Anchor Channels and Sections INTRODUCTION
Sampag anchor channels consist of c-shaped sections of varied capacity for diverse fastening applications. When cast into concrete or secured to structures, they can support load points of up to 35.0 kN. Fixing to channel is made with tee-headed bolts that can be inserted into the slot and moved freely along the channel length to fixing positions. This particular feature offers high fixing flexibility and compensates for tolerance variations when it comes to construction of secondary building systems, e.g. curtain-walls, façade claddings, building services etc.
And because channel units can support multiple loads at close spacing, and that they do not generate expansive forces in the concrete, fixings can be at close centers and located closer to the edges than is possible with conventional anchors.
In short, fastening by anchor channel is convenient and cost effective. Its application facilitates the installation process, and eliminates the need for sophisticated tooling and operation.

Anchor Channels and Sections
Sampag cast-in anchor channels are delivered with nail holes and foam-filler to facilitate fixing to formworks, and to prevent ingress of concrete. Nailing to planks should be secured to avoid displacement at pouring. Channel units should also be aligned and leveled to ensure a flush surface after striking.

INTRODUCTION
Tee-bolts inserted are turned through 90 degrees to engage properly with the channel. This position is indicated by a perpendicular notch direction to the long channel axis. Component brackets can then
be positioned and tightened down to appropriate torque. As an alternative to tee bolts, channel nuts are commonly used for non-standard thread sizes and lengths.
Anchor channels are normally supplied in custom lengths where last anchors are located at 25mm center to the cut edges.
When cutting to shorter lengths is necessary, it is important to leave a whole anchor within the prescribed distance. Add anchor TEK if end distance is any longer.

The load information in this catalogue is statistically derived from tests of finished products carried out in accordance with international engineering procedures. Load capacities of different items are expressed in their tension and shear components in regard to the channel axes to facilitate comparison with proposed working loads.
The load capacities of anchor channels are based on their characteristic performance in normal weight aggregate C30 (characteristic strength 30.0 Mpa) where working loads are applied to the ultimate strength of the channel component or the base concrete. This level represents the maximum load limit of the fixing system.
Tee Bolts will develop the full capacity of the thread diameters. They can be selected at the User’s discretion by observing following requirements:
• Only the profile designated fasteners can be used; and• Working loads of which must not exceed that of the anchor channel.
The Allowable Loads in this manual will ensure a minimum factor of safety of 3.0 against failure.
In every case, User should ensure proper design of the supporting concrete structure.
Customers unsure of the design parameters adopted in this catalogue should refer to Sampag for clarifications.

Reduced Edge DistanceDesign constraints on thin-wall structures can be overcome by adding reinforcement to the base concrete. By proper dimensioning the rebar loops as shown in Figure 1, arrangement can support full tensile capacity of unit at edge distance reduced down to 50mm.
For guidance on design of the supporting structure please consult statutory code of practice concerning “Safe Use of Concrete”, or contact Sampag for assistance.

Channel load data are results of tests in un-reinforced normal weight concrete. To develop these loads, additional reinforcement is normally
not required. For use in concrete of lower strengths, the allowable values from Table should be reduced using the following empirical formula:

Sampag anchor channels are suitable for use under dynamic conditions. When subjected to vibrations, part of the anchoring capacity is expended to counteract the dynamic effect dependent on the load cycles, N and its amplitude. Reduction factors in following table can be used
to convert static capacity of anchor components into an equivalent dynamic capacity. Alternatively, when the amplitude at given load cycle is provided, resulting dynamic capacities can be obtained directly from the allowable loads.

GENERAL APPLICATIONS
Sampag anchor channels are used where fixing of building components is required to transfer the working loads onto supporting structures. Following illustrations depict some of the many applications found in modern building and construction industries today:
• Glazed Curtain Walls• Facade Claddings• Building Services• Lift Guide Rails• Pre-cast Elements• Masonry Stonework......
