Water‑Stop Tie‑Rod and Accessories

عددی

Using tie rods and anchoring equipment in concrete formwork is essential. Without proper bracing of the formwork using tie rods, nuts, washers, and other accessories during concrete pouring, the hydrostatic pressure of the concrete can cause the formwork to collapse, resulting in serious damage to the structure.

Correct Consumption Rate of Double‑Ended Plastic Cone Sleeve

To determine the correct consumption rate of the double‑ended plastic cone sleeve, the number of tie rods (bolts) required for formwork should be considered. Generally, for each square meter of wall, two tie rods are needed. Therefore, for every square meter of wall, you will also require two plastic bolt covers, or double‑ended cone sleeves.

Consumption per 1 m² of wall:

2 tie rods
2 double‑ended plastic cone sleeves

Storage and Maintenance of Double‑Ended Cone Sleeve:

Keep away from cold and frost, excessive heat, and prolonged direct sunlight.
Ideal storage temperature: +10 °C to +30 °C.

Physical and Chemical Specifications of the Double‑Ended Plastic Cone Sleeve

Physical Specifications:

Material: Made from rigid yet semi‑flexible plastic, mainly polypropylene (PP) or high‑density polyethylene (HDPE).
Shape: Slim cylindrical body with flared ends or rims for easy connection to plastic cone pieces.
Length: Depending on wall thickness, usually between 10 cm and 20 cm.
Internal Diameter: Sized to match the tie rod passing through (typically 16 mm or 18 mm), allowing the rod to pass easily without looseness.
Smooth interior surface to prevent friction or tie rod jamming.
Resistant to concrete pressure and vibration from compactors.
Very lightweight, easy to install, and compatible with various types of standard or spring‑type plastic cones.

Chemical Specifications:

Resistant to the alkalinity of concrete, moisture, chlorides, and other aggressive chemical compounds.
Inert in contact with concrete and steel; causes no chemical reaction, corrosion, or decay.
Stable under typical construction site temperatures (about ‑10 °C to +70 °C).
Often contains UV stabilizers and thermal stabilizers for improved resistance during storage or outdoor exposure.
Non‑corrosive, non‑toxic, and structurally neutral within concrete.
Like most polymers, non‑biodegradable in nature but fully recyclable.

How to Use the Double‑Ended Plastic Cone Sleeve

After completing wall reinforcement and installing the formwork on one side of the wall, proceed as follows:

Insert the tie rod (bolt): Insert the bolt from the side where the formwork is already installed.
Install the plastic bolt cover: Place the plastic cover so it acts as a sleeve over the surface of the bolt.
Position the double‑ended cone sleeve: After placing the sleeve, install the formwork on the opposite side of the wall.
Tighten the anchors and washers: Secure the anchors, washers, and nuts on the back of the formwork.
Concrete pouring and formwork removal: After pouring the concrete and removing the formwork, the bolts can be easily taken out.
Remove the cone ends: Use pliers to remove the cone tips from the double‑ended sleeve.
Fill the holes: Fill the remaining holes with cement mortar or grout (preferably a mix of grout and waterproof bonding agent).
