SHEAR FORCE REINFORCING APPARATUS OF CONCRETE FILLED STEEL TUBE COLUMN-REINFORCED CONCRETE FLAT SLAB JOINT

摘要

PURPOSE: A shear reinforcing device for a reinforced concrete flat slab and a joint of a concrete filled steel pipe column is provided to effectively reinforcing shear failure generated in reinforced concrete flat slab. CONSTITUTION: A shear reinforcing device is composed as follows. A reinforcing band(10) is coupled with the outer surface of a concrete filled steel pipe column(C). Reinforcing fixtures(15) are coupled to the outer surface of the reinforcing band in two rows. Fixing rings(20) connect the reinforcing fixtures, and form an interval between the fixing rings and the reinforcing band. Hooks(31) are formed in the end of C-shaped reinforcing bars(30). The C-shaped reinforcing bars connect the reinforcing band and the fixing rings. Saddles(40) are installed in a longitudinal direction of the reinforcing bars.
