Abstract
The utility model relates to a reinforcing sandwich-type composite building template which is formed by consecutively hot-pressing an outer-layer sheet and a middle layer core material. Side sealing edges are arranged around the core material. Four corners of the core material are provided with apex angle reinforcers. The reinforcing sandwich-type composite building template does not need wood and glue so as to be favorable to environment protection; is light in weight due to the fact that the core material is made of a cellular board, a foaming board, or other low-density thermoplastic materials; not prone to damage and long in service life due to the fact that the apex angle reinforcers and side sealing edge treatment are adopted for the core material; and is simple in technology and high in production cost due to the fact that a consecutive hot-pressing forming method is adopted at production time.
