Roll Form Products, Inc. - Boston MA
International Classification:
E04C 232, E04C 503
US Classification:
428599
Abstract:
A corrugated metal decking having alternating crests and troughs and a decking web disposed angularly out of the vertical, a plurality of linear indentations each extending across the decking web in a direction between the crest and trough walls, said indentations being disposed in a parallel array, the length of each indentation being less than the full width of the decking web but extending over a substantial major fraction of the web width, said indentations being provided in contiguous alternating inner and outer formed indentations substantially symmetrical about the web plane, the length of each indentation being in the range of 70% to 95% of the web width, said web being joined to the crest and trough walls by a radius bend, the indentation length being on the order of but less than the dimension a-2R, where a is the web width and R is the radius of the bend and said indentations do not extend into crest walls, trough walls or radius bends.

US Patent:

Filed:

Appl. No.:
6/816395
Inventors:
Konstantinos I. Karoubas - Hull MA
Assignee:
Roll Form Products, Inc. - Boston MA
International Classification:
E04C 232, E04C 503
US Classification:
428599
Abstract:
A corrugated metal decking having alternating crests and troughs and interconnecting therebetween a decking web that is characterized by improved stiffening means, in particular in the form of embossments or indentations. There are provided a plurality of linear indentations, each extending across the decking web between the crest and trough walls. These indentations include inner and outer formed indentations, formed symmetrically about the web center plane with the length of each indentation being in the range of 70%-90% of the web cross-dimension and with the indentations being closely spaced. This arrangement provides for superior web stiffening and also provides improved composite action for interlocking between the metal decking and the concrete.
