Technical Field
[0001] The utility model relates to the technical field of building steel detection, in particular to a steel strength detection device. Background Technique
[0002] Building construction is a project involving multiple stages such as site selection, planning, design, construction, and acceptance. During the process of building construction, various types of steel are required.
[0003] The steel strength detection device is a device used to evaluate the mechanical properties of steel, mainly used to test key indicators such as the tensile strength, yield strength, and elongation rate of steel. These indicators are crucial for ensuring the safety and reliability of steel in building construction applications.
[0004] During the detection process of the existing steel strength detection device for cylindrical steel (such as steel bars), the steel will be continuously bent by the device, and the two ends of the steel will move and warp. Therefore, during the detection process of the steel, the device does not fix the two ends of the steel. Because if the two ends of the steel are fully fixed, it may cause the steel to break during the bending process, thus affecting the normal progress of the detection and endangering the safety of workers. However, if the two ends of the steel are not fixed, the steel may have a large displacement due to a large bending degree and even fall off the device, thus affecting the accuracy and detection efficiency of the detection results. Content of the Utility Model

By having the outer side surface of the clamping roller be an inwardly concave arc surface, it can play a certain limiting role on the steel bar, and further enable the steel to be located in the middle of the clamping roller, thereby reducing the problem of affecting the accuracy of the detection results due to the position deviation of the steel.

A protective plate is connected to the inner layer of the pressure measuring block away from the pressure sensor.
[0007] The beneficial effect of the present utility model is as follows: The outer wall of the steel is attached to the clamping roller inside the fixed frame. Since the outer side surface of the clamping roller is an inwardly concave arc surface, it can play a certain limiting role on the steel bar, so that the steel can be located in the middle of the clamping roller, thereby reducing the problem of affecting the accuracy of the detection result due to the position deviation of the steel.
