Fixings to Metal Decks, Beams and Purlins
Joint JOI R
Application
The Joint JOI R is used for bracing of channel installations which are of central importance to seismic support of services. Due to its keyhole shaped design the joint can be retrofitted. For installing directly to Channel 41 the four pins and two fixing points guarantee a reliable rotation lock. Brackets can be stacked for bracing longitudinally and transversely.
The rotation lock for the installation to an existing structure depends on the already used components. In case of the application of a Block PB 41 a rotation lock is given. In case of the application of a Holding Bracket or a Washer a rotation lock is only partly given.
