The utility model relates to the technical field of concrete pouring, in particular to a water stop screw.
Background
The water stop screw is usually used for pouring of the basement shear wall, and plays a role in fixing the template and controlling the pouring thickness of concrete. Different with ordinary wall screw rod lies in: a water stop sheet is arranged in the middle of the water stop screw rod; when the formwork is removed, the common wall-penetrating screw rod is integrally pulled out for repeated use, and the middle section of the water-stopping screw rod is left on the wall body after the two ends of the wall are sawn off, so that the water impermeability of the wall body is ensured. The traditional water stop screw is of a one-section structure, generally, the whole screw is a full-tooth screw, and a water stop sheet is welded in the middle of the traditional water stop screw and used for preventing water from passing through a basement wall. The existing screw with the water stop sheet is welded with a steel water stop sheet in the middle of a through-wall screw, so that the welding leakage risk exists, the welding process is time-consuming and labor-consuming, and the cost is high; the two ends of the common water stopping screw are cut after the common water stopping screw is used, so that the common water stopping screw cannot be reused, and the labor amount of the water stopping screw in the using process is greatly increased; the plugging effect of the common water stopping screw rod after use is not ideal enough, thereby influencing the waterproof effect of the water stopping screw rod.

In the engineering use process, the connecting piece (nut or nut) can still be connected with the connecting piece in a screwing mode, the connecting piece is processed by adopting a cold-rolled strip-tightening steel bar technology, the total processing length of the thread rib is reduced under the condition that the service performance is guaranteed, the strength is high, and the cost is saved. The flexible water stop sheet does not need to adopt a welding process, is convenient to install, does not have a gap, and has a good water stop effect. The connecting threads at the two ends can be detached after use, so that the connecting threads can be repeatedly used, and the cost is saved. The utility model has simple and reasonable structural design, convenient installation, use and operation, high integral strength, less material consumption, resource saving and cost reduction, and the screws at the two end parts can be reused.
Furthermore, the flexible water stop sheet is in interference fit with the middle screw rod and clamped into the gap between the adjacent thread ribs. The size of the opening of the flexible water stop sheet is smaller than the diameter of the middle screw rod, and the flexible water stop sheet is in a tightening state around the middle screw rod after being sleeved in the middle screw rod due to certain elasticity, is clamped into a gap between the two threaded ribs, has no gap with the screw rod, is good in sealing performance, and does not have water seepage hidden trouble.
Furthermore, two ends of the middle screw rod are provided with connecting nuts, and the connecting nuts are respectively in threaded connection with the connecting screw rod and the middle screw rod. The middle screw rod and the two end connecting screw rods are respectively connected together through the connecting nuts, and the mounting and the dismounting are convenient.
Furthermore, the inside of coupling nut is provided with spacing step, right the connecting screw with the mounted position of middle screw rod is spacing. Spacing step sets up in coupling nut's inside, revolves soon to the removal degree when both sides connecting screw and middle screw, when supporting spacing step, can't continue to advance, guarantees the steadiness and the accurate nature of connecting.
Further, coupling nut is the terrace with edge type of gradually widening from inner to outer end, and coupling nut's outer end and wall form are inconsistent, fix and spacing the position of stagnant water screw rod, and the distance between two coupling nut's the lateral surface is promptly the thickness of waiting to pour the wall body.
Furthermore, the outer end of the connecting screw rod is provided with a locking nut.
Furthermore, the locking nut adopts a hexagon nut, so that the locking nut is convenient to screw by using tools, and the mounting and dismounting are convenient and labor-saving.
In conclusion, the middle thread is provided with the spaced thread ribs, so that the material consumption is reduced, and the cost is saved; the flexible water stop sheet is arranged and is in interference fit, so that the mounting and the operation are convenient, and the water stop effect is good; adopt syllogic detachable construction, both ends can take off after the practicality finishes, used repeatedly. Therefore, the utility model has simple integral structure design, convenient manufacture and processing, convenient assembly and disassembly and low manufacture cost.
