Abstract
A horizontal floor or roof structure having a plurality of spaced parallel joists each joist having a vertical web with upper and lower flanges extending from the web. Each flange has a free edge with a tubular bead extending along each free edge and having an elliptical cross-section wherein the minor axis is at least 20% of the major axis. A floor or roof member is supported over said metal joist. A preferred method of forming a horizontal reinforced concrete wall structure for a building includes mounting a wire mesh material over the upper flanges of the joists, and pouring concrete in a flowing condition onto the concrete forms over the mesh material and over the upper flanges of the joists so that curing of the concrete provides a horizontal reinforced composite concrete wall structure.
Claims7
A horizontal concrete wall structure for a building comprising:
- a plurality of spaced parallel metal joists supported at opposed ends thereof, each metal joist having a vertical web with upper and lower flanges extending outwardly therefrom, each lower flange having a free edge and a tubular bead extending along the free edge having an elliptical cross-section wherein the minor axis is at least 20% of the major axis, each lower flange being bowed and forming a trough between the bead and web of each joist;
- a wire mesh reinforcing material mounted adjacent the upper flanges of said metal joists;
- and
- concrete surrounding the upper flanges of said metal joists and said wire mesh reinforcing material to form the horizontal concrete wall structure.
A horizontal wall structure for a building comprising:
- a plurality of spaced parallel integral metal joists each having a vertical web with upper and lower flanges extending from the web, the lower flange having a free edge and a tubular bead extending along the free edge with each bead having an elliptical cross-section wherein the minor axis is at least 20% of the major axis, said lower flange being bowed and forming an upwardly opening trough between the bead and web of each joist;
- and
- at least one wall member secured onto said metal joists.
A horizontal wall structure for a building comprising:
- a plurality of spaced parallel integral metal joists each having a vertical web with upper and lower flanges extending from the web, the lower flange having a free edge and a tubular bead extending along the free edge with each bead having an elliptical cross-section wherein the minor axis is at least 20% of the major axis;
- at least one wall member secured onto said metal joists, said wall member including at least one upper layer and a lower plywood layer secured to said upper layer;
- and
- fasteners securing said joists to said wall member.
