Construction method and construction platform for high-rise building cantilever structure layer
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.
本发明公开了一种高层建筑悬挑结构层的施工方法及施工平台，本发明是在悬挑结构层的下两层主体结构施工时预埋用于固定超长悬挑工字钢支模体系的连接钢板；然后采用工字钢制作超长悬挑工字钢支模体系；待悬挑结构层的下两层主体结构的混凝土浇筑完毕并充分固结后，将超长悬挑工字钢支模体系与预埋的连接钢板固定连接；在超长悬挑工字钢支模体系顶面铺设模板并与超长悬挑工字钢支模体系固定连接；在模板顶面搭设脚手架作为悬挑结构层的施工平台。本发明改变了现有技术脚手架需从地面开始支设的施工方式，避免了落地式满堂脚手架拆除前对场地内园林及小市政施工的影响；并节省了大量支设脚手架所需钢管，具有施工速度快，施工难度小的特点。
