[0031] Specifically, the thermal insulation composite board in the utility model is mainly applied in a prefabricated thermal insulation composite wallboard such as the application number 202410947009.7 or a prefabricated thermal insulation floor such as the application number 202310690103.4.

[0032] In the utility model, the truss 3 is an integral triangular net rack, the mechanical strength of the truss 3 is maintained, the structure is stressed, when the thermal insulation composite board is cast in situ and installed as a wallboard or a wallboard, the part of the truss 3 exposed outside the thermal insulation board body 1 is wrapped with the heat insulation material 4, the heat insulation material 4 can ensure that heat flow cannot easily pass through the truss 3 and conduct from the cast-in-place concrete layer on one side to the thermal insulation board body 1 or conduct in the opposite direction, the heat bridge is blocked, and the thermal insulation effect of the wallboard or the floor is ensured.
