The invention discloses a hollow dismounting-free polypropylene building formwork with a wall thermal-insulation function. The building formwork comprises a hollow internal wall formwork, a hollow external wall formwork, T-shaped anchoring rods and hexagonal socket nuts, wherein the hollow internal wall formwork and the hollow external wall formwork are made of three-layer or four-layer hollow polypropylene plates. The building formwork made of the hollow polypropylene plates is light and convenient to construct; the hollow structure has excellent thermal-insulation and sound-proof effects, and flower-shaped notch grooves distributed in a staggered manner are adopted to separate vertical ribs in the hollow polypropylene plates; the thermal expansion coefficient of the plates is decreased, so that the plates can be well attached to a concrete wall, meanwhile, construction procedures of formwork dismounting and external wall thermal-insulation are reduced, and higher social benefits and economic benefits are realized.
