Problems solved by technology

[0004] The jacking steel platform has a great influence on the section and section of the steel plate wall. A large number of high-altitude operations and construction complexity determine that the core tube part of the super high-rise building needs an intelligent jacking steel platform, and the unreasonable section and section structure of the steel plate wall The hoisting construction efficiency of the steel plate wall is slow, and the welding is difficult, which affects the progress and efficiency of the cross construction

specific Embodiment approach

[0017] The segmented and segmented structure of the steel plate wall under the influence of the intelligent jacking steel platform truss of the present invention, its preferred specific implementation mode is:

[0018] The steel plate wall of the core tube is segmented in the elevation direction according to the following structure, and each segment is segmented in the plane direction:

[0019] The height of each section of the steel plate wall is the same as the standard height of the top form;

[0020] When each section of the steel plate wall is segmented, the part of the structure under greater stress is staggered, and the longitudinal welds are staggered, and the length of the segment makes the distance between the position of the steel concealed beam and the weld greater than 400mm.

[0021] The weight of each steel plate wall is less than or equal to 23.2 tons.

[0022] The steel plate wall is divided into sections according to one floor, and the height is 4.5m.

[00...

specific Embodiment

[0026] Segmentation and section considerations:

[0027] (1) When the steel members of the core tube are segmented, the parts of the structure under greater stress should be staggered, and the longitudinal welds should be staggered as far as possible. After segmenting and segmenting, the unit components should have overall stability to prevent excessive deformation during transportation and hoisting. Comprehensively considering the impact of steel plate wall segmentation and section, intelligent jacking steel platform truss, electromechanical and various specialties, a reasonable segmentation scheme is formulated to facilitate installation.

[0028] (2) The segment length and width meet the transportation conditions, which are convenient for on-site measurement and the size restrictions caused by the primary and secondary trusses of the intelligent jacking steel platform. Considering that the step distance between the top formwork system and the steel plate wall construction ...

Abstract

The invention discloses a structure for segmenting and sectioning a steel plate wall under influence of trusses of an intelligent jacking steel platform. The steel plate wall of a core tube is sectioned in the vertical surface direction in the following structure, and each section of the steel plate wall is segmented in the plane direction: the height of each section of the steel plate wall is the same with the standard jacking height of an ejection die, and one layer of the steel plate wall is taken as one section and is 4.5 m high; parts, bearing more force, of the structure are staggered when each section of the steel plate wall is segmented, longitudinal welding seams are staggered, and the length of each segment of the steel plate wall allows the distance between a steel hidden beam and the welding seams to be larger than 400 mm. Each segment of the steel plate wall is smaller than or equal to 23.2 tons. Influences of staggered main and auxiliary trusses of the jacking platform on hoisting can be avoided, the steel plate wall can be quickly and efficiently mounted, welding and hoisting times are reduced, time is earned for civil engineering concrete pouring, steel bar binding and other procedures, the time cost is saved, and the maximum economic benefits can be created.

Description

technical field [0001] The invention relates to a super high-rise building core tube construction technology, in particular to a segmented and segmented steel plate wall structure under the influence of an intelligent jacking steel platform truss. Background technique [0002] In super high-rise construction, the core tube structure is mostly designed with steel plate walls, and the existing super high-rise buildings mostly use jacking steel platforms for core tube construction. [0003] Such as figure 1 , figure 2 As shown, the intelligent jacking platform system includes support and jacking system, steel truss system, hanger and formwork system, etc. The complex structure has a great influence on the segmented section of the steel plate wall. [0004] The jacking steel platform has a great influence on the section and section of the steel plate wall. A large number of high-altitude operations and construction complexity determine that the core tube part of the super hi...
