The invention discloses a hollow plastic building formwork and solves problems that existing plastic formworks are low in strength and nails are prone to fall off during usage. The hollow plastic building formwork comprises an upper die and a lower die which are mutually parallel and made of plastics and further comprises a reinforcing rib group which is disposed between the upper die and the lower die, the reinforcing rib group comprises at least two X-shaped reinforcing ribs that are sequentially connected side by side and transverse reinforcing ribs that penetrate cross points of all X-shaped reinforcing ribs, the X-shaped reinforcing ribs and the transverse reinforcing ribs are made of plastics, equilateral triangle cavities are formed between the upper die and the X-shaped reinforcing ribs, between the transverse reinforcing ribs and the X-shaped reinforcing ribs and between the lower die and the X-shaped reinforcing ribs, and projections are arranged on the upper die and the lower die. The hollow plastic building formwork has the advantages that the structure is simple, the usage is convenient, the strength is high, and formworks are firmly spliced.
