The invention relates to architectural engineering channel steel shearing resistance detecting equipment. Two side stand plates are arranged between an instrument base and a head cover, a power rotating shaft transversely penetrates through the tops of the side stand plates, and the contact part of the side stand plates and the power rotating shaft is sleeved with a bearing; an eccentric disc is fixed to the middle position of the power rotating shaft, and the two sides of the eccentric disc are locked by lock discs; the frame blocks are placed on the two corners of the top of a cut block a, a cushion block clamping groove is formed in the middle of the top of the cut bock a, a cushion block is embedded into the cushion block clamping groove, and the cushion block abuts against the eccentric disc. By adopting the technological means that a macro measurer is arranged on the lower portion of one end of the head cover, a probe is arranged on the lower portion of the macro measurer, and the probe is right opposite to the center of the top of a shelf, the purpose that when deformation that one side of the detected channel steel cocks occurs, deformation can be detected by the high-precision macro measurer is achieved.
