The invention discloses a fiber-reinforced thermoplastic resin building template. The template is formed by compounding a fiber-reinforced thermoplastic resin felt (1), binding films (2), composite fiber-reinforced felts (3) and surface layer adhesive films (4); the fiber-reinforced thermoplastic resin felt (1) is positioned in the middle; both sides of the fiber-reinforced thermoplastic resin felt (1) are sequentially provided with the binding films (2), the composite fiber-reinforced felts (3) and the surface layer adhesive films (4) from inside to outside; each composite fiber-reinforced felt (3) is formed by compounding a plurality of layers of reinforced fiber felts, wherein each single layer of reinforced fiber felt is of a sandwich structure, a core layer of each single layer of reinforced fiber felt is formed by reinforced fibers (5) and upper and lower surfaces of each single layer of reinforced fiber felt are provided with thermoplastic resin adhesive films (6). The fiber-reinforced thermoplastic resin building template disclosed by the invention has excellent rigidity and weather resistance; the service life of the template can be greatly prolonged; turnover is improved; the surface of the template is wear-resistant and smooth; the template is easy to demould.
