A suspension installation method for steel foundation of tower crane

Abstract

The invention relates to a tower crane steel foundation suspension installing method. The tower crane steel foundation suspension installing method comprises the following steps that (1) a steel foundation is machined according to the distance between two adjacent structure columns on the outer side of a building, namely the size of the cross section of the structure columns; (2) at the appropriate height, the steel foundation is installed between the two adjacent structure columns and extends to the outer side of the building; (3) after unwinding positioning on the steel foundation, machine legs of a tower crane are welded to the steel foundation; and (4) according to installation instructions of specifications of the tower crane, foundation joints, sleeve supports, rotary assemblies, slewing tower joints, tower top supporting frame assemblies, balance arms, cargo booms and the tower crane are totally installed in sequence. The tower crane steel foundation suspension installing methodis simple, quick, low in cost, short in time, saving in energy and high in environmental protection efficiency; meanwhile, the using manner of the tower crane is expanded, the very high practicability is achieved, and the good method is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of building construction machinery and equipment, and in particular relates to a suspension installation method for a steel foundation of a tower crane. Background technique [0002] In the mid-to-late stage of high-rise building construction, a batch of structural parts with a single weight of 16t need to be hoisted to a height of 220m above the ground for use. This height cannot be hoisted by truck cranes. Tower cranes can meet the performance requirements. The lifting weight of a single piece is 16t and the lifting height is 300m. However, the conventional concrete foundation was not considered in the early stage. It is impossible to excavate a large area on the ground around the high-rise building to make a conventional concrete foundation. Using the existing steel strands for hoisting is too slow. Manpower and material resources are wasted, and the construction period cannot be guaranteed, and other lif...
