Plural-story building structure with floor-bypass utilities infrastructure

Abstract

A plural-story building structure including spaced lower and higher stories, with the lower story possessing a normal, unimpeded, full plate-height internal volume which is free of any exposed, ceiling-penetrating utilities-conduit structure designed for the supply of utilities services to upper stories. This lower story is thus available, early in the time of overall building construction, and specifically with upper stories still under construction, for income-generating occupancy. The special, unoccluded, full plate-height, internal-volume condition is accommodated by the interposition, between the mentioned lower and higher stories, of a special, low-height, sub-story in the form of a utilities-conduit containment space which is adapted to contain utilities-conduit structure relevant to the supply of utilities services upwardly from the sub-story toward higher stories. Utilities supply to the sub-story bypasses the mentioned lower building story.

1 . A plural-story building structure comprising 
 a pair of vertically spaced stories including a lower story and a higher story, with each possessing a normal full plate-height internal volume, and with the lower story additionally being characterized by an internal volume which is defined, at least in part, by an unimpeded full plate-height, and    a utilities-conduit containment space in the form of a sub-story disposed independently and directly vertically intermediate said lower and higher stories, possessing a less than normal full plate-height internal volume, and adapted to contain utilities-conduit structure relevant to the supply of utilities services upwardly from said containment space toward said higher story, with related utilities services supply to said utilities-conduit structure extending thereto in a manner avoiding any presence within the mentioned internal volume of said lower story.    
   
   
       2 . The building structure of  claim 1 , wherein said containment space is appropriately lined against the possibility of liquid drainage taking place from its internal volume to that of said lower story.  
   
   
       3 . The building structure of  claim 1 , wherein said lower story is a ground-level story.  
   
   
       4 . A plural-story building structure comprising 
 a pair of vertically spaced stories including a lower story and a higher story, with each possessing a normal full plate-height internal volume, and with the lower story additionally being characterized by an internal volume which is defined, at least in part, by an unimpeded full plate-height,    a utilities-conduit containment space in the form of a sub-story disposed independently and directly vertically intermediate said lower and higher stories, possessing a less than normal full plate-height internal volume, and adapted to contain utilities-conduit structure relevant to the supply of utilities services upwardly from said containment space toward said higher story,    utilities-conduit structure disposed within said containment space including supply-input portions adapted for connection to related utilities services supplies which are external to the building structure, with such connection adaptation accommodating interconnection between said utilities-conduit structure and such external supplies in a manner avoiding any presence within the internal volume of said lower story.    
   
   
       5 . The building structure of  claim 4 , wherein said containment space is appropriately lined against the possibility of any liquid drainage taking place from its internal volume to that of said lower story.  
   
   
       6 . A plural-story building structure comprising 
 a vertical stack of stories including plural normal-height stories, and disposed vertically intermediate at least two of these stories, a less-than-normal-height sub-story, with the lower one of said at least two stories possessing an internal volume with an unimpeded full plate height, and,    an internal volume of spaced formed in said sub-story, adapted to contain utilities-conduit structure relevant to the supply of utilities services upwardly from said sub-story toward the higher one of said at least two stories, with related utilities services supply to said utilities-conduit structure extending thereto in a manner avoiding any presence within the internal volume of the said at least two stories.
