[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1 to Figure 2 As shown, the method of judging whether a complex node is reasonable through a three-dimensional visualization model in this embodiment includes the following steps:

[0025] Step S1, identify the complex node area according to the drawing and obtain the component data information of the complex node.

[0026] Specifically, in step S1, the structural plan is combined with the node detail drawing to identify the area as a complex node based on the intersection of multiple beams and the variable diameter column caps of the columns in the node detail drawing. For the complex node area, according to the structural plan, the cross-sectional dimensions of the beams intersect with the column cap nodes of the variable diameter columns and have structural walls, and the components in the area set at the fire partition are analyzed, and the areas with greater construction difficulty are identified as nodes in complex areas. In this embodiment, when more than four beams 201 intersect the same column 202 at the same elevation, the upper section of the column uses the upper section of the four-sided pyramidal column cap to analyze the complex nodes, and obtain information such as beams 201, columns 202, floor slabs 203, surrounding walls 204 and surrounding fire doors 205.

[0027] Step S2: using the data information obtained from the complex nodes, the complex nodes are split to obtain data information of basic geometric shapes required for creating a three-dimensional model.

[0028] Specifically, step S2 splits the complex nodes to obtain data information of basic geometric shapes required to create a three-dimensional model, including: the beams of the complex nodes in this example are more than four beams 201 intersecting with the same special-shaped column 202 at the same elevation, and the cross-sectional heights of the beams 201 are different. The splitting of the beams is mainly carried out according to the different cross-sectional sizes of the beams. Through the component data information obtained in step S1, the beams are classified and split according to their geometric sizes and encoded.

[0029] like Figure 2 As shown, the complex node column of this example is a special-shaped column. According to the construction drawings, a quadrangular cone-shaped column cap is used for the situation where more than four beams intersect the same column. According to the wall column plan, there are two column forms: a circular column and a square column. The column 202 of this embodiment is a circular column. According to the deepened column construction drawing, the circular column is divided into three parts. The circular column includes an upper quadrangular cone-shaped column cap 211, a truncated cone-shaped middle section 212 and a lower circular main column 213 from top to bottom. The height of the upper quadrangular cone-shaped column cap is 1100mm higher than the floor slab. The upper opening of the upper quadrangular cone-shaped column cap is square, and the side length of the upper opening is 2200mm plus the column width of the lower section. The lower opening of the upper quadrangular cone-shaped column cap is square, and the side length of the lower opening is 150mm plus the column width; the upper opening of the middle truncated cone is circular, and the diameter of the upper opening is 300mm plus the column width of the lower section, and the diameter of the lower opening is the column width of the lower section. Columns of different sizes are classified and coded according to the corresponding detailed drawings of complex node locations.

[0030] Floor 203 checks whether there is any functional requirement for splitting the slab according to the node position in the drawing, and identifies and splits the information of lowering the slab and the slab thickness.

[0031] The relevant information of the fire door 205 in the complex node area is split and the data information is obtained.

[0032] Step S3, using the data information of the basic geometric shape, create a parametric model of a complex node component in the Revit software and establish a parametric model library. Specifically, it includes the following contents:

[0033] Creation of beams, slabs, and walls: Use the parametric model provided by the Revit software. According to the size information of the drawing, enter the parameters of each component type to form a parametric family library to provide support for retrieving the model in step S4.

[0034] Column establishment: For the circular column in this embodiment, the column model family template is used. The upper quadrangular pyramid column cap adopts the lofting fusion command in the shape creation module. First, a path is drawn along the center line, that is, the height of the upper quadrangular pyramid column cap is 1100mm. Draw the upper contour 1 according to the drawing size (the upper size of the upper quadrangular pyramid column cap, the side length is 2200mm plus the width of the lower circular main column), draw the upper contour 2 (the lower size of the upper quadrangular pyramid column cap, the side length is 150mm plus the width of the lower circular main column, the height of the upper quadrangular pyramid column cap is 1100mm). The dimensions are set as fixed parameters according to the drawings. The upper and lower dimensions of the upper quadrangular cone-shaped column cap can be adjusted parametrically according to the dimensions of the lower circular main column. The height of the middle section of the truncated cone is a fixed dimension of 800mm in the drawings. The diameter of the lower truncated cone is the width of the lower circular main column. The upper dimension of the truncated cone is the diameter of 300mm plus the width of the lower section. The cross section of the lower circular main column is circular. The lower circular main column uses the stretch command in the Create Shape module. The height is based on the drawing layer height minus the height of the upper and middle sections. The plane dimensions are defined according to the dimensions of the drawings.

[0035] Fire door establishment: Use the fire door model family provided by Revit software, and create parametric modifications according to the drawing requirements. Fire doors use fire shutter doors, and the shutter method uses a scroll form. Determine the size of the upper shutter box of the fire door according to the design drawing requirements and the product information provided by the manufacturer.

[0036] Step S4: retrieve the component model of the parametric model library based on the drawing position information to quickly build the basic model of the complex node, specifically including: retrieve the basic model of the family library model according to the drawing axis positioning, and adjust the parameters of the basic model according to the drawing parameters.

[0037] Step S5, performing collision analysis on the basic model of the complex node to obtain a detailed model of the complex node. Specifically, it includes: connecting the columns, beams, plates, walls, and fire doors of the basic model of the complex node in the software, so that the basic models will overlap after the connection, connecting the overlapping basic models in the geometric graphics module of the three-dimensional software, and cutting the overlapping parts of the basic models, fusing the models of each component into the basic model of the complex node, analyzing and deepening the basic model, and obtaining a detailed model of the complex node.

[0038] Step S6, analyze the detailed model of the complex node to determine whether the drawing is reasonable. Step S5 is used to deepen the complex node model of the basic model, and the basic model is reviewed in combination with the construction drawings. The collision analysis columns, beams, plates, fire doors, and walls are integrated into the detailed model of the complex node. The detailed model is analyzed and judged. If it is determined that the upper quadrangular pyramid column cap collides with the fire door, the drawing is judged to be unreasonable, and the drawing is further changed and adjusted.

[0039] Step S7: If the drawing is judged to be reasonable, the drawing is produced based on the detailed model of the complex node. At the same time, the contour edge of each component is generated by connecting and cutting to generate accurate geometric shapes, and the detailed drawing is generated according to the component position positioning and marking. The drawing output module of the 3D software is used to export the drawings, 3D drawings and the engineering quantity data of the concrete volume according to the construction site. The on-site construction personnel are briefed, and the technical explanation of the 3D model is given to the engineering management personnel and construction personnel.

[0040] Example 2

[0041] like Figure 1 and Figure 3 As shown, the method of judging whether a complex node is reasonable through a three-dimensional visualization model in this embodiment includes the following steps:

[0042] Step S1, identify the complex node area according to the drawing and obtain the component data information of the complex node.

[0043] Specifically, in step S1, the structural plan is combined with the node detail drawing to identify the area as a complex node based on the intersection area of ​​multiple beams and the variable diameter column caps of the columns in the node detail drawing. For the complex node area, according to the structural plan, the cross-sectional dimensions of the beams intersect with the column cap nodes of the variable diameter columns and have structural walls, and the components of the area set at the fire partition are analyzed, and the areas with greater construction difficulty are identified as nodes in complex areas. In this embodiment, when more than four beams 201 intersect the same column 202 at the same elevation, the upper section of the column uses the upper section of the four-sided pyramidal column cap to analyze the complex nodes, and obtain information such as beams 201, columns 202, floor slabs 203, surrounding walls 204 and surrounding fire doors 205.

[0044] Step S2: using the data information obtained from the complex nodes, the complex nodes are split to obtain data information of basic geometric shapes required for creating a three-dimensional model.

[0045] Specifically, step S2 splits the complex nodes to obtain data information of basic geometric shapes required to create a three-dimensional model, including: the beams of the complex nodes in this example are more than four beams 201 intersecting with the same special-shaped column 202 at the same elevation, and the cross-sectional heights of the beams 201 are different. The splitting of the beams is mainly carried out according to the different cross-sectional sizes of the beams. Through the component data information obtained in step S1, the beams are classified and split according to their geometric sizes and encoded.

[0046] like Figure 3 As shown, the complex node column of this embodiment is a special-shaped column. According to the construction drawings, a quadrangular pyramid-shaped column cap is used when more than four beams intersect the same column. The column 202 of this embodiment is a square column. According to the deepened column construction drawings, the circular column is divided into three parts, and the square column is divided into three parts: an upper quadrangular pyramid-shaped column cap 211, a quadrangular pyramid-shaped middle section 222, and a lower square main column 223. The height of the upper quadrangular pyramid cap is 1100mm below the floor slab. The upper opening of the upper quadrangular pyramid cap is square, and the side length of the upper opening is 2200mm plus the column width of the lower section. The lower opening of the upper quadrangular pyramid cap is square, and the side length of the lower opening is 150mm plus the column width of the lower section. The height of the middle quadrangular pyramid is 800mm. The upper opening of the middle quadrangular pyramid is square, and the upper opening size of the middle quadrangular pyramid cap is the lower opening size of the upper quadrangular pyramid cap. The lower opening of the middle quadrangular pyramid is square, and the side length of the lower opening size is the column width of the square main column of the lower section. The cross section of the square main column of the lower section is square. According to the corresponding detailed drawings of the complex node positions, the columns of different sizes are classified and coded.

[0047] Floor 203 checks whether there is any functional requirement for splitting the slab according to the node position in the drawing, and identifies and splits the information of lowering the slab and the slab thickness.

[0048] The relevant information of the fire door 205 in the complex node area is split and the data information is obtained.

[0049] Step S3, using the data information of the basic geometric shape, create a parametric model of a complex node component in the Revit software and establish a parametric model library. Specifically, it includes the following contents:

[0050] Creation of beams, slabs, and walls: Use the parametric model provided by the Revit software. According to the size information of the drawing, enter the parameters of each component type to form a parametric family library to provide support for retrieving the model in step S4.

[0051] Column establishment: For the square column of this embodiment, a template based on the column model family is used. The upper quadrangular pyramid-shaped column cap adopts the lofting fusion command in the shape creation module. First, a path is drawn along the center line. The path is the height of the upper quadrangular pyramid-shaped column cap. The upper contour 1 is drawn according to the drawing size (the upper opening size of the upper quadrangular pyramid-shaped column cap, the side length is 2200mm plus the column width of the lower square main column), and the upper contour 2 is drawn (the lower opening size of the upper quadrangular pyramid-shaped column cap, the side length is 150mm plus the column width of the lower square main column). The height of the upper quadrangular pyramid-shaped column cap is set as a fixed parameter according to the drawing. The upper and lower opening sizes of the upper quadrangular pyramid-shaped column cap can be parametrically adjusted according to the size of the lower square main column. The quadrangular pyramid-shaped middle section is the same as the upper quadrangular pyramid-shaped column cap. The height is the fixed size of 800mm in the drawing. The side length of the upper opening size of the quadrangular pyramid-shaped middle section is the side length of the lower opening size of the upper quadrangular pyramid-shaped column cap, and the lower opening size of the quadrangular pyramid-shaped middle section is the column width of the lower square main column. The square main column in the lower section is created using the stretch command in the shape creation module. The height is determined by subtracting the height of the upper and middle sections from the drawing layer height, and the plane size is defined according to the size of the drawing.

[0052] Fire door establishment: Use the fire door model family provided by Revit software, and create parametric modifications according to the drawing requirements. Fire doors use fire shutter doors, and the shutter method uses a scroll form. Determine the size of the upper shutter box of the fire door according to the design drawing requirements and the product information provided by the manufacturer.

Specifically, it includes: connecting the columns, beams, plates, walls, and fire doors of the basic model of the complex node in the software, so that the basic models will overlap after the connection, connecting the overlapping basic models in the geometric graphics module of the three-dimensional software, and cutting the overlapping parts of the basic models, fusing the models of each component into the basic model of the complex node, analyzing and deepening the basic model, and obtaining a detailed model of the complex node.

[0055] Step S6, analyze the detailed model of the complex node to determine whether the drawing is reasonable. Step S5 is used to deepen the complex node model of the basic model, and the basic model is reviewed in combination with the construction drawings. The collision analysis columns, beams, plates, fire doors, and walls are integrated into the detailed model of the complex node. The detailed model is analyzed and judged. If it is determined that the upper quadrangular pyramid column cap collides with the fire door, the drawing is judged to be unreasonable, and the drawing is further changed and adjusted.

[0056] Step S7: If the drawing is judged to be reasonable, the drawing is produced based on the detailed model of the complex node. At the same time, the contour edge of each component is generated by connecting and cutting to generate accurate geometric shapes, and the detailed drawing is generated according to the component position positioning and marking.
