Description
Technical field
The utility model relates to concrete reinforcement cohesive force pick-up unit field, especially a kind of digitizing concrete reinforcement cohesive force pick-up unit.
Background technology
Traditional concrete reinforcement cohesive force pick-up unit has the more defect affecting accuracy in detection, one of them is the unreasonable of its drawing instrument structural design, result in and there will be larger error when being pulled out from reinforced concrete structure by reinforcing bar, thus affect test result.In addition, traditional concrete reinforcement cohesive force pick-up unit is difficult to sample accurately to the force-bearing situation in drawing process, thus is difficult to obtain mechanics parameter comparatively accurately.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can obtains accurately thus process the digitizing concrete reinforcement cohesive force pick-up unit of reinforced concrete pull-out test parameter.
The utility model solves the technical scheme that its technical matters adopts: digitizing concrete reinforcement cohesive force pick-up unit, comprise drawing instrument, described drawing instrument is by upper bearing plate, lower bearing plate be connected described upper bearing plate, the screw rod of lower bearing plate is formed, described upper bearing plate is fixedly installed drawing instrument upper connecting rod, the displacement meter fixture also comprising clamping concrete block and the displacement transducer be arranged on described displacement meter fixture, described lower bearing plate plate face is provided with reinforced steel bar perforation, lower bearing plate is provided with pressure transducer, institute's displacement sensors is all communicated with static resistance strainmeter with pressure transducer.
Further, described pressure transducer top is provided with cushion block.
Further, described cushion block is evenly equipped with through hole.
Further, described pressure transducer is punching pressure transducer.
Further, described static resistance strainmeter is communicated with computing machine.
Further, the reinforced steel bar perforation on described lower bearing plate plate face is arranged at the geometric center place in described lower bearing plate plate face.
The beneficial effects of the utility model are: when reality uses, the drawing instrument of the application can provide a stable drawing environment, and displacement transducer and pressure transducer are all communicated with static resistance strainmeter, therefore the displacement in reinforcing bar drawing process and the pressure parameter very first time can be converged to static resistance strainmeter and to go forward side by side row relax by displacement transducer and pressure transducer timely.In addition, the drawing mode of the application is also convenient to keep stable drawing process in drawing process.The utility model is applicable among the detection of concrete reinforcement cohesive force.
Accompanying drawing explanation
Fig. 1 is the structural representation when drawing of the present utility model.
Be labeled as in figure: drawing instrument upper connecting rod 1, pressure transducer 2, displacement transducer 3, static resistance strainmeter 4, displacement meter fixture 5, reinforcing bar 6, screw rod 7, cushion block 8, computing machine 9, lower bearing plate 10, concrete block 11, upper bearing plate 12, reinforced steel bar perforation 13.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Digitizing concrete reinforcement cohesive force pick-up unit as shown in Figure 1, comprise drawing instrument, described drawing instrument is by upper bearing plate 12, lower bearing plate 10 be connected described upper bearing plate 12, the screw rod 7 of lower bearing plate 10 is formed, described upper bearing plate 12 is fixedly installed drawing instrument upper connecting rod 1, the displacement meter fixture 5 also comprising clamping concrete block 11 and the displacement transducer 3 be arranged on described displacement meter fixture 5, described lower bearing plate 10 plate face is provided with reinforced steel bar perforation 13, lower bearing plate 10 is provided with pressure transducer 2, institute's displacement sensors 3 is all communicated with static resistance strainmeter 4 with pressure transducer 2.
As shown in Figure 1, concrete reinforcement structure to be detected is be inserted into concrete block 11 and the reinforcing bar 6 through concrete block 11.When reality detects, need the upper clamp drawing instrument upper connecting rod 1 of universal testing machine, then by the lower end of the lower clamp of universal testing machine clamping reinforcing bar 6, certainly, reinforcing bar 6 lower end is herein through the reinforced steel bar perforation 13 that lower bearing plate 10 plate face is arranged.To be placed on pressure transducer 2 and displacement meter fixture 5 clamps concrete block 11 because concrete block 11 is fixed, displacement transducer 3 is held on the upper end of reinforcing bar 6, and therefore when concrete drawing, concrete block 11 keeps motionless, and reinforcing bar 6 moves down.The pressure parameter produced in this moves is obtained by pressure transducer 2, and the displacement parameter of generation is obtained by displacement transducer 3, and finally converges to static resistance strainmeter 4 place.General, described pressure transducer 2 is preferably punching pressure transducer.In addition, stressed during in order to ensure drawing evenly, the reinforced steel bar perforation 13 on described lower bearing plate 10 plate face can be selected to be arranged at the geometric center place in described lower bearing plate 10 plate face, thus distribution of force when ensureing drawing is more reasonable.
When reality uses, for preventing concrete block 11 surface irregularity being with bar planting, stress is caused to concentrate, can select between concrete block 11 and pressure transducer 2, place cushion block 8 with holes, namely cushion block 8 is set at the top of pressure transducer 2, thus the impact on detection preventing above-mentioned out-of-flatness from causing.Certainly, uniform through hole on cushion block 8 can also be selected, better to the shield effectiveness of concrete block 11 surface irregularity to testing result like this.In order to the parameter obtained above-mentioned static resistance strainmeter 4 processes easily, described static resistance strainmeter 4 can be selected to be communicated with computing machine 9, thus facilitate data handling procedure, simultaneously, also static resistance strainmeter 4 be can control by computing machine 9, thus pressure transducer 2, displacement transducer 3 Real-time Collection power and displacement utilized.
