1. A sleeve device for transferring bending moments induced in a reinforced concrete slab, said sleeve device comprising:
a generally hollow member positioned on and fastened to a bottom formwork defining said reinforced concrete slab, said generally hollow member configured to create a void in said reinforced concrete slab by pouring of concrete around an outer wall of said generally hollow member, said generally hollow member further configured to transfer compressive stresses across a bottom of said generally hollow member and tensile stresses through tension rebars and an upper portion of said generally hollow member; and said tension rebars connected to opposing sides of said upper portion of said generally hollow member, said tension rebars are configured to be spliced with top rebars of said reinforced concrete slab in accordance with a rebar tension splice length for transferring said bending moments induced in said reinforced concrete slab, wherein said bending moments in said reinforced concrete slab are resisted by said tensile stresses in said tension rebars and said compressive stresses in said concrete, and wherein said tensile stresses in said tension rebars on said opposing sides of said generally hollow member are transferred into said generally hollow member, and said tensile stresses acting on said opposing sides of said generally hollow member are balanced out through said outer wall of said generally hollow member, thereby bridging said tensile stresses from said tension rebars. |
