Description

Technical Field

[0001] This utility model belongs to the field of near-zero energy buildings, and in particular relates to a sealing structure for curtain wall embedded parts in near-zero energy buildings. Background Technology

[0002] The key to constructing near-zero energy projects is solving the problems of airtightness and sealing thermal bridges, which are also crucial points for inspection and acceptance. Silicon graphene exterior wall curtain cladding has a large number of exposed metal irregularly shaped connectors for embedded parts. When dealing with thermal bridges, it's impossible to cut the entire piece of silicon graphene for placement, which would affect the overall building's airtightness and insulation performance. Therefore, a sealing structure that simultaneously provides excellent airtightness and insulation is needed. Utility Model Content

[0004] Another objective of this invention is to provide a sealing structure for embedded curtain wall components in near-zero energy buildings. Through the synergistic effect of the sealing structure, the silicon graphene polymer slurry layer, and the grid-like steel reinforcement frame, the overall sealing performance and thermal insulation effect of the structure are improved.

[0005] The technical solution of this utility model is as follows: Curtain wall embedded sealing structures for near-zero energy buildings include: The main structure of the curtain wall has embedded parts; A graphene insulation board is located on the outer surface of the main structure of the curtain wall, and the graphene insulation board has a first hole corresponding to the position of the embedded part. A concrete outer sheet, located on the outer surface of the graphene insulation board, and having a second hole corresponding to the first hole; An interface agent layer is applied to the inner surfaces of the first and second holes and to a 100mm wide portion around the outer periphery of the second hole. A silicon-graphene polymer slurry layer is coated on the bottom surface of the first hole; A sealing structure is disposed on the outer surface of the graphene polymer slurry layer, and the outer surface of the sealing structure is flush with the outer surface of the graphene insulation board. The sealing structure has an embedded part receiving hole. A grid-shaped steel reinforcement frame, which is welded to the embedded part and whose ends abut against the inner side of the second hole; A micro-expansion concrete layer is located between the inner side of the grid steel frame and the second hole, and the outer surface of the micro-expansion concrete layer is flush with the outer surface of the concrete outer sheet. Alkali-resistant fiberglass mesh is attached to the surface of the micro-expansion concrete layer and overlaps the outer periphery of the second hole. And two layers of waterproof coating are applied to the surface of the alkali-resistant fiberglass mesh.

[0006] Preferably, in the curtain wall embedded sealing structure for near-zero energy buildings, the sealing structure is a graphene insulation sealing board, and a polyurethane foam layer is provided between the graphene insulation sealing board and the first hole.

[0007] Preferably, in the curtain wall embedded sealing structure for near-zero energy buildings, the sealing structure is a mixture of perlite polystyrene particles and external thermal insulation adhesive mortar in a mass ratio of 3:1.

[0008] Preferably, in the curtain wall embedded sealing structure for near-zero energy buildings, the perlite polystyrene particles and the external insulation adhesive mortar mixture contain silicon graphene insulation particles.

[0009] This utility model has the following beneficial effects: The sealing structure is reliably connected to the silicon graphene insulation board and the concrete outer sheet through the interface agent layer and the silicon graphene polymer slurry layer, which improves its airtightness and waterproofness. The grid-like steel reinforcement frame provides reliable support and connection strength, and through the synergistic effect of the micro-expansion concrete layer, it improves the overall structural reliability.

The concrete outer panel 4 is located on the outer surface of the silicon graphene insulation board 3 and has a second hole corresponding to the first hole; Interface agent layer 5 is coated on the inner surfaces of the first hole and the second hole, and on the outer periphery of the second hole at a width of 100 mm. A silicon-graphene polymer slurry layer 6 is coated on the bottom surface of the first hole; A sealing structure 7 is disposed on the outer surface of the graphene polymer slurry layer 6, and the outer surface of the sealing structure 7 is flush with the outer surface of the graphene insulation board 3.
