Description

Technical Field

[0001] The utility model relates to the technical field of performance detection, in particular to a device for detecting the anti-bending performance of steel. Background Art

[0002] With the rapid development of the construction industry at home and abroad, the demand for steel for reinforced concrete in construction is showing a rapid growth trend. The quality of steel for reinforced concrete directly affects the quality of buildings. Currently, existing steel on the market needs to be inspected by authoritative qualification departments before use. The steel tests include tensile test, compression test, bending test, flattening test, impact test, drop hammer test, torsion test, winding test, bond strength, welded joint inspection, and welding process evaluation.

[0003] For example, a device for testing the bending resistance of a pipe with the authorization announcement number CN217954148U includes a fixed platform, both sides of the fixed platform are equipped with adjusting screws, the outside of the adjusting screw is equipped with a fixed square column through a threaded connection, the fixed square column penetrates and extends to the upper end of the fixed platform, an electric telescopic rod is installed on one side of the upper end of the fixed square column, a pressure detector is installed on one end of the electric telescopic rod, a clamping block is installed on one end of the pressure detector, a slide is provided on one side of the front end of the fixed platform, a connecting frame is slidably installed inside the slide, and a meter is installed on one side of the upper end of the connecting frame near the clamping block. The applied force is detected by the pressure detector, and the bending degree is recorded and detected by the meter, so that the testing of the bending resistance of the pipe is more convenient and quick.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can facilitate detection to a certain extent, in actual use, the above device has a poor fixing effect on the detected steel. It only uses fixed square columns to limit the steel. When force is applied to the steel, it may cause the steel to slide off the position, thereby affecting the accuracy of the detection data.

[0005] Therefore, in order to solve the above problems, a device for detecting the bending resistance of steel is proposed. Utility Model Content
