Water‑Stop Tie‑Rod and Accessories

Simple U Stopper

عددی

The simple rubber water‑stopper, also known as the U Stopper, is a component made of soft PVC used for sealing plastic water‑stop tie‑rods. This piece blocks the plastic tie‑rod sleeve, preventing the passage of water and liquids. One U stopper is used to seal both end sides of the tie‑rod connector.

Sharing:

Not using a U Stopper during the water‑proofing process of the tie‑rod passage will, over time, cause water and liquid leakage from this area.

Consumption Rate of Simple U Stopper

For each plastic water‑stop tie‑rod, one U stopper is required to seal both end sides of the tie‑rod connector.

Storage and Maintenance of Simple U Stopper

Conditions: Keep away from cold and frost, heat, and prolonged direct sunlight.
Optimal Temperature: +10°C to +30°C

Physical and Chemical Properties of Simple U Stopper

Physical Properties

Made of hard but flexible plastic, primarily polypropylene (PP).
Designed in an open U shape that fits onto the tie‑rod sleeve with simple pressure.
Very light and compact, causing no obstruction in the space between formworks.
Sufficient strength to withstand the lateral pressure of concrete and vibration during casting.
Mechanically functions to lock the position of the sleeve or cone to prevent their displacement or removal.

Chemical Properties

Resistant to moisture, alkalis in concrete, chlorides, and other aggressive compounds.
Chemically inert when in contact with concrete and metals, ensuring no corrosion or degradation over time.
Resistant to typical site temperatures (up to about 70 °C) and does not deform under the heat generated by concrete curing.
May include UV stabilizing additives for better resistance to sunlight.
Non‑toxic and non‑corrosive, but, like other plastics, is not biodegradable and should be recycled.

After the plastic cone of the tie‑rod is removed from the concrete, the U stopper is pressed into the middle section of the tie‑rod.
