Description

Technical Field

[0001] The invention relates to a method and system for generating a special-shaped concrete structure template. Background Art

[0002] As special-shaped building structures are increasingly used in various fields, it is crucial to ensure the feasibility, safety, and quality of formwork construction at key locations of special-shaped concrete structures.

[0003] The specifications of formwork modules in the construction industry are unified. Compared with the step-by-step construction of formwork in traditional regular buildings, the construction of formwork in key parts of thin-shell structures requires large-scale building structures to have different curvatures in different parts. However, due to the uneven professional quality of on-site construction workers, on-site weather temperature and humidity, and inaccurate cutting of formwork, it is common to fail to meet specific structural curvature requirements, have messy formwork seams, and experience uneven vibration, which seriously affects construction quality and cost. Summary of the Invention

[0005] To solve the above problems, the present invention provides a method for generating a special-shaped concrete structure formwork, comprising:

[0006] Step S1, selecting the lower surface layer of the special-shaped concrete structure;

[0007] Step S2, dividing the lower surface layer of the selected special-shaped concrete structure based on the module of the standard formwork to obtain a divided surface layer;

[0008] Step S3, extracting four coordinate points of each surface layer from the divided surface layers;

[0009] Step S4, generating a construction template model based on the four coordinate points of each surface layer and the thin shell shape of the special-shaped concrete structure;

[0010] Step S5, calculating the buckling degree of each surface layer template according to the four coordinate points of each surface layer template in the construction template model;

[0011] Step S6, determining whether the buckling of each surface template in the construction template model exceeds a preset construction tolerance, if so, the buckling does not meet the requirement;

[0012] Step S7: If the preset construction tolerance is exceeded, the process returns to step S2 and begins again;

[0013] Step S8: If the preset construction tolerance is not exceeded, the four endpoint coordinates of each surface template in the adaptive template model are exported to the corresponding surface template model, and the ID of the surface template, the length of each side of the surface template, and the four endpoint coordinates of each surface template are extracted from each surface template model to facilitate the subsequent design and cutting construction preparation of the special-shaped concrete structure.

[0014] Furthermore, in the above method, step S1, selecting the lower surface layer of the special-shaped concrete structure, includes:

[0022] Furthermore, in the above method, the buckling degree is the vertical distance from one of the four coordinate points of each surface layer template to a plane formed by the other three coordinate points.

[0023] Furthermore, in the above method, step S5, calculating the buckling of each surface layer template based on the four coordinate points of each surface layer template in the construction template model, includes:

[0024] The four points of each surface layer template are divided into two groups. The first group is to take three coordinate points of the four coordinate points of each surface layer template, and use Plane.ByThreePoints to form a projection surface; the second group is to take the remaining coordinate point of the four coordinate points of each surface layer template, and use the Surface.ProjectInputOnto projection function to project the points of the second group onto the projection surface to obtain projection points, and calculate the length, i.e., the curvature, of the projection point of each surface layer template and the coordinate points in the second group of the surface layer template respectively.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 5 As shown, the present invention provides a method for generating a special-shaped concrete structure template, comprising:

[0048] Step S1, selecting the lower surface layer of the special-shaped concrete structure;

[0049] Here, the Select Face node in Dynamo can be used to select the lower surface layer of the special-shaped concrete structure;

[0050] Step S2, dividing the lower surface layer of the selected special-shaped concrete structure based on the module of the standard formwork to obtain a divided surface layer;

[0051] Here, if Figure 2 As shown, based on the module of the standard template, it is divided into lines in the horizontal and vertical directions to obtain the divided horizontal and vertical lines; the Intersection.GeometrySplit node in Dynamo is used to cut according to the divided horizontal and vertical lines to obtain the divided surface layer;

[0052] Step S3, extracting four coordinate points of each surface layer from the divided surface layers;

[0053] Here, if Figure 3 As shown, the WH_Surface.DeconstructSurface node in Dynamo is used to extract the four coordinate points of each surface layer from the divided surface layer;

[0054] You can use the WH_Surface.DeconstructSurface node to represent the divided surface layer in the form of spatial coordinate points;

[0055] Step S4, generating a construction template model based on the four coordinate points of each surface layer and the thin shell shape of the special-shaped concrete structure;

[0056] Here, based on the four coordinate points of each surface layer and the thin shell shape of the special-shaped concrete structure, the adaptive node AdaptiveComponent.ByPoints is used to generate a BIM construction template model in Dynamo;

[0057] Step S5, calculating the buckling of each surface layer template based on the four coordinate points of each surface layer template in the construction template model, wherein the buckling is the vertical distance from one of the four coordinate points of each surface layer template to the plane formed by the other three coordinate points;

[0058] Here, the curvature of the surface template is calculated based on the coordinates of each surface template: the four points of each surface template are divided into two groups. The first group is to take three coordinate points from the four coordinate points of each surface template, and use Plane.ByThreePoints to form a projection surface with the three coordinate points; the second group is to take the remaining coordinate point from the four coordinate points of each surface template, and use the Surface.ProjectInputOnto projection function to project the points of the second group onto the projection surface to obtain projection points. The length of the projection point of each surface template and the coordinate points in the second group of the surface template, that is, the curvature, is calculated respectively. The larger the curvature value, the greater the degree of curvature of the surface area, and the more refined the template segmentation needs to be.

[0059] Step S6, determining whether the buckling of each surface template in the construction template model exceeds a preset construction tolerance, if so, the buckling does not meet the requirement;

[0060] Here, the preset construction tolerance is -5mm to 10mm;

[0061] like Figure 4 and 5 As shown, the present invention can realize data visualization: the numerical value of the buckling degree is used to represent the allowable error of the template construction, and different colors can be used to represent different buckling degree intervals in the BIM model. The numerical value is represented by color, which can more intuitively express the key and difficult areas of construction.

[0062] Step S7: If the preset construction tolerance is exceeded, the process returns to step S2 and begins again;

[0063] Here, the present invention can perform secondary segmentation on the surface layer of the adaptive template model that does not meet the required buckling degree, and then repeat the buckling degree calculation, judgment and segmentation process on the secondary segmented surface layer until the buckling degree of all surface layers in the adaptive template model does not exceed the preset construction tolerance.

[0064] The present invention can filter and screen based on the degree of buckling: the degree of buckling is equivalent to the construction tolerance (-5mm to 10mm), and the greater the degree of buckling, the greater the construction tolerance (-5mm to 10mm). Interval filtering and screening is performed based on the value of the degree of buckling, and different colors are used to represent different degree of buckling intervals using the Element.OverrideColorInView and UI.ColorPicker nodes to distinguish the surface template areas with construction tolerances; based on the degree of buckling, the surface template ID that exceeds the construction tolerance is filtered and screened, and the surface template is regenerated by halving the modulus of the standard template, and the degree of buckling is regenerated and screened, and this process is repeated until the degree of buckling meets the construction tolerance.

[0065] Step S8: If the preset construction tolerance is not exceeded, the four endpoint coordinates of each surface template in the adaptive template model are exported to the corresponding surface template model, and the ID of the surface template, the length of each side of the surface template, and the four endpoint coordinates of each surface template are extracted from each surface template model to facilitate the subsequent design and cutting construction preparation of the special-shaped concrete structure.

[0066] Here, if Figure 6 As shown in the figure, if the preset construction tolerance is not exceeded, the four endpoint coordinates of each surface layer template in the adaptive template model will be exported to the corresponding surface layer template model in Revit. At the same time, the Excel.WriteToFile node will be used to output the ID of the surface layer template in the surface layer template model, the length of each side of the surface layer template, and the four endpoint coordinates of each surface layer template to Excel for easy material cutting statistics.

[0067] The purpose of the present invention is to provide a method for analyzing the construction requirements of templates for different curvatures before the construction of templates for special-shaped concrete structures, intelligently analyze the blanking of templates in different areas, determine the feasibility of template construction, and ensure construction quality. The present invention can realize the forward digitization of the model, generate a construction template model by segmenting the model surface, and fit the model of the surface layer template using each surface layer in the construction template model within the construction tolerance (-5mm to 10mm). The template ID, the length of each side of the template, and the endpoint coordinates of each fitted template are exported to an Excel table. This method is particularly effective in the statistical process of subsequent template blanking for areas with large curvature, high construction difficulty, and high construction precision.

[0068] The present invention has wide adaptability. When any change occurs to the model of the surface template, the data in Excel will change immediately. The data in Excel and the model are linked to generate a template that meets the construction tolerance (-5mm to 10mm). The corresponding surface template model contains relevant data information, and the corresponding data is exported to the Excel table. At the same time, the present invention can be applied to any thin shell and curtain wall structure analysis.

[0069] The present invention is convenient for construction, can speed up the processing and deepening efficiency of the template, ensure lossless turnover of the template, reduce template loss, reduce template construction joints, facilitate construction personnel to cut materials, facilitate on-site construction and assembly, and improve the on-site concrete construction quality of curved surface structures.
