[0004] 2. The multifunctional integrated cement-based exterior wall enclosure system is constantly developing at the factory end, but lacks systematic sorting and analysis at the design end, resulting in the inability to carry out systematic design during the construction project design and low design efficiency.

[0005] 3. There is a lack of systematic research on multifunctional integrated cement-based exterior walls, which leads to the lack of a clear optimization direction for the multifunctional integrated cement-based exterior wall enclosure system and the inability to develop in the long run.

In addition, directional terms such as above, below, up, down, upward, downward, left, right, etc. are used with respect to the exemplary embodiments as they are shown in the figures, with the upward or upper direction toward the top of the corresponding figure, and the downward or lower direction toward the bottom of the corresponding figure.

[0033] This embodiment provides a multifunctional integrated cement-based exterior wall enclosure system design method, comprising the following steps:

[0034] S1: Obtain the existing basic information of the building;

[0035] The existing basic information of the building may include the geographical environment, climate characteristics, functions of the building, space, floor plan, facade form, material selection, detail requirements, structural parameters of the integrated cement-based exterior wall system, parameters of the exterior wall structure system, parameters of the insulation system, parameters of the decoration system, etc.

[0036] S2: Establish a classification model for cement-based exterior wall enclosure systems;

[0037] The classification model is established based on the basic information obtained in step S1.

[0038] Model building types include linear models, decision trees, neural networks, etc. After selecting the model type, the basic information of the building obtained above is used as the model input variable, and the type of cement-based exterior wall enclosure system is used as the output. Then the model is evaluated using test data. Common evaluation indicators include accuracy, precision, and recall. In addition, functional evaluation, durability evaluation, safety evaluation, economic evaluation, and process reliability evaluation can also be used as evaluation indicators.

[0039] After the test, the model is optimized according to the evaluation results, which may include adjusting the model structure, adding features, etc. The above model is established by training a large amount of historical data through a specific algorithm. In addition, in other alternative embodiments, the classification model can also be established by manually summarizing the classification.

[0040] S3: Determine the building design requirements and determine the type of cementitious exterior wall enclosure system through a classification model;

[0041] The architectural design requirements include exterior wall enclosure structure system design requirements, insulation system design requirements and decoration system design requirements.

[0042] The enclosure structure system solution is a design solution for building materials and structures based on cement, the insulation system design is a design solution for building materials and structures with insulation performance, and the decoration system design is a design solution for building materials and structures with decorative functions. The design requirements of each system are determined based on specific needs.

[0043] After the architectural design requirements are determined, the basic information of the scheme is determined, such as the design requirements of the building facade, which include the function, form and performance of the building facade. Based on the design requirements of the building facade, the relative relationship between the enclosure structure system and the insulation system is determined, the subdivision type of the decoration system is determined, and the connection method between the decoration system and the main structure is determined;

[0044] The basic information is input into a classification model, and the type of the cement-based exterior wall enclosure system is output through the classification model, and the parameters of the cement-based exterior wall enclosure system are output based on the type of the cement-based exterior wall enclosure system.

[0045] In this embodiment, the parameters of the cement-based exterior wall enclosure system include the connection mode of the prefabricated wall panels, the connection mode of the door and window system and the prefabricated wall panels, and the location and function of the additional structural layer. The parameters are mainly used to determine the mechanical properties of the cement-based exterior wall enclosure system.

[0046] In addition, the parameters of the cement-based exterior wall enclosure system also include the parameters of the integrated cement-based exterior wall (exterior wall type, exterior wall material, etc.), the parameters of the insulation system (insulation method, insulation material, etc.), the parameters of the enclosure system, the parameters of the decoration system (decorative materials, decoration type, etc.), etc.

[0047] S4: Determine whether the type of cementitious exterior wall enclosure system meets the building design objectives;

[0048] In this embodiment, the building design objectives include: determining whether the connection method of the prefabricated wall panels meets the requirements, determining the connection method between the door and window system and the prefabricated wall panels, and determining whether the additional structural layer meets its functional requirements.

[0049] If the building design objectives are met, the cement-based exterior wall enclosure system will be the final solution;

[0050] If the building design goal is not met, the type of cement-based exterior wall enclosure system is readjusted through the classification model. Specifically, the design problems that do not meet the building design goal can be obtained, and the type of cement-based exterior wall enclosure system is readjusted based on the design problems.

[0051] In other alternative embodiments, the building design goal may be a standard related to the cement-based exterior wall enclosure system, such as relevant waterproofing standards, thermal insulation standards, and stress-bearing standards.

[0052] In this embodiment, the subdivision types of the decoration system include heavy decoration type and light decoration type. When the decoration system needs to be connected to the enclosure structure system through a secondary structure, the decoration system is defined as a heavy decoration layer; when the decoration system does not need to be connected to the enclosure structure system through a secondary structure, the decoration system is defined as a light decoration layer.

[0053] When the main body of the enclosure structure system also has a decorative function, it can be defined as a decoration + structural composite layer; when the main body of the enclosure structure system also has a thermal insulation function, it can be defined as a thermal insulation + structural composite layer.

[0054] In this embodiment, the relative relationship between the enclosure structure system and the insulation system includes external insulation type, internal insulation type and self-insulation type. The external insulation type means that the insulation system is located on the outside of the enclosure structure system, the internal insulation type means that the insulation system is located on the inside of the enclosure structure system, and the self-insulation type means that the insulation system is integrated into the interior of the enclosure structure system.

[0055] The following examples illustrate the classification of integrated cement-based exterior wall enclosure systems.

[0056] Taking the main body of the enclosure structure system as the axis, when the insulation system is located on the outside of the main structure of the enclosure structure system, the multifunctional integrated cement-based exterior wall enclosure system is divided into an external insulation system. When the insulation system is located on the inside of the main structure of the enclosure structure system, the multifunctional integrated cement-based exterior wall enclosure system is divided into an internal insulation system. When the main structure of the enclosure structure system has insulation performance at the same time, or the thickness of the cement-based structural layer on both sides of the insulation material is the same, the multifunctional integrated cement-based exterior wall enclosure system is divided into a self-insulating composite wall system.

[0057] In addition, when the integrated cement-based exterior wall is a prefabricated sandwich wall system, when the inner page wall serves as the main body of the enclosure structure system and is connected to the main structure of the building, the multifunctional integrated cement-based exterior wall enclosure system is defined as an external insulation system type; when the outer page wall serves as the main body of the enclosure structure system and is connected to the main structure of the building, the multifunctional integrated cement-based exterior wall enclosure system is defined as an internal insulation system type.

[0058] When the decoration + structure composite layer is located outside the insulation layer, it is classified as an internal insulation system, and a back plate can be added inside the insulation layer to protect the insulation system or decorate the interior.

[0059] Therefore, the external insulation system includes a heavy decorative external insulation wall, a light decorative external insulation wall, a light decorative sandwich external insulation wall, and a sandwich external insulation wall of a decorative structural composite panel extending therefrom.

[0060] Therefore, the internal insulation system includes heavy decorative sandwich internal insulation wall, light decorative sandwich internal insulation wall, heavy decorative internal insulation wall, light decorative internal insulation wall, and their extended decorative structural composite board sandwich wall panels and decorative structural composite board internal insulation wall.

[0061] Classification case 1:

[0062] The building facade of an office building, located in a severely cold / cold region, has ultra-low energy consumption requirements and the stone facade is heavily decorated.

[0063] The design requirements of the above-mentioned design scheme are input into the classification model, the type of cement-based exterior wall enclosure system is output through the classification model, and the parameters of the cement-based exterior wall enclosure system are output based on the type of the cement-based exterior wall enclosure system.

[0064] In extremely cold areas, in order to protect the durability of cement-based wall materials and at the same time ensure the continuity and integrity of thermal insulation materials in the facade, the external insulation system is mainly used. Because the facade is chosen with a stone texture, you can choose a "heavy decorative external insulation wall" in which the stone passes through the insulation layer to connect the concrete wall, or you can choose to use a cement-based imitation stone texture to form a "decorative structural composite panel sandwich external insulation wall".

[0065] Therefore, the classification model may output a heavily decorated external insulation wall or a sandwich external insulation wall with a decorative structural composite panel.

[0066] Among them, the heavily decorated external insulation wall, in this case design, requires the secondary keel to penetrate the insulation layer to form a cold bridge, which will destroy the energy saving of the building. At the same time, it may cause damage to the insulation material and reduce the waterproof performance.

[0067] In this case, the decorative structural composite board mainly imitates the stone material by using cement-based materials on the outer panels to achieve the same facade effect (turning the heavy decoration system to the light decoration system of the composite board). According to the existing FRP connectors, the generation of cold and hot bridges is avoided to ensure the continuity of insulation, while protecting the natural resources of stone, and there is no risk of external hanging falling off. In contrast, in order to ensure the imitation stone effect, higher requirements are placed on the process. Therefore, it is necessary to determine whether the process meets the design requirements based on the division method of stone, scale specifications, texture characteristics, etc.

[0068] If the classification model outputs a heavily decorated external insulation wall, it is necessary to provide an optimized design method for the external decorative keel penetrating the insulation layer connector in the heavily decorated insulation wall system. If the waterproofing standard, insulation standard, and force standard meet the design requirements, the heavily decorated external insulation wall is feasible.

[0069] If you choose to output the sandwich external insulation wall of the decorative structural composite board, you need to provide the process realization methods and cost changes. If the existing process does not meet the above architectural design target requirements, the sandwich external insulation wall of the decorative structural composite board is not feasible, and the heavy decorative external insulation wall is the only option.

[0070] Classification case 2:

[0071] The facade of a school building, located in a climate with hot summers and cold winters, is painted with real stone paint (light decoration).

[0072] The design requirements of the above-mentioned design scheme are input into the classification model, the type of cement-based exterior wall enclosure system is output through the classification model, and the parameters of the cement-based exterior wall enclosure system are output based on the type of the cement-based exterior wall enclosure system.

[0073] In areas with hot summers and cold winters, internal insulation is beneficial to increase indoor temperature faster in order to save energy, so an internal insulation system can be selected. In addition, paint and real stone paint attached to cement-based walls have the advantages of being safer and more durable. Compared with the lightly decorated external insulation wall system, it will not fall off. Therefore, the paint / real stone paint facade can be selected from two types: lightly decorated sandwich external insulation wall and lightly decorated internal insulation wall.

[0074] The lightly decorated sandwich exterior insulation wall has a cement-based inner page board on the indoor side, which helps to improve the waterproofing measures of indoor water-using rooms and protect the insulation layer. Whether in the construction stage or in the use process, the insulation layer can be protected and is easy to connect with the indoor interior partition wall.

[0075] Lightly decorated internal insulation wall, the insulation layer on one side of the room is exposed, and the indoor water-using room needs special structural measures to protect it. During the construction phase, it is necessary to ensure that the insulation material is not damaged. However, the price is more economical than that of lightly decorated sandwich external insulation wall.

[0076] For example, if a lightly decorated sandwich external insulation wall is to be produced, the selection can be further optimized, and the sandwich wall panels of the decorative structural composite panels can be selected. The color and texture are not connected to the outer page panels in an attached form, but are presented through colored concrete or one-time texture molding to improve the durability of the decorative surface. If the existing colored concrete or one-time texture molding method does not meet the design requirements, the sandwich wall panel system of the decorative structural composite panels is not feasible.

[0077] If a lightly decorated interior insulation wall is to be exported, a structural design method must be provided to protect the integrity and durability of the interior insulation materials throughout the process. If the existing structural measures on the inside of the lightly decorated interior insulation wall do not meet the architectural design objectives, the lightly decorated interior insulation wall is not feasible.

[0078] If the output is a light decorative sandwich external insulation wall, and it meets the architectural design objectives, the light decorative sandwich external insulation wall is the only option.

[0079] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0080] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
