However, those skilled in the art know that the utility model is not limited to the accompanying drawings and the following embodiments.

Example 1:

The utility model proposes a fire-resistant and heat-insulating structure for exterior or interior walls. As shown in Figure 1, the fire-prevention and heat-preservation structure consists of heat-insulation boards 1 for exterior or interior walls that are sequentially arranged from the inside to the outside. It is composed of the vitrified microbead fire retardant board 2 used for fire resistance of the outer wall or inner wall, wherein the vitrified microbead fire retardant board 2 includes vitrified microbeads and a binder, and the vitrified microbeads are bonded by the binder The vitrified microbead fire retardant board 2 is formed by bonding; the outer wall surface of the heat preservation board 1 and the inner wall surface of the vitrified microbead fire retardant board 2 are fixedly connected. The inside and outside here are relative to the wall. For the external wall insulation, the wall is provided with thermal insulation boards and fire retardant boards in the direction of the external environment; Firestop.

Preferably, the volume percentage of the vitrified microbeads in the vitrified microbead fire retardant plate 2 reaches more than 85 vol%.

Among the vitrified microbeads, the vitrified microbeads with a bulk density of <80kg/m3 account for 0-20vol%, those with a bulk density of 80-120kg/m3 account for 20-40vol%, and those with a bulk density>120kg/m3 Vitrified microbeads account for 40-80vol%.

The thickness of the vitrified microbead fire retardant board meets the fire prevention requirements, for example, 2-15 cm, preferably 5-15 cm, more preferably 6-15 cm.

The binder may be an inorganic binder, for example, the binder includes one or both of sodium silicate and calcium silicate, and the binder may further include calcium oxide and the like. When used, it is added in the form of aqueous solution.

The fixed connection method can adopt the method of bonding the outer wall surface of the thermal insulation board and the inner wall surface of the vitrified microbead fire retardant board.
