Metal structure frame used for industrial assembly type movable environment-friendly toilet

The invention provides a metal structure frame used for an industrial assembly type movable environment-friendly toilet. The metal structure frame is formed by assembling and connecting standard section combined section columns (I) with C-shaped cold bend curled edge thin wall type steel beams (II). By adopting unit bodies of the same type, the combined section columns are combined into two kinds of standard section columns according to different combination modes. The unit bodies are C-shaped cold bend curled edge thin wall type steel. All the unit bodies are entirely provided with bolt holes. The length of the steel beams (II) conforms to the construction modular system. The sections of all the steel beams are consistent in height. The steel beams (II) are connected with the combined section columns (I) through five kinds of standard beam column connecting joints. The steel beams are connected with one another through standard beam beam connecting joints. The two kinds of standard section columns comprise t
