PURPOSE: A footstool connection structure for checking a bridge is provided to easily connect and separate the footstools and to easily join the footstools by fit-joining, thereby improving the constructability and work efficiency. CONSTITUTION: A footstool connection structure for checking a bridge comprises an L-shaped first connection unit(210) and a reverse L-shaped second connection unit(310). At least one of the first and second connection units is formed respectively corresponding to the bending units(21,31) and an exterior surface of the footstools(20,30). Fitting groove units(211,311) and fitting protrusion unit(212,312) are fit-joined so that the footstools are connected. |
