Abstract

A safety check-up apparatus for a steel box slab section of a bridge is provided to measure subsidence of a bridge slab by causing antifreezing solution to rise in a transparent window as rollers of elastic rollers press a tube filled with the antifreezing solution. A safety check-up apparatus for a steel box slab section of a bridge comprises a support plate(10), front and rear operating frames(20,20a), front and rear check-up bars(30,30a), and front and rear elastic rollers(40,40a). The front and rear operating frames are installed on the support plate in an X shape. The top parts of the front and rear operating frames closely contact the bottom of a bridge slab through elasticity of the frost and rear elastic rollers. The front and rear check-up bars are installed at the front and rear operating frames and show downward movement of the front and rear operating frames visually. When a bridge slab subsides, rollers of the front and rear elastic rollers press antifreezing solution-filled tubes installed in slide elongated holes of the front and rear operating frames. At this moment, the antifreezing solution moves to transparent windows of the front and rear check-up bars. As level of the antifreezing solution rises, a gauge marks the level of the antifreezing solution.
