Description
Technical field
The utility model is related to a kind of anticorrosion structure of T beams, belongs to bridge structure technical field.
Background technology
Because cost is relatively low when T beams have the advantages that to be easy to largely production, beam body is easy for installation, quantity reaches enough, T
Beam is widely used in construction of road and bridge project.But it is due to the property worked with crackle of armored concrete in itself,
And the effect in dead load and mobile load, defective construction technology, concrete shrinkage, ambient temperature change etc. it is unfavorable because
Under element effect so that crack progressing aggravates.Moisture and salinity in outside air will be in the cracks of easier entrance T beams
Portion, is contacted with the reinforcing bar of the inside, causes iron ion and the oxygen and moisture of intrusion in the destruction of rebar surface oxide-film, reinforcing bar
Generation corrosion is reacted, and reinforcing bar is produced corrosion failure.Especially in coastal area, air humidity and salt content are larger, steel bar corrosion
It is even more serious, the serious curtailment service life of T beams.And some existing anticorrosive measures, for example, being carried out to concrete surface
Handle, increase thickness of concrete cover, improve concrete performance, in measures such as rebar surface increase anticorrosive coats, can be one
Determine to slow down in degree the extent of corrosion of reinforcing bar, but these measures can not all form permanently effective protection to reinforcing bar.
The content of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art and problem that there is provided a kind of T beams
Anticorrosion structure.The utility model mainly includes T beams, activated carbon fiber cloth, reference electrode and potentiostat；Activated carbon fiber cloth
Including tack coat and conductive layer；Reference electrode sets insulation, and it is arranged on beam-ends, is not contacted with reinforcing bar；Will be each in T beams with wire
Root bar parallel gets up, and the negative pole of the power supply in one end and potentiostat of reinforcing bar is connected, the other end and activated carbon fiber cloth
On conductive layer connection, the positive pole connection of the power supply in the conductive layer and potentiostat of the other end of activated carbon fiber cloth, reference
Electrode is connected on the reference electrode binding post in potentiostat.In the structure, the negative pole phase of reinforcing bar and potentiostat in T beams
Even, it is used as protected negative electrode.Power supply, carbon cloth conductive layer, reinforcing bar in potentiostat connect to form closure by wire
Conductive layer on loop, activated carbon fiber cloth produces electronics, electronics is in additional power source as impressed current anode generation electrochemical reaction
Energy of position effect under, flow to reinforcing bar, the galvanic circle make reinforcing bar produce cathodic polarization, enhance to steel bar corrosion in T beams
Suppress, eliminate influence of the corrosion to T beam service lifes.
The conductive layer of activated carbon fiber cloth in the utility model has that electrochemicaUy inert, anode polarization rate be low, loss is few.
The utility model can improve steel bar anti-corrosion ability in T beams, while carbon cloth can also play the work of reinforcing to T beams
With greatly improving the service life of T beams, cost is relatively low, easy to install.

Include：T beams 1, activated carbon fiber cloth 11, reference electrode 10 and potentiostat 12；The top of T beams 1 has poured pave-load layer 13, pave-load layer 13
There is the surface layer 14 of road top.Activated carbon fiber cloth 11 includes tack coat 2 and conductive layer 3；Reference electrode 10 sets insulation, and it is pacified
Mounted in the end of T beams 1, do not contacted with reinforcing bar 4；Each reinforcing bar 4 in T beams 1 is together in parallel with wire, by one end of reinforcing bar 4 and perseverance
The negative terminal 9 of power supply 8 in potentiometer 12 is connected, and the other end is connected with the conductive layer 3 on activated carbon fiber cloth 11, activity
The conductive layer 3 of the other end of carbon cloth 11 is connected with the positive terminal 5 of the power supply 8 in potentiostat 12, reference electrode 10
It is connected on the reference electrode binding post 6 in potentiostat 12.Null electrode binding post 7 is connected with the earth with wire.It is described
Reference electrode 10 purpose be monitored and controlled by the protection potential of protection reinforcing bar 4, the electric potential signal of reinforcing bar 4 is fed to perseverance
Potentiometer 12, automatically to adjust the output current of the power supply 8 in potentiostat 12, so as to reach regulation to defined protection
