is spent, static(al) and the fine European Company of Fatigue Anchorage Property will be bonded for analysing bridge intermediate plate similar to anchorage
Intermediate plate with fat formula anchorage in conjunction with and the anchorage developed, such anchorage can be used for the anchoring of more FRP tendons.
FRP, fibre-reinforced plastics are English（Fiber Reinforced Plastics ）Abbreviation, it is existing
CFRP, GFRP, AFRP, BFRP etc..That fiberglass refers in Chinese is exactly GFRP.FRP composite materials are by fibrous material and matrix
The high-performance proximate matter material that material is formed after mixing according to a certain percentage.Wherein GFRP has according to used resin variety difference
The types such as organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics.General FRP has light and hard, non-conductive, high mechanical strength,
Recycle few, the characteristics such as corrosion-resistant.
FRP is with its excellent mechanical property and adapts to modern project structure to the need developed across, towering, heavily loaded, lightweight greatly
It asks, is just applied in science of bridge building, all kinds of civil buildings, ocean engineering, underground engineering more and more widely, by structure
Engineering circles extensive concern.
The tensile strength of FRP is high, and the tensile strength of FRP is obviously higher than reinforcing bar, not with high tensile steel wire tensile strength difference
More, usually 2 times of reinforcing bar are even up to 10 times；Coefficient of thermal expansion is close with concrete, in this way when environment temperature changes
When, FRP and concrete co-ordination not will produce big temperature stress between the two；Compared with steel, most of FRP products
Elasticity modulus is small；It is polymerized by matrix because FRP is fiber, intensity is determined by matrix between fiber（Intensity is generally weaker than fibre
Dimension）, so weaker perpendicular to machine direction intensity；FRP material is anticorrosive, anti-fatigue performance is good, can acid, alkali, villaumite and
It is used for a long time in moist environment, thus the service life of structure can be improved, this is that structural material hardly matches.
FRP tendons tensile strength is high, is well suited for being used for prestressed concrete, but lateral shear resistance not as good as steel it is good.And it is same
When working tension and the composite stress state of transverse pressure be but present in the anchor tool system of anchoring prestress muscle.When principal stress is super
When crossing the critical value of muscle and being broken, the tensile strength of muscle will be made to be not in full use.Bond type anchorage and strand tapered anchorage
There is the limitation of its own.Bond type anchorage due to needing larger anchorage length, and strand tapered anchorage be in for a long time it is larger
Make the FRP tendons sensitive to damage that fatigue rupture easily occur since the rigidity of intermediate plate small end is larger under Fatigue Stress Amplitude state, because
This, needs to design novel anchorage.
