[0014] The present invention provides a steel bar bending resistance detection device for civil engineering, which has the following beneficial effects: (1) The invention uses a hydraulic device to press the steel bars downward so that the steel bars can be tested for bending resistance. When the hydraulic device completes the test and moves upward, the next steel bar to be tested can be placed on the top of the bottom plate through the square hole on the left side of the body. When the hydraulic device moves upward, the hydraulic device drives the rotating column to rotate, and the arc plate moves forward. When the arc plate moves forward, the arc plate can move the steel bars on the top of the bottom plate to the middle part of the bottom plate, which can effectively prevent the position of the steel bars from deviating, thereby causing the hydraulic device to be unable to accurately perform a compression test on the middle part of the steel bars.

When the No. 3 spring contracts, it can be applied to steel bars of different thicknesses, thereby improving the application range of the steel bar bending resistance detection device. When the No. 3 spring moves to the right, the No. 3 spring will drive the bracket to move to the right. When the bracket moves to the right, the bracket will drive the steel bar to move parallel to the right to the bottom of the hydraulic device, thereby preventing the hydraulic device from suddenly starting and causing harm to the human body when it is moved manually.
[0016] (3) In the present invention, when there are bent steel bars, the center of gravity of the bent steel bars is unstable. When the hydraulic device presses the bent steel bars downward, the bent steel bars will move and deviate. When the L-shaped plate moves forward, the L-shaped plate will fix the steel bars front and back to prevent the steel bars from moving. When the rotating rod is reversed, the rotating rod will drive the arc block to move downward. When the arc block moves downward, the arc block will press the steel bars downward, thereby ensuring that the steel bars will not move before detection. When the steel bars pass through the arc frame, the arc frame will limit the steel bars, thereby making it easy to observe whether the steel bars are directly below the hydraulic device.
