BEAM HAVING A WEIGHT REDUCTION UNIT FOR REDUCING A WEIGHT CAPABLE OF REDUCING THE GENERATION OF CARBON DIOXIDE

摘要

PURPOSE: A beam having a weight reduction unit for reducing a weight is provided to reduce the weight of the beam by reducing the quantity of concrete used for the beam.;CONSTITUTION: A beam having a weight reduction unit for reducing a weight comprises a concrete body, weight reduction units(100), and reinforcing bars. The weight reduction units comprise lightweight bodies(60). The lightweight bodies are buried in the concrete body in a longitudinal direction and have a smaller weight than concrete. The reinforcing bars resist tensile stress and/or shearing stress applied to the concrete body.;COPYRIGHT KIPO 2012
