Precast wall connection wire loop boxes, also known as wire loop boxes or connection loop boxes, provide a dependable solution for structural joints in precast concrete construction. They simplify installation, reduce the need for formwork, and enhance joint stability. The flexible loops are released on-site with tear-off tape, making them highly efficient for contractors. With CE and ISO 9001 certification, they deliver consistent performance and ensure long-term structural safety.
Also called wire loop box or connection loop box, this product is designed as a structural connection system for precast elements with recesses or for linking precast units with in-situ concrete. The galvanized steel box eliminates the need for extra formwork, while the flexible wire loops are released easily with tear-off tape. Once extended, the loops are reinforced with steel bars and concrete, ensuring a durable, load-bearing joint.
Manufactured from high-performance galvanized steel plate through stamping and welding, offering corrosion resistance and stability.
Made from high-strength steel wire rope, ensuring dependable load-bearing performance.
The steel wire rope is cut to length, with both ends threaded outward through holes in the box. After aligning, the ends are compressed into an aluminum sleeve for secure fixation. The folded section is hidden inside the box, sealed with adhesive tape to prevent concrete ingress during casting. This ensures a clean, easy-to-use product on-site.
The capacities presented in the tables below are calculated for static loads. Our wire rope loops are not designed to be used for dynamic loading or for lifting. For the capacities to be achieved, there should be no cracks or deformations in the joints.
The capacities of the wire rope loops are calculated for a joint as presented in the diagram with seam thickness and reinforcement as outlined in the following sections. The steel boxes and the seam must be fully filled with concrete.
The capacities given are the resistances in ultimate limit state, so please compare to design loads.
The resistance is defined by the weakest concrete in the joint (element/joint concrete). Resistances are calculated for concrete classes C25/30, C30/37 and C40/50.
All HULK Metal precast wall connection wire loop boxes are CE and ISO 9001 certified, guaranteeing compliance with international quality and safety standards.
When HM wire loop boxes are used to transfer forces in the joint, anchorage of the wire loop box must be secured by overlapping the wire loop box sufficiently with the reinforcement of the concrete element. This should be done to the engineer's design depending on your precise arrangement.
Where the wire loop is used in a corner joint a reinforcing bar should be installed into the inner edge of the fold of the HM wire loop box, the diameter of this bar should be the same as the reinforcement installed in the joint.
When wire loops boxes are used to limit cracking of the seam or to tie elements together without defining the required force, additional reinforcement in the wall is recommended as shown here, including 2 No 10mm diameter additional bars in each piece.
The wire rope loop box must be attached securely so it cannot move during casting of the concrete. At the wire rope loop, the concrete must be compacted carefully as the loop cannot be vibrated. The wire rope loops boxes may be fastened to formwork with nails or by magnets.
The part of the wire rope which enters the concrete element is installed amidst the reinforcement and does not need to be tied to the reinforcement.
