DEVICE TO MEASURE CARBONATION DEPTH FOR SAFETY DIAGNOSIS OF FERROCONCRETE STRUCTURE USING CORE TEST PIECE

摘要

The present invention relates to a device to measure a carbonation depth to diagnose safety of a ferroconcrete structure using a core test piece capable of facilitating a cleaning work of a core test piece collected from the ferroconcrete structure. The device comprises: a pair of horizontal channels (30, 32) installed horizontally in an axial direction of a core test piece (20) at a distance from each other; leg units (30a, 30b, 32a, 32b) which are downwardly bent towards a floor (22) from an outer side of the horizontal channels (30, 32); footholds (34, 36) installed in a lower part of the leg units (30a, 30b, 32a, 32b) and supported on the floor (22); fixing brackets (40, 42) installed in an upper part of the horizontal channels (30, 32) at a distance from each other; radial support rollers (43, 44, 45, 46) installed in the fixing brackets (40, 42), supporting the core test piece (20); a plurality of horizontal links (51, 52, 53, 54) installed inside the horizontal channels (30, 32); an elevation bracket (50) installed on top of the horizontal links (51, 52, 53, 54); axial guide rollers (55, 56, 57) installed in an elevation bracket (50), guiding the core test piece (20) in the axial direction; and a lever (58) installed in the elevation bracket (50).;COPYRIGHT KIPO 2016
