Construction method of rhombic #-shaped floor formwork supporting system based on high formwork

The invention belongs to the field of building construction, and relates to a construction method of a rhombus #-shaped floor system formwork supporting system based on a high formwork. The construction method of the rhombus #-shaped floor formwork supporting system based on the high formwork comprises the following steps that S1, a first supporting bracket is erected; s2, beam bottom formworks are fully laid at the upper ends of the first supporting supports, and an integral bottom formwork platform is formed; s3, multiple groups of cross beam steel bars are bound on the integral bottom die platform; s4, beam side formworks are installed on the side edges of each set of cross beam steel bars, the bottoms of the beam side formworks are attached to the upper surface of the overall bottom formwork platform, and a formwork cavity is defined by the beam side formworks and the upper surface of the overall bottom formwork platform in a combined mode; s5, a second supporting bracket is erected on the upper surface o
