Description

Technical Field

[0001] The utility model relates to the field of passive low-energy consumption building construction, in particular to a hole repairing structure for an insulation layer of an ultra-low-energy consumption residential exterior wall. Background Art

[0002] The exterior walls are responsible for the greatest heat loss within the building envelope, accounting for approximately 30% of the building's total heat consumption. A continuous and complete exterior insulation layer is crucial to prevent thermal bridges and maintain thermal stability within the building. However, existing residential exterior walls, due to curtain wall installations, have holes created in the insulation layer due to embedded components in the exterior wall structure. These holes, in turn, create thermal bridges, necessitating repair. The typical repair method involves filling the holes with insulation material and sealing them with mortar. While this repair reduces the likelihood of thermal bridges, the holes are not fireproof. Utility Model Content

[0003] The purpose of the utility model is to modify the construction hole of the external insulation layer of the exterior wall by combining silicon graphene insulation material with aerogel insulation coating system, thereby improving the fire resistance while avoiding thermal bridges.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A structure for repairing holes in the exterior wall insulation layer of an ultra-low energy consumption residential building is disclosed. Holes in the exterior wall insulation layer provided with connectors are filled with silicon-graphene insulation material, and a mesh cloth composite anti-cracking mortar layer and an aerogel insulation coating system layer are sequentially provided on the surface of the silicon-graphene insulation material.

[0006] Preferably, the mesh cloth composite anti-cracking mortar layer expands 200 mm around the hole.

[0007] Preferably, the silicon-graphene thermal insulation material and the mesh cloth composite anti-cracking mortar layer are bonded by an adhesive layer.

[0008] Preferably, an aerogel-specific putty layer is provided between the mesh cloth composite anti-cracking mortar layer and the aerogel thermal insulation coating system layer.

[0009] Preferably, the silicon graphene thermal insulation material is silicon graphene, which is a Class A fireproof material, and the aerogel thermal insulation coating system layer adopts an aerogel thermal insulation coating system, which is a Class A fireproof material.

[0010] The hole repair component of the external insulation layer of the exterior wall of the utility model adopts Class A fireproof silicon graphene material and aerogel insulation coating system, which avoids the generation of thermal bridges in the external insulation layer to the greatest extent possible and improves the fire resistance.

[0011] The use of a mesh cloth composite anti-cracking mortar layer can prevent the repair layer from cracking and improve the overall strength of the repair structure.

[0012] The hole repairing structure of the utility model has a simple structure and is easy to construct. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model discloses a hole repair structure for the exterior wall insulation layer of an ultra-low energy consumption residential building, wherein the holes of the exterior wall insulation layer provided with connectors are filled with silicon graphene insulation material, and a mesh cloth composite anti-cracking mortar layer and an aerogel insulation coating system layer are sequentially provided on the surface of the silicon graphene insulation material.

[0017] See attached Figures 1 to 3 , the hole repair structure of the insulation layer is further illustrated by examples.

[0018] The utility model is a structure for repairing holes in the thermal insulation layer of an ultra-low energy consumption residential exterior wall. Figure 1 As shown in the figure, it mainly consists of base wall ①, external wall insulation layer ②, silicon graphene insulation material ③, mesh cloth composite anti-cracking mortar ④, and aerogel insulation coating system ⑤.

[0019] During construction of the base wall (①), curtain wall connecting steel plates are embedded, creating a construction hole in the exterior insulation layer (②). For example, the hole size is 350mm x 250mm, and the hole depth depends on the specific project. A curtain wall connector (⑥) is installed in the hole. One end of the connector is fixedly connected to the pre-embedded connecting steel plate in the base wall, while the other end protrudes from the insulation hole. The hole is then filled with a new silicon-graphene insulation material (③). Silicon-graphene insulation material (③) is a Class A fireproof material. After filling, a mesh composite anti-cracking mortar (④) is applied to the surface of the silicon-graphene insulation material (③). The mesh composite anti-cracking mortar (④) needs to be applied 200mm around the hole. A special adhesive is used to bond the silicon-graphene insulation material (③) to the mesh composite anti-cracking mortar (④). Finally, an aerogel insulation coating system (⑤) is applied over the mesh composite anti-cracking mortar (④). Aerogel special putty needs to be used for treatment between the mesh cloth composite anti-cracking mortar ④ and the aerogel insulation coating system ⑤.
