Positioning and supporting mechanism for staggered slab concrete pouring side formwork

The utility model discloses a positioning and supporting mechanism for a staggered slab concrete pouring side formwork. The positioning and supporting mechanism solves the problem that an existing staggered slab concrete pouring side formwork is unstable in supporting and positioning. An inverted-V-shaped support (5) is arranged on a low-span floor plate concrete pouring bottom formwork (1), a step-shaped supporting rod (6) is fixedly connected to the top end of the inverted-V-shaped support (5), the bottom end of the step-shaped supporting rod (6) is arranged on the low-span floor plate concrete pouring bottom formwork (1), and the step-shaped supporting rod (6) and the inverted-V-shaped support (5) form a three-leg supporting frame. A hook (7) is arranged at the upper end of the step-shaped supporting rod (6), the hook (7) is connected with a high-span floor plate pre-embedded main rib (3) in a hanging mode, and a slab staggering concrete pouring side formwork (4) is arranged on an upper step rod of the ste
