Cantilever I-shaped steel fixing structure for assembly type laminated slab and construction method

The invention relates to a cantilever I-shaped steel fixing structure for an assembly type laminated slab and a construction method. The construction method comprises the following steps that nuts are pre-buried; positioning the screw rod; pre-burying a screw rod; i-shaped steel is fixed. By means of the mode that the customized nuts are pre-buried in the prefabrication process of the assembly type laminated slab in advance, the pre-buried depth of the screws is increased, and therefore the fixing safety of the cantilever I-shaped steel is improved, and the safety and reliability of the cantilever scaffold are further improved. By means of the mode that the customized nuts are pre-embedded in the laminated slab in advance, the precision of the positions of the screws is improved, the situation of screw deviation is greatly reduced, the scaffold erecting time delayed by adjusting the pre-embedded screws is shortened, and the whole construction progress is accelerated.
