DETACHABLE STRESS REINFORCEMENT DEVICE AND A PC(Prestressed Concrete) STRUCTURE CONSTRUCTION METHOD USING THE SAME

摘要

PURPOSE: A detachable stress reinforcement device and a PC structure construction method using the same are provided to prevent the shear force and the eccentricity of PC columns, PC beams, or composite beams by using stress reinforcement devices.;CONSTITUTION: A detachable stress reinforcement device(100) comprises a main body(130) and a length adjusting unit(150). A contact unit(140) is installed in the main body and female threads are formed in the main body. The length adjusting unit is coupled with the main body and the contact unit is installed in the length adjusting unit. The stress reinforcement device is installed between the unit members of each layer while lifting a PC column for preventing the buckling and the deformation due to weight load. The bending of the PC column is prevented by installing the PC beam or a composite beam after the installation of the PC column.;COPYRIGHT KIPO 2013
