The headed bar is a rebar technology development for anchoring without bending the rebar.

Mechanical Splicing of PHB (bolting joint)

  • As shown in the diagram, the mechanical splicing of rebar is possible with high tension bolts.
  • This is especially useful in columns, which use thick rebar.
  • The PHB bolting joint method improves constructability and cost.
  • The conventional rebar spice is either a lap splice or a using coupler instead of bolts.

PHB’s Economy

As shown in the picture, PHB has its characteristic of continuously welding facilities with a shor time and low cost suitable for mass production. Manufacturing Methods, by rotating the anchor head and friction welding to the end of the rebar or by hot compressing the end of the rebar and then molding the head as one piece, produce headed bar individually.
