Anchor channel, also called cast-in channels, are pre-installed components. They are fixing parts which are used to fasten devices.

Note) PAC uses the steel plate with the appropriate weldability.

PAC has more improved anchorage performance than stud-type because of its geometric characteristics of the head embedded in the concrete

1) Anchor Head - More long & parallel perimeter for Effective Anchorage.

The critical factor for low bearing pressure is local crushing area(red zone) is strongly affected by the geometric perimeter. And long & parallel perimeter under the anchor head, especially adjacent to axis. Plates-welded anchor head completely satisfies this requirements. And this is especially useful for safety relevant area in nuclear facilities.

2) Channel - Shear force parallel to an edge causes concrete breakout. And the concrete failure is generally influenced with the channel depth and edge distance.

The newly added sub-anchor allows much more loads to be taken up at edge zones where shear loads occur. This not only increase ability for shear loads, but also simplifies planning works. The system, furthermore, provides a lasting high flexibility during the entire useful life of the building.

Self-Standing

PAC can be self-standing on the bottom-formwork using the spacer. This is stable and more effective to install regardless of field conditions. And then it is fixed with tying wire to rebars. It does not need fixing to form-work.

Size-flexibility

It’s effective that steel plate is cut to pieces by press. Anchor stem is solidly welded to channel and head plate.

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.

Applicaion of PHB - the coupler function for rebar splicing as well as anchoring.
