Стяжные и водоупорные шпильки

Пятисекционная водоупорная шпилька

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.

Расшифровка марок стали

Марка	Примечание
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.
