Technical Field
The utility model relates to the field of assembled buildings, in particular to a cement-based polymer and AAC combined exterior wall sequential connection structure.
Background
AAC is an abbreviation of AutoclavedAeratedConcrete (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 practical application technology of the combined wall, and no reference is made to the prior art about the structure adopted between adjacent wall units as the outer wall, so that a sequential construction technology for the combined outer wall of the cement-based polymer and the AAC is urgently needed.
Disclosure of utility model
The utility model aims to provide a cement-based polymer and AAC combined outer wall joint structure so as to realize the joint between adjacent external wall boards when the cement-based polymer and AAC combined outer wall is used as an assembled building outer wall.
The cement-based polymer and AAC combined exterior wall sequential connection structure comprises at least two exterior wall boards, wherein the exterior wall boards comprise one or more AAC boards which are fixedly connected into a whole on the surface by the cement-based polymer, the cement-based polymer at least covers the side surfaces and the exterior wall surfaces of the AAC boards to form a waterproof layer, the cement-based polymer is outwards stretched on the left side and the right side of the exterior wall surface of the exterior wall board to form an exterior wall board, the AAC boards are outwards stretched on the left side and the right side of the interior wall surface of the exterior wall board to form an interior wall board, the two adjacent exterior wall boards are arranged in a flat angle to enable the side walls of the exterior wall board, the interior wall board and the exterior wall board to be enclosed to form a sequential connection cast-in-place space, and the cement-based polymer is poured in the sequential connection cast-in-place space to form a connecting strip connected between the two adjacent exterior wall boards.
Preferably, as a modification, the waterproof layer and the outer baffle formed by the cement-based polymer are both 2-4mm thick.
Preferably, as a modification, the outer baffle is parallel and flush with the outer wall surface of the combined outer wall panel.
Preferably, as a modification, the length of the outer baffle plate and the inner baffle plate extending to the side wall of the outer wall plate is 20-130mm.
Preferably, as a modification, the thickness of the inner baffle is 20-40mm.
Preferably, as an improvement, the lengths of the outer baffle plate and the inner baffle plate extending to the side wall of the outer wall plate are the same.
The utility model provides a cement-based polymer and AAC combined external wall sequential connection structure, which aims to solve the problem of lack of an effective connection method in the prior art, and ensure that good sealing property and structural stability can be realized when the composite material wallboard is used in an assembled building. When the external wall panel is practically applied, the external wall panel main body consists of an AAC plate in the middle and a cement-based polymer layer coated outside the pouring layer, and the cement-based polymer improves the waterproof and impervious performances of the external wall panel external facade in a prefabricated mode, improves the overall structural strength of the external wall panel, and has better anti-seismic and anti-cracking performances. Meanwhile, the inside AAC plate ensures that the whole quality of the external wall board is lighter than that of the traditional external wall boards and other external wall boards under the same condition, and has the characteristics of heat preservation, heat insulation, fire prevention, sound insulation, environmental protection, convenience in construction, good economical efficiency and the like.
By combining the cement-based polymer with the AAC board, a new composite wallboard is formed. The cement-based polymer not only forms a waterproof protective layer on the surface of the AAC board, but also can enhance the structural strength and durability of the whole wallboard.
In order to achieve effective connection between adjacent external wall panels, a unique sequential construction is devised. The two sides of each external wall panel extend outwards to form an external baffle and an internal baffle, and the external baffles and the side surfaces of the external wall panels jointly enclose a sequential cast-in-situ space. In the construction process, cement-based polymer can be poured in the space to form a connecting strip for connecting two adjacent external wallboards, so that the continuity and stability of the whole wall body are ensured.
In order to ensure the effectiveness of the sequential structure and the convenience of construction, the sizes of the outer baffle and the inner baffle are optimally designed. For example, the outer baffle is parallel and level with the outer wall surface of the combined outer wall plate, the length of the outer baffle and the inner baffle extending out to the side wall of the outer wall plate is 20-130mm, the thickness of the inner baffle is 20-40mm, and the thicknesses of the waterproof layer and the baffles are 2-4mm. The setting of the dimensions ensures the stability of the structure and is convenient for construction operation.
The advantages of the utility model include:
The anti-seepage performance is improved by coating cement-based polymer on the surface of the AAC board to form a compact waterproof layer, so that moisture can be effectively prevented from penetrating into the wall. Meanwhile, the sealing performance between the adjacent wallboards is further enhanced by the connecting strips in the sequential connection structure, and the water seepage problem caused by improper treatment of the joints is avoided.
The cement-based polymer not only enhances the structural strength of a single AAC board, but also forms firm connecting strips between adjacent wallboards, thereby improving the overall structural strength of the whole wall body. This makes the wall body more stable when bearing external load, especially shows more excellently in natural disasters such as earthquake.
The AAC material itself has excellent heat insulation performance, and the addition of the cement-based polymer does not affect the property. In contrast, the cement-based polymer has lower heat conductivity coefficient, so that the heat preservation and heat insulation effects of the wall body can be further improved, and the energy consumption of the building can be reduced.
The external baffle plate and the internal baffle plate in the sequential structure design can effectively block gaps between the wall plates and prevent cold air from entering the room from the outside, thereby reducing heat loss and improving the comfort level of the building.
The construction is convenient, the sequential connection structure is simple in design, convenient to construct and suitable for large-scale assembly type building projects. Through standardized production flow, the construction efficiency can be greatly improved, and the construction period is shortened.
The environment-friendly sustainable AAC material and the cement-based polymer are environment-friendly materials, and meet the requirements of green buildings. In addition, the design of the sequential connection structure is beneficial to recycling of resources, reduces the generation of construction waste, and has good environmental benefit.
