Assembly type steel plate box inter-width rapid assembly and anti-shearing connector water stop device

The invention discloses an assembly type steel plate box inter-width rapid assembly and anti-shearing joint water stop device which comprises two limiting protruding edges arranged oppositely, the groove wall of a socket groove of a steel plate box forms the limiting protruding edges, the limiting protruding edges are arranged in the length direction of the socket groove, and a containing groove is defined by the two limiting protruding edges and the groove wall; one side of the elastic sealing strip is embedded in the accommodating groove, and the other side of the elastic sealing strip extends to the outer side of the accommodating groove; and the water swelling strip is installed at the groove bottom and connected to the outer sides of the limiting convex edges, and after the inserting tenon of the steel plate box is inserted into the socket groove, the inserting tenon abuts against the two limiting convex edges so that the other side of the elastic sealing strip can be extruded into the containing groove.
