Construction platform for steel structure bridge installation

The invention discloses a construction platform for steel structure bridge installation, the construction platform is hung on the lateral lower part of each section of steel box girder of the steel structure bridge through a connecting frame pipe, and the top end of the connecting frame pipe is provided with a clamping mechanism; the clamping mechanism comprises an upper clamping plate which is rigidly connected with the connecting frame pipe and a lower clamping plate which is movably connected with the upper clamping plate through a bolt; the connecting frame pipe is clamped on a protruding edge horizontally arranged at the bottom end of a transverse partition plate on the steel box girder through the clamping mechanism. and an asbestosed wire gauze is arranged on the top surface of the construction platform. According to the construction platform, a sufficient operation space environment with a fireproof function is provided for constructors, and the problem that partition plates between adjacent steel box
