Problems solved by technology

In actual work, it is sometimes encountered that the edge of a certain part of the building is temporarily changed (such as the temporary change of the gutter at the edge of the roof during construction), which will lead to the gap between the protruding edge and the jacking sleeve of the tower crane and the tower crane. The main girder of the balance arm interferes, and the tower crane is blocked when it descends and cannot descend

Embodiment Construction

[0008] The inventor has applied the method of the present invention to a complex residential building. During the construction period of this building, a Jianglu brand QT125 tower crane was used. When the decoration of the main body and the upper part of the building is basically completed, the tower crane needs to be lowered and dismantled. At that time, it was found that the gutter at the edge of the roof of the building, due to temporary changes during construction, interfered with the protruding edge of the roof gutter with the jacking sleeve of the tower crane and the main girder of the balance arm of the tower crane. The vertical height of the outer edge of the ditch is 0.8m, and the interference depth is about 0.7m. The blocked components on the tower crane are the main girder of the balance arm with a length of 14m in the horizontal direction and a jacking sleeve with a height of more than 6m in the vertical direction. When using the method of the present invention, at ...

Abstract

The invention discloses a tower crane descending method which is used for ensuring the normal descending of the components of the upper part of the tower crane when interfered by buildings; the method is characterized in that: one or two attached supports at the upper part of the disassembly crane tower enable the tower body to suspend out; then use a jack to get the tower body inclined so that blocked components can leave the interference position and then descend the tower crane. The descending method has the advantages that the method is applicable for any type of tower cranes when blocked by buildings during the descending process; in particular when the interference size is not so large, the method is very simple and efficient.

Description

technical field [0001] The invention relates to a method for lowering a tower crane. Background technique [0002] The tower mast of the tower crane, the main body of the tower is made of standard joints, and its size is consistent. In actual work, it is sometimes encountered that the edge of a certain part of the building is temporarily changed (such as the temporary change of the gutter at the edge of the roof during construction), which will lead to the gap between the protruding edge and the jacking sleeve of the tower crane and the tower crane. The main girder of the balance arm interferes, and the tower crane is blocked when it descends and cannot descend. Contents of the invention [0003] The object of the present invention is to provide a tower crane lowering method for the normal drop of the upper part of the building interference tower crane, so that the tower crane can still be lifted when the jacking sleeve frame and the rotating tower body of the tower crane...
