Concrete prefabricated assembly tower crane foundation structure and laying method thereof

Abstract

The invention discloses a concrete prefabricated assembly tower crane foundation structure and a laying method thereof. The structure comprises a center structure and a plurality of transition structures; the center structure detachably abuts against and is connected with the first ends of the transition structures; the second ends of the transition structures detachably abut against and are connected with end structures; the transition structures and the end structures are arranged at the same height; the center structure, the transition structures and the end structures are provided with prestress holes; and the center structure, the transition structures and the end structures can be tensioned, assembled and fixed through steel strands penetrating the prestress holes. The problems that an existing tower crane foundation is long in work period, environment pollution is likely to be caused, land is wasted, and circulation is not convenient are solved. The tower foundation optimized plane technology is adopted, prefabricated assembly can be achieved, the anti-overturning capability of the tower crane foundation is effectively improved, usage is safer and more reliable, the construction safety period is short, environment friendliness is achieved, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of hoisting and transportation in the construction industry, in particular to a foundation structure of a concrete prefabricated and assembled tower crane and a laying method thereof. Background technique [0002] Tower crane is one of the important equipment for hoisting and transportation operations in the construction industry. The vertical transportation of construction materials such as steel bars, wooden corrugations, and scaffolding pipes for construction is completed by tower cranes. In order to ensure the normal and safe operation of the tower crane, the tower crane must be fixedly installed on the foundation of the tower crane, and at the same time, it must be ensured that the foundation of the tower crane has sufficient anti-subversion ability. [0003] In traditional tower crane foundation construction, a deep foundation pit needs to be dug, poured and rammed with reinforced concrete, and a certa...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a concrete prefabricated assembled tower crane foundation structure and its laying method, which solves the problems of the existing tower cranes, such as long foundation work period, easy environmental pollution, waste of land and inconvenient turnover. The optimized plane technology of the tower base can be prefabricated and assembled, which effectively improves the anti-overturning ability of the tower crane foundation, making it safer and more reliable to use, with a short construction safety cycle, environmental protection and resource saving
