A staggered construction method of floor-mounted tower cranes attached to the structure of super high-rise buildings

Abstract

The invention discloses a staggered construction method for external attachment floor type tower cranes of a super high-rise building structure. The staggered construction method comprises the following steps: 1, mounting and positioning the double floor type tower cranes; 2, attaching a first tower crane of the first floor type tower crane on a wall; 3, jacking the first floor type tower crane; 4, hoisting a core cylinder; 5, constructing a steel-structure outer framework and attaching a second tower crane of the second floor type tower crane on the wall; 6, jacking the second floor type tower crane; 7, lifting the core cylinder again; 8, constructing the steel-structure outer framework again; 9, taking a (N+2Q)th layer of the steel-structure outer framework as an Nth layer structure of the steel-structure outer framework and circulating step 2. According to the staggered construction method disclosed by the invention, two sets of the common floor type tower cranes are distributed onan external wall of a building in a manner of staggering up and down and are used for carrying out alternating jacking construction, so that the engineering investment of construction units is reduced; the staggered construction method is not restricted by regional power supply of regions, is economical and reasonable and is convenient and safe to mount and dismount; a building technological levelof super high-rise buildings is promoted and reference and evidence are provided for construction of similar buildings in the industry.

Description

technical field [0001] The invention belongs to the technical field of floor-to-ceiling tower crane construction, and in particular relates to a staggered construction method of floor-to-ceiling tower cranes attached to the outside of a super high-rise building structure. Background technique [0002] With the continuous rise of super high-rise buildings in our country, all kinds of tower cranes are blooming, and the development and application of tower cranes are more and more. The main parameters such as lifting speed, slewing speed, luffing speed, walking speed, jacking speed, lifting capacity, lifting moment, etc., as well as the geometric dimensions such as the outrigger span and tail turning radius of the lower slewing tower crane are strictly regulated, so that Seriously limit the technical progress of the tower crane. In the current market, due to the comprehensive constraints of the regional economic level, the project investment level of the construction unit, the...

[0002] With the continuous rise of super high-rise buildings in our country, all kinds of tower cranes are blooming, and the development and application of tower cranes are more and more. The main parameters such as lifting speed, slewing speed, luffing speed, walking speed, jacking speed, lifting capacity, lifting moment, etc., as well as the geometric dimensions such as the outrigger span and tail turning radius of the lower slewing tower crane are strictly regulated, so that Seriously limit the technical progress of tower cranes

In the current market, due to the comprehensive constraints of the regional economic level, the project investment level of the construction unit, the power supply capacity of the city in the project area, and the economic capacity of the construction unit, in the face of the construction of super high-rise buildings below 300 meters in height, the use of boom-type tower cranes and The arrangement of internal climbing tower cranes in the reinforced concrete core tube of super high-rise buildings will greatly increase the project cost of the construction unit and the construction unit
