Combined wood mould of cast-in-place simply supported beam inner box

The utility model relates to the technical field of building construction, in particular to a combined wood mold of a cast-in-place simply supported beam inner box, which comprises an inner support mechanism mounted on a bottom plate of the inner box, the inner support mechanism comprises a first steel skeleton, a second steel skeleton is arranged at one end of the first steel skeleton, and a third steel skeleton is arranged at one end of the second steel skeleton; a fourth steel skeleton is arranged at the other end of the first steel skeleton, and the fourth steel skeleton, the first steel skeleton, the second steel skeleton and the third steel skeleton surround the inner box frame. The inner supporting mechanism is arranged, rapid building of the cast-in-place simply-supported beam inner box pouring formwork is achieved, meanwhile, the characteristics that a combined steel formwork is high in integrality and short in construction time and a support wood formwork is light in structure and high in economic b
