Composite exterior wall structure and assemblies

The embodiments of the invention provide a composite exterior wall structure and assemblies, and relates to the field of buildings. The composite exterior wall structure includes a first vane board, asecond vane board, a concrete layer and a thermal insulation layer. The first vane board, the concrete layer, the thermal insulation layer and the second vane board are arranged in a stacked mode insequence. The second vane board is provided with a second hole. The second hole penetrates through the thermal insulation layer and extends to the concrete layer at least. The second vane board is further provided with a first hole. The first hole is located below the second hole. The first hole penetrates through the thermal insulation layer and extends to the concrete layer. According to the composite exterior wall structure and assemblies, the first hole penetrates through the thermal insulation layer and extends to the concrete layer, the situation that the thermal insulation layer is crushed due to the fact that t
