Abstract: Disclosed are a prefabricated thermal insulating composite panel (1), an assembly thereof, a molded panel and a concrete slab comprising the same, and a method and a mold profile (50) for prefabricating the same. The prefabricated composite thermal insulating panel (1) comprises: two reinforcing protective layers (7) of an inorganic noncombustible material, a core (9) formed by a thermal insulating material, a frame (2) with installation grooves (13) surrounding the core (9) and being secured onto the core (9), with the core (9) being placed between the two reinforcing protective layers (7).

Abstract: A concrete slab structural member comprises a frame of cold bend thin wall steel profiles and concrete enclosing the same, in which the main surfaces of two longitudinal cold bend thin wall steel profiles (51, 52, 91, 92) included in each longitudinal cold bend thin wall steel profile keel are parallel to the main surface of the concrete slab, the two longitudinal cold bend thin wall steel profiles (51, 52, 91, 92) are spaced apart and opposite each other along a direction perpendicular to the main surface of the concrete slab, so that a space (200) for the concrete to flow through when it is poured is left between the two longitudinal cold bend thin wall steel profiles. Also provided is a construction method for building a concrete slab structural member.
