Connection Loop Boxes

Features of HULK Metal Connection Loop Boxes:

• Design Principles of HULK Metal Connection Loop Boxes:

  Component Breakdown

  
  

  The Connection loop box is composed of three key parts:

  

  Compression Sleeve (20# Steel)

  
  

  Crafted from high-quality 20# steel, the compression sleeve delivers outstanding strength and durability. Its precise design keeps the wire loop securely in place, ensuring long-term stability and dependable performance, even under heavy loads in concrete connections.

   

  Wire Loop (High-Strength SE-Zn Steel Wire Rope)

  
  

  The wire loop is made from SE-Zn coated high-strength steel wire rope, offering excellent tensile strength and corrosion resistance. This guarantees safe and efficient load transfer between concrete elements, while maintaining flexibility and reliability in both indoor and outdoor applications.

   

  Box (Galvanized Steel Sheet)

  
  

  Manufactured from premium galvanized sheet steel, the box provides superior resistance to rust and environmental impact. It effectively protects the embedded wire loop while maintaining precise dimensions for smooth integration into precast concrete components during manufacturing and installation.

  
  

  How Connection Loop Boxes Work

  
  

  Connection Loop Boxes are designed to create strong and reliable joints in precast construction through a simple and efficient process:

  
  

  1. Integration During Production

  
  

     A steel box with wire loops is embedded directly into the precast concrete element during manufacturing.

  
  

  2. Safe Storage

  
  

     The loops remain neatly protected inside the box with a cover, ensuring they stay secure until installation.

  
  

  3. Quick On-Site Activation

  
  

     When needed, the adhesive tape is removed, and the loops are easily unfolded for connection.

  
  

  4. Rebar Integration

  
  

     Reinforcing bars are threaded through the loops, securely linking adjoining elements.

  
  

  5. Final Bonding

  
  

     Fresh concrete is poured, creating a strong, monolithic connection with excellent stability and load-bearing capacity.

  
  

  
  

  This method simplifies installation, saves time on site, and guarantees long-term structural integrity for modern construction projects.

• Installation of HULK Metal Connection Loop Boxes:

  Case 1 – Where wire loops are used to transfer forces

   

  When HM wire loop boxes are used to transfer forces in the joint, the 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 according 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.

   

  Case 2 – Where HM wire loops are not used to transfer forces

  
  

   

  
  

  When wire loops boxes are used to limit cracking of the seam or to tie elements together without establishing the required force, additional reinforcement in the wall is recommended, as shown here, including 2 additional 10mm diameter bars in each piece.

   

  Attachment to the formwork:

   

  The wire rope loop box must be securely attached so it cannot be moved during concrete casting. The concrete must be compacted carefully to prevent vibration. The wire rope loop boxes may be fastened to the formwork with nails or magnets.

  
  

  The portion of the wire rope that enters the concrete element is installed adjacent to the reinforcement and does not need to be tied to the reinforcement.
