[embodiment]
The structure that the reinforcing bar of the embodiment of the present invention 1 plays rust and the suggestion device of chlorine ion concentration ultimate limit state as shown in Figure 1, comprises string wire 2, shelf 1, tension adjustment screw 3 and tension adjustment nut 4.
In the present embodiment, string wire 2 has been rust test specimens, and string wire 2 is tightened by shelf 1.String wire 2 can adopt high-strength very thin steel wire, and diameter is not more than the spring steel wire of 0.16mm.
Shelf 1 use stainless steel bar shaped plate bending forms, and respectively there is a mounting hole at the two ends of stainless steel bar shaped plate.Pin 8 is through the mounting hole of stainless steel bar shaped plate left end, and the left end of string wire 2 is fixed on the end of pin 8; Tension adjustment screw 3 is through the mounting hole of stainless steel bar shaped plate right-hand member, the right-hand member of string wire 2 is fixed on the inner of tension adjustment screw 3, tension adjustment nut 4 screws in the outer end of tension adjustment screw 3, and rotating tension adjusting nut 4 can be adjusted the flexibility of shelf 1, changes the tension force of string wire 2 simultaneously.Stretch-draw string wire 2 is during to predetermined stress value, then uses clamp nut 5 fixed adjustment nuts 4, and bending stainless steel substrates 1 maintains and stablizes lasting tension string wire.
Selected steel wire string corrosion test section (the each 30mm in optional mid point left and right or definite according to the actual requirements), and the remainder of steel wire string is added and is coated with rust inhibiting primer (red lead, epoxy zinc-rich paint etc.).
Reinforcing bar for exposed reinforcement or employing reinforcing steel method plays rust and criticality chlorine ion concentration research, above-mentioned reinforcing bar can be played to the suggestion device of rust and chlorine ion concentration ultimate limit state, be placed on (as maybe needed in corrosion environment simulation box in the reinforced concrete actual working environment of monitoring) in corrosion environment, when string wire 2 ruptures, when shelf 1 flicks, prompting reinforcing bar plays rust, reaches chlorine ion concentration ultimate limit state.
The present invention is by the string wire disconnected rust event that rises that characterizes tension reinforcement and the chlorine ion concentration state that reaches capacity that becomes rusty, maintaining by stainless steel substrates the target tension that puts on string wire presets by the ultimate tensile strength (UTS) of string wire, and a little less than the latter, generally, the 75-85% that the target stress of bowstring under trystate is its tensile strength.Once string wire corrosion also causes the faint damage in its cross section, there is rust disconnected.The method of the present embodiment not only can be used for studying rust time and a criticality chlorine ion concentration regularity of distribution of different corrosion environment reinforcing bars, also can be used for studying the impact of effect of stress on reinforcing bar corrosion resistance.
The embodiment of the present invention 2 reinforcing bars play rust and the structure of chlorine ion concentration ultimate limit state suggestion device as shown in Figure 2, on the basis of embodiment 1, increased cement paste test block (or concrete test block) 6, the middle part of string wire 2 is imbedded in cement paste test block (or concrete test block) 6.The reinforcing bar that the device of the present embodiment is mainly used in studying reinforcing bar in cement paste or concrete test block plays rust and criticality chlorine ion concentration, in steel wire string corrosion test segment limit, builds small size cement paste or concrete test block (as 60mm × 60mm × 60mm test cube) around string wire.Standard curing cement paste or concrete sample when specifying the length of time, are placed in corrosion environment by arch unit and test block entirety.When string wire generation corrosion, cross section weaken and while disconnecting, arc stainless steel substrates resilience is opened, and significantly points out reinforcing bar to play rust, reaches chlorine ion concentration ultimate limit state.
The embodiment of the present invention 3 reinforcing bars play rust and the structure of chlorine ion concentration ultimate limit state suggestion device as shown in Figure 3, on the basis of embodiment 2, have increased warning circuit, and warning circuit comprises power supply B and pilot lamp L, power supply B and pilot lamp L series connection; The two ends of warning circuit are electrically connected with the two ends of string wire 2 respectively.When cement paste test block (or concrete test block) 6 dense, and the stress of string wire 2 is less, when string wire generation corrosion disconnects, but can not extract out from test block 6 more greatly because of surface corrosion resistance time, arc stainless steel substrates can not open in resilience, now the pilot lamp L of warning circuit extinguishes, and instruction string wire 2 reality disconnect, have reached reinforcing bar and have played rust and chlorine ion concentration ultimate limit state.
The calibrating installation of the embodiment of the present invention 4 string wire stress as shown in Figure 4, stress calibrating installation comprises that one end of spring balance 7, spring balance 7 is fixed on one end of described suggestion device shelf 1, and the other end of spring balance 7 is fixed on the other end of shelf 1 by described test specimen tensioning device; While calibrating the stress of string wire 2, according to the pulling force of the sectional area of string wire 2 and target Stress calculation string wire 2, the value of thrust that adjustment test specimen tensioning device shows spring balance 7 reaches the pulling force of string wire 2, measures the opening value B of shelf 1; Then as shown in Figure 1, the spring balance on shelf 17 is taken off and changes string wire 2, adjust test specimen tensioning device and make shelf 1 reach above-mentioned opening value B, bowstring 2 reaches target stress.
The present invention is above by a string wire disconnected rust event of tension reinforcement and the concentration of chlorion or other harmful ions state that reaches capacity that characterizes that become rusty, the present invention maintains by stainless steel substrates the target tension that puts on string wire and presets by the tensile strength of string wire, and a little less than the latter; Once string wire corrosion also causes the faint damage in its cross section, there is rust disconnected.Analogue means and method not only can be used for studying rust time and a criticality chlorine ion concentration regularity of distribution of different corrosion environment reinforcing bars, also can be used for studying the impact of effect of stress on reinforcing bar corrosion resistance.
