Floor system

Claim 1

A floor system for fabricating a poured-in-place concrete floor of a building having walls between which the floor system extends, comprising, a plurality of metal joists spaced from each other and spanning between the walls of the building in side-by-side relationship to each other, a plurality of bracing means of elongated metal construction each extending between adjacently spaced joists, each joist having spaced means for receiving the bracing means to support the bracing means at a lower elevation than the top surface of the joist, metal decking means comprising individual metal decking strips extending between adjacent joists and resting on the spaced bracing means, each said bracing means comprising a bracing channel having a length corresponding substantially to the spacing between joists and extending transversely between joists, said spaced means for receiving including spaced holes each for receiving two bracing channels extending in opposite directions from the joist, each said bracing channel having means defining slots thereacross at both ends for receiving an edge defining the hole for locking the channel to the joist against longitudinal movement relative to the joist, and a rigid wedge removably received by the hole between adjacent ends of oppositely directed bracing channels for forcing the slots of the channel into engagement with opposite edges defining the hole so as to fix the relative position between said adjacent ends, said rigid wedge being separable from the channels and being engageable with the channels after the channels are in position in the hole.
