Construction method of cantilever construction platform with ultrahigh cast-in-place flaring structure in cylindrical building

Abstract

A construction method of a cantilever construction platform with an ultrahigh cast-in-place flaring structure in a cylindrical building comprises the steps that theoretical mechanical analysis is carried out to the ultrahigh flaring structure of the cylindrical building; a temporary operation platform is set up; girders are embedded into a shear wall of the cylindrical building, and concrete is poured; corner connecting beams are set up on the girder, and the girders are connected into a stressed whole body; reinforcing steel bars are welded on the girders in order to fix uprights of a formwork and an outer scaffold; reinforcing steel bar rings are embedded, and steel wire ropes are tensioned; the formwork system and the outer scaffold are set up on the girders; and an upper flaring structure template and binding reinforcing steel bars are set up, and the concrete is poured. In the construction method of the cantilever construction platform with the ultrahigh cast-in-place flaring structure in the cylindrical building provided by the invention, cantilever joist steel is embedded as a supporting foundation and the embedded joist steel and the shear wall are welded to transfer upper downward loads to the foundation in order to form a stable system. By setting up cantilever supporting platforms of outer scaffold engineering and template engineering using the construction method, construction safety can be ensured effectively, construction cost can be reduced, construction duration can be shortened, and good economic effects can be reached.

Description

technical field [0001] The invention relates to the technical field of construction of high-altitude cantilevered structures, in particular to a construction method for a cantilevered construction platform of an ultra-high cast-in-place floating structure of a cylindrical building. Background technique [0002] The history of human development is the history of architectural development. From prehistoric humans living in caves to modern humans living in the air, humans continue to develop and architecture continues to move forward. The development of architecture lies in the continuous improvement of people's requirements for the appearance, shape and function of buildings. In addition to the continuous development of modern buildings towards super high buildings, the development and expansion of the shape of buildings in the air has given rise to cantilevered structures. Cantilevered structures are important for A breakthrough and innovation of traditional architectural for...

Problems solved by technology

In domestic similar research, mainly for medium and high-rise buildings, floor fastener type steel pipe scaffolding can be used to erect, or the length of the cantilever is small. When setting up a cantilevered platform in China, L is the length of the cantilever, and the length of the inner anchor is 1.25 L, there is enough safety protection distance, but when the building does not have enough internal anchors or the internal anchor distance is too long, the cost of materials, hoisting, etc. will increase, which is not conducive to economic benefits

At the same time, there are not enough cantilevered construction platforms for the study of the floating structure of the super-tall building. Therefore, the research on the cantilevered construction platform of the super-tall building is carried out to maintain the safety during the construction process. Further research Construction technology is inevitable
