Abstract
The utility model discloses an inner formwork of a prefabricated box girder and the prefabricated box girder. The inner formwork of the prefabricated box girder comprises a formwork sheet and an inner formwork panel formed by splicing a plurality of pieces of long-strip-shaped steel, wherein the inner formwork panel is fixed on the outer side of the formwork sheet in an enclosing mode. The inner formwork of the prefabricated box girder does not need heavy machines of a small gantry crane and the like, so that installation difficulties are reduced. During disassembly, the long-strip-shaped steel only needs to be disconnected with the formwork sheet, and the inner formwork can naturally disintegrated, so that the inner formwork is convenient to disassemble and short in consumed time. In addition, compared with an inner formwork panel adopting a whole piece of steel, the inner formwork panel adopting the long-strip-shaped steel is small in self-weight and can improve anti-deformation capacity of the whole inside through a method for manufacturing the formwork by increasing the formworks or adopting a material with higher rigidity, and therefore anti-deformation capacity of the inner formwork of the prefabricated box girder is stronger.
