Steel structure easy to assemble

The invention discloses a steel structure easy to assemble. The steel structure comprises plane bottom steel, inclined plane steel, supporting steel columns and transverse connecting steel. A plurality of square steel blocks fixedly sleeve the outer surface of the transverse connecting steel in a distribution mode, and the transverse connecting steel is connected with one supporting steel column in a clamped mode through each square steel block. The supporting steel columns are mutually perpendicular to the transverse connecting steel, and a plurality of lower steel column sleeves with the number equal to that of the supporting steel columns are evenly distributed and fixedly connected to the upper surface of the plane bottom steel. According to the steel structure easy to assemble, the plane bottom steel, the inclined plane steel, the supporting steel columns and the transverse connecting steel can be fixedly connected without a welding mode, so that all parts are more convenient to assemble; by arranging a
