Abstract
Abstract Light steel joists may be spaced 24 inches o.c. under ceramic tile floors when floor bracing members are spaced at 16 inch o.c. intervals between the joists under such floors. Also made of light gauge steel, the bracing member is slotted to receive a return flange of a channel-shaped joist so that the tops of the joists and bracing members are co-planar.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
159 words
A floor assembly comprising a ceramic tile overlay; a sub-floor to which the ceramic tile overlay is bonded; a horizontal array of spaced-apart, parallel, C-shaped metal joists which serve as the major support for the sub-floor, each joist having an upright web portion, upper and lower flanges spaced apart by and extending horizontally away from the web, a pendant return flange extending perpendicularly from the upper horizontal flange; and a plurality of floor bracing members connecting adjacent joists at right angles to each, each floor bracing member comprising a web, a flange co-planar with the upper flange of an adjacent joist and extending perpendicularly in such plane from a lateral edge of the web, the flange and web of the bracing member having a common slot which receives the pendant return flange of the joist, and two connector plates, one at each longitudinal end of the web, which abut the upright webs of adjacent joists and are fastened thereto.
Claim 2
Dependent Claim
159 words
A floor assembly comprising a ceramic tile overlay; a sub-floor to which the ceramic tile overlay is bonded; a horizontal array of spaced-apart, parallel, C-shaped metal joists which serve as the major support for the sub-floor, each joist having an upright web portion, upper and lower flanges spaced apart by and extending horizontally away from the web, a pendant return flange extending perpendicularly from the upper horizontal flange; and a plurality of floor bracing members connecting adjacent joists at right angles to each, each floor bracing member comprising a web, a flange co-planar with the upper flange of an adjacent joist and extending perpendicularly in such plane from a lateral edge of the web, the flange and web of the bracing member having a common slot which receives the pendant return flange of the joist, and two connector plates, one at each longitudinal end of the web, which abut the upright webs of adjacent joists and are fastened thereto.
Claim 3
Dependent Claim
32 words
The floor assembly of claim 1 wherein the connector plates of the bracing member extend perpendicularly away from the web thereof and in the opposite direction with respect to the flange thereof.
Claim 4
Dependent Claim
29 words
The floor assembly of claim 1 wherein the floor bracing member is generally channel shaped, having a second perpendicular flange spaced apart from and parallel to the slotted flange.
Claim 5
Dependent Claim
31 words
The floor assembly of claim 1 wherein the flange and web of a floor bracing member have two common slots equidistantly spaced from the longitudinal ends of the floor bracing member.
Claim 6
Dependent Claim
24 words
The floor assembly of claim 4 wherein only one slot of a floor bracing member is occupied by a return flange of a joist.
Claim 7
Dependent Claim
142 words
A floor assembly comprising a horizontal array of spaced-apart, parallel, C-shaped metal joists which serve as the major support for a sub-floor, each joist having an upright web portion, flanges spaced apart by and extending horizontally away from the web, and return flanges extending toward each other perpendicularly from each horizontal flange; and a plurality of floor bracing members connecting adjacent joists at right angles to each, each floor bracing member comprising a web, a flange co-planar with the uppermost flange of an adjacent joist and extending perpendicularly in such plane from a lateral edge of the web, the flange and web of the bracing member having a common slot which receives a return flange of the joist, and two connector plates, one at each longitudinal end of the web, which abut the upright webs of adjacent joists and are fastened thereto.
Claim 8
Dependent Claim
142 words
A floor assembly comprising a horizontal array of spaced-apart, parallel, C-shaped metal joists which serve as the major support for a sub-floor, each joist having an upright web portion, flanges spaced apart by and extending horizontally away from the web, and return flanges extending toward each other perpendicularly from each horizontal flange; and a plurality of floor bracing members connecting adjacent joists at right angles to each, each floor bracing member comprising a web, a flange co-planar with the uppermost flange of an adjacent joist and extending perpendicularly in such plane from a lateral edge of the web, the flange and web of the bracing member having a common slot which receives a return flange of the joist, and two connector plates, one at each longitudinal end of the web, which abut the upright webs of adjacent joists and are fastened thereto.
Claim 9
Dependent Claim
32 words
The floor assembly of claim 6 wherein the connector plates of the bracing member extend perpendicularly away from the web thereof and in the opposite direction with respect to the flange thereof.
Claim 10
Dependent Claim
29 words
The floor assembly of claim 6 wherein the floor bracing member is generally channel shaped, having a second perpendicular flange spaced apart from and parallel to the slotted flange.
Claim 11
Dependent Claim
31 words
The floor assembly of claim 6 wherein the flange and web of a floor bracing member have two common slots equidistantly spaced from the longitudinal ends of the floor bracing member.
Claim 12
Dependent Claim
24 words
The floor assembly of claim 9 wherein only one slot of a floor bracing member is occupied by a return flange of a joist.
