Abstract

The utility model discloses a steel platform system suitable for a super high-rise high-altitude large-span cantilever structure formwork. The system comprises a steel platform body, a plurality of pull rods and a plurality of supporting rods. The steel platform body comprises a plurality of cantilever steel beams which are uniformly distributed in rows and a plurality of connecting rods; every two adjacent cantilever steel beams are fixedly connected through at least two connecting rods. Each cantilever steel beam comprises a steel beam main body section, a slope section and a fixed section which are integrally connected in sequence; the steel beam main body section and the fixed section are horizontal sections, and the slope section inclines downwards by a preset angle relative to the steel beam main body section; the end, away from the slope section, of each fixed section can be fixed to a building wall. The lower ends of the pull rods are hinged to the upper surface of the steel beam main body section, and the upper ends can be fixed to a building wall; the upper ends of the supporting rods are hinged to the lower surface of the steel beam body section, and the lower ends can be fixed to a building wall. According to the system, the reliability of the steel platform system is improved, convenient disassembly and assembly can be achieved, the construction efficiency is improved, and the construction safety is effectively guaranteed.
