Claim 9

A building assembly comprising: a beam having a generally flat surface and a bolt-receiving opening therethrough; a building slab having a pair of opposed faces and an outer periphery having a number of spaced recesses, the slab being positionable with one of said faces in engagement with the surface of the beam and with at least one recess adjacent to said surface; and fastening means carried by the slab at each recess, respectively, for interconnecting the slab and the beam, said fastening means including an angle member having a first section rigidly secured to the slab and a second section integral with the first section and extending laterally therefrom, said second section being disposed substantially flush with said one face and having a hole therethrough alignable with said opening of the beam, an angle element having a pair of opposed sides with each side having an outer marginal edge, the marginal edges of said sides being rigidly secured to said first section, said sides defining a space aligned with said hole in the second section, each of said sides having a side marginal edge, and a plate spanning the side marginal eDges of said sides for use in clamping said slab to the beam when a bolt extends through the opening, the hole and the space and when a nut is threaded onto the bolt.

Claim 10

A building assembly comprising: a beam having a generally flat surface and a bolt-receiving opening therethrough; a building slab having a pair of opposed faces and an outer periphery having a number of spaced recesses, the slab being positionable with one of said faces in engagement with the surface of the beam and with at least one recess adjacent to said surface; and fastening means carried by the slab at each recess, respectively, for interconnecting the slab and the beam, said fastening means including an angle member having a first section rigidly secured to the slab and a second section integral with the first section and extending laterally therefrom, said second section being disposed substantially flush with said one face and having a hole therethrough alignable with said opening of the beam, an angle element having a pair of opposed sides with each side having an outer marginal edge, the marginal edges of said sides being rigidly secured to said first section, said sides defining a space aligned with said hole in the second section, each of said sides having a side marginal edge, and a plate spanning the side marginal eDges of said sides for use in clamping said slab to the beam when a bolt extends through the opening, the hole and the space and when a nut is threaded onto the bolt.

Claim 11

A building unit comprising: a concrete slab having a pair of opposed faces and an outer periphery provided with a number of spaced recesses extending into the slab; and fastening means in each recess respectively, said means including an angle member having a first section rigidly secured to the slab and a second section provided with an opening therethrough for receiving a fastening device, and an angle element having a pair of sides with each side having an outermost marginal edge, the marginal edge of said sides being rigidly secured to the first section to present a space between said sides and aligned with the opening in the second section whereby the slab can be coupled to a supporting framework by the device, the second section being adjacent to one of the faces.

Claim 12

A building unit comprising: a concrete slab having a pair of opposed faces and an outer periphery provided with a number of spaced recesses extending into the slab; and fastening means in each recess respectively, said means including an angle member having a first section rigidly secured to the slab and a second section provided with an opening therethrough for receiving a fastening device, and an angle element having a pair of sides with each side having an outermost marginal edge, the marginal edge of said sides being rigidly secured to the first section to present a space between said sides and aligned with the opening in the second section whereby the slab can be coupled to a supporting framework by the device, the second section being adjacent to one of the faces.
