Products Description
Joints are essential reinforcement accessories for aluminum formwork systems, designed to replace traditional through-wall tie rods for concrete shear wall construction. Widely used in residential and commercial building projects, they ensure structural integrity and construction efficiency.
Key Advantages
Waterproof Performance
Permanently embedded in the wall after pouring, eliminating the through-wall holes left by traditional tie rods, thus fundamentally preventing water seepage risks.
01
Precise Wall Thickness Control
The tie length directly controls wall thickness, ensuring uniform stress distribution. The wall verticality and flatness error are controlled within 4mm, minimizing post-pour repair work.
02
High Construction Efficiency
No heavy backform handling required. Fast installation with pins reduces labor intensity, speeds up construction progress, and shortens the project timeline.
03
Wide Compatibility
Available in multiple sizes (200/250/300mm) to match different wall thicknesses. Suitable for complex nodes like T-shaped walls and long walls, with staggered installation preventing formwork expansion.

FAQ
Q: Will the pull-out plates affect the structural strength of the concrete once they are embedded in the wall?
A: No. The pull-out plates are made of steel and provide excellent bond with the concrete. Furthermore, the design accounts for clearance with the wall reinforcement, so they will not compromise the integrity of the concrete. Pull-out plate-type aluminum formwork has been widely used in high-rise residential projects for many years, and its structural safety has been thoroughly verified.
Q: How are the tie plates installed? Is any post-demolition treatment required?
A: Installation is simple and quick: just insert the tie plates into the corresponding holes in the formwork and secure the formwork with pins. After formwork removal, simply use an angle grinder to cut off the exposed portion of the tie plates on the wall surface. There is no need to seal the holes, and the wall can proceed directly to the plastering process.
Q: For which complex structural details can the tie-rod system be used?
A: It offers excellent adaptability and can be used for various complex details such as T-shaped walls, corner walls, elevator shafts, and core walls. By adjusting the spacing and installation method of the tie-rods, it can meet the reinforcement requirements of different structural details.
Q: Is the cost of single-use tie plates higher than that of reusable bolts?
A: The overall cost is actually lower. Although the tie plates are single-use, they eliminate the need for accessories such as bolts, nuts, PVC sleeves, and hole-filling materials. They also save on the high costs of subsequent manual repairs and waterproofing treatments. When calculated overall, a single project can save a significant amount on repair and labor costs.
Q: By how much can the construction efficiency of pull-tab aluminum formwork be improved?
A: Compared to traditional bolt systems, pull-tab installation eliminates the need to handle heavy backing beams, allowing workers to operate more quickly. Overall construction efficiency can be improved by 20%–30%. Combined with standardized construction practices, this enables the achievement of a fast-paced construction target of "one floor every four days."
