Embodiment 1
[0025] A 50t casting bridge crane is installed in the well tower with a track elevation of 73.5m. The well tower is divided into seven floors. The bridge crane is installed on the track on the seventh floor of the tower top. The net height of the first to sixth floors is 10 meters, the seventh floor is 13 meters, the floor elevation of the seventh floor is 65 meters, the track surface elevation is 73.5 meters, and the roof elevation is 78 meters. The weight of the 50t casting bridge crane is 41.6t. The heaviest single part of the main girder on the side of the electrical room is 13t. The maximum volume is length x width x height = 14.1mx3.2mx1.5m. There is a 4.8mx3.5m in the middle of each floor in the well tower The hoisting hole of the trolley, the length x width of the trolley = 4mx4m.
[0026] 1. Review of the bearing capacity of the roof beam of the well tower: the heaviest single piece to be hoisted is the transmission side box girder, with a total weight of 13t. The be...

The invention provides a construction method for hoisting a bridge type crane in a high-rise well tower type building and belongs to the field of a mounting technology of the bridge type crane in the high-rise well tower type building. The method comprises the following steps of: rechecking well tower roof beam bearing force; setting hoisting points on a roof beam; determining a winding pulley system and a steel wire rope; arranging the winding pulley system; selecting hoisting points of a box beam and a main trolley; conveying and hoisting main and secondary box beams and an end beam of the bridge type crane into a mounting rail from a well tower gate; assembling a crane bridge rack and moving a bridge rack jigger away from a hoisting hole; and hoisting a trolley and hoisting other parts, so that just a plurality of several steps can be completed to achieve the aim of construction and installation. The construction method disclosed by the invention has the advantages of being more economical and more time-saving when being compared with the conventional method.
Description
technical field [0001] The invention belongs to the technical field of installation of a bridge crane in a high-rise well-tower-shaped building, and in particular relates to a construction method for hoisting a bridge-type crane in a high-rise well-tower-shaped building. It is especially suitable for hoisting construction projects of large bridge cranes in multi-storey high-rise shaft tower buildings. Background technique [0002] At present, the hoisting of bridge cranes in high-rise shaft tower buildings generally adopts large crawler cranes for hoisting. First of all, this method must be constructed under the condition that the roof beams and roof of the well tower have not been formed, and after the crane is installed, the subsequent construction of roof beams and formwork support of the roof has increased a lot of difficulty, and at the same time, the overall construction progress of the project has also been affected. It will cause a greater impact; secondly, this met...
