Abstract
Abstract A profiled castellated metal sheet has secondary features 4 surmounting its flat-topped areas 3 which run parallel to the castellations and which are upstanding from the flat-topped areas 3 in use and have a maximum open width of 25 mm. These secondary features 4 are used to support a mesh when the sheet is used as a decking for a composite steel/concrete floor, and avoid the need to support the mesh on separately provided mesh support stools. The use of such a castellated sheet therefore decreases both the time and cost involved in construction of such composite floors, and also increases the structural integrity of the floors so formed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
51 words
A castellated profiled metal sheet having flat-topped areas (3), characterised in that secondary features (4) are formed in the flat-topped areas (3) of the sheet, which features (4) run parallel to the castellations, are upstanding from the flat-topped areas (3) in use and have a maximum open width of 25 mm.
Claim 2
Dependent Claim
51 words
A castellated profiled metal sheet having flat-topped areas (3), characterised in that secondary features (4) are formed in the flat-topped areas (3) of the sheet, which features (4) run parallel to the castellations, are upstanding from the flat-topped areas (3) in use and have a maximum open width of 25 mm.
Claim 3
Dependent Claim
20 words
A sheet according to claim 1, characterised in that the secondary features (4) are substantially of dovetail shape in section.
Claim 4
Dependent Claim
30 words
A sheet according to claim 2, characterised in that the dovetail shaped secondary features (4) have a width which increases in dependence on the distance from the flat-topped areas (3).
Claim 5
Dependent Claim
20 words
A sheet according to claim 1, characterised in that the secondary features (4) are substantially of inverted-U shape in section.
Claim 6
Dependent Claim
20 words
A sheet according to claim 1, characterised in that the secondary features (4) are substantially of inverted-V shape in section.
Claim 7
Dependent Claim
23 words
A sheet according to any preceding claim, characterised in that the height of the secondary features (4) is between 13 and 31 mm.
Claim 8
Dependent Claim
41 words
A sheet according to any preceding claim, characterised in that the secondary features (4) are open-bottomed where they join the flat-topped areas and the openings at their bottoms have a constant width along their lengths of not more than 25 mm.
Claim 9
Dependent Claim
15 words
A sheet according to any preceding claim, wherein the sheet has a generally trapezoidal profile.
Claim 10
Dependent Claim
68 words
A composite concrete/metal floor wherein a castellated profiled metal sheet having flat-topped areas (3) is used to support a reinforcement mesh which is embedded in concrete, characterised in that secondary features (4) are formed in the flat-topped areas (3) of the sheet, which features (4) run parallel to the castellations, are upstanding from the flat-topped areas (3) in use and have a maximum open width of 25 mm.
Claim 11
Dependent Claim
68 words
A composite concrete/metal floor wherein a castellated profiled metal sheet having flat-topped areas (3) is used to support a reinforcement mesh which is embedded in concrete, characterised in that secondary features (4) are formed in the flat-topped areas (3) of the sheet, which features (4) run parallel to the castellations, are upstanding from the flat-topped areas (3) in use and have a maximum open width of 25 mm.
