Rebar expansion simulated loading test apparatus and a loading test method

摘要

PROBLEM TO BE SOLVED: To provide a reinforcement expansion simulation and load test device and reinforcement expansion simulation and load test method for easily, accurately, and empirically grasping a phenomenon that the influence of the reinforcement corrosion expansion of a reinforced concrete structure on an interior or surface of the concrete causes peeling or flaking.;SOLUTION: A spacer 4 which adjusts expansion sections 2 each to be located at a position at which reinforcement corrosion expansion is to be simulated, and a guide section 3 in which a hole is formed such that a tip end of an indentation section 1 can be inserted into the hole, a plurality of wedged expansion sections 2, and the indentation section 1 having a pyramidal tip end are inserted into a reinforced concrete test piece 5 in which a cylindrical hole is formed such that the indentation section 1, the expansion sections 2, and the guide section 3 can be inserted into the cylindrical hole and outer peripheries thereof can contact to one another. A reinforcement expansion simulation and load test device further includes: a loading device 7 indenting the indentation section 1; a load gauge 8 measuring an indentation load while the indentation section 1 is indented; and a vertical displacement gauge 9 measuring an indentation amount.;COPYRIGHT: (C)2015,JPO&INPIT
