Description

Technical Field

[0001] The utility model relates to the technical field of special plugs for concrete pouring, in particular to a special plug structure for clear water concrete pouring. Background Art

[0002] Waterstop bolts are also called split waterstop screws and waterproof screws. They are used to stop water and reinforce building concrete shear walls or civil defense walls as well as to control the formwork. Their greatest performance is the ability to stop water and prevent water.

[0003] The existing water stop bolts include an intermediate screw rod connected to two symmetrical end screw rods, the intermediate screw rod is provided with a water stop plate, and the end screw rods are provided with fastening threads and equipped with fastening nuts. Both ends of the intermediate screw rod are provided with connecting external threads, and one end of the end screw rod is provided with connecting internal threads that match the connecting external threads of the intermediate screw rod. A sealing gasket is provided at the connection between the intermediate screw rod and the end screw rod, which plays the role of fixing the formwork and controlling the thickness of concrete pouring.

[0004] Because the waterstop sheet in the middle acts as an isolation, preventing the infiltrated water from passing through the waterstop screw, it can effectively stop water. However, after the construction is completed, due to the holes on the surface of the formwork, both ends of the waterstop screw will be exposed to the air. The oxygen and water in the surrounding environment will react physically and chemically with the ends of the waterstop screw, causing corrosion at both ends of the screw, ultimately leading to outdoor water seeping into the room, causing wall leakage to occur from time to time, and the sealing effect is poor.
