Technical Field

[0001] The present application relates to a BIM-based parametric digital forward design method for an interior wall system, and belongs to the technical field of building engineering. Background Art

[0002] With the rapid development of the economy, there is still a large demand for high-quality houses in the construction market. The quality of traditional architectural design methods often depends on the experience and mutual cooperation of professional designers. There are many details that are not considered during the design process due to the lack of experience of designers, which leads to troubles in the later construction. In addition, during the implementation of the project, due to various requirements, it is often necessary to modify the models of various disciplines, which is cumbersome and requires a large amount of modification, and the design efficiency of the building is low.

[0003] Therefore, an innovative BIM-based parametric digital forward design method for interior wall systems is provided to improve design efficiency and quality. Summary of the invention

[0004] In view of this, the present application provides a BIM-based parametric interior wall system digital forward design method. By analyzing the layout and defining parameters, the entire building is divided into multiple levels of component modules according to the system. All component modules are then assembled using the Revit nested family method. Finally, an Excel parametric form is used to link the adjustment of the Dynamo battery-driven model, thereby improving the design efficiency of modular building products.

[0005] Specifically, the present application is implemented through the following scheme: A BIM-based parametric interior wall system digital forward design method comprises the following steps: S1: Analyze the layout according to the research template; S2: define system parameters according to the layout; S3: Split the modules according to the system type, and divide the research samples into multiple levels of component modules according to the system; S4: parametric design system module; S5: Assembling system modules; S6: Enter the parameter drive system module and generate a usable model with one click; Further, as a preference: In S1, a specific dormitory building product was selected as a research model. This type of building has the characteristics of high assembly rate and modularity. Then the standard floor plan of this dormitory building was analyzed, and a concentrated interior wall was selected as the starting point for the research and development of the topic. Then this interior wall was divided into the following subcategories: base wall, flange, wall surface, skirting, door. A parametric component module was formed. In addition, a standard double room module was customized according to the building plan layout. In terms of plan layout, there are mainly key design parameters such as dormitory span, balcony depth, dormitory depth, bathroom span, corridor span, etc.

[0006] In S2, according to the building composition and layout logic, a parameter summary table was constructed, with a total of 146 design parameters, 32 process parameters, and 7 visibility parameters. These include overall parameters, bay depth parameters, floor and roof parameters, roof parameters, foundation wall parameters, structural frame parameters, door and window opening parameters, fine decoration parameters, staircase parameters, etc.

[0007] In S3, take the double room A module as an example. It consists of beams, structural floor slabs, flanges, base walls, building surface layers, beam cladding, wall surface layers, skirtings, ceilings, doors and windows, PC exterior walls, etc.

[0008] In S4, the first floor of the building is innovatively divided into four modules: stairwell module (first floor), standard middle base wall plus surface module (first floor), standard column span with room modules on both sides (first floor), and side span double room assembly module (first floor). The second floor of the building is divided into four modules: stairwell module (second floor), standard middle base wall plus surface module, standard column span with room modules on both sides, and side span double room assembly module. The standard floor is divided into four modules: stairwell module (standard floor), standard middle base wall plus surface module, standard column span with room modules on both sides, and side span double room assembly module. The top floor is divided into stairwell module (top floor), standard middle base wall plus surface module, standard column span with room modules on both sides, and side span double room assembly module (top floor). For the roof floor, it is divided into three different modules: the module above the roof stairwell, the module above the roof standard room, and the module above the roof side span double room.

[0009] In S5, first, the component modules are assembled into single-layer modules, and then the single-layer modules are assembled into a model of the entire building.

[0010] In S6, the Excel parametric form is linked to the adjustment of the Dynamo battery drive model. This drive method consists of three parts: 1. Revit assembly model, which includes the system module parametrically designed in step S4 of the parametric interior wall system digital forward design method. 2. Parametric interior wall system digital Dynamo assembly battery, which is associated with the R&D parameter summary table and the Revit assembly model. 3. R&D summary parameter table, including design parameters and fixed parameters.

[0011] The overall design process is as follows: the designer enters the relevant design parameters in the R&D parameter summary table, clicks to save the Excel R&D parameter summary table, and this R&D parameter summary table is associated with the parametric interior wall system digital Dynamo assembly battery program. Click to run the parametric interior wall system digital Dynamo assembly battery program, and Dynamo can be used to drive Revit to quickly generate a model that matches the parameters.

[0012] The corresponding civil engineering quantity information is also attached to the model.
