In the present embodiment, monitoring means is one, and piezoelectric strain gauge 106 is 3, and foil gauge 105 is one, specifically introduces the monitoring principle being applicable to the comprehensive strain monitoring system of builder's jack and method for computing data that the present embodiment provides below:
In construction, when builder's jack 101 is in stress, during by 3 piezoelectric strain gauges 106 that builder's jack 101 is arranged when being subject to space motive power, resistance on its lateral stressed strainometer caused changes, assuming that its initial resistance value is R1, R2, R3, when being subject to horizontal force, the resistance value of generation is R1 ˊ, R2 ˊ, R3 ˊ.Simultaneously, due to vertical load-bearing, larger moment of flexure is created near the position of concrete panel 103 at overhanging type steel beam 102, the entablature of overhanging type steel beam 102 is caused to produce horizontal strain, foil gauge 105 is set herein, stress herein and strain regime can be detected, thus reach the object of monitoring whole builder's jack 101 vertical applied force state.Its initial resistance value of same supposition is R4, and when being subject to vertical acting force, the resistance value of generation is R4 ˊ.Strain is produced by each component, cause the change of each piezoelectric strain gauge 106, foil gauge 105 resistance value, be delivered on statical strain indicator 104 respectively by strainometer wire 108, foil gauge wire 107, then be delivered in PC terminal 109 by signal wire 110 by the data handled by statical strain indicator 104.
There is lower relation of plane in strain stress and resistance variations (△ R/R):
ε＝(△R/R)/GF
Wherein GF (Gage factor) is characterisitic parameter---the sensitivity of foil gauge 105, and by foil gauge 105, manufacturer provides this parameter, is generally 2.0.R be foil gauge 105 when without installation, do not stress, the resistance value measured when room temperature, provides this parameter by the manufacturer of foil gauge 105.
By analyzing, the piezoelectric strain gauge 106 initial resistance value of builder's jack 101 breast piece is R0=1/ (1/R1+1/R2+1/R3), time under stress, R0 ˊ=1/ (1/R1 ˊ+1/R2 ˊ+1/R3 ˊ), the stress difference produced is
ε1＝((R0ˊ-R)/R)/GF
Again by σ 1=κ ε 1, (κ is the sensitivity coefficient of foil gauge 105) can judge the two comprehensive stresses in place.By the monitoring of PC terminal 109 pairs of statical strain indicators 104, the time dependent waveform of each stress can be seen in real time.
1. when σ 1 is constant, on overhanging type steel beam 102, σ 2 increases and exceedes calculated stress: builder's jack 101 load-bearing is excessive, and overhanging type steel beam 102 easily produces larger flexure, causes the unstability of the support body of builder's jack 101;
2. when σ 1 on builder's jack 101 increases suddenly, σ 2 is constant, or builder's jack 101 stress of space symmetr position increases with it suddenly and reduces, then illustrate that the support body of builder's jack 101 has unstability entirety to topple danger;
3. when σ 1, σ 2 increase simultaneously, and monitoring waveform continues to raise up, and illustrates that the support body of builder's jack 101 has larger danger of toppling.
Therefore, the comprehensive strain monitoring system of what the present embodiment provided be applicable to builder's jack can by the lateral stressed state of Real-Time Monitoring builder's jack 101, long term monitoring is done to the space-load state of whole builder's jack 101 and stability, makes construction safer.
