ENVIRONMENT-FRIENDLY BIDIRECTIONAL HOLLOW SLAB SYSTEM AND THE CONSTRUCTION METHOD THEREOF CAPABLE OF REDUCING THE QUANTITY OF CONCRETE OF A SLAB USING A HOLLOW FORMATION BODY

摘要

PURPOSE: An environment-friendly bidirectional hollow slab system is provided to reduce the weight of a slab and to have improved structural performance compared with the existing solid slab under the design load, to have similar structural performance under the ultimate load and to decrease noise and vibration. ;CONSTITUTION: An environment-friendly bidirectional hollow slab system contains a first reinforcing bar(11), a hollow formation body(20) installed to one side of the first reinforcing bar and provided with a hollow on the inner part, a second reinforcing bar(12) installed to the opposite side of the first reinforcing bar, a cage member keeping the hollow formation bodies at the preset interval and coupling the hollow formation bodies to form a module, and a concrete layer(40) laying the first reinforcing bar, the module and the second reinforcing bar.;COPYRIGHT KIPO 2011
