Five-Section Water Stop Tie Rod
The five-section design leaves the water stop plate embedded in the wall while the outer cones and threads are recovered after concreting, eliminating through-hole leak paths. Water stop plates are supplied welded (e.g. 120×120mm sheet or Ø65mm round) in fixed or movable types for D14/D15/D20 rods, with matching PVC cones and rubber seals.

06Material Grades Explained
| Grade | Notes |
|---|---|
| Q235 | Plain carbon steel. Economic option for light and medium formwork loads. Not heat treated. |
| 45# | Medium carbon steel. The standard formwork tie rod grade in China; quenchable to class 8.8. |
| 40Cr | Alloy steel. Higher hardenability and better fatigue performance than 45#; used where repeated reuse matters. |
| Class 10.9 bolt | Quenched and tempered alloy steel bolt used in the climbing cone set. Not electroplated without a documented baking cycle. |
| QT450-10 | Ductile (nodular) iron with 450 MPa tensile and 10% elongation. Used for sleeves and embedded plates where toughness and castability matter. |
| HRB400 | Hot-rolled ribbed bar (threaded steel) to Chinese standard. Used for embedded foot bolts; good bond with concrete. |
Applications
Procurement Guide
- Provide exact wall thickness — wrong length puts the water stop off-center
- One-sided sealing for walls exposed on one side; two-sided for submerged walls
- Order matching PVC/rubber cones — they seal the recess after stripping
- Middle sections are single-use; outer parts are recovered and reused

Technical FAQ
Five-Section Water Stop Tie Rod — Answers for Engineers and Buyers
Only the middle section is lost in the wall; the two outer bars are unscrewed and reused. This cuts consumable cost significantly on large projects while keeping the watertight water-stop plate in place.
