Abstract
A composite flooring system includes a cross-laminated timber (CLT) subfloor including a plurality of drop holes, a plurality of isolators disposed on top of and attached to the CLT subfloor, a sprinkler main of a sprinkler system disposed between the plurality of isolators, a plurality of sprinkler drops attached to the sprinkler main which extend through the drop holes of the CLT subfloor, a plurality of metal inverted tracks attached to a top surface of the plurality of isolators, and an upper flooring attached to a top surface of the metal inverted tracks.
Claims19
A composite flooring system comprising:
- a cross-laminated timber (CLT) subfloor including a plurality of drop holes;
- a plurality of isolators disposed on top of and attached to said CLT subfloor;
- a sprinkler main of a sprinkler system disposed between said plurality of isolators;
- a plurality of sprinkler drops attached to said sprinkler main which extend through said drop holes of said CLT subfloor, wherein a sprinkler head of said sprinkler drop is disposed entirely below said CLT subfloor;
- a plurality of metal inverted tracks attached to a top surface of said plurality of isolators, such that one of said plurality of metal inverted tracks is attached to multiple of said plurality of isolators which are spaced apart from one another;
- and
- an upper flooring attached to a top surface of said metal inverted tracks, wherein a space between said CLT subfloor and said upper flooring is filled with a foam or fiberglass insulation which abuts each of said plurality of isolators.
A composite flooring system comprising:
- a cross-laminated timber (CLT) subfloor including a plurality of drop holes;
- a plurality of isolators disposed on top of and attached to said CLT subfloor;
- a sprinkler main of a sprinkler system disposed between said plurality of isolators;
- a plurality of sprinkler drops attached to said sprinkler main which extend through said drop holes of said CLT subfloor, wherein a space between an outer edge of said drop holes and said sprinkler drops is filled with a layer of intumescent caulk and a gypsum filler, such that said intumescent caulk fills a bottom inch of said space, and said gypsum filler fills the remainder of said space;
- a plurality of metal inverted tracks attached to a top surface of said plurality of isolators;
- and
- an upper flooring attached to a top surface of said metal inverted tracks.
A method of assembling a composite flooring system comprising:
- providing a cross-laminated timber (CLT) subfloor;
- drilling a plurality of drop holes through the CLT subfloor;
- attaching a plurality of isolators to a top surface of said CLT subfloor;
- disposing a sprinkler main of a sprinkler system between said plurality of isolators;
- disposing a plurality of sprinkler drops of said sprinkler system through the drop holes;
- attaching a plurality of metal inverted tracks to a top surface of said plurality of isolators;
- attaching an upper flooring to a top surface of said metal inverted tracks;
- filling a space between an outer edge of said drop holes in said CLT subfloor and said sprinkler drops with a layer of intumescent caulk, such that said intumescent caulk fills a bottom inch of said space;
- and
- filling a remainder of the space between the outer edge of said drop holes in said CLT subfloor and said sprinkler drops with a gypsum filler.
