Structure system of concrete building for self-heat insulation

A structure system of a concrete building, comprising:

• at least two heat insulated walls, wherein the at least two heat insulated walls include:
• a first layer of prefabricated concrete panels spaced apart by a first plurality of cast-in-place concrete wall vertical ribs, wherein each of the prefabricated concrete panels of the first layer of prefabricated concrete panels have an inner surface and at least two protruding edges,
• a second layer of prefabricated concrete panels spaced apart by a second plurality of cast-in-place concrete wall vertical ribs disposed therein, wherein each of the prefabricated concrete panels of the second layer of prefabricated concrete panels have an inner surface and at least two protruding opposing edges, further wherein the second layer of prefabricated concrete panels is positioned opposite the first layer of prefabricated concrete panels;
• a first heat insulating layer covering the inner surface of each of the prefabricated concrete panels to form a continuous heat insulating barrier, the first heat insulating layer conforming to the inner surface of the prefabricated concrete panels, wherein a union of the first heat insulating layer and the prefabricated concrete panels form a prefabricated concrete unit;
• wherein the prefabricated concrete unit formed by the union of the heat insulating layer and the prefabricated concrete panels of the first layer is cross-linked with the prefabricated concrete unit formed by the union of the heat insulating layer and the prefabricated concrete panels of the second layer, such that the at least two protruding edges of the prefabricated concrete panels of the first layer of prefabricated concrete panels contact the first heat insulating layer conforming to the inner surface of the prefabricated concrete unit formed by the union of the heat insulating layer and the prefabricated concrete panels of the second layer;
• a link beam disposed between the at least two heat insulated walls to connect the at least two heat insulated walls together, wherein an outer wall end face of said link beam is covered with an additional heat insulation layer;
• and
• a floor slab cast to be integral with the link beam, the floor slab including a prefabricated concrete floor slab formed by a floor slab concrete panel having at least two protruding edges and a second heat insulating layer, and a cast-in-place floor slab, wherein the prefabricated concrete floor slab and the cast-in-place floor slab are cast to be integral.
