Technical Field
[0001] This utility model relates to the field of quality testing technology, and more specifically, it relates to a quality testing device for steel reinforcement in building engineering. Background Technology
[0002] A quality testing device for steel reinforcement in construction engineering is an advanced piece of equipment for testing the quality of steel reinforcement in construction projects. It can quickly and accurately test various physical and mechanical properties of steel reinforcement, ensuring that the steel reinforcement used in construction projects meets relevant standards and specifications.
[0003] In existing technologies, firstly, some devices struggle to detect the bending and misalignment of reinforcing bars, failing to accurately measure the degree of misalignment and reducing detection accuracy. Secondly, manual operation and adjustment of some devices significantly increase detection time, reducing overall work efficiency. The lack of precise mechanical adjustment makes it difficult to ensure consistency of test results between different batches or different operators, and they cannot adapt to reinforcing bars of different specifications and shapes, limiting the application range of the devices. Finally, some devices cannot securely fix the reinforcing bars, potentially causing them to move during the detection process, affecting the test results. Insecurely fixed reinforcing bars may also pose operational safety hazards. Utility Model Content

[0032] In this embodiment, the slider 14 slides on the slide rail 13 to ensure that the detection plate 15 moves smoothly. When the detection plate 15 is moved to a suitable position, the upper support cylinder 16 is activated, pushing the top block 17 to rise. The top block 17 contacts the bottom of the detection plate 15 and presses the bottom of the detection plate 15 to fix the detection plate 15.

[0037] When the longitudinal fine-tuning mechanism is in operation, the slider 14 slides on the slide rail 13 to ensure that the detection plate 15 moves smoothly.
