Description

Technical Field

[0001] This invention relates to the field of information-based design technology for building structures, and in particular to a parametric modeling method for structural insulation panel curtain walls. Background Technology

[0002] With the acceleration of the industrialization of construction, structural insulation panels (SIPs) have been widely used in prefabricated buildings, low-energy buildings and modular buildings due to their excellent thermal insulation performance and structural load-bearing capacity.

[0003] In daily practice, the existing technical solutions have been found to have the following problems: During the architectural design process, designers need to manually draw each SIP (Structured Indicator Panel) segment. For large-scale applications, this is a huge workload and prone to errors. In addition, when changes occur in the architectural design, such as changes in the location or size of door and window openings, all related SIP segments need to be manually readjusted, resulting in poor coordination and being time-consuming and labor-intensive.

[0004] Therefore, it is necessary to provide a new technical solution to solve the above problems. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides a parametric modeling method for structural insulation panel curtain walls.

[0008] Optionally, the geometric parameters of the building facade outline include the width, height, thickness, and edge information of the building facade.

[0009] Optionally, in step S3, the attribute information includes the unique ID code, size specifications, coordinate position in the facade, insulation core material type, and surface material of each structural insulation board.

[0010] Optionally, in step S4, the contents of the bill of materials are dynamically updated as the model changes.

[0011] Optionally, when the geometric parameters and layout rules of the curtain wall change, the system automatically performs a linked update to achieve rapid reconstruction of the entire SIPs curtain wall model.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1 As shown, a parametric modeling method for structural insulation panel curtain walls includes: Step S1: Establish a parametric driving framework for the structural insulation panel curtain wall panel and set the core driving parameters.

[0018] The parametric driving frame for structural insulation panel curtain wall panels refers to establishing a relationship between the dimensions of each part of the panel and the parameters, and being able to control the model by adjusting the parameters.

[0019] In this embodiment, structural insulation panels (SIPs) are used as panels. This process is implemented based on Revit software. The parametric driving framework is mainly implemented by applying core functional modules such as reference planes / lines, dimension parameters, associative formulas, and nested families in the family editor.

[0020] The core driving parameters include the geometric parameters of the building facade outline, the specifications of the structural insulation board, and the layout rules.

[0021] It is achieved through the following steps: S11. Create the curtain wall panel family frame.

[0022] Choose the correct family template: When creating a new family in Revit, select "Metric Curtain Panel" as the starting point. This template ensures that the family is correctly identified as a curtain panel and automatically embedded into the curtain wall grid.

[0023] Define the driving skeleton: Use "reference plane" or "reference line" to draw the main framework that controls the position and size of the panel and internal components (such as panels, insulation layer, keel, and glue joint), and use the "align" function to lock the reference plane with the center or boundary provided by the family template to establish the constraint benchmark.

[0024] S12. Establish parameterized logic.

[0025] Add dimension parameters: Use "Align Dimensions" to add dimensions to the reference plane being drawn and create it as a family parameter. Family parameters include panel width, insulation thickness, etc.

[0026] Writing driving formulas: In the "Family Type" dialog box, you can assign values ​​to core driving parameters or write formulas for other dimensional parameters to establish geometric relationships. For example, by using the formula: Joint Width = 2 * a, the width of the entire joint can be controlled by a basic parameter 'a'. Similarly, other driving formulas are written using this logic.

[0027] S13, Refine the panel composition.

[0028] Creating the main geometric model: Based on a reference plane with added parameters, use commands such as "Extrude," "Merge," and "Loft" to create the main shape of the panel, i.e., the main shape of the structural insulation panel. Lock its boundaries to the corresponding reference plane when drawing the outline. This way, the geometric model will update accordingly when the parameters change.

[0029] Nested family assembly: For complex components within a panel, individual families can be created, then loaded and nested into the main panel family. Specific operations include: Create separate families for internal components. Load the component families into the main panel family, place them, and use the "Align" command to position and lock them on the corresponding reference plane. The most crucial step is to associate the size parameters of this nested family with the predefined parameters in the main family, ensuring that it is also completely driven by the main family's parameters. In addition to basic shapes, "Hollow Shapes" can be used to cut out machining details such as mounting slots and chamfers, and loaded into the project to assign realistic materials and appearances to each component.

[0030] During implementation, the geometric parameters of the building facade outline include the width, height, thickness, and edge information of the building facade to be fitted with the curtain wall.

[0031] The layout rules parameters are determined based on the design requirements, including the edge parameters of the boards and the parameters for the reserved gaps between the boards.

[0032] The parameters for the reserved joint between panels include the reserved joint width on the left and right sides of the insulation structure panel. These parameters are used to control the gap between panels and the installation tolerance, while also taking into account the thermal expansion and contraction of the panels and the requirements for waterproof sealing. The size range of the reserved joint width is 1mm to 6mm.

[0033] When creating a family of thermal insulation structural panels, the panel material, insulation material, and dimensional parameters must be defined according to the design requirements.

[0034] The panel consists of an inner panel and an outer panel that are parallel to each other. The insulation layer is located between the inner panel and the outer panel and is tightly connected to the inner panel and the outer panel by the adhesive generated during the polyurethane rigid foam foaming process.

[0035] The panel material should preferably be a material with good mechanical properties, including but not limited to high-density cement fiberboard, OSB board, MgO board, metal plate, etc., and its thickness and specifications should be determined according to design requirements and mechanical properties.

[0036] The insulation material is the material used for the insulation layer, and the appropriate material is selected according to national standards and design requirements.

[0037] The dimensional parameters include the total thickness of the insulation structure panel, the thickness of the inner panel, the thickness of the outer panel, the size of the upper connector, the size of the lower connector, the size of the first side connector, the size of the second side connector, the location and size of the conduit.

[0038] In addition, the joint shape of the thermal insulation structural panel is determined by the size and form of the connector. The default is a tongue and groove structure. When the joint of the thermal insulation structural panel is a flat or groove structure, the upper joint, lower joint, first side joint, and second side joint are set to 0.

[0039] The conduit system includes vertical and horizontal conduits, with the horizontal conduits connected to the vertical conduits. Horizontal conduits are those that penetrate the insulation layer horizontally. The positional dimension of the horizontal conduit refers to the distance from the centerline of the vertically embedded conduit to the bottom of the slab on the vertical surface, determined by the location of the switches and sockets.

[0040] Vertical conduits are installed on the left and right sides of the insulation layer. The size of the vertical conduits is the radius of the internal pre-embedded conduits, which is not strictly limited, as long as it is smaller than the thickness of the insulation layer.

[0041] Step S2: Based on the geometric parameters and layout rules of the curtain wall, automatically generate grid lines using Revit software to define the boundaries and joint positions of each structural insulation board.

[0042] In Revit software, a curtain wall system instance is created. Through the platform's built-in algorithm or a secondary development plugin, the geometric contour parameters and layout rule parameters defined in step S1 are mapped to the vertical and horizontal segmentation grid of the curtain wall.

[0043] Step S3: Based on the divided mesh, automatically generate a 3D model of each structural insulation board and assign attribute information to each structural insulation board.

[0044] Based on the curtain wall mesh generated in step 2, the Revit software system automatically identifies each mesh element and calls the structural insulation board curtain wall panel family created in step 1 to generate a corresponding 3D instance of SIPs board for each mesh element.

[0045] At the same time, the system automatically assigns geometric and non-geometric attribute information to each generated structural insulation board according to the parameter system defined in step 1.

[0046] The non-geometric attributes of the structural insulation board include unique ID code, size specifications, coordinate position in the facade, type of insulation core material, material of inner and outer panels, fire rating, weight, production batch, etc.

[0047] The built-in algorithms in Revit software ensured panel seam alignment and optimal specifications, avoiding human error and resulting in a high degree of standardization in design outcomes, which is conducive to industrial production.

[0048] Step S4: Automatically generate a bill of materials associated with the structural insulation panel curtain wall.

[0049] The parameters required for the Bill of Materials (BOM) that are dynamically associated with the model, such as floor, function, and notes, can be shared parameters, or Revit's built-in parameters such as width, height, quantity, area, notes, and tags can be used to export the parameter table of the required materials.

[0050] If the parameter table is exported using Revit software, its format is TXT. Alternatively, you can use a plugin to export it to Excel or other formats as needed.

[0051] Furthermore, relying on Revit software, the bill of materials is dynamically updated as the model changes. That is, when the geometric parameters and layout rules of the curtain wall change, the system automatically performs a linked update, enabling rapid reconstruction of the entire SIPs curtain wall model.

[0052] Example

[0053] In this embodiment, the thermal insulation structural panel is as follows: Figure 2 and Figure 3 As shown, The structural insulation panel curtain wall panel includes an inner panel, an outer panel, an insulation layer, and several conduits.

[0054] The inner and outer panels are cubic. The outer contour of the insulation layer has concave grooves on both sides. These concave grooves serve as vertical conduits. Horizontal conduits penetrate the insulation layer from left to right at predetermined positions and are connected to the vertical conduits.

[0055] This embodiment sets up 3 horizontal conduits and 2 vertical conduits. The 3 horizontal conduits are the first horizontal conduit, the second horizontal conduit, and the third horizontal conduit, and the 2 vertical conduits are the first vertical conduit and the second vertical conduit.

[0056] The shape of the joint at the edge of the thermal insulation structural panel is determined by the size and form of the connector; in this embodiment, it is a tongue and groove shape.

[0057] In addition, the joint shape at the edge of the insulation structural panel can also be set to a flat opening or a groove. In Revit software, the joint parameter can be set to 0.

[0058] Parameters related to the inner panel include: inner panel thickness and panel material. Parameters related to the outer panel include: outer panel thickness and panel material. Parameters related to the insulation layer include: upper connector, lower connector, first side connector (connector 1), second side connector (connector 2), pipe diameter, pipe groove, SIPs board thickness, and insulation material. Parameters related to the conduit include: position of the first horizontal conduit (conduit 1), position of the first horizontal conduit (conduit 2), and position of the third horizontal conduit (conduit 3). Specifically, the upper connector represents the contact height with the top connector, the lower connector represents the contact height with the bottom connector, connector 1 represents the contact length with the left connector, and connector 2 represents the contact length with the right connector. The pipe diameter represents the radius of the built-in conduit, the pipe groove represents the length and depth reserved for the conduit on both sides of the insulation layer, and the positions of conduit 1, 2, and 3 represent the distance from the center of the conduit to the bottom of the board.

[0059] In addition, the corresponding parameters also include gap 1 and gap 2. Gap 1 represents half the width of the pre-reserved gap with the left wall panel, and gap 2 represents half the width of the pre-reserved gap with the right wall panel. Considering the thermal expansion and contraction of the panels and the requirements for waterproof sealing, gaps 1 and 2 should be 1mm to 6mm.

[0060] Set the parameters for each part in sequence, set it as Instance 1 and name it as follows: Figure 4 As shown, change the parameters, set them to instance 2, 3, ... and name them.

[0061] Load the Revit software, draw the wall, select the curtain wall, set the curtain wall panel to this panel, set the vertical and horizontal grids, and draw the wall panel at the target location, such as... Figure 5 As shown.

[0062] The curtain wall panel list in the model accurately records the basic parameters of the panels, including but not limited to length, height, area, quantity, and annotations, providing basic data for production and quantity calculation. After loading the panel markings, panels can also be marked on the floor plan.

[0063] In Revit software, click "View," then "Schedule," then "Schedule / Quantity." Select "Curtain Wall Panels" as the category and click "OK." In "Available Fields," select the fields you want to analyze, including but not limited to: Family, Type, Width, Height, Area, Total, Notes, Conduit 1 Location, Conduit 2 Location, Conduit 3 Location, etc., and add them to the "Schedule Fields." Click "OK," and the system will automatically generate a schedule for curtain wall panels, such as... Figure 6 As shown.

[0064] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
