047 – r3 - Vermiculux Beam & Column Encasement - Interface with Fire Rated Partition

® VERMICULUX Detail for Beam and Column Encasement to Fire Rated Partition Interface Introduction: ®VERMICULUX is a lightweight non-combustible board specially designed to provide up to 240 minutes fire protection to structural steelwork. The following recommendations should be adopted where a fire rated partition system, running in the ®same plane as a VERMICULUX protected steel beam, is connected to the underside of the beam or ®where a fire rated partition system is connected to one or both flanges of a VERMICULUX protected steel column. Construction Details: • The steel Z brackets, 0.9mm to 1.2mm thick with flanges 32mm wide (1), are fastened to the beam or column flange (2) with shot fired 3.7mm x 16mm steel nails (Hilti ENK 16 S12 or equivalent) at 300mm maximum centres. The Z brackets are the same length as the width of the beam/ column and are spaced at 600mm nominal centres along the length of the flange. • The dimension of the web of the Z brackets should be made 6mm longer than the thickness of the ® ®VERMICULUX , to allow for a tolerance between the flange of the beam and the VERMICULUX board (the web of the Z bracket should be 3mm longer where used for a column). The width of the ® should be cut 6mm wider than the width of flange of the beam/column, to allow for ®a 3mm tolerance between the web of the beam/column and the VERMICULUX cheek boards. • When connecting to a column, the steel starter stud channel is ...
