The invention relates to the technical field of a building component, in particular to a water stop screw rod. The water stop screw rod comprises a screw rod, three perforated water stop sheets, connecting rods and handles, wherein the three water stop sheets are tightly connected at the two ends and the middle position of the screw rod; the two ends of the screw rod are provided with sleeve heads connected with the screw rod through screw threads; when the sleeve heads are in a state of being connected with the screw threads of the screw rod, the water stop sheets are attached to the sleeve heads; each connecting rod is arranged on the corresponding sleeve head; a foam layer is arranged on the side surface of each sleeve head; and the handle is arranged on each connecting rod. The water stop screw rod has the beneficial effects that the material recovery of the connecting rods and the sleeve heads arranged on the water stop screw rods is simultaneously realized; and the cost is reduced.
