Description

Head Restraints

Ancon Head Restraints provide the necessary restraint to the top of masonry walls. They allow for vertical movement to accommodate shrinkage or thermal movement of the wall or structural frame, while restraining wind loads.

Ancon IHR – Internal Head Restraint

The Ancon IHR is used for restraining the top of internal walls or the top of the inner leaf of a cavity wall. The channel stem is closed at the front to prevent mortar ingress and to ensure that vertical movement can take place between the blockwork and the structure.

An IHR comprises a sliding top section and a stem. The standard length of an IHR sliding top section will accommodate a gap of up to 50mm. Longer top sections are available to accommodate gaps of up to 75mm, ideal when a fire stop is being incorporated at the wall head or where greater deflection is expected in the floor.

The standard Ancon IHR stem will suit a 215mm high block. IHR stems for taller block heights are available on request, however in such cases the stem may not be able to accommodate a gap above the block of more than 40mm.

The sliding tie can be provided with a hole (IHR-B) or slot (IHR-V) to suit M8 bolts, with a notch end to fix directly into a 38/17 or 30/20 cast-in channel (IHR-C), and with a notch end to suit the Hammer-On section that attaches to a steel flange without site drilling (IHR-H). It is also available to suit the SDTSS-38-5PT self-tapping screw (IHR-S).
