Abstract

This invention relates to the provision of mechanical anchorage in composite steel and concrete structural members such as slabs and beams, and more particularly to anchors adaptable as end anchors, to decking panels fitted with end anchors, and to composite structural members incorporating concrete slabs on such decking panels. According to a first aspect, the invention provides an anchor for composite steel and concrete structural members including an element of substantially rigid sheet material defining a base portion and at least two flange portions upstanding from the base portion, which element is a length to fit across a pan of a ribbed metal sheet with the flange portion extending across said pan, and means on or co-operable with the base portion engageable with complementary holes in the metal sheet so to extend through said holes, said means being adapted for holding the element in the metal sheet. The element preferably incorporates an integral channel which defines said base portion and a pair of said upstanding flange portions disposed at opposite edges of the base portion. The aforesaid means preferably includes plural stud elements of annular cross-section disposed for extending through said holes in the metal sheet. Such stud elements may be dimensioned to project integrally from a common backing plate through said holes in the metal sheet and registering apertures in said base portion.
