Title:
FLOOR AND ROOF STRUCTURES FOR BUILDINGS
Document Type and Number:
WIPO Patent Application WO2002038875
Kind Code:
A3
Abstract:
A horizontal floor, wall or roof structure (10) having a plurality of spaced parallel joists (12),each joist (12) having a vertical web (40) with upper and lower flanges (41, 42) extending from the web (40). Each flange (41, 42) has a free edge with a tubular bead (44, 46) 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, wall or roof member (18) is supported over the metal joist (12). A preferred method of forming a horizontal reinforced concrete floor, wall or roof structure (10) for a building includes mounting a wire mesh material (16) over the upper flanges (41) of the joists (12), and pouring concrete (18) in a flowing condition onto the concrete forms (14) over the mesh material (16) and over the upper flanges (41) of the joists so that curing of the concrete (18) provides a horizontal reinforced composite concrete wall structure (10).
