Steel structure detection device for constructional engineering

The invention relates to the technical field of detection devices, in particular to a steel structure detection device for constructional engineering. A steel structure detection device for constructional engineering comprises a rotating shaft, a rotating drum, an adhesive tape and a triggering piece. The rotating shaft is arranged in the first direction, can rotate around the axis of the rotating shaft and can move in the second direction, and the rotating drum is arranged in the first direction and sleeves the rotating shaft. According to the steel structure detection device for constructional engineering, the rotating shaft, the rotating drum, the adhesive tape and the triggering piece are arranged to be matched, the relative motion state of the rotating drum and the rotating shaft is changed, then the included angle between the first pasting section and the connecting section of the adhesive tape is adjusted, and after the included angle formed between the first pasting section and the connecting section
