Composite joist floor system

摘要

Embodiments of the present invention provide systems for connecting a flooring system to a vertical wall. In one embodiment the building structure includes a floor comprising a cementitious slab and a wall supporting at least a portion of the cementitious slab. A plurality of stand-off fasteners extend from the top of the wall into the cementitious slab and are configured to transfer forces between the cementitious slab and the wall. The stand-off fasteners comprise a lower portion and an upper stand-off portion. The lower portion is operatively coupled to the top of the wall, and the upper stand-off portion extends above the top of the wall and is encapsulated within the cementitious slab. In some embodiments, at least a portion of the lower portion is heat treated to a higher degree of hardness relative to the remainder of the stand-off screw.

主权项

1. A building structure comprising:
a first supporting structure; a second supporting structure; a plurality of floor joists supported between and operatively coupled to the first supporting structure and the second supporting structure, wherein each of the plurality of floor joists comprise:
an upper chord;a lower chord;a joist shoe on at least a first end of the floor joist, and wherein the joist shoe is located between the upper chord and the lower chord and extends over and is operatively coupled to the first supporting structure beyond at least a portion of the upper chord of the floor joist, wherein the joist shoe is spaced apart from the upper chord and the lower chord; anda web operatively coupled to at least the upper chord and the lower chord; a plurality of joist shoe fasteners, each configured to operatively couple the joist shoe of the plurality of floor joists to the first supporting structure, wherein the joist shoe extends beyond at least a portion of the upper chord of the floor joist to provide sufficient room for utilizing a tool to operatively couple the joist shoe of the plurality of floor joists to the first supporting structure; decking operatively coupled to the plurality of floor joists; a closure extending between the first supporting structure and the decking forming a channel; and wherein a cementitious slab is formed within the channel and above the decking that encapsulates at least a portion of the upper chord and at least a portion of the joist shoe of the plurality of floor joists, and at least a portion of the plurality of joist shoe fasteners.
