The invention relates to a construction method for an accurately pre-buried
junction box based on BIM and an aluminum
alloy formwork. The construction method comprises the following operating steps that (1) the BIM technology is utilized,
civil engineering and mechanical and
electrical installation models are established, position, functionality and
collision checking is conducted, and a mechanical and
electrical installation construction drawing is deeply optimized; (2) according to a deeply-optimized construction
blueprint, a BIM model is established, the splicing dimension, position and sequence of the aluminum
alloy formwork are determined, and the aluminum
alloy formwork with the determined splicing dimension is subjected to factory
sizing manufacturing; (3) through
junction box position information recorded by the BIM model, positioning clamp plates are manufactured on the aluminum alloy formwork while
sizing manufacturing is conducted; and (4) during the construction stage of aluminum alloy formwork installation in concrete wall body construction, the
junction box is installed according to the positions of the positioning clamp plates, and when concrete wall body construction is completed and the aluminum alloy formwork is dismantled, the junction box is accurately reserved in a concrete wall body. The invention further relates to the aluminum alloy formwork with the accurately pre-buried junction box, and the pair of positioning clamp plates are arranged on the inner side face of the aluminum alloy formwork.
