Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
170 words
A framed concrete slab structure comprising at least one girder having an upper surface, at least one joist intersecting said at least one girder along the upper surface of said at least one girder, said at least one joist being supported by the upper surface of said at least one girder, and continuous deck means disposed to rest on said joist spaced above said girder by said joist and adapted to receive poured concrete thereon, shear connector mounting means mounted on said upper surface of said at least one girder and spaced away and separate from said joist, said shear connector mounting means projecting upwardly from said upper surface of said at least one girder, and a shear connector mounted to said shear connector mounting means and projecting upwardly therefrom, said shear connector having an upper portion thereof extending through an opening defined in said continuous deck means so that said upper portion of said shear connector is adapted to be embedded in said poured concrete on said deck means.
Claim 2
Dependent Claim
170 words
A framed concrete slab structure comprising at least one girder having an upper surface, at least one joist intersecting said at least one girder along the upper surface of said at least one girder, said at least one joist being supported by the upper surface of said at least one girder, and continuous deck means disposed to rest on said joist spaced above said girder by said joist and adapted to receive poured concrete thereon, shear connector mounting means mounted on said upper surface of said at least one girder and spaced away and separate from said joist, said shear connector mounting means projecting upwardly from said upper surface of said at least one girder, and a shear connector mounted to said shear connector mounting means and projecting upwardly therefrom, said shear connector having an upper portion thereof extending through an opening defined in said continuous deck means so that said upper portion of said shear connector is adapted to be embedded in said poured concrete on said deck means.
Claim 3
Dependent Claim
34 words
A framed concrete slab structure according to claim 1 wherein each rigid shear connector mounting means has a length shorter than the distance between joists and is provided with a plurality of shear connectors.
Claim 4
Dependent Claim
48 words
A framed concrete slab structure according to claim 1 wherein said shear connector mounting means is of T-shaped vertical cross-section having its stem welded to the upper surface of the at least one girder and the shear connectors being welded on the top of the T-shaped mounting means.
Claim 5
Dependent Claim
49 words
A framed concrete slab structure according to claim 1 wherein said shear connector mounting means is of inverted C-shaped vertical cross-section, having its lower edges welded to the upper surface of the at least one girder and the shear connectors being welded on top of the C-shaped mounting means.
Claim 6
Dependent Claim
51 words
A framed concrete slab structure according to claim 1 wherein said shear connector mounting means is of inverted L-shaped vertical cross-section, having its lower edges welded to the upper surface of at least one girder and the shear connectors being welded on the upward directed vertex of the L-shaped mounting means.
Claim 7
Dependent Claim
20 words
The structure as claimed in claim 1 wherein said shear connector mounting means are laterally spaced away from said joist.
Claim 8
Dependent Claim
23 words
A framed concrete slab structure according to claim 1 wherein a rigid shear connector mounting means is located in each space between joists.
Claim 9
Dependent Claim
155 words
A framed concrete slab structure comprising at least one girder having an upper surface, at least one joist intersecting said at least one girder along the upper surface of said at least one girder, said at least one joist being supported by the upper surface of said at least one girder, and continuous deck means disposed to rest on said joist spaced above said girder by said joist and adapted to receive poured concrete thereon, shear connector means mounted on said upper surface of said at least one girder and projecting upwardly therefrom, said shear connector means being spaced away and separate from said joist on said upper surface of said girder, said shear connector means having a portion extending through at least one opening provided in said continuous deck means, said portion of said shear connector means extending through said opening being adapted to become embedded in said poured concrete on said deck means.
Claim 10
Dependent Claim
155 words
A framed concrete slab structure comprising at least one girder having an upper surface, at least one joist intersecting said at least one girder along the upper surface of said at least one girder, said at least one joist being supported by the upper surface of said at least one girder, and continuous deck means disposed to rest on said joist spaced above said girder by said joist and adapted to receive poured concrete thereon, shear connector means mounted on said upper surface of said at least one girder and projecting upwardly therefrom, said shear connector means being spaced away and separate from said joist on said upper surface of said girder, said shear connector means having a portion extending through at least one opening provided in said continuous deck means, said portion of said shear connector means extending through said opening being adapted to become embedded in said poured concrete on said deck means.
Claim 11
Dependent Claim
19 words
The structure as claimed in claim 8 wherein said shear connector means are laterally spaced away from said joist.
Claim 12
Dependent Claim
25 words
A framed concrete slab structure according to claim 8 wherein said shear connector means includes at least two different sections having different cross sectional dimensions.
Claim 13
Dependent Claim
53 words
A framed concrete slab structure according to claim 10 wherein a first lower section of said shear connector means has a cross section larger than said opening in said deck means and a second upper section of said shear connector means has a cross section smaller than said opening in said deck means.
