Description
Tenn PFA Drop-In Anchor consists of a cylindrical shell with an internally threaded section (Fig. 1a) leading to an internally tapered expansion section (Fig. 1b). A tapered expander cone (Fig. 1c) is pre-filled inside the shell A plug retention system prevents the expander cone from dropping out.
The shell has four longitudinal slots (Fig. 1d) to facilitate expansion.
An integral part of this anchor system is the setting punch. This setting punch (Fig. 2) is used to farce the expander cone to the base of the anchor. A specific setting punch is used for each size of PFA Anchor The punch is so designed that the expander cone will not be driven out of the anchor shell.
Advantages
Tenn PFA Drop-In Anchors’ shallow embedment depths mean that most sizes may be set in the concrete cover above the steel reinforcement. This makes PFA anchors ideal for use in concrete deck undersides for the suspension of services, pipework, ductwork, cable tray, ceilings etc.
PFA anchors are also useful in floors such as for mounting machinery. Due to flush installation there are no projecting studs to get in the way when the machinery has to be moved.
