Description

Technical Field

[0001] This utility model belongs to the field of steel bar detection technology, specifically a sampling fixture for detecting corrosion of engineering steel bars. Background Technology

[0002] The detection of steel reinforcement corrosion in engineering is a field that integrates multiple technologies. By scientifically selecting and applying appropriate combinations of detection methods, combined with rigorous data analysis and engineering judgment, the corrosion status of steel reinforcement in concrete structures can be accurately assessed, providing crucial information for the safe use, maintenance decisions, and life prediction of structures.

[0003] Meanwhile, the publicly disclosed (announcement) number CN220740913U is a rebar detection clamp, including a device body and an adjustment mechanism set inside the device body. The adjustment mechanism includes a rotating component and a sliding component. The rotating component includes an adjustment drive motor and a swing rod. A connecting plate is fixedly connected to the inner wall of the device body. By setting an adjustment block, the adjustment drive motor can be turned on. The rotation of the swing rod drives the slider to slide along the outer wall of the slide groove. The sliding of the slider drives the sliding rod to slide along the inner wall of the connecting plate. The sliding of the sliding rod drives the adjustment block to slide along the outer wall of the limiting groove. The aforementioned rebar inspection clamp has poor adjustability during use because the cross-section of the rebar is circular, sometimes square with rounded corners, and has multiple nominal diameters. It cannot fix rebars of various sizes, cannot meet the needs of staff, and is inconvenient for inspection.

[0004] Therefore, a sampling fixture for detecting corrosion of reinforcing steel bars in engineering is proposed to address the above problems. Utility Model Content

[0029] The working principle and process of a sampling fixture for detecting corrosion of reinforcing steel bars in engineering projects: When workers need to inspect steel bars for rust, they first turn on the drive motor 31. The main bolt 33 installed at the bottom of the drive motor 31 rotates, causing the drive block 32 to move upward in the partition opening 36 of the partition 35 and the limiting post 34. At the same time, it causes the fixing block 208 and the upper clamp body 206 to move upward, placing the steel bar into the lower clamp body 205. To accommodate the length of the steel bar to be inspected, the workers can turn on the workbench motor 6 installed in the base 1. The workbench bolt 7 moves the front slide 5 horizontally, which in turn moves the lower clamp base 201 and the fixing block 208 horizontally. Then, the drive block 32 descends, clamping the steel bar, allowing for inspection. If workers need to clamp steel bars of different nominal diameters, they can turn on the lower clamp motor 202 installed in the lower clamp base 201. The lower clamp bolt 203 will rotate to open the lower clamp body 205, and the upper clamp body 206 will also open through the above steps, so that the steel bars can be clamped.
