Electrical service conduit system and method of use

Abstract

A system and method to route electrical service conduits through the interior of a building and also to comply with the National Electrical Code(NEC). The system includes the use of a two inch concrete encasement which is reinforced by metal plates. A lower portion of the concrete encasement has a flat metal bar therein for mounting to rods extending from a secure ceiling area of a building. The protective nature of the encasement enables the service conduit to be designated as outside of a building and thus in compliance with NEC standards.

1 . A-method of encasing an electrical supply conduit and running said conduit through a building having a solid and secure ceiling area comprising the steps of: 
 a) suspending a plurality of rod elements from said solid and secure ceiling area,    b) attaching a lower encasement structure to said rod elements, said lower encasement structure comprising a two inch thick curved shell element and including a straight steel reinforcing bar means for attachment to said rod elements, 
 said lower encasement structure further including a curved reinforcing steel bar means having end portions which extend outside of said lower encasement structure,  
   c) placing at least one electrical supply conduit within said lower encasement structure, wherein said electrical supply conduit is contained within a plastic pipe,    d) providing an upper encasement structure, said upper encasement structure comprising a two inch thick curved shell element and including a curved reinforcing steel bar means having end portions which extend outside of said upper encasement structure,    e) providing attaching means for connecting the lower encasement structure to the upper encasement structure.    
   
   
       2 . The method of  claim 1  wherein said lower encasement structure and said upper encasement structure are fabricated of concrete which includes a foamed material to provide a light weight overall structure.  
   
   
       3 . The method of  claim 2  wherein, in the lower encasement structure, the straight steel reinforcing bar means is welded to the curved reinforcing steel bar.  
   
   
       4 . In combination with the interior ceiling area of a building structure, an encasement system combined with electrical service entrance conduits comprising: 
 a lower encasement being curved and formed of foam impregnated lightweight concrete,    an upper encasement being curved and also formed of foam impregnated lightweight concrete,    said lower and upper encasements having curved reinforcing steel bars therein,    said lower encasement further having a straight reinforcing steel bar therein,    a plurality of rods extending from a solid and secure area of the ceiling,    said lower encasement structure being attached to said rods,    said upper encasement structure being attached to said lower encasement structure.    
   
   
       5 . An encasement system for use with electrical service conduits, 
 said system including an upper encasement structure fabricated of concrete,    a lower encasement structure fabricated of concrete,    means for joining said upper and lower structures together.    
   
   
       6 . The encasement system of  claim 5  and further including means for suspending said encasement system for a ceiling.  
   
   
       7 . The encasement system of  claim 6  and further including reinforcing bar means placed in pre-cast concrete for installation in a building and for routing an electrical supply conduit through a building in compliance with an electrical code.
