MONO CELL TYPE FLEXIBLE CONNECTING DEVICE EASY TO CHANGING OF INTEGRAL MONO CELL THE AND ITS INSTALL AND CHANGING METHOD

摘要

The present invention relates to a mono-cell type expansion joint apparatus which enables integral mono-cells to be easily replaced and installation and replacement methods thereof. More specifically, the mono-cell type expansion joint apparatus can be easily installed on a joint of a bridge and enable integral mono-cells to be replaced without conducting a complex operation when the mono-cell type expansion joint apparatus is aged. The present invention can enable the aged integral mono-cells to be replaced by coupling a pair of mono-cell settling holders and the aged integral mono-cells after inserting the aged integral mono-cells to the mono-cell settling holder pair fixed to face spaced concrete units.
