Construction method and device of ultrahigh connected group tower outer frame structure

Abstract

The invention discloses a construction method and device of an ultrahigh connected group tower outer-frame structure, and relates to the technical field of building construction equipment. The construction method and device of the ultrahigh connected group tower outer-frame structure aim at solving the problem that in the prior art, a lifting scaffold cannot be integrally lifted according to normal processes because the lifting scaffold is in conflict with an overhung part. The construction device includes a frame main body, a guide frame, a wall-attached device and an outer protection net, wherein the frame main body surrounds the outer side of the outer-frame structure, the guide frame is vertically fixed to the inner side of the frame main body, and the two ends of the wall-attached device are detachably connected with a cast floor plate and the guide frame respectively. The construction method includes the steps that after the frame main body is lifted for the nth time, the construction device is located at the bottom of the overhung part; the components, in conflict with the overhung part, of the frame main body are removed in advance, and after being lifted to an appropriateposition, the frame main body is connected to the cast floor plate through the wall-attached device; the components, not in conflict with the overhung part, of the frame main body are restored, lifting is completed for the (n+1)th time, and the Nth layer of the outer-frame structure is constructed; in this way, operation is repeatedly conducted till the frame main body crosses the overhung part, and all structural layers where the overhung part is located are constructed layer by layer.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a construction device and a construction method for an outer frame structure of super-high conjoined group towers. Background technique [0002] At present, super high-rise buildings are developing rapidly in China, and their functions and shapes are becoming more and more complex. Super high-rise conjoined tower structures are one of the types of buildings. Rigidly connected super high-rise conjoined towers not only have the mutual support of tower structures in terms of structural stress At the same time, it has the functions of interconnection and intercommunication, which is convenient for fire organization. [0003] According to the construction sequence of the ultra-high conjoined tower structure, it can be divided into three main construction methods: one is to construct the group tower structure alone, and then use the overall lifting method to con...

AI Technical Summary

Problems solved by technology

[0005] In view of the interference and conflict between the existing lifting scaffold and the overhanging components on the super-high conjoined tower structure, and the continuous large and high floors cannot meet the limit of the cantilever height of the lifting scaffold, resulting in the problem that the lifting scaffold cannot be lifted as a whole according to the normal process, The purpose of the present invention is to provide a construction device and construction method for the outer frame structure of a super-high conjoined group tower, which implements partial and orderly dismantling and fills in the parts of the main body of the frame body that conflict with the overhanging components, and by adding detachable The wall-attached device stably connects the frame body to the poured floor of the outer frame structure, so as to realize the overall lifting of the frame body and pass over the overhanging components safely and efficiently
