The invention discloses a large
cantilever concrete structure formwork layered anchor pulling construction method and an intelligent
monitoring system, and particularly relates to the field of
building construction.The large
cantilever concrete structure formwork layered anchor pulling construction method comprises the steps that a 16 # I-steel
cantilever heavy frame is installed by pre-burying a high-strength bolt sleeve and conducting three-dimensional positioning; the first to sixth rows of frame bodies are erected layer by layer, a secondary top layer is poured, and the first to fourth phi-20 flower basket pull rods are sequentially installed after top layer concrete is poured; then main and secondary keels and an adjustable jacking are installed, a formwork is laid, and the elevation is corrected to be + / -3 mm;
steel bar numerical control machining straight thread connection and water and
electricity pre-burying are synchronously completed; arranging a
vibrating wire strain gauge, a
spoke pressure gauge and a tilt angle sensor, uploading data to the BIM in real time, and establishing load-deformation dual-threshold early warning; after the formwork is removed, a
scaffold and a main body structure are tied and reinforced in time at the upturning
ridge of the eave gutter on the top layer of the concrete structure according to a wall connecting piece method through steel
pipe fasteners; the formwork and the outer protection frame are integrated, concrete is poured twice, early warning and alarm linkage are achieved, and safety and high efficiency are achieved.
