A detachable type of double pull bolt applied to wall water stop

Abstract

The application discloses a detachable opposite-pulling bolt applied to wall water stop, and relates to the technical field of building construction waterproofing. The detachable opposite-pulling bolt solves the problems of high cost and poor waterproofing of the water stop screw in the prior art. The two ends of the inner screw rod are provided with dumbbell-shaped water stop conical blocks, the water stop conical blocks are detachably arranged on the outer screw rod, the outer screw rod is sleeved with a mountain-shaped clamp and a nut, the mountain-shaped clamp is located between the water stop conical blocks and the nut, and the inner screw rod is coaxially and spacedly provided with a plurality of annular grooves. The outer screw rod of the detachable opposite-pulling bolt applied to wall water stop is detachably connected with the water stop conical blocks, the outer screw rod, the mountain-shaped clamp and the nut can be repeatedly used, the cost of consumables is greatly reduced, on-site gas cutting operation is not needed, construction is convenient, formwork damage and safety risks are reduced, cost is reduced and benefit is increased; the dumbbell-shaped water stop conical blocks are matched with the plurality of spaced annular grooves of the inner screw rod, the water penetration path is prolonged, water penetration into the wall is blocked, the waterproofing of the water stop screw is remarkably improved, and leakage hidden dangers are reduced.
