Pulling force sensor, and pulling force sensor is connected with frame plate and test specimen rebound respectively by the second high-strength bolt.
As preferably, a length of the 730 of described screw rod～820mm, and screw rod uses high strength alloy steel to make.
During this utility model operation, test specimen surrounding pastes concrete strain sheet respectively, measures concrete in tension strain, pulling force
Sensor can directly measure concrete stress, can be connected with computer by Acquisition Instrument and automatically record test data, pass through pulling force
Data and tensile strain data can get concrete in tension stress-strain curve；Described actuator plays ball pivot effect, just
Adjustment centering in test.
After using said structure, what this utility model produced has the beneficial effect that reaction frame described in the utility model is with mixed
Solidifying soil axis pulling experiment device, can accurately measure concrete in tension stress-strain curve, and this utility model has structure letter
Singly, the advantages such as reasonable, cost of manufacture is low are set.

End fixes test specimen rebound 7 respectively, and the test specimen rebound 7 of lower end is connected with frame plate 2 by the first high-strength bolt 8；Upper end
Test specimen rebound 7 and frame plate 2 between pulling force sensor 9 is installed, and pulling force sensor 9 is by the second high-strength bolt 10 points
It is not connected with frame plate 2 and test specimen rebound 7.
As preferably, a length of the 730～820mm of described screw rod 1, and screw rod 1 uses high strength alloy steel to make.
During the operation of this detailed description of the invention, test specimen 6 surrounding pastes concrete strain sheet respectively, and measuring concrete in tension should
Becoming, pulling force sensor 9 can directly measure concrete stress, can be connected with computer by Acquisition Instrument and automatically record test data,
Concrete in tension stress-strain curve is can get by pulling force data and tensile strain data；Described actuator 4 plays ball
Hinge effect, it is simple to the adjustment centering of test.
Using after said structure, what what this detailed description of the invention produced had the beneficial effect that described in this detailed description of the invention is anti-
Power frame concrete axial draws assay device, can accurately measure concrete in tension stress-strain curve, this detailed description of the invention
There is simple in construction, the advantages such as reasonable, cost of manufacture is low are set.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.This
