Efficient large electrical module container supporting frame building structure

The utility model discloses an efficient large electrical module container supporting frame building structure which comprises a welding bottom plate and a plurality of positioning blocks. A plurality of positioning block installation grooves are transversely and longitudinally formed in the welding bottom plate. The positioning blocks are arranged on the welding bottom plate. The contour formed by the positioning blocks is consistent with the outer contour formed by a supporting frame to be welded, and the positioning blocks are fixed to the installation grooves at corresponding positions. The efficient large electrical module container supporting frame building structure has the advantages that steel girders are placed by automatically adjusting the positions and angles of the positions, provided with the positioning blocks, of a welding floor according to the structure of the steel girders, and therefore the steel girders can be accurately positioned, finally all the steel girders are connected through welding, and the efficient large electrical module container supporting frame building is achieved.
