Construction method and construction platform for high-rise building cantilever structure layer

Abstract

The invention discloses a construction method and a construction platform for a high-rise building cantilever structure layer. The construction method comprises the following steps of: pre-embedding aconnecting steel plate for fixing an ultra-long cantilever I-shaped steel formwork system during construction of a lower two-layer main body structure of the cantilever structure layer; manufacturingthe ultra-long cantilever I-shaped steel formwork system by adopting I-shaped steel; after concrete of the lower two-layer main body structure of the cantilever structure layer is poured and fully solidified, fixedly connecting the ultra-long cantilever I-shaped steel formwork system with the pre-embedded connecting steel plate; laying a formwork on the top surface of the ultra-long cantilever I-shaped steel formwork system and fixedly connecting the formwork with the ultra-long cantilever I-shaped steel formwork system; erecting a scaffold on the top surface of the formwork to serve as the construction platform of the cantilever structure layer. According to the construction method and the construction platform, the construction mode that the scaffold needs to be erected from the groundin the prior art is changed, and the influence on garden forests and small municipal construction in a site before a floor type all-round scaffold is disassembled is avoided; and a large number of steel pipes required for erecting the scaffold are saved, and the construction method and the construction platform have the characteristics of high construction speed and low construction difficulty.

Description

technical field [0001] The invention relates to a construction method and a construction platform for a cantilevered structural layer of a high-rise building, belonging to the technical field of construction engineering. Background technique [0002] With the rapid development of the construction industry, in order to meet the requirements of facade effects in some projects, cantilevered concrete structures of high-rise buildings, especially cantilevered curtain wall structures, abound. If the existing scaffolding method is used for construction, there will be a long period, difficult construction, no turnaround, a larger construction site and more manpower, and a greater impact on the construction period of subsequent garden municipal projects. Therefore, there are still deficiencies in the prior art and need to be further improved.
