The invention discloses a steel plate suturing method for a concrete panel crack. The suturing method comprises the following steps that S1, a plurality of cutting seams are cut out perpendicular to the concrete panel crack at certain intervals through a pavement cutter; S2, epoxy glue is evenly smeared on steel plates; S3, the steel plates are perpendicularly planted into the cutting seams through a clamp to enable the steel plates to be completely embedded into the cutting seams, and gaps between the steel plates and the cutting seams are filled through epoxy glue; and S4, the overflowed epoxy glue is removed, and natural curing is conducted after the surface of a concrete panel is smoothed. In S1, the diameter of the pavement cutter is 50 cm, the thickness of a cutting disc is 3.8 mm, the thickness of the cutting seams is a half of that of the concrete panel, and the intervals between the cutting seams are 50 cm. The technical scheme has the advantages that a steel plate manufacturing process is simple and convenient, a construction process is concise, the construction period is short, and the influence on traffic is small.
