The invention discloses a protector for a vertical rubber stanch belt, and the protector comprises a protection panel, wherein a U-shaped is arranged in the middle of the protection panel and used for mounting the vertical rubber stanch belt, the opening end of the U-shaped groove is the upper end, the upper ends of two side panels at two sides of the U-shaped groove are respectively connected with two wing panels, the wing panels are vertical to the side panels, and magnets are arranged on the wing panels. By using the protector, the left or right offset of the vertical rubber stanch belt biased by squeezing of the concrete during construction baiting is avoided, the vertical rubber stanch belt is effectively protected, the anti-seep effect of the vertical rubber stanch belt during the concrete construction can remarkably improved, and the construction quality is improved.
