Abstract

The invention discloses a construction method of a ground jacking type tower crane, which is arranged outside a building and comprises a frame body, a jacking bracket, a standard section, a transport vehicle, a locking device and a jack; It is connected to the building, including a fixed frame body and a lifting frame body. The fixed frame body is fixed on the ground and is located at the lower part of the lifting frame body. The lifting frame body is arranged in the lifting frame body and moves up and down. The jack passes through The jacking bracket is arranged under the lifting frame body, the locking device is arranged on the fixing frame body and the wall-attaching bracket, the inner side is connected with the lifting frame body, the transport vehicle is arranged on the track, and the inner end of the track is located on the fixing frame Inside the body, the standard section is transported by a transporter. On the premise that the original standard section of the tower crane is not changed, the invention replaces the lifting method of using an external hanger on the upper part of the tower crane, realizes the lifting operation of the tower crane on the ground and inside, and avoids the risks brought by high-altitude operation.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a ground-lifting tower crane. Background technique [0002] With the shortage of urban land resources, high-rise buildings are becoming more and more common, and the overall height is mainly 99 meters. In the construction of existing buildings below 100 meters, the tower cranes generally used are mainly attached tower cranes. However, the jacking method of the externally attached external tower crane is mostly lifted by the external pylon on the upper part of the tower crane. This construction method requires manual high-altitude work, which has certain risks. The present invention provides a construction method for a ground-lifting tower crane to overcome the above-mentioned defects. SUMMARY OF THE INVENTION [0003] The invention provides a construction method of a ground jacking tower crane, which realizes the jacking operation of the...
