Technical Field
The utility model relates to the field of assembled buildings, in particular to a cement-based polymer and AAC combined external wall male corner connection structure.
Background
AAC is an abbreviation of Autoclaved Aerated Concrete (autoclaved aerated concrete), which is a novel lightweight porous building material. The AAC material is prepared from silica sand, cement, lime, gypsum and other raw materials through the technological processes of proportioning, stirring, casting, pre-curing, cutting, high-pressure steam curing and the like. In the production process, a large number of closed micropores which are uniformly distributed are formed in the concrete by adding foaming agents such as aluminum powder, so that the density of the material is greatly reduced, the heat preservation and insulation performance is improved, and meanwhile, the higher strength is maintained. The AAC material has the advantages of light weight, high strength, good heat preservation and insulation performance, excellent sound insulation effect, excellent earthquake resistance, convenient construction, environmental protection and sustainability, and the like, and is widely applied to various building structures such as walls, floors, roof boards, fireproof isolation walls and the like. In the modern building industry, AAC is increasingly applied and popularized as a green energy-saving building material. The AAC board has the characteristics of light weight, heat preservation, heat insulation, fire prevention, sound insulation, environmental protection, convenient construction, good economy, recycling and the like, and is widely applied to modern buildings. However, due to the porous structural characteristics, the waterproof and moistureproof performances of the wall body are poor, the wall body can be used as an indoor filling wall body at present when being used as a wall body material, but cannot be used as an outer wall body of a building, and the wall body is poor in earthquake resistance after assembly, so that the wall body is greatly limited in use in a bearing wall body.
The novel technology is provided, AAC and cement-based polymers are combined to form the wallboard, a coating layer structure is formed on the surfaces of single or multiple AAC boards through the cement-based polymers, and compared with a single AAC wallboard, the formed combined wall can greatly improve the seepage-proofing performance and the structural strength, has the advantages of AAC, and is a novel assembled building material with wide application prospect. However, the prior art lacks of practical application technology of the combined wall body, and does not refer to the prior art of which structure is adopted as the corner of the wall body when the combined wall body is used as an outer wall, so that a corner construction technology for the combined outer wall of the cement-based polymer and the AAC is urgently needed.
