Abstract

The invention discloses a ground jacking type tower crane device and a construction method. The ground jacking type tower crane device is arranged outside a building and comprises a frame body, a jacking support, a standard knot, a transport vehicle, a locking device and a jack, the frame body is connected to a building through a wall-attached support and comprises a fixing frame body and a lifting frame body, the fixing frame body is fixed to the ground and located on the lower portion of the lifting frame body, the lifting frame body is arranged in the lifting frame body and moves up and down, the jack is arranged below the lifting frame body through the jacking support, the locking device is arranged on the fixing frame body and the wall-attached support, the inner side of the locking device is connected with the lifting frame body, the transport vehicle is arranged on a rail, the inner end of the rail is located in the fixing frame body, and the standard knot is transported throughthe transport vehicle. On the premise that an original standard knot of a tower crane is not changed, the jacking mode that an external hanging frame is adopted on the upper portion of the tower crane is replaced, jacking operation of the tower crane on the ground and inside the tower crane is achieved, and risks caused by high-altitude operation are avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a ground jacking tower crane device and a construction method. 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. During the construction of existing buildings below 100 meters, the tower cranes generally used are mainly external tower cranes. However, the jacking method of the externally attached external tower crane is usually lifted by the external hanger on the upper part of the tower crane. This construction method requires manual high-altitude operations, which has certain risks. The invention provides a ground jacking type tower crane device and a construction method to overcome the above defects. Contents of the invention [0003] The invention provides a ground jacking type tower crane device and a construction method, which realize t...
