Abstract:
A fire-rated container apparatus mountable in a volumetric space formed between structural and false ceilings spaced apart from each other by supporting members, the structural and false ceilings separated by a volumetric space height and the false ceiling including a false ceiling hole that provides an access opening to the volumetric space, comprising:a ceiling ring attachable to the false ceiling and having a ring opening that upon attachment is positioned relative to the false ceiling hole to provide access to the volumetric space; multiple support straps each of which having a first end and a second end, the support straps at first locations nearer to the first ends being securable to the ceiling ring in angularly spaced-apart relation and the support straps at second locations nearer to the second ends being adaptable for an operative structural connection to the structural ceiling; a housing including structural ceiling and open lower end portions and having an outer surface and a length, the length of the housing when inserted into the ring opening and set in the volumetric space exceeding the volumetric space height so that the lower end portion protrudes outwardly from the false ceiling; a spacing collar configured to surround the lower end portion and cover the outer surface that protrudes outwardly from the false ceiling and securable to the ceiling ring to fixedly set the housing in the volumetric space; and a cover piece adapted for operative structural connection to the lower end portion to cover it.
