Description

2~ 4~11 INTERFLOOR POWER/COMMUNICATION CONNECTION APPARATUS

This invention relates generally to apparatus and methods for the transmission of electrical power and .~ Icommunication si~nals from one building floor to another and . pertains more particularly to so-called "poke-thru" devices .; I adapted for disposition in passages formed through concrete floors.
I
¦ BACKGROUND OF THE INVENTION

lO ¦ ~Ir!e~e has been extensive prior art activity in the pursuit of averting the use of on-floor conduits for conveying electrical power and communication lines to floor locations . which were not within the original architectural and electrical ., planning o~ a facility, such as a multi-floor concrete .
15 building. Such on-floor conduits are in the first place ~.
i aesthetically unpleasant and secondly can give rise to personnel .l danger, such as by tripping over the same.
While the art has averted these problems in the introduction of flat undercarpet cable installations, the ~ 20 problem remains extant in the use of the conventional dLscrete ::~ wiring systems in place in general in existing buildings and for many currently-planned facilities for which the undercarpet approach is not elected.

~il 4a2C~

1 In ~he conventional discrete installations, the problem under discussion has been addressed by drilling a passage through the concrete floor and c:onducting power and/or c~ unication signals from a lower floor to the floor in which a i new power and/or communication signal outlet is desired.
B Electrical safety codes have place~two sanctions on such activity. Firstly, it is essential that the installed transition apparatus not function as a chimney or fire-advancing flue in the event of fire occurrence on the lower floor.
¦ Secondly, it is imperative that the transition apparatus not function as a conductive heat channel between floors.
The industry has largely met these requirements through the use of intumescent material in the transition apparatus, such material expanding under fire conditions against the concrete circumscribing the passage to effectively block the pre-existing flue which may have been present in the passage.
Further, the art has reached structures which have conductive heat blocking members, i.e., synthetic spacers, disposed axially between and separating conductive heat communication between 20 heat conductive members of the apparatus. -~
Presently known transition apparatus is seen as lacking versatility in respect of the types of pedestals which may be used therewith. Thus, two di~erse types of pedestals a~e in widespread use, i.e., the fl~sh-m~unt pedestal and the 25 low-profi~e pedestal, the latter protruding upwardly of the ~ ;

.
~'', 1 I r loor to an extent and the former being essentially continuous with the floor. Known transition devices thus are designed to be dedicated to one or the other of the pedestal types, necessitating matching thereof, increased inventory and other ¦ disadvantages.
