Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Join shown in Fig. 1 to Fig. 6, present embodiments provide a kind of experimental rig for Corroded Reinforced Concrete Beam：Main body
Including preventing water leakage galvanized iron sheet 2 (can also be other kinds of antirust iron sheet or preventing water leakage metallic plate), the waterproof of beam box junction
Bed course 4 and the three parts of outsourcing box 3.Preventing water leakage galvanized iron sheet 2 will pass through insulating tape and ring before pouring reinforcement concrete beam 1
Oxygen resin glue fixing seal and carries out encapsulation process with epoxide-resin glue, has then measured iron sheet in the specified location of steel reinforcement cage
Length is bent, allows the iron sheet being folded over to be close to template inwall iron sheet bending, and is closely wound with adhesive tape outer in waiting to stretch out
To prevent from becaming one with reinforced beam 1 on the iron sheet of side, then after test piece maintenance form removal with spanner by iron sheet from
The bending of concrete outer surface is returned, to form a good preventing water leakage confined space.
Outsourcing box is assembled by transparent PVC plate (or armorplate glass) or any transparent material with waterproof effect
Form, the size and thickness of outsourcing box 3 and on-fixed, need to be according to experiment actual conditions depending on, wherein box both sides reserve
Hole hoisting ring 5 and outpacking rubber ring, are easy to the later stage with steel wire rope colligation.Outsourcing box 3 is in bonding with PVC glue or glass
Glue, and apply epoxy resin and make waterproof sealing processing, and waterproof bed course 4 is done in beam box junction, waterproof bed course 4 uses epoxy before this
Resin carrys out smooth interface surface, then seals one layer using glass silica gel, and box finally is bonded in into reinforced concrete using anchoring adhesive
On the preventing water leakage galvanized iron sheet 2 that the native inside of beam 1 is stretched out.Finally by steel wire penetrating reserving hole, box colligation is mixed in reinforcing bar
On solidifying Tu Liang, to play fixation.
In the present embodiment, hoisting ring 5 can be circular, oval or square.
Join shown in Fig. 7, operation principle of the present utility model is：Reinforced beam is treated into corrosion portion envelops stainless steel
Net, sodium chloride solution is then added in the outsourcing box 3 of the present apparatus, while reinforcing bar to be become rusty is connected to direct current by power line
On the anode of voltage-stabilized power supply, stainless (steel) wire is connected on the negative electrode of D.C. regulated power supply by power line.Mixed in reinforcing bar
In solidifying Tu Liang tarnishing processes, the external wrapping concrete caused by steel bar corrosion bulk product expands can be observed by outsourcing box 3
Cracking and crack progressing process, are easy to test data sheet.After reinforcing bar reaches testing program regulation corrosion ratio, can deenergization, will
Sodium chloride solution is discharged, and the present apparatus is removed by reinforced beam bottom.
Experimental rig provided by the utility model for Corroded Reinforced Concrete Beam, have the following technical effect that：
1) each component assembly and connection is simple and reliable, and cost is cheap, can save to Corroded Reinforced Concrete Beam component corrosion
The required expense for building corrosion pond, or the artificial labour cost for manually pouring chloride solution every a few houres toward absorbent materials such as sponges
With.
2) the corrosion situation of institute's acquisition reinforced beam more tallies with the actual situation, while avoids reinforced beam examination
The unwanted corrosion in testing of the reinforcing bar at other positions of part.
3) because outsourcing box uses transparent material, therefore the crack caused by steel bar corrosion can be observed in the whole test period
Development condition, record can be observed with crack observer.
4) because preventing water leakage iron sheet inside beams of concrete by stretching out, so device can solve beam box interface bonding well
Not firm the problem of causing leak.
Described above is only preferred embodiment of the present utility model, is not limited to the utility model, it is noted that
For those skilled in the art, on the premise of the utility model technical principle is not departed from, can also do
Go out some improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
