Hoisting construction method for fabricated overall framework cast-in-situ core tube structures

Abstract

The invention relates to the technical field of construction of fabricated overall frameworks, and discloses a hoisting construction method for fabricated overall framework cast-in-situ core tube structures. The method includes the following steps that the number and types of tower cranes are determined according to the weights and positions of heaviest prefabricated parts and the preliminary positions of the tower cranes; the final positions of the tower cranes are determined according to an architectural plan, an architectural structure pattern and a cellar structure; performance parametersof the tower cranes are comparatively verified according to the maximum weights of the prefabricated parts and the maximum weight existing in construction; the tower cranes are arranged; and the attachment forms of the tower cranes are determined, wherein according to the attachment forms, the tower cranes are attached to structural columns, the tower cranes are attached to framework beam sides, and the tower cranes are attached to framework beam tops. In the model selection process, the working radius, the maximum hoisting amount of the prefabricated parts, the positions and attachment formsof the tower cranes and the like are combined for overall consideration, and the method has the beneficial effects that the efficiency of the tower cranes is high, and the balance degree between hoisting operation areas is high.

Description

technical field [0001] The invention relates to the technical field of assembly-type integral frame construction, more specifically, it relates to a hoisting construction method for an assembly-type integral frame cast-in-place core tube structure. Background technique [0002] With the advancement of the modernization of the construction industry, traditional construction methods are gradually no longer meeting the development needs of the times, and prefabricated buildings are becoming a new focus of the transformation and development of the construction industry. The installation tasks of medium and large prefabricated components and equipment are increasing day by day, and the application of tower cranes on construction sites is extremely common. Because the tower crane has the advantages of high construction efficiency, wide construction range, and large effective lifting height, it provides great convenience for the construction and installation of prefabricated concre...

Problems solved by technology

[0003] However, the use of tower cranes in the construction process needs to consider the operating radius of the tower crane, the maximum lifting capacity of prefabricated components, and some of the distance between the towers. If the above factors are not calculated, it will limit the use efficiency of the tower crane and the balance between the hoisting work areas.
