Embodiment

[0033] This example takes the R&F Yingkai Plaza project located in the core business district of Zhujiang New Town, Guangzhou as an example. The land area of ​​this project is 7942m 2 , with a total construction area of ​​184,204 m 2 , of which 151573 m above ground 2 , 32631 m underground 2 , 65 floors above ground, 5 floors underground, the foundation pit of the podium is 24.45m deep, the foundation pit in the core tube is 30.9m deep, and the total height of the tower is 296.5m. The main structure is a frame-core tube structure, and the core tube is a reinforced concrete structure.

[0034] According to the characteristics of the vertical structure of the core tube in this example and the actual situation, the inner wall of the core tube, including the inner side of the outer wall, adopts the construction method of self-climbing formwork. Comprehensive consideration of various factors such as progress, safety, and economy requires that a plurality of s...

Abstract

The invention discloses a method for constructing a core tube wall through a self-climbing formwork and the adopted self-climbing formwork. The method comprises the steps that the core tube wall is constructed from bottom to top layer by layer; when a first-layer wall body is constructed, a first pre-buried component is pre-buried, and pouring of the first-layer wall body is completed; after construction of the first-layer wall body is completed, a second-layer wall body is constructed, and a second pre-buried component is pre-buried in the second-layer wall body; each pre-buried component is provided with a wall attachment device, after pouring of the second-layer wall body is completed, a guide rail is arranged between the first wall attachment device and the second wall attachment device, a self-climbing device on the formwork is connected with the guide rail, alternate mutual climbing of the formwork and the guide rail is achieved through the self-climbing device, a form board is arranged on the formwork, and the construction of the core tube wall is completed layer by layer through the form board. The method is suitable for core tube construction of a super high-rise building of a frame core tube structure of 200 m to 400 m, a wide platform is provided for operating personnel for construction, safety is guaranteed well, construction efficiency is greatly improved, and construction cost is lowered.

Description

technical field [0001] The invention relates to a method for constructing a core tube wall by using a self-climbing formwork frame and the self-climbing formwork frame used, belonging to the technical field of high-rise building wall construction. Background technique [0002] With the development of the economy, there are more and more super high-rise buildings over 200 meters, and their structural forms are mostly frame-core tube structures. Generally, during construction, the core tube is used first, and the outer frame steel structure lags behind. Due to the limitation of construction conditions, the traditional method of erecting scaffolding cannot be used for construction. Therefore, it is necessary to find a construction method suitable for the core wall of high-rise buildings. Contents of the invention [0003] The purpose of the present invention is to provide a method for constructing core tube walls using self-climbing formwork and the self-climbing formwork use...
