Muscle 2 and aluminium alloy bend up the surface of muscle 4 and all contain layer oxide film.
The inventive method comprises the following steps:
(1) aluminum alloy surface processes.For increasing the cementation between both aluminium alloy muscle and concrete interface, aluminium alloy muscle is entered
Row surface roughness processes, as it is shown in figure 1, before aluminium alloy muscle surface oxidation treatment, by blasting treatment, by abrasive material (gold
Emery etc.) high velocity jet is to aluminum alloy surface so that it is and surface roughness reaches 25～420 μm；Increase aluminium alloy muscle and concrete
Frictional force, do not affect the material property of aluminium alloy muscle simultaneously；Can also be first by aluminium alloy muscle surface machine processing so that it is surface
Become is uneven, carries out surface oxidation treatment the most again, increases mechanical snap power with this.Or aluminium alloy is manufactured band
Rib, needs after completing band rib is carried out oxidation processes, to increase its oxide thickness；Or carry out at wire drawing in aluminum alloy surface
Reason, carries out aluminum alloy surface oxidation after wire drawing processes, increases mechanical snap power with this.Concrete mode of oxidizing, needs to use
The method of anodic oxidation or chemical oxidation carries out surface oxidation treatment to high strength alumin ium alloy, at its Surface Creation layer oxide film, obtains
Aluminium alloy muscle needed for the present invention, to reach the purpose of protection；Can manually thicken the sull of aluminium alloy, strengthen aluminium alloy
The corrosion resistance of goods and wearability.
(2) construction of beam forms.Selecting the suitable beam forms of performance, when preventing casting concrete 5, the pressure of concrete 5 causes
Beam forms occurs more than the deformation that specification allows, and for the beam of differing heights, can install make corresponding beam according to corresponding specification
Template；After beam forms is installed, need to draw center line to check, check each beam forms center correctness.
(3) colligation aluminium alloy muscle.As shown in Fig. 2 (a), Fig. 2 (b) and Fig. 3, use the aluminium alloy muscle that surface has processed,
Its two ends are the most upwards bent up 90 ° of prepared tension aluminium alloy muscle 3, increases mechanical snap power with this.

Fracture.Therefore, when designing the beams of concrete of aluminium alloy muscle arrangement of reinforcement, in particularly making new concrete beam scope in a safe condition
Time, the maximum stress value of tension aluminium alloy muscle 3 should be less than its nominal yield stress value.
Aluminium alloy muscle and regular reinforcement have close intensity, but the elastic modelling quantity of aluminium alloy muscle is about the 1/3 of reinforcing bar, therefore
Under load action, the deformation of aluminium alloy Concrete Beam Reinforced is relatively big, and beam fracture width is relatively big, when using aluminium alloy muscle to carry out beams of concrete arrangement of reinforcement,
In order to reduce fracture width, compare configuration reinforcement time, the ratio of reinforcement of aluminium alloy muscle should properly increase, improve about 2%.
In the present invention, the ratio of reinforcement of longitudinal tensile aluminium alloy muscle is 0.7%～1.0%.

The design discipline of beam is as arrangement of reinforcement foundation.Its Ultimate Strength can carry out arrangement of reinforcement calculating as the following formula:
If when beams of concrete destroys, aluminium alloy is broken, then aluminium alloy beams of concrete spaning middle section ultimate bending moment Mu
Mu=k1k2fcbx2+A′aEaε′a(x-α′a)+Aafu(h0-x))
If beams of concrete causes component damage because of compressive region concrete conquassation, now, then the aluminium alloy beams of concrete spaning middle section limit
Moment MuIt is calculated as follows:
X is concrete compression district height；B is rectangular beam cross-sectional width；fc' for concrete cylindrical comprcssive strength, coagulation can be passed through
Soil cubic compressive strength conversion obtains；k1Ratio for the average compression chord of concrete Yu cylindrical compressive strength；k2For concrete
The pressurized point of resultant force distance to natural axis and the ratio of depth of compressive zone；EaFor aluminium alloy elastic modelling quantity；Aa' for be closed by jewelling
Gold muscle 1 area of section；AaFor tension aluminium alloy muscle 3 area of section；αa' it is that pressurized aluminium alloy muscle 1 center is to compressive region concrete
The distance of outermost edges；h0For beams of concrete effective depth of section；fuFor aluminium alloy ultimate tensile strength；fa *Effective for aluminium alloy
Tensile strength.
Take into full account that under certain particular case after beams of concrete stress characteristic and environmental factors, the arrangement of reinforcement of beams of concrete can all use aluminum
Alloy muscle carries out arrangement of reinforcement, it is possible to use aluminium alloy muscle and the common hybrid reinforcement of FRP muscle, owing to FRP muscle tensile strength is high, but
Shear resistance is weak, therefore with FRP muscle as principal rod, aluminium alloy muscle, as stirrup, carries out hybrid reinforcement.

(1) specific strength of aluminium alloy is high, and intensity and ductility are close with steel, and density is only the 1/3 of steel.With traditional reinforced concrete
Tu Liang compares, and uses aluminium alloy Concrete Beam Reinforced of the present invention can improve bearing capacity in the case of increasing deadweight hardly,
And ensure that beam has good ductility.
(2) the pure aluminum element in aluminium alloy or other elemental metals elements, sudden and violent leakage can react in atmosphere, can enable aluminum alloy to
Surface produces fine and close oxide-film, thus has good corrosion resistance, improves service life and the safety of novel beam, especially
Under erosion environment, its advantage becomes apparent from.
(3) aluminium element content in the earth's crust is only second to oxygen and silicon, occupies the 3rd, is the metallic element that in the earth's crust, content is the abundantest,
And the application of aluminum alloy materials is the most commonplace in daily life, this price enabled aluminum alloy to is can to accept completely in some engineerings
's.
(4) carry out sandblasting oxidation processes on aluminium alloy muscle surface or wire drawing processes, increase the machine between aluminium alloy muscle and concrete
Tool gmatjpdumamics, and then improve the adhesive property between them so that it is can more preferable cooperation.
(5) on the basis of properly increasing the aluminium alloy muscle ratio of reinforcement, concrete fills appropriate polypropylene fibre, plastic-steel fabric
Etc. chopped fiber (steel fibre can not be added, prevent electrochemical reaction), increase substantially the tension of concrete 5, shearing resistance, resist
Folding intensity, significantly increases the rigidity of aluminium alloy muscle arrangement of reinforcement beam, is greatly reduced amount of deflection and the fracture width of aluminium alloy muscle arrangement of reinforcement beam.
During the beams of concrete arrangement of reinforcement of the present invention, the material of use is aluminium alloy, and before arrangement of reinforcement, aluminium alloy is carried out surface process.
