Embodiment 1

[0044] Please refer to Figure 1 to Figure 14 , A detailed description of the electronically controlled rotary-lift steel platform integral lifting device and construction method of the present invention.

[0045] Such as Figure 1 to Figure 14 As shown, the core tube of this embodiment has a Tian-shaped configuration. The core tube has four inner tubes. The standard layer of the core tube has a height of 3.9m. In the n+1 section of the core tube, the standard layer 301 and the core tube A number of corbel bearing pin shells 308 are provided at the lower part of the inner cylinder side wall of the n+2 section standard layer 302, the core tube n+3 section standard layer 303, and the core tube n+4 section standard layer 304. The corbel bearing pin shell 308 is a trough-shaped prefabricated steel member, which is used to extend and rest the corbel 401 during the core tube reinforced concrete pouring stage. The resting corbel 401 transfers the load of the entire steel platform it bea...

Embodiment 2

[0057] Please continue to refer Figure 1 to 14 This embodiment provides a construction method for constructing the core tube structure of a super high-rise building. The main steps of the construction method are as follows:

[0058] Step 1: Complete the combined installation of the spin-up system, steel platform system, and bottom support system according to the design requirements to meet all the conditions for carrying out the construction of the super high-rise core tube structure; at this time, the shelving corbel 401 is located in the n+1 section of the core tube Within the corbel bearing pin shell 308 on the inner cylinder wall of the standard layer 301; the lifting steel template 307 is fixed on the n+3 section standard layer 303 of the core cylinder. The n+3 section standard layer 303 of the core cylinder has sufficient strength.

[0059] Step 2: Improve preparation. Firmly fix the lifting column support 102 on the upper end of the standard layer 303 of the n+3 section of...

Abstract

The invention discloses an electric-control rotary lifting type steel platform integral lifting device and a construction method thereof, belongs to the technical field of super high-rise building construction, and aims at solving the problems that in the integral steel platform lifting process, a lifting device is large in self weight and discontinuous in lifting and needs artificial assistance.The device is composed of a rotary lifting system, a steel platform system and a bottom supporting system. The construction method comprises the steps that combined installation of the rotary liftingsystem, the steel platform system and the bottom support system is completed; a motor is started to enable a rotary lifting wheel to start forward rotation, and the gravity load of the whole steel platform system is completely borne by the rotary lifting system for lifting preparation; then the motor is operated to complete the whole lifting of one standard layer of the steel platform system; thenan electric control system of the rotary lifting system is closed, so that the gravity load of the whole steel platform system is completely borne by the bottom support system; then the constructionof a reinforced concrete structure of one standard layer is completed; and finally, the next standard layer is lifted.

Description

Technical field [0001] The invention relates to an integral lifting device and a construction method for an electronically controlled rotary lifting steel platform, and belongs to the technical field of super high-rise building construction. Background technique [0002] The construction of super high-rise buildings in my country mainly adopts two technical systems: integral steel platform system and hydraulic climbing formwork system. The integral steel platform is the construction technology system of super high-rise buildings generally recognized by the construction engineering community in my country. It is used in the Oriental Pearl TV Station, Shanghai Jinmao Building, It has been fully implemented in major projects such as the World Financial Center and Shanghai Center, and a relatively complete technical system has been formed. The overall steel platform system has been widely used in the construction of super high-rise buildings in my country. [0003] At present, the overa...
