Then the spring chuck of the taper of conjunction, reinforcing bar two ends to be detected wear spring clip through the mounting hole on base and top plate
Cover reinforcing bar two ends to be detected and reinforcing bar is encased in mounting hole together with spring clip set, still set between the base and top plate
There is the electric hydraulic lifting jack of 2~4 synchronous workings, be evenly distributed between the base and top plate, each described electronic
Connect at the top of piston rod of hydraulic jack between top plate provided with independent a pressure sensor and pressure sensor with controller
Connect, prefastened timing, spring clip be enclosed in the mounting hole of frustum shape occur it is relative slide, force spring chuck to draw in and by steel
Muscle, which is held tightly, to be fixed, and then proceedes to promote base and top plate to promote both to occur relative slide and by pressure by electric hydraulic lifting jack
Sensor record steel bar stretching until fracture when pressure and be converted into tensile strength.
Further, offered respectively at the base upper surface and the corresponding position of top plate lower surface lower locating slot and
Upper locating slot, electric hydraulic lifting jack lower end can be plugged into lower locating slot, electric hydraulic lifting jack piston rod part and pressure
Sensor can be plugged into locating slot, realize the quick location and installation of electric hydraulic lifting jack between base and top plate.
Further, a lead, the lead lower end and base spiral shell are additionally provided between the base and top plate
Line is connected, and top plate is passed through on the vertical direction of upper end, dismounting is easily installed, and play guide effect.
Further, air-bubble level is housed on the base, base keeps horizontality during test, reinforcing bar is only erected
Nogata to stretching.
The beneficial effects of the utility model are：
Compared with prior art, the utility model Portable reinforcing steel bar tensile strength detection means, it is simple in construction, be easy to take
Band, can carry out tensile strength detection to reinforcing bar at the construction field (site), prevent from adulterating and bring quality to endanger to engineering.This practicality
In new, the clamping of reinforcing bar is carried out using the mounting hole of frustum and the spring clip set of cooperation, and spring clip is enclosed on mounting hole cunning
The quick fixation that the reinforcing bar locking being through in spring chuck is clamped and realizes reinforcing bar is gradually tightened up when dynamic.Due in bottom plate and top plate
Being provided with is used for lower locating slot and upper locating slot that electric hydraulic lifting jack Fast Installation is positioned, and achievable device is quickly assembled into
Position and dismounting, adapt to the quick detection requirement of job site.
