Abstract
This patent discloses a method and apparatus for activation of services in a concrete floor of an office building from below floor slab distribution systems. Void-forming boxes that are secured to a conventional metal deck sheet and surrounded by the concrete floor slab provide chambers in which in-floor activations are mounted. An insulating block in the void-forming box restores fire resistance, prior to installation of an activation kit, that is lost by displacement of concrete by the void-forming box. An in-floor activation kit may be installed within the void-forming box and connected to a below floor slab distribution system through an activation opening cut in the metal deck sheet. Connection hardware is secured to the metal deck sheet for connection to a conventional below-floor slab service distribution system providing communication from the interior of the void-forming box to the below-floor slab service distribution system. Void-forming boxes mounted to the metal deck sheet may be connected by conduit in a conventional manner allowing conductors to be routed from a void-forming box connected to a below floor slab service distribution system to another void-forming box t…
