ANCHORAGE DEVICE OF FIBER REINFORCED TENDON FOR PRESTRESSED CONCRETE

摘要

PURPOSE: To effectively prevent fracture or dislocation of a fiber reinforced material-made tendon at an anchorage device of the fiber reinforced material- made tendon for prestressed concrete. ;CONSTITUTION: A tendon 4 is held by wedges 1 that can be divided into plural numbers, and the wedges 1 are inserted into a wedge holder 2 to anchor the tendon 4 to constitute an anchorage device of fiber reinforced material made- tendon for prestressed concrete, and a resin coated layer 5 is provided on the surface of retaining grooves 3. Shear force which is applied to the tendon 4 is reduced by the resin coated layer 5, and frictional force to prevent the tendon from being extracted is secured by the layer 5.;COPYRIGHT: (C)1994,JPO&Japio
