Tooling die of steel structure platform supports

The invention relates to the field of manufacturing of a steel structure platform, in particular to a tooling die of steel structure platform supports, such as platform frames, air platforms, cargo platforms, wharf channels, ship decks, underground mine well supports, lifting vehicle space trays, modularized floor slabs and the like. The tooling die comprises a main vertical column positioning device, an inclined support positioning device and a positioning and supporting mechanism, wherein the main vertical column positioning device is used for fixing a main vertical column of the steel structure platform support, and the positioning and supporting mechanism is used for supporting the lower part of the steel structure platform. The tooling die has the advantages that the production efficiency of the steel structure platform support can be improved; the tooling die of the steel structure platform support is suitable for producing and manufacturing various shapes and types of steel structure platform supports
