Standard section connection structure for tower crane

The utility model discloses a novel standard section connection structure for a tower crane. A thick steel plate is welded on the outer side of a bolt sleeve post of a tower crane standard section; contact surfaces can correspond one by one and can be compressed with each other when the standard sections are connected; a symmetrical structure is formed by the contact surfaces as the center; and the side end surface and the contact surface of the steel plate are subjected to bright color design. According to the structure disclosed by the utility model, stress on the connection part generated by the standard sections caused by bending moment can be absorbed; the probability of fatigue damage or a crack generated by the bolt is lowered; the reliability of the standard section connection structure is improved; the overall balance and the overall safety of the tower crane are improved; the problems such as loosening and dislocation can be found out in advance and can be timely processed by the added bright color design surface, so that the safety of staff is further ensured.
