Abstract

A system and method of constructing a composite floor system having increased shear transfer between a slab and support members of the system is described. The composite floor system may include any combination of the following elements: a support member, a reinforcing member, a transfer member, a decking material, a fastener, and/or a slab. The transfer member may be connected to the support member.

Claims (30)

1. A composite floor system, comprising:

a slab;

a deck material sized and shaped to support said slab;

a support member positioned below said deck material; and

a transfer member attached to said support member, said transfer member including an elongated body having a bottom with a first edge and a second edge opposite said first edge, a first side wall extending upwardly from said first edge of said bottom, and a second side wall extending upwardly from said second edge of said bottom, said transfer member sized and configured to increase transfer of shear forces between said slab and said support member;

wherein said transfer member defines bottom and side walls, and wherein cutouts are defined in the bottom and side walls to closely cooperate with said deck material; and

wherein the transfer member is embedded in the slab such that the slab substantially surrounds the transfer member.

2. The composite floor system of claim 1 , wherein said transfer member is attached directly to said support member.

3. The composite floor system of claim 2 , wherein said transfer member is cold-formed and said support member is cold-formed.

4. The composite floor system of claim 3 , wherein said deck member is positioned permanently above said support member and is non-removable.

5. The composite floor system of claim 4 , wherein said deck material has a length, and said support member has a length, said length of said deck member is substantially the same as said length of said support member.

6. The composite floor system of claim 1 , wherein said transfer member is a furring channel made of steel.

7. The composite floor system of claim 1 , further comprising a reinforcing bar positioned on top of said transfer member, said reinforcing bar being perpendicular relative to said transfer member, said reinforcing bar sized and shaped to prevent transverse cracking in said slab.

8. The composite floor system of claim 1 , wherein said support member includes a first metal joist having a first side wall and a second metal joist having a second side wall, said first side wall positioned proximate to said second side wall.

9. The composite floor system of claim 8 , wherein said first joist and said second joist are substantially C-shaped.

10. The composite floor system of claim 9 , wherein said transfer member is attached directly to said first joist and to said second joist through welding.

11. The composite floor system of claim 1 , further comprising a hanger sized to support said support member.

12. The composite floor system of claim 11 , wherein said hanger includes a main wall, a top wall protruding from said main wall in one direction, and a bottom wall protruding from said main wall in an opposite direction.

13. The composite floor system of claim 12 , wherein said hanger includes a pair of brackets protruding from said main wall, said pair of brackets including apertures.

14. The composite floor system of claim 11 , wherein said hanger includes a top wall, a first main wall connected to said top wall, a second main wall connected to said top wall, a first bracket protruding from said first main wall, and a second bracket protruding from said second main wall.

15. A composite floor system comprising:

a slab;

a deck material sized and shaped to support said slab;

a support member attached to said deck material, said support member including a first beam with a first side wall having a first top edge and a first bottom edge, said first beam including a first flange extending from said first top edge of said first side wall, and a second beam with a second side wall having a second top edge and a second bottom edge, said second beam including a second flange extending from said second top edge of said second side wall, said first side wall positioned proximate said second side wall; and

a transfer member attached to said deck material and said support member and sized and configured to increase transfer of shear forces between said slab and said support member;

wherein said transfer member defines bottom and side walls, and wherein cutouts are defined in the bottom and side walls to closely cooperate with said deck material; and

wherein the transfer member is embedded in the slab such that the slab substantially surrounds the transfer member.

16. The composite floor system of claim 15 , wherein said first beam is substantially C-shaped, and said second beam is substantially C-shaped.

17. The composite floor system of claim 16 , wherein said first beam and second beam include openings formed in said first and second side walls.

18. The composite floor system of claim 17 , wherein said transfer member includes a elongated, trough-like body.
