Profiled Metal Sheet

Abstract

A profiled metal sheet for use in the construction of composite slabs is disclosed. The sheet includes a plurality of parallel longitudinal ribs separated by pans and male and female members at opposite sides of the sheet that enable adjacent sheets to be connected together in overlapping relationship. At least one of the ribs, male members and female members has a side that extends from the pan that is adjacent the rib or the member. The side includes a re-entrant section and a corner section that connects the side and the adjacent pan. The corner section includes a plurality of regions at spaced intervals along the length of the corner section that extend outwardly compared with adjacent regions of the corner section. The spaced regions are provided to improve longitudinal slip resistance of composite slabs formed from the sheet.

         16 . A profiled metal sheet of substantially uniform thickness for use in construction of composite slabs comprising:
 a plurality of parallel longitudinal ribs separated by pans, and male members and female members at opposite sides of the sheet that enable adjacent sheets to be connected together in overlapping relation, at least one of the ribs having a uniform transverse cross-section along its length and comprising a top flange and two sides, each side including a first planar section that extends outwardly and downwardly from the top flange, a second planar section that extends downwardly and inwardly from a lower edge of the first planar section distal the top flange and forms a re-entrant section, and a third planar section that extends downwardly and outwardly from a lower edge of the second planar section and connects the side to the adjacent pan and forms a corner section with the pan, the corner section including a plurality of regions at spaced intervals of less than 95 mm along the length of the corner section that extend outwardly compared with adjacent regions of the corner section, with the spaced regions being provided to improve longitudinal slip resistance of composite slabs formed from the sheet.
