Structure at joint of silicon graphene thermal insulation outer wall and cast-in-place structure and construction method thereof

According to the structure of the joint of the silicon graphene heat preservation outer wall and the cast-in-place structure and the construction method of the structure, a prefabricated outer wall with a lower notch formed in the bottom is adopted, and due to the existence of the lower notch, a silicon graphene heat preservation layer on the prefabricated outer wall is not prone to being collided and collided to be damaged and broken; due to the fact that the lower notch and the supporting bottom beam of the cast-in-place structure floor form the containing space, the waterproof layer is laid in the containing space, and the heat preservation protection plate is additionally arranged after the waterproof layer is embedded in the containing space, a good waterproof measure is formed, a complete outer wall heat preservation measure can be formed, and the heat preservation and waterproof effects of the structure are effectively guaranteed. The problems that a heat preservation layer at the bottom of an existing
