Description
Technical field
The utility model belongs to detection device field more particularly to a kind of device of non-destructive testing steel bar corrosion.
Background technique
For armored concrete due to extensive with raw material sources, the advantages that compression strength is high, and volume stability is good, becomes generation
Widest construction material in boundary.But be affected by, reinforcing bar easily corrodes, to be unable to satisfy the resistance to of structure
The requirement of long property, reduces the service life of building.So the detection of Rust of Rebar in Concrete is particularly important.It is mixed at present
In solidifying soil there are mainly two types of the detection techniques of reinforcing bar: first is that damage testing technology, that is, expose corrosion after removing concrete cover
Reinforcing bar, observe the corrosion situation of reinforcing bar, pass through measurement reinforcing bar cross section loss late and mass loss rate or gravimetric analysis etc.
Method, and then the corrosion of reinforcing bar is analyzed, although the technology is very intuitive, accuracy is high, the stability of meeting structural damage, and examines
It is extremely limited to survey range;It is smaller to the damage of component in the detection process or do not damage second is that non-destructive testing technology, it is main
There are physical measure, analytic approach and chemical measure three categories, since non-destructive testing technology is to the protectiveness of structure safety, this
Technology has become the developing direction of monitoring steel bar corrosion.
Utility model content
Purpose of utility model: it the purpose of the utility model is to provide a kind of test is fast, high sensitivity and can be continuously tracked
Non-destructive testing steel bar corrosion device.
Technical solution: the device of the utility model non-destructive testing steel bar corrosion, the cylinder including bottom end opening are filled in cylinder
Intracorporal electric conduction mortar and several detection reinforcing bars in the electric conduction mortar;The inner wall of the cylinder is coated with epoxy resin
Layer, anti-chloride permeability film is equipped at the bottom end opening of cylinder, the top of the detection reinforcing bar is respectively connected with conducting wire, and the conducting wire is logical
The aperture crossed set on cylinder top is pierced by.
Furtherly, the tapping setting sealing ring of cylinder top is sealed.
Preferably, anti-chloride permeability film is circumferentially fixed fastens with the pressing plate on pressing plate, the bottom end of cylinder is offered
Groove.
It further says, one end of conducting wire is connect with detection reinforcing bar, and the other end is connect with reinforcing bar to be measured, which is equipped with
Galvanometer.
Furtherly, epoxy resin layer prevents reinforcing bar and external environment with a thickness of 0.2~2mm, within the scope of this
It directly contacts, protection detection reinforcing bar is not corroded.
The utility model has the advantages that compared with prior art, the advantages of the utility model are as follows: the device is not necessarily to the protection of damaged concrete
Layer can test out the corrosion condition of detected reinforcing bar quickly, with sensitivity, accurately understand reinforcing bar inside armored concrete
Corrosion situation, and feedback can be continuously tracked, there is real-time;The device is simple simultaneously, carries install convenient, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of utility model device;
Fig. 2 is the circumferentially fixed structural schematic diagram in pressing plate of anti-chloride permeability film of the utility model.
Specific embodiment
The technical solution of the utility model is described in further details with reference to the accompanying drawings and embodiments.
As shown in Figure 1, the device of the utility model non-destructive testing steel bar corrosion, the cylinder 1 including bottom end opening, cylinder 1
Inner wall on be coated with the epoxy resin layer 4 of 0.2~2mm thickness, equipped with anti-chloride permeability film 5 at bottom end opening, the anti-chlorine from
Sub- permeable membrane 5 is circumferentially fixed on pressing plate 7, as shown in Fig. 2, correspondingly the bottom end of cylinder 1 offers and fixes with 7 phase of the pressing plate
The groove of connection.Anti- chloride permeability film 5 is easily sealingly fastened in the bottom end of cylinder 1 by pressing plate 7, and more
It changes conveniently.Electric conduction mortar 2 is also filled in cylinder 1, several detection reinforcing bars 3 of setting, the detection reinforcing bar 3 are set in the electric conduction mortar 2
In in cylinder 1, the top of each detection reinforcing bar 3 is connected with conducting wire 6, and the top of cylinder 1 is equipped with aperture so that conducting wire 6 is pierced by, opens
It is sealed at hole equipped with sealing ring, and then is connect with reinforcing bar 8 to be measured, zero resistance galvanometer 9 is additionally provided on conducting wire 6.The device
It is placed in cylinder 1 by will test reinforcing bar 3, and by epoxy resin layer 4 and covering electric conduction mortar 2, can not only effectively prevent
It is corroded, and combination wire 6 and anti-chloride permeability film 5, so that detection reinforcing bar 3 is connected simultaneously with reinforcing bar 8 to be measured
Forming circuit, and then the corrosion condition of reinforcing bar 8 to be measured is effectively detected out.
The cylinder 1 of the utility model can be cylinder or square tube body, and corresponding pressing plate 7 can be round or rectangular.
Working principle: when preparing armored concrete, equally inside it by the device installation of the utility model pair, and incite somebody to action
Zero resistance galvanometer 9 exposes outside, in order to read data.The other end of conducting wire 6 is connected with reinforcing bar 8 to be measured during installation,
Settable multiple detection reinforcing bars 3 in the device of the utility model, the corresponding device can by multiple conducting wires 6 with it is multiple to be measured
Reinforcing bar 8 is connected.Under the protection of cylinder 1, epoxy resin layer 4 and anti-chloride permeability film 5, detection reinforcing bar 3 is in protection shape
State is not corroded, and reinforcing bar to be measured 8 is corroded due to the influence of external environment, to form current difference between the two, and leads to
It crosses anti-chloride permeability film 5 to be formed into a loop, and then according to the data of zero resistance galvanometer 9 you can learn that armored concrete inside steel
The corrosion situation of muscle.
