Features of HULK Metal Wire Loop Box:

  • Design Principles of HULK Metal Wire Loop Box:

    Wire Loop Box

    l 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.

    l 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.

    l The capacities given are the resistances in the ultimate limit state, so please compare them to design loads.

    l 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.

    Combined Forces:

    For circumstances where there is a combination of forces on the wire loop joints, the following must apply:

     

    VApplied / VRd    =    FApplied /  FRd   =   NApplied / NRd < = 1

  • Installation of HULK Metal Wire Loop Box:

    The wall elements must be reinforced according to the wall element design.


    Seam Thickness:

    The size of the wire rope loops must be chosen according to the thickness of the joint to enable the vertical ribbed steel bar in the joint to pass through the wire rope loops on both sides of the joint.

    Case 1 – Where wire loops are used to transfer forces.

    When HM wire rope loops are used to transfer forces in the joint, the anchorage of the wire rope loop must be secured by overlapping the wire rope loop 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 RVL wire rope loop, 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 rope loops 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.


     

    Attachment to the formwork:

    The wire rope loop box must be attached securely so it cannot move during the casting of the concrete. At the wire rope loop, the concrete must be compacted carefully as the loop cannot be vibrated. The wire rope loop boxes may be fastened to formwork with nails or by magnets.

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